serious alarms:
in the configuration with two alarm relays, these activate the alarm output; the other alarms, ON the
other hand, activate the dehumidification.
In the event of an alarm, the machine performs the following
actions:
• activates the buzzer and display
, (if enabled and machine
ON);
• activates the alarm relay (according to parameters HF,
HA);
• displays the alarm code and switches on the corresponding
red LED.
In this condition, pressing the alarm button silences the buzzer.
The termination of alarms with automatic reset, if no alarms
with manual reset are active, brings about:
• the switching off of the buzzer;
• the deactivation of the alarm relay, see parameter HF;
• the switching off of the red alarm LED;
• the re-activation of the actuators switched off by the alarm.
Pressing the and buttons together for 2 seconds cancels
the display of the alarm codes. In the event of alarms with
manual reset, pressing the and buttons together for 2
seconds brings about:
• the deactivation of the alarm relay, see parameter HF;
• the switching off of the red alarm LED;
• the re-activation of the actuators switched off by the alarm.
The maintenance signals for compressors 1 and/or 2, the
fan and the filter, due to the exceeding of the hour counter
thresholds, activate the symbol
on the display, the red
LED, the buzzer and the alarm relay. The alarm messages are
shown cyclically in the order indicated in the following table.
On termination, the display of the percentage of humidity (if
present) returns for 6 seconds.
