Alarm handling
If an alarm condition occurs, the red alarm LED on the front panel of units with display or
the alarm LED on a connected display unit will start flashing. The LED will continue to flash
as long as there are unacknowledged alarms.
Alarms are logged in the alarm list. The list shows type of alarm, date and time for the alarm
and the alarm class (A, B or C alarm).
To access the alarm list, press the alarm button, the front panel button with the red button-
top.
If there are multiple alarms, this is indicated by up /
down arrow symbols at the right-hand edge of the
display.
Use the UP and DOWN buttons to access the other
alarms.
At the left end of the bottom display line the alarm status is shown. For active,
unacknowledged alarms the space is blank. Alarms that have been reset will be indicated by
the text Acknowledged. Still active or blocked alarms are indicated by the text
Acknowledged or Blocked.
Alarms are acknowledged by pressing the OK button. You are then given the choice of
acknowledging the alarm or blocking the alarm.
Acknowledged alarms will remain on the alarm list until the alarm input signal resets.
Blocked alarms remain on the alarm list until the alarm has reset and the block has been
removed. New alarms of the same type will not be activated as long as the block remains.
Since blocking alarms can be potentially hazardous, you need a high log on authority to
block alarms.
Class A and B alarms will activate alarm output(s) if these have been configured.
Class C alarms do not activate the alarm output(s).
Class C alarms are removed from the alarm list when the alarm input resets even if the alarm
has not been acknowledged.
