4.6.2 Clearing Alarm History
At significant points such as during preventative maintenance, it may be desired to clear the alarm history.
Warning. Alarm history is collected because it can be very helpful in identifying
a problem with the system. The alarm history should never be arbitrarily cleared
by an operator. Only AAST should clear the alarm history after all the alarms
stored in history have been recorded.
To clear the alarm history, perform the following steps:
1. Hold the Esc button until the main screen is displayed.
2. Press Prg and enter the password (0004). Press Enter.
3. Press Down until the cursor is over “System” and press Enter.
4. Press Down until the cursor is over “Initialization” and press Enter.
5. Press Enter until the cursor is over “Delete Alarm Logs”.
6. Press Up or Down until the “no” becomes “yes” and press Enter.
