EZ-SCREEN LP
Instruction Manual
Overview
Overview
1. Overview
1.1 Introduction
Banner EZ-SCREEN LP emitters and receivers provide
a redundant, microprocessor-controlled, opposed-mode
optoelectronic “curtain of light,” or “safety light screen.”
EZ-SCREEN LP typically is used for point-of-operation
safeguarding, and is suited to safeguard a variety of machinery.
Emitters have a row of synchronized modulated infrared
(invisible) light-emitting diodes (LEDs) in a compact metal
housing. Receivers have a corresponding row of synchronized
photodetectors. The light screen 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
low-profile housing provides maximum sensing
within minimum space; its defined area (sensing
area) is equivalent to the height of the housing.
The maximum sensing range is 7 m (23'), which
decreases if corner mirrors are used. The sensing
area extends from end to end of the housing; there
is no “dead zone.” Specialty brackets allow easy
mounting of cascaded sensors, without any loss of
resolution between sensor pairs.
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 will turn OFF. These safety outputs are
connected to the guarded machine’s final switching devices
(FSDs) that control the primary control elements (MPCEs), which
immediately stop the motion of the guarded machine.
Electrical connections (power, ground, inputs and outputs)
are made via M12 (Euro-style) quick-disconnects or unique
RD (removable disconnect) cordsets, depending on model. A
“System” as referred to in this manual may be defined as an
emitter and its receiver, plus their cabling, or to a cascade of
emitters and their receivers and their cabling.
Functions such as Trip/Latch select, Display Invert, Cascading,
Fixed Blanking (including Remote Teach), Reduced Resolution
(Floating Blanking), Scan Code select, and External Device
Monitoring are described in Section 1.4. An auxiliary (aux.)
output may be used to signal the state of the OSSDs to a
process controller; see Section 1.4.3. All models require
a supply voltage of +24V dc ±15%. See Section 2.4 for
interfacing solutions.
Both emitter and receiver feature 7-segment Diagnostic
Displays and individual LEDs to provide continuous indication
of operating status, configuration and error conditions. See
Section 1.4.7 for more information.
This manual contains numerous WARNING and CAUTION
statements. Warnings refer to situations that could lead to
significant or serious personal injury or death. Cautions refer to
situations that could lead to slight personal injury or potential
damage to equipment.
EZ-SCREEN LP is extensively FMEA (Failure Mode and Effects
Analysis) tested to establish an extremely high degree of
confidence that when properly installed, no system component
will (even if it should fail) cause a failure to danger.
The OSSD safety outputs are capable of performing a
“handshake” communication with the muteable safety stop
interface (MSSI) or universal safety stop interface (USSI) found
on other Banner Engineering safety products.
Banner EZ-SCREEN LP is a two-piece (“two-box”) system –
comprising an emitter and a receiver, but no external controller.
The external device monitoring (EDM) function ensures the
fault detection capability required by U.S. Control Reliability and
ISO13849-1 Categories 3 and 4 without a third box, a controller
or a “smart” (i.e., self-checking) safety module required of
systems without EDM.

Overview
1.2 Applications and Limitations
The Banner EZ-SCREEN LP is intended for point-of-operation
machine guarding applications 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.
Before installing the EZ-SCREEN LP, read this manual
in its entirety, paying particular attention to this section
and all of Section 3. The EZ-SCREEN LP’s 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 LP
cannot provide the protection for which it was designed.
EZ-SCREEN LP is typically used, but is not limited to, the
following applications:
•Smallassemblyequipment
•Moldingandpowerpresses
•Automatedproductionequipment
•Roboticworkcells
•Assemblyandpackagingmachines
•Leanmanufacturingsystems
EZ-SCREEN LP may NOT be used with the following
machinery or unsuitable applications:
•Anymachinethatcannotbestoppedimmediatelyafterastop
signal is issued, such as single-stroke (or “full-revolution”)
clutched machinery.
•Anymachinewithinadequateorinconsistentmachine
response time and stopping performance.
•Anymachinethatejectsmaterialsorcomponentpartsthrough
the defined area.
•Inanyenvironmentthatislikelytoadverselyaffect
photoelectric sensing efficiency. For example, corrosive
chemicals or fluids or unusually severe levels of smoke or
dust, if not controlled, may degrade sensing efficiency.
•Asatrippingdevicetoinitiateorreinitiatemachinemotion
(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, ANSI/
RIA R15.06, ISO 12100, IEC 60204-1, IEC 61496, or other
appropriate standard).
If an EZ-SCREEN LP is installed for use as a perimeter guard
(i.e., where a pass-through hazard may exist), the dangerous
machine motion can be initiated by normal means only
after the safeguarded area is clear of individuals and the
EZ-SCREEN LP has been manually reset. See Section 3.1.2.
EZ-SCREEN LP
Instruction Manual
WARNING . . . Read this Section Carefully
Before Installing the System
The user is responsible for satisfying all local, state, and national
laws, rules, codes, or regulations relating to the installation and
use of this control system in any particular application. Take
extreme care to meet all legal requirements and follow all installation
and maintenance instructions contained in this manual.
The user has the sole responsibility to ensure that the
EZ-SCREEN LP is installed and interfaced to the guarded
machine by Qualified Persons in accordance with this manual
and applicable safety regulations.
Carefully read this manual in its entirety, paying particular attention to
Section 1.2 and all of Section 3, before installing the System. Failure
to follow these instructions could result in serious bodily injury
or death.
WARNING . . . Install EZ-SCREEN LP Only
on Appropriate Applications
Banner EZ-SCREEN LP 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 EZ-SCREEN LP be used
on full-revolution clutched machinery or in unsuitable applications
as those listed at left. If there is any doubt about whether or not
your machinery is compatible with EZ-SCREEN LP, contact
Banner’s Application Engineers at the factory.
1.3 Control Reliability: Redundancy and Self-Checking
Redundancy requires that EZ-SCREEN LP 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 LP is
designed with redundant microprocessors.
Redundancy must be maintained whenever the EZ-SCREEN
LP is in operation. Because a redundant system is no longer
redundant after a component has failed, EZ-SCREEN LP 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
EZ-SCREEN LP into a Lockout condition.
RecoveryfromthistypeofLockoutconditionrequires:
•replacementofthefailedcomponent(torestoreredundancy)
and
•theappropriateresetprocedure(seeSection1.4.8).
The Diagnostic Display is used to diagnose causes of a Lockout
condition (see Section 5.1).

