Conveyor Timer “err” display read out

[ectofix]

I’m not up to speed on Middleby’s technology.  Even the old stuff.  Didn’t see many of them in my market.

 

A typical conveyor oven uses magnets super-glued to the shaft of a DC stepper motor and a Hall-effect sensor to sense its rotational speed.

 

Without doing a bunch of reading, I don’t know.  Maybe this manual will help:

Otherwise maybe someone with experience on those ovens can step in.
