XUSLP Safety Light Curtain
Section 2—Product Description
SYSTEM TYPES
30072-451-29
Rev. 01, 03/2012
XUSLP light curtains are available in two types:
The XUSLPZ system is a microprocessor-controlled, infrared transmittedbeam safety device. The system consists of a receiver assembly and a
transmitter assembly. The transmitter and receiver assemblies are not
physically interconnected.
The XUSLPB system integrates the receiver and transmitter into one
assembly, the transceiver, which is mated with a passive reflector unit. The
passive unit does not require electrical connections.
English
The following terms are used to describe the operating states of the XUSLP
light curtains:
Machine Run
Machine Run is the normal operating state. In the Machine Run state, the
two receiver safety outputs are in the On state, the green machine run
indicator is lit, the diagnostic LEDs display “– –,” and the auxiliary output is
in a state consistent with its configuration (see Table 3 on page 30). The
protected machine is allowed to operate.
Machine Stop
Machine Stop state occurs when a beam is interrupted. In the Machine
Stop state, the two receiver safety outputs are in the Off state, the red
machine stop indicator is lit, the diagnostic LEDs display “– 0,” and the
auxiliary output is in an Off state. The protected machine is not allowed to
operate.
☛
OPERATING STATES
Interlock
Interlock state occurs when the system is in Start Interlock mode (see page
11) and the beam is interrupted. In the Interlock state, the two receiver
safety outputs are in the Off state, the red machine stop and yellow interlock
indicators are lit, the diagnostic LEDs display “– 1,” and the auxiliary output
is in the Off state. When the system is in the Interlock state, the protected
machine is not allowed to operate until the detection zone is clear of
obstructions, and the start button is pressed and released.
Alarm
Alarm state occurs when the system is in Start/Restart Interlock mode (see
page 11) and the beam is interrupted. In the Alarm state, the two receiver
safety outputs are in the Off state, the red machine stop indicator is lit, and
the yellow interlock indicator is flashing. The auxiliary output is in a state
consistent with its configuration (see Table 3 on page 30). The diagnostic
LEDs display a diagnostic code to aid in troubleshooting. When the system
is in the Alarm state, the protected machine is not allowed to operate. The
primary difference between Alarm and Interlock states is that the XUSLP
system will remain in the Alarm state until the fault is corrected, regardless
of power cycling or pressing and releasing the start button.

OPERATING MODES
XUSLP Safety Light Curtain
Section 2—Product Description
The operating mode determines the start-up and operating behavior of the
XUSLP system. The operating mode descriptions in this section draw on the
operating state definitions in “Operating States” on page 10.
Automatic Start
In Automatic Start mode, the system enters the Machine Run state on
startup without operator intervention, as long as the detection zone is not
blocked. When the XUSLP system is powered up in Automatic Start mode,
its safety and auxiliary outputs are Off; if the detection zone is not
obstructed, it enters the Machine Run state (see page 10). In this state,
when the XUSLP system senses an object entering the detection zone, it
changes from Machine Run to Machine Stop (see page 10) state, and
remains in the Machine Stop state until the obstruction is removed. Once
the detection zone is clear, the XUSLP system automatically changes from
Machine Stop to Machine Run.
Start Interlock
When the XUSLP system is powered up in Start Interlock mode, its safety
outputs are Off; if no faults are detected, it enters the Interlock state (see
page 10). To enter the Machine Run state from the Interlock state, the
detection zone must be clear, and then the operator must press and release
the Start button. Once in the Machine Run state, if the XUSLP system
senses an object entering the detection zone, it changes from Machine Run
to Machine Stop state. Once the detection zone is clear, the XUSLP system
automatically changes from Machine Stop to Machine Run state.
Start/Restart Interlock
When the XUSLP system is powered up in Start/Restart Interlock mode,
its safety outputs are Off; if no faults are detected, it enters the Interlock
state. To enter the Machine Run state, the detection zone must be clear,
and then the operator must press and release the Start button. Once in the
Machine Run state, if the XUSLP system senses an object entering the
detection zone, it changes from Machine Run to Machine Stop state. After
the obstruction is removed from the detection zone, the XUSLP system
changes to the Interlock state. To enter the Machine Run state, the operator
must press and release the start button. If any obstruction is present in the
detection zone when the Start button is pressed and released, the XUSLP
system will remain in the Machine Stop state.

