Old Sentronic to a new OPS2
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.

Hi Chemi-cool.
prefer the 4 wire connection set up, control switch in and out two wires, power supply from contactor supply and neutral 2 wires. OPswitch activated when contactor is activeted.