Instruction Manual
1.4 Operating Features
The Banner EZ-SCREEN LP models described by this manual
featureseveralstandardselectablefunctions:
•ReducedResolution(FloatingBlanking),
•TriporLatchOutput,
•ExternalDeviceMonitoring(EDM),
•AuxiliaryOutput— OSSD Follow or Fault,
•ScanCodesetting,
•FixedBlanking(includingRemoteTeach),
•EmitterTestandFaultfunctions,
•InvertedDisplay,and
•Cascading(availableonSLPC..models).
These functions are configured via DIP switches (behind the
access door on the front of each sensor) and the sensor wiring
configuration; see Sections 3 and 4.2 for more information.
The sensing resolution is determined by the emitter and receiver
model. See Section 2 for a list of model numbers.
1.4.1 Selectable Trip/Latch Output
The setting for Trip or Latch Output determines whether the
System will enter RUN mode automatically after power-up, or if
it will require a manual reset first (see Sections 1.4.8 and 4.2). If
the System is set for Trip Output, other measures must be taken
to prevent a pass-through hazard; see Section 3.1.2 and the
warning below for more information.
If Trip Output is selected, the OSSD outputs will turn ON after
power is applied and the receiver passes its internal self-test/
synchronization and recognizes that all beams are clear. They
will also automatically reset after all beams are cleared. If Latch
Output is selected, the EZ-SCREEN LP requires a manual reset
for the OSSD outputs to turn ON, whenever power is applied
(and all beams are clear), or following a blocked beam (see
Section 4.5).
WARNING . . . Use of Trip/Latch Output
Application of power to the EZ-SCREEN LP components, the
clearing of the defined area, or the reset of a Latch condition
MUST NOT initiate dangerous machine motion. Machine control
circuitry must be designed so that one or more initiation devices
must be engaged (i.e., a conscious act) to start the machine – in
addition to the EZ-SCREEN LP going into RUN mode. Failure to
follow these instructions could result in serious bodily injury
or death.
Overview
Overview
1.4.2 Emitter Hookup Options
An EZ-SCREEN LP emitter can be connected either to its
own power supply or to the receiver cable, color-for-color (see
Figures 3-19 and 3-20). The color-for-color hookup allows
the emitter and receiver positions to be interchanged without
rewiring. If the color-for-color hookup is used, however, the
emitter Test function is not available.
1.4.3 External Device Monitoring (EDM)
This feature allows the EZ-SCREEN LP to monitor the status
of external devices, such as MPCEs. The choices are 1- or
2-channel monitoring, or no monitoring. EDM is used when the
EZ-SCREEN LP’s OSSD outputs directly control the MPCEs
or other external devices; see Sections 3.5.3 and 4.2 for more
information.
Auxiliary (Aux.) Output; OSSD Follow/Fault
An aux. output function is available when the receiver is
configured for 1-channel EDM. This current sourcing (PNP)
solid-state output (250 mA max.) is used for control functions
that are not safety-related; a typical use is to signal the state
of the OSSDs to a programmable logic controller (PLC). The
aux. output either follows the state of the OSSDs or provides
a fault signal (lockout = ON). DIP switch configuration and pin
2 (orange/black) connection configure this feature; see Section
3.5.5 and Figure 3-26. See Section 4.2 for information on the
emitter Fault function.
1.4.4 Remote Test Input
EZ-SCREEN LP emitters provide a Test function, selectable
by DIP switch. An external switch, typically a normally open
contact, held closed, is connected between the emitter and
24V dc (see Section 3.5.4). Opening the switch “turns off” the
emitter, simulating an interruption of one or more light beams.
This function may be useful for EZ-SCREEN LP setup and to
verify machine control circuit operation.
NOTE:TheemitterTestfunctioncannotbeusedinacolor-forcolor (“swapable”) hookup (see Figure 3-22).
1.4.5 Scan Code Configuration
The emitter and receiver may be configured to one of two Scan
Code positions (1 or 2); a receiver will recognize beams only
from an emitter with the same setting. This helps minimize the
effects of crosstalk between multiple emitter/receiver pairs, and
allows multiple pairs to operate in close proximity in certain
situations. See Sections 3.1.5 and 3.1.8 for proper mounting
configurations. The Scan Code is set via DIP switch on each
sensor; see Section 4.2 for more information. Both the emitter
and its corresponding receiver must have the same setting.

