Description
The Sentinel II is a unique, powerful level transmitter.
The leading-edge microprocessor-based circuitry has
non-volatile memory that requires no battery backup. To
simplify troubleshooting, powerful diagnostics not only
check all aspects of the system, but will actually indicate
the faulty section of the system. MagneCal™ offers the
user the greatest improvement in RF Capacitance—one
small level change (2% of span) is needed to calibrate.
1.1
Principle of Operation
The amount of capacitance developed in any vessel is
determined by the size (surface area) of the probe, the
distance from the probe to its ground reference, and the
dielectric constant of the medium being measured.
Assuming that the probe's mounting position and the
dielectric of the medium are fixed, the amount of capacitance developed in any vessel becomes dependent upon
the probe's diameter and length. Adjusting the combination of the probe's diameter and length (and its proximity
to a ground reference) can generate the necessary capacitance required by the electronic circuitry.
As the media rises and falls in the tank, the amount of
capacitance developed between the probe and the ground
reference also rises and falls. The capacitance-controlled
oscillator circuit mounted on the probe changes the
capacitance signal to a a digital wave form—proportional
to the change in level. The Series 804 amplifier then
converts this digital pulse signal into an isolated 4–20 mA
analog output signal.
1.2
Unpacking
Unpack the instrument carefully making sure all components have been removed from the packing material.
Inspect all components for damage and report any concealed damage to the carrier within 24 hours.
Check the contents of the carton making sure it agrees
with the packing slip and the purchase order. Verify that
the model number imprinted on the nameplate matches
the number on the packing slip and the purchase order.
Report any discrepancies to the factory. Check and record
the serial number for future reference when ordering parts.

1.3
Connecting Cable
Remote mount connecting cable should be shielded,
twisted pair, 22-gauge stranded conductors and may be
ordered as Magnetrol part number 009-7146-001. Cable
length in feet must be specified at time of order; 2500 feet
(760 m) maximum; 800 feet (240 m) maximum for intrinsically safe models.
2.0
Installation
Caution: Carefully read this entire section prior to installation.
2.1
Installation Location
Kotron Sentinel II Transmitters should be placed in a location which allows easy access for service, calibration, and
monitoring. Electronics should not be exposed to ambient
temperatures below -40° F (-40° C) nor above +160° F
(+70° C). Special precaution should be taken to prevent
exposure to corrosive atmosphere, excessive vibration,
shock, or physical damage.
It is common practice to use the metal tank wall as the
ground reference. When doing this, it is required that the
probe housing make a good electrical connection to the
tank wall. If there is any doubt about this connection
(rust or using PTFE thread tape, gaskets, or paint may
impede this connection), then a separate strap should be
installed between the probe housing and the tank.
Sensing probes should be located close to the tank wall for
greatest sensitivity in non-conductive media. Isolate probes
from severe motion in the tank because surface turbulence
may cause signal deviation.
Caution: This unit contains CMOS electronics that could be
damaged by static electricity. Do not touch any semiconductor devices unless you are properly grounded.
Metal-Walled Tanks
On water-based liquids, a problem should not be encountered with sensitivity or linearity. With non-conductive,
low dielectric media, sensitivity can be enhanced by locating the probe close to and parallel with the tank wall. If
this is not practical, a concentric ground tube surrounding
the probe (a stilling well) may be a solution.
50-604 Kotron Model 804 Sentinel II RF Level Transmitter
2
Tanks/Silos with Non-Conductive Materials
of Construction
With plastic, concrete, wood, or any other non-conductive
walled vessel, the reference electrode (mentioned in the
Principle of Operation section on page 1) needs clarification. Most commonly, this electrode will be in the form
of a concentric ground tube (for example, a stilling well).
In questionable circumstances, consult the factory. In all
cases, a good electrical connection must be made between
the ground surface and the probe housing.
NOTE: These comments also apply to glass-lined, metal walled tanks.
Caution: When an insulated probe is used in a hazardous and/or
abrasive medium, the probe should be inspected annually
for nicks, cuts, or abrasions, which may ruin the integrity of
the insulation. In the event that wear is found, replace the
probe or consult the factory for further instructions. This
procedure is critical in vessels containing hazardous media.

Mounting
Probes should be mounted vertically and such that the
probe rod is at least 2" (50 mm) below the lowest
desired level control point with conductive materials; or,
4" (100 mm) below the lowest desired level control point
in non-conductive materials. Refer to Figure 1.
2.2.1 Mounting Procedure
Kotron Sentinel II Transmitters with standard probes up to
and including 12" (305 mm) in length are shipped preassembled. Units with standard probes over 12" (305 mm)
in length are shipped unassembled to avoid damage during
transit; and must be assembled before mounting. Follow
the proper mounting procedure for specific unit.
NOTE: Before beginning mounting procedures, ensure that the power
source to the unit is off. After installing the probe on the tank,
and before wiring the electronics to the probe, it is beneficial
to perform a probe resistance check to verify the integrity of
the probe.
The resistance of an insulated probe in conductive liquid (or a
bare probe in non-conductive media), when measured
between the probe screw terminal and the probe mounting
nut with an ohmmeter set to its 20 megohm scale, should
be INFINITE.
2.2.2 Integral Mount with Standard Rigid Probe

Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol/STIs electronic instruments are manufactured
to the highest quality standards. These instruments utilize
electronic components which may be damaged by static
electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge:
1. Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap board in aluminum foil.
Do not place boards on foam packing materials.
2. Use a grounding wrist strap when installing and
removing circuit boards. A grounded workstation is
also recommended.
3. Handle printed circuit boards only by the edges. Do not
touch components or connector pins.
4. Ensure that all electrical connections are completely made
and none are partial or floating. Ground all equipment to
a good, earth ground.

