FloTech Programmable Retain / Overfill Monitor
exchange failed sensor wire TOP #3 (yellow) with the
working TOP #2 wire (orange).
4. If the lit sensor LED does not move to the new position,
the monitor is defective. Example: LED TOP #3 top
stays lit after the sensor wires are switched. Replace the
onboard monitor chassis with a FloTech model FT203P.
5. If the lit sensor LED moves to the new switched
compartment, the problem is with the sensor or wiring.
Example LED TOP #3 go out and LED TOP #2 lights,
return the wires to the original positions.
6. Open all the sensor caps and check each wiring
connection. Look for pinched wires that may short the
sensor signal to ground. Also, look for defective crimp
connections.
7. Measure voltage across the failed sensor wires (Black to
Red). Voltage should measure 8-10 VDC.
8. If steps 6 and 7 check OK, replace the sensor with a
FloTech FT201.
NOTE: A quick test of the sensor can be accomplished by
connecting the sensor directly to the onboard monitor.
Example: Remove sensors wires from ground (black) and the
TOP sensor 1 (red) and connect the sensor to be tested. If the
sensor is good the RED TOP #1 LED with NOT light. If the
sensor is defective the Diagnostic LED WILL light.
System will not load, has no green AUX LED
and no green PERMIT LED, power LED is lit
and no red sensor LEDs are lit.
1. Check the TB4 AUX input. This input must have a
closed switch or jumper connected to allow the monitor
to load. The AUX input has it‟s own green LED. This
LED must be lit to send a permissive signal to the load
rack.
2. Check to see if a jumper is connected to TB4. If TB4
has no connections, add a jumper.
