System Description
Automatic Blade Control is used on construction grading machinery to
automatically control the blade in earthmoving and grading applications.
It is also used on agricultural drainage and land leveling machinery.
A laser receiver mounts above the cutting edge of the blade. A control
box and a hydraulic installation kit tie into the machine's hydraulic
system. Grade information from a rotating laser is processed and
automatically directs the machine's hydraulics to maintain the elevation
of the blade.
Control Box:
The control box mounts in the cab. The operator can easily select
automatic or manual control. An LED display indicates the position of
the blade.
Adjustments can be made for deadband or accuracy from 0 to 1.50
inches (38 mm) in 1/10 inch (2.5 mm) increments. When used with
the MCR1+, the deadband range is 0 to 1.0 inch (25 mm). Adjustment
of the hydraulic speed (gain) is also possible in the cab. Additional
adjustments provide optimum blade control performance for various
types of machinery and conditions.
The control box is designed to work with proportional time (PT)
on/off hydraulic solenoid valves, commonly referred to as "bang-bang"
valves.
Receivers:
All receivers feature 360 degree laser reception and work with all
common rotating lasers. Proprietary and patented advanced proportional
photocell technology assures maximum accuracy.

The 3 left side switches (10, 11, 12) are used by the operator to set
operating functions. Detailed information starts on page 6.
The 3 right side switches (13, 14, 15) are used during installation for
specific valves and machine settings. These should not be changed
by the operator.
Contact the installation technician for additional

Configuration
The system operation is a function of deadband setting, gain selection,
laser RPM, machine speed, hydraulic pressure and flow, installation
settings, and general site or field conditions. The user selectable factors
of the control box are the deadband, the gain and the LED displays.
Two rotary switches are provided for selecting the on-grade deadband
(10) and the gain (12), while a dip switch (11)
provides for LED display
selections. These switches are located
behind the access panel on the
bottom front of the control box. Turn the 2 thumbscrews counterclockwise
and remove the panel from the box housing to access the switches.
On-Grade Deadband (Accuracy) Selection Switch (10):
The on-grade deadband rotary switch (10) provides 16
positions of deadband selection with "0" being the smallest
and increasing clockwise to "F" which is the largest. The table
below lists the corresponding on-grade deadband for each
switch position. Each number or letter setting represents an
increment of one-tenth inch (0.10 inch) or approximately 2.5 mm.
0 1 2 3 4 5 6 7
in. 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7
mm 0 2.5 5.1 7.6 10.2 12.7 15.2 17.8
8 9 A B C D E F
in. 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5
mm 20.3 22.9 25.4 27.9 30.5 33.0 35.6 38.1
NOTE: The MCR1+ uses 10 positions from "0" to "A" for a deadband
range of 0 to 1.0 inch (2.54 mm). Positions "B" to "F" remain at the 1.0
inch deadband. Other MCR receivers use all the positions.
Examples:
The deadband setting of "5" would correspond to ½ in. (12.7 mm).
The deadband setting of "A" would correspond to 1.0 in. (25.4 mm).
The default on-grade deadband is set to "8" or 0.8 in. (20.3 mm).

Configuration
Dip Switch (11) Settings:
The dip switch panel consists of 4 individual switches.
The up position is ON and the down position is OFF.
The function of each switch and their factory default
settings are as follows:
Switch # Function Position Default Position
1 Laser strike averaging off OFF OFF
Laser strike averaging on ON
2 Receiver LED's disabled OFF OFF
Receiver LED's disabled ON
3 Control Box LED's bright OFF OFF
Control Box LED's dim ON
4 Linear Gain OFF OFF
Exponential Gain ON
1. Laser strike averaging - This switch is normally in the OFF position.
It is turned ON only when required for long range applications where
the rotating laser may be relatively unstable due to environmental or
jobsite conditions.
2. Receiver LED disable - The receiver LED's will be displayed when
the switch is in the default OFF position. There will be no display on
the receiver LED's when the switch is in the ON position.
3. Control Box LED's - The default OFF position and normal operating
setting for the control box are LED's "bright". The control box LED's can
be set to dim by changing this switch to the ON position. This may be
preferred at night or in low light conditions.
4. Linear or exponential gain is usually set depending on the charac-
teristics of the spool in the hydraulic valve. Do not change this setting
without consulting the installation technician.
Configuration
Gain Selection Switch (12):
The gain selection rotary switch (12) provides sixteen
positions with "0" being the slowest reacting and increasing
clockwise to "F" which is the fastest reacting.
When the receiver is in the on-grade deadband, no
correction signals are sent to the valve. Immediately after the receiver
moves outside of the on-grade deadband, signals are sent to correct
the elevation. As the receiver moves further away from the on-grade
deadband, the valve continues to open until the valve is in the 100%
open state. The distance between this initial opening of the valve and
the 100% open state is controlled by the gain.
The default gain setting is "8". Field adjustments may be necessary
due to the many other variables in the system operation and jobsite
requirements. If the system becomes unstable, overreacting between
above
grade and below grade, increase the deadband setting
or
decrease the gain setting.
