and dependability
2.2 System Descripon
Note: This manual refers to an emier and its receiver, and their cabling as "a System".
Banner EZ-SCREEN Type 2 emiers and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelectronic
"curtain of light", or "light screen". EZ-SCREEN Type 2 typically is used for point-of-operaon safeguarding, and is suited to safeguard a
variety of lower-risk machinery.
The EZ-SCREEN Type 2 is a two-piece (two-box) system comprising an emier and a receiver, but no external controller. The external
device monitoring (EDM) funcon ensures the fault detecon capability required by EN ISO 13849-1 Category 2.
The EZ-SCREEN Type 2 emiers have a row of synchronized modulated infrared (invisible) light-eming diodes (LEDs) in a compact
metal housing. Receivers have a corresponding row of synchronized photodetectors. The light screen created by the emier and
receiver is called the dened area; its width and height are determined by the length of the sensor pair and the distance between them.
The maximum range is 15 m (50 ), which decreases if corner mirrors are used. Resoluon is 30 mm (1.18 in).
Both emier and receiver feature LEDs to provide connuous indicaon of the System’s operang status, alignment and error
condions.
In typical operaon, if any part of an operator’s body (or any opaque object) of more than a pre-determined cross secon 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
moon of the guarded machine.
Both OSSD outputs must be connected to the machine control so that the machine’s safety-related control system interrupts the circuit
or power to the MPCEs (Machine Primary Control Elements), resulng in a non-hazardous condion. Each OSSD is capable of sourcing
0.5A at +24V dc.
The OSSD safety outputs are not capable of performing a “handshake” communicaon with the Muteable Safety Stop Interface (MSSI)
or Universal Safety Stop Interface (USSI) found on other Banner Engineering safety products.
EZ-SCREEN Type 2 is extensively FMEA (Failure Mode and Eects Analysis) tested to IEC 61496-1/-2 requirements. The design of the EZ-
SCREEN Type 2 has considered all single faults such that a loss of a crical safety funcon will result in a stop command and a lockout
condion. In the event of an accumulaon of undetected faults, a remote external test (or check) is required to maintain the safety
funcon.

Electrical connecons are made through M12 (or Euro-style)
quick-disconnects. An oponal hookup that provides sensor
interchangeability (or “swapability”) – the ability to install either
sensor at either QD connecon – is possible. Using a parallel
connecon (color-for-color), the emier cable can be connected
to the receiver cable, providing the ability to swap the emier and
receiver posion, similar to a popular feature of Banner MINI-
SCREEN®safety light screens. This hookup opon provides
advantages during installaon, wiring, and troubleshoong.
All models require a supply voltage of +24V dc ±20%.

2.3 Appropriate Applicaons and Limitaons
WARNING: Read this Secon Carefully Before Installing the System
If all mounng, installaon, interfacing, and checkout procedures are not followed properly, the Banner device
cannot provide the protecon for which it was designed. The user has the responsibility to ensure that all local,
state, and naonal laws, rules, codes, or regulaons relang to the installaon and use of this control system in
any parcular applicaon are sased. Ensure that all legal requirements have been met and that all technical
installaon and maintenance instrucons 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 Qualied Persons1, in accordance with this manual and applicable safety regulaons.
The Banner EZ-SCREEN Type 2 Light Screen is intended for lower-risk machine guarding and other safeguarding applicaons, as
determined by a risk assessment. It is the user’s responsibility to verify whether the safeguarding is appropriate for the applicaon and
is installed, as instructed by this manual, by a Qualied Person.
The EZ-SCREEN Type 2 ability to perform its safeguarding funcon depends upon the appropriateness of the applicaon and upon its
proper mechanical and electrical installaon and interfacing to the guarded machine. If all mounng, installaon, interfacing, and
checkout procedures are not followed properly, the EZ-SCREEN Type 2 cannot provide the protecon for which it was designed.
CAUTION: Install System Only on Appropriate Applicaons
Banner EZ-SCREEN Type 2 is for use only on machinery that can be stopped immediately aer a stop signal is
issued at any point in the machine's stroke or cycle, such as part-revoluon clutched machines. Under no
circumstances may the EZ-SCREEN Type 2 be used on full-revoluon clutched machinery or in unsuitable
applicaons as those listed. If there is any doubt about whether or not your machinery is compable with the
EZ-SCREEN Type 2, contact Banner Engineering.

