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 fl oat switch. If the fl oat switch is the older two-pole switch, call RTI. These fl oat switches are
polarity specifi c 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 fi ll 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:
Reset the power; wait 60 seconds and see if the valve opens.
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 fi lling:
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.
