Rugby 320 SG Introduction4
1 Introduction
The Rugby Grade laser is designed to serve your needs in a wide variety
of applications.
It is a proven tool for increased production with substantial reduction of
labor, time and material costs. It can be used to accurately control land
leveling, sloped or level grading, trenching, open cut mining, dredging,
contouring of levees, general construction and excavation.
This manual contains operating and set-up procedures for common
applications. Its purpose is to describe the features of the Rugby and
how the Rugby operates. The manual is not intended to describe specific
applications. Contact your local dealer or Leica Geosystems for information specific to your jobsite requirements.
The Rugby Grade lasers are rugged, accurate and fully electronic with an
operating range up to 3000 feet (900 meters) diameter.
The Rugby 320 SG is a single grade laser and is capable of producing an
accurate plane of laser light for applications that are level (1) or having
a single grade (2).
Alignment is as easy as sighting over the top of the Rugby to your control
point using the integrated alignment sights or the optional sighting
scope assembly. For increased accuracy, follow the procedure for "3.5
Precise Alignment of the Axes".

3.1 Entering Grade
Direct Grade Entry
Grade Entry by
Digit
Grade Zero The grade in either axis can quickly be set to zero by pressing both the
Up and Down buttons simultaneously while in either grade entry mode.
When changing grade using the direct entry method, the counter will
always stop at zero. Release the button and press again to continue
counting beyond zero.
Grade Capability The Rugby 320 SG can have up to 25.000% grade in the X-axis.
The Y-axis does not have grade capabilitiy, and is a “level only” axis.
)
If no button is pressed, the display will revert to the main display after
ten seconds.
Press POWER to turn the Rugby on.
Press X to enter X-axis grade mode.
Use the UP or DOWN buttons to set the desired grade.
Press X to exit.
While in the grade entry screens, press the STAR button and a
cursor will appear on the +/- sign.
Press the STAR button to move the cursor to the right.
Press the UP or DOWN buttons to change the sign or the digit
that is highlighted.
Press X to exit.

Grade Swap The grade in the X-axis can easily be swapped from positive to negative
in the Grade Entry by Digit screen.
Align the Y-axis (level) to the center line, the X-axis or cross axis grade
can be made to fall to the right or lefthand side simply by changing the
+/- sign on the display.
Grade Matching In Direct Grade Entry mode the movement of the leveling mechanism
moves at the same speed as the grade counters.
To match an existing slope, set up the laser over the known gradebreak
(base) of the slope, and align the cross axis (level only) of the laser to
the end of the slope with both control points parallel to the direction of
grade.
Adjust the Rod-Eye receiver on your grade rod for the elevation of the
laser at the gradebreak next to the laser.
Move the grade rod to a point on the slope that is too be matched. Then,
dial grade into the laser until the Rod-Eye indicates an on-grade reading.
The percent of grade in the display is now equal to the grade being
matched.

3.2 Identification of the Axes
1. X+ Axis – When positive grade is entered in the X-axis, grade will
increase in this direction.
2. Y Axis – Always level
3. Front of Rugby – See also axis labeling on the side of the laser and
inside the top windows.
3.3 Slope - Percent of Grade
Slope The change in elevation per unit of measure (foot, meter, etc.)
Percent of Grade The change in elevation per 100 units of measure (feet, meters, etc.)
Calculating Percent
of Grade from the
Slope
3.4 Alignment of the Axes
When the desired grade is correctly set in the display, it is necessary to
align the X and Y axes to the jobsite.
Ensure the circular level vial is positioned near the center of the circle for
maximum self-leveling capability.
Ensure the Rugby is properly positioned over a control point.

Rotate the Rugby slightly until the sights are aligned with your second
control point.
Once aligned, work can begin.

For very accurate alignment, refer to the steps for Precise Alignment of
the Axes.
3.5 Precise Alignment of the Axes
Under most conditions, the raised alignment marks on the top of the
Rugby are adequate for alignment of the axes. However, for more
precise alignment, use the following procedure.
Objective • To establish Point A on the Y-axis as a reference and take an eleva-
tion reading.
• To dial grade into the X-axis and then adjust the position of the laser
until the original elevation at Point A is again found.
Procedure 1. With 0.000% grade in both axes, set up the Rugby directly over a
grade stake and rough align the Y-axis to a second grade stake that
we will call Point A.
2. Take an elevation reading at Point A using a Rod-Eye Receiver and a
survey rod.
3. Enter +5.000% grade into the X-axis. When grade is entered in the
X-axis, the Y-axis acts like a hinge or fulcrum.
4. With 5.000% in the X-axis, take a second reading at Point A.
Alignment • If the second reading is equal to the first reading, the X-axis is
aligned correctly.
• If the second reading is greater than the first reading, rotate the
Rugby clockwise (to the right) until the two readings are the same.
• If the second reading is less than the first reading, rotate the Rugby
counter-clockwise (to the left) until the two readings are the same.
Rugby 320 SG Setup10
4 Setup
4.1 General Setup
Location Make sure the location is clear of possible obstructions that may block
or reflect the laser beam.
Make the most efficient use of the Rugby’s operating radius. The Rugby
can be placed in the center of the working area or to one side.
Make sure the ground is stable. Ground vibration and extremely windy
conditions can affect the operation of the Rugby.
If working in very dusty conditions, place the Rugby up-wind. The dirt and
will then be blown away from the Rugby and reduce interference.
Recommended
Head Speeds
For surveying and manual machine control applications the typical head
speed is 10 rps (600 rpm).
For automatic machine control applications it is recommended to use the
highest head speed, 20 rps, to increase the frequency of updates.
When working at extended distances, decreasing the head speed
(increasing the pulse time on the receiver) or changing the band width
of the receiver to wide band can improve distance and performance.
Tripod Setup Attach the Rugby securely to a tripod or laser trailer, or mount on a
stable level surface.
Always check the tripod or trailer before beginning work.
Make sure all screws, bolts, and nuts are tight.
If your tripod has chains, they should be slightly loose to allow for
thermal expansion during the day.
On extremely windy days, secure the tripod. Placing a sandbag on each
leg can do this. (See also adjustment for setting the wind sensitivity of
the Rugby.)
If using a tripod with a quick disconnect adapter, point the control lever
into the wind. This places the locking mechanism also into the wind, and
will provide better stability.
4.2 Setup Options
The Rugby has several setup options that are easily accessed and
changed in the first setup screen.
From the main operating screen, Press STAR to access the
setup screen.
