EZ-SCREEN® LS Safety Light Screen
2 Product Overview
EZ-SCREEN LS Safety Light Screen shown without and with the optional EZLSA-K30LGR EZ-LIGHT
Banner EZ-SCREEN LS is a two-piece (emitter and receiver), redundant, microprocessor-controlled, opposed-mode
optoelectronic "light curtain" or "safety light screen". Standard and cascadable models are available in either 14 mm, 23
mm, or 40 mm resolution. Up to four pairs of SLLC.. model emitters and receivers can be cascaded together.
Emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a robust, compact metal
housing. Receivers have a corresponding row of synchronized photodetectors. The sensing field created by the emitter and
receiver is called the "defined area"; its width and height are determined by the length of the sensor pair and the distance
between them. The sensing range spans from 100 mm to 12 m (4 in to 39 ft) for all resolutions, which decreases if corner
mirrors or lens shields are used.
The length of the sensor pair (housing) is dependent on the model; from 280 mm to 1820 mm (11 in to 71.6 in). The end
to end sensing design of the EZ-SCREEN LS, also known as "no blind zone" and "no dead zone," allows mounting with
minimal or no "gaps" in detection.
The EZ-SCREEN LS standard and cascade models have trip output (auto power-up and automatic reset). In typical
operation, if any part of an operator's body (or any opaque object) of more than a pre-determined cross section is
detected, the solid-state output signal switching device (OSSD) safety outputs turn Off. These safety outputs are
connected to the guarded machine's final switching devices (FSDs) that control the machine primary control elements
(MPCEs), which immediately stop the motion of the guarded machine. When the defined area becomes clear, the OSSD
outputs are allowed to turn ON.
EZ-SCREEN LS sensors are extensively FMEA (Failure Mode and Effects Analysis) tested to establish an extremely high
degree of confidence that when properly installed, no system component (even if it should ever fail) can cause a failure to
danger. Because of the due scan technology, EZ-SCREEN LS sensors are also highly immune to EMI, RFI, ambient light,
weld flash, and strobe light.
Eight-conductor EZ-SCREEN LS systems (receivers with 8-pin pigtail QD or flying leads) do not require an external
controller when using the external device monitoring (EDM) function. This function ensures the fault detection capability
required by U.S. Control Reliability and ISO 13849-1 Categories 3 or 4 and PL d or e for controlling final switching devices
(FSDs) or Machine Primary Control Elements (MPCEs).
When configured with a five-conductor hookup, the EZ-SCREEN LS requires a self-checking safety module, safety
controller, or safety PLC/PES that conforms to the level of performance required by the risk assessment. Examples include
the UM-FA-9A/-11A safety module, SC22-3/-3E or XS/SC26-2 safety controller for applications requiring Control Reliability
and/or ISO 13849-1 Categories 3 or 4 and PL d or e.

EZ-SCREEN® LS Safety Light Screen
Electrical connections (power, ground, inputs and outputs) are made via M12 quick-disconnect cordsets or unique RD
(removable disconnect) cordsets, depending on model. A "System" as referred to in this manual, is defined as an emitter
and its receiver, plus their cabling, or to a cascade of emitters and their receivers and their cabling.
Available features include selectable scan code via hookup, an auxiliary fault output, a recessed exit window, and robust
metal housing and end-caps for industry leading durability.
Additional features on cascade models include automatic configuration of up to four sensor pairs (any length or resolution),
optional EZ-LIGHT indication (integral or remotely located) the ability to interface an E-Stop button or Interlocking
switches (hard contacts), and remote fixed blanking. All models require a supply voltage of +24 V dc ±15%.
Both emitter and receiver feature 7-segment Diagnostic Displays and individual LEDs to provide continuous indication of
operating status, configuration and error conditions. An adhesive Diagnostics label is provided that includes a summary of
the operational and error codes. Active Alignment (Segment) Indicators provide beam block information and easier
installation. See Status Indicators on page 54 for more information.
2.1 Appropriate Applications and Limitations
WARNING: Read this Section Carefully Before Installing the System
If all mounting, installation, interfacing, and checkout procedures are not followed properly, the Banner
device cannot provide the protection for which it was designed. The user has the responsibility to
ensure that all local, state, and national laws, rules, codes, or regulations relating to the installation and
use of this control system in any particular application are satisfied. Ensure that all legal requirements
have been met and that all technical installation and maintenance instructions contained in this manual
are followed.
The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the
guarded machine by Qualified Persons1, in accordance with this manual and applicable safety
regulations.
The Banner EZ-SCREEN LS is intended for machine guarding and other safeguarding applications. It is the user’s
responsibility to verify whether the safeguarding is appropriate for the application and is installed, as instructed by this
manual, by a Qualified Person.
The EZ-SCREEN LS ability to perform its safeguarding function depends upon the appropriateness of the application and
upon its proper mechanical and electrical installation and interfacing to the guarded machine. If all mounting,
installation, interfacing, and checkout procedures are not followed properly, the EZ-SCREEN LS cannot provide
the protection for which it was designed.
CAUTION: Install System Only on Appropriate Applications
Banner EZ-SCREEN LS is for use only on machinery that can be stopped immediately after a stop signal
is issued at any point in the machine's stroke or cycle, such as part-revolution clutched machines.
Under no circumstances may the EZ-SCREEN LS be used on full-revolution clutched machinery or in
unsuitable applications as those listed. If there is any doubt about whether or not your
machinery is compatible with the EZ-SCREEN LS, contact Banner Engineering.
2.1.1 Appropriate Applications
EZ-SCREEN LS is typically used for, but is not limited to, the following applications:
•
•
•
•
•
Automated production equipment
Robotic work cells
Molding and power presses
Assembly and packaging machines
Lean manufacturing systems
2.1.2 Examples: Inappropriate Applications
Do not use EZ-SCREEN LS in the following applications:
•
•
With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or fullrevolution) clutched machinery
With any machine with inadequate or inconsistent machine response time and stopping performance
1 A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive knowledge,
training and experience, has successfully demonstrated the ability to solve problems relating to the subject matter and work.

EZ-SCREEN® LS Safety Light Screen
•
•
•
With any machine that ejects materials or component parts through the defined area
In any environment that is likely to adversely affect photoelectric sensing efficiency. For example, corrosive
chemicals or fluids or unusually severe levels of smoke or dust, if not controlled, may degrade sensing efficiency
As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control
system fully comply with the relevant standard or regulation (see OSHA 29CFR1910.217, ANSI/NFPA 79, ANSI
B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
If an EZ-SCREEN LS is installed for use as a perimeter guard (where a pass-through hazard may exist, see Reducing or
Eliminating Pass-Through Hazards on page 15), the dangerous machine motion can be initiated by normal means only
after the safeguarded area is clear of individuals and the safety related part of the control system that is providing the
latching function has been manually reset.
2.1.3 Control Reliability: Redundancy and Self-Checking
Redundancy requires that EZ-SCREEN LS circuit components be backed up to the extent that, if the failure of a single
component will prevent effective machine stopping action when needed, that component must have a redundant
counterpart which will perform the same function. The EZ-SCREEN LS is designed with redundant microprocessors.
Redundancy must be maintained whenever the EZ-SCREEN LS is in operation. Because a redundant system is no longer
redundant after a component has failed, EZ-SCREEN LS is designed to monitor itself continuously. A component failure
detected by or within the self-checking system causes a stop signal to be sent to the guarded machine and puts the EZSCREEN LS into a Lockout condition.
A recovery from this type of Lockout condition requires:
•
•
Replacement of the failed component (to restore redundancy)
The appropriate reset procedure
The Diagnostic Display is used to diagnose causes of a Lockout condition. See Lockout Conditions on page 58.
2.2 Operating Features
The Banner EZ-SCREEN LS models described in this manual feature several functions (depending on model).
2.2.1 Trip Output
The System is configured for Trip Output which allows the System to enter Run mode automatically. Other measures must
be taken to prevent a pass-through hazard; see Reducing or Eliminating Pass-Through Hazards on page 15 and the
warning below for more information.
The OSSD outputs turn ON after power is applied, and the receiver passes its internal self-test/synchronization and
recognizes that all beams are clear. The Trip Output also automatically resets after all beams are cleared.
WARNING: Use of Trip Output
Application of power to the Banner device, the clearing of the defined area, or the reset of an error
condition must not initiate dangerous machine motion. Machine control circuitry must be designed so
that one or more initiation devices must be engaged to start the machine (a conscious act), in addition
to the Banner device entering Run mode. Failure to follow these instructions may result in a
serious bodily injury or death.
2.2.2 External Device Monitoring (EDM)
The External Device Monitoring (EDM) feature allows the EZ-SCREEN LS to monitor the status of external devices, such as
MPCEs. The choices are 1-channel monitoring or no monitoring. EDM is used when the EZ-SCREEN LS OSSD outputs
directly control the MPCEs or other external devices.
This feature is only available with the 8-conductor models.
2.2.3 Fault Output
The current sourcing (PNP) solid-state output (100 mA maximum) is used for control functions that are not safety related;
a typical use is to signal a lockout (fault) to a programmable logic controller (PLC). Available on both the receiver and
emitter, the output provides a fault signal (lockout = On). Interrupting (blocking) the sensing field is not considered a
lockout, so the Fault Output does not change state.
This feature is available only with 8-conductor models.

EZ-SCREEN® LS Safety Light Screen
2.2.4 Scan Code Configuration
Use the scan code to allow operation of multiple pairs of emitters and receivers in close proximity without the effects of
cross-talk. The emitter and receiver may be configured to use one of two scan codes (1 or 2); a receiver recognizes light
only from an emitter with the same scan code. Set the scan code using the wiring on each sensor (see Scan Code Select
on page 38). Both the emitter and its corresponding receiver must have the same setting. Cascaded emitters and
receivers automatically alternate scan codes based on the scan code of the first (master) pair.
This feature is only available with the 8-conductor models.
2.2.5 Wiring Options
Depending on the model, the Machine Interface connection has several options, including:
•
•
•
A 300 mm (1 ft) pigtail cable with an 8-pin M12/Euro-style male quick disconnect (QD)
A 300 mm (1 ft) pigtail cable with a 5-pin M12/Euro-style male quick disconnect (QD)
The Removable Disconnect (RD) that can mate with either a double-ended RD cordset as an interconnect between
cascaded sensors or an 8-wire flying lead RD cordset.
Each connection option is intended for maximum flexibility to solve unique application requirements such as directly
connecting the EZ-SCREEN LS to remotely located safety I/O blocks. For interfacing modules or remotely located safety
I/O blocks where pin 5 of a 5-pin M12 QD is not earth ground, a 4-pin cordset where pin 5 is not physically present or is
not electrically connected can be used (such as MQDEC-406SS double-ended cordset). In such situations, earth ground
must be provided via the mounting brackets.
Additionally, an EZ-SCREEN LS emitter can be connected either to its own power supply or to the receiver cable, color-forcolor. The color-for-color wiring allows the emitter and receiver positions to be interchanged (swapped) without rewiring.

2.2.6 Cascading
Up to four sensor pairs (any length or resolution) can be combined into one system. The cascade system automatically
configures at power up when the terminator plug is installed (pre-installed from factory) or when a standard sensor pair or
an interfacing cordset is used at the end of the series. Double-ended DELS-11xE cordsets are required for connecting
sensors in a cascade.
2.2.7 EZ-LIGHT® Indication
EZ-SCREEN LS cascading models have the ability to connect and remotely locate an EZ-LIGHT or other indicator using a
DELSEF-4xD cordset. Solid-state current sourcing (PNP) outputs (24 V dc at 100 mA) allow for the connection of remote
indicators or other devices for non-safety status information that includes OSSDs ON or OSSDs OFF/Lockout (flashing).
Additionally, EZ-LIGHT model EZLSA-K30LGR (patent pending) is designed to mount directly to the end of a cascade
receiver via the cascade RD connector. The EZLSA-K30LGR provides a replaceable integral solution with a bright 360° red/
green indication.
For the EZ-SCREEN LS standard/stand-alone 8-pin pigtail QD models, a CSB-M128..M1281 splitter cable and optional
DEE2R-8..D double-ended cables can be used with specific models of EZ-LIGHTs at the machine interface connection. The
EZ-LIGHT can be remotely mounted on the machine frame or another convenient mounting surface and provides clear,
360° indication of the EZ-SCREEN LS receiver’s OSSD output status.
See EZ-LIGHTS® for EZ-SCREEN® LS on page 88 for both stand-alone and cascade solutions.

