Valve Gain - The span of error between the onset of valve op-
eration and the point at which the valve is fully on is determined
by the valve gain setting. In this case, the units displayed (per-
centage) are arbitrary, but higher numbers suggest more vigor-
ous valve action. With the gain set to 100%, the slightest error
will fully open the appropriate valve. This setting should be left
at 50% until after the Minimum Pulse width has been set and
the hydraulics tested to see in which direction you would like to
adjust this setting. The higher the number the more aggressive
the hydraulic system. Conversely the lower the number the
less aggressive the hydraulic system will be.
Derivative Gain - To stabilize some machine control appli-
cations, it is necessary for the control box to know not only
whether the machine is at the desired slope or not, but how
fast the slope is changing and in what direction. This is known
variously as velocity or derivative (dv/dt) feedback. The control
box can vary the amount of velocity feedback added; choose
among: “High” “Medium” “Low” or “Off” This setting can be left
at medium for 99% of all installations.
Auto Return - This function is designed to return the blade to
the receivers active range after being manually driven out of
the laser light by the Valve Raise/Lower Switch, while in Auto-
matic. The return valve drive times are adjustable in increments
of 0.5 seconds with a range from 0.5 to 7.5 seconds. Once the
receiver is within laser range Auto control will instantly return.
To disable this feature set the time to Off.
Tilt Sensing Off - This option is yet to be designed, please
leave at off position and stay tuned for further updates!
Factory Settings - All of the EG 2 variables can be restored
to their default values with this window displayed. The defaults
are restored by pushing the Restore button.
Laser Receiver - With optional cables, it is possible to add
other manufactures receiver to our system. At this point only
two manufactures are compatible: Apache and Topcon.
System Lockout Screen - This is the screen where you can
enter a new password into the box. The factory default pass-
word in every system is “1000”. If user would like this option to
be disabled set password to “0000”, the lockout will be disabled
and all menu options will be available to the user.
