Sequence of Operation - LINE-OUT, Y46F
LINE-OUT
operation is similar to
LINE-IN
except
LINE-
OUT
reverses fl ow at the tractor ripper valve and directs
fl ow through the counterbalance relief manifold to the motor
“B” port and to the RO port on the control manifold, and
returns through “A” port. Brake release operates the same
as
LINE-IN
mode.
In
LINE-OUT
operation, oil fl owing from motor port “A”
to the counterbalance relief manifold is controlled by the
counterbalance valve. The counterbalance valve maintains
suffi cient pressure in the motor outlet (A) line to prevent
uncontrolled lowering of a load.
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.
HI-SPEED must be disabled during LINE-OUT
if there is a load attached to the wire rope.
