VAC IN on the AC input modules, VDC IN on the DC input modules and VCC on both output modules

Can you see the MCA output change from 0 to 1? If so, can you pull the field wire from MCA where the thermal overload is or would be to see if MCAI go...

I think you mean PA3 board. You might check the ELI parameter under System > Adjust (Electronic Limit Interface). It should be set to 0 to use the ...

Nice work! Thanks for the update.

And these are wired like this:

I should warn you, these are not very exciting.

There are several of these used to pick relays. From a quick look at a TIV print these relays are all picked with an AC output module: S, BK2, BK3, CD...

Maybe but I did try it with a relay too. I did take a little video of all 4 variations working if you're interested.

Correction: the input module circuits should look like this. I wired up all 4 variations today. The input modules switch the - not the +. The DC outpu...

I would 2nd that. By a mile the most common cause of any up issues in an I-2 or I-3 valve. Always have a spare and clear O-Rings, replace the O-rings ...

There are no relay contacts in the valve coil circuit on a TAC32 and it monitors that there is voltage on the coil.

I ask because the 1043 is the standard low oil shutdown but I have had problems with the Z44 adjustment causing 1123 Up run stalled faults. Sticky pac...

What fault code specifically is it getting?

Inputs look right but I think the outputs should look more like this:
