INTRODUCTION
The TTC-1000, 3 Probe Transformer Temperature Controller is a mission
specific programmable controller that measures up to three different probe
temperatures, load and calculated winding temperature. The user can program
six (6) independent outputs based on the state of pre-programmed temperature
set points, time set points, load set points or the outputs themselves. The
controller can measure any three of top oil, winding, LTC tank, or ambient
temperature to accuracy of ± 1 ºC and does not require calibration. Calculated
winding temperature is based on the methods of ANSI C57.91 and uses
measured top oil temperature and load current.
The outputs can be used to:

Control cooling fans and pumps.

Provide high temperature, LTC condition, and cooling system performance
alarms.

Provide a trip output.
The TTC-1000 is substation hardened and designed to operate over a wide
temperature range of –35 to 85 ºC suitable for installation in outdoor cabinets.
The TTC-1000 contains many features including:

Measures temperature from -35 to 160 ºC.

Does not require calibration.

Optional 0-1 or 4 - 20 mA analog outputs.

Up to three temperature probes.

Optional aux CT input for calculated winding temperatures.

Load pickup set points for early activation of cooling based on sudden
increases in load.

Comprehensive LTC condition monitoring for the detection of both slowly and
quickly evolving problems.

Universal probe kit includes thermo well fitting adapters and probe sleeves.

Optional magnetic mount temperature probe (for when a thermo well is not
available).

Reports Min and Max Temperatures, time stamped with date and time.

Data logging.

Periodic exercise of cooling fans.

Automatic swapping of lead and lag fan banks.

Four independent temperature set points per probe.
1
V5.204, March 11, 2008

Cooling system performance monitor to alarm when cooling is commanded
but the current draw of the cooling fans or pumps is outside a specified
range.

Six scheme logic programmable form C relay outputs, all trip duty rated.

Dedicated programmable alarm relay.

Remote/Local Comms through RS-232, no special software required.

Flash memory for convenient firmware upgrades.

Same unit operates from 38 to 160VDC or 120VAC and is immune to
reversal of battery voltage polarity.

Available in either compact panel mount or a 304 Stainless Steel NEMA 4X
enclosure.

Optional DNP3.0 Level 1 communications for reading analogs plus status
and remotely commanding cooling via RS-485 or Multi-Mode Fiber Optics.

Two optional optically isolated inputs for remote cooling control by SCADA,
reporting status from liquid level or sudden pressure alarms over DNP3.0, or
for selective blocking of outputs.

Each TTC-1000 is burnt-in for a total of 48 hours prior to shipping and comes
with a lifetime warranty.

3.1 Power Hookup
The TTC-1000 can be powered from either DC substation battery between
voltages of 38 to 160 VDC or from AC voltage of 120 ±10% VAC. Power is
connected to terminals 1 and 2 on TB-3. The TTC-1000 is not sensitive to
polarity because it uses a bridge rectifier on the power input. This feature
eliminates the risk of damage due to the reversal of power applied to this input.

3.2 Temperature Probes
The TTC-1000 can be equipped with up to three probes. Universal thermowell
probe types TTC-PROBE-01 and TTC-PROBE-11 are each provided with three
thermometer well adapter fittings: 7/8-UNF (ANSI/IEEE C57 thermometer well),
½-NPT and ¾-NPT and three probe sleeves: 0.481, 0.625 and 0.675 OD.
Temperature probes are interchangeable and do not require calibration. The
temperature probes and measurement circuitry are intrinsically accurate to the
stated accuracy specification. The probe leads are connected to a pluggable
compression style terminal block. A terminal block is supplied with each unit and
plugs into TB2.
3.2.1 TTC-PROBE-01 Installation
Probe type TTC-PROBE-01 is provided with a strain relief that seals the
thermometer well and holds the probe from pulling out of the well. Figure 3.5
shows the outline drawing for this probe type.

3.2.3 Magnetic Mount Probe (TTC-PROBE-02) Installation
A magnetic mount probe (P/N: TTC-PROBE-02-xxx) is available for surface
mounting to the LTC or transformer tank when a thermo well is unavailable.
To mount the probe you will need:

RTV silicone sealant suitable for the outdoor applications and rated for the
maximum operating temperature.

Thermal grease (supplied with probe).
12
V5.204, March 11, 2008
To install the probe:
1. Coat center probe area with a liberal coating of thermal grease as shown in
Figure 3.7.
Apply a liberal coating of
Thermal Grease
Figure 3.7: Magnetic Mount, Application of Thermal Compound
2. Place probe on the wall of the transformer or LTC
tank to be monitored. The location should be as
high as possible on the tank, but bellow the top
level of the transformer’s or LTC tank’s oil level. It
is recommended that the probe be installed on the
LTC tank wall away from direct exposure to the
sun. Direct exposure of the tank to sunlight can
cause the surface to be at a slightly elevated
temperature above normal, which may cause the
differential temperature to be in error. See Figure
3.8.
Tank Wall
3. Place a bead of RTV silicone or other suitable
sealing compound around the perimeter of the
probe to seal the probe surface from moisture.
See Figure 3.9.

NOTE:
You must use all temperature probes for proper operation. The unit will
continuously alarm if you fail to use all probes.
If a probe is unavailable, you can use two 1,000 ohm resistors. One end of
one resistor to REF, the end of the second resistor to TMP. Tie the loose
end of both resistors to COM.
It is noted that probes can be supplied from lengths of 10 feet to 250 feet. When
using existing substation wiring with probe lengths less than 250 feet, it is
important to connect the probe’s shield drain wire to the shield the cable and
observe that the total wiring length does not exceed 250
feet. Also it is important to ensure that the TTC-1000’s
chassis is grounded to a point close to where the shield

3.4 Cooling Control and Condition Alarm Connections
Figure 3.14a illustrates the connections of the (4) form c dry relay contacts for
both NEMA and panel mount models. Figure 3.14 shows these connections on
NEMA 4 models, the contact arrangement for panel units is identical. Each relay
is capable of carrying 10 Amps at 230 VAC. Configure these contacts for cooling
control, high temperature alarms, or LTC condition alarm. Programming these
contacts will be discussed in Section 4.9.
16
V5.204, March 11, 2008
NOTE: The ability for these contacts to break its load is based on a number
of factors including voltage applied and the type of load. In general, there is
a higher tendency for contacts to become welded shut at higher voltages.
Therefore, protection devices, such as MOV’s are highly recommended if
these contacts will be required to break more load current than that shown
in the Specifications.

Unit Alarm Connections
The single form C relay is utilized to provide a dry contact closure for alarm
conditions. While the unit is energized, the alarm relay is energized. This allows
the unit to provide an alarm should the device lose DC power or becomes deenergized.
The TTC-1000 monitors five conditions: Processor (DEVICE), Temperature
(TPROBE), Winding (WNDG), Communications Processor (CPROC) and Manual
Mode (MANUAL). The TTC-1000 allows the user to enable or disable any or all
of the alarm conditions, except the Communications Processor alarm, through
programming. The user can also program how each output reacts when an
alarm occurs.
Figure 3.16 a&b illustrates the connections.
The user can program each output in how it reacts when either a Processor or
Temperature alarm occurs. The user can set an output to pick up, drop out, or
stay in its current state when either alarm occurs.

TTC-1000 provides a 9 pin female subminiature D connector on all models.
Panel mount models can either have analog outputs or an RS-485 interface for
DNP3.0 communications. NEMA 4 models can be equipped with both analog
interfaces and an RS-485 interface for DNP3.0 communications.
3.6.1 RS-232 Terminal Connections
Connection to this interface is through the front panel mounted DB-9 connector.
When connecting to a standard RS-232 port in a PC, either desktop or laptop,

3.6.2 Analog Outputs
The TTC-1000 is available with up to three analog outputs configured as current
loops. The source for each analog output can be selected from probe 1 (P1),
probe 2 (P2), probe 3 (P3), or calculated winding temperature. The analog output
is designed to operate with a series resistance of 9,500 Ohms when set to 0 to 1
mA or 450 Ohms when set to 4 to 20 mA.
NEMA 4 models equipped with a plug-in analog output module utilize TB5 for
connections to the analog outputs. The panel unit has TB5 on the back panel.
Connections to TB5 are shown in Figure 3.18. The terminal marked + is the
current source output. The connection marked – is the current transmitter’s return
and is tied directly to the chassis ground.

NOTE: Connect to the analog outputs through shielded cable. Connect the

The analog outputs A1, A2, and A3 can be programmed for 0 to 1 mA or 4 to 20
mA. All three analog outputs are identically programmed. Consult Section 5.4 or
6.3 for programming the scaling of the analog outputs.
3.6.3 RS-485 for DNP3.0 Communications
Units equipped with the optional DNP3.0 communications interface contain a
plug-in Communications Processor module with a two wire RS-485 interface. The
module contains a separate microprocessor to handle all overhead functions
associated with the DNP3.0 protocol without affecting operation of the
transformer cooling control and monitoring. The standard module contains a half
duplex RS-485 asynchronous communications interface capable of supporting
multi-drop topologies with a single shielded twisted pair cable. NEMA 4 models
can be optionally equipped with a four wire isolated RS-485 interface. RS-485
interfaces differ from RS-232 in that RS-485 uses a differential receiver and
transmitter pair. This permits RS-485 links to send and receive data over much
greater distances as long as some simple rules are followed.
Jumper J2 must be installed if the TTC-1000 is either the first or last device on
the multi-drop communications bus. Installation of the jumper connects a 120
ohm termination resistor. Termination is vital to reduce reflections which affect
proper operation when the length of the communications bus is long and/or there
are many devices connected. The two wire module uses a fail-safe RS-485
transceiver that insures that incorrect operation does not occur due to an open or
short circuit on the communications bus. While the TTC-1000 is immune from
shorted or open communications link, other devices may require the use of bias
resistors.
19
V5.204, March 11, 2008
The use of shielded twisted pair wire or cable is essential between nodes of the
communications bus. Connection of devices on the bus should be carefully
considered. Every device on the bus must be connected in a daisy chain fashion
like a string of Holiday lights. The devices on the bus should never be connected
in a star configuration. Polarity of the connections is also critical and should be
carefully observed and followed. For example, the “A” connection, also known as
the TD/RD should be connected to every other node’s “A” connection. Likewise
for the “B”, or the not TD/RD line. Figure 3.20 illustrates connections to the twowire interface.

For the panel configuration, there is no internal resistor. If a terminating resistor is
needed, it should be connected across the A and B terminals of the RS-485
connection on TB2.
There are many good references on implementing multi-drop RS-485
communication links from the semiconductor divisions of Texas Instruments,
National Semiconductor, and MAXIM Integrated Products.
3.6.4 Fiber Optic Interface for DNP3.0 Communications
Both panel and NEMA units can be equipped with the optional DNP3.0
communications interface using a plug-in Communications Processor module
with a multi-mode fiber optic interface. The module contains a separate
microprocessor to handle all overhead functions associated with the DNP3.0
protocol without affecting operation of the transformer cooling control and
monitoring. Fiber optics are recommended for substation installations as it avoids
the problems of ground potential rise issues commonly associated with direct
metallic connection.
20
V5.204, March 11, 2008
The optical interface operates at a wavelength of 850nm with 50 or 62.5 micron
multi-mode fiber terminated with ST style connectors. As with all fiber optic
communication links, the optical budget is an important number in determining
the maximum distance that can be spanned with a specific manufacturer’s fiber.
All optical fiber, whether it is glass or plastic core, has a specific loss in dB per
kilometer. It is important to remember that optical losses can vary from
manufacturer to manufacturer for the same core diameter and material. The
maximum distance which can be spanned is defined by the following equation:
DISTANCE in kM = (Optical Budget – 3dB) / Optical Loss in dB/kM
The optical budget for the TTC-1000’s optical interface is 9.1dB. Therefore, using
62.5 micron glass core fiber, with a loss of 4.0 dB / kM the maximum distance
spanned is approximately 1.5 kM or 4,900 feet.
The fiber optic interface has the ability to operate either point to point or can be
daisy chained with other intelligent electronic devices. A switch, S1, is provided
to allow the user to select either point-to-point or repeat. Setting S1 to REPEAT
passes the signal received on the fiber to the Tx fiber port without any delay.
In addition, three diagnostic indicators are provided for troubleshooting: Tx
indicates that the fiber interface is transmitting data to the DNP master, Rx
indicates that the fiber interface is receiving data from the DNP master, and ReTx if S1 is in the REPEAT position and received data is being re-transmitted
through the Tx port to the next IED in the chain.
Figure 3.22 is an outline drawing showing the fiber interface and the location of
switch S1 and diagnostic indicators Tx, Rx, and Re-Tx.

3.7 Optically Isolated Inputs
Models equipped with inputs contain two optically isolated inputs, IN1 and IN2.
These inputs must be wetted from an external power supply between 38 and 160
VDC. Connections are made through plug-in terminal block TB5. These optically
isolated inputs may be used by the programmable logic to control or supervise
any output. These inputs can also be used to communicate status information
from devices such as the liquid level alarm or sudden pressure over DNP3.0. IN1
and IN2 can be programmed to be LEVEL or PULSE active. Figure 3.22
illustrates these connections. The use of shielded cable is recommended.

NEMA 4X Models, TTC-1000-4XX, are equipped with a 13 Watt thermostatically
controlled heater and a specially designed vent that allows moisture to escape
and does not allow moisture to re-enter. The heater can be operated from DC
voltages of 38 to 160 or at 120 VAC. For convenience, the heater circuit is
connected to TB3 terminals 1 and 2. However, the user can connect the heater
to a separate power source.
The thermostat turns off the heater circuit when the internal ambient temperature
rises above 86 F (30 C) +/-10 F. The thermostat turns the heater back on at an
internal ambient temperature between 80 to 75 F.

4.3 Settings for Calculated Winding Temperature
Models equipped with the Aux CT input are supplied with a split core CT which is
snapped over the secondary leads from the bushing CT. You may skip this
section if your model does not contain this feature. The winding hot spot
temperature is calculated using the measured load current and top oil
temperature along with certain settings including the primary CT’s ratio, hot spot
rise over top oil temperature at rated load, rated load current, winding rise time
constant and if the transformer cooling is directed FOA or FOW.
The ranges for these settings are:
Setting
Setting Range
Comments
CT Ratio
1:1 to 9999:1
Can be set to 0
Hot Spot Rise over Top Oil
0 to 99  C
18 to 22  C
Rated Load Current
0 to 65,535 A
Enter top rating
Winding Rise Time Constant
0 to 999 minutes Minimum 32msec
m Constant
0.8 or 1
The steady state winding temperature is calculated based on the following
equation1:
TWindingU  TRTO  Load  CTRatio / RatedLoad 
2m
 TTopOil
[1]
Where:
TWindingU = Ultimate calculated winding temperature
TRTO = Hot Spot Rise over Top Oil temperature at rated load
Load = Measured load current
CTRatio = Primary CT ratio
Rated Load = Rated load current
m = 1.0 for directed FOA or FOW, 0.8 for all other cooling
TTopOil = Measured Top Oil temperature
It is noted that the Hot Spot Rise over Top Oil at rated load is not always
available. In this case we recommend using a value between 18 to 22 ºC.
To accommodate the transient affect of changing load current, the winding
temperature can be estimated at any point in time by entering the winding time
constant. Therefore, the displayed winding temperature is calculated as follows:
1
ANSI C57.91-1995
26
V5.204, March 11, 2008
TWinding (t )  (TWindingU  TWinding I )(1  e t / W )  TTopOil
[2]
Where:
TWinding(t) = Winding temperature at time t
TWindingU = Ultimate winding temperature using equation [1] above
TWindingI = Initial winding temperature using equation [1] above
W = Winding time constant in minutes
TTopOil = Measured Top Oil temperature
Because data to calculate  W may not be available, the recommended setting for
the winding time constant is between 5 to 10 minutes.
4.3.1 CT RATIO
The CT RATIO is the CT ratio of the bushing CT which the split core CT is
applied to. The CT ratio must be relative to 1. Therefore, if the CT ratio is 300:5
the CT ratio to enter is 60.
Programming from the front panel, press the
is displayed:
 arrow button until the setting 025
PRGM SETTING 025

digits. The currently active digit will flash. Press YES after you have entered all
four digits.
For programming from a PC just type the CT ratio on the “Enter:” line as follows:
Enter:104/60
4.3.2 Rated Load
The Rated Load setting is the top name plate rating in Amps. If the nameplate
indicates ratings of 1000/1200/1400, use 1400 as the rated load. On some
transformers the nameplate might only list the rating in MVA. In this case you will
need to divide the top MVA rating by the voltage of winding monitored with the
CT. The rated load for a 3 phase transformer is calculated as follows:
Rated Load = MVA / (Voltage x 1.732)
27

This will program the hot spot rise to 20 degrees Celsius.
4.3.4 Winding Rise Time Constant
The Winding Rise Time Constant is the amount of time, in minutes, for the
winding hot spot temperature to reach 67 percent of its final value. A number of
28
V5.204, March 11, 2008
factors including the volume and type of oil used and the mass of the transformer
are factors that influence this setting. Because calculating this value is
cumbersome, we recommend a setting from 5 to 10 minutes.

4.3.6 Checking Winding Temperature
A built in WNDGCAL test function is provided to verify proper operation of the
calculated winding temperature function. All settings described in Sections 4.3.1
through 4.3.5 must be made before performing this check. To verify correct
operation of calculated winding temperature:

Connect the split core CT to the unit as described in Section 3.3.

Loop a conductor from a suitable test set capable of generating 5.0 Amps
RMS through the window of the split core CT.

Press the  arrow button until the display reads:
WNDG TEMP AT 5A
WINDINGCAL = 45°c
Read the number where 45 appears above, record this number. This is the
computed value of the current top oil plus the rated rise of the transformer at
5 amperes of CT current.

