If fuse is blown, A.C. will not be lit.
When lit, F1 Fuse and T1 Transformer are good.
When lit, A1 Computer is on and K10 Contactor should be energized.
When lit, A1 Computer is on and calling for heat, K11 Contactor should be energized
Heat Demand Relay, will be energized when A1 Computer calls for heat and when H.D. is lit.
Side On Relay, will be energized when A1 Computer is on and A.C. is lit.
Connects to A1 Computer
To Side On and Heat Demand Contactors and Heat Feed Back.
To 24VAC jumper harness.
To Drain Switch and optional Basketlifts
Input voltage from transformer
Relay Board:
Note:
Note: If the fryer is equipped with a
computer or solid state digital, at
connection J33 there will be a
jumper from pin #2 to pin #10 to
supply 24 VAC to pin # 2 at
connection J31 to supply the
controller with 24VAC.
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 will have a 24 VAC output
at pin #2 on connectors J33 and J34
and the A.C. indicator will be
illuminated.
•When the board receives a 24 VDC
side on input at pin #7 on connectors
J31 or J33, the S.O. indicator will
illuminate, the side on relay (S.O.) will
energize and there will be a 24 VAC
output at pin #4 on connector J32.
•When the board receives a 24 VDC
heat demand input at pin #6 on
connectors J31 or J33, the H.D.
indicator will illuminate, the heat
demand relay (H.D.) will energize and
there should continuity between pin #1
and pin #2 at connector J32.
