Troubleshooting

That would make sense. So the switch or button after the fuse on the top left is the "OFF" which should be normally closed even though it's marked normally open. The button above the C contacts is the "ON" which should be normally open but isn't marked. Both are momentary.

Or is the switch or button after the fuse on the top left something else and you use the EMO or that switch after it to turn it off???

And that's PB2 (push button 2) not P32 for the oil pump.

Question is why are they drawn with symbols that are more commonly used for limit switches, and shown as normally closed?. Even that PB2 is shown as normally closed when it is likely normally open if it is a push button operator. Unless you are supposed to hold the switch while using oil pump, it probably is a selector or other maintained type of switch.

Whoever did that drawing didn't really know what they were doing. If the switches were at least labeled with their functions somewhere we could have figured this out much sooner instead of guessing. Using proper symbols would have gone a long way also.
