Acknowledged and blocked alarms

  1. Press the [OK] button to call up a menu with the available alarm actions for the currently displayed alarm.
  2. Use the [▼] and [▲] buttons to select the desired alarm action.
  3. Press the [OK] button to carry out the action.

The alarm status is shown at the left end of the lower display line. The field is empty for active, unacknowledged alarms. Alarms that have been reset are indicated by the text Acknowledged. Active or blocked alarms are indicated by the text Acknowledged or Blocked.

Acknowledged alarms remain in the alarm list until the alarm input signal is reset.

Blocked alarms remain in the alarm list until the alarm has been reset and the block has been cancelled. New alarms of the same type are not activated as long as the block is in place.