The operating mode is selected using the configuration switches inside the
end caps of the receiver/transceiver and the transmitter. To access the
switches, remove the front retaining screw on the end cap. Refer to “Start
Up” on page 29 for configuration instructions. Reinstall the retaining screw
after completing the configuration.

SECTION 3— SAFE MOUNTING DISTANCE
OVERVIEW
WARNING
IMPROPER SETUP
• Install the XUSLP system at the safe mounting distance calculated
using the appropriate formula.
English
• Ensure that the XUSLP system is mounted far enough away from the
operation hazard to fully accommodate the stopping time.
Failure to follow these instructions can result in death or serious
injury.
The XUSLP system must be mounted far enough from the machine danger
zone that the machine will stop before a hand or other body part reaches the
hazardous area. This distance is called the safe mounting distance (see
Figure 2). It is a number calculated from a formula. Before installing the
XUSLP light curtain, you must determine the safe mounting distance.

U.S. SAFE DISTANCE FORMULA
ANSI B11.1
XUSLP Safety Light Curtain
Section 3—Safe Mounting Distance
In the U.S., several formulas are used for determining the safe mounting
distance for a light curtain. For a perimeter access guard, we recommend
the formula provided by the Robotic Industries Association (RIA) through
the American National Standards Institute (ANSI):
DS = K x (Ts + Tc + Tr + Tbm) + Dpf
DS:
The minimum safe distance between the light curtain sensing area
and the nearest point of potential operation hazard.
K:
A hand-speed constant of 63 inches per second. This is the
minimum value accepted by ANSI standards. ANSI recognizes that
this constant may not be optimal, and that the user should consider
all factors before deciding on the value of K for use in the formula.
Ts:
The stopping time of the machine, as measured from the final control
device. Ts is measured at the maximum velocity.
Tc:
The time it takes the control circuit to activate the braking system.
NOTE: Ts and Tc are usually measured together by a stop time
measurement device.
Tr:
The response time of the XUSLP light curtain in seconds. See Table
10 on page 36.
Tbm: The additional time that the brake monitor allows to compensate for
wear and variations in the stopping time. (Brake monitors stop the
machine when the stop time of the machinery exceeds a preset limit.)
NOTE: If a brake monitor is not installed on the machine, a factor
must be added to the measured stop time to include brake wear.
Generally, brake monitors allow approximately 20% to 25%
additional stop time. To determine the actual value, contact the
machine manufacturer.
Dpf:
The maximum travel toward the hazard within the detection zone
that may occur before a stop is signaled. Depth penetration factors
vary depending on the light curtain model and the application.
Dpf is 0.9 m (36 in.) for an application that allows only a person’s arm
to reach through the detection zone—typically a model with three or
more beams. See Figure 3.
Dpf is 1.2 m (48 in.) for an application that allows a person to bend
over the detection zone and reach through it towards the hazard—
typically a two-beam model. See Figure 3.

EUROPEAN SAFE MOUNTING
DISTANCE FORMULA
Multiple Separate Beam Systems
The minimum safe mounting distance discussed in this section is based on
European standard EN 999 and applies to multiple separate beam systems.
It describes the safe mounting distance formula for systems with a minimum
object sensitivity (MOS)1 greater than 70 mm.
When the minimum object sensitivity of the system is greater than 70 mm,
use the following formula to calculate the minimum safe mounting distance:
S = (K x T) + C
Where:
English
S = the minimum safe distance in millimeters between the danger zone and
the detection point, line, plane, or zone.
K = 1600 mm/s
T = the overall system stopping performance in seconds. T = t1 + t2, where:
t1 = the maximum response time of the light curtain in seconds. See
Table 10 on page 36.
t2 = the maximum stopping time of the machine in seconds.
C = 850 mm
So:
S = (1600 mm/s x T) + 850 mm
Perimeter access systems consist of multiple separate beams. These types
of devices are designed for body detection, not torso detection. During the
risk assessment, the following possible scenarios should be taken into
account:
•
•
•
•
Crawling below the lowest beam
Reaching over the top beam
Reaching through two of the beams
Bodily access—intrusion between two beams
Table 1 shows the most practical positions for a 2, 3, and 4-beam system.

