1. INTRODUCTION

1.1 GENERAL
The Feeder Protection System (FPS) is a modular
system with integrated protection, control, metering, and
data-logging functions. The Control Unit (FPS-CTU) is
the core module. It can operate as a stand-alone unit or
with the Operator Interface (FPS-OPI), and an
RTD Module (MPS-RTD). The CTU can be programmed
using the OPI or the communications network.
Programmable inputs and outputs provide a flexible
hardware platform and custom software can be easily
loaded from a PC to the CTU’s flash memory. The FPS
block diagram is shown in Fig. 1.1.

Introduction
FPS Feeder Protection System

Rev. 1-C-031615
2. INSTALLATION
2.1 GENERAL
A basic Feeder Protection System (FPS) consists of an
FPS-CTU and three customer-supplied current
transformers (CT's) for measuring phase current. For
core-balance earth-fault detection, a 1-A, 5-A, EFCT-1, or
EFCT-2 CT is required.
The residual phase-CT
connection can also be used for earth-fault detection.
Voltage inputs do not require potential transformers
(PT’s) for system voltages up to 600 Vac. For RTDtemperature measurement an MPS-RTD module can be
connected to the FPS-CTU. The FPS-OPI provides an
operator interface for the FPS.
The FPS power-factor corrected switch-mode power
supply is rated 65 to 265 Vac and 80 to 275 Vdc.
All modules can be mounted in any orientation.
2.2 FPS-CTU CONTROL UNIT
The Control Unit is configured for surface mounting.
Outline and mounting details for the FPS-CTU are
shown in Fig. 2.1.
2.3 FPS-OPI OPERATOR INTERFACE
Outline and mounting details for the FPS-OPI are
shown in Fig. 2.2. It is certified for use in Class I, Zone 2
and Class I, Division 2 hazardous locations.
The Operator Interface is configured for panel
mounting or it can be mounted on the FPS-CTU as shown
in Fig. 2.3.
2.4 MPS-RTD RTD MODULE

3. SYSTEM WIRING
3.1 GENERAL
A typical connection diagram is shown in Fig. 3.1. The
FPS-CTU provides the 24-Vdc supply for the peripheral
modules and it communicates with them using an RS-485
interface. The total length of the I/O communication
system must be less than 1.2 km (4,000’). The power
supply in the FPS-CTU will not support more than three
I/O modules. An external 24-Vdc power supply is
required if more than three modules are used.
The FPS-CTU voltage inputs can be directly connected
to a system with line-to-line voltages up to 600 Vac. PT's
are required for system voltages higher than 600 Vac.
Input resistance of the voltage inputs is 3.4 M.
NOTE: The current and voltage inputs must be phase
sequenced A-B-C with correct polarity observed.
Breaker or contactor OPEN and CLOSE commands
can be issued through the digital inputs, the network
interface, or the FPS-OPI. Breaker or contactor control
and interlock contacts can be wired to any of the
programmable digital inputs. The five programmable
output relays can be used for control, protection, and
interlock functions. Relay 5 is a solid-state, low-level
output relay not recommended for breaker control. See
Section 9 for relay ratings.
Page 3-1
Rev. 1-C-031615
3.2.1.2 CURRENT INPUTS
The FPS-CTU uses 1-A or 5-A CT’s for phase-current
measurement. To maintain specified accuracy, phase
CT’s should be selected with a primary rating between
100 and 300% of feeder current rating. Current threshold
is 1.5% of CT-primary rating.
All CT inputs can withstand a common-mode voltage
of 120 Vac so that the FPS-CTU can be connected in
series with other CT loads. The connection diagram in
Fig. 3.1 shows a typical connection where the FPS-CTU
is the only device connected to the phase CT's. The
FPS-CTU requires the phase sequence to be A-B-C with
correct polarity.
A 1-A, 5-A, or sensitive CT is used for core-balance
earth-leakage measurement.
3.2.1.3 VOLTAGE INPUTS
For all input-voltage connections, the FPS-CTU
requires the phase sequence to be A-B-C with correct
polarity.
If voltage inputs are not used, connect VA, VB, and
VC to VN.
NOTE: A voltage input is required for line-frequency
metering.
NOTE: The default configuration has no assignments for
digital inputs and relay outputs.
3.2 WIRING CONNECTIONS
3.2.1 FPS-CTU CONNECTIONS
The FPS-CTU CT-input terminal blocks accept 22 to
10 AWG (0.3 to 4.0 mm2) conductors. The remaining
FPS-CTU clamping blocks accept 24 to 12 AWG
(0.2 to 2.5 mm2) conductors. Terminal blocks unplug to
allow the FPS-CTU to be easily replaced.
3.2.1.1 SUPPLY VOLTAGE
Connect supply voltage to terminals 1 and 2 (L1 and
L2) as shown in Fig. 3.1. In 120-Vac systems, L2 is
usually designated as the neutral conductor. For directcurrent power supplies, use L1 for the positive terminal
and L2 as the negative terminal. Earth terminal 3 ( ).
Internal surge-protection devices are connected to
terminals 4 (SPG) and 4A (SPGA) to allow dielectricstrength testing. Terminals 4 and 4A must be connected
except during dielectric-strength testing.
The 24-Vdc I/O module supply (terminals 56 and 60)
can support three I/O modules. An external 24-Vdc
supply is required if more than three modules are used.