2. Connect the control room converter wire B to terminal B.
NOTE: Polarity among units in loop must be observed.
3. If connecting multiple 804 units in a daisy chain configuration, be sure to connect the wiring in parallel and have
the ending 804 unit with the termination resistor
jumpered. The termination jumper pins are located under
the shield, below the RS-485 terminal block. The jumper
(JP1) should be in positions 2 and 3, removed on all units
except the last one in the chain. The last unit should have
the jumper in positions 1 and 2.
4. Proceed to Unit Configuration section on page 11.
NOTE: If connecting several units, note the color wire used for A and
B; ensure that the same designated color is used for each
of the units.

These calibration points do not have to correspond
with the 4–20 mA output settings or any discrete output set point; they are two arbitrary points along the

Troubleshooting
Caution: In hazardous areas, do not remove housing until power is
disconnected and atmosphere is determined to be
safe.The Sentinel II contains a comprehensive diagnostics
system that can assist in locating the cause of a specific
fault. This system also allows the user to test the 4–20 mA
and discrete (relay) outputs to ensure satisfactory operation of the system. The following section defines each
function of the diagnostics system:
3.1.1 Test Relays
The Test Relays menu provides a controlled contact
closure for each relay to test its integrity. A password is
required.
3.1.2 Test 4–20 Output
The 4–20 Loop Output menu provides a means for testing
the 4–20 mA output. Once the desired loop current is
entered, the Model 804 will drive the output loop to this
current value.
3.1.3 Signal Values
The Signal Values menu provides a means of examining
the signals between the probe and the CCO (Capacitance
Controlled Oscillator). The three signals are:
3.1.3.1 CCO int. cap.
This signal represents the time period of the oscillator
using the internal test capacitor. This fixed capacitor is
switched into the circuit to test the oscillator. A value of
approximately 475 and 525 µsec. is acceptable.
3.1.3.2 Open probe
This signal represents the time period of the oscillator with
no capacitor attached (the probe and the fixed capacitor
are switched out of the circuit). A value between 150 µsec.
and 250 µsec. is acceptable.
3.1.3.3 CCO probe
This signal represents the time period of the oscillator
using the probe’s capacitance The minimum should be
equal to or greater than the open probe value; the maximum should not exceed 70,000 µsec.

3.1.4 View Version #
The View Version # menu enables the user to verify the

3.1.5 Factory Presets
The Factory Presets menu allows setting of special factory
functions. This menu should only be used with guidance
from factory personnel. Contact the factory for assistance.
3.1.6 Troubleshooting Procedures
The chart below describes error messages that can appear
on the Sentinel II display.
Display
21
Cause
Solution
Open
probe
The capacitance being
measured by the unit is too
low. Possible causes include
missing probe; missing/broken
probe wire; or a poorly
connected probe wire.
Shorted
probe
Probe resistance between the
center connection and mounting nut is less than 1 megohm.
Possible causes include a bare
probe in conductive media or
a damaged insulated probe in
a conductive media.
Check the probe resistance
by connecting an ohmmeter
between the center connection and the mounting nut.
If the resistance is less than
infinity, contact the factory.
Probe
error
Probe capacitance exceeds
50,000 pF.
Contact the factory for
application assistance.
No
return
signal
Occurs when the oscillator is
not receiving a signal. Possible
causes include a shorted
probe; missing/broken interconnection cable between
the preamplifier and the main
electronics (remote only); or
a defective circuit board.
If the probe is a shorted
probe, follow the instructions above for shorted
probe.
Check the interconnection
wire between the probe
and the preamplifier.

Service Policy
Return Material Procedure
Owners of Magnetrol/STI controls may request the
return of a control or any part of a control for complete
rebuilding or replacement. They will be rebuilt or replaced
promptly. Controls returned under our service policy
must be returned by prepaid transportation.
Magnetrol/STI will repair or replace the control at no cost
to the purchaser (or owner) other than transportation if:
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the factory, prior to the material's return. This is available
through Magnetrol’s local representative or by contacting
the factory. Please supply the following information:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to
be covered under the warranty.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this
is desired, notify the factory of both the model and serial
numbers of the control to be replaced. In such cases, credit
for the materials returned will be determined on the basis
of the applicability of our warranty.
No claims for misapplication, labor, direct or consequential damage will be allowed.