Instruction Manual
Overview
1.4.6 Reduced Resolution (Floating Blanking)
Reduced Resolution increases the minimum diameter of an
object that the light screen can reliably detect anywhere within
its defined area. Reduced Resolution is generally used to allow
one or more objects (usually workpiece materials) to move
anywhere through the defined area, without tripping the OSSD
safety outputs.
Enabling two-beam Reduced Resolution reduces the overall
minimum object sensitivity, which allows multiple objects to
move through the defined area (see Section 3.4.2). The effect is
that any two consecutive beams (except for the sync beam) can
be blocked, without causing the OSSDs to turn OFF. This is also
called “Multiple-Point Floating Blanking.”
Resolution directly affects the minimum allowable distance
between the defined area of a light screen and the nearest
Beams of
Defined Area
hazard point (separation distance, see Section 3.1.1). The
receiver’s Green status indicator flashes when Reduced
Resolution is enabled. The ignored object size and resultant
Reduced Resolution are listed in Section 3.4.2.
1.4.7 Status Indicators
Status indicators on both the emitter and receiver are clearly
visible on each sensor’s front panel.
Bi-color red/green Status indicator – shows whether power is
applied, and whether the emitter is in RUN mode, TEST mode,
or Lockout condition.
1-Digit Diagnostic Display – indicates specific error or
configuration conditions.
Bi-color red/green Zone indicators – show status of a group of
beams:
- aligned and clear (green ON), or
- blocked and/or misaligned (red ON), or
- fixed blanked area (flashing green).

EZ-SCREEN LP
Instruction Manual
1.4.8 Manual Resets and Lockout Conditions
Reset Routine
The EZ-SCREEN LP requires a manual reset to clear a PowerUp Lockout or Latch condition, and after correcting the cause
of a Lockout condition. This function is designed to provide a
“monitored manual reset” (i.e., open-closed-open action), such
that a shorted or tied-down button cannot cause a reset. When
a key-operated switch is used, this is typically called a key reset.
(Reset switch is sold separately; see Section 2.4 for options.)
To perform a manual reset, close the normally open switch for
at least 1/4 second, but no longer than 2 seconds, and then
re-open the switch. See Sections 3.1.3 and 4.3 for further
information.
A Lockout condition will cause the EZ-SCREEN LP OSSD
outputs to turn OFF. A Lockout condition is indicated by a
flashing Red emitter or receiver Status indicator and an error
number displayed on the Diagnostic Display. Lockout conditions
require a manual reset routine to return the system to RUN
mode after the failure has been corrected. A description of
possible lockouts, their causes, and troubleshooting hints are
listed in Section 5.
Trip Output/Auto Reset
While the use of a reset switch is recommended, it is not
required for receivers configured for Trip Output (automatic
reset). Cycling the supply power (OFF for > 2 seconds, then ON)
will also clear lockouts if their cause has been corrected. If a
reset switch is not used, leave pin 8 (violet wire) not connected
(open) and secure it against shorting to a source of power or
ground.
Overview
Overview
1.4.10 Inverted Display
A DIP switch can be used to invert the seven-segment display.
This makes the display “right reading” when an emitter and
receiver are mounted with the QD connector ends up (upside
down). See Section 4.4 for more information.
1.4.11 Cascadeable Models
Emitter and receiver models SLPC.. (see Section 7) are capable
of interconnecting up to four emitter/receiver pairs – regardless
of the resolution, the total number of beams, or the size of the
defined area. EZ-SCREEN SLPC.. (cascadeable) models can
also be used individually as stand-alone systems. They also can
be cascaded with EZ-SCREEN SLSC.. models.
Double-ended RD-style 24 AWG cordsets (listed in Section
2.3) are required for connecting sensors in a cascade; see
Section 7.4 for maximum cable lengths. (RD-to-QD cordsets are
available to connect between SLPC.. and SLSC.. models.)
Maximum system response time for a cascade is dependent on
the number of beams in each light screen, and the light screen’s
positioninthecascade.Itcanbecalculatedintwoways:
•Individuallyforeachlightscreeninthecascade(safety
distance is calculated for each light screen in the cascade), or
•Basedontheworst-casemaximumfortheentirecascade
(all light screens in the cascade have the same separation
distance).
See Section 7.5 for more information.
1.4.9 Fixed Blanking
The fixed blanking feature allows for a stationary object(s)
positioned in the defined area, such as tooling, to be ignored. A
flashing Green Zone indicator denotes the location of a blanked
area. If the object is either moved or removed, the System goes
into Lockout mode, ensuring that an unexpected hole in the
sensing field is not created.
Fixed blanking is easily configured, simply by positioning the
object(s), flipping two DIP switches and resetting the System, as
described in Section 3.4.3.
For cascade models (either when used alone, or as the last
receiver in a cascade), fixed blanking may be configured
remotely; see Section 7.10 for details. This feature is useful
when the light screen is in a difficult-to-access location, or when
the fixed blanked area changes frequently.
Figure 1-4. Fixed-angle brackets allow easy cascading while
maintaining 25 mm resolution

