CLEAR The CLEAR key is used to acknowledge and clear alarms/failures as well
as to silence the alarm horn.
Use the following steps to acknowledge and clear any alarms & failures.
1. Verify Screen Type - The Alarm & Failure status screen or the Main Status
screen should be displayed.
2. Acknowledging an Alarm or Failure - Press the CLEAR button. When the
CLEAR button is pressed the previously flashing ALARM or FAIL in the lower
right-hand corner of the screen will stop flashing and go to a constant highlight.
This action will also deactivate the alarm or failure discrete output. When multiple
alarms are active the acknowledging function operates on the entire set of active
alarms or failures.
3. Correct Problem -The operator must now correct the problem causing the alarm
or failure. This may be a control parameter that is out of range, or various other
conditions which should be familiar to the operator.
4. Clear Alarm or Failure - Once the problem is rectified press the CLEAR button
on the keypad. The Alarm & Failure status area should become non-highlighted
and display the word NORM, the entry in the active alarm list will also be removed.
The clearing of each alarm is processed when the conditions causing the alarm are
acceptable.
