LOV™ Generation II Technical Reference
RTI-equipped Systems
Some stores may be equipped with RTI oil storage systems. If so, some of the settings, wiring, and troubleshooting may differ from normal LOV™ fryer systems. (See next page for bulk oil wiring.)
The LOV™ fryer will ONLY operate with RTI systems that have the new RTI updated three- pole float switch. If the float switch is the older
Normal AC Voltage Measurements (MIB J6 8 pin connector with everything connected)
•Pin 1 to Pin 2 - 24 VAC.
•Pin 2 to Pin 8 - 24 VAC when waste tank is full, 0 VAC when it is not full.
•Pin 2 to Pin 3 - 24 VAC when RTI fill pump is on, 0 VAC when it is off.
Troubleshooting
The valves and pump should be off while MIB is resetting. If any of the valves or pumps are on dur- ing reset then the MIB board is bad or wires are shorted.
If JIB valve is not opening, measure when JIB valve supposed to be open:
•Voltage at MIB board from Pin 1 to Pin 2 should be 24 VAC; if not, check connections from RTI 24VAC transformer and check transformer.
JIB solenoid is not opening:
Take these readings when the JIB valve is in the open position:
1.Reset the power; wait 60 seconds and see if the valve opens.
2.Check voltage at ATO board on J8. Pin 9 to Pin 16 should be 24 VAC.
RTI pump is not operating or JIB is not filling:
1.Voltage at MIB board from Pin 1 to Pin 2 should be 24 VAC; if not, check connections from RTI 24VAC transformer and check transformer at RTI.
2.Voltage at MIB board from Pin 2 to Pin 3 should be 24 VAC; if not, check MIB board is bad or wires to pump relay are shorted or both.
3.Voltage at Add pump relay should be 24 VAC; if not, check wiring from MIB board. Relay located on top of RTI system.
Waste full signal: Pin 2 to Pin 8 should be 24 VAC when full, 0 VAC when not full; if no voltage level change, then the connection from RTI switch or MIB board is bad.
