Old Sentronic to a new OPS2

[chemi-cool]

25 hp Copeland compressor, trips on oil pressure control.
Sensor does not work. Checked the oil pressure - 120psi, fine by me.
Only controller supplier had was the OPS2.
Wiring is different and it has 6 wires instead of the Sentronic.

Any one have done such a change? I would like to hear about it.

Thanks.