CAUTION: Use of EZ-SCREEN Type 2
EZ-SCREEN Type 2 meets the Type 2 requirements of IEC 61496 and Category 2 PLc requirements of EN ISO
13849-1. DO NOT use EZ-SCREEN Type 2 unless it is installed, tested, and inspected in accordance with this
manual. DO NOT use EZ-SCREEN Type 2 where Control Reliability is required, or where Category 3, Category 4, or
Type 4 AOPD (acve opto-electronic protecve device) have been mandated, or where a risk assessment has
determined that frequent access by personnel to the hazard could result in an irreversible or serious injury (for
example, OSHA reportable injury).
Typical use is for safeguarding in situaons where the consequence of an accident will result in only slight
(normally reversible) injuries that are typically treated by the normal healing processes and minor medical
treatment (that is, rst aid, as dened by OSHA 29CFR1904.7).
Failure to follow these instrucons could result in serious bodily injury or death.
2.3.1 Examples: Appropriate Applicaons
EZ-SCREEN Type 2 are typically used for, but is not limited to, the following applicaons (dependent on machine risk assessment):
• Small assembly equipment
• Automated producon equipment
• "Table-top" roboc work cells
• Component inseron/"pick-and-place" machines
• Small packaging machines
• Equipment and process protecon (non-personnel safety)
•Applicaons that could result in only slight (normally reversible) injuries (such as bump, bruise, knock-down, trapping but not
crushing, minor cuts and abrasions, etc.)
2.3.2 Examples: Inappropriate Applicaons
Do not use EZ-SCREEN Type 2 in the following applicaons:
• As a primary safeguard in frequently accessed hazardous situaons that could result in serious injuries (normally irreversible,
including death)
• In any case where Control Reliability, Category 3, Category 4, or Type 4 AOPD (acve opto-electronic protecve device) have
been mandated. See EN ISO 13849-1, IEC 61496-1, or other appropriate standard
• With any machine that cannot be stopped immediately aer a stop signal is issued, such as single-stroke (or full-revoluon)
clutched machinery
• With any machine with inadequate or inconsistent machine response me and stopping performance
• With any machine that ejects materials or component parts through the dened area
• In any environment that is likely to adversely aect photoelectric sensing eciency. For example, corrosive chemicals or uids
or unusually severe levels of smoke or dust, if not controlled, may degrade sensing eciency
• As a tripping device to iniate or reiniate machine moon (PSDI applicaons), unless the machine and its control system fully
comply with the relevant standard or regulaon (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 Type 2 is installed for use as a perimeter guard (where a pass-through hazard may exist, see Reducing or Eliminang
Pass-Through Hazards on page 14), the dangerous machine moon can be iniated by normal means only aer the safeguarded area
is clear of individuals and the EZ-SCREEN Type 2 has been manually reset.
2.4 Control Reliability and Safety Categories
To summarize the expected safety circuit performance in high-risk situaons, requirements of Control Reliability (OSHA 29CFR1910.217
and ANSI B11.19)) and Category 3 and Category 4 (EN ISO 13849-1) demand that a reasonably foreseeable, single failure does not lead
to the loss of the safety funcon, and does not prevent a normal or immediate stop from occurring. The failure or the fault must be
detected at or before the next demand of safety (e.g., at the beginning or end of a cycle, or when a safeguard is actuated). The safety-
related part of the control system then must issue an immediate stop command, or prevent the next machine cycle or hazardous
situaon unl the failure or fault is corrected.
The eect of ANSI B11.19, and EN ISO 13849-1 is to set a baseline for situaons in which a minimum level of performance has been
mandated or in cases where a risk assessment has determined a need for Control Reliability, Category 3 or Category 4 level of
performance.
In lower-risk safety applicaons, safeguards and safety circuits do not require the level of performance and fault tolerance described by
Control Reliability, Category 3 or Category 4. Applicaons involving situaons that could result in a slight or normally reversible injury
(e.g., only requiring rst aid, as dened by OSHA 29CFR1904) can be solved by EN ISO 13849-1 Category 2.
EN ISO 13849-1 Category 2 does not require the same level of performance and fault tolerance as required by Control Reliability,
Category 3 or Category 4. Safety-related parts of control systems designed to Category 2 “shall be designed so that their funcon(s) are
checked at suitable intervals by the machine control system.” This allows a single fault to lead to the loss of the safety funcon between
EZ-SCREEN®Type 2 Light Screen

