CAN Bus Communication Port

•

Smooth Control of Hydraulic Functions

•

This option allows control and access of all control and status

functions through a standard two wire connection. Man-up

vehicles can simplify wiring, improve reliability and reduce

cost. Complex vehicles can connect multiple modules and

share features and functions.

Pulse-Width Modulation controlled pump motor provides

smooth start-up and rampdown on each function. Precise

current and voltage control eliminates the bumps and jumps

associated with on/off contactor control for increased

efficiency and reduced contactor tip and motor brush wear.

Load Compensation automatically varies the applied motor

power in response to changes in weight and forces on the pump.

Provides better speed regulation empty verses loaded, when

picking up mast sections or while multiple functions are engaged.

A current regulated proportional valve driver provides

controlled, continuously variable speed lowering. An additional

solenoid driver is provided for load hold or flow control.
