a The contacts 2,4 and 6 of the Safety Contactor (KO)
b The terminals 2 and 5 of the Control Power Switch (S1)
2 When the Control Power Switch (S1) is turned on (closed)
a The red light on the switch is energized.
b Incoming power (220 VAC) is sent through the 2A fuse (F1.1) to
The 12 vdc power supply (G1)
12vdc is sent to terminals 3 and 4 of the connector X10 on the Control
Board (A10)
Terminal 1 of connector X12 on the Control Board (A10)
Terminal 10 of connector X13 on the Control Board (A10)
The return of the Supply is sent to terminal 7 of connector X13 on the Control
Board (A10)
c With 220 VAC to the Control Board (A10) The Operation Board (A11) is
energized
An alarm will sound for one second
All the LED’s and the display will energize one at a time.

b The fan circuit is energized
If the combi fan is in the normal setting 220 VAC is sent from terminal 5 on
connector X11 through the normally closed auxiliary contacts of contactor
K57 to the coils of contactors K55 and K56
The K55 and K56 contactors close sending 220 VAC through the Q56
overload to the motor and the motor turns at a high speed.
The normally closed auxiliary contacts of both K55 and K56 open
preventing the K57 contactor from energizing.
