Crown RC5500:
C2.2 not calibrating

Hi guys. I have a unit that doesn't want to calibrate in the c2.2 section. It goes the first stage, but then doesn't go up or down to maintain, but stops and spins the pump motor very weak. Updated software, cleaned the sensor at the right top section of the mast, nothing.

If it is asking you to empty the forks, the load sensor may be broken. Otherwise the valve for the lift cylinder might be weak and not allowing a full flow of hydraulic fluid thru

I have to rekey to get hydro function, but now it doesn't want to even go up. I can tilt so far forward by a bit, go fully back, but it keeps showing to empty forks to begin, but it's way past down to do so. Only goes down but not up.

It needs to be put of free lift to do the calibration. Once it stops does the screen display anything? If not does it allow you to go up or do you have to key cycle to gain hydraulic functions again?
