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

component (single transceiver). A functional system includes four individual boxes.

Plug-ins are ordered separately from the transceivers.

Figure 1 - Contents of the 450L Transceiver Stick Box

Step 2: Configure the light curtain

The plug-in that is inserted determines the functionality and operating parameters

of 450L. Configuration can be made either directly at the DIP switches or with

software:

• Connected Components Workbench software (450L-E only and requires

450L-AD-OID optical interface device).

• Studio 5000 Logix Designer® application if you use the CIP Safety model.

IMPORTANT This guide provides links to resources for more information

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.

450L GuardShield Safety Light Curtain Quick Start

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.

4Rockwell Automation Publication 450L-QS001A-EN-P - September 2021

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.
