1 Safety
b
Read the entire Quickstart before using the device.
b
Connection, assembly, and settings must be performed by
competent technicians.
b
Do not connect external I/O signals to the device while it is
powered. This may damage the device.
b
Do not use the device in areas with risk for explosion.
b
Safe operation has a dependency on the selected laser
class of the device (see
E
). Carefully study the Laser safety
section
A
and the safety instructions in Ruler E Reference
Manual.
2 Product Specification
Ruler E is a high-speed 3D camera that can measure up to
10,000 shape profiles/s. The device is factory calibrated
and measurements are provided in a metric scale (mm). The
camera can also provide gray scale and laser scatter informa-
tion at the same time.
Ruler E has an in-built light source (laser). It is designed for
rough industrial environments, and is protected by a robust
IP65 housing. It is available in several variants (see
E
) with
options for different fields-of-view, laser power, window material,
heating elements for cold environments, and laser scatter
measurements.
Ruler E serves as a data streamer, from which the measure-
ment data is transferred through a Gigabit Ethernet connec-
tion to a PC for further processing. The Ruler can be started,
stopped and configured by applications running on the PC.
Note that the 3D Camera Development software is required
to build such applications. Ruler E is intended to be the vision
component in a machine vision system.
The ISM Radio Frequency Classification is Group 1, Class A
(EN55011).
a
Warning:
Class A equipment is intended to be used in
an industrial environment.
3 Connections
C
Ruler E is connected to a 24 V DC power supply, and to a
PC running Windows 7/XP equipped with a Gigabit Ethernet
network board.
b
The power supply is connected to the Power I/O connector
(M12 connector).
b
The Gigabit Ethernet board in the PC is connected to the
Gigabit Ethernet connector, either directly or through an
Ethernet switch.
b
I/O signals that are used, for example pulse trigger signals
from encoders or an enable signal from a photoelectric
switch, are connected to the Power I/O and the Encoder
connector respectively (M12 connectors).
4 System Requirements
b
PC
Recommended: Windows XP Pro 32/64 bit or
Windows 7 32/64 bit, at least 4 GB memory,
Gigabit Ethernet network card supporting jumbo
frames.
b
Ethernet
cable
Up to 70 m using CAT 6 cables.
For longer distances or tough environments,
opto cables can be used.
5 Installation
B
a
Ensure that all laser safety requirements for the
appropriate laser class system are fulfilled (see
A
and
Ruler E Reference Manual).
a
Ensure that the Ruler is unpowered during the installa-
tion process.
b
Install the Gigabit Ethernet board
a
and the 3D Camera
Development software
b
on the PC.
b
Mount the Ruler in respect to the defined field-of-view
F
,
and other equipment to be used by the vision system such
as encoder and photoelectric switch.
b
If I/O signals are used, such equipment may be connected
to the Power I/O via a T-junction
c
or a terminal box
d
.
Encoder is connected directly to the Ruler.
b
Connect the Gigabit Ethernet connector on the Ruler to a
dedicated Gigabit network, or directly to the Gigabit network
connector on the PC using a Gigabit Ethernet cable
e
.
b
Connect an unpowered 24 V DC power supply
f
to the Power
I/O connector on the Ruler.
b
Switch on the power supply.
For detailed installation instructions, see the Ruler E Refer-
ence Manual that can be found on the 3D Camera Develop-
ment software CD, or downloaded from:
visionsupport.sick.com
6 Service and Maintenance
The Ruler E contain no user serviceable parts inside. The
warranty of the device will be void if opened.
a
Warning:
To avoid hazardous radiation exposure, the
power to the laser unit of the Ruler must be turned off
before maintenence is performed
b
Check screw connections and connectors at regular
intervals.
b
Clean the housing with a soft cloth, dry or dampened with a
mild water diluted cleaning agent without powder additives.
In case of unit failure, please contact SICK or a SICK represen-
tative that delivered the unit for further instructions.

Laser Safety
The legal regulations on laser safety for the laser class
of Ruler E must be adhered to.
Ruler E class 3B
is equipped with a Class 3B laser according to EN/
IEC 60825-1:2014 and EN/IEC 60825-1:2007. It
complies with 21 CFR 1040.10 except for deviations
pursuant to Laser Notice No. 50, dated June 24, 2007.
It cannot be considered as a stand-alone unit and must
only be used as part of a laser system which incorpo
-
rates additional features depending on class 3B.
a
Danger: Ruler E 3B has to be considered danger
-
ous to retinas if exposed. The classification to
class 3B leads to the necessity of additional
safety requirements which have to be fulfilled.
b
The user has to name a laser safety officer (follow
national standards).
b
A key-box with a removable key
d
. Without the key it
should not be possible to power-on the laser unit.
b
A connector readily available for connecting a remote
emergency stop and/or remote barrier interlock.
b
A beam attenuator and an emission indicator must be
available in the system.
b
The device must be integrated into a setup with
adequate optical encapsulation according to laser
safety regulations (safety interlock and casing).
Ruler E class 2 (2M)
is equipped with a Class 2 laser according to EN/IEC
60825-1:2014 (2M according to EN/IEC 60825-1:2007).
It complies with 21 CFR 1040.10 except for deviations
pursuant to Laser Notice No. 50, dated June 24, 2007.
a
CAUTION: Class 2 (2M) lasers emit visible radia
-
tion in the wavelength range from 400 nm to 700
nm where eye protection is normally afforded by
aversion responses including the blink reflex.
However, viewing of the output is hazardous if the
user employs optical instruments within the beam or
suppresses aversion responses intentionally. Temporary
irritating optical influence (glare, flash blindness,
after-image) on the human eye can not be excluded, in
particular in combination with low ambient light level.
b
Do not stare into beam.
b
Do not view the laser beam directly with optical
instruments like magnifying glasses.
b
Do not aim the laser beam of the device at the eyes of
a person.
For both laser classes
b
Reconsider newest laser safety regulations.
b
Do not open the housing of the device.
a
Danger: The laser may be activated as soon as
the Ruler E is powered on. Avoid direct exposure
to the laser beam. Avoid looking at the laser
reflection.
Ruler E is a laser product, and operation using procedures
other than those specified herein may result in hazardous
radiation exposure.
b
During installation and alignment operations appropriate
eye protection should be used.
b
To sustain these specific laser classes no maintenance is
necessary.
