This quick start provides a summary of the basic steps that are required to
configure and run a system using 450L light curtains in minimal time.
Product Overview
The 450L GuardShield™ safety light curtain family is designed for use on hazardous
machinery for Point of Operation Control (POC). The product family is certified as
Type 4 electro-sensitive protective equipment (ESPE) (as defined by EN 61496-1
and IEC 61496-2) and can be used in applications that require up to and including
PLe category 4 according to EN ISO 13849-1.
The 450L safety light curtain family consists of two product lines:
• 450L-B (Basic): Suitable for basic ON/OFF applications.
• 450L-E (Enhanced): Provides enhanced features for more sophisticated
applications.
Plug-ins are available to provide for additional functions, like muting. See
publication 450L-UM001 for full specifications, details on both products, and
available accessories.
Requirements
See firmware revision information in publication 450L-UM001 for information and
the PCDC to download firmware. If you use Connected Components Workbench™
software, version 12 or later is required.
Workflow
1. Verify that you have all required parts
2. Configure the light curtain
3. Assemble, position, and mount the light curtain
4. Wire, apply power, and align system
5. Verify correct operation
Step 1: Verify that you have all required parts
A 450L GuardShield safety light curtain is normally shipped as an individual

450L GuardShield Safety Light Curtain Quick Start
The transmitter and cascading plug-ins do not have DIP switches, this functionality
is only on receiver and universal plug-ins.
If you are configuring the light curtain with Connected Components Workbench
software, set DIP switch 1 to ON. Otherwise, use the settings that are defined in the
following tables.
Figure 2 - DIP Switches
After you check the DIP switch settings and configure as required, insert the
plug-ins into the sticks.
For more information on these functions, proper configuration, configuration via
software, and configuration confirmation see System Configuration in publication
450L-UM001.
Step 3: Assemble, position, and mount the light curtain
After setting the plug-in DIP switches, you can assemble, position, and mount your
light curtain.
To Do:
1. Remove the red slot cover.
2. Check that the DIP switches on the connection plug-in are set properly.
After setting the DIP switches, you can install the light curtain. Consider
the following when mounting the light curtain:
• Mount both sticks so that the distance of the protective field is at or
greater than the calculated safety distance away from the hazardous
point (see Determine the Safety Distance in publication 450L-UM001).
• Mount both sticks away from any reflective surfaces.
• The sticks must be parallel to each other and be positioned at the
same height.
• Verify that both connection plug-ins are at the same ends of the stick
during installation.
• Confirm that the operating range is between the maximum and
minimum distances show in Table 1 on page 1.
• The optical lens system of transmitter and receiver stick must be in
exact opposition to each other.
• Take suitable measures to reduce vibration (see publication
450L-UM001 for a full range of mounting accessories).
• The safety light curtain must be mounted such that the hazardous
point cannot be reached from below, above, or behind the safety light
curtain and that the light curtain cannot be repositioned.

3. Insert the plug-in.
4. To maintain the IP65 rating, tighten the plug-in screws to (0.38 N•m
[3.36 lb•in], max).
5. Install mounting kit with the standard mounting brackets supplied.
6. Leave brackets slightly loose to allow for alignment adjustments.
Step 4: Wire, apply power, and align system
After your light curtains are mounted, you can wire and power them up to complete
the system alignment.
To Do:
1. Complete the electrical wiring of both sticks (see Table 5).
2. Turn on power to the GuardShield safety light curtain system.
3. Check the STS status indicators on both sticks.
4. Once the STS status indicator on both sticks is steady green, proceed with
system alignment.
a. Rotate the transmitter and receiver sticks while watching the two
Regional Intensity status indicators on the sticks.
b. Find the point where the two indicators for the intensity state
illuminate to a steady green condition.
5. To refine the alignment, determine the maximum left and right adjustment
angles and position each unit at the midpoint, verifying that both Regional
Intensity status indicators are still steady green. To secure the aligned
sticks in position, tighten the mounting brackets to a maximum of 0.7 N•m
[6.19 lb•in] with a torque driver.
6. Cycle power to confirm that the system powers up, goes to the ON state
(STS status indicator steady green), and the intensity status indicators
indicate steady green.
If a 450L-E safety light curtain is used and operated with a
cascading plug-in, see publication 450L-UM001.
IMPORTANT See Typical Wiring Diagrams in publication 450L-UM001 for
examples of how to wire your safety light curtain.

IMPORTANT • For 450L-APU-UN-8 to be used as a transmitter stick, a link
must be made between pins 4 and 8 at the panel. Otherwise,
operation is as a receiver stick by default.
• When 450L-APU-UN-8 is set to be a transmitter, the DIP
switch settings are ignored.
• To mitigate electrical interference, verify that the Earth PE
connection of each plug-in is wired to an appropriate Earth
point.
ATTENTION: Confirmation of a new system configuration is not
required for new systems straight out of the box. However, if
the STS status indicator at the receiver stick displays a
configuration change (blinking red/green), confirmation is
required to proceed. After each reconfiguration of a safety
light curtain, test the system for proper configuration and
operation before placing the guarded machine in operation.
See Confirmation of a New System Configuration in publication
450L-UM001.
The 450L-E sticks have an ILAS system (see 450L-E Integrated Laser
Alignment System (ILAS)).
The 450L-B sticks have no integrated laser alignment system,
however an optional external alignment aid with a mounting clamp
(Cat. No. 450L-ALAT-C) is available.

450L GuardShield Safety Light Curtain Quick Start
450L-E Integrated Laser Alignment System (ILAS)
The 450L-E ILAS system can be switched on/off by placing a finger on the optical
switch, which is the square next to the hand symbol on the front window (see
Figure 4 on page 4). When the laser is activated, several red laser beams are
transmitted from a source close to the optical push button (see Figure 3).
The brightest beam is transmitted perpendicular to the front window, which is also
parallel to the infrared light of the stick. The brightest beam must be positioned at
the opposite stick at the same level as indicated with distance A (Figure 3). An
inverted laser warning symbol has been provided as a convenient target. The other
slanted laser beams must also be targeted between the optics center and the
housing of the opposite stick on the front window. The quantity of slanted beams
on the opposite stick depends on the installation distance. To find optimum
alignment for a 450L-E safety light curtain system, the laser of each stick must be
aligned to the opposite stick.
Figure 3 - Principal Function of the Integrated Laser Alignment System
In a cascading system, each integrated laser system works independently and can
be switched on or off individually.
Step 5: Verify correct operation
450L-B and 450L-E safety light curtain transceiver sticks share a common user
interface (Figure 4). The 450L-E safety light curtain has an additional built-in laser
for alignment and additional indicators for its advanced features.
Figure 4 - Status Indicator Location
To Do:
1. Verify that while the test rod is anywhere within the protective field, the
OSSD safety outputs remain in the OFF-state (OUT is steady red).
2. Move the test rod as shown with a maximum speed of 0.3 ms (11.8 in./s).
3. Verify that the intensity indicator indicates a continuous protective field
interruption (minimum one intensity indicator is OFF) while the test rod is
within the protective field.
LASER LIGHT CLASS 2 HAZARD: Do not stare into the beam.
Each 450L-E safety light curtain has a built-in laser alignment
system. LASER CLASS 2 (IEC 60825-1). Conforms to 21 CFR
1040.10.
For more information on ILAS system use, see publication 450L-UM001.
ATTENTION: After each reconfiguration of a safety light
curtain, test the system for proper configuration and operation
before placing the guarded machine in operation.