3.2.1.4 DIGITAL INPUTS
Digital inputs 1 to 8 (terminals 44 to 51) are referenced
to COM (terminal 43). These inputs are isolated from all
other terminals and operate over a 24 to 130 Vac/Vdc
range. Inputs 1 to 7 have programmable functions. See
Table 4.2.
System Wiring
Page 3-4
Rev. 1-C-031615
FPS Feeder Protection System
3.2.1.4.1 DC OPERATION
Supply voltage for dc-input operation can be obtained
from the 24-Vdc source (terminals 41 and 42), or it can be
obtained from an external 24- to 130-Vdc supply.
The internal source is current limited at 100 mA and is
referenced to the analog output (terminal 40) and the I/O
Supply (terminal 56). Connect the “” terminal of the dc
source to COM and connect field inputs between “+” and
the digital-input terminals.
3.2.1.4.2 AC OPERATION
Inputs operate over a 24- to 130-Vac range. Connect
the ac neutral to COM and connect field inputs between
line and the digital inputs.
3.2.1.4.3 COMBINED AC AND DC OPERATION
If both ac and dc inputs are used, connect both the acsupply neutral and dc-supply “” to COM.
3.2.1.5 ANALOG INPUT (AN IN)
The analog input (terminal 52 and 53) is a 4–20-mA
current input with a 100- input impedance.
NOTE: The analog input is referenced to an internal
supply with 100-k resistors. Maximum common-mode
voltage is ± 5 Vdc with respect to FPS-CTU terminal 4.
3.2.1.6 ANALOG OUTPUT (AN OUT)
The analog output is a self-powered current-source
output. The current-source output is the “+” (terminal 39)
and the common is “” (terminal 40).
NOTE: The analog output (terminal 40) is internally
referenced to the 24-Vdc source (terminal 42) and the I/O
supply (terminal 56).
3.2.1.7 PTC INPUT
Terminals 54 and 55 are provided for PTC overtemperature protection. See Section 9 for specifications.
3.2.1.8 IRIG-B INPUT
Terminals 61 and 62 are used for an IRIG-B time-code
signal. When an IRIG-B signal is detected, the real-time
clock (RTC) synchronizes with it. The user must set the
FPS date value because the IRIG-B day-of-the-year
parameter is not supported.
If the time-code generator does not have a local-time
adjustment, the IRIG Offset set points can be used to
adjust the hour and minute values so that the FPS will
read local time.
3.2.1.9 I/O MODULE COMMUNICATION
The I/O module communications interface (terminals
56 through 60) is used to support optional modules. The
connector labeled Operator Interface on the FPS-CTU top
panel is in parallel with terminals 50 to 56. It is used for
direct FPS-OPI mounting. See Section 2.3.
I/O module communication is based on the two-wire
multi-drop RS-485 standard. Overall line length must not
exceed 1.2 km (4,000’). For line lengths exceeding
10 m (33’), 150- terminations are required at the cable
ends. See Fig. 3.7.
3.2.1.10 RS-485 NETWORK COMMUNICATIONS
Terminals 35, 36, and 37 are used for the standard
RS-485 interface. See Section 4.2.15.
3.2.2 FPS-OPI CONNECTIONS AND ADDRESS SELECTION
Connect the FPS-OPI to the FPS-CTU using shielded
cable (Belden 3124A or equivalent). The 24-Vdc supply
for the FPS-OPI is provided by the FPS-CTU. The cable
shield must be connected at both ends so that
FPS-OPI transient protection is operational. See Fig. 3.7.
The FPS-OPI has two switches to select its network
address. See Figs. 2.2 and 3.6. Up to three FPS-OPI
modules can be connected to the I/O MODULE bus, and
each active OPI must have a unique address. If one OPI
is used, address 1 must be used. If two OPI’s are used,
addresses 1 and 2 must be used. If three OPI’s are used,
addresses 1, 2, and 3 must be used.
Table 3.1 and Fig. 3.6 shows the addressing selection

4.1 GENERAL
The FPS-CTU can operate independently. It can also
operate in conjunction with network communications, the
FPS-OPI, and the MPS-RTD. All settings are stored in
the FPS-CTU and can be accessed using the OPI or the
network communications interface. Use SE-Comm-RIS
software and an SE-485PP or SE-485-DIN serial converter
to program with a personal computer.
In the following sections, menu items and setup
parameters are listed in italics and are shown in the format
displayed on the OPI. The OPI cannot display subscripts
and superscripts.
Menu selection is in the following format:

Each digital input can be assigned to one of the
functions listed in Table 4.2. More than one digital input
can be assigned the same function.
Close inputs are not active when Protection Only is
selected as the control type. OPEN on the FPS-OPI is
always active. When Control Type is set to None, OPEN
initiates a Trip1 signal.
Close Bypass, Bypass Delay, and Trip Delay set points
apply only when Trip1 is selected. When Close Bypass is
enabled, the Trip1 function is bypassed when a close is
detected for the duration specified by Bypass Delay.
After the Bypass Delay, the Trip1 function is enabled and
a trip occurs if the digital-input voltage is removed for the
time specified by the Trip Delay. If Close Bypass is
disabled, Bypass Delay is not used and the Trip1 function
is always enabled.
Reset inputs are “one-shot” resets that require a
transition from open to closed. Maintaining a reset switch
closure does not inhibit trips.
LOCAL is selected using the digital input, or by
network communications. The Local Select source is
responsible for de-selecting. For example if both the
digital input and the network communications select
LOCAL, both must also de-select LOCAL. In the event
that the network fails to deselect LOCAL, de-selection
can be performed using the Setup  System Config 

The following rules apply when multiple inputs are
assigned the same function:
 3-Wire Close and 3-Wire Close Local: Momentary
voltage on any input will initiate a close. (FPS must
be in LOCAL for Local Close operation.)
 Permissive: Voltage must be present on all inputs to
allow an FPS-controlled close.
 Interlock: Voltage must be present on all inputs to
allow an FPS-controlled close and to energize an
interlock output relay. Digital inputs programmed as
Interlock are bypassed in LOCAL.
 52a Close Status: Voltage must be present on all
inputs when device is closed and not present when
device is open.
 Reset: Voltage applied to any input will reset trips.
 2-Wire Close: Voltage on any input will initiate a
close. All inputs must be removed for valid open.
 52b Open Status: Voltage must be present when
device open and not present when device is closed.
Operation and Setup
Page 4-4
Rev. 1-C-031615
FPS Feeder Protection System
The Permissive and Interlock settings are used in
conjunction with the breaker or contactor control
functions. Both must be valid to allow a close operation.
The permissive input is typically connected to a normally
closed push-button when 3-wire control is used. The
distinguishing feature between permissive and interlock
inputs is that interlocks are bypassed in LOCAL while
permissive inputs must be valid for both REMOTE and
LOCAL modes of operation.
Device open and close status is monitored by inputs
programmed as 52a Close Status and 52b Open Status.
The 52a inputs must be valid (voltage present) when the
device is closed and the 52b inputs must be valid (voltage
present) when the device is open. See Section 6.2.1.
For maximum control integrity and immunity to power
fluctuations, the 24-Vdc source voltage provided on
terminals 41 and 42 should be used for digital-input
operation. If external ac voltage is used for digital-input
control, it is recommended to connect control voltage to
one of the digital inputs programmed for Control Power.
This input is used to indicate the presence of control
voltage. When voltage is not detected on this input, a
500 ms delay is active on all other inputs to allow the FPS
to “ride-through” voltage fluctuations and power-off
conditions without a false trip caused by loss of voltage
on a digital input.
4.2.10 ANALOG OUTPUT

4.3 FPS-OPI
4.3.1 GENERAL
See Fig. 4.2. The Operator Interface (OPI) is used to
perform control functions, display meter readings, and
program the FPS-CTU. Set points are not resident in the
OPI. Control voltage for the FPS-OPI (24 Vdc) is
supplied by the CTU and communications with the CTU
is through an RS-485 link. This allows the FPS-OPI to be
mounted up to 1.2 km (4,000’) from the CTU. Up to
three OPI’s can be used with each CTU.
4.3.2 CONFIGURING THE FPS-CTU FOR OPI
OPERATION
OPI Menu: Setup | Hardware | OPI Display
Select the number of OPI's in the Number of OPI’s
menu. The FPS-CTU supports up to three OPI’s. In
multiple-OPI systems, all OPI’s display the same
information and the CTU will process key presses from
all OPI’s. If an OPI is not used, set number of OPI’s to 1
(default).
A loss-of-communication trip can be enabled in the
OPI-Loss Trip menu. Display intensity can be set in the
Intensity menu.
To extend the life of the vacuum-florescent display, a
screen saver is provided and enabled using the Screen
Saver menu. The screen saver activation time is defined
by the Setup | System Config | Password Timeout setting.
4.3.3 BREAKER CONTROL
OPI Menu: Setup | Control | Control Select Type
A control type other than Protection Only must be
selected for breaker control functions to become
operational.
Breaker control operates in one of two modes;
REMOTE or LOCAL. REMOTE mode is the default.
LOCAL mode is selected using one of the digital inputs,
see Table 4.2, or a network command. The OPI
REMOTE or LOCAL LED’s indicate the control mode.
4.3.3.1 LOCAL CONTROL
OPI Menu: Setup | Digital Inputs | Digital Input x |

4.4 MPS-RTD
OPI Menu: Setup | Hardware | RTD Modules
OPI Menu: Setup | Protection | RTD Temperature
The MPS-RTD module extends FPS protective
functions to include multiple-RTD temperature
monitoring. It has eight inputs that can be individually
configured for RTD type, trip and alarm settings, name,
and function. The RTD types are 10- copper, 100-
nickel, 120- nickel, and 100- platinum. Three
function assemblies (A1, A2, A3) are available.
Minimum and maximum temperatures are available for
each assembly and for ambient temperature.
Control voltage for the MPS-RTD (24 Vdc) is
supplied by the FPS-CTU and communication is through
an RS-485 link. This allows the MPS-RTD to be
mounted up to1.2 km (4,000’) from the FPS-CTU.
To enable RTD protection, select enable in the RTD
Module menu.
When the hardware has been configured, temperature
set points and sensor-failure action selections in the RTD
Temperature menu are used for RTD temperature
protection. See Section 5.22.

5. PROTECTIVE FUNCTIONS
5.1 GENERAL
The FPS measures true RMS, peak, and fundamentalfrequency values of current and voltage. Fundamentalfrequency values (magnitude and phase angle) are
obtained using Discrete-Fourier Transform (DFT)
filtering that rejects dc and harmonics. The type of
measurement used for a protective function is indicated in
each section.
Each protective function can be assigned a trip action
that defines the output contact(s) used. Except for
overload protection which has auto-reset available, FPS
trips are latched. Trips are logged, alarm actions are not.

