event of a failure on any part of the Renishaw
system, the laser system remains safe.
In the case of laser systems with powers or
speeds capable of causing injury, it is essential
that appropriate safety protection measures
are included in the machine usage. Further
guidance can be found in the European
BS EN ISO 12100 : 2010 Safety of machinery –
General principles for design – Risk assessment
and risk reduction.
Information to the equipment
supplier/installer
It is the equipment supplier’s responsibility
to ensure that the user is made aware of any
hazards involved in any operations involving
the SLM 250, including those mentioned in
Renishaw product literature.
Warranty
Renishaw plc warrants its equipment provided
that it is operated exactly as defined in
associated Renishaw documentation.
Laser safety
DO NOT STARE DIRECTLY
INTO THE BEAM
In accordance with BS EN 60825-1: 2007 and
US standards 21CFR 1040.10 and 1040.11,
except for deviations pursuant to Laser Notice
no. 50, dated June 24, 2007, the SLM 250 is
classified as a Class 1 invisible laser product.

Introduction
3 Introduction
The SLM 250 is a ruggedised field instrument designed to produce fast, efficient 2D laser scans of
the surrounding vicinity.
It is designed to be used as a multi-purpose scanning distance meter that is integrated into other
equipment for a variety of applications.
The module employs the “time of flight” measurement technique to calculate the distance to the
target. Up to 36,000 such measurements can be made every second up to a range of 250 metres
(standard Renishaw test conditions).
The SLM 250 is just one of many laser systems that have been designed by Renishaw. Other
products – such as the Quarryman, Boretrak, C-ALS (Cavity Auto-scanning Laser System), Void
Scanner and Dynascan – have all been proved over many years of demanding use around the
world. These products complement the SLM portfolio and provide a wide range of advanced
measurement solutions to industries including mapping, mining and quarrying, traffic, offshore and
manufacturing.

Introduction
3.1 Applications
This unique instrument is suitable for a large number of surveying and measuring functions, such
as:
• security
• quarrying and mining
• coastal mapping
• topographical surveys
• highway infrastructure surveys
• vehicle/vessel positioning.

4 Equipment description
The SLM 250 incorporates an embedded infrared laser module, a motor to spin the laser, encoders
to measure the rotation angle, the connector to provide power and data communications with the
unit, and the electronic circuitry that allows measurements to be taken at ranges up to 250 metres
from the instrument.
The two windows on the laser module protect the transmitting and receiving optics. It is through
these windows that the infrared measuring laser is fired and then received back into the instrument.
It can fire at up to 36,000 times per second.
The laser can range up to 250 metres. The actual range in any given project will depend on a
number of factors, such as atmospheric and environmental conditions, and the reflectivity of the
surface being targeted.
The laser is housed in an aluminium casing. This ensures that the SLM 250 is highly ruggedised
and may be used in demanding environments.
The flange at the bottom of the SLM 250 allows it to be mounted onto a stable surface (see section
15, “Appendix A – Mechanical drawings”). Its construction means it can be mounted vertically or
horizontally, with no loss of performance.

4.1 Precautions
• Avoid directing the laser apertures towards the sun or other high-powered, infrared light
sources.
• Avoid mechanical shock.
The laser is driven by a motor. When the unit is stationary the laser can be rotated by hand without
causing damage to the motor. If the laser is prevented from rotating by an obstruction, the motor
power will initially be increased to try to maintain the rotation speed but will then detect a stall
condition and the drive will be removed, preventing damage to the motor.
Caution: If the obstruction is removed before a stall is detected the rotation speed may
momentarily be in excess of what it should be.
It is advised to minimise any manual movement of the laser and to keep the instrument away from
potential obstructions so the motor may turn freely.
WARNING: Users should not manually or otherwise obstruct the operation of the
motor or allow clothing to come into contact with the device, to avoid entrapment
in the unit.

Equipment
description
The umbilical cable is 2 m in length and provides connection for power and Ethernet. Connection
to the SLM is by means of a Mil-Spec MIL-DTL-26482 Series 1 Plug (Renishaw recommends the
use of Weald LMH06T10.07SN.101). For further details of this cable see section 16, “Appendix B –
Electrical connections”.
4.2.2 Low-voltage power connectors
The 4 mm connector plugs are for connection to a low-voltage dc power supply of voltage range
11 Vdc to 16 Vdc.
For cable pin-outs, see section 16, “Appendix B – Electrical connections”.
4.2.3 Ethernet
The Ethernet connector (standard RJ45) allows for connection to a PC/laptop so that
communication to the SLM 250 can be established.
4.3 Electrical
WARNINGS:
• The SLM 250 has no user-serviceable parts. In the event of a problem, please
contact Renishaw’s Service and Support Centre.
• Do not attempt to open the instrument.
• Always isolate the low-voltage dc source before the instrument is removed
(uninstalled) and/or replaced (installed).
• Appropriate visual inspection and electrical safety testing is to be performed
after instrument installation or replacement.
It is recommended that the SLM 250 is powered from an external 14 Vdc source with a minimum
power capability of 100 W.
Note: The SLM motor start-up peak current will be higher than its steady running current,
especially when at the low end of its operating temperature range.
