Comp Air L01 help with wires from air end

HI


I recently bought a broken Comp Air V01 with a seized motor.

I've replaces the motor and all is well except when I removed the air end months ago i forgot where the wires from the air and connect into the pressure switch(or that's where I think they go- it was a few months ago.)

I've run it very briefly to check rotation as I'm wiring 3 phase and all is well and it produces air but can't work out where the two wires go.

When I put a meter across the two mysterious wires from the air end I get about a 3 ohm resistance and can't see where on the pressure switch they would be wired into.

Annoyingly I can't even find a parts manual to even identify the part the wires come from.

I did look at the Hydrovane HV01 manual on here but that machine doesn't seem to have it. ( I thought it was the same machine just rebranded)

I 'm trying to find out before I run it up to full temp just in case its important so the integrity of the machine is still an unknown.

Hmmm. OK, I'm confused, I guess.

Could you get a few pix of this thing and post?

Preferably one overall and any boxes on it, and both ends of the wires in question?

Thanks.

You could be right about it being a temperature switch but there's no where on the pressure switch to attach them.

Its only got the 6 terminals 3 in and 3 out.

The wires don't look thick enough on the temp cable to make a through wired break circuit with a 2.2kw motor.

As I can't find a drawing I don't know if they are superfluous in my set up. (I hoped there might have been a simple over temp control on the pressure switch which made sense in my head.)

Or I'm missing something.

Just a swag - if they come from the air-end, they're probably a temperature sensor, and they'd go to the controller.

Ring any bells? (I haven't looked up the machine yet).
