Do you have the schematics to this controller box? I don’t believe I’m getting power out to the solenoids?Good day
D013:
Disconnection of P1 unload propotional valve.
D022:
Failure of output of transistor ON at P2 unload propotional valve.
D023:
Disconnection of P2 unload propotional valve.
D032:
Failure of output of transistor ON at travel stright propotional valve.
D033:
Disconnection of travel stright propotional valve
Kind regards

the pressure is read by two pressure sensors on on the pump.
if you hold the buzzer stop while turning the key on it will take you to diagnostic screens, scroll through them and look at you solenoids they will have a commanded and measured current in mA see if they are reading the same on the measured side usually means a bad controller but if you need to run the machine go to the control valve and look at the top center there will be two unloader reliefs looks like a nut with a hex stem sticking out . if you back them out 2 turn s the machine will start and operate enough to move it