2. Components and Specifications
An EZ-SCREEN LP “System” refers to a compatible emitter and
receiver (equal length and resolution; available separately or in
pairs), and cordset(s) for each. It also refers to the emitters and
receivers in a cascade, and their cabling. Mounting hardware
is included with each emitter and receiver; special-purpose
accessory brackets are also available, both for standalone pairs
and for cascades. Interfacing solutions include IM-T-.. modules,
redundant positively guided contactors, and muting modules;
see Section 2.4. See Sections 7.2 and 7.3 for cascadeable
models.
Models are listed in the tables either with a 300 mm (1') pigtail
with 8-pin Euro-style QD termination or with the integral RD
connection (no cordset included). The 13 mm (0.5") minimum
bend radius for all cordset models accommodates low-clearance
installations; cords can exit to left, right, or back of sensor,
when mounting. The pigtail QD option is useful for connection to
splitter cables or other QD cordsets.
Standard models (listed in the following tables) feature a yellow
painted aluminum housing. Clear anodized (silver colored)
housing finish is also available; contact the factory for more
information. Both housing colors have black endcaps.
Electro-static dissipative (ESD-safe) models with nickelplated housing and endcaps are also available. Their staticdissipative polymer coating protects nearby components
from damaging ESD voltages. Contact the factory for more
information.

Machine interface cordsets provide power to the first emitter/
receiver pair. Sensor interconnect cables provide power to
subsequent emitters and receivers in the cascade. Only cordsets
with yellow PVC cable and black overmolds are listed; for
cordsets with black PVC cables and overmolds, add suffix “B” to
the model number (e.g., RDLP-815DB).
A removable disconnect (RD) fitting is required to connect
directly to the sensor housing. QD fittings are used for cable-tocable interconnections and connections with other devices.

EZ-SCREEN LP
Instruction Manual
Installation and Overview
Alignment
3. Installation and Alignment
Before installing the EZ-SCREEN LP, read Section 1.2 and
Section 3 of this manual in their entirety. The System’s
ability to perform its safety guarding 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 System
cannot provide the protection for which it was designed.
Installation must be performed by a Qualified Person, as defined
in Section 4.1. See Warning below.
WARNING . . . Read this Section Carefully
Before Installing the System
The user is responsible for satisfying all local, state, and
national codes and regulations relating to the installation and
use of this control system in any particular application. Take
extreme care to meet all legal requirements and follow all technical
installation and maintenance instructions contained in this manual.
The user has the sole responsibility to ensure that the
EZ-SCREEN LP System is installed and interfaced to the
guarded machine by Qualified Persons in accordance with this
manual and with applicable safety regulations.
Read Section 1.2 and all of Section 3 of this manual carefully before
installing the System. Failure to follow these instructions could
result in serious bodily injury or death.
3.1 Mechanical Installation Considerations
The two factors that most influence the layout of the
EZ-SCREEN LP’s mechanical installation are safety (minimum)
distance and hard guarding. Other considerations include emitter
and receiver orientation, adjacent reflective surfaces, use of
corner mirrors, and installation of multiple EZ-SCREEN LP
emitter/receiver pairs.
3.1.1 Safety Distance (Minimum Distance)
Separation or 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 LP will
send a stop signal to the machine, causing it to stop before the
person can reach any machine hazard point.
The distance is calculated differently for domestic 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 is determined,
record the calculated distance on the Daily Checkout Card.
WARNING . . . Minimum Safety Distance
EZ-SCREEN LP 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.
Failure to establish and maintain the minimum distance could
result in serious bodily injury or death.
Reduced Resolution
Reduced Resolution increases Dpf (or C). Increase the depth
penetration factor to calculate proper minimum distance
whenever Reduced Resolution is used. Always turn Reduced
Resolution OFF when the larger minimum object detection size is
not required.

EZ-SCREEN LP
Instruction Manual
Installation
Overview and Alignment
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/minimum 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.
Notice Regarding MPCEs
Each of the machine primary control elements (MPCE1
and MPCE2) must be capable of immediately stopping
the dangerous machine motion, regardless of the state of
the other. The two machine control channels need not be
identical, but the machine’s stop time performance (Ts,
used to calculate separation distance) must be based on
the slower of the two channels (see Section 3.5.3).
The safety (separation) distance formula for U.S. applications:
Ds = K x (Ts + Tr) + Dpf
The minimum distance formula for European applications:
S = (K x T) + C
where:
Ds – the safety distance, in mm (inches);
K – 1600 mm per second (or 63" per second), the OSHA1910.217,
ANSI B11, ANSI/RIA R15.06 hand-speed constant (see Note
1);
Ts – the overall stop time of the machine (in seconds) from the
initial “stop” signal to the final ceasing of all motion, including
stop times of all relevant control elements (e.g., interface
modules) and measured at maximum machine velocity (see
Note 2 and Warning on page 21).
Tr – the maximum response time, in seconds, of the EZ-SCREEN
LP emitter/receiver pair (depending on model); and
Dpf – the added distance due to depth penetration factor as
prescribed in OSHA1910.217, ANSI B11, ANSI/RIA R15.06 for
U.S.applications(seeWarning):
where:
S – the minimum distance, in mm, from danger zone to light screen
center line; minimum allowable distance is 100 mm (175 mm for
non-industrial applications), regardless of calculated value.
K – hand-speed constant (see Note 1);
2000 mm/s for minim m safet istan es 00 mm)
1600 mm/s (for minimum safety distances > 500 mm)
T – the overall machine stopping response time (in seconds), from
the physical initiation of the safety device and the machine
coming to a stop (or the hazard removed). This can be broken
downintotwoparts:Ts or Tr, where T = Ts + Tr
Ts – the overall stop time of the machine (in seconds) from the initial
“stop” signal to themachine coming to a stop (or the risk being
removed), including stop times of all relevant control elements
(e.g., interface modules) and measured at maximum machine
velocity (see Note 2 and Warning on page 21).
Tr – the maximum response time, in seconds, of the EZ-SCREEN
LP emitter/receiver pair, depending on model; and
C – the additional distance, in mm, based on intrusion of hand or
object towards danger zone prior to actuation of a safety device.
Calculateusingtheformula:C = 8 x (d – 14) where d is the
resolution of the device (for d < 40 mm) or use 850 mm for C.