and CT-input protection elements can be enabled
simultaneously to provide low- and high-level earth-fault
protection in solidly grounded systems.
Phase-overcurrent and earth-fault protection functions
have two setting groups; Group 1 and Group 2. Set points
are entered for each group and the active group is selected
using the menu system, communications, or a digital
input. See Section 4.2.9. Group selection allows setting
two levels of protection. This is useful in feeder
applications where the connected load changes as in tiebreaker systems, or in applications where the feeder is in
maintenance mode and operation with reduced trip levels
is required. Reduced current settings allows meeting
NEC 240.87 Arc Energy Reduction (B) (3) Energyreducing maintenance switching with local status
indicator.
SE-Comm-RIS PC-interface software can be used to
plot FPS protection curves. See Section 8.1.2.
NOTE: See Appendix B for default set-point values.
Per-unit notation (pu) is used. 1 pu = 100%.
5.2 OVERLOAD
5.2.1 I2t PROTECTION
Menu: Setup | Protection | Overload
Unlike IEC and IEEE inverse-time overcurrent
protection, the I2t protection tracks thermal capacity for
currents below the pickup setting.
The I2t protection algorithm uses the square of the
maximum phase current as an input.
The cold-curve time-to-trip (t) in seconds for currents
above the I2t Pickup setting is defined by:
2
t = 60 × τ × ln
⎛ IM
⎜
⎜I 2–1
⎝ M
⎞
⎟
⎟
⎠
Where:
τ = Time Constant setting in minutes
To operate output contacts, trip and alarm actions must
be assigned to output relays using the Setup  Relay
Outputs menu. See Section 4.2.8.
For phase-overcurrent protection, three protection
elements are availableoverload, inverse time, and
definite time. Each can be enabled or disabled as required
and are individually annunciated.
IEC and IEEE inverse-time curves are supported. An
IEC time multiplier setting range of 0.05 to 1.0 is
provided. For consistency, the same multiplier is used for
IEEE curves. For equations and curves see Figs. 5.1 to
5.9 in Section 5.3.
For earth-fault protection, inverse time and definitetime elements are available for the calculated zerosequence component (3I0). For the earth-fault CT inputs,
only definite-time protection is provided. Calculated (3I0)
IM =
IMeasured
IPickup
The time constant for overload protection is set in the
Setup  Protection  Overload  Groupx  Time Constant
menu. This value is specified in minutes.
From a given curve, the time constant can be determined
by knowing the trip time at six times the pickup value (t6).
For this case, the time constant simplifies to:
τ = 0.591 × t6
Where:
T6 = Time in seconds at 6 × pickup level
τ = Time Constant setting in minutes
Protective Functions
Page 5-2
Rev. 1-C-031615
FPS Feeder Protection System
The FPS provides indication of thermal trend and used
thermal capacity. Thermal trend is the value that used
thermal capacity is tending toward and it is a function of
the square of load current. For currents greater than or
equal to the pickup current, time-to-trip is displayed in
Metering | Thermal Capacity. The thermal trend value
(Trend I2t) in percent is:
Trend I 2t  IM 2  100%
For currents less than I2t Pickup current, Trend I2t in
percent is a function of the Hot Factor setting given by:
Trend I 2t  IM 2  HF  100%
Where :
HF  Hot Factor setting
Selected I2t overload cold curves are shown in Fig. 5.1.
FPS I2t overload protection is dynamic. Time to trip at
any overload current depends on the value of
Used I2tas Used I2t increases, time to trip decreases.
The FPS I2t overload cold and warm protection curves
can be plotted using SE-Comm-RIS PC-interface
software.
An overload trip occurs when Used I2t reaches 100%.
When an overload trip occurs, reset is not allowed until
Used I2t falls below the I2t Reset Level set point. The
time-to-reset in minutes is:
t = -  Cooling Factor  ln(I2t Reset Level)
Time-to-reset is displayed in Metering | Thermal
Capacity.
The thermal model has three different reset modes;
Normal, Auto, and Rapid. The I2t-overload reset mode is
set using the Setup  Protection  Overload  I2t Reset
Type menu, and applies to both set-point groups.
A thermal-overload trip reset is not allowed until Used
I2t falls below the I2t Reset Level setting. In Normal mode
a reset input is required to reset a trip. Normal is the
default reset mode.
In Auto mode, an I2t-overload trip is automatically reset
when Used I2t falls below the I2t Reset Level setting.
In Rapid mode, Used I2t decreases exponentially with a
fixed two-second time constant when current is not
detected. A reset input is required to reset a trip.

Emergency Thermal Reset (ETR) sets Used I2t to 0%
and disables PTC and RTD temperature trips. Password
entry is required. Disabled-temperature protection is
indicated by t Disabled by ETR in the System State
display. If PTC or RTD temperature protection is not
enabled, t Disabled by ETR will not be displayed. RTD
or PTC trips are reset when ETR is performed regardless
of measured temperatures. Temperature protection must
be re-enabled in the Messages  Emerg I2t Reset 
Reenable Temp menu, or by cycling supply voltage.
Temperature alarms and sensor verification remain
enabled during ETR.
CAUTION: Temperature protection is not automatically
re-enabled after an Emergency Thermal Reset.

NOTE:
The FPS time-multiplier setting of 1.0
corresponds to the IAC/CO “time-dial” setting of 15.
The Curve menu is used to select one of the curve
shapes listed in Table 5.1. Pickup is in per unit of
phase-CT rating and specifies the location of the curve’s
vertical asymptote (IM = IDFT/Ipickup = 1). Time Multiplier
selects the specific curve within the curve type.
The FPS uses the same time-multiplier range of 0.05 to
1.0 for both IEC and IEEE curves.
For each curve, treset defines the time to reset after a trip
has occurred (IM = 0)
The Metering  Inverse Status menu indicates whether
current is above or below Pickup.

Menu: Setup | Protection | Ph Def Time
The definite-time overcurrent function has both trip and
alarm settings. With the DFT measurement method it
may be possible to set the overcurrent protection closer to
the desired value as compared to an RMS measurement
method.
The asymmetrical-current multipliers for RMS and
DFT measuring methods are shown in Fig. 5.10. Typical
X/R values are 6.6 for a low-voltage system, 15 for a
medium-voltage system, and can be as high as 25 for a
high-voltage system. The DFT filters the dc component
so that the overcurrent setting can be set closer to the
symmetrical fault value.

5.9 PHASE LOSSCURRENT
Menu: Setup | Protection | Phase Loss (I)
Phase loss is a severe form of unbalance and can be
used to detect open-circuit faults. When phase loss occurs
on a three-phase load, negative-sequence current (I2) is
equal to positive-sequence current (I1). The phase-loss
algorithm considers I2/I1 from 0.90 to 1.00 to be a phase
loss. Set the phase-loss trip delay shorter than the
unbalance trip delay to avoid an unbalance trip in the
event of a phase loss.
The phase-loss threshold is fixed at 10% of the
CT-primary rating (Ip).

5.8 CURRENT UNBALANCE
Menu: Setup | Protection | Unbalance (I)
Menu: Setup | System Config | I2/I1 Threshold
Positive-sequence current (I1) and negative-sequence
current (I2) are used to determine current unbalance (I2/I1).
The unbalance display range is 0.00 to 1.00 where 1.00 is
100% unbalance—a single-phase condition. Single-phase
loads generate unbalance that may cause false trips when
feeder currents are low. The I2/I1 Threshold sets the
current level where unbalance protection becomes active.
The threshold is based on the maximum of the threephase currents. Set this value above the single-phase load
value to avoid false trips. Negative unbalance is indicated
when current inputs are connected B-A-C (negativesequence current is greater than positive-sequence
current). Severe unbalance may also be indicated if
phase-CT polarity is incorrect.
5.10 PHASE REVERSECURRENT
Menu: Setup | Protection | Phase Rev (I)
If the current phase sequence is B-A-C, the magnitude
of negative-sequence current will be larger than the
magnitude of positive-sequence current. To maintain
magnitude consistency for set points, the I2/I1 ratio is
inverted for the protection algorithm when phase
sequence is B-A-C. A negative unbalance is indicated in
the meter display for B-A-C sequence.
The phase-reverse threshold is fixed at 10% of the
CT-primary rating (Ip).

