Fault Report Displays--Latched Faults
The latched fault report displays are shown in Figure 16.
Latched faults must be cleared by the operator. These fault
report displays all operate in the same way. When the indicated
fault occurs, the fault report display replaces the current menu
and (if the audio alarm is enabled) the buzzer sounds.
Note
Latched fault circuits are always enabled and cannot be disabled by
the operator.
The user has two options:
•
Disable the buzzer continue in the faulted condition.
•
Clear the fault by pressing Softkey 4 (Reset).
Both the fault latch and the fault report display will clear when
Reset is pressed.
The fault will not reoccur if the fault condition was transient.
If the fault persists, (e.g. the high voltage overvoltage condition
exists each time high voltage is turned) the fault circuit will trip
again.
