displacement for slower output speed to slow the drum
rotation. Node-1 controller stores the load holding pressure
in pressure memory.
After control handle center switch opens, node-6 controller
sends a zero output voltage to disable drum brake solenoid
valve HS-7. Drum brake solenoid valve shifts to block pilot
pressure to brakes and opens a line to tank. Brakes apply
before drum pump de-strokes.
The diverting valve lines to main hoist 1/3 drum motor remain
open until whip line hoist control handle is selected for
operating whip line hoist in any mode.
