To reset the Eaton Series I ON 30 40 50 160 alarm system after it was triggered, follow these steps:

1. Acknowledge the alarm. When an alarm becomes active, it is marked as "Unacknowledged" and, if configured, its LED will flash.
2. Use the front panel display or ProView NXG software to view the alarm condition.
3. Press the appropriate button to acknowledge the alarm (typically labeled "Operate" or similar).
4. If a timer is configured, ensure the alarm condition has cleared and the timer has expired.
5. If needed, reset counters by pressing ENTER and then ENTER again to confirm.

Note: Alarm configuration, including timer and LED settings, must be done using software.
