Rugby 410/420 DG 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 informa-

tion specific to your jobsite requirements.

The Rugby Grade lasers are rugged, accurate and fully electronic with an

operating range (diameter) of up to:

• Rugby 410DG: 2600 feet (800 meters)

• Rugby 420DG: 3600 feet (1100 meters)

The Rugby 410/420 DG is a dual grade laser and is capable of producing

an accurate plane of laser light for applications that are level (1), single

grade (2) or dual grade (3).

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". For highest accuracy refer to the

Axis Alignment application.

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 410/420 DG can have up to 15% grade simultaneously in both

axes, or up to 25% in one axis.

Grades above 15% in one axis require that the cross axis grade be ±1%

or lower. In this situation, if attempting to enter grades greater than 1%

or 15%, a notice will appear on the screen when the button is pressed.

Press POWER to turn the Rugby on.

Press X/Y once to enter X-axis grade. Press X/Y again to enter

Y-axis grade.The display will show the grade entry screens.

Use the UP or DOWN buttons to set the desired grade.

Press X/Y 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/Y to exit.

Rugby 410/420 DG 7Operation

)If no button is pressed, the display will revert to the main display after

ten seconds.

Grade Swap The grade in the X and Y axes can easily be swapped from positive to

negative in the Grade Entry by Digit screen.

A typical application for this feature is road building. For example, with

the Rugby setup on the crown of the road and with one axis aligned to

the center line, the 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 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 – When positive grade is entered in the Y-axis, grade will

increase in this direction.

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.

As shown, the direction of the X-axis is seen from the front of the Rugby,

sighting over the top of the Rugby.

Rotate the Rugby slightly until the sights are aligned with your second

control point.

Once aligned, work can begin.

Slope = 0.0059

Conversion = 0.0059 x 100

Percent of Grade = 0.590%

)An optional sighting scope is also available.

)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.

3.6 Axis Alignment Application

The Axis Alignment Application is designed to precisely align the axis

when grade accuracy is extremely important. For most applications, the

traditional sighting method (using the sights on the laser, or using the

optional sighting scope) is sufficient, but when precise grades are crit-

ical, it is important to have the axes accurately aligned. This Axis Align-

ment Application is only available on the Rugby 410/420 DG.

How to use the Axis Alignment Application:

Preparation Power up the laser and enter the desired grade.

(For Example: X=+10.000% and Y=+2.000%).

To establish a proper laser position, make use of the sights on the top

of the laser (or the optional scope) and adjust the laser on the tripod so

that the axis you intend to precisely align is aimed at your second control

point. We recommend using the X-axis when possible.

Using the optional remote control, the Axis Alignment procedure can be

a one person operation. With-out the remote control, two people are

needed to complete the set-up.

Be sure the remote control is 'enabled' if you intend to use it for this set-

up. Refer to page 17 of this manual.

Step 1 Access the Axis Alignment Application (directly from the laser or via the

remote control).

From the main operation screen:

Press the STAR button once.

Press the X/Y button once.

Use the UP / DOWN buttons to toggle to the Axis Alignment

Application.

Press the STAR button once to start the application.
