Hello,
after I added a hydraulic block I was facing a problem.
The pump is nearly all the time under pressure. The block has a pressure output and I placed it in line like it is described in outer threads.
I think it is some electrical problem, because if I position the down-left knob between the white and the red characters the pump is without a load. If I turn to the white characters (To use the handle for automatic lifting position) the pump is allways with a load.
And when I turn the knob to the red charakters (up/hold/down) the pump is also with a load.
Before we added the block the pump was only with a load when the 3ph was lifting. And now only when the knob is the the middle position...
Anybody an idea???
Today I checked the two solenoids of the 3ph and one get 12V when it is switched for lifting and the other when it is switched for down. Like it should be. Is there a third one because the pump has a load even when the switch is the position for down...
