Don't change it then!

@Phil, it comes back to me now, I wanted to turn it on only while a program was running....

Maybe that’s why I’m confused. I thought that’s what it does currently?!

Getting there. Need to get the door on and wire up the other 24V supply.

Outstanding questions:

Ohmic probe wires routed along other inputs and 22 gauge. Concerns?

No concerns if they are properly shielded. Shielding should be grounded only on the electronics side.

Does the 390k or 24k resistor get hot or just warm? Both resistors are sitting in air not touching anything.

I'm not sure so I just kept mine off the circuit board I mounted them to. I used 5 smaller resistors cos thats all I could get locally.
