SpectraLight QC displaying the Daylight Overload Error Message.Day Light Overload error message is cause by a higher current draw (load) than expected. The normal current load is 6.2 amps +/-. The overload condition in this case is triggered by a load of 8.2 amps +/- which was caused by having one 500 watt lamp and one 750 watt SPLIII lamp. Make sure that 500W lamps are installed in the SPLQC not the 750W lamps that are used in the SPLI,SPLII and SPLIII.
