LED signalling
Symbol Description
LO 1-6 6 orange LEDs for each output
LI 1- 7 7 green LEDs for each input
LE 1-4 4 red LEDs for status/alarm (flashing) stand by
– ice – full - wash
5.3. Alarms
They detect operational malfunctions. They are indicated with the flashing status LEDs LE1-4.
During some alarms a second operation retry attempt is carried out and if repeated again, the
machine will stop. Signaling should be indicated since the first failure occurs. If the second retry
attempt is ok, the signaling must be switched off.
In case that a machine stop has been caused by alarm, the resetting is done by disconnecting
or by switching over to position 0. If the dip-switch 2 ON, time alarms are not to be followed.
5.4. Safety pressure
When the pressure contact (P) is open, instantly, all outputs switch over to off position.
When it is closed again, there are two possibilities:
- Dip-switch 1 OFF. Manual reset. The machine remains stopped until reset

Initial start-up.
- Dip-switch 1 ON. Automatic reset. The machine will stop for a time t5, then continue at the
position where it was, except during the harvesting phase, that has an initial start. If starts at
fabrication, the hot gas valve will open during time t20 before starting the compressor.
* Signaling: Flashing in the four LEDs.