Phase loss is a severe form of unbalance. When phase
loss occurs, negative-sequence voltage (V2) is equal to
positive-sequence voltage (V1) and voltage unbalance is
100% or 1.00 pu. The phase-loss algorithm considers
V2/V1 from 0.90 to 1.00 to be a phase loss. Set the phaseloss trip delay lower than the unbalance trip delay to
avoid an unbalance trip in the event of a phase loss.

From the OPI Control Type menu, select a control type
or select Protection Only.
When Protection Only is selected, all control functions
except OPEN are disabled and all OPI control-select

Trip1 when the FPS is in Protection Only.
CAUTION: When Protection Only is selected, OPEN will
not function if Trip1 is not assigned to a relay output.
NOTE: When control functions are used, protective
functions will open operate the CB Open output to open
the breaker or contactor when a trip occurs. Reset is
required.

The FPS can operate in one of two control modes,

using network communication, or a digital input. In each
of the control selections, the Close Source can be selected
as shown in Table 6.1.
When a control type is selected, control can be
performed with the digital inputs, OPI, or network
communications.
See Section 4.3.3 for details on
selecting breaker-control sources.
The digital inputs allow concurrent operation of two
control methods; three-wire open/close and two-wire
open/close. Three-wire control requires two digital
inputs, one programmed for 3-Wire Close (N.O.
momentary switch) and one programmed for Permissive
(N.C. momentary switch) as shown in Fig. 6.1. Two-wire
control uses one input, programmed as 2-Wire Close, for
open/close control and can be used where a single contact
provides open/close operation. See Fig. 6.2. If close was
activated by a two-wire input, any other OPEN will
initiate a latching Trip1 as well as operating the CB Open
output. In all other cases, OPEN does not cause a trip.

inputs or interlocks may not generate a trip or alarm
condition but may prevent a close operation. The
Messages | Status Messages menu will display a digitalinput identifier and related message indicating what is
preventing the close operation.
Select a control type of None for applications in which
a manually operated, electrically tripped device such as a
shunt-trip or under-voltage breaker is used. No breaker or
contactor open/close control is used and the shunt or
under-voltage coil must be connected to an output relay
assigned to Trip1, Trip2, or Trip3. The output relay
assignments associated with breaker or contactor control
(CB Open, CB Close, Contactor) are disabled when the
control type is set to None. The REMOTE and LOCAL
LED’s are off with this selection.
For shunt-trip breakers, use a normally open output
contact and set the relay mode to Non-Fail-Safe. For
undervoltage breakers, use a normally open output contact
and set the relay mode to Fail-Safe.
NOTE: The OPEN key on the OPI is always enabled.
When the control type is set to None a “Trip1” is
generated when pressed.
The Contactor control type selection is for applications
where an electrically held device such as a contactor is
used. An output relay must be assigned to Contactor.
In contactor-control mode, the CLOSE and OPEN
functions are operational. Control sources include the
OPI, digital inputs, and network communications. When
there are no trips and CLOSE is issued, the relay assigned
to Contactor will energize and stay energized until an
OPEN command is issued or a trip occurs. An OPEN
command operates the output contacts but does not
generate a trip, except when two-wire digital-input control
is used. In this case, an OPEN command will also issue a
“Trip1”, requiring a reset.
Use the 2-Coil Device control type selection to control
bi-stable devices such as a two-coil breaker. Two output
relays are used to control the device’s close and open/trip
coils. Assign two FPS output relays as CB Close and CB
Open in the Setup | Relay Outputs menu.
When a breaker with a close coil and undervoltagerelease coil is used, use the normally-closed contact of the
output relay that is assigned to CB Open. In this
configuration the contact opens momentarily to release
the breaker on an open request. Figs. 6.3 and 6.4 show
two examples of breaker control.
In 2-coil-device mode, the CLOSE and OPEN
functions are operational. Control sources include the
OPI, digital inputs, and network communications. When
there are no trips and CLOSE is issued, the relay assigned
to CB Close will energize for the maximum time duration

FPS Feeder Protection System
defined by the Close Pulse Time. When OPEN is issued,
the relay assigned to CB Open will energize for the time
duration defined by the Open Pulse Time. The full Open
Pulse Time is always used.
If status is not valid after the Open Pulse Time has
expired, the FPS will attempt an open retry. The retry
count is selected between zero (no retries) and five retries.
A time delay between successive retries is used and this
delay is also defined by the Open Pulse Time.
If the open status is not valid on power up, retries are
attempted based on the selected settings.
NOTE: For digital inputs set to 2-Wire Close, an OPEN
command generates a Trip1 and the FPS will indicate
“CB OPEN Press Trip”. Trip Sources must be set to
enable Trip1 or the breaker will close as soon as OPEN is
released.
6.2.1 CONTACT STATUS MONITOR
For the control type selection of Contactor and 2-Coil
Device, the device open/close status can be monitored by
a digital input connected to an auxiliary contact. Status
monitoring is enabled when a digital input is assigned as
52a Close Status or 52b Open Status. When 52a Close
Status is selected, the digital input should have voltage
applied (logic 1) when the device is closed and no voltage
(logic 0) when the device is open. When 52b Open Status
is selected, the digital input should have voltage applied
(logic 1) when the device is open and no voltage (logic 0)
when the device is closed.
During device operation, status must be valid within
the time specified by the Close Pulse Time for device
close operation and the Open Pulse Time device open
operation.
The FPS will issue a Trip1 and indicate a CB 52
Contact Trip if the status contact does not indicate a valid
status within the open or close pulse time. When in the
open or closed state, contact status is checked every 50
ms and a CB 52 Contact Trip will occur if the input status
is incorrect. If ac control voltage is used for the digital
input, it is recommended to program one of the inputs as
Control Power. See Section 4.2.9.

