Figure 9 - Use the Integrated Laser Alignment System for Positioning
The450L PAC is a Perimeter Access Control safety light curtain that is designed for
whole body detection to create a safety perimeter around a machine or hazardous
location. To verify correct operation, first place the machine or hazardous location
in a safe state. Then interrupt the beams, refer to Figure 11 for the beam positions
of different models. Confirm that the OSSD safety output switches to the OFF state
(refer to Table 2 on page 3 for the indicator status) and remains OFF for as long as
the beams are interrupted.

ATTENTION: A 450L GuardShield™ safety light curtain system
is intended to be part of the safety-related control system of a
machine. Before installation, perform a thorough risk
assessment to determine whether the specifications of this
device are suitable for all foreseeable operational and
environmental characteristics of the application.
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, and humidity.
Without additional measures (IEC 62998), 450L-PAC
GuardShield safety light curtains are not designed to be used
in the following applications:
•Outdoors
• Under water
• Explosive atmospheres
• Altitudes over 3000 m (1.86 miles) above sea level
• With enhanced ionizing or radar radiation
ATTENTION: The protective system must be tested for proper
operation after each change to the configuration. The 450L
GuardShield safety light curtain cannot be used with machines
that cannot be stopped electrically in an emergency. Always
maintain the required safety distance (see publication 450L-
UM001 in Additional Resource on page 4) between the 450L
GuardShield safety light curtain and a dangerous machine
movement. Additional mechanical protective devices have to
be installed if hazardous machine elements can be reached
without passing through the protective field. Improper
installation can result in serious injury or death. Never connect
the safety outputs (OSSDs) to +24V DC. The Auxiliary output is
only a status output for diagnosis purposes, for example, to
connect 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 safety light curtain. Removal of either
of the gray safety light curtain end caps or the transparent
front window voids the warranty terms of this product. Do not
insert or remove plug-ins when power is applied to the plug-in.
Make sure that the power supply is protected against overload
(fuse with 3 A in the 24V DC circuit). Installation must be in
accordance with the publication 450L-UM001 in Additional
Resource on page 4 and implemented by qualified personnel
exclusively.
Damage occurs to the light curtain when screws are
overtightened. To avoid pollution or contamination, the
installation of a plug-in into a stick must be implemented in a
dry and clean area. Make sure that the rubber seal at the plug-
in does not get out of place when the plug-in is inserted in the
light curtain.
