Al working fine but the channel 3 goes out.... What is the pin out and voltages should be read on the opit transistor IC???





Thanks

I measured voltages around the opto's the other day.

On the low voltage side only one pin goes to approx 0.3 volts when the channel should lit. (Reference: Header, Gnd)

On the high power side there is permanent mains voltage on 2 pins and on the third when the channel should lit. (Reference: Neutral)

Sorry, but i cant remember the pin numbers.

Datasheet: http://www.alldatasheet.com/datasheet-pdf/pdf/27238/TI/MOC3023.html

I used Hardware utility to turn on 2 channels and then used the working channel to compare.

Hope that helps. Good luck.

I rest the unit by putting jumper on J0 and the re freshed the fireware then it worked again. YEAH!!!!!!!!! Learning something new each day..
