2. P.C. Board
Located in the control box, this board is the brain of the
system as it governs the ice machine cyclematic
through sensors, relays and switch. It consists of two
separated printed circuits one at high and the other at
low voltage integrated with a fuse, of four connectors
for the sensors/switches (condenser sensor - BLACK -
, magnetic switch - GREEN - ice thickness sensor -
RED - water level sensor - BLUE), of two jumpers (one
J1 for factory use only - and the second J2 for the
selection between one water fill up or continuous water
fill up), of one outlet connector (front LED display -
black) one serial port connector (black) and of four
plug in terminals for input and output power.
With J2 closed the P.C. Board is set up for water fill up
at beginning freeze mode. When J2 is open the PC
Board is set up for continuous water filling mode.
The P.C. Board is equipped by an electronic safety
timer that turns-on automatically the unit to defrost
cycle when freezing cycle is longer then 30 or 40 min-
utes and trips-off completely unit when defrost cycle is
longer then 3,5 minutes (4th Red LED ON).
A trimmer, located close to the transformer, can
change the current received back from the Ice
Tickness
Sensor
according
to
the
Electrical
Conductivity of the water.
3. Compressor Contactor
Located in the control box, the compressor contactor
functions to carry the compressor line current. The
contactor is wired to receive power from the P.C.
Board.
