Pitco Solstice and Solstice Supreme High Efficiency Gas Fryers
Relay Board
NOTE: J connectors are marked on the relay board.
With 24 VAC supplied to pin #2 at connector J35 and a good F1 fuse, the relay board has a 24 VAC output at pin #2 on connectors J33 and J34 and the AC indicator is illuminated.
NOTE: If the fryer is equipped with a computer or solid state digital, at connection J33 there is a jumper from pin #2 to pin #10 to supply 24 VAC to pin # 2 at connection J31 to supply the controller with 24 VAC.
When the board receives a 24 VDC SO input at pin #7 on connector J31 or J33, the SO indicator is illuminated, the SO relay is energized, and there is a 24 VAC output at pin #4 on connector J32.
When the board receives a 24 VDC HD input at pin #6 on connector J31 or J33, the HD relay is energized and there is continuity between pin #1 and pin #2 at connector J32. The HD indicator is illuminated from the 24 VAC output from the HD relay NO contact.
NOTE: The HD indicator does not illuminate if there is not a 24 VAC output from the MV terminal on the ignition module.
Computer Control
NOTE: All controller test points are at connector P/J1 (closest connector to the controller).
With 24 VAC supplied to pin #1(24 VAC supply) and pin #5 (24 VAC input from DVI), the display reads “OFF”.
With the controller is turned on, there is a 24 VDC output at pin #9 (SO).
When the controller calls for heat, there is a 24 VDC output at pin #8 (HD) and a 24 VAC input at pin #6 (HFB). If the controller does not receive the 24 VAC input at pin #6 in approximately 90 seconds, the controller displays “HEAT FAIL” or “IGNITION FAILURE”. This indicates a break in the HD or HFB circuit.
To correct, do the following:
1.Check the
2.Check the ignition module (sensing pilot flame, locked out, 24 VAC at MV terminal).
3.Check the HD relay on the relay board. Is the HD relay energized continuity through COM and NO contacts?
If display reads “PROBE OP” “OPEN”, Ω test the temperature probe. Check the wires and connectors between the probe and controller for continuity.
If display reads “SYSTEM” ‘FAILURE”, Ω test the temperature probe, and the wires and connectors between the probe and controller for a short.
If display reads “DRAINING” “TURN OFF”, verify that the drain valve is closed, check the proximity switch on the drain valve, turn the fryer off, and then turn the fryer on.
