Setting up the hydraulic system
Before beginning the setup procedures for the hydraulics,
• Double-check the hydraulic system wiring to ensure it is con-
sistent with the wiring guidelines presented in Section 2.
• Confirm that the hydraulic system is consistent with with
the system diagram shown in either Figure 15 or 16.
• Make sure all electrical and hydraulic connections are tight,
and the hydraulic fluid filled to the appropriate level.
H
-1 Hydraulic throttle inputs (see pages 50–54)
For simple digital (on/off) inputs using the Lift and Lower switches, set the Lift
Switch Only Enable and/or Lower Switch Only Enable parameters to On. If
both are set On, the hydraulic throttle is not used and the Hyd Throttle Type
should be set to 5.
For variable lift or lower, the hydraulic throttle must be set up. Still with
the interlock verified to be off, the Hyd Throttle Type must be set up to match
the type of throttle (1–5) and wiring that you are using, as described in the
Hydraulic Throttle menu and on pages 11–15.
Adjust the Lift Deadband, Lift Max, Lower Deadband and Lower Max
parameters to match the range of your hydraulic throttle. The Pot2 Raw value
displayed on the Monitor
» Inputs menu (page 64) is useful when setting up
these parameters. For lift and lower, read the displayed Pot2 Raw voltage at
the point when the throttle moves out of neutral and at the point just before
full throttle and enter these values for the deadband and max settings for that
direction. Set up the other parameters in the Hydraulic Throttle menu as re
-
quired by the application.
You will be able to verify that your hydraulic throttle settings are correct
by checking the Mapped Hyd Throttle value displayed in the Monitor
» Inputs
menu (page 64) over the entire range of throttle movement. The value displayed
for Mapped Hyd Throttle should be = 0% through the range of throttle mo
-
tion that is considered neutral. The displayed Mapped Hyd Throttle should be
= 100% through the range of motion that is considered Lift throttle max and
should be = -100% through the range considered Lower throttle max. Contact
your Curtis customer support engineer to resolve any issues about the throttle
setup before continuing with the setup procedure
.
H
-2 Load hold valve (see page 51)
If your application uses a hydraulic load hold valve, set the Load Hold Enable
parameter On; otherwise set it Off.
H
-3 Proportional lowering valve (see page 46)
If your application uses a proportional lowering valve, set the PD Max Current,
PD Min Current, PD Dither %, and PD Dither Period parameters based on
the valve manufacturer’s ratings.