NOTES:
1. The OSHA-recommended hand speed constant K has been determined by various
studies, and although these studies indicate speeds of 63"/second to more than 100"/
second, 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. Ts is usually measured by a stop-time measuring device. If the machine manufacturer’s
specified stop time is used, add at least 20% 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. See Notice Regarding MPCEs. If all devices are not included, the calculated
safety distance (Ds) will be too short and serious injury could result.
Example: U.S. Applications, Model SLSP14-550
K = 63" per second (the hand speed constant set by OSHA)
Ts = 0.32 (0.250 second specified by machine manufacturer; plus
20% safety factor; plus 20 ms interface module response)
Tr = 0.0165 second (the specified SLSP14-550 response time)
Dpf = 3.6" (14 mm resolution, Reduced Resolution ON)
Substitutethenumbersintotheformulaasfollows:
Ds = K x ( Ts + Tr ) + Dpf
Ds = 63 x (0.32 + 0.0165) + 3.6 = 24.8"
Mount this EZ-SCREEN LP emitter and receiver so that no part of
the defined area will be closer than 24.8" to the closest reachable
hazard point on the guarded machine.
NOTES:
1. 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.
2. Ts is usually measured by a stop-time measuring device. If the machine manufacturer’s
specified stop time is used, add at least 20% 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. See Notice Regarding MPCEs. If all devices are not included, the calculated
minimum distance (S) will be too short and serious injury could result.
Example: European Applications, Model SLSP14-550
K = 1600 mm per second
T = 0.32 (0.250 second specified by machine manufacturer; plus
20% safety factor; plus 20 ms interface module response), plus
0.0165 second (the specified SLSP14-550 response time)
C = 8 x (34-14) = 160 mm (14 mm resolution, Reduced Resolution ON)
Substitutethenumbersintotheformulaasfollows:
S = ( K x T ) + C
S = (1600 x 0.3365) + 160 = 698.4 mm
Mount this EZ-SCREEN LP emitter and receiver so that no part
of the defined area will be closer than 698.4 mm to the closest
reachable hazard point on the guarded machine.

EZ-SCREEN LP
Instruction Manual
3.1.2 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 safety light screens, a pass-through hazard
typically results from large separation distances calculated
from long stopping times, large minimum object sensitivities,
reach-over, reach-through, or other installation considerations.
A pass-through hazard can be generated with as little as 75 mm
(3") between the defined area and the machine frame or hard
guarding.
Reducing or Eliminating Pass-Through Hazards
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
ANSI B11 series of safety requirements or other appropriate
standards (see Section 3.1.4).
An alternate 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 (see Section 3.1.3).
WARNING . . . Use of EZ-SCREEN LP for
Perimeter Guarding
If an EZ-SCREEN LP System is installed in an application that
results in a pass-through hazard (e.g., perimeter guarding), either the
EZ-SCREEN LP 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. The switch must be positioned as described
in Section 3.1.3.
Lockout/Tagout procedures per ANSI Z244.1 may be required,
or additional safeguarding, as described by ANSI B11 safety
requirements or other appropriate standards, must be used if a passthrough hazard can not be eliminated or reduced to an acceptable
level of risk. Failure to observe this warning could result in
serious bodily injury or death.
Installation and Overview
Alignment
3.1.3 Reset Switch Location
The reset switch must be mounted at a location that
complies with the warning 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 (e.g., 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.
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 can not be
observed from the reset switch location, additional supplemental
safeguardingmustbeused:ataminimum,visualandaudible
warnings of machine start-up.
WARNING . . . Reset Switch Location
Allresetswitchesmustbe:
•Outsidetheguardedarea,
•Locatedtoallowtheswitchoperatorfull,unobstructedviewofthe
entire guarded area while the reset is performed,
•Outofreachfromwithintheguardedarea,and
•Protectedagainstunauthorizedorinadvertentoperation(suchas
through the use of rings or guards).
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 series or other appropriate standards. Failure to
do so could result in serious injury or death.
3.1.4 Supplemental Safeguarding
As described in Section 3.1.1, the EZ-SCREEN LP components
must be properly positioned such that an individual can not
reach through the defined area and access the hazard point
before the machine has stopped.
Additionally, the hazard can not 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 safety requirements or
other appropriate standards, must be installed. Access will then
be possible only through the defined area of the EZ-SCREEN
LP or through other safeguarding that prevents access to the
hazard (see Figure 3-3).

