Machine Control System
EG-Series

System Description
The EconoGrade Machine Control System was designed to let you achieve maximum control of your
grading system, at a very friendly price. The EG Series system is versatile, and can be installed on a
number of machines including box blades, box scrapers, graders, mini-graders and skid steers. The
system controls any valve package, giving the user both LED and a real-time LCD display so you are
always in touch with the blade position. The EconoGrade receiver can detect any rotating red beam
laser within its 173mm (7”) capture range, and in turn indicates the blade’s position to within a 2mm
(5/64”) accuracy. The receiver has LED indicator lights that give the same output as the control box
LED indicators. So whether you’re standing on the eld, or driving the machine you’ll always know
where your blade needs to be. The control box allows the user to congure the display to indicated
variances from the on grade position in real time. The receiver is able to attach to a 45mm (1 3/4”)
standard pipe. The complete system requires 9 - 30vdc to operate. The valve output drive is rated for
5 amps.

Main Control Screen
Splash Screen -The EG Series has many menu screens for
setting up the system parameters. The rst to show up after
power on is the splash screen displaying system type and
version. The version and version date may change as features
and program modications are implemented.
The Main Control Screens: This is the rst screen displayed
after the 10 second start up routine is complete. The value
on the top left of the working screen is the actual value being
received by the receiver. The value on the top right side of the
working screen is the offset entered by the user.
The “No Beam Detected”- This image displays what the work-
ing screen will look like when the receiver loses the signal hit
from the laser during operation. The user entered offset is still
shown on the top right of the screen, however the actual on-
grade value is replaced on the screen by dashes.
The “Laser Receiver Bad”- EG Series has self diagnostics to
keep your system working at peak performance, if a problem
occurs the main screen will display a message for the operator.
This is the screen you will see if there is no receiver connected
to the system, or if the control box can’t communicate with the
receiver. This may indicate a disconnected receiver or problem
with the cables
Operator menu - Entered by pressing the menu button.
System Lockout Screen - When entering the menu screens,
the system lockout screen will appear. You must enter the
system password to be able to go any further into the menu
screens. If this option is not needed it may be disabled in the
installation menu.
Filtering: The ltering rate is a mathematical averaging lter
that can help to cure any jumpy behavior of the receiver. The
best setting is one place to the right of Fast for most applica-
tions
On-Grade Dead band - Is the amount of allowable on-grade
tolerance. The range is 1mm to 30mm at 1mm steps. When the
receiver is receiving the laser light in the on-grade position, the
valves will not activate until the dead band range is passed. If
the on-grade dead band is set to 10mm, the valves will not be
activated (Hydraulic Valve On) until the receiver readings are
beyond 5mm in either direction.

Horn - Sets the function of the internal beeper (Off, Alert,
Indicate). The Alert function has not been implemented at
this time. Setting the Indicate mode will sound a detector style
indication to the receiver position to on-grade. A double beep
when too high, a single beep when too low and a solid beep
when on grade while the system is in Automatic. Most opera-
tors leave this setting to Off.
Knob Adjust - Sets the function of the rotary knob from dis-
abled (no function) to On Grade or VlvGain. When set to On
Grade the knob will adjust the on grade position on the receiver
up or down. If set to VlvGain, the knob will adjust the valve
gain hydraulic setting. This gives the operator the ability to
adjust the aggressiveness of the hydraulic system on the y.
Units - Set the system’s units to Millimeter, Inches or Feet
Latec Info Screen - The nal screen in the Operators Menu
displays Latec Info, Name and phone number. Outside of North

Valve Types - EG Series can control Proportional Time (‘bang-
bang’) valves, electric actuators up to 6 amps, proportional
valves with ratio-metric integrated electronics (Danfoss) and
proportional current (variable ow) valves, 50 Hz., 100 Hz., and
200 Hz.; Consult the valve manufacturer to nd the proper type
and dither frequency for your variable ow valve.
Proportional Time - 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.
Servo Motor - The EG Series valve outputs are recongured
to an H-Bridge style push-pull drive capable of driving electric
actuators. This drive has a maximum current limit of 6 amps.
Danfoss - setting, as well as producing the low power ana-
logue 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.
Proportional Current - The EG Series valve output is a
pulse-width-modulated signal with a settable dither frequency
of 50, 100, 200 Hz. The output voltage will, during the valve on
time, be equal to the DC input supply.
Valve Control Direction - The Valve Control Direction can be
changed to alleviate the need to change wiring or hydraulic
plumbing. To enter the Valve Direction menu, the Valve type
menu needs to be active, press the Menu and Power Button
in Unison, then press the Menu button soft key to switch be-
tween Normal and Inverted valve direction.
Minimum Pulse Width - sets the Hydraulic Valves minimum
speed.

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.

