7.3.3 Overload Light is On
Unit is overloaded Remove overload or check CL setting
Unit is switched to high voltage range. Select correct voltage range.
7.3.4 Distorted Output
Power source is grossly overloaded. Reduce load
The crest factor of the load exceeds 3:1 on the low range or
5:1 on the high range.
Reduce load current peaks by reducing load.
7.3.5 Unit Shuts Down after 1-2 Seconds
Output shorted Remove output short
Output grossly overloaded. Remove ove rloa d.
PFC IGBT module failure Have power module serviced
Operating load with too high inrush or start up currents. Consult factory for application advice.
