INFORMATION ON ALARMS:
During alarms, the beeper is activated and the display shows the message “ALL xx”.
The alarm message is alternated on the display even when the beeper has been silenced, until
the alarm has been cleared.
Alarm relays remain activated as long as the alarm is displayed.
In the case that more than one alarm has been activated, each one is alternately displayed.
When the beeper is activated, the operator can silence it by pressing the relative push-button,
after which the alarm can be cleared, by pressing the beeper reset button again.
Power failures will not erase current alarms.