Valve setup - the setup menu ow changes depending on the
valve drive type selected. Here we will go through the 4 control
output types.
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. Refer to the
wiring diagram for the proper wire connections.
Valve Cycle Time - This menu function sets how often the
valve pulses are sent to the hydraulic valve called hits per-
second. The range is 1 to 15 hits per-second and unit is in
milliseconds, to calculate the hits per-second divide 1 by the
milliseconds. eg.1/0.250 = 4 hits per-second. The lower the
number the more hits per-second. For most hydraulic systems
starting at 100ms or 10 hits per-second is a good place to start.
The faster you can hit the valve the ner the cylinder move-
ments, the smoother the control. The valve response will differ
for valve to valve.
Valve Drive Conguration - This menu function sets how the
valve drive operates the valve coil. Set to Curr.srce the con-
trol box drive will provide a voltage to activate the valve coil,
the other side of the coil will need to be connected to ground.
Set to Curr.sink the control box drive will provide ground to
activate the valve coil, the other side of the coil will need to be
connected to + battery voltage.
Valve Drive Current Limit - A few of the valves on the market
may require a limited amount if drive current, as not to damage
the valve itself. When the valve drive is set to Curr.srce, the
next menu will allow you to enable the Current Limit and set
a current limit to a maximum of 4.8 amps. If there is a current
limit required the valve information will tell you, make sure to
check all valve specication prior to setup.
When the valve drive is set to Curr.sink the current limit will
not be available. For most of the hydraulic valves on the mar-
ket, this function will not be required.

CAUTION:
THE FOLLOWING ITEMS WILL OPERATE THE
HYDRAULIC VALVE. BE CAREFUL WITH THEIR USE!
MAKE SURE YOUR AREA IS CLEAR.
Minimum Pulse Width - EG Series needs information about
the hydraulic 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.
Valve Gain - The span of error between the onset of valve
operation and the point at which the valve is fully open is deter-
mined by the valve gain setting. In this case, the units dis-
played (percentage) are arbitrary, but higher numbers suggest
more vigorous 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.
Balancing PT Valve Servo - These three settings as well as
Valve Gain are important in Balancing the hydraulic servo.
The most important of the three is the Valve Dead-band, it must
be set to a realistic value that your machine’s geometry can
handle. The next in importance is the Minimum PW, this sets
the hydraulics systems slowest speed, if too fast the servo will
never have the ability to balance and control grade. The last
setting, Valve Cycle Time sets the over all cylinder speed. If
set too high the cylinder movements will be too large and the
servo will never be able to balance. Conversely set too low the
cylinder movements will be too small and a balanced servo will
not be achieved. A balance in these three settings while the
machine is working under it’s normal load should give you good
hydraulic control.
Note: Pressing the “Stop” soft key will turn off the valve
drive, and return you to the Minimum PW window. Also,
the valve will shut off automatically after 20 seconds with-
out any buttons being pushed.

Servo Motor - The EG Series valve outputs are recongured
to an H-Bridge style push-pull drive, capable of driving electric
actuators. This drive has a maximum current limit of 6 amps.
Refer to the wiring diagram for the proper wire connections.
Drive Cycle Time - This menu function sets how often the
output pulses are sent to the actuator called hits per- second.
The range is 1 to 15 hits per-second and unit is in milliseconds,
to calculate the hits per-second divide 1 by the milliseconds.
eg.1/0.250 = 4 hits per-second. The lower the number the
more hits per-second. For most Actuator systems starting at
100ms or 10 hits per-second is a good place to start. The fast-
er you can hit the actuator the ner the cylinder movements,
the smoother the control. The actuator response will differ
between actuator manufactures.
Push-Pull Drive - This menu function recongures the valve
drive to operate as a Push-Pull output. This will provide a
forward and reverse drive to the actuator.
Actuator Drive Current Limit - If there is a current limit
required for the actuator you can enable and set the current
limit required for your actuator. Most actuators on the market
today will not require current limit, you can disable the current
limit. Be aware that our drive has a max current capability of 6
amps.

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.

the servo will never be able to balance. Conversely set too low
the cylinder speed changes will be too small, a balance servo
will not be achieved. A balance in these three settings while
the machine is working under it’s normal load should give you
good hydraulic control. Page 16

EG Series Remote Toggle Switch Assy - You can control your
EG control box from a remote location with our optional two switch
remote. One switch toggles the EG Series between automatic
and manual mode, the other raises and lowers the control cylinder.
The switch assembly attaches to any lever using the universal
U-bolt assembly, or can be mounted any where with some fabrica-
tion.
EG Series Installation:
EG Series Installation - Control Box: To install the control box
nd an area in the cab which will allow for the control box to be
easily viewed and controlled, but also does not interfere with the
operator’s controls and line of sight. To mount the control box use
the supplied mount as a template and drill 4 holes in the appro-
priate place. Then screw the mount into position and attach the
control box to the mount. The control box can now be adjusted for
your optimum viewing pleasure.
Receiver - The receiver can be mounted with any 1 3/4” pipe or
using the optional adjustable mast as a stand alone or with the
optional shock mount bracket. It should be mounted so that the
receiver can receive a laser hit from 360˚. This means the receiver
should clear any cab, stack or any other obstacle on the machine.
Suction Cup Control Box Mount - If a suction cup mount is
required for installation, we offer a standard mount that will receive
the existing mounting ball on the control box. This mount will allow
you to stick the control box to any clean, smooth surface. The part
number for the suction cup mount is P#: 101654 (not shown).
