3. Locate the alarm name in Table 1.1 on page 1-9 to determine the cause of the alarm and
perform any recommended procedures in the
Description and Troubleshooting Action
column. This may also lead to replacing a suspect PWB, power supply or fan, as detailed in
“Replacing a suspect PWB, power supply or fan” on page 1-31 .
4. Refer also to Table 1.2 on page 1-25 for Summary alarms that can occur - when properly
configured - as remotely monitored outputs.
5. If troubleshooting and subsequent replacement of a suspect PWB or module causes the
alarm to disappear from the
Transmitter Status
page, the alarm has been successfully
cleared. If the fault condition does not clear, contact Nautel.
NOTE:
Before undertaking any troubleshooting, record all meter readings and note if any other alarms are
displayed on the
View Alarms
page
.
Record all alarms. Use the remote AUI’s Critical Parameters
page (Menu -> User Settings) to Capture Meters and Capture Alarms, which copies meter readings
and active alarms into a spreadsheet for future reference.
NOTE:
Table 1.1 on page 1-9 contains a column for most
Alarms
that can occur, sorted alphanumerically
for each sub-system, including both the names displayed on the AUI and, if different, the front panel
UI (in parentheses).
The
Description and Troubleshooting Action
column provides a description of the alarm,
troubleshooting tips and a link to detailed troubleshooting, as applicable.
NOTE:
Table 1.2 lists the Summary alarms that can be configured for remote monitoring through the
remote AUI’s Menu ->Remote I/O -> Remote Outputs page (see the “Operating the
Transmitter” section of the Operations & Maintenance Manual for configuration details).
Each Summary alarm can be triggered by any one alarm in a specific sub-set, as shown in
Table 1.2 . The Description and Trigger Alarms column of Table 1.2 provides a brief
description of the summary alarm and a list of the triggering alarms. To determine the root
cause(s) of a Summary Alarm, check the remote AUI for an offending trigger alarm and refer
to its troubleshooting information in
Table 1.1 on page 1-9 for more details.
