Silencing Horn:
If a horn is sounding and the alarm is silence
able, a quick press of the [SILENCE/LAMP TEST] will silence the
horn (less than 1 second press).
Resetting Alarms:
If the alarm condition has cleared, press and
hold the [RESET/ESC] button 2 to 5 seconds to reset alarms.
“Engine Failed to Start” and “Engine Overspeed” alarms require
the system to be in the OFF mode before a reset is allowed.

When controller is in Auto Mode, pressing and
holding the [TEST] button for two or more seconds will open the
pressure drain solenoid thus dropping the pressure which causes

[TEST] button in Manual Mode will illuminate the lamp on the
button but has no effect on the starting.
Lamp Test:
To illuminate and check all the OID LED’s and the
horn, press and hold the [SILENCE/LAMP TEST] button 5 or
more seconds or until all the lights turn on. The lamps will cycle
on for 2 seconds and off for 2 seconds.