2.2.8 Interfacing an E-Stop Button or Interlocking Switch
EZ-SCREEN LS cascading models can connect electrical (hard) contacts from external devices, such as emergency stop
buttons and interlocking switches, by using an RDLS-8..D cordset. The cascade input may be used to monitor emergency
stop buttons, interlocked gates, or guards and meets or exceeds the requirements for OSHA/ANSI control reliability and up
to Category 4 PLe, per ISO 13849-1.
2.2.9 Remote Fixed Blanking
On cascade models, fixed blanking is available to, in effect, "disable" beams that would otherwise be continually blocked
by a stationary object. One or multiple areas within an EZ-SCREEN LS sensor pair may be "blanked out," with a minimum
of one beam between two blanked areas. The first sensing beam (CH1 synchronization beam) at the display end of sensor
must remain clear (cannot be blanked); any other beam may be blanked. All beams of a fixed blanked area must remain
blocked during operation in order for the OSSDs to remain ON.
The Remote Fixed Blanking feature can be used on an EZ-SCREEN LS cascade receiver as a stand-alone system or in a
cascaded system. A DELSEF-81D cordset used with a EZA-RBK-1 Remote Blanking Key Switch or a RDLS-8..D cordset with
a user-supplied switch and indicator provides a convenient means to program the blanked area. The remote programming
is effective on all receivers in the cascaded systems (for example, multiple areas can be blanked on different sensor pairs).
2.2.10 Status Indicators
Status indicators on both the emitter and receiver are visible on each sensor's front panel.

3 Mechanical Installation
The EZ-SCREEN LS system performance as a safety guarding device depends on:
•
•
The suitability of the application
The proper mechanical and electrical installation and interfacing to the guarded machine
WARNING: Read this Section Carefully Before Installing the System
If all mounting, installation, interfacing, and checkout procedures are not followed properly, the Banner
device cannot provide the protection for which it was designed. The user has the responsibility to
ensure that all local, state, and national laws, rules, codes, or regulations relating to the installation and
use of this control system in any particular application are satisfied. Ensure that all legal requirements
have been met and that all technical installation and maintenance instructions contained in this manual
are followed.
The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the
guarded machine by Qualified Persons2, in accordance with this manual and applicable safety
regulations.
3.1 Mechanical Installation Considerations
The two primary factors that influence the layout of the EZ-SCREEN LS system mechanical installation are the Safety
Distance (Minimum Distance) (see Calculating the Safety Distance (Minimum Distance) on page 13) and the
supplemental safeguarding/eliminating pass-through hazards (see Reducing or Eliminating Pass-Through Hazards on page
15). Other considerations include:
• Emitter and Receiver Orientation on page 19
• Adjacent Reflective Surfaces on page 17
• Use of Corner Mirrors on page 18
• Installation of Multiple Systems on page 20
WARNING: Position Components Carefully
The emitter and receiver must be positioned such that the hazard cannot be accessed by
reaching over, under, around, or through the sensing field. Additional and supplemental guarding
may be required.
3.1.1 Calculating the Safety Distance (Minimum Distance)
Safety Distance (Ds), also called Minimum Distance (S), is the minimum distance required between the defined area and
the closest reachable hazard point. The distance is calculated so that when an object or a person is detected (by blocking a
sensing beam), the EZ-SCREEN LS sends a stop signal to the machine, causing it to stop by the time the object or person
can reach any machine hazard point.
The distance is calculated differently for U.S. and European installations. Both methods take into account several factors,
including a calculated human speed, the total system stopping time (which itself has several components), and the depth
penetration factor. After the distance has been determined, record the calculated distance on the Daily Checkout Card.
WARNING: Safety Distance (Minimum Distance)
The Banner emitters and receivers must be mounted at a distance from the nearest hazard such that an
individual cannot reach the hazard before cessation of hazardous motion or situation. This distance can
be calculated using the formulas in this section, as described by ANSI B11.19 and ISO 13855, and must
be greater than 100 mm (4 in) regardless of calculated value. Failure to establish and maintain the
minimum distance may result in serious bodily injury or death.

Notes:
1. The OSHA-recommended hand speed constant K has been determined by various studies and, although
these studies indicate speeds of 1600 mm/sec. (63 in/sec.) to more than 2500 mm/sec. (100 in/sec.),
they are not conclusive determinations. Consider all factors, including the physical ability of the operator,
when determining the value of K to be used.
2. The recommended hand speed constant K, derived from data on approach speeds of the body or parts of
the body as stated in ISO 13855.
3. Ts is usually measured by a stop-time measuring device. If the machine manufacturer's specified stop
time is used, at least 20% should be added to allow for possible clutch/ brake system deterioration. This
measurement must take into account the slower of the two MPCE channels, and the response time of all
devices or controls that react to stop the machine.

point on the guarded machine.
Mount the EZ-SCREEN LS emitter and receiver so that no part of the
defined area will be closer than 602 mm to the closest reachable hazard
point on the guarded machine.
WARNING: Determine Correct Stop Time
Stop time (Ts) must include the response time of all devices or controls that react to stop the
machine. If all devices are not included, the calculated safety distance (Ds or S) will be too short. This
can lead to serious bodily injury or death. Be sure to include the stop time of all relevant devices and
controls in your calculations.
If required, each of the two Machine Primary Control Elements (MPCE1 and MPCE2) must be capable of
immediately stopping the dangerous machine motion, regardless of the state of the other. These two
channels of machine control need not be identical, but the stop time performance of the machine (Ts,
used to calculate the safety distance) must take into account the slower of the two channels.
3.1.2 Reducing or Eliminating Pass-Through Hazards
A pass-through hazard is associated with applications where personnel may pass through a safeguard (which issues a stop
command to remove the hazard), and then continues into the guarded area, such as in perimeter guarding. Subsequently,
their presence is no longer detected, and the related danger becomes the unexpected start or restart of the machine while
personnel are within the guarded area.
In the use of light screens, a pass-through hazard typically results from large safety distances calculated from long
stopping times, large minimum object sensitivities, reach-over, reach-through, or other installation considerations. A passthrough hazard can be generated with as little as 75 mm (3 in) between the defined area and the machine frame or hard
(fixed) guarding.
Eliminate or reduce pass-through hazards whenever possible. While it is recommended to eliminate the pass-through
hazard altogether, this may not be possible due to machine layout, machine capabilities, or other application
considerations.
One solution is to ensure that personnel are continually sensed while within the hazardous area. This can be accomplished
by using supplemental safeguarding, such as described by the safety requirements in ANSI B11.19 or other appropriate
standards.
An alternative method is to ensure that once the safeguarding device is tripped it will latch and will require a deliberate
manual action to reset. This method of safeguarding relies upon the location of the reset switch as well as safe work
practices and procedures to prevent an unexpected start or restart of the guarded machine.
WARNING: Use of the Banner device for Perimeter Guarding
If a Banner device is installed in an application that results in a pass-through hazard (for example,
perimeter guarding), either the Banner device System or the Machine Primary Control Elements
(MPCEs) of the guarded machine must cause a Latched response following an interruption of the
defined area.
The reset of this Latched condition may only be achieved by actuating a reset switch that is separate
from the normal means of machine cycle initiation.
Lockout/Tagout procedures per ANSI Z244.1 may be required, or additional safeguarding, as described
by ANSI B11.19 safety requirements or other appropriate standards, must be used if a passthrough
hazard cannot be eliminated or reduced to an acceptable level of risk. Failure to observe this
warning may result in serious bodily injury or death.

EZ-SCREEN® LS Safety Light Screen
3.1.3 Supplemental Safeguarding
As described in Calculating the Safety Distance (Minimum
Distance) on page 13, the EZ-SCREEN LS must be properly
positioned such that an individual cannot reach through the
defined area and access the hazard point before the
machine has stopped.
Additionally, the hazard cannot be accessible by reaching
around, under, or over the defined area. To accomplish
this, supplemental guarding (mechanical barriers, such as
screens or bars), as described by ANSI B11.19 safety
requirements or other appropriate standards, must be
installed. Access will then be possible only through the
defined area of the EZ-SCREEN LS System or through other
safeguarding that prevents access to the hazard (see Figure
10 on page 16).
The mechanical barriers used for this purpose are typically
called "hard (fixed) guarding"; there must be no gaps
between the hard (fixed) guarding and the defined area.
Any openings in the hard (fixed) guarding must comply with
the safe opening requirements of ANSI B11.19 or other
appropriate standard.
Figure 10. An example of supplemental safeguarding
Figure 10 on page 16 shows an example of supplemental safeguarding inside a robotic work cell. The EZ-SCREEN LS, in
conjunction with the hard (fixed) guarding, is the primary safeguard. Supplemental safeguarding (such as a horizontalmounted safety light screen as an area guard) is required in areas that cannot be viewed from the reset switch (for
example, behind the robot and the conveyor). Additional supplemental safeguarding may be required to prevent clearance
or trapping hazards (for example, a safety mat as an area guard between the robot, the turntable, and the conveyor).
WARNING: The Hazard Must Be Accessible Only through the Defined Area
The installation of the EZ-SCREEN LS must prevent any individual from reaching around, under, over or
through the defined area and into the hazard without being detected. Mechanical barriers (for example,
hard (fixed) guarding) or supplemental safeguarding may be required to comply with this requirement,
and is described by ANSI B11.19 safety requirements or other appropriate standards.
3.1.4 Reset Switch Location
The EZ-SCREEN LS with a trip output (auto power-up and automatic reset) will turn the OSSD outputs ON when the
defined area is unobstructed (clear). Per application requirements, a latch response requiring a manual reset to a powerup condition or after an interruption has cleared the defined area might be required. The latch function can be provided by
interfacing the EZ-SCREEN LS OSSD outputs to the machine's safety-related control system, a safety controller (such as
SC22-3 or XS/SC26-2), or safety module (such as the UM-FA-9A/11A).
The system or device providing the latch/reset function must conform to the level of performance required by the risk
assessment. In applications requiring Control Reliability and/or ISO 13849-1 Categories 3 or 4 and PL d or e, it is
recommended that a monitored manual reset (for example, open-closed-open action), such that a shorted or tied-down
button cannot cause a reset be used.
The reset switch must be mounted at a location that complies with the warning and guidelines below. If any
hazardous areas are not in view from the switch location, additional means of safeguarding must be provided. The switch
should be protected from accidental or unintended actuation (for example, through the use of rings or guards).
A key-actuated reset switch provides some operator or supervisory control, as the key can be removed from the switch
and taken into the guarded area. However, this does not prevent unauthorized or inadvertent resets due to spare keys in
the possession of others, or additional personnel entering the guarded area unnoticed. When considering where to locate
the reset switch, follow the guidelines below.
16
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
WARNING: Reset Switch Location
When considering where to locate the reset switch, you must follow the guidelines outlined in this
section.
If any areas within the guarded area are not visible from the reset switch, additional safeguarding must
be provided, as described by the ANSI B11.19 series or other appropriate standards.
Failure to follow these instructions could result in serious injury or death.
All reset switches must be:
•
•
•
•
Outside the guarded area
Located to allow the switch operator a full, unobstructed, view of the entire guarded area while the reset is
performed
Out of reach from within the guarded area
Protected against unauthorized or inadvertent operation (such as through the use of rings or guards).
Important: Resetting a safeguard must not initiate hazardous motion. Safe work procedures require a
start-up procedure to be followed and the individual performing the reset to verify that the entire
hazardous area is clear of all personnel before each reset of the safeguard is performed. If any area
cannot be observed from the reset switch location, additional supplemental safeguarding must be used:
at a minimum, visual and audible warnings of machine start-up.
3.1.5 Adjacent Reflective Surfaces
WARNING: Avoid Installation Near Reflective Surfaces
Avoid locating the defined area near a reflective surface; it could reflect sensing beam(s) around an
object or person within the defined area, and prevent its detection by the EZ-SCREEN LS. Perform the
trip test, as described in the manual, to detect such reflection(s) and the resultant optical short circuit.
Failure to prevent reflection problems will result in incomplete guarding and could result in
serious injury or death.
A reflective surface located adjacent to the defined area may deflect one or more beams around an object in the defined
area. In the worst case, an optical short circuit may occur, allowing an object to pass undetected through the defined area.
This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the
floor, or the walls. Beams deflected by reflective surfaces are discovered by performing the trip test and the periodic
checkout procedures. To eliminate problem reflections:
•
•
•
•
If possible, relocate the sensors to move the beams away from the reflective surface(s), being careful to maintain
adequate separation distance
Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reflectivity
Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resolution
resulting from the optical short circuit and use the corresponding depth penetration factor (Dpf or C) in the Safety
Distance (Minimum Distance) formula; or mount the sensors in such a way that the receiver's field of view and/or
the emitter's spread of light are restricted from the reflective surface
Repeat the trip test (see Trip Test on page 34) to verify that these changes have eliminated the problem
reflection(s). If the workpiece is especially reflective and comes close to the defined area, perform the trip test with
the workpiece in place

3.1.6 Use of Corner Mirrors
EZ-SCREEN LS may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow
undetected personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum
specified emitter/receiver separation by approximately 8 percent per mirror, as follows:

8.6 m (28 ft)
If mirrors are used, the difference between the angle of incidence from the emitter to the mirror and from the mirror to
the receiver must be between 45° and 120° (see Figure 12 on page 19). If placed at a sharper angle, an object in the
light screen may deflect beam(s) to the receiver, preventing the object from being detected, also know as false proxing.
Angles greater than 120° result in difficult alignment and possible optical short circuits.
WARNING: Avoid Retroreflective Installation
Do not install emitters and receivers in "retroreflective" mode, with less than a 45° angle of incidence,
as shown. Sensing may be unreliable in this configuration and result in a serious bodily injury
or death.

