A delay defined by parameter
Conf18
triggers the door open alarm, the compressor stops
immediately and the alarm is displayed.
When the door is closed, the alarm is automatically reset.
In models in which a door microswitch is installed also at the conveyor of the cell fans,
the alarm may also be caused by it
Check, during the cycle, that the door remains perfectly closed,
otherwise check the door alignment
Check the value set on parameter
Conf17
(input polarity)
Check that the door microswitch is correctly positioned
Position it correctly, if necessary
If the microswitch is correctly positioned, access the electronic card
With the multimeter set in Ohm, after having disconnected the microswitch from
the terminal board
Make sure there is continuity on the door closed contact.
If not, replace the microswitch
If there is continuity on the closed door microswitch but the alarm remains displayed,
the cause is the faulty digital input of the card. Replace the electronic card
In case of blast chilling cells, check the continuity between the series of ALL the door microswitches
(internal doors and conveyors). If there is continuity on the closed doors/conveyors but the alarm
remains displayed, the cause is the faulty digital input of the card. Replace the electronic card
