Issue 3.4 2016-08-03 Page 2-67
Viewing alarm details
The Transmitter Status page - see Figure 2.40 on page 2-66 displays a table that lists the active
alarm details under the following columns:
•
Device
- identifies the alarms by their originating device (e.g., Controller, Exciter A,
etc.)
•
Alarm
- identifies the type of alarm (alarm name).
•
Level
- identifies the severity level of the alarm.
Status button colour indications
• When the
Status
button is red, one or more active alarms are indicating that the trans-
mitter may be in an ‘off-air’ state.
• When the
Status
button is amber, one or more active alarms are indicating that the
transmitter is still ‘on-air’, but may be at reduced power.
• When the
Status
button is green, no alarms are being reported and the transmitter is
operating normally.
Resetting alarms
When an alarm is present, use the
Reset
button, at the bottom of any AUI screen, (see
Figure 2.41 ) to clear any latching alarms that are holding the transmitter in an “off-air” state. If
the offending alarm has cleared, then the transmitter should resume operation.
Note:
When viewing alarms, cross reference the alarm name, (which appears in the
Alarm column of the Transmitter Status page) with Table 1.1 of the
Troubleshooting Manual.
