H. P.C. BOARD (Data processor)
The P.C. BOARD, fitted in its plastic box located
in the right side of the unit, consists of two separated
printed circuits one at high and the other at low
voltage, protected by three fuses, integrated with
a RE-SET button. Also it consists of six aligned
LEDS monitoring the operation of the machine
and of input terminals for the leads of the sensor
probes as well as input and output terminals for
the leads of the ice maker electrical wires.
The P.C. BOARD is the brain of the system and
it elaborates, through its micro processor, the
signals received from the sensors in order to
control the operation of the different electrical
components of the ice maker (compressor, gear
motor, etc.) as well as the dispensing of the ice
and water.
The six LEDS, placed in a row in the front of the
P.C. BOARD, monitor from right to left the
following situations:
RED LIGHT
