Alarm Override
If your system is connected to an external alarm, the alarm will turn on when
an error is detected. An uncleared error code will cause the alarm to be on
until the problem is solved.
Press the Nordson key to override the alarm for 10 minutes. The alarm will
turn on again in 10 minutes if the problem is not solved. If a new alarm
condition occurs within the original 10-minute period, the alarm will turn on
again. You may continue to press the Nordson key to override the alarm
and allow the system to operate until the problem is solved.