3.1.7 Emitter and Receiver Orientation
The emitter and receiver must be mounted parallel to each other and aligned in a common plane, with both machine
interface cable ends pointing in the same direction. Never mount the emitter with its machine interface cable end oriented
in the opposite direction of the cable end of the receiver. If this occurs, voids in the light screen may allow objects or
personnel to pass through the defined area undetected.
The emitter and receiver may be oriented in a vertical or horizontal plane, or at any angle between horizontal and vertical,
as long as they are parallel to each other and their cable ends point in the same direction. Verify that the light screen
completely covers all access to the hazard point that is not already protected by hard (fixed) guarding or other
supplemental guarding.
WARNING: Proper Orientation of System Emitters and Receivers
EZ-SCREEN LS emitters and receivers must be installed with their corresponding cabled ends pointing in
the same direction (for example, both cabled ends facing up). Failure to orient them properly will
impair the performance of the EZ-SCREEN LS System and will result in incomplete guarding,
and could result in serious bodily injury or death.

3.1.8 Installation of Multiple Systems
Whenever two or more EZ-SCREEN LS emitter and receiver pairs are adjacent to one another, optical crosstalk may take
place between the systems. To minimize optical crosstalk, alternate the positions of the emitters and receivers (see Figure
15 on page 21).
When three or more systems are installed in the same plane (as shown in Figure 15 on page 21), optical crosstalk may
occur between sensor pairs whose emitter and receiver lenses are oriented in the same direction. In this situation,
eliminate optical crosstalk by mounting these sensor pairs exactly in line with each other within one plane, or by adding a
mechanical barrier between the pairs.
To further aid in avoiding crosstalk, the sensors feature two selectable scan codes. A receiver set to one scan code will not
respond to an emitter set to another code.

WARNING: Multiple Pairs of Sensors
Do not connect multiple pairs of sensors to one Interface Module (for example, IM-T-9A/-11A) or
otherwise parallel OSSD outputs. Connection of multiple OSSD safety outputs to a single device
may result in serious bodily injury or death, and is prohibited.
WARNING: Scan Code
In situations where multiple systems are mounted closely together, or where a secondary emitter is in
view (within ±5°) and within range of an adjacent receiver, the adjacent systems must be configured
for different Scan Codes (one system set for Scan Code 1 and the other for Scan Code 2). If not, a
receiver may synchronize to the signal from the wrong emitter, reducing the safety function of the light
screen. This situation is discovered by performing the trip test.
3.2 Mounting System Components
3.2.1 Mounting Hardware
After the mechanical layout consideration of Mechanical Installation Considerations are addressed, mount the sensors and
route the cables.

Emitter/receiver pairs can be spaced from 0.1 m (4 in) to 12 m (39 ft) apart. This distance is reduced if corner mirrors are
used.
Each sensor ships with two EZLSA-MBK-11 end-mount brackets. Emitters and receivers 980 mm and longer also include
one EZLSA-MBK-12 center-mount bracket. The supplied end-mount brackets allow ±23° rotation, can be mounted with
flange out or flange in, and in 90° increments. EZLSA-MBK-12 center-mount brackets allow 30° rotation in one direction
and 15° in the other (see Mounting the end-mount Brackets and Mounting Side-Mount Brackets). Center- and side-mount
brackets allow "no blind zone" mounting with minimal or no "gaps" in detection. If additional rotation is required, see the
available accessory brackets.
The supplied EZLSA-MBK-12 or optional EZLSA-MBK-16 side-mount bracket must be used with longer sensors if they are
subject to shock or vibration. In such situations, the sensors are designed to be mounted with up to 910 mm unsupported
distance (between brackets). Sensors 980 mm and longer are supplied with one additional center-mount bracket.

4 Electrical Installation and Testing
WARNING: Read this Section Carefully Before Installing the System
If all mounting, installation, interfacing, and checkout procedures are not followed properly, the Banner
device cannot provide the protection for which it was designed. The user has the responsibility to
ensure that all local, state, and national laws, rules, codes, or regulations relating to the installation and
use of this control system in any particular application are satisfied. Ensure that all legal requirements
have been met and that all technical installation and maintenance instructions contained in this manual
are followed.
The user has the sole responsibility to ensure that this Banner device is installed and interfaced to the
guarded machine by Qualified Persons4, in accordance with this manual and applicable safety
regulations.
The following are the main steps to electrically install the EZ-SCREEN LS components and interface with the guarded
machine:
1. Routing cordsets and making initial electrical connections (see Routing Cordsets on page 27 and Initial Electrical
Connections on page 28).
2. Apply power to each emitter/receiver pair (see Initial Electrical Connections on page 28).
3. Perform an Initial Checkout Procedure (see Initial Checkout Procedure on page 28).
4. Make all electrical interface connections to the guarded machine (see Electrical Connections to the Guarded
Machine on page 35).
5. Perform a commissioning checkout procedure (see Commissioning Checkout on page 63).
4.1 Routing Cordsets
Attach the required cordsets to the sensors, and route the sensor cables to the junction box, electrical panel, or other
enclosure in which the interface module, the redundant mechanically linked interposing relays, FSDs, or other safetyrelated parts of the control system are located. This must be done per local wiring code for low-voltage dc control cables
and may require installation of electrical conduit. See Cordsets on page 77 for selection of Banner supplied cables.
EZ-SCREEN LS is designed and manufactured to be highly resistant to electrical noise and to operate reliably in industrial
settings. However, extreme electrical noise may cause a random Trip condition; in extreme cases, a Lockout is possible.
Emitter and receiver wiring is low voltage; routing the sensor wires alongside power wires, motor/servo wires, or other
high voltage wiring may inject noise into the EZ-SCREEN LS System. It is good wiring practice, and sometimes may be
required by code, to isolate emitter and receiver cables from high-voltage wires, avoid routing cables close to “noisy”
wiring, and provide a good connection to earth ground.
Sensor cabling and any interconnect wiring should have an insulation temperature rating of at least 90 °C (194 °F).
Installation/Replacement of RD Cordsets— To remove the Removable Disconnect (RD) cordset, unscrew the two
Phillips screws and carefully pull the connector straight back. To install an RD Cordset:
1. Slide the RD connector firmly into housing's RD port. (Ensure rectangular gasket is installed.)
2. Tighten the Phillips screws at base of connector to lock into place. Do not over tighten.
NOTE: The machine interface cable must connect to the sensor end adjacent to the indicators for the
system to operate properly.

NOTE: Emitter and receiver power (current) requirements are accounted for. The above values
represent additional current draw that must be accounted for because of the load current.
NOTE: Maximum cordset lengths are intended to ensure that adequate power is available to the EZSCREEN LS when the supply is operating at +20 V dc. Values in the previous table are worse case.
Contact banner Engineering if there are any questions.
NOTE: The length of Emitter machine interface cordsets can be two times longer than those listed for
the receiver in the table above if a CSB Splitter cordset is not used. If a CSB Splitter cordset is used,
connect one branch of the CSB splitter to the receiver and other branch to the emitter via DEE2R
double-ended cordset up to the same length listed in the table above.
4.2 Initial Electrical Connections
WARNING: Proper Electrical Hookup
Electrical hookup must be made by Qualified Personnel and must comply with NEC (National Electrical
Code) and local standards. Make no more connections to the EZ-SCREEN LS System than are
described in this manual. Connection of other wiring or equipment to the EZ-SCREEN LS
System could result in serious bodily injury or death.
Lockout/tagout procedures may be required (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate
standard for controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC,
NFPA79 or IEC60204-1, always connect the earth ground (green/yellow wire). Do not operate the EZ-SCREEN LS
without an earth ground connection.
Make the electrical connections in the order described in this section. Do not remove end-caps; no internal connections are
to be made. All connections are made through the RD or pigtail QD connections.
Emitter Cordset
EZ-SCREEN LS emitters have either a 5-pin or 8-pin cordset, but not all conductors are used. The other wires are
in place to allow a parallel connection (color-for-color) to the receiver cable, providing sensor interchangeability
(or “swapability”); either sensor may be installed at either cordset connection. In addition to providing similar
cabling, this wiring scheme is advantageous during installation, wiring, and troubleshooting.
Receiver Cordset—5-pin
Do not connect any wires to the machine control circuits (OSSD outputs) at this time.
Receiver Cordset—8-pin
Do not connect any wires to the machine control circuits (OSSD outputs) at this time. For the initial
power-up and checkout, External Device Monitoring (EDM) must be configured/wired (see External Device
Monitoring on page 37), the Scan Code must be selected (see Scan Code Select on page 38), and the Fault
Output can be connected (see Fault Output on page 9). Take precautions to prevent unused wires from shorting to
ground or to other sources of energy (for example, terminate with a wire-nut). Final OSSD wiring must be
completed later.
4.3 Initial Checkout Procedure
The initial checkout procedure must be performed by a Qualified Person. It must be performed only after configuring the
System and after connecting the emitter and receiver.
The procedure is performed on two occasions:
•
•
To ensure proper installation when the System is first installed
To ensure proper System function whenever any maintenance or modification is performed on the System or on
the machinery that is guarded by the System.
4.3.1 Configuring the System for Initial Checkout
For the initial checkout, the EZ-SCREEN LS System must be checked without power available to the guarded machine.
Final interface connections to the guarded machine cannot take place until the light screen system has been checked out.
This may require lockout/tagout procedures (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate
standard for controlling hazardous energy). The OSSD connections will be made after the initial checkout procedure has
been successfully completed.
7 Assumes L2 and L4 are 1 ft and L3 is 50 ft.
28
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
Verify that:
• Power has been removed from (or is not available to) the guarded machine and its controls or actuators
• The machine control circuit or the Safety/Interface Module is not connected to the OSSD outputs at this time
(permanent connections will be made later)
• EDM is configured and wired per application requirements (1-channel or no monitoring, see External Device
Monitoring on page 37)
4.3.2 Initial Power-Up
1. Inspect the area near the light screen for reflective surfaces, including work pieces and the guarded machine.
Reflective surfaces may cause light beams to reflect around a person in the light screen, preventing the person
from being detected and not stopping the machine motion (see Adjacent Reflective Surfaces on page 17).
2. Eliminate the reflective surfaces as much as possible by relocating, painting, masking, or roughening them.
Remaining problem reflections will become apparent during the trip test.
3. Verify that power is removed from the EZ-SCREEN LS System and from the guarded machine and that the
OSSD safety outputs are not connected.
4. Remove all obstructions from the light screen.
5. With the power to the guarded machine Off, make external device monitoring (EDM), power, and earth ground
connections on both the emitter and receiver cables (see Reference Wiring Diagrams on page 39). The +24 V dc
(brown wire) and 0 V dc (blue wire) should be connected to a SELV-rated supply and GND (green/yellow wire) to
earth ground. If the installation does not allow direct connection to earth ground via the cordset, the earth ground
must be provided via the mounting brackets.
6. Power up the EZ-SCREEN LS System only.
7. Verify that the input power is present to both the emitter and the receiver. At least one indicator on both the
emitter and the receiver should be On and the start-up sequence should cycle.
8. Watch both the emitter and the receiver Status indicators and the receiver Alignment indicators to determine the
light screen alignment status:
• An Emitter Lockout Condition—the emitter Status indicator is single-flashing red; the receiver Status
indicator is solid red, and the receiver's 7-segment display reads CH1.
• A Receiver Lockout Condition—the receiver Status indicator is single-flashing red, with Alignment and
Run mode indicators Off, and the receiver 7-segment display shows an Error Code.
• Normal Operating Mode (emitter)—the Status indicator is solid green.
• Clear (Run) Condition (receiver)—the Status indicator is solid green, and the Run mode indicator is
solid amber. All Alignment indicators are solid green.
• A Blocked Condition (receiver)—The Status indicator is solid red, Run mode indicator is solid amber, one
or more Alignment indicator(s) are solid red, identifying the location of the blocked beams, and the number
of blocked beams is displayed.
NOTE: If beam 1 is blocked, the Alignment indicator 1 will be red and all others Off.
Beam 1 provides the synchronization signal.
9. Proceed to Optical Alignment on page 29.
4.3.3 Optical Alignment
CAUTION: Ensure that no individuals are exposed to any hazard if the OSSD outputs turn ON
when the emitter and receiver become aligned.
Verify the optimal alignment, adjusting the sensor rotation with the power on:
1. Verify that the emitter and the receiver are pointed squarely at each other. Use a straight edge (for example, a
level) to determine the direction the sensor is facing. The sensor face must be perpendicular to the optical axis.

