Responding to System Alarms
When a system alarm condition exists, an alarm tone sounds and a number flashes in the
Cut display. The generator is disabled until the condition is cleared.
Most system alarms require some action on your part to correct the condition; however,
some are corrected automatically. Use the following table to determine how to correct an
alarm condition.
After correcting the alarm condition, verify that the generator completes the self-test as
described in Chapter 5,
Setup, Tests, and Adjustment
.