Press
the
arrow
button
once.
The
display
will
read:
07/21/03 13:35
P1 TOPOIL 25C
Where the number in place of 25 is the current top oil temperature

Wait until the display scrolls to winding temperature:

Check the measured winding temperature against the WNDGCAL value. If
the winding temperature is not within three degrees, re-check the connections
to the split core CT and the current passing through the CT’s primary.
07/21/03 13:35
WINDING=45C
This feature compares the computed result for 5 amperes as compared to the
actual result of 5 amperes in the CT. The above assumes the rated rise was
20°C, the actual rise will be the rise entered as Rated Rise in 4.3.3 above.

from the TOP OIL, WINDING, BOTMOIL and AMBIENT temperatures.
Programming from the front panel, press the
is displayed:
 arrow button until the setting 096
PRGM SETTING 096
P1 NAME=TOP OIL
The same is true for settings 097 and 098 for the remaining two probes,
depending on how many probe channels were purchased
Press the YES button. The first character will flash. Use the  or arrow buttons
to scroll through the available names. Press YES after you have made your
selection.
When programming from a PC, the valid codes for the probe names available are
shown in the table above.
Therefore to display TOPOIL for probe 1, type:
Enter:109/0
In a similar manner, the remaining probes would be on program lines 110 and
111.
4.5 Temperature Set Points
The TTC-1000 has four independent temperature set points per temperature
probe and four calculated winding set points. Dual probe units with calculated
winding temperature have a total of 12 temperature set points. Each set point
has its own pick up and drop out temperatures. The pick up and drop out
temperature can be set at different temperatures and allows the controller to
31
V5.204, March 11, 2008
operate as either an under or over temperature controller. The following two
equations describe how the controller reacts depending on the setting of the pick
up and drop out temperature for liquid temperature probes:
If SPpn Pick UP > = SPpn Drop Out then operate as over temperature
If SPpn Pick UP < SPpn Drop Out then operate as under temperature
Where: p = Probe # (1, 2 or 3) & n = Set point # (1, 2, 3, 4)
The equation for winding temperature pickup and drop temperatures are:
If WSPn Pick UP > = WSPn Drop Out then operate as over temperature
If WSPn Pick UP < WSPn Drop Out then operate as under temperature
Where: n = Set point # (1, 2, 3, 4)
The over temperature set point is ideal for handling the pickup of fans or pumps,
as well as generating over temperature alarms and trip signals. The under
temperature feature is useful to block the operation of pumps at low
temperatures.
Figure 4.1 and 4.2 show when the SP picks up and drops out for when the
controller is configured to operate in the over and under temperature modes,
respectively.

Figure 4.2: Under Temp Operation
Once a set point has picked up, it will not drop out until the pre-programmed
conditions are met. This feature is especially useful to allow the fans to continue
to run until the top oil temperature drops to some lower temperature.
Each output can be controlled directly by a temperature set point. The flexible
programmable logic allows simple configuration to handle more complicated
tasks.
You will need to set pickup and drop out temperatures for each set point you
wish to use. Once set, temperature set points take up to 16 seconds to take
affect. Once you have established the pickup and drop out settings you are ready
to assign the set points to a specific output. A set point will not pickup an output
until you assign it to OUT1, OUT2, OUT3, OUT4, OUT5, or OUT6.
1. When changing pickup or drop out temperature set points, the new
value takes effect the next time temperature data is updated which
occurs every 16 seconds. However, once a SP is picked up, changing
the pickup temperature to a higher (if over temperature) or lower (if
under temperature) value will not cause the SP to drop out. Once a
temperature set point is picked up, the only way it can drop out is if the
drop out condition is met.
2. SP21, SP22, SP23, and SP24 drop out and pick up are settable in single
probe models, but do not have any function.
33
V5.204, March 11, 2008
3. WSP1, WSP2, WSP3, WSP4 drop out and pick up are settable in models
without the calculated winding feature, but do not have any function.
4.5.1 Setting Liquid Pickup and Drop Out Temperatures
These settings are used to start a stage of cooling or indicate a high temperature
alarm for probe 1, 2 or 3 liquid temperatures.
Since there are various configurations for the device, the use of the probe
outputs will depend on the features available and those used. The selection of
probe names will determine the way the programming uses the probe
information.
If a CT input has been included, winding temperature can be determined by the
CT current and the top oil temperature. It this way, the remaining probes can be
used for other tasks. If the CT option was not purchased, one probe will be
needed for use in the transformer’s heated well to measure winding temperature.
If the transformer has an LTC, use settings for LTC1, or LTC2, or both if there
are two tap changers. When a probe is designated as LTCDiff, LTCDiff1, or LTC
Diff 2, it is not available for other uses. The reported temperature from that probe
will vary between –20°C and +20°C depending on the relationship between top
oil and tap changer temperatures, as this is the arithmetic difference between
them limited to an overall 40°C range.
Any probe can be used for any function as long as the probe name is correctly
set as per the table in 4.4 above.
Assuming Probe1 is being used for temperature measurement the points are
programmed as follows. From the front panel, press the  or arrow buttons until
the setting 001 is displayed:
PRGM SETTING 001
SP11PICKUP= 60C

as follows:
Enter:25/85
This will program WSP1 pickup to 85C.
Enter:26/80
This will program WSP1 dropout to 80C.
4.6 Load Pickup Set Points
Load current is measured with an external split core Aux CT supplied with
models equipped with this feature. The Aux CT is not intended for direct
exposure to the elements and should be installed within a NEMA 4 enclosure.
Units equipped with this feature have two load set points. These two set points
can be applied to provide the Patented Load Pickup Cooling™ feature to activate
cooling earlier based on a sudden increase in load current due to normal
switching operations2. Each set point has a load pickup timer settable from 0 to
255 seconds. The timer operates to block inadvertent load set point pickup due
to fault conditions or inrush.
Each load set point has it’s own pickup and drop out current setting. Each setting
is adjustable from 0 to 9.9 Amps in 0.1 Amp increments. These settings are
based on the primary current measured by the split core CT. Figure 4.4 illustrates
the operation of the Load Pickup Set Points.

Figure 4.5: Load Pickup Set Point Operation
The first case shows that the load current remains above the pickup set point for
the full duration of the load pickup timer. In this case the load pickup set point will
be picked up. The second case shows a transient load or external fault wherein
the load current drops below the pickup point soon after the timer starts. This
causes the timer to reset and the load pickup set point remains dropped out.
NOTE: When load current is present, it is important to set the load dropout
set point before the load pickup set point. If load pickup set point is set
first, the load set point may be already picked up when this setting is made
and will not drop out.
The load set points can also be used to generate an alarm should the controller
command cooling and the cooling system is drawing too little or too much
current. For example, if the pickup current is set lower than the drop out current,
the set point operates as an under load detector. Conversely, setting the pickup
point higher than the dropout point allows the set point to operate as an overload
detector. Setting one set point for under load and the other as overload permits
detection of the cooling system’s load current “sweet spot”.
NOTE: The calculated winding temperature feature will not function
correctly when monitoring the cooling system’s load current.
4.6.1 Setting Load Pickup Set Point
These settings are used to start a stage of cooling based on a sudden increase
in load current. Two set points LSP1 and LSP2 are available to start up to two

configured to operate in under current mode. To operate in under current the
drop out current must be greater than the pick up current.

4.7 Optically Isolated Input Settings
The TTC-1000 may be optionally equipped with two optically isolated inputs.
Each input contains a limiting resistor that allows these inputs to recognize a
wide range of input voltage of 38 to 160 VDC as being picked up. Inputs are
scanned every 32 milliseconds. Contact chatter is debounced by requiring the
input be stable for two scans before the new state is recognized. Inputs may be
assigned to any output using the programmable logic.
Each of the digital inputs can be set either as level active, LEVEL MODE or
positive edge active, PULSE MODE. For LEVEL MODE, the recognized state of
IN1 or IN2 follows the voltage applied to the input. There is a built-in 64
millisecond debounce time on all low to high voltage transitions. There is no
debounce delay on high to low transitions. For PULSE, the recognized state of
the input toggles on every low to high voltage transition. High to Low transitions
will not change the recognized state of IN1 or IN2 in PULSE mode. There are
separate settings of LEVEL or PULSE for IN1 and IN2. Figure 4.6 illustrates the
operation of inputs set to LEVEL and Figure 4.7 illustrates the operation inputs
set to PULSE.

4.8 Programmable Logic Settings
The TTC-1000 utilizes a simple scheme to control the six relay outputs. Each
output can be configured to be picked up or dropped out by assigning any of the
available operands to a specific output. Table 4.7 illustrates the available
operands.

Table 4.8: Operands
An operand can only be assigned to a specific output and cannot be assigned to
another output as long as it is assigned. For example, SP11 cannot be assigned
to OUT2 and OUT3; it can only be assigned to either OUT2 or OUT3. IN1 or IN2
may be assigned like any other operand.
Any of the temperature set points or outputs can be inverted when assigned. For
example inverting SP11 will cause SP11 to be recognized as true whenever it is
de-asserted. Also, these specific operands can be either AND’ed () or OR’ed
(+) to a specific output. In evaluating a specific output, the TTC-1000 groups all
of the OR’ed terms together and all of the AND’ed terms together. As an
example by assigning SP11 + and SP21 + to OUT3 will result in the following
Boolean expression for OUT3:
OUT3 = SP11 + SP21
41
V5.204, March 11, 2008
Assigning SP11  to OUT3 and SP21  and SP12 + to OUT3 will result in the
following Boolean expression:
OUT3 = SP12  SP11SP21
Note, the OR operator plays no roll in the evaluation of the above expression.
The TIME operands cannot be inverted and can only be OR’ed to the other terms
assigned to the same output. As an example, if TIME2 is assigned to OUT3 in
addition to the operands SP1, SP2 and OUT1 as shown above, the Boolean
expression will be evaluated as:
OUT3 = (TIME2 + SP12)  SP11SP21
TIME set points are evaluated as true at any time the real time clock date is
within the specified pickup or drop out range of these set points.
NOTE: Do not use the inversion operator on individual set points when
remote control through DNP3.0 and fail-safe cooling control is desired. The
INVERT setting must be used on each output requiring fail-safe cooling
control when remote cooling control through DNP3.0 is required. The use
of the inversion operator on a set point will not be recognized by the
remote control functions resulting in the cooling to be de-energized.
There are additional settings available that enhance the flexibility of the
programmable logic. These functions include:

Output Timers for delaying pickup of the output relays.

