5.0 Diagnostics
5.1IndicatorLights
The unit contains 3 indicator lights on the front panel and a remote alarm relay.
5.1.1GreenLight
Condition normal. The remote alarm relay is open.
5.1.2MiddleAmberLight
A transformer over-temperature has been detected. The output voltage is not
regulated under this condition in order to minimize transformer losses. The
remote alarm relay is closed. In order to reset this condition, the unit must be
turned off, allowed to return to normal temperature, and then turned back on.
Check to ensure the load kVA does not exceed the nameplate kVA. Make sure
the ambient temperature does not exceed 40°C.
