Diagnostic LED Indicators
The switch can be easily monitored through panel indicators to assist in
identifying problems, which describes common problems you may encounter
and where you can find possible solutions.
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with power outlet, or power cord. However, if the switch
powers off after running for a period of time, check for loose power
connections, power losses or surges at the power outlet. If you still cannot
resolve the problem, contact your local dealer for assistance.