EZ-SCREEN LP
Instruction Manual
Installation
Overview and Alignment
The mechanical barriers used for this purpose are typically
called “hard guarding”; there must be no gaps between the
hard guarding and the defined area. Any openings in the hard
guarding must comply with the safe opening requirements of
ANSI B11 or other appropriate standard.
WARNING . . . The Hazard Must Be
Accessible Only through the Defined Area
The installation of the EZ-SCREEN LP must prevent any
individual from reaching around, under, over or through the
defined area and into the hazard without being detected.
Mechanical barriers (e.g., hard guarding) or supplemental
safeguarding may be required to comply with this requirement, and
is described by ANSI B11 safety requirements or other appropriate
standards.
3.1.5 Emitter and Receiver Orientation
The emitter and receiver must be mounted parallel to each other
and aligned in a common plane, with both cable ends pointing
in the same direction. Never mount the emitter with its cable
end oriented opposite 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 (see
Figure 3-4).
The emitter and receiver may be oriented in a vertical or
horizontal plane, or at any angle between horizontal and vertical,

Figure 3-3 shows an example of supplemental safeguarding
inside a robotic work cell. The EZ-SCREEN LP, in conjunction
with the hard guarding, is the primary safeguard. Supplemental
safeguarding (such as a horizontal-mounted safety light screen
as an area guard) is required in areas that can not be viewed
from the reset switch (i.e., behind the robot and the conveyor).
Additional supplemental safeguarding may be required to
prevent clearance or trapping hazards (e.g., the safety mat
as an area guard between the robot, the turntable, and the
conveyor).
WARNING . . . Proper Orientation of
EZ-SCREEN LP Emitters and Receivers
EZ-SCREEN LP emitters and receivers must be installed with
their corresponding cabled ends pointing in the same direction
(e.g., both cabled ends “up”). Failure to orient them properly will
impair the performance of the EZ-SCREEN LP and will result in
incomplete guarding, and could result in serious bodily injury
or death.

3.1.6 Adjacent Reflective Surfaces
A reflective surface 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 (see Figure
3-6).
This reflective surface may result from shiny surfaces or glossy
paint on the machine, the workpiece, the work surface, the floor
or the walls. Discover beams deflected by reflective surfaces by
performing the trip test portion of the final alignment procedure
and the periodic checkout procedures (Section 3.4.4).
To eliminate problem reflections:
to move the beams away
from the reflective surface(s), being careful to maintain
adequate safety (minimum) distance (see Figure 3-6).
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 LP
System. Perform the trip test, as described in Section 3.4.4, 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 bodily injury or death.
At the midpoint of the defined area, a test piece (represented by the
darker circle) with the specified system resolution does not cause
a blocked condition, due to an optical short circuit. Zone indicator
LEDs are ON Green and the OSSDs are ON.
•Otherwise, 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) in the safety (minimum) distance formula
(see Figure 3-7 and Section 3.1.1); 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 to verify that the changes eliminated
the problem. If the workpiece is especially reflective and
comes close to the defined area, perform the trip test with the
workpiece in place.

See the specific mirror data sheet or the Banner Safety Catalog for further information.
WARNING . . . Avoid Retroreflective
Installation
Do not install emitters and receivers in “retroreflective” mode,
with less than a 45° angle of incidence, as shown in Figure 3-8.
Sensing could be unreliable in this configuration; serious
bodily injury or death could result.
Mirrors are not allowed for applications that would allow
personnel undetected access into the safeguarded area.
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 3-8).
If placed at a sharper angle, as shown in the example, an
object in the light screen may deflect beam(s) to the receiver,
preventing the object from being detected (i.e., “false proxing”).
Angles greater than 120° result in difficult alignment and
possible optical short circuits.
Emitter
Emitter
Mirror
Mirror
Whenever two or more EZ-SCREEN LP emitter and receiver
pairs are adjacent to one another, optical crosstalk may
potentially take place between systems. To minimize optical
crosstalk, alternate the positions of emitters and receivers, (see
Figure 3-9a), or alternate scan codes.
When three or more sensor pairs are installed in the same plane
(as shown for two pairs in Figure 3-9), 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
“see” an emitter set to another code (see Section 4.2).
WARNING . . . Scan Code
In situations where multiple systems are mounted closely
together, or where a secondary emitter is in view (within ±5°),
within range of an adjacent receiver; the adjacent systems must be
configured for different Scan Codes (i.e., 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 will be discovered by performing the trip test
(see Section 3.4.3).
WARNING . . . Multiple Pairs of Sensors
Do not connect multiple pairs of sensors to one Interface
Module (e.g., IM-T-9A/-11A) or otherwise parallel OSSD outputs.
Connection of multiple OSSD safety outputs to a single device
can result in serious bodily injury or death, and is prohibited.

