3) Check the Controller Board by using test program of the Controller Board.

The Output Test Switch “S3” provides a relay sequence test. With power OFF, place S3 on and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, and 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.

3. SWITCHES

Two control switches are used to control operation in the KML Series Modular Crescent Cubers. These switches are referred to as the “Control Switch” and the “Service Switch.”

[a] CONTROL SWITCH

The Control Switch is located on the lower left section of the control box when facing the front of the machine. This switch is used to place the machine into one of three modes: “Power Off” (Center position), “Ice Making” (Right position), and “Service” (Left position).

[b] SERVICE SWITCH

When the Control Switch is pushed to the left, the machine is placed in “Service” mode. In this position the Control Switch supplies power to the Service Switch. The Service Switch can be used to perform three functions: Drain the tank (left position), Circulate water (center position), Wash the ice making compartment (right position). When the Service Switch is activated power is supplied to the pump in all three positions.

1) Drain

The KML series utilizes a pump-out drain system. When the Service Switch is active and placed in the left position, power is supplied to the pump and the Drain solenoid valve.

2) Wash

The KML series utilizes a solenoid operated cleaning valve. When the Service Switch is active and placed in the right position, power is supplied to the pump and the Bypass solenoid valve. This cleans both the inside and outside of the evaporator plate assembly.

3) Circulate

When the Service switch is active and placed in the center position, power is supplied to the pump only. This operation can be used to circulate cleaner for extended periods of time over the outside surface of the Evaporator.