Output Inversion that permits overall inversion of logic equations controlling
outputs. This is particularly useful for fail safe operation.
NOTE: Fail safe operation is strongly recommended. Fail safe operation
ensures that the cooling system picks up whenever the TTC-1000 becomes
de-energized or encounters a failure.
Fail safe requires the output relay controlling the cooling stage to drop out
instead of picking up. This requires that each of the individual terms
operating an output to drop out and be AND’ed to every term or each term
is OR’ed and the overall output invert used to drop out the relay. Please
remember to connect the contactor coil to the normally closed contact of
the TTC-1000’s output relay.
4.8.1 Assigning Liquid Temperature Set Points
Liquid temperature set points must be assigned to a specific output to start a
stage of cooling, generate high temperature alarms, and generate high
temperature trips. For more complicated applications, these set points can be
assigned to block a stage of cooling.

4.8.4 Assigning IN1 and IN2
The IN1 and IN2 can be incorporated into the programmable logic by assigning
these points to a specific output. IN1 and IN2 are useful if you wish to start a
stage of cooling through a switch on the control panel or even from your RTU. It
can also be used to block an output relay should the need arise. One such
application could be the blocking of a high temperature trip. To assign the IN1 or
IN2 to an output from the front panel, press the  or arrow buttons until the

The OUT1, OUT2, OUT3, OUT4, OUT5, & OUT6 can be incorporated into the
programmable logic by assigning these points to another output. This enhances
the ability of the programmable logic. It should be noted that an output should not
be assigned to itself unless a latching function is desired. To assign OUT1,

Consult the setting sheets to assign OUT2, OUT3, OUT4, OUT5, or OUT6.
4.8.6 Time Set Points
The time set points allow the user additional flexibility to activate events between
specific times. There are three time set points available.
Time set points are useful to exercise a bank of fans periodically. For example,
the user can set the device to pick up an output at 03:00 hours and drop out at
04:00 hours. Time set points can be used in conjunction with the temperature set
points to control an output. Therefore, when controlling a bank of fans for the
purpose of exercising them daily, it is necessary to OR (+) the temperature set
point to the same output as the time set point. Time set points are by default,
OR’ed to any other operand assigned to the same output.
A counter is provided to set the frequency at which the time set points will
operate. For example, setting the counter to 7 will operate the time set points
every 7th day.
Time set points use a 24 hour clock.
When using time set points in conjunction with temperature set points for the
purpose of picking up a cooling bank in fail-safe mode, both set points should be
assigned as usual. To operate in fail-safe, apply the OUT INVERT to the specific
output.

4.8.6.2 Time Set Point Counter Setting
The time set point counter sets the frequency at which the time set points will be
allowed to pick up. It is settable from 0 to 255. A setting of 0 or 1 will operate the
time set points on a daily basis.
Programming time set point counter from the front panel, press the

This will set all of the time set points programmed to pickup every 30th day.
4.8.7 Setting Output Timers
Setting the output timers delays the pickup of the output by the number of
seconds set. Each output has its own timer capable of being set from 0 to 255
seconds. A setting of 0 will permit the output to pickup as soon as all of the
programmable logic criteria are met. The output timer is only used in conjunction
with the programmable logic and has no effect in manual, remote or alarm
control.

This will set the delay to pickup output 1 by 15 seconds. Consult the setting
sheets to program the pickup timers for OUT2, OUT3, OUT4, OUT5, & OUT6.
4.8.8 Setting Output Invert
The output invert enhances the flexibility of the programmable logic by providing
an overall output inversion for an entire logic equation. This is particularly useful
for fail safe operation of the controller. Fail safe operation is highly recommended
as it allows your cooling system to be activated should the TTC-1000 become
de-energized or a device or temperature probe alarm is detected. Fail safe
operation is achieved by ensuring the output relay drops out when the necessary
set points are satisfied to command a stage of cooling. In fail safe it is vital to
remember to wire the contactor controlling the fan bank between the common
and normally closed contact.

INVERT OUT2, INVERT OUT3, and INVERT OUT4 can be selected by pressing
the  arrow button and following the above procedure.
For programming from a PC just type the setting for output invert on the “Enter:”
line as follows:
52
V5.204, March 11, 2008
Enter:98/1
This will set OUT1 to INVERT. Type 0 for OUT1 not INVERT.
Consult the setting sheets to change INVERT OUT2, INVERT OUT3, INVERT
OUT4, INVERT OUT 5, or INVERT OUT6.
4.8.9 Application Examples
Any of the operands (temperature set points, load set points, inputs, time set
points, LTCDIFF set points or the outputs themselves) can be assigned to OUT1,
OUT2, OUT3, OUT4, OUT5, OR OUT6. When assigning the temperature,
LTCDIFF, and output operands you have the option of inversion (!) and either
logically AND’ing (*) or OR’ing (+) the operand with other assigned operands to
control a specific output. For example, you can assign two temperature set points
with the AND (*) operator to OUT2. When both operands are picked up at the
same time, the OUT2 picks up, after a settable pickup timer has timed out. If the
OUT2 pickup timer is set to zero, OUT2 will pickup in 32 milliseconds once both
temperature set points are picked up. OUT2 will remain picked up until either of
the two temperature set points drop out.
Using the inversion operator with a temperature set point programmed for over
temperature, is particularly useful when it is desirable to run the fans if the
controller becomes de-energized. When using the inversion operator for this
purpose, it is necessary to use the B contact of the output relay.
Time set points are also operands that can be assigned to OUT1, OUT2, OUT3,
OUT4, OUT5 or OUT6. However, time set points do not use the inversion (!)
operator and are always assigned with the OR (+) operator.
An INVERT setting is available for each output to allow the entire equation to be
inverted. This is especially useful when using temperature and time set points
together in fail-safe.
NOTE: Do not use the inversion operator on individual set points when
remote control through DNP3.0 and fail-safe cooling control is desired. The
INVERT setting must be used on each output requiring fail-safe cooling
control when remote cooling control through DNP3.0 is required. The use
of the inversion operator on a set point will not be recognized by the
remote control functions resulting in the cooling to be de-energized.
The following are some applications examples:
4.8.9.1 Commanding the cooling fans:
The simplest application is using an output to control a cooling bank. First,
program the Pickup and Dropout temperature set point. Second, assign the set
point to an output as follows:
Using the LCD:
n=1,2,3,4,5,6
SPkl  OUTn where
kl=
53
11,12,13,14,21,22,23,24
and
V5.204, March 11, 2008
Using RS232:
kk/0/0/n
where k=Parameter # and n=1,2,3,4,5,6
The Boolean equation to control the same bank from two different set points is
expressed as follows:
OUTn = Temperature Set Pointkp1 + Temperature Set Pointk2l2
Using the LCD: SPkp1+ OUTn
where kp1=11,12,13,14,21,22,23,24 and n=1,2,3,4,5,6
SPkp2+ OUTn
where kp2=11,12,13,14,21,22,23,24 and n=1,2,3,4,5,5
Using RS232: kk1/0/1/n
where kk1=Parameter # and n=1,2,3,4,5,6
Kk2/0/1/n
where kk2=Parameter # and n=1,2,3,4,5,6
To control a bank in fail-safe, simply invert each setting as follows:
Using the LCD: !SPkl  OUTn
where kl= 11,12,13,14,21,22,23,24 and n=1,2,3,4,5,6
Using RS232: kk/1/0/n
where k=Parameter # and n=1,2,3,4,5,6
NOTE: Do not use the inversion operator on individual set points when
remote control through DNP3.0 and fail-safe cooling control is desired. The
INVERT setting must be used on each output requiring fail-safe cooling
control when remote cooling control through DNP3.0 is required. The use
of the inversion operator on a set point will not be recognized by the
remote control functions resulting in the cooling to be de-energized.
To control a bank using two set points in fail-safe:
Using the LCD:
SPkp1+ OUTn where kp1=11,12,13,14,21,22,23,24 and n=1,2,3,4,5,6
SPkp2+ OUTn where kp2=11,12,13,14,21,22,23,24 and n=1,2,3,4,5,6
Using RS232:
kk1/0/1/n where kk1=Parameter # and n=1,2,3,4,5,6
Kk2/0/1/n where kk2=Parameter # and n=1,2,3,4,5,6
Use the INVERT OUTn setting to cause the output relay to drop out when either
temperature set point is achieved. The resulting Boolean equation is:
OUTn = !(Temperature Set Pointkp1 + Temperature Set Pointkp2)
54
V5.204, March 11, 2008
4.8.9.2 Periodic exercise of cooling fans:
Use a time set point with the temperature set point, controlling the cooling fans,
to exercise the fans on a daily basis. This is especially useful in areas where you
might be running the fans continuously during the cooler months of the year. The
Boolean equation to accomplish this task is:
OUTn = Time Set Pointm + Temperature Set Pointkl
Therefore, the cooling fans will come on when either the over temperature
condition is achieved or the time of day is in between 02:00 to 03:00 hours.
To program the controller simply assign the time and temperature set points as
follows:
Using the LCD:
02:00 to 03:00 > OUTn
SPk + OUTn
Using RS232: mm/02:00/03:00/n where mm=parameter # and n=1,2,3,4,5,6
Kk/0/1/n
where k=parameter # and n=1,2,3,4,5,6
To operate the output in fail-safe, just invert the expression using the output
INVERT setting. Remember to use the B contact of the output relay.
4.8.9.3 Cooling Fan Alarm:
This example shows how to generate an alarm when cooling is commanded but
the measured current as sensed by the Aux CT is not within a specified range.
The Boolean equation for this function is expressed as:
OUTn1 = (Load Set Pointm1 + Load Set Pointm2)  OUTn2
First you must program Load Set Pointm1 for an underload condition, that is the
pickup current less than dropout, and Load Set Pointm2 for overload. Once these
are programmed the two load set points must be assigned as OR to OUTn1 as
follows:
Using the LCD:
LSPm1+ OUTn1 where m1=1,2 and n1=1,2,3,4,5,6
LSPm2+ OUTn1 where m2=1,2 and n1=1,2,3,4,5,6
Using RS232:
mm1/0/1/n1
where mm1=Parameter # and n1=1,2,3,4,5,6
mm2/0/1/n1
where mm2=Parameter # and n1=1,2,3,4,5,6
Then assign the output, OUTn2, commanding cooling to OUTn1 as follows:
Using the LCD:
OUTn2  OUTn1
Using RS232:
n1/0/0/n2
where n1=1,2,3,4 and n2=1,2,3,4,5,6
where n1=Parameter # and n2=1,2,3,4,5,6

