List of current alarms
If an alarm exists and is currently being recognized by the transmitter system, it is displayed in the
Alarms
screen of the front panel
Display
(see Figure 1.3 ). The prefix of the alarm name indicates the
sub-system origin of the alarm. For example, alarm names prefixed with “TXA” or “TXB” are part of
transmitter A or B, respectively. Alarm names with “Sys Con” or no prefix are system alarms.
Figure 1.3: Alarms Screen
Table 1.1 on page 1-7 contains a column for most
Alarms
that can occur, sorted alphanumerically by
system controller generated faults and transmitter generated faults. The
Alarm/Status LED
column
indcates the associated front panel LED affected by the alarm. The
Description and
Troubleshooting Action
column provides a brief description of the alarm, troubleshooting tips and a
cross-reference to more detailed troubleshooting, if applicable.
1. Scroll through the
Alarms
screen to view the active faults.
2. Enter the alarm name in Table 1.1 on page 1-7 to determine the cause of the alarm and
perform any recommended troubleshooting procedures.
3. If troubleshooting and subsequent replacement of a suspect PWB or module causes the
alarm to disappear from the
Alarms
screen, the alarm has been succesfully cleared.
4. If troubleshooting and subsequent replacement of a suspect PWB or module does not
remove the fault condition, contact Nautel.
NOTE:
Before undertaking any troubleshooting, record all Display meter readings and note if any other
alarms are displayed on the
