Can you explain the cylinder as a counterbalance? Is it in a closed loop system?

The cylinder is mechanical, there is no programming involved. When the compressor turns on, it is pressurized and ready to go. There is a relief valve to let air out when necessary.

However, the arm motor is run by a closed PD loop for preset heights.