2. Turn on the power to the emitter and receiver. If the Channel #1 beam is not aligned, the Status and Alignment
indicator 1 will be red, the Run mode indicator will be off, and the 7-segment display sequentially indicates CH1.
All the Alignment indicators (2-n) will be off.

3. If the green Status and amber Run mode indicators are on, go to the next step. If not, rotate each sensor (one at a
time) left and right until the green Status indicator is on. (As the sensor rotates out of alignment, the red Status
indicator turns on). As more beams are aligned, the Alignment indicators turn from red to green and the number of
blocked beam indicators decreases.

repeat with the other sensor. Center each sensor between those two positions and tighten the mounting screws,
making sure to maintain the positioning as the screws are tightened.

4.3.4 Optical Alignment Procedure with Mirrors
EZ-SCREEN LS sensors may be used with one or more corner mirrors for guarding more than one side of an area. The
MSM-... and SSM-... rear-surface glass mirrors are rated at 85% efficiency. Thus, excess gain and sensing range are
reduced when using mirrors; see Use of Corner Mirrors on page 18.
During any adjustments, allow only one individual to adjust any one item at any one time.
In addition to the standard optical alignment procedure, verify:
1. The emitter, receiver, and all mirrors are level and plumb.
30
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
2. The middle of the defined area and the center point of the mirrors are approximately the same distance from a
common reference point, such as the same height above a level floor.
3. There are equal amounts of mirror surface above and below the defined area such that the optical beams are not
passing below or above the mirror.
NOTE: A LAT-1-SS Laser Alignment Tool is very helpful by providing a visible red dot along the optical
axis. See Figure 23 on page 31 and Banner Safety Applications Note SA104 (p/n 57477) for further
information.

4.3.5 Remote Fixed Blanking
On cascade models, fixed blanking is available to, in effect, "disable" beams that would otherwise be continually blocked
by a stationary object. One or multiple areas within an EZ-SCREEN LS sensor pair may be "blanked out," with a minimum
of one beam between two blanked areas. The first sensing beam (CH1 synchronization beam) at the display end of sensor
must remain clear (cannot be blanked); any other beam may be blanked. All beams of a fixed blanked area must remain
blocked during operation in order for the OSSDs to remain ON.
The Remote Fixed Blanking feature can be used on an EZ-SCREEN LS cascade receiver as a stand-alone system or in a
cascaded system. A DELSEF-81D cordset used with a EZA-RBK-1 Remote Blanking Key Switch or a RDLS-8..D cordset with
a user-supplied switch and indicator provides a convenient means to program the blanked area. The remote programming
is effective on all receivers in the cascaded systems (for example, multiple areas can be blanked on different sensor pairs).
Programming Key Switch Location
The EZA-RBK-1 or an SPDT (Form C) switch is required to perform the remote programming procedure, as shown. A keyactuated switch provides some supervisory control since the key can be removed from the switch. The Programming Key
Switch must be:
• Located outside the guarded area
• Located to allow the switch operator full unobstructed view of the entire defined area
• Protected against unauthorized or inadvertent operation
WARNING: Use of Fixed Blanking.
Use Fixed Blanking only when necessary. Any holes created in the defined area either must be
completely filled by the blanked object or the safety (minimum) distance must be increased to account
for the larger resolution (see Calculating the Safety Distance (Minimum Distance) on page 13).

Remote Fixed Blanking Programming Procedures
Prior to performing these procedures, install the EZ-SCREEN LS per Mechanical Installation on page 13 of this document.
Align the emitter/receiver pair and perform all required checkout procedures to ensure proper operation. Ensure that the
EZA-RBK-1 programming key switch is rotated to the counter-clockwise Run position at power-up and normal operation.
Important:
1. The first sensing beam (CH1 synchronization beam) at the display end of the sensor must
remain clear during normal operation.
2. The number and location of blocked beams is indicated by the receiver’s 7-segment display and
the alignment indicators. If the configuration is reliable, this number should not change.
Initial programming—no fixed blanking previously programmed, perform the following: The following procedures
must be completed within 10 minutes or a lockout occurs (Error Code 12 displays).
Action

Comments
The number of blocked beams should
not change if all beams to be blanked
are reliably obstructed. If the number
changes, some beams may be partially
or intermittently blocked, which may
cause a lockout condition during
operation.
This teaches and saves the new fixed
blanking configuration.

4.3.6 Trip Test
After optimizing the optical alignment and configuring fixed blanking (if applicable), perform the trip test to verify the
detection capability of the EZ-SCREEN LS System. This test also verifies correct sensor orientation and identifies optical
short circuits. After the installation has passed the trip test, the safety outputs may be connected and the commissioning
checkout may be performed (initial installations only).
1. Select the proper test piece (see Table 4 on page 34), supplied with the receiver.

2. Verify that the System is in Run mode, the Green Status indicator is On, all Alignment indicators are green, and the
amber Status indicator is On.
3. Pass the specified test piece through the defined area in three paths: near the emitter, near the receiver, and
midway between the emitter and receiver.
Emitter
Test Piece
Receiver
Figure 26. Trip Test
4. During each pass, while the test piece is interrupting the defined area, at least one Alignment indicator must
be Red. The Red Alignment indicator must change with the position of the test piece within the defined
area.
If all Alignment indicators turn green or fail to follow the position of the test piece while it is within the defined
area, the installation has failed the trip test. Check for correct sensor orientation and reflective surfaces.
When the test piece is removed from the defined area, in trip output operation, the green Status indicator must
turn on .
WARNING: If Trip Test Indicates a Problem
If the EZ-SCREEN LS System does not respond properly to the trip test, do not attempt to use
the System. If this occurs, the System cannot be relied on to stop dangerous machine motion
when a person or object enters the defined area. Serious bodily injury or death could
result.
5. If mirrors are used in the application: Test the defined area on each leg of the sensing path (for example, emitter
to mirror, between mirror and receiver, see Figure 27 on page 35).

Machine on page 35.
4.4 Electrical Connections to the Guarded Machine
Verify that power has been removed from the EZ-SCREEN LS and the guarded machine. Make the permanent electrical
connections as described in OSSD Output Connections on page 35 and FSD Interfacing Connections on page 36 as
required by each individual application.
Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, ISO 14118, or the appropriate
standard for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC,
NFPA79 or IEC 60204-1.
Supply power and external device monitoring (EDM) should already be connected. The EZ-SCREEN LS must also have been
aligned and passed the Initial Checkout, as described in Initial Checkout Procedure on page 28.

CAUTION: Shock Hazard
Always disconnect power from the Banner device and the guarded machine before making any
connections or replacing any component. Use extreme caution to avoid electrical shock at all
times.
4.4.1 OSSD Output Connections
Refer to the output specifications in the Receiver Specifications (see Specifications on page 65) and the warning below
before making OSSD output connections and interfacing the EZ-SCREEN LS to the machine.
WARNING: Interfacing of Both OSSDs
Both OSSD (Output Signal Switching Device) outputs must be connected to the machine control so that
the machine’s safety-related control system interrupts the circuit to the machine primary control
element(s), resulting in a non-hazardous condition.
Never wire an intermediate device(s) (for example, PLC, PES, or PC) that can fail in such a manner that
there is the loss of the safety stop command, OR in such a manner that the safety function can be
suspended, overridden, or defeated, unless accomplished with the same or greater degree of safety.
www.bannerengineering.com - Tel: 763.544.3164
35
EZ-SCREEN® LS Safety Light Screen
WARNING: OSSD Interfacing
To ensure proper operation, the Banner device output parameters and machine input parameters must
be considered when interfacing the Banner device OSSD outputs to machine inputs. Machine control
circuitry must be designed so that the maximum load resistance value is not exceeded and that the
maximum specified OSSD Off-state voltage does not result in an On condition.
Failure to properly interface the OSSD Outputs to the guarded machine may result in serious
bodily injury or death.
4.4.2 FSD Interfacing Connections
FSDs (Final Switching Devices) take many forms. The most common are forced-guided devices, mechanically linked relays,
or interface modules. The mechanical linkage between the contacts allows the device to be monitored by the External
Device Monitoring circuit for certain failures.
Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD
outputs of the EZ-SCREEN LS. FSDs can also be used to control an additional number of hazards by creating multiple
safety stop circuits.
Protective Stop (Safety Stop) Circuits
A protective stop (safety stop) allows for an orderly cessation of motion for safeguarding purposes, which results in a stop
of motion and removal of power from the MPCEs (assuming this does not create additional hazards). A protective stop
circuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically linked relays, which
are monitored through External Device Monitoring to detect certain failures in order to prevent the loss of the safety
function. Such a circuit can be described as a "safe switching point". Typically, protective stop circuits are either singlechannel, which is a series connection of at least two normally open contacts; or dual-channel, which is a separate
connection of two normally open contacts. In either method, the safety function relies on the use of redundant contacts to
control a single hazard. If one contact fails On, the second contact arrests the hazards and prevents the next cycle from
occurring.
The interfacing of the protective stop circuits must be accomplished so that the safety function cannot be suspended,
overridden, or defeated, unless accomplished in a manner of the same or greater degree of safety as the machine’s safety
related control system that includes the EZ-SCREEN LS.
The normally open safety outputs from an interface module provide a series connection of redundant contacts that form
protective stop circuits for use in either single-channel or dual-channel control.
Dual-Channel Control
Dual-channel control provides the ability to electrically extend the safe switching point beyond the FSD contacts. With
proper monitoring, this method of interfacing is capable of detecting certain failures in the control wiring between the
safety stop circuit and the MPCEs. These failures include a short-circuit of one channel to a secondary source of energy or
voltage, or a loss of the switching ability of one of the FSD outputs. Such failures may lead to a loss of redundancy, or to a
complete loss of safety, if not detected and corrected.
The possibility of a failure to the wiring increases as the physical distance between the FSD safety stop circuits and the
MPCEs increases, as the length or the routing of the interconnecting wires increases, or if the FSD safety stop circuits and
the MPCEs are located in different enclosures. For this reason, dual-channel control with EDM monitoring should be used in
any installation where the FSDs are located remotely from the MPCEs.
Single-Channel Control
Single-channel control uses a series connection of FSD contacts to form a safe switching point. After this point in the
machine’s safety-related control system, failures can occur that would result in a loss of the safety function (such as a
short-circuit to a secondary source of energy or voltage). For this reason, single-channel control interfacing should be used
only in installations where FSD safety stop circuits and the MPCEs are mounted within the same control panel, adjacent to
each other, and are directly connected to each other; or where the possibility of such a failure can be excluded. If this
cannot be achieved, then dual-channel control should be used.
Methods to exclude the possibility of these failures include, but are not limited to:
• Physically separating interconnecting control wires from each other and from secondary sources of power
• Routing interconnecting control wires in separate conduit, runs, or channels
• Locating all elements (modules, switches, and devices under control) within one control panel, adjacent to each
other, and directly connected with short wires
• Properly installing multi-conductor cabling and multiple wires through strain relief fittings. Over-tightening of a
strain-relief can cause short-circuits at that point.
• Using positive-opening or direct-drive components, installed and mounted in a positive mode