7. THEORY OF OPERATION
7.1 SIGNAL-PROCESSING ALGORITHMS
The FPS sampling rate is sixteen samples per cycle of
the fundamental frequency.
A Discrete-FourierTransform (DFT) algorithm is used to obtain the
magnitude and phase angles of the fundamental-frequency
components of the current and voltage waveforms. These
values provide true positive- and negative-sequence
components. True RMS values of line currents are
calculated for use by the thermal-model algorithm. RMS
values include up to the 8th harmonic. All calculated
values are updated at the sampling frequency to achieve a
fast response to fault conditions. RMS values of the
fundamental components of current and voltage are
displayed.
The FPS uses the input voltage VA for frequency
measurement. The input voltage must be above 30 Vac
and a sixteen-cycle interval is used to determine
frequency. Frequency protection is inhibited when
system voltage is less than 50% of the System Voltage
setting.
7.2 POWER ALGORITHM
Apparent power (S) is calculated by:
S  P  jQ
Real power (P) is determined from the in-phase
components of I and V, and reactive power (Q) is
determined from the quadrature components of I with
respect to V. Power factor is the magnitude of the ratio of
P to S.
The one-PT connection assumes balanced voltages for
power calculations. Power calculations for the other
connections are valid for both balanced and unbalanced
conditions. In all cases, power calculations use the twowattmeter method and assume three-wire loads.
The IEEE convention is used for power displays:

7.3 OPERATOR INTERFACE (FPS-OPI)
The OPI is a terminal device used to communicate with
the FPS-CTU. All set points, operating parameters, and
menus are stored in the FPS-CTU.
The OPI contains a microprocessor used to
communicate with the FPS-CTU, read key presses, and
perform display functions.
On multiple-OPI systems, all OPI’s display the same
information. Key presses on any OPI will be processed
by the FPS-CTU.
7.4 RTD MODULE (MPS-RTD)
The RTD module contains a microprocessor, A/D
converter, and analog multiplexers used to measure up to
eight RTD’s. The RTD-measuring circuit is isolated from
the I/O Module network. All eight RTD’s are scanned
every three seconds. RTD linearization, open/short
detection, and lead compensation are performed by the
RTD module. RTD temperature is sent to the FPS-CTU
where temperature monitoring occurs.
7.5 FIRMWARE DIAGNOSTICS
In the event of an internal fault, a diagnostic error code
is generated and can be viewed with the OPI. The last
error code can be viewed by selecting Setup  System
Config  Maintenance  Firmware Version.
The
diagnostic code is a two or three digit hexadecimal
number.

Relay-Control Algorithm Fault
Menu Display Fault
OPI Key Handler Fault
Real-Time Clock Fault

A/D Communication-Interface Fault
The last diagnostic error code is saved in non-volatile
memory. The diagnostic code is overwritten by any new
codes but can also be manually set to zero. To clear the
error code, press RESET while in the Firmware Version
menu.
A diagnostic error generates a Trip1 and increments the
trip counter, however, a trip record is not generated.

APPENDIX C
FPS MODBUS PROTOCOL
C.1 PROTOCOL
C.4 FUNCTION CODES SUPPORTED
®
The FPS implements the Modbus RTU protocol as
described in the Gould Modbus Reference Guide,
Publication PI-MBUS-300 Rev. B.
The communications system consists of a single master
and up to thirty-two FPS-CTU slaves connected using a
two-wire RS-485 network. If the master does not have an
RS-485 port, an RS-232 to RS-485 converter is required.
The converter must have automatic send-data control (SD).
SD control does not require hand-shaking lines since it uses
the data line to control the transmit/receive line on the
RS-485 transceivers.
Only the master can initiate a message transaction.
Messages can be addressed to individual slaves or they can
be broadcast messages. Broadcast messages are executed
on the FPS slaves but unlike individually addressed
messages, the slaves do not generate a reply message.
C.2 MESSAGE SYNCHRONIZATION
Message synchronization is accomplished by detection of
an idle communication line. The communication line is
considered idle when no communication exists for an
equivalent delay of 3.5 characters.
The first byte received after idle-line detection is
interpreted as the address byte of the next message.
Message bytes must be transmitted in a continuous stream
until the complete message has been sent. If a delay of
more than 3.5 characters exists within the message, the
message is discarded.
Response messages from the FPS are delayed by at least
3.5 character delays.
C.3 ERROR CHECKING
Modbus RTU uses a 16-bit cyclic redundancy check
(CRC). The error check includes all of the message bytes,
starting with the first address byte.
When a CRC error is detected, the message is discarded
and there will be no response.
If the CRC check is correct but the internal data in the
message is not correct, the FPS will respond with an
exception response code.
Modicon Modbus® is a registered trademark of Schneider
Electric.
The FPS Modbus Protocol supports the following
function codes:
 Read Holding Registers (Function Code 3)
 Read Input Registers (Function Code 4)
 Write Single Register (Function Code 6)
 Write Multiple Registers (Function Code 16)
 Command Instruction (Function Code 5)
Function Codes 3 and 4 perform the same function in the
FPS.
Registers in Modbus start at 40001 decimal and the
register address generated for this register is 0.
C4.1 APPLICATION LAYER
The hexadecimal system is used. Value representations
use the “C” convention. For hexadecimal, 0x precedes
the value.
C.4.2 READ INPUT/HOLDING REGISTERS (CODE 04/03)
The first byte of the read message is the slave address.
The second byte is the function code. Bytes three and four
indicate the starting register. The next two bytes specify the
number of 16-bit registers to read. The last two bytes
contain the CRC code for the message.