the check [test] of the system, but the loss of safety funcon is detected by the check. By comparison, in a system designed to EN ISO
13849-1 Category 4, a single fault or an accumulaon of faults will not lead to a loss of the safety funcon.
While EN ISO 13849-1 generally applies to the machine level, IEC61496-1/-2 species requirements for the design, construcon and
tesng for two levels or “types” of acve opto-electronic protecve devices (AOPDs) or light curtains (light screens). “Type 2” and “Type
4” describe diering requirements to ensure that appropriate safety-related performance is achieved. The appropriate type is
dependent on the overall degree of risk reducon, as determined by the machine’s Risk Assessment (see ISO 12100, ANSI B11.19, or
other relevant standard).
A Type 2 AOPD relies on periodic tesng to detect a failure to danger. Between tests, a single fault can result in the loss of the safety
funcon. While this level of performance and fault tolerance is generally not allowed in Category 4 situaons, it is acceptable in the
lower-risk situaons described by Category 2.
While the EZ-SCREEN Type 2 conducts connual internal self-tests and all single faults have been considered, the installaon should
provide an addional periodic test/check of the EZ-SCREEN Type 2 and its interface to ensure the integrity of the safety funcon (see
Manual Reset/Remote Test Input and EDM on page 31). A component failure detected by periodic test/check must cause a “stop”
signal to be sent to the guarded machine and put the System into a Lockout condion.
Recovery from this type of Lockout condion requires:
• Replacement of the failed component (to restore the safety funcon)
• The appropriate reset procedure.
2.5 Operang Features
The Banner EZ-SCREEN Type 2 Light Screen models described by this manual feature standard funcons:
• Trip or Latch Output (depending on model)
• External Device Monitoring (EDM) via the Test/Retest input
The System Response Time (Tr) can be determined by the model number on the emier and receiver.
2.5.1 Trip/Latch Output
Whether a receiver features Trip or Latch Output determines whether the System will enter RUN mode automacally aer power-up, or
if it will require a manual reset rst. If the System has Trip Output, other measures must be taken to prevent a pass-through hazard.
For Latch Output models, the EZ-SCREEN Type 2 requires a manual reset for the OSSD outputs to turn ON, aer power is applied and all
beams are clear.
• For Trip Output models, the OSSD outputs will turn ON aer power is applied and the receiver passes its internal self-test/
synchronizaon and recognizes that all beams are clear. Trip Output models will also turn on aer all beams are cleared
following a blocked beam.
• For Latch Output models, the EZ-SCREEN Type 2 requires a manual reset for the OSSD outputs to turn ON, whenever power is
applied and all beams are clear.
WARNING: Use of Trip/Latch Output
Applicaon of power to the Banner device, the clearing of the dened area, or the reset of a Latch condion MUST
NOT iniate dangerous machine moon. Machine control circuitry must be designed so that one or more iniaon
devices must be engaged (in a conscious act) to start the machine – in addion to the Banner device going into
Run mode. Failure to follow these instrucons may result in serious bodily injury or death.
2.5.2 Wiring Opons for Emier/Receiver Swapability
Each EZ-SCREEN Type 2 sensor can be connected to its own power supply or, color-for-color to the other sensor’s cable. The color-for-
color hookup allows the emier and receiver posions to be interchanged without rewiring (funconality known as sensor "
swapability"). Model CSB.. splier cordsets and DEE2R.. double-ended cables facilitate interconnecon between an EZ-SCREEN Type 2
receiver and emier, providing a single "homerun" cable for oponal swapable hookup.

2.5.3 Manual Reset/Remote Test Input and EDM
A single input provides the means to reset the system from a latch or lockout condion, to externally test the light screen and its
interface, and to monitor external devices (EDM) for proper operaon. If the System is in Run condion with outputs ON, operang the
switch results in a test. If the System is Latched or Locked Out, operang the switch results in a reset.
External Device Monitoring (EDM)
This feature allows the EZ-SCREEN Type 2 system to monitor the status of external devices such as MPCEs. A normally closed and a
normally open contact from each monitored device are wired in series-parallel to detect if one of the devices fails.
2.5.4 Status Indicators
Status indicators on both the emier and receiver are clearly visible on each sensor’s front panel.