EZ-SCREEN® LS Safety Light Screen
4.4.3 Machine Primary Control Elements and EDM Input
A machine primary control element (MPCE) is an electrically powered element that directly controls the normal operation of
a machine in such a way that it is the last element (in time) to function when machine operation is to be initiated or
arrested (per IEC 61496-1). Examples include motor contactors, clutch/brakes, valves, and solenoids.
Depending on the level of risk of harm, it may be required to provide redundant MPCEs or other control devices that are
capable of immediately stopping the dangerous machine motion, irrespective of the state of the other. These two machine
control channels need not be identical (diverse redundant), but the stop time performance of the machine (Ts, used to
calculate the safety distance, see Calculating the Safety Distance (Minimum Distance) on page 13) must take into account
the slower of the two channels. Consult the machine manufacturer for additional information.
To ensure that an accumulation of failures does not compromise the redundant control scheme (cause a failure to danger),
a method to verify the normal functioning of MPCEs or other control devices is required. EZ-SCREEN LS provides a
convenient method for this verification: external device monitoring (EDM).
For the EZ-SCREEN LS external device monitoring to function properly, each device must include a normally closed,
forced-guided (mechanically linked) contact that can accurately reflect the status of the device. This ensures that the
normally open contacts, used for controlling hazardous motion, have a positive relationship with the normally closed
monitoring contacts and can detect a failure to danger (for example, contacts that are welded closed or stuck On).
It is strongly recommended that a normally closed, forced-guided monitoring contact of each FSD and MPCE be connected
in series with the EDM input (see Generic Wiring Diagram—8-pin Receiver and IM-T-9A Interface Module on page 43 ). If
this is done, proper operation will be verified. Monitoring FSD and MPCE contacts is one method of maintaining control
reliability (OSHA/ANSI) and Category 3 and 4 (ISO 13849-1).
If monitoring contacts are not available or do not meet the design requirement of being forced-guided (mechanically
linked), it is recommended you:
• Replace the devices so that they are capable of being monitored; or
• Incorporate the EDM function into the circuit as close to the MPCE as possible (for example, monitor the FSDs);
and
• Employ the use of well-tried, tested, and robust components, and generally accepted safety principles, including
fault exclusion, into the design and installation to either eliminate, or reduce to an acceptable (minimal) level of
risk, the possibility of undetected faults or failures that can result in the loss of the safety function.
The principle of fault exclusion allows the designer to design out the possibility of various failures and justify it through the
risk assessment process to meet the required level of safety performance, such as the requirements of Category 2, 3, or 4.
See ISO 13849-1/-2 for further information.
WARNING: EDM Monitoring
If the System is configured for “No Monitoring,” it is the user’s responsibility to ensure that
this does not create a hazardous situation.
4.4.4 External Device Monitoring
EZ-SCREEN LS provides two possible EDM configurations: 1-channel monitoring and no monitoring. Their functions are
described below. The most common form of EDM is 1-channel monitoring; its primary advantages is the simplicity of
wiring. The installation must prevent short circuits across the N.C. monitoring contacts and to secondary sources of power.

Figure 28. One-channel EDM status, with respect to safety output
External Device Monitoring Hookup
If not connected previously, it is again strongly recommended that one normally closed, forced-guided monitoring contact
of each FSD and MPCE be wired as shown in the monitoring circuit (see Generic Wiring Diagram—8-pin Receiver and IMT-9A Interface Module on page 43). Pin 3 of the receiver connector provides connection for the external device
monitoring input.
External device monitoring (EDM) must be wired in one of two configurations described below.
www.bannerengineering.com - Tel: 763.544.3164
37
EZ-SCREEN® LS Safety Light Screen
One-Channel Monitoring: This is a series connection of normally closed monitor contacts that are force-guided
(mechanically linked) from each device controlled by the EZ-SCREEN LS. The monitor contacts must be closed before the
EZ-SCREEN LS OSSDs can turn On. After the safety outputs (OSSDs) turn On, the status of the monitor contacts are no
longer monitored and may change state. However, the monitor contacts must be closed within 250 milliseconds of the
OSSD outputs going from On to Off.
Refer to Generic Wiring Diagram—8-pin Receiver and IM-T-9A Interface Module on page 43 for wiring. Connect the
monitor contacts between +24 V dc and EDM (pin 3).
No Monitoring: Use this configuration to perform the initial checkout; see Initial Checkout Procedure on page 28. If the
application does not require the EDM function, it is the user's responsibility to ensure that this configuration does not
create a hazardous situation.
To configure the EZ-SCREEN LS for no monitoring, connect EDM (Pin 3) to +24 V dc.
WARNING: Retrofit of 2-channel EDM Installations.
In existing installations using 2-channel external device monitoring (default setting of EZ-SCREEN and
EZ-SCREEN LP systems), the parallel wiring of the N.C. monitoring contacts must be rewired for
the series connection used for 1-channel EDM. If the required wiring changes are not made, the
device connected to pin 2 (Orn/Blk) will not be monitored and could result in undetected faults and
create an unsafe condition, which could result in serious bodily injury or death.
If there are any questions concerning retrofit installations, contact Banner Engineering.
4.4.5 Fault Output
The current sourcing (PNP) solid-state output (100 mA maximum) is used for control functions that are not safety related;
a typical use is to signal a lockout (fault) to a programmable logic controller (PLC). Available on both the receiver and
emitter, the output provides a fault signal (lockout = On). Interrupting (blocking) the sensing field is not considered a
lockout, so the Fault Output does not change state.
This feature is available only with 8-conductor models.
4.4.6 Scan Code Select
The 8-pin emitter and receiver may be configured to one of two Scan Codes (1 or 2). A receiver recognizes light only from
an emitter with the same scan code.
• Select Scan Code 1 by connecting pin 8 (violet wire) to 0 V dc or leaving it open (not connected). Prevent unused
wires from shorting to ground or to other sources of energy (for example, terminate with wire-nut).
• Select Scan Code 2 by connecting pin 8 (violet wire) to +24 V dc.
Both the emitter and its corresponding receiver must have the same setting. Standard 5-pin emitter or receiver models are
always configured for Scan Code 1.
4.4.7 Preparing for System Operation
After the initial trip test has been accomplished, and the OSSD safety outputs and EDM connections have been made to
the machine to be controlled, the EZ-SCREEN LS is ready for testing in combination with the guarded machine.
The operation of the EZ-SCREEN LS with the guarded machine must be verified before the combined System and machine
may be put into service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure described in
Commissioning Checkout on page 63.
4.4.8 Sensor Interchangeability
The figures and table below illustrate a wiring option that provides sensor interchangeability (or swapability)—the ability to
install either sensor at either QD connection.
The resulting installation provides the ability to swap the emitter and receiver position. This wiring option provides
advantages during installation, wiring, and troubleshooting.
To use this option, connect all emitter wires in parallel (color-for-color) to the receiver cable via individual wires or the
CSB.. splitter cordset (can be used with only emitters and receivers with similar connectors, such as a pair with 8-pin quick
disconnects or a pair with 5-pin quick disconnects.).
Model CSB.. splitter cordsets and DEE2R.. double-ended cordsets allow easy interconnection between an EZ-SCREEN LS
receiver and emitter, providing a single homerun cordset.

contacts of the Safety Device or Module. It is possible for suppressors to fail as a short circuit. If
installed directly across the output contacts, a short-circuited suppressor creates an unsafe
condition which may result in serious injury or death.

EZ-SCREEN® LS Safety Light Screen
5 Cascadeable EZ-SCREEN LS
5.1 Overview of Cascading
EZ-SCREEN LS emitters and receivers are available in cascadeable models. These models can be used as stand-alone light
screens, or can be cascaded up to four pairs in one system; see Figure 37 on page 44. The cascaded sensor pairs can be
any length, any number of beams, or have different resolutions (14 mm, 23 mm, and 40 mm), as long as each emitter
matches its receiver.
NOTE: EZ-SCREEN SLL.. (stand-alone) or SLLC.. (cascadeable) models can be used as the end sensor
pair. Other EZ-SCREEN components cannot be interfaced with the cascade input.
The control reliability, installation and alignment, electrical interface to the guarded machine, initial checkout, periodic
checkout, troubleshooting and maintenance features of cascadeable models are functionally identical to those of the
standard models.
Electrical connections are made via removable disconnect (RD) cordsets; see Cordsets on page 77. All receivers in a
cascade activate the same set of OSSD outputs: the OSSDs of the master receiver.
NOTE: In a cascaded system, all receivers are connected together, and all emitters are connected
together. Cascaded sensors are configured automatically.
WARNING: Scan Code
In situations where multiple systems are mounted closely together, or where a secondary emitter is in
view (within ±5°) and within range of an adjacent receiver, the adjacent systems must be configured
for different Scan Codes (one system set for Scan Code 1 and the other for Scan Code 2). If not, a
receiver may synchronize to the signal from the wrong emitter, reducing the safety function of the light
screen. This situation is discovered by performing the trip test.

5.1.1 System Components and Specifications
A multiple-light screen cascaded EZ-SCREEN LS system includes compatible emitter/receiver pairs (up to four), a
terminator plug (shipped installed on each cascade receiver) for the last receiver in the cascade, two RD cables or pigtail
cables to interface with the machine and provide power to the system, and pairs of double-ended (sensor interface) cables
to interconnect the emitters and the receivers in the cascade. (A “dummy” plug is installed at the cascade end of each
emitter. It is not required for operation, but maintains the emitter’s IP67 rating.) Additional cordsets may be used to
enable quick disconnect (QD) connections; see Cordsets on page 77.
The terminator plug (model EZLSA-RTP-1) must be used on the receiver in a stand-alone system, and on the last receiver
in a multiple-pair cascade, unless an EZA-RBK-1 key switch for remote teach fixed blanking, an RDLS-8..D cordset
interfaced with an E-stop or other hard contacts is in place (see Emergency Stop Buttons in Cascaded Systems on page
48, Interlock Switches in Cascaded Systems on page 50), or an EZLSA-K30LGR EZ-LIGHT or DELSEF-xxE cordset with a
remotely located EZ-LIGHT or indicator.
NOTE: The machine interface cable must connect to the sensor end adjacent to the status indicators.
Available single-ended, double-ended, and splitter cordsets are listed in Cordsets on page 77. Cordset lengths are limited
– for both the machine interface/power cables and the sensor interconnect cables; see Determining Interconnect Cordset
Lengths on page 45 for more information.

5.2 Determining Interconnect Cordset Lengths
The following cordset length charts are possible combinations for each side of example cascaded systems. Model
DELS-11...E cordsets are used for calculations. Other lengths and combinations are possible; call Banner Engineering for
assistance.
Figure 39. Cascade Cordset Connection
As the machine interface cordset lengthens, the voltage available at the first (master) sensor pair decreases, which results
in shorter possible interconnect cordsets to maintain supply voltage requirements at last cascaded sensor.

NOTE: The length of Emitter machine interface cordsets can be two times longer than those listed for
the receiver in the table above if a CSB Splitter cordset is not used. If a CSB Splitter cordset is used,
connect one branch of the CSB splitter to the receiver and other branch to the emitter via DEE2R
double-ended cordset up to the same length listed in the table above.
Of the standard DELS-11..E interconnect cordsets, all cascade installations (2, 3, or 4 pairs) can use up to a 15.3 m
(50.2 ft) DELS-1150E cordset to connect the sensor pairs (L2, L3, and L4), except for the following situations (refer
to the following table).
Because of the large number of possible combinations, the table for four cascaded light screens cordset options includes
only applications in which L2 = L4. A common installation is one that protects two areas of a machine, for example, the
front and back of a power press, and uses four EZ-SCREEN LS pairs to create two L-shaped sensing fields.

