18.1 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, on
the front of the Corrigo / E3-DSP.

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. For alarms that have reset the text “Reset” is shown. Acknowledged, still
active or blocked alarms are indicated by 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. The LED is
then lit.
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 user access 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.
