ELECTRICAL SYSTEM
The Superflakers models MF 59 and MF 69 use, like
their compact versions MF 56/66, the typical PC
Board used in our Flaker machines.
On model MF 69, in addition to the Main PC Board, it
is also used the interface PC Board of the model MF
66 so to have the possibility to control the operation
of two different drive motors and optical ice level
controls.
On the back side of the unit there is a open hole
(plugged with a rubber cup) to electrically connect the
PC Board to a remote control (Timer and/or remote
switch)
PC BOARD
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,
protected by a varistor on power IN and by a fuse on
power OUT, integrated with six small jumpers and an
water sensitivity adjusting trimmer.
Also it consists of five aligned
LEDS
monitoring the
operation of the machine and of input terminals for
the leads of the sensor probes as well as 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 sensors in order to control the
