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 (4 A), of four connectors for the sensors/
switches (condenser sensor - BLACK -, two
magnetic switches - BLUE - ice thickness sensor
- RED -), of two jumpers (one J1 for the selection
between models MV 21-32 - one magnetic switch
- and the model MV 50 - two magnetic switches
- and the second J2 for the selection between
manual or automatic reset mode), of one outlet
connector (front LED display - black) and of five
plug in terminals for input and output power.
With the two upper pins of the P.C. Board jumped
the same is set up in automatic reset mode while
when disconnected is in manual reset mode.
With the bottom ones jumped the P.C. Board is
set up to operate with one magnetic switch
(MV 21 and MV 32); when disconnected is set up
for two magnetic switches (MV 50).
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 40 minutes and trip-off complete unit when
defrost cycle is longer then 3 minutes (Red LED
