Cat EC25EN2 Error Code 47

I am having an issue with our Cat. Power on key switch the pump runs as normal. I can move the unit forward reverse/power steering works. But as soon as I touch any hydraulic lever the contactor kicks out and throws error code 47.
I can get on and off while it is power on and the lift symbol goes on and off so it appears that the seat safety switch is working correctly.
I have a manual on the way to trace wires. Is there some type of other safety switch that kills the power to the contactor?

Does the power steering work off the lift pump? That works normally.

Error code 47 is referring to pump motor is opening this happened if
1-faulty pump motor or its wires.
2- faulty pump inverter or its wires
3- faulty logic unit power supply card.
