Sequence of Operation - LINE-IN, Y46F
Activating
LINE-IN
commands the tractor ripper valve to
send oil fl owing to the winch, through the counterbalance
relief manifold and to the motor “A” port. At the same time,
high pressure from the CBR manifold applies pressure to
the RI port, through the shuttle valve, to the brake valve.
The brake valve directs pilot fl ow to release the brake.
If the operator selects
HI-SPEED
mode, an electric
solenoid valve on the control manifold sends pilot pressure
to the C port on the motor. The spool shifts to close half of
the power cavities in the motor. Full pump fl ow now fl ows
through the motor at half displacement, thus doubling the
output rpm.
If the winch is pulling a load, the pressure at a pressure
switch on the CBR manifold will increase. When pulling a
heavy load, the pressure switch, which is normally closed,
will open. This will disable
HI-SPEED
mode, forcing the
motor to maximum displacement (low speed, high torque)
ensuring that the winch can pull the load.