The two-byte values of starting register and number of
registers to read are transmitted with the high-order byte
followed by the low-order byte.
The CRC value is sent with the LSB followed by the
MSB.
The following message will obtain the value of register 1
(Modbus 40002) from slave 1. Note that Modbus registers
are numbered from zero (40001 = zero, 40002 = one, etc.):
0x01  0x03  0x00  0x01  0x00  0x01  0xD5  0xC
The addressed slave responds with its address and
Function Code 3, followed by the information field. The
information field contains an 8-bit byte count and the 16-bit
data from the slave. The byte count specifies the number of
Appendix C, FPS Modbus Protocol
Page C-2
Rev. 1-C-031615
FPS Feeder Protection System
bytes of data in the information field. The data in the
information field consists of 16-bit data arranged so that the
MSB is followed by the LSB.
The maximum number of 16-bit registers that can be read
is 120.
C.4.3 WRITE TO REGISTER
Function Code 6 or 16 is used to make set-point changes.
C.4.3.1 WRITE SINGLE REGISTER (CODE 6)
The function code format for writing a single register is
shown in Table C.2.
The message consists of the FPS address followed by the
Function Code 6 and two 16-bit values. The first 16-bit
value specifies the register to be modified and the second
value is the 16-bit data.
Provided no errors occurred, the slave will re-send the
original message to the master. The response message is
returned only after the command has been executed by the
FPS.
The following message will set register 3 to 300 in
slave 5:

C.4.5 COMMAND INSTRUCTIONS USING WRITE
COMMANDS
For PLC's not supporting Function Code 5, FPS
commands can be issued using Write Single Register (Code
6) and Write Multiple Register (Code 16).
Commands are written to FPS register 6 (Modbus register
40007).
Supported commands are listed in the
COMMAND CODE column in Table C.5.
When using the Write Multiple Registers function code,
the write should be to the single FPS Register 6. If multiple
registers are written starting at FPS Register 6, the first data
element will be interpreted as the command code but no
other registers will be written. If the command is
successful, the FPS will return a valid response message.
Appendix C, FPS Modbus Protocol
Page C-3
Rev. 1-C-031615
FPS Feeder Protection System
C.4.6 EXCEPTION RESPONSES
The FPS supports the following exception responses:
 Boundry Error (1)—Applies to writes of 32-bit
values. The high-order word must be written first
followed by the write to the low-order word. If this
sequence is not followed, a Boundry Error is returned
and the value will not stored. This does not apply on
read requests.
 Address Error (2)—All accesses to communication
registers must be within the specified address range
or the Address Error code is returned.
 Command Error (3)—This error code is returned if the
command code is not supported.
 Illegal Function Code (4)—The function code (Byte 2)
is not supported.
The exception message consists of the slave address
followed by a retransmission of the original function code.
The function code will have the most-significant bit set to
indicate an error. The 8-bit byte following the function code
is the exception response code. The 16-bit CRC is at the
end of the message.
C.5.2 CUSTOM DATA ACCESS
Data access can be customized with the User-Defined
Registers and the User-Data Registers.
User-Defined Registers are located in non-volatile
memory and contain the register numbers from which data
is required. To access the data, read the corresponding
User-Data Registers.
The format of the User Data is a function of the
corresponding register entered in the User-Defined-Register
area.
C.6 NETWORK TIMEOUT
The FPS can be configured to trip or alarm on a network
timeout using the Setup  Hardware  Network Comms
menu. The Net Trip Action and Net Alarm Action set points
set the actions to be taken when a timeout occurs. To
prevent a timeout, a valid message, addressed to the slave,

Appendix E contains the Modbus Register in the
Communications Database Table. The table starts at
register 0 (Modbus 40001) and each register is 16-bits wide.
Types “long” and “float” are 32-bit values. For both long
and float types, the low-order word is transmitted first
followed by the high-order word. Word values have the
high byte followed by the low byte. Float types as per IEEE
754 Floating-Point Standard. All bytes of long and float
types must be written using one message or an error will
result. This does not apply for read commands.

C.5.1 DATA RECORDS
Only one event record can be read at a time. Record data
is for the record indicated by the Record Selector. To select
a record, write the record number to Record Selector and
then read the values in the record. Record Head points to
the next available record. The last event record captured is
at Record Head minus one.
Both Record Selector and Record Head values are in the
range of 0 to 63. Values outside this range will select
record 0.

APPENDIX D
FPS A-B DF1 PROTOCOL
D.1 PROTOCOL
D.2 PLC-5 / SLC 500 CHANNEL-0 SETUP
The FPS A-B® Protocol is based on the half-duplex
master/slave Allen-Bradley (A-B) Data Highway Protocol
(DF1) as described in Allen-Bradley Bulletin 1770-6.5.16
October 1996. This publication is available from the A-B
web site at www.ab.com.
The communications system consists of a single master
and up to thirty-two slaves connected to a two-wire
RS-485 multi-drop network. FPS Control Units are slave
devices on this network.
If the master does not have an RS-485 port, an RS-232
to RS-485 converter is required. The RS-485 converter
should have automatic send-data control (SD). SD
control does not require handshaking lines since it uses
the data line to control the RS-485 transmitter. The
SE-485-DIN converter is recommended. It includes
optical isolation and baud rate selections from 9,600 to
57,600 bits per second. For additional information on
converters, see Technical Information TI 9.9.
The FPS supports the DF1 commands shown in
Table D.1. Each PLC has limitations when using a
particular command. Determine the best command to use
for a particular application.

