rthirlby Posted November 5, 2006 Report Share Posted November 5, 2006 We have long since lost the manual for the delta4 that runs some of our house lighting. The dimmers are not going off properly at zero control volts. Is the unit trimmable? I can see one single pot on the pcb but have not yet plucked up courage to adjust it. :?: Rob Thirlby, Little theatre Dover street leicester LE1 6PW Quote Link to comment Share on other sites More sharing options...
KWR88 Posted November 6, 2006 Report Share Posted November 6, 2006 That is the trim pot but the problem may indiacte that a fault has developed with circuit, as these pots do not tend to move much once they are set. I will PM you with some possible faults. Quote Regards, Keith Rogers Zero 88 Support: support@zero88.com Link to comment Share on other sites More sharing options...
rthirlby Posted November 7, 2006 Author Report Share Posted November 7, 2006 Many thanks for your help. I successfully trimmed the dimmers using the pot. It was generating 25volts ac for zero control voltage. It will be interesting to see if it wanders off again. if it does then I will replace the unit.
