Hydrovane HV 02 - need a wiring diagram

I'm installing a new motor and starter and pressure switch on a Hydrovane HV 02. 3ph 50Hz. I believe I need a wiring diagram. Can't find one at Gardner Denver site. Can you help? Thanks Steve

Hydrovane HV 02 temp sensor

Unless it's something really strange, no polarity problem with it. It's just a resistor.

But you can confirm by using a VOM. It should read the same resistance in either direction, and change with temperature change.

HV 02 wiring diagram

Thanks for the comments and diagram. Now I'm specifically wondering if there is any polarity issue with the compressor end temp. sensor. (I assume no). I have 50Hz, 400v from mains bus. Frequency and voltage conversion is made at mains source (by A Sea) for entire European built ship.

Hydrovane HV 02 - correction
by: Doug in s.d.ca.

Sorry, your starter is the contactor.

Your pressure switch goes in series with the coil on the contactor and one phase of the power, so it energizes the contactor when the motor should start.

It should be pretty straightforward.

Google my comment title for drawings. Your pressure switch should have three sets of contacts and corresponds to "contactor" in some of the drawings you'll see.

Do you have a 50HZ power supply for it?
