View Alarms
screen to view the active faults.
2. Attempt to clear any latching alarms by pressing the checkmark button in the
Main Menu ->

screen. If the alarm persists, it will not clear from the display.
3. Locate the alarm name in Table 4.1.1 on page 4.1.9 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 “Replacement
Procedures” on page 4.1.40 .
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.
NOTE
: Table 4.1.1 on page 4.1.9 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 controller UI (in parentheses). The
Description and Troubleshooting Action
column provides a
brief description of the alarm, troubleshooting tips and a cross-reference to more detailed
troubleshooting, as applicable.
4. If troubleshooting and subsequent replacement of a suspect PWB or module causes the alarm to
disappear from the
View Alarms
screen, the alarm has been successfully cleared. If the fault
condition does not clear, contact Nautel.
