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 LOVfryer systems. (See next page for bulk oil wiring.)

The LOVfryer will ONLY operate with RTI systems that have the new RTI updated three- pole float switch. If the float switch is the older two-pole switch, call RTI. These float switches are polarity specific and may short to ground and damage an MIB board.

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.