3 Mechanical Installaon
The EZ-SCREEN Type 2 system performance as a safety guarding device depends on:
• The suitability of the applicaon
• The proper mechanical and electrical installaon and interfacing to the guarded machine
WARNING: Read this Secon Carefully Before Installing the System
If all mounng, installaon, interfacing, and checkout procedures are not followed properly, the Banner device
cannot provide the protecon for which it was designed. The user has the responsibility to ensure that all local,
state, and naonal laws, rules, codes, or regulaons relang to the installaon and use of this control system in
any parcular applicaon are sased. Ensure that all legal requirements have been met and that all technical
installaon and maintenance instrucons 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 Qualied Persons2, in accordance with this manual and applicable safety regulaons.
3.1 Mechanical Installaon Consideraons
The two primary factors that inuence the layout of the EZ-SCREEN Type 2 system mechanical installaon are the Safety Distance
(Minimum Distance) (see Calculang the Safety Distance (Minimum Distance) on page 11) and the supplemental safeguarding/
eliminang pass-through hazards (see Reducing or Eliminang Pass-Through Hazards on page 14). Other consideraons include:
•Emier and Receiver Orientaon on page 17
•Adjacent Reecve Surfaces on page 16
•Use of Corner Mirrors on page 16
•Installaon of Mulple Systems on page 18
WARNING: Posion Components Carefully
The emier and receiver must be posioned such that the hazard cannot be accessed by reaching over, under,
around, or through the sensing eld. Addional and supplemental guarding may be required.
3.1.1 Calculang the Safety Distance (Minimum Distance)
Safety Distance (Ds), also called Minimum Distance (S), is the minimum distance required between the dened 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 Type 2 sends a stop signal to the machine, causing it to stop by the me the object or person can reach any machine hazard
point.
The distance is calculated dierently for U.S. and European installaons. Both methods take into account several factors, including a
calculated human speed, the total system stopping me (which itself has several components), and the depth penetraon factor. Aer
the distance has been determined, record the calculated distance on the Daily Checkout Card.
WARNING: Safety Distance (Minimum Distance)
The Banner emiers and receivers must be mounted at a distance from the nearest hazard such that an individual
cannot reach the hazard before cessaon of hazardous moon or situaon. This distance can be calculated using
the formulas in this secon, 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 Khas 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
determinaons. Consider all factors, including the physical ability of the operator, when determining the value of Kto
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-me measuring device. If the machine manufacturer's specied stop me is used, at
least 20% should be added to allow for possible clutch/ brake system deterioraon. This measurement must take into
account the slower of the two MPCE channels, and the response me of all devices or controls that react to stop the
machine.
WARNING: Determine Correct Stop Time
Stop me (Ts) must include the response me 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 me of all relevant devices and controls in your calculaons.
If required, each of the two Machine Primary Control Elements (MPCE1 and MPCE2) must be capable of
immediately stopping the dangerous machine moon, regardless of the state of the other. These two channels of
machine control need not be idencal, but the stop me performance of the machine (Ts, used to calculate the
safety distance) must take into account the slower of the two channels.

dened area will be closer than 665.6 mm to the closest reachable hazard
point on the guarded machine.
3.1.2 Reducing or Eliminang Pass-Through Hazards
A pass-through hazard is associated with applicaons where personnel may pass through a safeguard (which issues a stop command to
remove the hazard), and then connues 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 mes, large
minimum object sensivies, reach-over, reach-through, or other installaon consideraons. A pass-through hazard can be generated
with as lile as 75 mm (3 in) between the dened area and the machine frame or hard (xed) 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 capabilies, or other applicaon consideraons.
One soluon is to ensure that personnel are connually 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 alternave method is to ensure that once the safeguarding device is tripped it will latch and will require a deliberate manual acon
to reset. This method of safeguarding relies upon the locaon of the reset switch as well as safe work pracces 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 applicaon 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 interrupon of the dened area.
The reset of this Latched condion may only be achieved by actuang a reset switch that is separate from the
normal means of machine cycle iniaon.
Lockout/Tagout procedures per ANSI Z244.1 may be required, or addional 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.

