FCM 300 Series
Wherever a X is placed under both Warning and
Alarm, this can mean that a warning precedes the
alarm. It can also mean that it is possible to
program whether a given fault is to result in a
warning or an alarm. After a trip, alarm and warning
will flash, but if the fault is removed, only alarm will
flash. After a reset, the FCM 300 will be ready to
start operation again.
