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.

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.
