Bulk Oil Service Issues

1.21.1 Bulk FIB Tests

These instructions may NOT be applicable to all bulk oil systems.
The FilterQuick-T™ fryer will ONLY operate with a three-pole float switch for waste oil. If a two-
pole switch is used it may cause damage to the FIB board. The float switches are polarity specific
which may short to ground and damage an FIB board.
AC voltage measurements from the bulk oil connector on rear of fryer:
Pin 1 to Pin 2 - 24 VAC.
Pin 1 to Pin 4 - 24 VAC when waste tank is full, 0 VAC when it is not full.
Pin 1 to Pin 3 - 24 VAC when bulk fresh oil add switch and pump is on, 0 VAC when it is off.
Troubleshooting
All return and drain valves should be closed and pump should be off while the FIB is resetting. If any of the valves or
the pump is on during reset, the FIB board is bad, or wires are shorted.
Bulk fresh oil pump is not operating, or Oil Reservoir is not filling:
NOTE: DO NOT CHECK PINS WITH HARNESSES UNPLUGGED AS SHORTING THE PINS MAY OCCUR WHICH WILL
DAMAGE THE BOARD.
Normal measurements (FIB C6 15-pin connector with everything connected)
See section 1.21.5 to ensure that no other function is taking priority over adding oil to jug.
1. Reset the power; wait 60 seconds and see if the valve opens.
With the Orange JIB (Oil Reservoir) button pressed:
2. Voltage at FIB board C6 from Pin 5 to Pin 6 (FIB board J1 from Pin 21 to Pin 22) should be 24 VAC; if not, check
connections from bulk fresh oil 24VAC transformer and check transformer.
3. Voltage at FIB board C6 from Pin 6 to Pin 7 (FIB board J1 from Pin 21 to Pin 23) should be 24 VAC when filling JIB
or vat; if not, the FIB board is bad or wires to pump relay are shorted or both.
4. Voltage at Fresh Add Pump Relay should be 24 VAC; if not, check wiring from FIB board. The relay is located on
top of some fresh oil bulk systems.
Waste full signal:
Voltage at FIB board C6 Pin 5 to Pin 8 (FIB board J1 from Pin 22 to Pin 24) should be 24 VAC when full, 0 VAC when
not full; if no voltage level change, the connection from bulk waste full switch or FIB board is bad.
