Valve Settings
Valve1 Types (Left Side) - EG Series can control proportional
time (‘bang-bang’) valves, proportional valves with integrated
electronics (Danfoss), Selective Control Valve (SCV) and propor-
tional current (variable ow) valves. There are three Proportional
current settings: 50 Hz., 100 Hz., and 200 Hz.; Consult the valve
manufacturer to nd the proper type and dither frequency for your
valve.
In Proportional Time mode, the EG Series valve output is an on/
off voltage, high current output; the output voltage will, during the
valve on time, be equal to the DC input supply.
In Proportional Current mode, the EG Series valve output is a
pulse-width-modulated, high current output; the output voltage
will, during the valve on time, be equal to the DC input supply.
The Danfoss setting, as well as producing the low power an-
alogue control signal for the valve, also drives both of the high
current valve outputs. One of those high current outputs can
supply power to the Danfoss valve, and the other can operate the
hydraulic system loading valve as recommended by the manu-
facturer.
Valve Control Direction can be changed to alleviate the need
to change wiring or hydraulic plumbing. To enter Valve Direc-
tion menu, press the Menu and Power Button in Unison, then
pressing the Menu button will switch between Normal and Invert-
ed

CAUTION: THE FOLLOWING ITEMS WILL OPERATE THE
HYDRAULIC VALVE. BE CAREFUL WITH THEIR USE! MAKE
SURE YOUR AREA IS CLEAR.
If your valve has been set to either proportional current or Danfoss go to Mini-
mum DC setting on next page. Proportional time continue with below.
Minimum Pulse Width - The EG Series needs information
about the hydraulic system on your machine, as all hydraulic sys-
tems are not the same. Here we are telling the system the signal
needed to move the cylinder at its slowest speed. Pressing the
Menu (Test) button will enter you in to this routine. Your hydrau-
lics will begin to move, use the right toggle switch to increase or
decrease the signal to the valve until you get a blade movement
of approximately 0.5 inches per second. Press the menu button
to change the direction, then adjust the cylinder speed for the
opposite direction. When the cylinder speed is OK then press the
power button (Stop) 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.