5.3 Response Time for Cascaded Light Screens
Response time is an important factor in determining a light screen’s safety distance (minimum distance). For cascaded EZSCREEN LS systems, that response time is dependent on the number of light screens, the number of beams in the light
screens, and their positions in the cascade. It can be calculated easily, in two ways:
• Based on the worst-case time for the entire cascade (where all light screens in the cascade have the same safety
distance)
• Individually for each light screen in the cascade (safety distance is calculated for each light screen in the cascade)
WARNING: Improper Installation
Failure to follow the installation guidelines and procedures may result in the ineffective or non-operation
of the Banner device that could create an unsafe condition resulting in serious injury or death.
5.3.1 Determining System Response Time
If the safety distance does not need to be optimized (at a minimum), simply add 6 ms to the response time of the receiver
with the longest response time Tr(max) (greatest number of beams), and use that number as the overall cascade system
response time.
Ds = K(Ts + Tr) + Dpf
where
Tr = Tr(max) + 6 ms
The 6 ms adder increases safety distance (Ds) a total of 10 mm (0.4 in) when using 1600 mm/s for the hand speed
constant K (see Calculating the Safety Distance (Minimum Distance) on page 13).

47
EZ-SCREEN® LS Safety Light Screen
5.3.2 Individual Response Time and Safety (Minimum) Distance
When calculating individual safety distance for each emitter/receiver pair, the pair’s position in the cascade affects its
response time, which then affects its safety distance (see safety distance formulas in Calculating the Safety Distance
(Minimum Distance) on page 13). The individual method results in an optimized safety distance for each light screen in the
cascade, while ensuring that each sensor pair is located at an adequate distance from the hazard.
The response time depends on how far the light screen is from the machine control. Each light screen position in the
cascade, starting from the first light screen in the cascade that is connected to the machine control, increases the light
screen’s response time by 2 ms. To calculate response time (Tr) for individual placement of each emitter/receiver pair in
the cascaded system, use the following formulas:
Position #1: Tr(cascade1) = Tr
Position #2: Tr(cascade2) = Tr + 2 ms
Position #3: Tr(cascade3) = Tr + 4 ms
Position #4: Tr(cascade4) = Tr + 6 ms
5.3.3 CSSI Response Time
When contacts (such as an E-stop button) are connected to the
CSSI cascaded receiver input, the CSSI response time is 40 ms
plus 2 ms for each additional light screen (slave pairs).
Emitters
This is an example of a four sensor pair, cascade system with the
individual response times calculated for each of the sensor pairs.
Light screens of other lengths/resolutions will have different
response times.

position #1 (connected directly to the machine control), maintains
its 11.6 ms response time. Response time for the second pair in
the cascade circuit increases by 2 ms, to 13.6 ms; for the third pair
by 4 ms, to 15.6 ms, and for the fourth pair by 6 ms, to 17.6 ms.

5.4 Emergency Stop Buttons in Cascaded Systems
Cascadeable EZ-SCREEN LS receivers may be connected to one or more E-stop buttons. The button(s) must connect to the
end of the last receiver in the cascade, in place of the terminator plug. The connected E-stop button(s) will activate/
deactivate the OSSD outputs in all receivers in the cascade.
48
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
The number of E-stop buttons allowed in a series connection is limited by the total resistance per channel. The total
resistance is the sum of all contact resistance values in the channel, plus the total wire resistance in the channel. The
maximum total resistance per channel is 100 Ω.
The CSSI input is a two-channel (4-wire) input such that the redundant channels must be in the same state (either open
or closed). The CSSI input can be connected to hard/relay contacts per requirements. The simultaneity between the two
. If
contacts, on opening and closing, is 3 seconds. If simultaneity is not met, the last receiver’s display will flash
simultaneity is not met, to clear the fault condition, close both inputs (rearm E-stop button), wait 3 seconds, and open
both channels within 3 seconds, then both contacts can be closed again.
WARNING: Emergency Stop Functions
Do not mute or bypass any Emergency Stop device. ANSI B11.19, ANSI NFPA79 and IEC/EN
60204-1 require that the Emergency Stop function remain active at all times.
5.4.1 E-Stop Switch Requirements (Positive-Opening)
As shown in Figure 41 on page 50, the E-stop switch must provide two contact pairs, which are closed when the switch is
in the armed position. Once activated, the E-stop switch must open its contacts and return to the closed-contact position
only after deliberate action (such as twisting, pulling, or unlocking). The switch should be a positive-opening type, as
described by IEC947-5-1. A mechanical force applied to such a button (or switch) is transmitted directly to the contacts,
forcing them open. This ensures that the switch contacts will open whenever the switch is activated. ANSI/NFPA 79
specifies the following additional requirements:
• Emergency Stop push buttons shall be located at each operator control station and at other operating stations
where emergency shutdown shall be required
• Stop and Emergency Stop push buttons shall be continuously operable from all control and operating stations
where located
• Actuators of Emergency Stop devices shall be colored Red. The background immediately around the device
actuator shall be colored Yellow. The actuator of a push-button-operated device shall be of the palm or mushroomhead type
• The Emergency Stop actuator shall be a self-latching type
NOTE: Some applications may have additional requirements. The user must comply with all relevant
regulations.
WARNING: Multiple Emergency Stop Switches
When two or more E-stop switches are connected to the same EZ-SCREEN LS receiver, the contacts of
the E-stop switches must be connected together in series. This series combination is then wired to the
respective EZ-SCREEN LS receiver input.
Do not connect the contacts of multiple E-stop switches in parallel to the EZ-SCREEN LS inputs; this
defeats the switch contact monitoring ability of the EZ-SCREEN LS light curtain, and creates an unsafe
condition which could result in serious bodily injury or death.
In addition, when two or more E-stop switches are used, each switch must be individually actuated
(engaged), then re-armed and reset the machine's safety-related control system. This allows the
monitoring circuits to check each switch and its wiring to detect faults. Failure to test each switch
individually in this manner could result in undetected faults and create an unsafe condition which could
result in serious bodily injury or death.
WARNING: Reset Routine Required
U.S. and international standards require that a reset routine be performed after clearing the cause of a
stop condition (for example, arming an E-stop button, closing an interlocked guard, etc.). Allowing the
machine to restart without actuating the normal start command/device can create an unsafe
condition which may result in serious injury or death.

5.5 Interlock Switches in Cascaded Systems
The Cascade input may be used to monitor interlock safety gates or guards. Requirements vary widely for the level of
control reliability or safety category (per ISO 13849-1) in the application of interlocked guards. While Banner Engineering
recommends the highest level of safety in any application, the user is responsible to safely install, operate, and maintain
each safety system, and comply with all relevant laws and regulations. Of the following applications, Figure 42 on page
52 meets or exceeds the requirements for OSHA/ANSI control reliability and Safety Category 4, per ISO 13849-1.
The CSSI input is a two-channel (4-wire) input such that the redundant channels must be in the same state (either open
or closed). The CSSI input can be connected to hard/relay contacts per requirements. The simultaneity between the two
. If
contacts, on opening and closing, is 3 seconds. If simultaneity is not met, the last receiver’s display will flash
simultaneity is not met, to clear the fault condition, close both inputs (rearm E-stop button), wait 3 seconds, and open
both channels within 3 seconds, then both contacts can be closed again.
WARNING: Safety Distances and Safe Openings
It must not be possible for personnel to reach any hazard through an opened guard or by reaching
over, under, around, or through any opening in the guard before the hazardous situation has ceased.
See ANSI B11.19 or ISO 14119, ISO 14120 and ISO 13857 for information on determining safety
distances and safe opening sizes for your guarding device.
5.5.1 Interlock Guarding Requirements
The following general requirements and considerations apply to the installation of interlocked gates and guards for the
purpose of safeguarding. Refer to the relevant regulations to be sure to comply with all necessary requirements.
50
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
Hazards guarded by the interlocked guard must be prevented from operating until the guard is closed. A Stop command
must be issued to the guarded machine if the guard opens while the hazard is present. Closing the guard must not, by
itself, initiate hazardous motion; a separate procedure must be required to initiate the motion. The safety switches must
not be used as a mechanical or end-of-travel stop.
The guard must be located at an adequate distance from the danger zone (so the hazard has time to stop before the guard
is opened sufficiently to provide access to the hazard), and it must open either laterally or away from the hazard, not into
the safeguarded area. Depending on the application, an interlocked gate or door should not be able to close by itself and
activate the interlocking circuitry. In addition, the installation must prevent personnel from reaching over, under, around,
or through the guard to the hazard. Any openings in the guard must not allow access to the hazard (see ANSI B11.19 or
the appropriate standard). The guard must be strong enough and designed to protect personnel and contain hazards
within the guarded area, which may be ejected, dropped, or emitted by the machine.
The safety switches and actuators used with the cascaded system must be designed and installed so that they cannot be
easily defeated. They must be mounted securely, so that their physical position cannot shift, using reliable fasteners that
require a tool to remove. Mounting slots in the housings are for initial adjustment only; final mounting holes must be used
for permanent location.
5.5.2 Positive-Opening Interlocking Safety Switches
Two individually mounted safety interlock switches are recommended for each guard to meet Category 4, per ISO
13849-1, and must satisfy several requirements. Each switch must provide at minimum, one normally closed (N.C.)
electrically isolated contact to interface with the Cascade input (Figure 42 on page 52).
The contacts must be of positive-opening design, with one or more normally closed contacts rated for safety. Positiveopening operation causes the switch to be forced open, without the use of springs, when the switch actuator is disengaged
or moved from its home position. In addition, the switches must be mounted in a positive state to move/disengage the
actuator from its home position and open the normally closed contact when the guard opens.
Series-connected, positive-opening interlock switch circuits do not meet ISO 13849-1 Category 4 and may not meet
Control Reliability requirements because of the potential of an inappropriate reset or a potential loss of the safety stop
signal. A multiple connection of this type should not be used in applications where loss of the safety stop signal or an
inappropriate reset could lead to serious injury or death.
WARNING: Series Connection of Safety Switches
Monitoring multiple guards with a series connection of safety interlock switches may result in a failure
being masked or not detected at all. When such a configuration is used, periodic checks must be
performed regularly to verify proper operation. All failures must be immediately corrected (for example,
immediately replacing a failed switch), or the loss of the safety stop signal or an inappropriate reset
may lead to serious injury or death.

6.3 Normal Operation
6.3.1 System Power-Up
When power is applied, each sensor conducts self-tests to detect critical internal faults, determine configuration settings,
and prepare the EZ-SCREEN LS for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs
remain Off and diagnostic information displays on the sensor’s Diagnostic Display. If no faults are detected, the EZSCREEN LS automatically enters Alignment mode, and the receiver looks for an optical sync pattern from the emitter. If
the receiver is aligned and receives the proper sync pattern, it enters Run mode and begins scanning to determine the
blocked or clear status of each beam. No manual reset operation is required.
6.3.2 Run Mode
If any beams become blocked while the EZ-SCREEN LS is running, the receiver outputs turn Off within the stated EZSCREEN LS response time (see Specifications on page 65). If all the beams then become clear, the receiver outputs
come back On. No resets are needed. All required machine control resets are provided by the machine control circuit.
Internal Faults (Lockouts): If either sensor detects a critical fault, scanning ceases, the receiver outputs turn Off and
diagnostic information displays on the sensor’s Diagnostic Display. See Lockout Conditions on page 58 for resolution of
error/fault conditions.
6.4 Periodic Checkout Requirements
To ensure continued reliable operation, the System must be checked out periodically.
At every shift change, power-up, and machine setup change, the Daily Checkout should be performed; this checkout
may be performed by a Designated or Qualified Person.
Semi-annually, the System and its interface to the guarded machine should be thoroughly checked out; this checkout
must be performed by a Qualified Person (see Checkout Procedures on page 63). A copy of these test results should be
posted on or near the machine.
Whenever changes are made to the System (either a new configuration of the EZ-SCREEN LS System or changes to
the machine), the Commissioning Checkout should be performed (see Commissioning Checkout on page 63).