V5.204, March 11, 2008
4.9 Setting Output Control With Alarm
The TTC-1000 monitors two critical conditions: processor (DEVICE) and
temperature (TPROBE) and allows the user to control how each output reacts
when an alarm occurs. A DEVICE alarm occurs anytime the microprocessor
detects a failure in any of the peripheral hardware including the non-volatile E2
memory, the real time clock, analog outputs, corruption of stored data and power
supply brown out.
The TPROBE alarm is generated anytime the processor is unable to obtain
reliable temperature information. This failure can be due to a discontinuity in the
leads connected to the temperature probe or with any of the internal circuitry
associated with the analog to digital conversion process. All temperature set
point evaluations are suspended until the alarm condition is cleared.
The TTC-1000 allows you to program how an output will react whenever there is
a DEVICE or TPROBE alarm. There are three (3) ways an output can react
whenever there is a DEVICE or TPROBE alarm:
1. Unchanged (UNCHG): the output remains as it was prior to the
alarm.
2. Picked Up (PCKUP): the output picks up when alarm occurs.
3. Supervised (SUPVS): the output drops out when alarm occurs.
The TTC-1000 output control default is UNCHG for each output.
The user should decide how they wish each output to operate whenever there is
either a DEVICE or TPROBE alarm. For example if OUT1 and OUT2 control two
separate banks of fans, it might be desirable to have OUT1 and OUT2 pickup as
soon as a DEVICE or TPROBE alarm occur. This insures that the fans are
running even though there might be a device or temperature probe failure.
NOTE: It is strongly recommended to set output control to supervised
(SUPVS) for all outputs controlling cooling fans in fail-safe mode.
However, if OUT3 is used for a trip signal, it may be desirable to use the DEVICE
or TPROBE alarm to supervise OUT3. This will insure that a trip signal is blocked
whenever a DEVICE or TPROBE alarms occur.
Also, if OUT4 is used for a high temperature alarm, it may be desirable for OUT4
to remain unchanged if a DEVICE or TPROBE alarm occurs. This will insure that
a high temperature alarm continues to be reported.

This will set OUT1 supervised with a Device or Temperature Probe Alarm. Type
1 to pickup OUT1 with a Device or Temperature Probe Alarm, or 0 to leave the
output unchanged with a Device or Temperature Probe Alarm.
Consult the setting sheets to change output control for OUT2, OUT3, OUT4,
OUT5 OR OUT6.
4.10 Alternate Fan Banks
The TTC-1000 can be programmed to alternate the energization between two
outputs. This feature is particularly useful when it is desirable to insure a fan
bank is regularly exercised.
You can choose between seven (7) alternate options:
1. Disabled (DSABL)
2. Alternate between OUT1 and OUT2 (1 – 2)
3. Alternate between OUT1 and OUT3 (1 – 3)
4. Alternate between OUT1 and OUT4 (1 – 4)
5. Alternate between OUT2 and OUT3 (2 – 3)
6. Alternate between OUT2 and OUT4 (2 – 4)
7. Alternate between OUT3 and OUT4 (3 – 4)
As an example, if Alternate between OUT1 and OUT4 is selected, the first time
OUT1 picks up, the output relay associated with OUT1 will pick up. If OUT4 picks
up while OUT1 is picked up, the relay associated with OUT4 will pick up.
Once both OUT1 and OUT4 drop out, the next time OUT1 picks up the relay
associated with OUT4 will pick up. If at sometime in the future OUT4 picks up
when OUT1 is already picked up, the relay associated with OUT1 will pick up.
The cycle repeats when both OUT1 and OUT4 have dropped out.

ALTERNATE=1-4, 4 to ALTERNATE=2-3, 5 to ALTERNATE=2-4, or 6 to
ALTERNATE=3-4. Type 0 to disable alternate.
NOTE: Outputs 5 and 6 cannot be set to alternate .
4.11 Auto and Manual Control
The TTC-1000 supports direct manual control of any output relay directly from
the front panel. When commanded ON, the relay picks up and commanded OFF
the relay drops out. Manual control is important for two reasons. First, it gives the
user a simple method to test the connections to the output relays when
commissioning the unit. Second, it gives the user the ability to manually override
both automatic or remote control should the operator desire to command cooling
on a continuous basis. It can also be used to prevent an output from picking up.
Manual mode can be exerted by communicating through the RS-232 interface,
but it is impossible to control the output relay using this method. This setting
should only be used when it is desired to block remote control of a specific output
relay. Also, the TTC-1000 will leave the output relay in whatever state it
happened to be at the time manual control is exerted through the RS-232
interface.
The TTC-1000 will cause the Device Alarm contacts to pick up when an output is
put into the manual mode. In addition the ALARM LED on the front panel will
illuminate. The user can block this alarm by using the manual mode alarm
disable setting shown in Section 4.13.
58
V5.204, March 11, 2008
Once in Manual Mode any output relay will be de-energized if power is removed
upon re-energization. The output remains in Manual Mode and cannot be reenergized without physically going to the device and turning the output on in the
manual mode.

Setting outputs from AUTO to MANUAL from a PC will only allow the output to be
dropped out. It is not possible to pickup an output when setting from a PC. To
change from AUTO to MANUAL using a PC just type the setting for auto or
manual on the “Enter:” line as follows:
Enter:48/1
This will set OUT1 to MANUAL OFF. Type 0 to return OUT1 to AUTO.
Consult the setting sheets to change AUTO to MANUAL for OUT2, OUT3, and
OUT4, OUT5 AND OUT6.
4.12 Setting Control of Unit Alarm
The single form B relay is utilized to provide a dry contact closure for alarm
conditions. While the unit is energized, the alarm relay is energized. This allows
the unit to provide an alarm should the device lose DC power or becomes deenergized.
The TTC-1000 monitors five conditions: Processor (DEVICE), Temperature
(TPROBE), Manual Mode (MANUAL), Winding (WNDCKT), DNP3.0
Communications (CPROC). The TTC-1000 allows the user to enable or disable
all of the alarm conditions, except the DNP3.0 Communications (CPROC),
through programming.

Interrupt and it keeps track of the time, date and day of the week. Also, the time,
date, and day are maintained even while the unit is unpowered for 5 days at
85ºC. The TTC-1000 powers the RTC through the use of large value that
eliminates the need for battery backup and is designed to operate over the entire
temperature range.
Time and date are used to evaluate the TIME set points and data logging.

