FloTech Programmable CheckMate Retain / Overfill Monitor
Monitor's PERMIT and AUX LEDs are ON, all
sensor LEDs are OFF, but the rack will not load.
This condition usually indicates:
 The sensors and sensor wiring are functioning.
 The monitor has the proper power.
 The AUX connections are OK.
 Defective ground bolt or connections (if equipped).
 Socket output failed or socket wiring problem.
The problem usually lies in the monitor output, socket wiring or
the socket itself. To troubleshoot this condition, use the
FloTech FT520 Optic System Tester.
1. Check the system by connecting a FloTech FT520 Optic
System Tester. Check for a good light on all compartments.
2. If not permissive then check all wiring connections, poor
crimp connections, or worn J slots on socket faceplate.
NOTE: The ground hog bolt can fail or have a bad ground
connection and not allow the tank to load. This is an
independent system not part of the overfill system and is
prone to problems.
3. If wiring connections check OK, test TB5 on the monitor
using the FT520 Optic System Tester. The FT520 Optic
System Tester is the only positive way to directly test Optic
or Thermistor outputs. Follow the directions supplied with
the FT520.
System with Retain sensor will not reset when
splash blending.
1. Check continuity of reset switch with ohmmeter. When the
switch is depressed the contacts are closed. If the switch is
failed then replace with a FloTech FT9011 replacement
switch.
2. If the switch tests OK then replace the monitor.
