For electrohydraulic Selective Control Valves (SCV), use the Dan-
foss settings during setup. The SCV uses a reference voltage from
the tractor, whereas Danfoss uses a reference from the valve power
circuit. A special SCV valve cable is required for this functionality.
Danfoss Ratio-Metric - when this mode is selected, EG Series
sets up the internal Valve Circuit to generate the proper signals
to drive the Danfoss Ratio-Metric valve. Refer to the wiring
diagram for the proper wire connections.
Valve Type- This setting will default to Push-Pull for the
way the valve circuit has been reconfigured for the Danfoss
Ratio-Metric setting.
Valve Drive Current Limit - There is no need for Current Limit
for the Danfoss Ratio-Metric, the Current Limit will automatical-
ly come up “Not Available”.
CAUTION:
THE FOLLOWING ITEMS WILL OPERATE THE
VALVE DRIVE. BE CAREFUL WITH THEIR USE! MAKE
SURE YOUR AREA IS CLEAR.
Minimum DC - EG Series needs information about the hy-
draulic system on your machine, as all hydraulic systems
are not the same. Here we are telling the system the signal
needed to move the cylinder at its slowest speed. Pressing
the Power (Test) soft key will enter you in to this routine. Your
hydraulics will begin to move, use the Up/Dwn buttons to in-
crease or decrease the signal to the valve until you get a blade
movement of approximately 0.25 inches per second (1 inch
in 4 Seconds). Press the Power Chg Dir soft key to change
the direction, then adjust the cylinder speed for the opposite
direction. When the cylinder speed is OK then press the Menu
(Stop) soft key and these values will be stored. There may be
a need to enter different values for up and down to balance the
over all minimum speed. This is due to gravity helping in the
downward direction and the volume differences in the cylinder,
from the cap end to rod end.
Note that either the “Stop” soft key, or the Menu button will
turn off the valve drive, and return you to the Minimum PW
window. Also, the valve will shut off automatically and exit
the Installer Menu after 20 seconds without any buttons
being pushed.