300, 600, 900, 1200 mm
3
200, 700, 1100 mm
2
400, 900 mm
If the risk assessment determines that a single beam system is appropriate,
use the following formula for calculating the safe mounting distance:
S = (1600 mm/s x T) + 1200 mm
A height of 750 mm from the reference plane (for example, the floor) is
recommended per EN294:1992 sec. 4.1.1.

14-EN
Minimum object sensitivity (MOS) is the diameter in millimeters of the minimum sized object that
will actuate the light curtain. Minimum object sensitivity is called “detection capability” on the
light curtain nameplate.

WARNING
IMPROPER SETUP
• Read the information in this section completely before starting the
installation procedures beginning on page 21.
• An XUSLP system should only be installed, checked, and maintained by
a qualified person as defined in “Meeting Full Compliance” on
page 5.
• The user must be familiar with the installation requirements, safe
mounting distance, system controls, and features before using the
XUSLP system.
Failure to follow these instructions can result in death or serious
injury.
REFLECTIVE SURFACE INTERFERENCE
A reflective surface—such as a machine part, mechanical guard, or
workpiece—near the detection zone can deflect the optical beam and
prevent an obstruction in the protected zone from being detected. In
Figure 4, for example, the obstruction is not detected because of the
reflection. The reflective object is inside the beam angle.

ADDITIONAL GUARDING
XUSLP Safety Light Curtain
Section 4—Additional Mounting Considerations
Areas of the hazard zone that are not guarded by the XUSLP system must
be protected by another suitable means, such as a point of operation light
curtain, a fixed barrier guard, an interlocked guard, or a safety mat. See
Figure 7.
Example Application

XUSLP Safety Light Curtain
Section 4—Additional Mounting Considerations
When two or more light curtain systems are mounted in close proximity and
in alignment with each other, the transmitters and receivers must be
mounted back-to-back or stacked to prevent one light curtain from
interfering with another. See Figure 8. The XUSLP system has a scan
coding feature to alleviate this kind of system-to-system interference. See
page 19.

The XUSLP scan coding feature allows you to mount light curtain systems
in close proximity and in alignment with each other without interference. The
receiver and transmitter can be set to one of three scan codes—A, B, or C
(see “Start Up” on page 29). The distinctive coding allows the system to
operate without interference while in view of another system with different
scan coding. See Figure 9.
Machine 1
Machine 2
Machine 3
Code A
Code B
Code C
In some cases, a receiver operating in scan code B may react if it receives a
signal from two transmitters operating in scan codes A and C (a single
transmitter operating in scan code A or C will not affect the operation of the
receiver). The receiver operating in scan code B will periodically switch from
Machine Run to Machine Stop state. To prevent this, position the receiver

MOUNTING THE LIGHT CURTAIN
30072-451-29
Rev. 01, 03/2012
NOTE: Before mounting the light curtain, read “Safe Mounting Distance” on
page 12.
To mount the light curtain (refer to Figure 12):
1. If you are installing the light curtain in a high-vibration environment,
install a shock mount kit (G) on the mounting area before mounting the
light curtain. Refer to “Shock Mount Kit” on page 42 to select the kit that
is appropriate for your application.
2. Install the end cap mounting brackets (B) on both ends of the receiver
(C) and transmitter (D) with the mounting hardware (A) provided.
Tighten the hardware to 6 lb-in (0.68 N•m).
English
3. Mount the receiver and the transmitter on the machine in the same plane
and at equal heights. Refer to “Checking the LEDs” on page 32 for
alignment considerations.
NOTE: Alternately, the receiver and transmitter can be mounted on the
optional floor-mounting stands. Refer to “Mounting Accessories” on
page 41.
4. Connect the cables to the receiver and the transmitter. If you have a light
curtain with M12 quick-disconnect cables, the receiver cable end (E) has
an 8-pin connector, and the transmitter cable end (F) has a 5-pin
connector. If you have a cable port version with a terminal block, refer to

