In case the condenser temperature rises and
reaches 70°C (1 60°F) - on air cooled models - or
62°C (145°F) - on water cooled models - the
current
arriving to the micro processor is such to
cause an
immediate and total stop of the machine
operation.
C. ICE BIN LEVEL LIGHT CONTROL
The electronic ice bin level control, located
into the storage bin, has the function to stop
the operation of the ice machine ONLY AT
THE END OF THE HARVEST CYCLE when
the light beam is interrupted by the ice cubes
stored into the bin.
When the light beam is interrupted the Bin Full
YELLOW LED starts blinking
.
SETTING OF THE ICE LEVEL CONTROL
SENSIVITY
In case of any need it's possible to up to date
calibrate the sensivity of the optical ice level
control just by turn OFF and ON the Power
supply by main switch.
NOTE. The setting of the Ice Level Control
Sensivity must be done any time a new PC
Board or a new lce Level Control is installed
in the machine.
D. 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 integrated with fuse on power out (6.3
A), of four aligned LEDS monitoring the
operation of the machine, of one extra
monitoring RED LED (blink 0°C - steady -
15°C), of one DIP SWITCH with ten keys, of
one push button, of input terminals for the
leads of the sensor probes and 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 three sensors in order
to control the operation of the different electrical
components of the ice maker (compressor, water
pump, solenoid valves, etc.).
