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 minutes 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.
