NX50 Troubleshooting Manual Responding to alarms
Issue 6.0 2019-04-01 Page 1-7
Troubleshooting an alarm
Troubleshoot an alarm as follows:
1. Attempt to clear any latching alarms by pressing the
Reset
button on the bottom
banner of the AUI. If the alarm persists, it will not be cleared from the display.
2. Locate the alarm name in Table 1.1 on page 1-8 (sorted alphanumerically for each sub-
system) 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 Table 1.3 on page 1-41 .
3. Refer also to Table 1.2 on page 1-36 for Summary alarms that can occur - when
properly configured - as remotely monitored outputs.
4. If troubleshooting and subsequent replacement of a suspect PWB or module causes the
alarm to disappear, the alarm has been successfully cleared. If the fault condition does
not clear contact Nautel Customer Service for assistance.
NOTE:
Before undertaking any troubleshooting, record all AUI meter readings and note
if any other alarms are displayed on the
Transmitter Status
page
.
Record all
alarms. The most convenient way to do this is by using a web browser over a
LAN connection to copy the Critical Parameters. Go to Menu, User Settings and
select Critical Parameters. Select Capture Meters button followed by Copy Meters
button and paste into a spreadsheet or word file for later viewing if necessary.
Capture alarms in the same manner - Capture Alarms followed by Copy Alarms
and paste into file.
NOTE:
Table 1.2 lists the Summary alarms that can be configured for remote
monitoring through the local or remote AUI’s Remote I/O -> Remote Outputs
menu (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 local or remote AUI for an offending
trigger alarm and refer to its troubleshooting information for more details.