LTC MONITORING AND PROTECTION
5.1 LTC Condition Monitoring
The TTC-1000 has up to three set points that the user can employ for LTC
conditioning monitoring. The LTC differential, or LTCDIFF, is the mathematical
difference between the LTC tank and top oil temperatures and therefore is only
available in dual temperature probe units. The range of the LTCDIFF is from –20
to +20 ºC. The three set points are defined in the following table.
Probe
Name
Timer
Function
Set Points
LTCDIFF
None
The temperature output for
this probe will be the
arithmetic difference
between the probe and Top
oil limited by +20°C and 20°C Output is
instantaneous
The 4 setpoints associated
with the probe, for P2, the
setpoints would be SP21,
22, 23, and 24. These can
be assigned to Outputs as
needed
LTCDIFF1 LTCPUTMR1 The temperature output for
this probe will be the
arithmetic difference
between the probe and Top
oil limited by +20°C and 20°C. A pick up of
LTCDIFF1 starts timer
LTCPUTMR1 and the point
picks up with the timeout of
the timer.
LTCDIFF1 is assigned to
the desired output relay.
LTCDIFF2 LTCPUTMR2 The temperature output for
this probe will be the
arithmetic difference
between the probe and Top
oil limited by +20°C and 20°C. A pick up of
LTCDIFF2 starts timer
LTCPUTMR2 and the point
picks up with the timeout of
the timer.
LTCDIFF2 is assigned to
the desired output relay.
Each of the three take one dedicated probe to implement, and that probe cannot
be used for any other function. Therefore, care must be taken to be sure there
are enough probe channels to accomplish the desired functions. For instance, if
P1 is used for Top Oil, P2 for Ambient, a third probe would need to be available
66
V5.204, March 11, 2008
for LTC monitoring – and this for only one tap changer. Should the transformer
have two tap changers, only one probe would be available for other functions
such as Top Oil.
NOTE: When using LTC condition monitoring, it is important to remember
to name one of the probes LTCDIFF, LTCDIF1 or LTCDIF2. Evaluation of the
LTC set point is not done unless one of the probes is named for that
function (LTCDIFF, LTCDIFF1, or LTCDIFF2).
Figure 5.1 illustrates how the LTC differential set point operates for LTC condition
monitoring.

Figure 5.1: LTC Differential Set Point Operation
The TTC-1000 uses an LTC pickup timer settable from zero to 999 minutes to
supervise the LTC set point. The above example shows that the LTCDIFF1 & 2
set points do not pickup until after the timer is complete. If the differential
temperature drops down below the pick up temperature while the timer is in
progress, the timer will reset. This timer allows the LTCDIFF1 & 2 set points to
“ride” through daylight heating and hence permits a more sensitive setting. The
above example shows that the LTC set point does not drop out because the
difference between the LTC Tank temperature and the Top Oil temperature does
not drop below the LTCDIFF1 or 2 drop out temperature set point.
67
V5.204, March 11, 2008
NOTE: The LTCDIFF and LTCDIFF1 & 2 temperature displayed is the
calculated differential. The corresponding analog output tracks this
differential temperature.
All LTCDIFF temperature set points are designed to read negative as well as
positive. The reason for this is that sometimes the LTC tank runs cooler than the
top oil temperature. It is recommended that you monitor the LTCDIFF
temperature for a period of time to determine the normal operating differential for
the transformer. A good rule of thumb is to set the LTCDIFF pickup temperature
from 3 to 7 degrees higher than the observed operating differential. For
LTCDIFF1 & 2, the sensitivity of this setting can be improved through the use of
the LTC pickup timers (LTCPUTMR1 & 2) settings. The recommended setting for
the LTCPUTMR is between 360 to 480 minutes ( 6 to 8 hours ), to ignore the
affects of daylight heating on a lightly loaded transformer. The LTCPUTMR can
be set up to 999 minutes ( 16 hours 39 minutes ).
To use this feature you must first make sure one of the probes has been named
LTCDIFF(1 or 2). Next, program the LTCDIFF(1 or 2) PU (pickup) and
LTCDIFF(1 or 2) DO (drop out) temperatures. As mentioned earlier, it is a
recommended that the LTCDIFF temperature be monitored to determine the
transformer’s normal operating point. For LTCDIFF(1 or 2), the appropriate
LTCPUTMR can be set once the transformer’s normal operating condition is
determined. Setting the LTCPUTMR to zero permits the associated LTCDIFF set
point to pickup as soon as the LTCDIFF PU temperature is reached (essentially
the same function as LTCDIFF). Setting the LTCPUTMR(1 or 2) to some time
other than zero will delay the pickup of the LTCDIFF(1 or 2) set point as long as
the LTCDIFF1 or 2 temperature is equal to or above the LTCDIFF(1 or 2) PU
temperature.
NOTE: The LTCPUTMR will not change while in progress. New settings will
take effect after the set point drops out or if the LTCDIFF temperature were
to drop below the LTCDIFF PU temperature while the timer is in progress.
Once you have established the pickup and drop out settings you are ready to
assign the LTC set point to a specific output. This set point will not pickup an
output until you assign it to OUT1, OUT2, OUT3, or OUT4.

NOTE:
1. In single probe versions, all LTCDIFF pickup and dropout settings
display “N/A”.
2. Be careful to check that the LTCDIFF & LTCDIFF1 & 2 pickup and
dropout set points are never set to greater than 20 or less than –20.
Erroneous operation of the LTCDIFF pickup or dropout will result if
these set points are set beyond the stated range.

Figure 5.2: LTCDIFF Rate of Rise Method
The LTCDIFF Rate of Rise method uses two parameters: LTCDIFF RISE and
LTCDIFF RATE. This function is disabled if either of these parameters are set to
zero. This method operates by comparing the measured rise between a start and
stop period defined by parameter LTCDIFF RATE with the programmed
parameter LTCDIFF RISE. If the measured rise is greater than or equal to the
LTCDIFF RISE an internal set point LTCDIFF R-R is picked up. The
recommended range for setting LTCDIFF Rise is 5 to 20 C LTCDIFF Rate can
be set from 1 to 255 minutes.
NOTE: The rate of rise feature will remain picked up unless the unit is powered
down to reset it. If this has picked up, there is an extremely serious problem in
the tap changer and immediate attention is required.

TELEMETRY OPTIONS
This section will discuss the various telemetry options available, their use and
any relevant settings. The TTC-1000 can be optionally equipped with current
loop outputs and a RS-485 DNP3.0 communications interface. All TTC-1000’s
come equipped with a 9 pin DB-9 connector for RS-232 ASCII communications.
Temperature information can be retrieved through the RS-232 interface.
6.1 Analog Outputs
The TTC-1000 is available with up to three analog outputs configured as current
loops. The source for each analog output can be selected from probe 1 (P1),
probe 2 (P2), probe 3 (P3), or calculated winding temperature. The analog output
is designed to operate with a series resistance of 9,500 Ohms when set to 0 to 1
mA or 450 Ohms when set to 4 to 20 mA. The third analog output is configured to
supply 0 to 1 mA and cannot be switched to operate in the range of 4-20 mA.
NEMA units with serial letter suffix ‘B’ contain TB4 for connections to the analog
outputs. All other NEMA units utilize TB2. The terminal marked + is the current
source output. The connection marked – is the current transmitter’s return and is
tied directly to the chassis ground.
NOTE: Connect to the analog outputs through shielded cable. Connect the
drain wire of the shield to one of the ground studs inside the NEMA 4
enclosure. Twisted pair cable is recommended.
The analog outputs A1 and A2 can be programmed for 0 to 1 mA or 4 to 20 mA.
Both analog outputs are identically programmed.
The scaling of the analog output varies depending on what is being measured.
The following table illustrates the scaling dependent on range and the quantity
measured and whether negative temperature scaling is enabled:
Probe

0 to 1 mA Range:
4 to 20 mA Range:
Upon initialization, the DAC is set to zero, if 0 to 1 mA or offset to drive 4 mA, if
set for 4 to 20 mA. During the initialization process, the processor looks to see if
the DAC is installed. If installed, the DAC will be updated every 16 seconds when
new temperature data is available.
74
V5.204, March 11, 2008
Should the user select a new range, the output will not change range until new
temperature data is available.
The relationship of the analog output differs depending on what the probe is
measuring. For top oil, winding, and ambient temperatures the relationship
between output current and temperature is as follows:
Range 0 to 1mA with normal scaling:
For measurements from P1 or P2: Current = Temperature/160
For calculated winding temperature:Current = Temperature/180
Range 4 to 20mA with normal scaling:
For measurements from P1 or P2: Current = 0.1 x Temperature +4
For calculated winding temperature:Current = 0.089 x Temperature + 4
Range 0 to 1mA with negative scaling:
For measurements from P1 or P2: Current = Temperature/195
For calculated winding temperature:Current = Temperature/215
Range 4 to 20mA with negative scaling:
For measurements from P1 or P2:
Current = 0.08205 x Temperature +6.872
For calculated winding temperature:
Current = 0.07442 x Temperature + 6.605
For LTCDIFF the relationship is as follows:
Range 0 to 1mA:
Current  Temperature  40  0.5
Range 4 to 20mA:
Current  0.4  Temperature  12
6.1.1 Setting the Analog Output Range
The analog output range for both A1 and A2 can be switched from 0 – 1 mA to 4
– 20 mA. The range of the third analog output is fixed at 0 – 1 mA and cannot be
changed. To change this setting, enter PROGRAM mode from the front panel as
discussed in Section 4.1.
To set the analog output range from the front panel, press the or arrow button
until the setting 099 is displayed:
PRGM SETTING 099
ANALGOUT=0to1mA
75
V5.204, March 11, 2008

For programming from a PC, enter PROGRAM through the main menu as
discussed in Section 4.2. Once in PROGRAM, type the setting for the
ANALGOUT range on the “Enter:” line as follows:
Enter:113/1
This will change the analog output range from 0 – 1 mA to 4 – 20 mA. Type 0 to
change to 0 – 1 mA.
6.1.2 Setting the Analog Source
The source of data for the analog input can either be liquid probe P1, liquid probe
P2, or calculated winding temperature. The TTC-1000 automatically scales the
data to be reported.
To change this setting, enter PROGRAM mode from the front panel as discussed
in Section 4.1. To set the analog source from the front panel, press the or
arrow button until the setting 100 displayed:
PRGM SETTING 100