START UP
XUSLP Safety Light Curtain
Section 5—Installation
1. Ensure that the power is off. Then, referring to the Configuration section
on page 30, set the light curtain DIP switches as appropriate for the
application. Changes to the DIP switch settings are not effective until the
power is cycled from off to on.
WARNING
UNINTENDED OPERATION
• Turn the power off before adjusting the DIP switches.
Failure to follow these instructions can result in death or serious
injury.
2. Apply power to the system.
3. Check the LEDs as described on page 32.
4. Adjust the alignment of the transmitter and receiver using the yellow
alignment LEDs on the receiver. See “Checking the LEDs” on page 32
and “Troubleshooting” on page 34.
5. If the Yellow LED on the transmitter is illuminated:
a. Realign the transmitter and receiver:
— Alignment of the transmitter and receiver is easiest when the system
is in automatic start operating mode.
— The transmitter and receiver must be in the same plane and at equal
height.
— The transmitter and receiver are aligned when the blocked beam
indicators on the receiver are off.
— Ensure that the alignment position is stable. Verify that a small
deviation of the receiver or transmitter around the alignment position
does not cause the blocked beam indicators to illuminate.
b. Verify that the synchronization beam (see Figure 1 on page 8) is not
obstructed.

Section 6—Troubleshooting
30072-451-29
Rev. 01, 03/2012
SECTION 6— TROUBLESHOOTING
DIAGNOSTIC AND TEST FEATURES
Individual Beam Indicators
XUSLPZ receivers have a red beam indicator next to each infrared beam
(see Figure 1 on page 8), and the XUSLPB transceivers have one beam
indicator next to the receiver beam.
English
The beam indicator illuminates when the associated infrared beam fails to
meet the conditions necessary for the light curtain to remain in the Machine
Run state. When the synchronization beam (see Figure 1 on page 8) is
interrupted, all beam indicators light. The beam indicators are not safety
critical components. A beam indicator failure will not cause an alarm
condition and the XUSLP system will continue to operate.
Synchronization Beam (XUSLPZ Only)
Synchronization between the XUSLPZ transmitter and receiver is optical.
The beam closest to the cable connector supplies the synchronization
signal. When the synchronization beam is blocked, the system enters the
machine stop state, and all individual beam indicators light. When the beam
is cleared, the system resynchronizes and enters a state consistent with its
operating mode.
External Device Monitoring (EDM) or
Machine Primary Control Element
(MPCE) Monitoring
EDM/MPCE monitoring is an important safety function. It monitors the
XUSLP system interface with the guarded machine to ensure that the
machine primary control elements (switching devices, such as contactors)
are responding correctly to the XUSLP light curtains, and to detect any
inconsistency between the two machine primary control elements. To
activate EDM/MPCE monitoring, set position 3 of the Operating Mode
switch located inside the receiver/transceiver end cap. Refer to “Start Up”
on page 29.
Connections for the machine primary control element are made at the
receiver (see Figure 15 on page 26). On power-up, the XUSLP system
looks for the machine primary control element to be in the closed
condition—an Off state where the contacts are closed. When this is found,
the system enters a state consistent with the selected operating mode (see
“Operating Modes” on page 11).
When the XUSLP system enables its safety outputs (enters the Machine
Run state), it monitors the machine primary control element contacts for a
closed-to-open transition. This transition must occur within 300 ms or the
XUSLP system considers the machine primary control element faulted. The
XUSLP system will then enter an Alarm state. Additionally, if the external
device or machine primary control element connectors are incorrectly wired,
the XUSLP system will enter an Alarm state.
Optional Machine Test Signal
(XUSLPZ Only)
34-EN
Some applications require that the machine guarding system be tested by
the machine controller during a non-hazardous portion of the machine cycle
to verify that the guarding system is functioning properly. To provide a
Machine Test Signal (MTS), place a normally closed switch across the MTS
and MTS Return lines of the transmitter. When the transmitter recognizes a
closed-to-open transition on this switch, a beam blocked state is simulated
and the receiver enters the Machine Stop state. The beam blocked state is
simulated as long as the switch is held open. The external MTS contact
must be closed during power-up. If MTS is not used, a jumper must be
installed across MTS and MTS Return. The XUSLPB system does not have
this feature.

