1. ELECTRONIC BOARD FUNCTIONS
- ice level check with probe
- condensing temperature check with probe (machine stop with temperature > 60°C water version; > of 70°C air).
- Maintenance check. The maintenance alert can be programmed after a certain number of hours of functioning.
- Wash/cleaning cycle check to be carried out periodically with manual control.
2. ELECTRONIC BOARD INPUTS AND OUTPUTS
Condenser probe: with condenser temperature < 24°C, the board makes the fan turn guaranteeing optimal condition of conden-
sation and machine yield.
Condensing temperature probe failure: +70°C air cooling version , +60°C water cooling version.
When the sensor temperature drop below than 10°C under the maximum values (see above) the machine re-start automatically.
In case of 3 errors occur within 6 hours running period, the machine stop definitively.
This mean that there is a serious functional problem.
Resistance values of the temperature probes (deposit probe and condenser probe) with reference to the room temperature:

3. OPERATION CHARACTERISTICS
On the starting the machine goes into defrosting and discharge the water pan.
The production cycle start with two minutes of delay that allow a correct balancing of the refrigeration system and therefore a
good output and a best production.
During the machine operation, at the end of every defrosting , the water load happens with 80 seconds of delay, this to allow the
evaporator subcooling.
When the bin is full of ice, the probe comes in contact with the ice and the electronic card stop the machine only on the end of
defrosting time. This to always have the cubes completely formed and at the same dimensions.
Signalling of alarms for the models air and water version:
-
condenser overheating : the machine goes to alarm and it restart again automatically once that the cause has been remo-
ved and / or the temperature has re-entered in the range of established operation;
-
error of not water feeding: in case of lack of water the machine automatically start again after 60 minutes from the alarm
reset .
4. WASHING CYCLE
Once the machine is started, it is not possible to exit the washing cycle even if the ice maker is switched on and off, as
the electronic keeps the cycle in the memory.
Time of complete washing cycle: 3 hours
The washing / cleaning cycle is formed of: 90 minutes of washing plus 5 rinsing of 15 minutes each.
At the end of the washing cycle the machine automatically start again in cold cycle.
The water level sensor inside the basin works with waters with conductivity between 20 and 1000 micro-siemens per
centimetre.
The water level sensor can be replaced by a microfloat. Connection is the same for both.
If the machine is supplied with softened water (demineralised), float kit installation is recommended (fig. 17)
