CONFIGURATION: CONTROLS
Manual Displacement Control
The Standard Displacement Control provides a pump
output flow (displacement), in either direction, that is
approximately proportional to the angular movement of the
control handle. The control will return to neutral if the
control handle is released. The internal centering
mechanism is not sufficient to overcome external
control linkage friction.
This control has an orifice for controlling maximum
acceleration or deceleration (control response). The orifice
is available in various sizes for matching the control to the
system.
CAUTION
Torque on the Control handle shaft must not exceed 150 in.
lbs.
Manual Displacement Control With Pressure Override
A Pressure Override can be added to the Standard
Displacement Control to provide overload protection. This
override will automatically destroke the pump once the
desired maximum system pressure (load) is reached It will
maintain that system pressure so the load can be held This
prevents operation of the system relief valves for
prolonged periods and helps reduce heat build up in the
transmission.
Neutral Start Switch
A Manual Displacement Control is available with a Neutral
Start Switch which can be used to help insure that the
prime mover is started only when the control is in neutral
(O flow) position. The switch provides an electrical
interrupt of the starting circuit unless the control is
positioned in neutral.
Hydraulic Displacement Control
A Hydraulic Displacement Control is available which
provides a pump output flow (displacement), in either
direction, that is approximately proportional to an input
pressure signal. This control is not available with a
pressure override feature
The Hydraulic Displacement Control also has an orifice
(different
sizes
available)
for
controlling
maximum
acceleration or deceleration. A displacement indicator is
an optional feature on this control.
