DIP SWITCH
The P.C.BOARD which controls the entire
operation of the ice maker, has a DIP SWITCH
with ten switching keys which allow to set up
the micro processor program in order to extend
or to shorten the length of freezing cycle in relation
to the different model and versions of ice machines.
The DIP SWITCH first four keys setting
determines the length of the 2nd phase of
freezing cycle (controlled by the electronic
timer) as detailed in the table B.
The DIP SWITCH keys 5 & 6 setting determines
the length of the defrost cycle according to the
size of the cubes (Large or Medium) as per the
following setting:
ON
ON : PROGRAM A

OFF : PROGRAM B
OFF OFF : PROGRAM C

The 9th key is used to supply power to the water
pump for the first 15 seconds of the defrost cycle
- position OFF - or for the first 30 seconds -
position ON.
The 10th key is used to modify the CUT-OUT
condensing temperature from 70
°
C (160

the air cooled versions - ON position - to 60
°
C
(140

CLEANING REMIND PC BOARD
Located on the front left side of the machine, it
works in conjuction with the condenser sensor
and the Red Alarm Re-Set Push Button.
It consists of a Printed Circuit Board with a step
down transformer (230V - 12V), a relay, a Dip
Switch with two keys, a Jumper for the set up of
the Cut OFF/Alarm condensing temperature (70
°
C
- jumper OUT - for air cooled version and 60
°
C -
jumper IN - for water cooled version), a green four
contacts connector for power IN and OUT, a Red
socket for the Water Level Sensor (future use on
EC series only), a Black socket for the Condenser
Sensor and a White socket for the Red Alarm Re-
Set Push Button.
The main function of this PC Board is to switch
OFF the machine when the condensing tempera-
ture is higher of its setting value or signal out the
need for the cleaning of the condenser air filter
(air cooled only) or of the water system.
