msbreton Posted November 19, 2008 Share Posted November 19, 2008 I'm trying to trigger a Definite Purpose Contactor via one of my channels on a 16 unit controller. Turning the channel on, triggers the Definite Purpose Contactor correctly but when I turn off the channel, the Definite Purpose Contactor never turns off.I started to measure voltage on the LOR1602W unit and found it to not be 120v when on (it was about 88 volts) and to remain at ~16 volts when off. The fact that it is still putting out 16 volts when "off" is why the Definite Purpose Contactor is not powering down.I tested another LOR1602W and found it to do the same thing.Any ideas why the LOR1602W doesn't output 120v per channel when on 100% and why is doesn't output 0v when off?Unless I can resolve this, my plan to control my "snow" machine is in big trouble.Thanks!

-klb- Posted November 19, 2008 Share Posted November 19, 2008 Try adding a bit more load to the channel. A C9 bulb or similar... - Kevin Link to comment Share on other sites More sharing options...
msbreton Posted November 20, 2008 Author Share Posted November 20, 2008 Thanks for the suggestion.Adding an additional load to the channel that is triggering the Definite Purpose Contractor solved the issue!!!!!Whew! Link to comment Share on other sites More sharing options...
Guest wbottomley Posted November 20, 2008 Share Posted November 20, 2008 The triac's react better to a resistive load (light bulb) better than an inductive load (contact, relay, motor).Sometimes placing that night light on a channel, helps things work better.