The PLC-5 and SLC 500 support reading and writing to
integer files (Type N) and float files (Type F). Since FPS
meter values are float types, these will typically be stored
in a PLC Type-F file. It is also possible to read float
types from the FPS as two integers; however, further
processing is required to obtain the float value.
The PLC requires two communication ports—a PLC
programming port and an FPS communications port.
Typically, a DH+ port will be used for PLC programming
and the RS-232 port is used for FPS communications via
an SE-485-DIN converter.
A-B® is a registered trademark of Rockwell International
Corporation.
The RS-232 Channel-0 port is set up for a DF1 halfduplex master. Set the Channel-0 baud rate and CRC to
match the FPS settings. The parity bit is not supported on
the FPS. Where applicable, set Reply Message Wait to
100 ms.
Additional recommended PLC settings:
DF1 Retries = 3
RTS Send Delay = 1 (20 ms)
RTS Off Delay = 0
Ack timeout = 5 (100 ms)
Reply msg wait = 3 (60 ms)
For the polling mode, select MESSAGE BASED (DO
NOT ALLOW SLAVE TO INITIATE MESSAGES) or
STANDARD (MULTIPLE MESSAGE-TRANSFER
PER NODE SCAN). The FPS can buffer up to 3
messages. The selection MESSAGE BASED (DO NOT
ALLOW SLAVE TO INITIATE MESSAGES) is
recommended.
D.3 TYPED-READ
The Typed-Read message is used to read data from the
FPS. The Typed-Read message requires a Control Block
where the message configuration is stored. In the SLC,
this is normally N7:0 but could be any other file that
supports the control-block data. Use the following MSG
settings:
Read/Write:
Target Device:
Local/Remote:
Control Block:
Read
PLC5
Local
N7:0
NOTE: For the PLC-5, the message block must be of type
MG so that the channel number can be set in the message
setup screen.
The Setup screen is used to specify file information. In
the This Controller section, Data Table Address is the
destination in the PLC where data is to be stored. This
can be a float (Fx:x) file or an integer (Nx:x) file.
Element Size must be set to the number of elements to
transfer. This is a decimal value and this value is limited
in some controllers. In the SLC 500, the maximum value
for integers is 100 and for floats it is 50.
Appendix D, FPS A-B DF1 Protocol
Page D-2
Rev. 1-C-031615
FPS Feeder Protection System
In Target Device, set Data Table Address to the A-B
File address listed in Appendix E. The A-B File in
Appendix E is coded as FILE:ELEMENT. To read or
write the element as floats, the PLC-5 address would be
<F><FILE>:<ELEMENT> (Example F9:222). To read
or write the element as integers, add 20 to the file number
and preceed with N, <N><FILE+20>:<ELEMENT>
(Example N29:222). Local Address is the FPS address.
Example settings for reading 25 registers as float type
(25 meter readings):
Data Table Address: ..... F8:0
Element Size:................ 25
Target Device Data
Table Address:.......... F6:0
Local Address:.............. 9 (Must match FPS setting)
NOTE: To read float values, both data table addresses
must be specified as float (F) type.
Example settings for reading a block of 100 registers
(16-bit integer):
This could be a mix of float and integer values since
floats can be transferred as two integers in the FPS.
Data Table Address: ..... N9:0
Element Size:................ 100
Target Device Data
Table Address:.......... N23:264 (Start of Digital
Inputs)
Local Address:.............. 9 (Must match FPS setting)
If an FPS float has been read into the PLC as two
integers and stored in an N-type file, the float can be
recovered by using two copy commands. Assume that the
two integers from the FPS read command are stored in
N9:0 and N9:1. The first copy command is used to swap
the two words so they are in the correct order; copy N9:0
to N9:11, and copy N9:1 to N9:10. The second copy
command will copy the two integers to the F-type file;
copy N9:10 to F8:0 with a size of 1. The two integers are
now combined correctly as a single 4-byte float located in
F8:0.
D.4 TYPED-WRITE
The Typed-Write message is used to write data to the
FPS.
Read/Write:
Target Device:
Local/Remote:
Control Block:
Write
PLC5
Local
N7:0
The Setup screen is used to specify file information. In
the This Controller section, Data Table Address is the
source file in the SLC. This can be a float (Fx:x) file or
an integer (Nx:x) file. Element Size must be set to the
number of elements to transfer. For the FPS, the
maximum element size is 100 for integers and 50 for
floats.
In Target Device, set Data Table Address to the A-B
File address listed in Appendix E. Both integer and float
values sent from the SLC are in the correct byte order and
interpreted correctly by the FPS. The FPS will do a range
check on all messages to ensure valid data.
Local Address is the FPS address.
Example settings for writing a single float to set the
FLA Rating:
Data-Table Address: .....F8:0 (Location of FLA value)
Element Size: ................1
Target-Device DataTable Address: ..........F3:225
Local Address: ..............9 (Must match FPS setting)
Reset commands to the FPS are issued by writing an
integer command code to FPS Register 6 (N23:6)
A command message should only be issued when the
command is required.
Valid commands are shown Table D.2.

D.5 UNPROTECTED READ/WRITE
D.9 NETWORK TIMEOUT
For PLC-2 and PLC-3 processors not supporting Typed
Read/Write
messages,
Unprotected
Read/Write
commands can be used. For these messages, the data
address is the Octal value of the FPS Register in
Appendix E. The size is the number of registers. The
maximum number of registers that can be transferred in a
single message is 100.
Unprotected Read/Write commands are used by the
SE-Comm-FPS communication program.
The FPS can be configured to trip or alarm on a network
timeout using the Setup  Hardware  Network Comms
menu. The Net Trip Action and Net Alarm Action set points
set the actions to be taken when a timeout occurs. To
prevent a timeout, a valid message, addressed to the slave,
must be received at time intervals less than five seconds.
D.6 TYPED LOGICAL READ/WRITE
The Typed Logical Read (CMD = 0F, FNC = A2) and
Typed Logical Write (CMD = 0F, FNC = AA) messages are
supported by the full line of SLC 500 processors and Prosoft
MVIxx-DFCM communication interfaces.
Both float (F) and integer (N) types are supported.
Unlike the typed commands in Section D.3 and D.4 a file
offset is not required for integer values. Use the A-B file
address as listed in the FPS manual Appendix E and precede
the address with F for float values and N for integer values.
The maximum number of integers and floats that can be
read is 100 and 50 respectively.
Reset commands to the FPS are issued by writing one of
the COMMAND CODES listed in Table D.2 to Register 6
(N3:6).

NOTES:
(1)
The A-B File is coded as FILE:ELEMENT. To read or write the element as floats, the PLC-5 or SLC 500 address
would be <F><FILE>:<ELEMENT> (Example F9:222). To read or write the element as integers using
PLC-5 Typed Read and Typed Write commands, add 20 to the file number and precede with N,
<N><FILE+20>:<ELEMENT> (Example N29:222). File offset not required for SLC 500 Protected Typed Logical read
and write commands.
(2)
Undefined registers in this table read zero. Registers greater than 1463 return error.
(3)
The following MPS-RTD error codes are supported:
-100 = No RTD Sensor
-90 = Open Sensor
-80 = Shorted Sensor
-70 = No Data/Module Communication Error
(4)
