3.7.19 Clearing Alarm History
At significant points such as during preventative maintenance and after commissioning, 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 Down until the cursor is over “Delete Alarm Logs” and press Enter.
6. Press Up or Down until the “no” becomes “yes” and press Enter.
3.7.20 Enable SNMP (Optional)
SNMP is available on the ASMUC as an optional extra. To enable it, 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 “Serial Ports” and press Enter.
5. Press Down until “SNMP Recipients Config” is displayed across the top.

7. Press Enter to confirm.