3.2.2 Mounting the Reset Switch
Mount the reset switch in a location that complies with the warning
in Section 3.1.3. See Figures 3-23 through 3-26 for electrical
connection.
3.2.3 Routing Cables
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 safety-related 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 Section 2.3 for selection of Bannersupplied cables.
NOTE:Themachineinterfacecablemustconnecttothesensor
end adjacent to the indicators, in order for the system to
operate properly.
EZ-SCREEN LP 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 or Latch condition; in extreme cases, a Lockout is possible.
1. Slide RD connector
firmly into housing’s
RD port
2. Tighten Phillips screws at base
of connector to lock into place
Figure 3-12. RD cordset installation
Emitter and receiver wiring is low voltage; routing the sensor
wires alongside power wires, motor/servo wires, or other highvoltage wiring may inject noise into the EZ-SCREEN LP system.
It is good wiring practice (and 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
Overview and Alignment
3.3 Initial Electrical Connections
Lockout/tagout procedures may be required (refer to OSHA
29CFR1910.147, ANSI Z244-1, 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 earth ground (green/yellow
wire, see Figures 3-23 through 3-26). Do not operate the
EZ-SCREEN LP System without an earth ground connection.
See the warning at right.
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 via RD or pigtail QD
connections.
Emitter Cordset
EZ-SCREEN LP emitters use an 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 (see
Figure 3-22), 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
Do not connect any wires to the machine control circuits
(i.e., OSSD outputs) at this time. For the initial power-up and
checkout, NO EDM must be configured. Locate the orange and
orange/black wires (pins 2 and 3) and temporarily connect the
ends of the wires to each other (but not to the machine at this
time). Take precautions to prevent the wires from shorting to
ground or to other sources of energy (e.g., terminate with the
included wire-nut). Final EDM wiring must be completed later.
If used, connect the external reset switch to the reset wire
(violet) on the receiver cable and to 24V dc (see Figures 3-24
and 3-26). See warning in Section 3.1.3 about the physical
location of the reset switch. The reset switch must be a normally
open switch that is held closed for approximately 1/4 second,
but no longer than 2 seconds, and then re-opened to accomplish
the reset. The switch must be capable of switching 10 to 30V dc
at 30 mA.
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 LP System than
are described in Sections 3.3 through 3.5.5 of this manual.
Connection of other wiring or equipment to the EZ-SCREEN LP
System could result in serious bodily injury or death.

Component #1

(Receiver)
Figure 3-15. Corner mirror alignment
Reduced resolution allows objects of a certain maximum size
to interrupt the defined area without causing a Trip condition
(i.e., the OSSDs turn OFF). Use Reduced Resolution only
when necessary. In reduced resolution applications, the safety
(minimum) distance always increases due to the larger depth
penetration factor (Dpf). In either case, see Section 3.1.1 to
determine separation distance.
With 2-beam reduced resolution enabled, any two consecutive
beams (except for the sync beam), can be blocked without
causing a stop condition. Thus, multiple “holes” are created in
which 14 mm systems will detect a 34 mm object and ignore a
16 mm object. Similarily, 25 mm sensors will detect a 65 mm
object and ignore a 36 mm object. See Figure 4-1 for DIP-switch
configuration. During operation, the Status indicator flashes
Green when reduced resolution is enabled.

Optical Alignment Procedure with Mirrors
EZ-SCREEN LP sensors may be used with one or more corner
mirrors for guarding more than one side of an area. The models
MSM... and SSM-... rear-surface glass mirrors are rated at 85%
efficiency. Thus, excess gain and sensing range are reduced
when using mirrors; see Section 3.1.7.
In addition to the standard optical alignment procedure for these
applications(seeFigures3-15and3-16),alsoverify:
•Thattheemitter,receiver,andallmirrorsarelevelandplumb,
•Themiddleofthedefinedareaandthecenterpointofthe
mirrors are approximately the same distance from a common
reference point, such as the same height above a level floor.
Ensure that 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.
WARNING . . . Use of Reduced Resolution
and Fixed Blanking
Use Reduced Resolution and 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
Section 3.1.1).
3.4.3 Fixed Blanking
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 LP sensor pair
may be “blanked out,” with a minimum of one beam between
two blanked areas. Any beam other than the sync beam may
be blanked. All beams of a fixed blanked area must remain
blocked during operation in order for the OSSDs to stay ON.
See Section 7.10 for instructions on remote fixed blanking
configuration and programming (cascadeable models only).

3.4.4 Trip Test
After optimizing the optical alignment and configuring fixed
blanking and reduced resolution (if applicable), perform the
trip test to verify the detection capability of the EZ-SCREEN
LP. This test will also verify correct sensor orientation (Section
3.1.5), identify optical short circuits (Section 3.1.6), and verify
the expected resolution for applications using reduced resolution
(Section 3.4.2). After the installation passes the trip test, the
safety outputs may be connected and the commissioning
checkout may be performed (initial installations only).

4. During each pass, while the test piece is interrupting the
defined area, at least one Zone indicator must be Red. The
Red Zone indicator must change with the position of the
test piece within the defined area.
•Trip Output Operation: The Status indicator must turn Red
and remain Red for as long as the test piece remains in the
defined area. If not, the installation has failed the trip test.
•Latch Output Operation: The Status indicator must turn
Red and remain Red. The Yellow Reset indicator must
remain ON steady. If the Reset indicator begins to flash at
any time while the test piece is interrupting the defined area,
the installation has failed the trip test.
If all Zone 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, reflective surfaces and unguarded areas created
due to the use of Blanking. Do not continue until the situation is
corrected.

