CCO solenoids are design for battery voltage application within the voltage range in the table above, in
consideration of a wide range of environmental temperature common for known hydraulic applications.
Closed loop PWM current supply can be also applied and is helpful in case that the voltage range is
exceeded, or ambient temperature could rise in an unusual manner.

Caution
It is not recommended to use brake port for any external flow consumption to avoid malfunction of CCO
function.
Displacement limiter
All pumps are designed with optional mechanical displacement (stroke) limiters factory set to max.
displacement.
The maximum displacement of the pump can be set independently for forward and reverse using the
two adjustment screws to mechanically limit the travel of the servo piston. Adjustment procedures are
found in the Service Manual. Adjustments under operating conditions may cause leakage. The
adjustment screw can be completely removed from the threaded bore if backed out to far.
