Introduction
Thank you very much for purchasing this product from Topcon. In
order for it to serve you long and well, we ask that you read and
carefully follow the instructions contained in this manual. If you
have any questions, please contact your local authorized Topcon
dealer for assistance.
Topcon’s LS-B2 is a machine mounted laser sensor. Used in
conjunction with a rotating laser elevation reference, the LS-B2
helps operators get to grade quickly and accurately.
In manual control, the LS-B2 senses the position of a rotating laser
reference and flashes a clearly visible raise, lower, or on-grade
signal to the operator. The operator then corrects the position of the
cutting edge according to the signal. In automatic control, the LS-
B2 sends the signals directly to the machine’s hydraulics which
make the correction automatically.
The LS-B2 transfers easily from machine to machine and offers the
choice of on-board batteries or machine battery powered operation.
The LS-B2 has a unique infrared communication option called the
IR-2. The IR-2 receives an infrared signal from the LS-B2 and
transfers that signal to the RD-2 remote display mounted in the cab.
Used with the on-board battery pack, the infrared option removes
the need for cables between the LS-B2 and RD-2. This is an
advantage where routing cables from the sensor to the cab or from
the sensor to the battery is difficult and prone to accident.

Installation
Mounting the System
Before installing your LS-B2 system, turn to page 7 to confirm that
you have received all system components. If you have not, contact
your local Topcon Laser Systems dealer for help.
The LS-B2 has been fitted with a clamp that attaches the unit to any
round pipe or pole 1.74" to 2.0" (44.45mm to 50.8mm) in diameter
or square pipes with sides from 1.5" to 1.95" (38.1mm to 50mm).
To Mount on a Machine Stick
To mount the LS-B2 on a backhoe or excavator, you must first have
a pipe attached to the machine stick. Weld two brackets to your
stick. Bolt or otherwise attach your mounting pipe to the brackets.
Then, clamp the LS-B2 onto the pipe.
To Mount LS-B2:
A: Close Bracket Over Pipe.
B:
Close Other Half of Bracket so
Threaded Shaft w/Centering Ball Sits
Firmly in Slot.
C: Turn Handle Until Tight.

To Mount on a Blade or Screed
With pavers, motor graders, dozers, and scrapers, the LS-B2
attaches to a pole or mast that is mounted on the screed or blade.
Clamp the LS-B2 to the pole just as you clamp it to a pipe.
To Mount the RD-2 Remote Display
Using the head bolts and nuts supplied, mount the RD-2 to either a
vertical or horizontal surface in the cab.

Operation
Your LS-B2 can be used alone or with a remote display.
LS-B2 Only
Using the LS-B2 only, manually control grade by raising or
lowering your cutting edge according to the LS-B2’s LED display
signals.
Basic automatic control is available using only the LS-B2, although
we recommend automatic control capability with the LS-B2/RD-2
combination.
LS-B2 and RD-2
The LS-B2 provides either automatic or manual control when used
with the RD-2 remote display. The RD-2 improves LS-B2 ease-of-
operation.
Mount the RD-2 in the machine’s cab so that the grade display
signals are within easy view. Grade signals become much easier to
see when used with the RD-2 remote display.
When the RD-2 is connected to your machine’s valves, a switch on
the front panel allows operators to select either manual or automatic
control, depending on the application. Also, the RD-2 features
switches to manually raise or lower the machine cutting edge.
These switches override automatic control.
IR-2
The LS-B2/RD-2/IR-2 combination provides an infrared
communication option for convenient wireless operation in manual
control applications. The IR-2 is an infrared receiver that connects
to the RD-2 and enables the LS-B2 grade display signals to be
transferred to the RD-2 cab-mounted display without a cable.

Operation
LS-B2 Operator’s Manual

To Use the Infrared Option:
1Position the IR-2 receiver so that it faces and is within
clear line of sight of the LS-B2.
2Connect the IR-2 to the RD-2 with the attached cord.
Normally the IR-2 mounts on top of the RD-2.
However, by using an optional IR-2 extension cord,
you can mount the IR-2 in a location of your choice.
See your Topcon dealer for information.
3Position the LS-B2 on the pole or pipe so that the
grade display window faces the IR-2.
When using the LS-B2 infrared option, power comes from the BT-
39Q battery pack, so no cords are necessary between the LS-B2 and
the RD-2 or between the LS-B2 and the machine’s battery.
LS-B2 and Automatic Control Systems
The LS-B2 can be used as part of most Topcon automatic control
systems. By connecting the LS-B2 to a Topcon control box and
integrating it into the system, the LS-B2 helps provide high
precision grade control to excavators, graders, pavers, dozers,
milling machines, and Ag land leveling machines. See your
machine control manual for operating and installation details.
Consult your dealer to equip your LS-B2 for automatic control
using its valve drivers and RD-2 control panel.

8Affix the LS-B2 firmly to its mounting pipe or pole.
The RD-2 will flash all four display panel lights if it is not
receiving communication from the LS-B2. If this occurs
while you are using the infrared option, an adjustment to
the position of the IR-2 may be necessary.
To Use the RD-2 Automatic Controls
If you or your dealer has connected the RD-2 to your machine’s
hydraulic valves, you can switch from manual to automatic control
and the reverse by pressing the RD-2 AUTO button.

Grade Display Signals
Both the LS-B2 and RD-2 have grade displays which show the
direction of adjustment needed to reach grade. The display consists
of grade arrows if a correction is required and a horizontal bar
signal when on-grade.
