F P.C. BOARD (Data processor)
The P.C. BOARD, fitted in its plastic box located
in the front of the unit, consists of two separated
printed circuits one at high and the other at low
voltage and protected by fuses. Also it consists
of five aligned LEDS monitoring the operation of
the machine of three jumpers (TEST used only
in the factory, 60/70°C used to set up the PC
Board at proper safety cut out condensing tem-
perature and 3' to by pass the 3 minutes Stand
By) and of input terminals for the leads of the
sensor probes as well as input and output ter-
minals 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 pro-
cessor, the signals received from the sensors in
order to control the operation of the different
electrical components of the ice maker (com-
pressor, gear motor, etc.). The five LEDS, pla-
ced in a row in the front of the P.C. BOARD,
monitor the following situations:
GREEN LED
Unit under electrical power
YELLOW LED
Blinking: I/R beam cut out
Steady: unit shut-off at storage bin full
Blinking fast: I/R beam resumed
YELLOW LED
Unit shut-off due to a too
lo-water level into float tank
RED LED
ON ALL THE TIME
- Unit shut-off due to a too
hi-condensing temperature
- Unit shut-off due to a too
lo-ambient temperature <+1°C
BLINKING
3 minutes start up delay time
YELLOW LED
ON ALL THE TIME
- Unit shut-off due to the wrong
rotation direction of gear motor
- Unit shut-off due to the
too lo speed of gear motor
BLINKING
- Unit shut-off due to a
too hi-evaporating temp.
>-1°C after 10 min of operation
TO BY-PASS THE 3'/60' STAND BY TIME, SYMPLY JUMP "TEST" CONTACTS
