Adjustment of Working Temperatures:
(Figure B: Diagram of Electronic Board)
Temperatures are factory-set at:
·55ºC for the wash tank
·87ºC for the boiler
Temperature Adjustment:
In order to be able to adjust the tub and boiler
temperatures, the two microswitches must be in
the OFF position (Elements Disconnect: OFF).
This way, the two elements remain live and
temperatures can be adjusted within the
permissible range: 40 to 70ºC for the tub and
170 to 95ºC for the boiler. Adjusting procedure:
· Check that the two elements are on:
microswitches (3) in the lower position:
"Elements Disconnect: OFF".
·Press the red key (Fig. B-5) during 3 seconds
to activate the temperature setting function.
·The display shows the temperature then
predefined for the tub or the boiler (depending
on how many times you pressed the key - Fig.
A-3).
·To adjust the temperature, there are two
potentiometers: B-2 for the tub and B-4 for the
boiler (both clearly identified on the silk-
screened
board,
that
also
temperature ranges).
·Adjusting is done by turning the relevant
potentiometer clockwise to increase the
temperature and counterclockwise to decrease
it; the display showing the tub or boiler
temperature, whichever has been selected with
key (Fig. A-3).
·After setting the required temperature, power
the machine down and up with main switch A-1.
As a result, the new temperature is stored in the
memory of the electronic board.
Disconnecting the elements:
In order to disable the heating of the elements,
there are two microswitches (3) on the board.
So, placing the two microswitches in the ON
position will disconnect the two elements
(Elements Disconnect: ON).
Model Configuration:
Control of cycle time (Thermal Lock) as a
function of the boiler temperature:
·The electronic controller features the possibility
of increasing the cycle time until the preset
temperature is reached in the boiler. So, in the
event the temperature of the boiler were lower
than the preset value, the cycle would be
extended until the preset temperature is
reached. This prevents rinsing with cold water.

is turned on. In order to select another
configuration number, proceed as follows:

1.Power the machine down.
2.Move the two microswitches (Fig B-3) to the
ON position.
3.Power the machine up.
4.Press key (Fig B-5): the configuration number
is displayed.
5.Press "Start" (Fig A-5) to increment the
configuration number.
6.Press "Drain" (Fig A-7) to decrement the
configuration number.
7.After selecting the number required, press the
Cycle Selection key (Fig A-4) to confirm.
8.Power the machine down.
9.Move the two microswitches (Fig B-3) to the
OFF position.
10.Power the machine up: the selected
configuration number appears on the display.
Troubleshooting:
Only qualified technicians may work on the
connections of the electronic board, after
cutting out power to the machine with the main
switch and the automatic safety circuit-breaker
at the external feeding point to the machine.
The display shows the temperature probes

·E1:.......Boiler probe disconnected (circuit
open). Check the connections at the connector

The temperature transmitters are connected to
the four-pin connector (Fig. B-c).
·E8:........Break-tank fillling failure, 60 seconds
after completion of rinsing, due to a failure of
the inlet solenoid failure, interruption of water
supply, or failure of the level switch.
·E9:........One or more level switches still on 15
seconds after the beginning of a rinse cycle.
This denotes a possible failure of the pressure
pump that does not supply rinsing water or a
failure of a level switch that does not break.
Verifying the keypad:
To verify that the keypad is working correctly
every time you press a button the LEDs that are
on will blink once. If they do not blink when you
press a button, there is a problem with the
keypad or with the connection between the
keypad and the electronic board.
On the electronic board, there are several light
indicators which are very useful for monitoring
the machine operation and malfunction. Those
indicators belong to either of two groups: input
LEDs or output LEDs.
Input LEDs: those associated with information
received by the electronic board. Their location
and description are indicated on the silk-
screened board and on Figure B. The following
are amber LEDs:
·'DOOR' LED: ON, when the door is closed.
·'HIGH PRES.' LED: ON, when the high
pressure switch is on, meaning that the tub is
full.
·'LOW PRES.' LED: ON, when the low
pressure switch is on, meaning that the water
level has reached the bottom pressure switch.
·Reserve LED: associated to a spare input.
·'HIGH FLOAT' LED: Break Tank High Float
LED. ON, when the high float has been
actuated, meaning there is water up to this
