FUNCTION SELECT
FAULTS/ALARMS
Press to review or edit the following sub-menus.
The Faults/Alarms level is accessible from the Function Select: menu. These are similar
to monitor functions, as the current status is displayed.
Press [
←] or [→] to move between the Fault/Alarm groups:
• Demodulator faults
• Receive Interface faults
• Common Equipment faults
The current Faults/Alarms status is displayed on line 2 of the display in real time.
Fault status is displayed as a “+” (plus) or “-” (minus) for each parameter monitored:
• “-” indicates that no fault or alarm exists.
• “+” indicates that a fault exists, and will cause switching in a redundant system.
• A reversed-contrast “+” sign appearing on the display indicates an alarm is
active.
Note: 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 the fault or alarm to be identified. The label for that
fault/alarm is immediately displayed on line 1 of the display.
To exit this level of operation and return to the previous level, press [CLEAR].