3.1.3 Supplemental Safeguarding
As described in Calculang the Safety Distance (Minimum
Distance) on page 11, the EZ-SCREEN Type 2 must be properly
posioned such that an individual cannot reach through the
dened area and access the hazard point before the machine has
stopped.
Addionally, the hazard cannot be accessible by reaching around,
under, or over the dened 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 dened area of the EZ-SCREEN Type 2
System or through other safeguarding that prevents access to the
hazard (see Figure 4 on page 15).
The mechanical barriers used for this purpose are typically called
"hard (xed) guarding"; there must be no gaps between the hard
(xed) guarding and the dened area. Any openings in the hard
(xed) guarding must comply with the safe opening requirements
of ANSI B11.19 or other appropriate standard.
Figure 4. An example of supplemental safeguarding
Figure 4 on page 15 shows an example of supplemental safeguarding inside a roboc work cell. The EZ-SCREEN Type 2, in conjuncon
with the hard (xed) guarding, is the primary safeguard. Supplemental safeguarding (such as a horizontal-mounted 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).
Addional 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 Dened Area
The installaon of the EZ-SCREEN Type 2 must prevent any individual from reaching around, under, over or
through the dened area and into the hazard without being detected. Mechanical barriers (for example, hard
(xed) 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 Other Consideraons
Reset Switch Locaon
The reset switch must be mounted at a locaon that complies with the warning and guidelines below. If any hazardous areas are not
in view from the switch locaon, addional means of safeguarding must be provided. The switch should be protected from accidental or
unintended actuaon (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
addional personnel entering the guarded area unnoced. When considering where to locate the reset switch, follow the guidelines
below.
WARNING: Reset Switch Locaon
When considering where to locate the reset switch, you must follow the guidelines outlined in this secon.
If any areas within the guarded area are not visible from the reset switch, addional safeguarding must be
provided, as described by the ANSI B11.19 series or other appropriate standards.
Failure to follow these instrucons 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 enre guarded area while the reset is performed
• Out of reach from within the guarded area
• Protected against unauthorized or inadvertent operaon (such as through the use of rings or guards).
EZ-SCREEN®Type 2 Light Screen
www.bannerengineering.com - Tel: [phone]

Important: Reseng a safeguard must not iniate hazardous moon. Safe work procedures require a start-up procedure to be
followed and the individual performing the reset to verify that the enre 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 locaon, addional supplemental
safeguarding must be used: at a minimum, visual and audible warnings of machine start-up.
Adjacent Reecve Surfaces
WARNING: Avoid Installaon Near Reecve Surfaces
Avoid locang the dened area near a reecve surface; it could reect sensing beam(s) around an object or
person within the dened area, and prevent its detecon by the EZ-SCREEN Type 2. Perform the trip test, as
described in this manual, to detect such reecon(s) and the resultant opcal short circuit. Failure to prevent
reecon problems will result in incomplete guarding and could result in serious injury or death.
A reecve surface located adjacent to the dened area may deect one or more beams around an object in the dened area. In the
worst case, an opcal short circuit may occur, allowing an object to pass undetected through the dened area.
This reecve surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the oor, or the
walls. Beams deected by reecve surfaces are discovered by performing the trip test and the periodic checkout procedures. To
eliminate problem reecons:
• If possible, relocate the sensors to move the beams away from the reecve surface(s), being careful to maintain adequate
separaon distance
• Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reecvity
• Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resoluon resulng from
the opcal short circuit and use the corresponding depth penetraon factor (Dpf or C) in the Safety Distance (Minimum
Distance) formula; or mount the sensors in such a way that the receiver's eld of view and/or the emier's spread of light are
restricted from the reecve surface
• Repeat the trip test (see Trip Test on page 28) to verify that these changes have eliminated the problem reecon(s). If the
workpiece is especially reecve and comes close to the dened area, perform the trip test with the workpiece in place

Use of Corner Mirrors
EZ-SCREEN Type 2 may be used with one or more corner mirrors. Mirrors are not allowed for applicaons that would allow undetected
personnel access into the safeguarded area. The use of glass-surface corner mirrors reduces the maximum specied emier/receiver
separaon by approximately 8 percent per mirror, as follows:

If mirrors are used, the dierence between the angle of incidence from the emier to the mirror and from the mirror to the receiver
must be between 45° and 120° (see Figure 6 on page 17). If placed at a sharper angle, an object in the light screen may deect
beam(s) to the receiver, prevenng the object from being detected, also know as false proxing. Angles greater than 120° result in
dicult alignment and possible opcal short circuits.
WARNING: Avoid Retroreecve Installaon
Do not install emiers and receivers in "retroreecve" mode, with less than a 45° angle of incidence, as shown.
Sensing may be unreliable in this conguraon and result in a serious bodily injury or death.

