5.4.1 Alarms
The alarm button (pos.1, gure 6) opens the alarm queue. When pressing this button active and
non-acknowledged alarms will be displayed in the menu window. The alarm-LED (pos. 2, gure 6) will ash
if there are non-acknowledged alarms and be on (but not ashing) if the alarms are still active but have
been acknowledged. If there are multiple alarms, use UP/DOWN to move between them. An alarm can be
acknowledged or blocked by using OK and UP/DOWN. To abort and go back to start menu press cancel
and then press LEFT.
See Commissioning record for an overview of possible alarms.
