Product overview

Theory of operation
Electric proportional control M1XX, M2XX, K1XX, K2XX
The electric proportional control consists of a proportional solenoid driving three-way porting spool.When activated, the spool ports high pressure to the larger diameter of the servo piston. The servo pistonand rotating group move to change the displacement to the point where the pressures on the servo arein balance with the force from the feedback spring.• Solenoid de-energized = minimum displacement
• Solenoid full-energized = maximum displacement
Pressure Compensator Override (PCOR)
The de-energized electric control keeps the motor at minimum displacement. The electric control can beoverridden by the PCOR using high loop system pressure. When the system pressure rises above thePCOR setting, the PCOR activates. The motor then increases to maximum displacement. The motordisplacement is regulated automatically between minimum and maximum in response to the high looppressure. This ensures optimal power throughout the entire displacement range of the motor.
Pressure Compensator Configuration
KXK1, KXK2 with electric Brake Pressure Defeat (BPD)
For propel applications, use the electric BPD option in conjunction with the PCOR option. The BPD shuttlevalve is ahead of the pressure compensator control valve. The BPD consists of an electric off/on solenoidand a two-position, three-way porting spool. The applied logic allows the pressure compensator controlto operate normally with system pressure during acceleration and cuts off the supply pressure duringdeceleration or overrun. This prevents rapid or uncontrolled deceleration while the machine is slowingdown. With the BPD solenoid de-energized, the porting spool is centered by spring force. A directionlever switch or an output signal from a microcontroller must control the BPD solenoid.
KXKA, without Brake Pressure Defeat
This option has PCOR function but no BPD function.
MXCA, without Brake Pressure Defeat
This option has no PCOR function or BPD function.
