Diagnosing Switch Indicators

This switch can be easily monitored through panel indicators to identify
problems. The table below describes common problems you may
encounter and possible solutions

Table A-1 Diagnosing Switch Indicators

Symptom

Possible Cause

Action

Power Module

-48 VDCor AC

Power outlet,

power cord, or

power module may

be defective.

• If using a DC power

conversion module, check the
connections between the
switch and the external DC
power supply. If using an AC
power module, check
connections between the
switch, the power cord, and
the wall outlet.

• Contact your dealer for

assistance.
