FAULTS/ALARMS
Press <ENTER > to review or edit the following sub-menus.
Line 2 of the display shows the current Faults/Alarms status in real time. For each parameter
monitored, fault status is displayed as one of the following:
• “–” indicates that no fault or alarm exists.
• “+” indicates that a fault exists, and will cause switching in a redundant system.
• Reversed contrast “+” indicates an active alarm.
Unlike faults, alarms do not cause switching to occur. To display labels for individual faults or
alarms, press [ENTER].
Press [
←] or [→] to move the flashing cursor to make the selection. The label for that
Fault/Alarm is then displayed on line 1 of the display. Press [CLEAR] to exit this level of
operation and return to the previous level.
