I wanted to get this up and running today and here's where I am at:
new controller
old controller
The thermocouple is obvious.
Blue wire went to N.O. on old board, so went to N.O on new RELAY 1.
Black wire went to L1 on the old board which is one terminal on the transformer, and this was bridged to C, as you can see in the pic. So I plugged this into COM on RELAY 1.
White wire went to L2, the other terminal on the transformer on the old board.
Big question: Where would the white wire go?
Second question: should I run power lines from the strip to the new controller? I would just bridge the conveyor belt motor strip terminals to the power connection on the controller.
Thoughts? Really don't want to melt $280.