Press the YES button. The first character will flash. Use the
to scroll between P1, P2 and WINDING.
 or arrow buttons
PRGM SETTING 100
A1SOURCE>P1
Press YES when you have made the correct selection. A2 source can be
selected by pressing the  arrow button and following the above procedure. The
setting for A3 source will appear if installed.
76
V5.204, March 11, 2008
For programming from a PC, enter PROGRAM through the main menu as
discussed in Section 4.2. Once in PROGRAM, type the setting for the A1
SOURCE on the “Enter:” line as follows:
Enter:114/3
This will change the source for analog output A1 to WINDING. Type 0 to change
the source to P1 or 1 to change the source to P2 or 2 to change the source to
P3.
6.1.3 Enabling Negative Scaling
The default scaling of analog outputs for all but LTCDIFF is from zero degrees.
However, if operating in cold climates, it may be necessary to scale the analog
outputs from –35 ºC for all temperatures except LTCDIFF.
To change this setting, enter PROGRAM mode from the front panel as discussed
in Section 4.1. To set the analog source from the front panel, press the or
arrow button until the setting 128 is displayed:
PRGM SETTING 128
NEG ANALGOUT=NO
Press the YES button. The first character will flash. Use the
to scroll between YES and NO.
 or arrow buttons
Press YES when you have made the correct selection.
For programming from a PC, enter PROGRAM through the main menu as
discussed in Section 4.2. Once in PROGRAM, type the setting for the NEG
ANALGOUT SCALING on the “Enter:” line as follows:
Enter:134/1
This will change the scaling from normal to negative. Type 0 to change back to
normal scaling.
6.2 DNP3.0
Units equipped with the optional DNP3.0 communications interface contain a
plug-in Communications Processor module. The module contains a separate
microprocessor to handle all overhead functions associated with the DNP3.0
protocol without affecting operation of the transformer cooling control and
monitoring. The module contains either a half duplex, full duplex isolated RS-485,
multi-mode fiber optic asynchronous communications interface capable of
supporting multi-drop topologies. RS-485 interfaces differ from RS-232 in that
RS-485 uses a differential receiver and transmitter pair. This permits RS-485
77
V5.204, March 11, 2008
links to send and receive data over much greater distances as long as some
simple rules are followed. See Sections 3.6.3 and 3.6.4 for connections and
jumper settings.
After making the proper connections to the TTC-1000, there are only two settings
that need to be made: Node Address and Baud Rate. Node Addresses can be
any number from 0 to 65535. Please consult the DNP3.0 reference materials as
some higher order addresses are reserved for broadcast messages.
Baud Rates can be set to either 1200, 2400, 9600 or 19200. It is recommended
that both Node Address and Baud Rate settings be made before attempting to
communicate, however these settings can be changed “on-the-fly” without
powering down the TTC-1000.
The TTC-1000 implements DNP3.0 Level 1 communications. This includes Class
0 polls (Object 60 Variation 1) of analog and binary output points. The TTC-1000
supports Object 1 Variation 2 binary outputs. Binary outputs include all
temperature and load set points along with the state of each output relay.
Because Variation 2 is supported, the TTC-1000 communicates whether or not
an output relay is under manual control by exerting the “forced” status bit for
these points only. The “forced” status bit is located in bit 4 of each binary output
octet transmitted to the Master. For Analog Outputs, the TTC-1000 supports
Object 30 Variation 4. These are 16 bit signed analog quantities without status.
Included in the Analog Output points are all temperatures equipped plus load
data if available. Also, the TTC-1000 uses two points to identify whether or not
the probe is measuring Top Oil, Heated Well, LTC Differential or Ambient
temperature. This is particularly useful for dual probe units. It is noted that Object
1 Variation 2 and Object 30 Variation 4 points cannot be read individually and
can only be read by a Class 0 poll.
In addition, the TTC-1000 supports the remote control of the four output relays.
The TTC-1000 supports both direct control (Object 10 Variation 0) and Select
Before Operate control (Object 12 Variation 1). The TTC-1000 permits the user
to command an output relay to pickup. It cannot be used to dropout an output
relay. If the Binary Input point is turned off, it merely returns the device to local
automatic control. Once the unit accepts the remote control command, the
“remote forced” bit will become a logic “1”. The “remote forced” bit will remain a
logic “1” until that point is dropped out by the DNP Master.
Remote control can be blocked through the use of the REMOTE BLK setting.
Enabling this setting will prevent all output points from picking up through remote
control. Also, enabling the REMOTE BLK setting after an output has been
commanded to remotely pickup but before remote control is returned to local
control, will cause all output points to revert back to local automatic control. The
“remote forced” bit will remain logic “1” until the point is returned back to local
automatic control. Remote control will be immediately re-enabled once the
REMOTE BLK setting is disabled.
In addition, local manual control overrides remote control. The user should
observe the status of the “local forced” bit in the appropriate Binary Output point,
as noted above, before attempting to exert control as the TTC-1000 will
78
V5.204, March 11, 2008
remember that the bit has been exerted even though the TTC-1000 is in Manual
Mode. Once an output is released from Manual Mode, the output will either
return to automatic or remote control. If the point had been commanded
remotely, the output will pickup as soon as the field personnel remove local
manual control. This could result in an undesired operation of the specific output
relay. User’s of remote control should always remember to turn off a Binary Input
once they have turned it on to insure a return to local automatic control. This is
why Users should observe the “local forced” and “remote forced” bits.
To maintain compatibility with Fail-Safe operation of the cooling system, remote
commanding of cooling operates in conjunction with the INVERT setting for each
output. For example, if the INVERT bit is set for OUT1, then the OUT1 relay will
drop out. This is an important point to remember when setting the programmable
logic as Fail-Safe cooling will not be observed under remote control if the user
implements Fail-Safe cooling by assigning a set point using the inversion
operator.
Finally, the user should not expect instantaneous report of updated temperature
and status from the TTC-1000. The use of a separate Communications
Processor does not guarantee instantaneous reporting of data. The philosophy of
implementation is that the top priority of the Main microprocessor is for control
and monitoring and the Communications Processor is to receive potentially highspeed request messages from the DNP Master and to respond to these requests
without delay. While higher polling rates are possible, it is highly recommended
that the polling rate be between 1,000 to 10,000 milliseconds, but should be no
faster than 500 milliseconds.
Please refer to the DNP3.0 Profile Document in Section 15 for additional details
and specific definitions of all points supported.
6.2.1 Setting BAUD Rate

discussed in Section 4.2. Once in PROGRAM, type the setting for the node
address on the “Enter:” line as follows:
Enter:118/7
This will set the node address to 7.
6.2.3 Setting Remote Blocking
Remote block is useful if it is necessary to block remote control of any of the
output relays. This is only necessary if Objects 10 and 12 have been
implemented to permit Supervisory and Control to command cooling remotely.
80
V5.204, March 11, 2008
To change this setting, enter PROGRAM mode from the front panel as discussed

For programming from a PC, enter PROGRAM through the main menu as
discussed in Section 4.2. Once in PROGRAM, type the setting for remote block
on the “Enter:” line as follows:
Enter:119/1
This will enable remote block. Type 0 to disable remote block.
6.3 Telemetry Via RS232
Asynchronous data communications is implemented through the front panel
mounted DB-9 connector at a fixed data rate of 9600 bits per second, 8 bits of
data, no parity, and one stop bit. We have verified operation of the interface with
Procomm Plus, HyperTerminal and Windows Terminal 3.1. It is recommended
that the terminal emulation be set for either ANSI or TTY. The pin out of this port
is designed to use a 9 pin female to 9 pin male null modem cable.
The TTC-1000 permits remote reporting of temperature or resetting of the time of
day by sending a forward slash ‘/’ followed by either the characters T
(temperature) or R (reset) followed by an ASCII carriage return character (13
Hex).
Sending the string: /T
causes the TTC-1000 to reply with the ambient
temperature. The temperature reported will be in the units (Celsius or Fahrenheit)
that the TTC-1000 was programmed to display temperature. Units are not
transmitted. It is noted that the command /T is echoed back to the host computer
along with the measured temperature without a carriage return character. For
example, if the TTC-1000 is measuring an ambient temperature of 68 ºF, the
exact format of the reply for a single probe unit is:
81
V5.204, March 11, 2008
68
For dual probe versions, the reply is:
68/93
Where the first temperature is probe #1 and the second is probe #2.
Sending the string /S causes the TTC-1000 to report the status of the output
relays (OUT1, OUT2, OUT3 OUT4, OUT5 and OUT6) and alarm type (DEVICE,
TPROBE, and WDGCKT) as a series of ASCII character ‘0’ for off and ASCII
character ‘1’ for on. The string reported is as follows:
OUT1/OUT2/OUT3/OUT4/ALRM_DEVICE/ALRM_TPROBE/ALRM_WNDCKT
A typical response to the /S command is:
1/0/0/0/0/0/0/0/0
This string indicates that OUT1 is picked up and OUT2, OUT3, OUT4, OUT5,
OUT6, ALRM_TPROBE, ALRM_TPROBE, and ALRM_WNDCKT are dropped
out.
Sending the string /R causes the TTC-1000 to reset the real time clock to
00:00:00 hours. The date is not changed. It is noted that the characters /R are
echoed back to the host computer.