Emier and Receiver Orientaon
The emier and receiver must be mounted parallel to each other and aligned in a common plane, with both machine interface cable
ends poinng in the same direcon. Never mount the emier with its machine interface cable end oriented in the opposite direcon of
the cable end of the receiver. If this occurs, voids in the light screen may allow objects or personnel to pass through the dened area
undetected.
The emier and receiver may be oriented in a vercal or horizontal plane, or at any angle between horizontal and vercal, as long as
they are parallel to each other and their cable ends point in the same direcon. Verify that the light screen completely covers all access
to the hazard point that is not already protected by hard (xed) guarding or other supplemental guarding.
WARNING: Proper Orientaon of System Emiers and Receivers
EZ-SCREEN Type 2 emiers and receivers must be installed with their corresponding cabled ends poinng in the
same direcon (for example, both cabled ends facing up). Failure to orient them properly will impair the
performance of the EZ-SCREEN Type 2 System and will result in incomplete guarding, and could result in serious
bodily injury or death.

Installaon of Mulple Systems
Whenever two or more EZ-SCREEN Type 2 emier and receiver pairs are adjacent to one another, opcal crosstalk may take place
between the systems. To minimize opcal crosstalk, alternate the posions of the emiers and receivers (see Figure 9 on page 19).
When three or more systems are installed in the same plane (as shown in Figure 9 on page 19), opcal crosstalk may occur between
sensor pairs whose emier and receiver lenses are oriented in the same direcon. In this situaon, eliminate opcal crosstalk by
mounng these sensor pairs exactly in line with each other within one plane, or by adding a mechanical barrier between the pairs.

WARNING: Mulple Pairs of Sensors
Do not connect mulple pairs of sensors to one Interface Module (for example, IM-T-9A/-11A) or otherwise
parallel OSSD outputs. Connecon of mulple OSSD safety outputs to a single device may result in serious bodily
injury or death, and is prohibited.
WARNING: Synchronizaon
In situaons where mulple systems are mounted closely together, or where a secondary emier is in view
(within ±5°), within range of an adjacent receiver; a receiver may synchronize to the signal from the wrong
emier, reducing the safety funcon of the light screen.

Mounng Hardware
The EZ-SCREEN standard end-cap mounng bracket hardware is
supplied with each emier and receiver. Brackets are designed to
mount directly to MSA Series stands using the hardware with the
supplied stands.
Figure 10. Emier and Receiver End-Cap Mounng Brackets
Using Center Mounng Brackets
Center mounng brackets are supplied with longer sensors and
must be used whenever the sensors are subject to shock or
vibraon. The sensors are designed to be mounted with up to 450
mm (18 in) distance between brackets:
• Sensors 600 to 900 mm (24 in to 36 in) long are supplied
with one center bracket, which should be centered on the
sensor.
• Sensors 1050 to 1350 mm (42 in to 54 in) long are
supplied with two center brackets, which should be
posioned 1/3 of the sensor's length from each sensor
end.
• Sensors 1500 to 1800 mm (59 in to 71 in) long are
supplied with three center brackets
To install each bracket:
1. Spread the clamp and snap over the back of the sensor so
that the clamp is securely fastened to the sensor without
blocking any beams.
2. Compress the foam spacer and slide the clamp along the
length of the sensor housing to align the clamp with the
center mounng bracket as shown in Figure 11 on page
20. Three separate mounng holes are provided on the
clamp to allow for all possible mounng conguraons.
3. Connect the clamp to the center bracket using the M3
screw supplied.
4. Loosen all the mounng screws to the sensor, align the
sensors and then ghten the end screws. Finally, ghten
the M3 screw joining the clamp to the center mounng
bracket.

3.2.2 Mounng and Inial Alignment of Emier/Receiver Pairs
Emier/receiver pairs may be spaced from 0.2 to 15 m (8 in to 50 ) apart. The maximum distance between an emier and its receiver
is reduced if corner mirrors are used. The supplied brackets (when mounted to the sensor end caps) allow ±30° rotaon.
To mount each emier/receiver pair:
1. From a common point of reference (ensuring the calculated safety distance), make measurements to locate the emier and
receiver in the same plane with their midpoints directly opposite each other.
