18000 SERIVCE/MAINTENANCE MANUAL INTRODUCTION
1
When drum control handle is moved to neutral position,
node-1 controller compensates for hydraulic system leakage
or changing engine speed. Node-3 controller sends a zero
output voltage to each pump EDC that moves swashplate to
center position. This shifts the motor back to maximum
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-10. 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 2/5 drum motor remain
open until mast hoist control handle is selected for operating
mast hoist in Setup mode.
