SETTING UP THE HYDRAULIC SYSTEM
Before beginning the setup procedures for the hydraulics (contactor driven DC pump motor):
• Check that the hydraulic system wiring is consistent with the wiring guidelines presented in
Chapter 2.
• Review the Hydraulics and Controls parameters in Chapter 4, including Figures 28-31
Note: Due to changing device proles, some parameters/variables may be in the CIT List View ( ).
• Conrm that the hydraulic system is consistent with the system diagram shown in either Figure
28 or 29. If it is not, then the following commission guide may not be fully applicable.
• Make sure all electrical and hydraulic connections are tight, and the hydraulic uid lled to the
appropriate level.
• Check that any forks are free to rise and lower. e same applies to any optional hydraulic actuators.
• Turn o the traction interlock while setting up the hydraulic system. If the vehicle is on blocks,
ensure that if the forks are lied and lowered, the vehicle remains stable.
HYDRAULIC LIFT AND LOWER COMMAND INPUTS
Several methods are available to control the hydraulic pump motor and lowering valve(s) comprising
the hydraulic system.
• Li and Lower input switches.
ú Li and Lower commands are single inputs for an On/O operation. See steps 1–8.
ú Li is an On/O operation, yet the Lower is a variable throttle for a proportional valve. See
steps 9–20.
• Individual Li and Lower throttle voltage inputs.
ú Voltage input determines the li or lower operations.
• CAN and/or VCL.
When setting up the hydraulic system, reference Figure 40 (below) for the proportional driver signal
chain. e diagram lists the congurable parameters, VCL function/variables, and the run-time
variables (monitor variables) throughout proportional driver signal chain.
For conguring the load hold valve, reference Figure 41 (below). e diagram lists the signal chain
inputs throughout, the congurable parameters, VCL function/variables, and the run-time variables
(monitor variables).
