APPLICATION SETUP/HYDRAULICS — LIFT SETTINGS MENU
e parameters in this menu, for this non-combi controller, do not oer “throttling” of the contactor-
driven DC pump motor. ese parameters are applicable to alternating the response to a 0-100%
VCL input, an analog voltage input, and less so for a typical switch input.

HYDRAULIC OPERATION
is controller does not control the speed of the DC motor driving the hydraulic pump. It closes a
contactor via an assigned driver, which applies full voltage to a DC pump motor in the traditional
method. is controller does control a proportional lowering valve, and, if used, a load hold valve.
Figures 17 and 18 illustrate two typical hydraulic system and their components for the Li and
Lower operations. For other hydraulic operations (e.g., reach, tilt, side-shi, rotate), the vehicle
manufacturer will provide those hydraulic path(s), whose setup/operation follow similar methods.
To control these other hydraulic valves, use VCL programming and the available (spare) coil-drivers,
switch and analog inputs and the available outputs. Use the gures and parameters to match the
application. If throttling a pump motor is required, select the appropriate combination traction and
pump “combi-controller” … for example, the AC F2-C controller.
