Rotary Carriage Downfeed Creeps

Diagnosis & fix steps

LOGIC: Crowd System Counterbalance Holding Valve Pilot Solenoid Short to Power. ACTION: Measure resistance across holding valve solenoid on the crowd cylinder manifold. Check harness loom running down the mast lattice for 24V shorts from auxiliary lighting cables.

Red Seal field insights

Mast Drop Protection: A shorted line prevents counterbalance logic from locking fluid in cylinder cap ends, allowing the heavy rotary top-drive to drift down under its own weight.
