the service and inspection operations.

IN OPERATION: The unit is running through the freezing and defrost cycle stopping automatically only at full bin situation.

RE-SET/HI TEMPERATURE: To be selected to resume the unit operation when the ice maker shuts off due to the intervention of the condenser temperature sensor (too high condensing temperature).

The five LEDS, placed in a row in the front of the P.C. BOARD, monitor the following situations:

GREEN LIGHT: Unit under electrical power

YELLOW LIGHT: Unit shut-off at full storage bin

RED LIGHT: Unit shut-off due to hi-condensing temperature

Blinking:Unit shut-off due to hi-evaporating temperature

YELLOW LIGHT: Unit in freezing operation

YELLOW LIGHT: Unit in cleaning/rinsing mode

12.6 DIP SWITCH

The P.C. BOARD which controls the entire operation of the ice maker, has a DIP SWITCH with ten switching keys which allow to set up the micro processor program in order to extend or to shorten the length of freezing and defrost cycles in relation to the different models and versions of ice machines.

The DIP SWITCH first four keys setting determines the length of the 2nd phase of freezing cycle (controlled by the electronic timer) as detailed in Table B.

The DIP SWITCH keys 5, 6 and 7 setting determines the length of the defrost cycle according to the ambient temperature sensor as specified in table C.

The 8th DIP SWITCH key allows to make a rapid check up of the P.C. BOARD output connections (compressor, water pump, fan motor, water inlet and hot gas solenoid valves) energizing them in rapid sequence (2 seconds) one by one.

DURING THE AUTOMATIC OPERATION OF THE ICE MAKER THIS KEY MUST BE SET IN OFF POSITION.

ATTENTION: The check up of the P.C. BOARD output must be performed in a very short time in order to avoid frequent starts and stops (every few seconds) of the electrical components which may damage them, especially the compressor.

The 9th key allows the operation of the water pump even during the defrost cycle. On B 90 it must be set all the time to OFF position.

The 10th key is used to supply power to the water pump during the first 15-20 seconds of the defrost cycle to drain out all remaining water from the sump tank in the unit equipped with the solenoid drain valve i.e. the KWD drain system.
