A 450L GuardShield™ safety light curtain system is intended to be part of the
safety-related control system of a machine. Before installation, a thorough risk
assessment must be performed to determine whether the specifications of this
device are suitable for all foreseeable operational and environmental
characteristics of the application.
Installation must be in accordance with the publication 450L-UM001 and
implemented by qualified personnel exclusively.

Figure 4 - Insert Plug-in
If a 450L-E safety light curtain is used and operated with a cascading plug-in,
remove the gray slot cover insert and mount the cascading plug-in similar to the
connection plug-in.

WARNING: The following applications and/or environmental
conditions can lead to misuse and potentially cause severe
injuries or death (for more information see IEC 62046):
• Machines that eject materials, swarf, or component parts
• Risk of injury from thermal or other radiation
• Unacceptable noise levels
• Transparent objects are detected
• An environment that exceeds the specification, limits provided
in publication 450L-UM001.
Some but not all possible limits are electrostatic discharge,
radio frequency interference, vibration/shock, ambient light,
pollution, temperature, humidity.
The 450L GuardShield safety light curtain cannot be used with
machines that cannot be stopped electrically in an emergency.
ATTENTION: Without additional measures (IEC 62998),
GuardShield 450L-B safety light curtains are not designed to
be used for the following applications:
• Outdoors
• Under water
•Explosiveatmospheres
• Altitudes over 3000 m (1.86 miles) above sea level
• With enhanced ionizing or radar radiation
The protective system must be tested for proper operation
after each change to the configuration.
ATTENTION: This package content is intended for
replacement cases. For new product installation, see
publication 450L-UM001.

GuardShield Safety Light Curtain Installation Instructions
Figure 7 - Positioning of Transmitter and Receiver Sticks
Confirm that both connection plug-ins are at the same end of the installation.
Figure 8 - Install, Connect, Power-up, and Align Complete System
The 450L-E safety light curtain sticks have an integrated laser alignment system.
Place a finger on the optical switch (the square next to the hand symbol on the
front window) to switch the alignment system on and off.
Figure 9 - Use the Integrated Laser Alignment System for Positioning
For 450L-B safety light curtain sticks, an optional laser alignment tool
(catalog number 440L-ALAT) and clamp (catalog number 450L-ALAT-C) are
available.
Figure 10 - Test Resolution with Test Rod
Verify that while the test rod is anywhere within the protective field, the OSSD
safety outputs remain in the off-state. Move the test rod as indicated in Figure 10
with a maximum speed of 0.3 m/s (11.8 in/s). Be sure that the intensity indicator
indicates a continuous protective field interruption (minimum one intensity
indicator is off).
ATTENTION: Damage occurs to the safety light curtain when
screws are overtightened. To avoid pollution or contamination,
the implement the installation of a plug-in into a stick in a dry
and clean area. Verify that the rubber seal at the plug-in does
not shift out of place when the plug-in is inserted in the safety
light curtain.
ATTENTION: Do not stare into the beam. Laser Class 2.
Conforms to 21 CFR 1040.10.

Laser Optical Switch
ATTENTION: Always maintain the required safety distance
(see publication 450L-UM001) between the 450L GuardShield
safety light curtain and a dangerous machine movement.
Additional mechanical protective devices must be installed if
hazardous machine elements can be reached without passing
through the protective field. Improper installation can result in
serous injury or death. Never connect the safety outputs
(OSSDs) to +24V DC.
The Auxiliary output is only a status output for diagnosis
purposes to connect, for example, an indicator lamp. Do not
connect this output to fulfill safety functions. If the safety
outputs are connected to +24V DC, they are in the on-state and
cannot stop hazardous machine/application movements.
Do not open or attempt to repair or modify the
450L GuardShield safety light curtain. Removal of either of the
gray GuardShield end caps or the transparent front window
voids the warranty terms of this product.
Verify that the power supply is protected against overload
(fuse with 3 A in the 24V DC circuit).