NOTE: Verify Proper Operation
The EZ-SCREEN LS can operate as it is designed only if it and the guarded machine are operating
properly, both separately and together. It is the user’s responsibility to verify this, on a regular basis,
as instructed in Checkout Procedures on page 63. Failure to correct such problems can result in an
increased risk of harm.
Before the System is put back into service, verify that the EZ-SCREEN LS System and the guarded
machine perform exactly as outlined in the checkout procedures and any problem(s) are found and
corrected.

7 Troubleshooting and Maintenance
7.1 Lockout Conditions
A Lockout condition causes all of the EZ-SCREEN LS OSSD outputs to turn or remain Off, sending a stop signal to the
guarded machine. Each sensor provides diagnostic error codes to assist in the identification of the cause(s) of lockouts
(see Receiver Error Codes and Emitter Error Codes) ).
The following tables indicate a sensor lockout condition:

7.2 Recovery Procedures
To recover from a Lockout condition, correct all errors, power the sensor down, wait a few seconds, and then power the
sensor back up.
WARNING: Lockouts and Power Failures
Power failures and Lockout conditions are indication of a problem and must be investigated immediately
by a Qualified Person12. Attempts to continue to operate machinery by bypassing the Banner
device or other safeguards is dangerous and may result in serious bodily injury or death.
WARNING: Shut Down Machinery Before Servicing
The machinery to which the Banner device is connected must not be operating at any time during
major service or maintenance. This may require lockout/tagout procedures (refer to OSHA1910.147,
ANSI Z244-1, ISO 14118 or the appropriate standard for controlling hazardous energy). Servicing the
Banner device while the hazardous machinery is operational may result in serious bodily
injury or death.

EZ-SCREEN® LS Safety Light Screen
7.3 Electrical and Optical Noise
The EZ-SCREEN LS is designed and manufactured to be highly resistant to electrical and optical noise and to operate
reliably in industrial settings. However, serious electrical and/or optical noise may cause a random Trip. In very extreme
electrical noise cases, a Lockout is possible. To minimize the effects of transitory noise, the EZ-SCREEN LS responds to
noise only if the noise is detected on multiple consecutive scans.
If random nuisance Trips occur, check the following:
•
•
•
Poor connection between the sensor and earth ground
Optical interference from adjacent light screens or other photoelectrics
Sensor input or output wires routed too close to noisy wiring
7.3.1 Sources of Electrical Noise
Checking for sources of electrical noise: It is very important that the light screen sensors have a good earth ground.
Without this, the System can act like an antenna and random Trips and Lockouts can occur.
All EZ-SCREEN LS wiring is low voltage; running these wires alongside power wires, motor/servo wires, or other highvoltage wiring, can inject noise into the EZ-SCREEN LS System. It is good wiring practice (and may be required by code)
to isolate EZ-SCREEN LS wires from high-voltage wires.
The Banner model BT-1 Beam Tracker (see Alignment Aids on page 87 ) is a good tool for detecting electrical noise. It
can be used to detect electrical transient spikes and surges. Cover the lens of the BT-1 with electrical tape to block optical
light from entering the receiver lens. Press the RCV button on the BT-1 and position the Beam Tracker on the wires going
to the EZ-SCREEN LS or any other nearby wires. The noise caused by switching of the inductive loads should be addressed
by installing proper transient suppression across the load.
7.3.2 Sources of Optical Noise
Checking for sources of optical noise: Turn off the emitter or completely block the emitter, then use a Banner BT-1
Beam Tracker (see Alignment Aids on page 87 ) to check for light at the receiver. Press the RCV button on the BT-1 and
move it across the full length of the receiver’s sensing window. If the BT-1’s indicator lights, check for emitted light from
other sources (other safety light screens, grids or points, or standard photoelectric sensors).
7.4 Cleaning
EZ-SCREEN LS emitters and receivers are constructed of aluminum with a yellow painted finish and are rated IP67. Lens
covers are acrylic. Emitters and receivers are best cleaned using mild detergent or window cleaner and a soft cloth. Avoid
cleaners containing alcohol, as they may damage the acrylic lens covers.
7.5 Warranty Service
Contact Banner Engineering for troubleshooting of this device. Do not attempt any repairs to this Banner device; it
contains no field-replaceable parts or components. If the device, device part, or device component is determined to
be defective by a Banner Applications Engineer, they will advise you of Banner's RMA (Return Merchandise Authorization)
procedure.
Important: If instructed to return the device, pack it with care. Damage that occurs in return shipping
is not covered by warranty.
7.6 Manufacturing Date
Every EZ-SCREEN LS produced is marked with a code that defines the week and year of manufacture and manufacturing
location. The code format (U.S. Standard format) is: YYWWL
• YY = year of manufacture, 2 digits

WARNING: Do Not Use Machine Until System Is Working Properly
If all of these checks cannot be verified, do not attempt to use the safety system that includes
the Banner device and the guarded machine until the defect or problem has been corrected. Attempts
to use the guarded machine under such conditions may result in serious bodily injury or
death.
Perform this checkout procedure as part of the System installation after the System has been interfaced to the guarded
machine, or whenever changes are made to the System (either a new configuration of the EZ-SCREEN LS or changes to
the machine). A Qualified Person must perform the procedure. Checkout results should be recorded and kept on or near
the guarded machine as required by applicable standards.
To prepare the System for this checkout:
1. Examine the guarded machine to verify that it is of a type and design compatible with the EZ-SCREEN LS System.
See Examples: Inappropriate Applications on page 8 for a list of misapplications.
2. Verify that the EZ-SCREEN LS is configured for the intended application.
3. Verify that the safety distance (minimum distance) from the closest danger point of the guarded machine to the
defined area is not less than the calculated distance, per Calculating the Safety Distance (Minimum Distance) on
page 13.
4. Verify that:
• Access to any dangerous parts of the guarded machine is not possible from any direction not protected by
the EZ-SCREEN LS System, hard (fixed) guarding, or supplemental safeguarding, and
• It is not possible for a person to stand between the defined area and the dangerous parts of the machine,
or
www.bannerengineering.com - Tel: 763.544.3164
63
EZ-SCREEN® LS Safety Light Screen
•
Supplemental safeguarding and hard (fixed) guarding, as described by the appropriate safety standards,
are in place and functioning properly in any space (between the defined area and any hazard) which is
large enough to allow a person to stand undetected by the EZ-SCREEN LS.
5. If used, verify that all reset switches are mounted outside and in full view of the guarded area, out of reach of
anyone inside the guarded area, and that means of preventing inadvertent use is in place.
6. Examine the electrical wiring connections between the EZ-SCREEN LS OSSD outputs and the guarded machine’s
control elements to verify that the wiring meets the requirements stated in Electrical Connections to the Guarded
Machine on page 35.
7. Inspect the area near the defined area (including work pieces and the guarded machine) for reflective surfaces (see
Adjacent Reflective Surfaces on page 17). Remove the reflective surfaces if possible by relocating them, painting,
masking or roughening them. Remaining problem reflections will become apparent during the Trip Test.
8. Verify that power to the guarded machine is Off. Remove all obstructions from the defined area. Apply power to the
EZ-SCREEN LS System.
9. Observe the Status indicators and Diagnostic Display:
• Lockout: Status flashing red; all others Off
• Blocked: Status—Solid red; one or more Alignment indicators— Solid red; Run Mode— Solid amber
• Clear: Status—Solid green; Alignment indicators— Solid green (flashing green indicates blanking is
enabled); Run Mode— Solid amber
10. A Blocked condition indicates that one or more of the beams is misaligned or interrupted. See the Alignment
procedure in to correct this situation.
11. After the green and amber Status indicators are On, perform the trip test (Trip Test on page 34) on each sensing
field to verify proper System operation and to detect possible optical short circuits or reflection problems. Do not
continue until the EZ-SCREEN LS passes the trip test.
Important: Do not expose any individual to any hazard during the following checks.
WARNING: Before Applying Power to the Machine
Verify that the guarded area is clear of personnel and unwanted materials (such as tools) before
applying power to the guarded machine. Failure to do so may result in serious bodily injury or
death.
12. Apply power to the guarded machine and verify that the machine does not start up.
13. Interrupt (block) the defined area with the supplied test piece and verify that it is not possible for the guarded
machine to be put into motion while the beam(s) is blocked.
14. Initiate machine motion of the guarded machine and, while it is moving, use the supplied test piece to block the
defined area. Do not attempt to insert the test piece into the dangerous parts of the machine. Upon blocking any
beam, the dangerous parts of the machine must come to a stop with no apparent delay.
15. Remove the test piece from the beam; verify that the machine does not automatically restart, and that the
initiation devices must be engaged to restart the machine.
16. Remove electrical power to the EZ-SCREEN LS. Both OSSD outputs should immediately turn Off, and the machine
must not be capable of starting until power is re-applied to the EZ-SCREEN LS.
17. Test the machine stopping response time, using an instrument designed for that purpose, to verify that it is the
same or less than the overall system response time specified by the machine manufacturer. A Banner Applications
Engineer can recommend a suitable instrument.
Do not continue operation until the entire checkout procedure is complete and all problems are
corrected.

EZ-SCREEN® LS Safety Light Screen
10 Components
10.1 Models
An EZ-SCREEN LS “System” refers to a compatible emitter and receiver of equal length and resolution (available in pairs or
separately), including cascaded sensors, and their cordsets. Mounting hardware is included with each emitter and receiver.
Special-purpose mounting brackets both for standalone pairs and for cascades are also available. Depending on the
connection option, interfacing solutions include IM-T-.. modules, redundant positively guided contactors, safety modules/
controllers, and muting modules.
The 13 mm (0.5 in) minimum bend radius for all cordset models accommodates low-clearance installations; cords can exit
to the left, right, or back of the sensor, when mounting. The pigtail QD option is useful for connection to splitter cables or
other QD cordsets.

To determine the components required for an EZ-SCREEN LS system using the Model Key:
1. Determine if the application calls for a stand-alone (a single, non-cascade emitter and receiver pair) or if a cascade
pair is to be used as a stand-alone and/or with multiple pairs to be ordered are part of a cascaded system.
2. Choose an Emitter (E), a Receiver (R), or a Pair (P).
3. Choose resolution (14, 23, or 40 mm) and defined area.
4. Determine the Machine Interface connection style: 300 mm pigtail QD (5-pin or 8-pin) or a Removable Disconnect
(RD).
5. Model number(s) can be verified in the models tables.
6. See Cordsets on page 77 for mating cordsets:
• Models with RD connection use either RDLS-8..D, DELS-11..E, DELSE-81D, or DELSE-51D
• Models with P8 (P88) suffix use QDE-8..D, DEE2R-8..D, or CSB-M128..M1281
• Models with P5 (P55) suffix use QDE-5..D, DEE2R-5..D, or CSB-M125..M1251 (MQDEC-406SS is used in
applications where pin 5 is open and ground is via mounting brackets)
7. See Accessories on page 77 for interfacing solutions and accessories.
10.1.1 Ordering Guide
To order an EZ-SCREEN LS system, see Figure 46 on page 71:
1. Determine if the application calls for a stand-alone (single, non-cascade emitter and receiver pair) or if a cascade
pair is to be used as a stand-alone and/or with multiple pairs to be ordered are part of a cascaded system.
2. Determine the connection style, which is typically dictated by the type of interfacing with the machine's safetyrelated control system (300 mm pigtail QD (5-pin or 8-pin) or a Removable Disconnect).
3. Chose the model number(s) from the applicable model number table. Model numbers listed in the tables are RD
connection style model numbers. Add a P5 (or P55) or a P8 (or P88) at the end of the listed model number for a
sensor with a 300 mm (1 ft) pigtail M12/Euro-style QD.