The temperature & time display will be the first display you see upon power up.
Date, time, and temperature are updated when fresh data is available. The
display will continuously scroll through a set sequence. The sequence will
depend on the number of liquid temperature probe channels and if the unit is
equipped to measure calculated winding temperature. Automatic scrolling can be
interrupted at any time by pressing the YES button. Once automatic scrolling is
stopped, pressing the  or arrow buttons will permit manual scrolling to the
various displays. To resume automatic scrolling, press the NO button.

10 SETTING FILES
Uploading and downloading of setting files can only be accomplished through
connection from a PC directly connected to the TTC-1000. To save a setting file
on your PC use Upload Setting file. To transfer a previously stored setting file
from your PC to the TTC-1000, use Download Setting file.
10.1 Upload Setting Files
Upload settings transfers the binary settings to a designated file in a PC
connected through the RS232 communications port. The TTC-1000 uses the
XMODEM protocol which is supported by HyperTerminal, HyperAccess, as well
as other terminal emulation programs. Checksum error checking is employed.
10.1.1 Upload Settings Using HyperTerminal
HyperTerminal as supplied in Windows XP does not work properly when scrolling
back to view settings and is not recommended. It is recommended to use
HyperTerminal Private Edition for interfacing with the TTC-1000. The following
instructions apply to both versions. In these instructions, HyperTerminal will
stand for both versions, XP and Private Edition.
The procedure to upload a setting file is as follows:
1. Press Enter to display the TTC-1000 Main Menu.
2. Press 4 and then press Enter:
3. Click on Transfer on the HyperTerminal toolbar, a drop down menu will
appear –
a. Click on Receive File and a dialog box will open
b. Select Xmodem from the Use Receiving Protocol option
c. Click on the Browse button and another dialog box will open where
the directory can be selected to place the file.
d. Click on Receive
4. Another dialog box will open for entering the file name the file is to be
saved as.
a. Enter the file name and click on OK The three letter suffix will not
automatically be added. It is a good practice to add an ending such
as .BIN or .DAT to indicate it is not a text file. .
5. Another dialog box will open that shows the file transfer progress
a. HyperTerminal will try twice with CRC error detection to transfer the
file. The third attempt will be using Checksum, the method the TTC1000 uses.
b. The retry box will briefly show 3 and then the box will disappear.
This means the file has been saved.
c. If the number of retries exceeds 3, cancel and start over. At this
94
V5.204, March 11, 2008
point the transfer will not take place. Recheck your settings.
d. If the main TTC-1000 menu returns to the HyperTerminal window,
the transfer has timed out and the procedure must be restarted.
6. Even if the HyperTerminal transfer times out, continue with the procedure
up until the transfer progress dialog box appears. This will save your
settings as far as protocol and directory so that it will not need to be reentered, thus speeding up the process and avoiding another timeout.
NOTE: Upload can be terminated by pressing the Esc key on your PC prior
to starting the file transfer.
10.1.2 Upload Settings Using HyperAccess
The procedure to upload a setting file is as follows:
1. Press Enter to display the TTC-1000 Main Menu.
2. Press 4 and then press Enter:
3. Click on Transfer on the HyperAccess toolbar, a drop down menu will
appear –
a. Click on Receive File and a dialog box will open
b. Click on the Browse button and another dialog box will open where
the directory can be selected to place the file.
c. Select Xmodem from the Transfer Protocol option
i. Click on the Settings button
ii. A dialog box will open where you can select the Error
Checking mode
iii. Select Checksum (This setting can be left in Auto, but the
program will try twice with CRC until it tries Checksum)
d. Click on Receive
4. Another dialog box will open for entering the file name the file is to be
saved as.
a. Enter the file name and click on OK. The three letter suffix will not
automatically be added. It is a good practice to add an ending such
as .BIN or .DAT to indicate it is not a text file.
5. Another dialog box will open that shows the file transfer progress. If the
main TTC-1000 menu returns to the HyperAccess window, the transfer
has timed out and the procedure must be restarted.
6. Even if the HyperAccess transfer times out, continue with the procedure
up until the transfer progress dialog box appears. This will save your
settings as far as protocol and directory so that it will not need to be reentered, thus speeding up the process and avoiding another timeout.

V5.204, March 11, 2008
10.2 Download Setting Files
Download settings transfers the binary setting file on your PC to the TTC-1000
connected through the RS232 communications port. The TTC-1000 uses the
XMODEM protocol which is supported by HyperTerminal and HyperAccess as
well as other terminal emulation programs. Checksum error checking is
employed.
NOTE: Be careful that the file sent is NOT a text file and is a valid settings
file. Transferring a text version of a settings file into the TTC-1000 will
cause the settings to be overwritten by text characters causing
unpredictable behavior. To recover from this situation, download a known
good settings file to overwrite the text. The master password 0905 will need
to be used to regain access. Should this not work, please contact us for
assistance.
NOTE: Download may be terminated prior to the transfer by pressing any
key on the keyboard
NOTE: The TTC-1000 will suspend all measurements and calculations once
downloading is selected. The outputs will also be blocked during this time.
The TTC-1000 transfers the new settings to a buffer register and will
transfer the settings to E2 memory only after the checksum test is passed.
10.2.1 Download Settings Using HyperTerminal
The procedure to download a setting file is as follows:
1. Press Enter to display the TTC-1000 Main Menu
2. Type 5 followed by / followed by the 4 digit password:
a. Note that at any time the internal data in the unit is to be changed,
the password will need to be entered.

11 DATA LOGGING
Data logging permits storage of time stamped temperature and load data. The
user has the ability to change the time base used for time stamping from 1 to
9999 seconds. Setting the time base to zero erases the log and prevents records
from being recorded. The user can select which points to record. Points which
can be recorded include probe P1’s temperature, P2’s temperature, calculated
winding temperature, and load. Once the log is full, the oldest records are over
written with the newest records. Since the records are stored in non-volatile
memory, records are never lost even in the event of a power interruption.
11.1 Data Storage
There are 32,512 bytes available for storage of data records. A byte is defined as
an 8 bit quantity. Each record is time stamped at an interval defined as the Time
Base. A data record is defined as a set of data points. Data points can include
probe P1’s temperature, P2’s temperature, P3’s temperature, calculated winding
temperature, and load. All temperatures are stored as a single byte. Load is
stored as a two byte quantity. There are two additional bytes per record to assist
the firmware in storing and retrieving the data log. A record can be anywhere
from 3 bytes to 8 bytes in length. The following table summarizes the available
data points and the maximum number of records that can be stored:
Points Recorded
Bytes/Record
Max Records
P1, P2, P3 or Calculated Winding

10,837
Any two temperatures

6
5,418
All three temperatures and Load
7
4,644
All three temperatures, Winding and Load
8
4,064
Table 10. 1: Maximum Records
After selecting the data points to log, it is simple to figure out the length of time
data can be recorded. For example if 30 minutes time stamping is required, Time
Base=1800, and all four points (P1, P2, Winding & Load) are required, the
maximum time that data can be recorded in days is equal to 4,644 divided by 48
records per day or 96 days. This can be extended to up to 1254 days if only one
temperature is recorded every 9999 seconds or ~2.75 hours. Practically
speaking, a temperature and load will be logged every hour or 3600 seconds. In
this case the log will hold 270 days of data.
There is one limitation, in the event that power is interrupted, the time stamp is
stored as a data record. Time stamp records consume a total of 8 bytes. This is a
98
V5.204, March 11, 2008
non-factor if power is never interrupted, but if the device is AC powered, it could
reduce the number of records by a small amount.
11.2 Data Points
Data recorded can be selected for logging. For P1, P2, or P3, the data recorded
takes the name chosen for the specific temperature probe. If P1 or P2 or P3 is
chosen as LTCDIFF, the data recorded is the differential between the LTC tank
temperature and the Top Oil probe. All other temperature points are recorded as
the absolute value of the measured temperature.
The load current reported is the average or demand logged for the period
between samples. If a Time Base of 15 minutes is selected, the load current is
the average value over 15 minutes. For Time Base settings less than 16
seconds, the load current reported will be the actual load current.
11.3 Setting the Time Base
Time Base can be entered from 0 to 9999 seconds. Setting the Time Base to
zero will reset the log and no records will be logged. Changing the Time Base will
erase the log and commence recording with the new Time Base.
To change this setting, enter PROGRAM mode from the front panel as discussed
in Section 4.1. To set the time base from the front panel, press the or  arrow
button until the setting 106 is displayed:
PRGM SETTING 106
TIMEBASE=0000sec
Press the YES button. The first digit will flash. Use the

or
arrow buttons to
scroll through the digits 0 – 9. Use the  or buttons to scroll between the
digits. The currently active digit will flash. Press YES after you have entered all
four digits.
For programming from a PC, enter PROGRAM through the main menu as
discussed in Section 4.2. Once in PROGRAM, type the setting for the time base
on the “Enter:” line as follows:
Enter:120/3600
This will set the Time Base to 3600 seconds.
11.4 Selecting Data Points
Any or all of the data points can be selected for logging. Change the number of
points or the points recorded will erase the log. If no points are selected the log
will be erased and no data logged. There are five points that can be added to the
log: P1, P2, P3, Calculated Winding, and Load. The heading names for probes
P1, P2, and P3 in the data log will be as displayed on the front panel.