GLOSSARY
ANSI: American National Standards Institute. Administrator and coordinator
of the US private sector standardization system.
Detection Zone: The zone within which a specified test piece will be
detected by the XUSLP system.
External Device Monitoring/Machine Primary Control Element
Monitoring (EDM/MPCE): A means by which the light curtain monitors the
state of external control devices.
English
Final Switching Device (FSD): The output of the safety light curtain that
interrupts the machine primary control element (MPCE) as a response to the
output safety switching device (OSSD) transitioning to the OFF state.
Minimum Object Sensitivity (MOS): The diameter in millimeters of the
minimum-sized object that will actuate the light curtain. Minimum object
sensitivity is called “detection capability” on the light curtain nameplate.
OFF State: The state in which the output circuit is interrupted (open) and
does not permit current to flow.
ON State: The state in which the output circuit is complete (closed) and
permits the flow of current.
OSHA: Occupational Safety & Health Administration. A U.S. government
agency.
Output Safety Switching Device (OSSD): The component of the safety
light curtain connected to the machine control system which, when the light
curtain detection zone is interrupted, responds by going to the OFF state.
Also known as a safety output.
Test Object: An opaque cylindrical object used to verify the detection
capability of the XUSLP system.

Section 8—Appendix
TEST PROCEDURE
30072-451-29
Rev. 01, 03/2012
Qualified personnel must perform the test procedure in Table 27 during
initial XUSLP system installation, according to the employer’s regular
inspection program, and after any maintenance, adjustment, or modification
of the XUSLP system or the guarded machine.
Testing ensures that the light curtain, safety system, and the machine
control system work together to properly stop the machine. Failure to test
properly could result in serious injury to personnel. To test the XUSLP
system, use the proper-size test object.
Table 27:
Test Procedure

English
1. Disable the machine to be guarded. Apply power to the XUSLP ❏ Pass
system.
❏ Fail
2. Visually inspect the machine to ensure that access to the danger
point is only through the XUSLP detecting zone. If not, additional
❏ Pass
guarding, including mechanical barriers, may be required. Verify
❏ Fail
that all additional guarding devices and barriers are installed and
operating properly.
3. Verify that the mounting distance of the XUSLP system is equal
to or greater than the calculated minimum safe distance from the
❏ Pass
danger point. See “Safe Mounting Distance” on page 12 for further
❏ Fail
information. Ensure that the operator is not able to stand between
the XUSLP detection zone and the danger point.
4. Check for signs of external damage to the XUSLP system, the
❏ Pass
machine, and the electrical cables and wiring. If damage is found,
❏ Fail
lock the machine off and report the damage to the supervisor.
5. Interrupt the XUSLP system detection zone with the proper-size
test object. Move the test object inside the perimeter (along the top,
sides, and bottom) of the detection zone and up and down through
the center. At least one individual beam indicator must be lit while
❏ Pass
the test object is anywhere in the detection zone. If in automatic
❏ Fail
start mode, verify that the red machine stop LED is lit. If in
start/restart interlock mode, verify that the red machine stop and
yellow interlock LEDs are lit. Press and release the Start button
before proceeding to step 6.
6. Start the machine. While the machine is in motion, interrupt the
detection zone with the test object. The machine should stop
immediately. Never insert the test object into the dangerous parts ❏ Pass
of the machine. With the machine at rest, interrupt the detection
❏ Fail
zone with the test object. Verify that the machine will not start with
the test object in the detection zone.
7. Verify that the braking system is working properly. If the machine
❏ Pass
does not stop fast enough, adjust the braking system or increase
❏ Fail
the distance from the detection zone to the danger point.
8. If the safety devices or the machine fail any of these tests, do not
run the machine. Immediately tag or lock out the machine to
prevent its use, and notify the supervisor.