10.2 Accessories
10.2.1 Cordsets
Machine interface cordsets provide power to the first emitter/receiver pair. Sensor interconnect cables provide power to
subsequent emitters and receivers in the cascade. Cordsets typically have yellow PVC cables and black overmolds.
A removable disconnect (RD) is required to connect directly to the sensor housing. QD connectors are used for cable-tocable interconnections and connections to other devices.
Single-ended (to connect to the machine interface):
RDLS-8..D RD-to-flying leads is used with sensors without a 300 mm pigtail M12 QD
QDE-8..D QD-to-flying leads is used with sensors with a 8-pin 300 mm pigtail M12 QD (model ends in P8)
QDE-5..D QD-to-flying leads is used with sensors with a 5-pin 300 mm pigtail M12 QD (model ends in P5)
Double-ended
DELS-11..E RD-to-RD is used for sensor interconnect in a cascading system
DEE2R-8..D M12 QD-to-M12 QD (female-male) is used for extending the length of cordsets and directly connects to
other devices with a 8-pin M12 QD
DEE2R-5..D M12 QD-to-M12 QD (female-male) is used for extending the length of cordsets and directly connects to
other devices with a 5-pin M12 QD
MQDEC-4..SS M12 QD-to-M12 QD (female-male) is used for connecting to devices that do not have earth ground on
pin 5 of a 5-pin QD (In such situations, earth ground must be provided via the mounting brackets)
DELSE-81D RD-to M12 QD (male) is used to create or replace an 8-pin 300 mm pigtail M12 QD
DELSE-51D RD-to M12 QD (male) is used to create or replace a 5-pin 300 mm pigtail M12 QD
DELSEF-81D RD-to M12 QD (female) is used for remote teach fixed blanking programing
DELSEF-4..D RD-to M12 QD (female) is used for connecting two-color EZ-LIGHT or other indicators
Splitter cordsets
CSB-M128..M1281 allow easy interconnection between an 8-pin receiver and 8-pin emitter, and provides a single
trunk cable for the optional interchangeable ("swapable") hookup
CSB-M125..M1251 allow easy interconnection between a 5-pin receiver and 5-pin emitter, and provides a single trunk
cable for the optional interchangeable ("swapable") hookup
NOTE: See Routing Cordsets on page 27 and Determining Interconnect Cordset Lengths on page 45 for
maximum cordset lengths.

EZ-SCREEN® LS Safety Light Screen
12 Glossary
A
ANSI (American National Standards Institute)
Acronym for the American National Standards
Institute, an association of industry representatives
that develops technical standards (including safety
standards). These standards comprise a consensus
from a variety of industries on good practice and
design. ANSI standards relevant to application of
safety products include the ANSI B11 Series, and
ANSI/RIA R15.06. See Standards and Regulations on
page 93.
Auto Power-Up
A safety light screen system feature that enables the
system to be powered up into Run mode (or recover
from a power interruption) without requiring a
manual reset.
B
Blanking
A programmable feature of a safety light screen
system which allows the light screen to ignore
certain objects located within the defined area. See
Floating Blanking and Reduced Resolution.
Brake
A mechanism for stopping, slowing, or preventing
motion.
Blocked Condition
A condition that occurs when an opaque object of
sufficient size blocks/interrupts one or more light
screen beams. When a blocked condition occurs,
OSSD1 and OSSD2 outputs simultaneously turn off
within the system response time.
C
Cascade
Series connection (or "daisy-chaining") of multiple
emitters and receivers.
Control Reliability
A method of ensuring the performance integrity of a
control system or device. Control circuits are
designed and constructed so that a single failure or
fault within the system does not prevent the normal
stopping action from being applied to the machine
when required, or does not create unintended
machine action, but does prevent initiation of
successive machine action until the failure is
corrected.
CE
Abbreviation for "Conformité Européenne" (French
translation of "European Conformity"). The CE mark
on a product or machine establishes its compliance
with all relevant European Union (EU) Directives and
the associated safety standards.
Clutch
A mechanism that, when engaged, transmits torque
to impart motion from a driving member to a driven
member.
CSA
Abbreviation for Canadian Standards Association, a
testing agency similar to Underwriters Laboratories,
Inc. (UL) in the United States. A CSA-certified
product has been type-tested and approved by the
Canadian Standards Association as meeting electrical
and safety codes.
D
Defined Area
The "screen of light" generated by a safety light
screen system, defined by the height and the safety
distance (minimum distance) of the emitter and
receiver. When the defined area is interrupted by an
opaque object of a specified cross section, a Trip or
Latch condition results.
94
Designated Person
A person or persons identified and designated in
writing, by the employer, as being appropriately
trained and qualified to perform a specified checkout
procedure.
www.bannerengineering.com - Tel: 763.544.3164
EZ-SCREEN® LS Safety Light Screen
E
Emitter
The light-emitting component of a safety light screen
system, consisting of a row of synchronized
modulated LEDs. The emitter, together with the
receiver (placed opposite), creates a "screen of light"
called the defined area.
External Device Monitoring (EDM)
A means by which a safety device (such as a safety
light screen) actively monitors the state (or status)
of external devices that may be controlled by the
safety device. A lockout of the safety device will
result if an unsafe state is detected in the external
device. External device(s) may include, but are not
limited to: MPCEs, captive contact relays/contactors,
and safety modules.
F
Failure to Danger
A failure which delays or prevents a machine safety
system from arresting dangerous machine motion,
thereby increasing risk to personnel.
FMEA (Failure Mode and Effects Analysis)
A testing procedure by which potential failure modes
in a system are analyzed to determine their results
or effects on the system. Component failure modes
that produce either no effect or a Lockout condition
are permitted; failures which cause an unsafe
condition (a failure to danger) are not. Banner safety
products are extensively FMEA tested.
Final Switching Device (FSD)
The component of the machine’s safety-related
control system that interrupts the circuit to the
machine primary control element (MPCE) when the
output signal switching device (OSSD) goes to the
OFF-state.
G
Guarded Machine
The machine whose point of operation is guarded by
the safety system.
H
Hard (Fixed) Guard
Screens, bars, or other mechanical barriers affixed
to the frame of the machine intended to prevent
entry by personnel into the hazardous area(s) of a
machine, while allowing the point of operation to be
viewed. The maximum size of the openings is
determined by the applicable standard, such as
Table O-10 of OSHA 29CFR1910.217, also called a
"fixed barrier guard."
Hazard Point
The closest reachable point of the hazardous area.
Hazardous Area
An area that poses an immediate or impending
physical hazard.
Harm
Physical injury or damage to the health of people,
which may result through direct interaction with the
machine or through indirect means, as a result of
damage to property or to the environment.
I
Internal Lockout
A Lockout condition that is due to an internal safety
system problem. Generally, indicated by the red
Status indicator LED (only) flashing. Requires the
attention of a Qualified Person.
K
Key Reset (Manual Reset)
A key-operated switch used to reset a safety light
screen system to RUN mode following a Lockout
condition. Also refers to the act of using the switch.
www.bannerengineering.com - Tel: 763.544.3164
95
EZ-SCREEN® LS Safety Light Screen
L
Latch Condition
The response of the safety light screen safety
outputs (for example, OSSDs) when an object equal
to or greater than the diameter of the specified test
piece enters the defined area. In a Latch condition,
safety outputs simultaneously de-energize and open
their contacts. The contacts are held (latched) open
until the object is removed from the defined area
and a manual reset is performed. A latching output
is used most often in perimeter guarding
applications. (See Trip Condition.)
Lockout Condition
A safety light screen condition that is automatically
attained in response to certain failure signals (an
internal lockout). When a Lockout condition occurs,
the safety light screen’s safety outputs turn Off; the
failure must be corrected and a manual reset is
required to return the system to Run mode.
M
Machine Primary Control Element (MPCE)
An electrically powered element, external to the
safety system, which directly controls the machine’s
normal operating motion in such a way that the
element is last (in time) to operate when machine
motion is either initiated or arrested.
Minimum Object Sensitivity (MOS)
The minimum-diameter object that a safety light
screen system can reliably detect. Objects of this
diameter or greater will be detected anywhere in the
defined area. A smaller object can pass undetected
through the light if it passes exactly midway
between two adjacent light beams. Also known as
MODS (Minimum Object Detection Size). See also
Specified Test Piece.
Machine Response Time
The time between the activation of a machine
stopping device and the instant when the dangerous
parts of the machine reach a safe state by being
brought to rest.
Muting
The automatic suspension of the safeguarding
function of a safety device during a non-hazardous
portion of the machine cycle.
O
Off State
The state in which the output circuit is interrupted
and does not permit the flow of current.
OSHA (Occupational Safety and Health
Administration)
A U.S. Federal agency, Division of the U.S.
Department of Labor, that is responsible for the
regulation of workplace safety.
On State
The state in which the output circuit is complete and
permits the flow of current.
OSSD
Output Signal Switching Device. The safety outputs
that are used to initiate a stop signal.
P
Part-Revolution Clutch
A type of clutch that may be engaged or disengaged
during the machine cycle. Part-revolution clutched
machines use a clutch/brake mechanism, which can
arrest machine motion at any point in the stroke or
cycle.
Pass-Through Hazard
A pass-through hazard is associated with
applications where personnel may pass through a
safeguard (which issues a stop command to remove
the hazard), and then continues into the guarded
area, such as in perimeter guarding. Subsequently,
their presence is no longer detected, and the related
danger becomes the unexpected start or restart of
the machine while personnel are within the guarded
area.
96
Point of Operation
The location of a machine where material or a
workpiece is positioned and a machine function is
performed upon it.
PSDI (Presence-Sensing Device Initiation)
An application in which a presence-sensing device is
used to actually start the cycle of a machine. In a
typical situation, an operator manually positions a
part in the machine for the operation. When the
operator moves out of the danger area, the presence
sensing device starts the machine (no start switch is
used). The machine cycle runs to completion, and
the operator can then insert a new part and start
another cycle. The presence sensing device
continually guards the machine. Single-break mode
is used when the part is automatically ejected after
the machine operation. Double-break mode is used
when the part is both inserted (to begin the
operation) and removed (after the operation) by the
operator. PSDI is commonly confused with "Trip
Initiate." PSDI is defined in OSHA CFR1910.217.
Banner safety light screen systems may not be used
as PSDI devices on mechanical power presses, per
OSHA regulation 29 CFR 1910.217.

Qualified Person
A person who, by possession of a recognized degree
or certificate of professional training, or who, by
extensive knowledge, training and experience, has
successfully demonstrated the ability to solve
problems relating to the subject matter and work.
R
Receiver
The light-receiving component of a safety light
screen system, consisting of a row of synchronized
phototransistors. The receiver, together with the

The use of a manually operated switch to restore the
safety outputs to the On state from a lockout
condition.
S
Self-Checking (Circuitry)
A circuit with the capability to electronically verify
that all of its own critical circuit components, along
with their redundant backups, are operating
properly. Banner safety light screen systems and
safety modules are self-checking.
Specified Test Piece
An opaque object of sufficient size used to block a
light beam to test the operation of a safety light
screen system. When inserted into any part of the
defined area, it will place a system into a Trip or
Latch condition. Banner supplies specified test pieces
with each system. See also Minimum Object
Sensitivity.
Separation Distance (Safety Light Screen)
The minimum distance required to allow the
machine’s hazardous motion to stop completely,
before a hand (or other object) can reach the
nearest hazard point. Measured from the midpoint of
the defined area to the nearest hazard point. Factors
that influence minimum separation distance include
the machine stop time, the light screen system
response time, and the light screen minimum object
detection size.
Supplemental Guarding
Additional safeguarding device(s) or hard guarding,
used to prevent a person from reaching over, under,
through or around the primary safeguard or
otherwise accessing the guarded hazard.
T
Test Piece
An opaque object of sufficient size used to block a
light beam to test the operation of a safety light
screen system.
Trip Initiate
The resetting of a safeguard causing the initiation of
machine motion or operation. Trip Initiate is not
allowed as a means to initiate a machine cycle per
NFPA 79 and ISO 60204-1, and is commonly
confused with PSDI.
Trip Condition
The response of the safety outputs (for example,
OSSDs) of a safety light screen system when an
object equal to or greater than the diameter of the
specified test piece enters the defined area. In a Trip
condition, the OSSDs simultaneously de-energize. A
Trip condition clears (resets) automatically when the
object is removed from the defined area. (See Latch
Condition.)
U
UL (Underwriters Laboratory)
A third-party organization that tests products for
compliance with appropriate standards, electrical
codes, and safety codes. Compliance is indicated by
the UL listing mark on the product.