WARNING . . . If Trip Test Indicates a
Problem
If the EZ-SCREEN LP System does not respond properly to the
trip test, do not attempt to use the System.
If this occurs, the EZ-SCREEN LP 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.
When the test piece is removed from the defined area, in trip
output operation, the Status indicator must turn ON Green (or
flash Green, if reduced resolution is enabled). In latch output
operation, the Status indicator will remain Red until a manual
reset is performed (the Yellow Reset indicator will be flashing).
If mirrors are used in the application: Test the defined area
on each leg of the sensing path (e.g. emitter to mirror, between
mirror and receiver, see Figure 3-18).
If the EZ-SCREEN LP System passes all three checks during
the trip test, go on to Section 3.5.
WARNING . . . Interfacing of Both OSSDs
Both of the 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) (e.g., PLC, PES, 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.
WARNING . . . OSSD Interfacing
To ensure proper operation, the EZ-SCREEN LP OSSD output
parameters and machine input parameters must be considered
when interfacing the EZ-SCREEN LP solid-state 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 could result in serious bodily injury or death.
WARNING . . . Shock Hazard
Always disconnect all power from the EZ-SCREEN LP System
and the guarded machine before making any connections or
replacing any component. Use extreme caution to avoid electrical
shock at all times.

EZ-SCREEN LP
Instruction Manual
Installation
Overview and Alignment
3.5.1 OSSD Output Connections
Both the output signal switching device (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 machine primary control element(s) (MPCE), resulting in a
non-hazardous condition.
Final switching devices (FSDs) typically accomplish this when
the OSSDs go to an OFF state. See Figure 3-24.
Refer to the output specifications in Section 2.7 and the
warnings on page 35 before making OSSD output connections
and interfacing the EZ-SCREEN LP to the machine.
3.5.2 FSD Interfacing Connections
Final switching devices (FSDs) can take many forms, although
the most common are forced-guided, mechanically linked relays
or an interface module. 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 LP. FSDs can also be used to
control an additional number of hazards by creating multiple
safety stop circuits.
Safety Stop (Protective Stop) Circuits
A 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 safety stop circuit typically
comprises a minimum of two normally open (N.O.) contacts from
forced-guided, mechanically linked relays, which are monitored
(via 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, safety stop
circuits are either single-channel, which is a series connection of
at least two N.O. contacts; or dual-channel, which is a separate
connection of two N.O. 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 will
arrest the hazard and prevent the next cycle from occurring).
See Figure 3-24.
The interfacing of the safety stop circuits must be accomplished
so that the safety function can not be suspended, overridden,
or defeated, unless accomplished in a manner at the same or
greater degree of safety as the machine’s safety related control
system that includes the EZ-SCREEN LP.
The normally open safety outputs from an interface module
provide a series connection of redundant contacts that form
safety stop circuits for use in either single-channel or dualchannel control. (See Figure 3-26.)
Dual-Channel Control
Dual-channel control provides the ability to electrically extend
the safe switching point beyond the FSD contacts. With proper
monitoring (i.e., EDM), 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
the loss of the switching ability of one of the FSD outputs. Such
failures could lead to the 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
increase, 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 the 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 can not
be achieved, then dual-channel control should be used.
Methods to exclude the possibility of these failures include, but
arenotlimitedto:
•Physicallyseparatinginterconnectingcontrolwiresfromeach
other and from secondary sources of power.
•Routinginterconnectingcontrolwiresinseparateconduit,runs,
or channels.
•Locatingallelements(modules,switches,anddevicesunder
control) within one control panel, adjacent to each other, and
directly connected with short wires.
•Properlyinstallingmulti-conductorcablingandmultiplewires
through strain relief fittings. (Over-tightening of a strain-relief
can cause short-circuits at that point.)
•Usingpositive-openingordirect-drivecomponents,installed
and mounted in a positive mode.

3.5.3 Machine Primary Control Elements and EDM Inputs
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 IEC61496-1). 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 (i.e., diverse redundant), but the
stop time performance of the machine (Ts, used to calculate the
safety distance, see Section 3.1.1) must take into account the
slower of the two channels. Refer to Figure 3-26 or consult the
machine manufacturer for additional information.
To ensure that an accumulation of failures does not compromise
the redundant control scheme (i.e., cause a failure to danger)
a method to verify the normal functioning of MPCEs or
other control devices is required. EZ-SCREEN LP provides
aconvenientmethodforthisverification:externaldevice
monitoring (EDM).
For the EZ-SCREEN LP external device monitoring to function
properly, each device must include a normally closed (N.C.),
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 (e.g., contacts that welded
closed or stuck ON).
It is strongly recommended that a normally closed, forced-guided
monitoring contact of each FSD and MPCE be connected to
EDM inputs (see Figures 3-24 and 3-26). 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 (ISO13849-1).
If monitoring contacts are not available or do not meet the
design requirement of being forced-guided (mechanically linked),
itisrecommendedto:
•Replacethedevicessothattheyarecapableofbeing
monitored,
or
•IncorporatetheEDMfunctionintothecircuitasclosetothe
MPCE as possible (e.g., monitor the FSDs),
and
•Employuseofwell-tried,tested,androbustcomponents,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.
WARNING . . . EDM Monitoring
If system is configured for “No Monitoring,” it is the user’s
responsibility to ensure that this does not create a hazardous
situation.
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.
External Device Monitoring
EZ-SCREENLPprovidesthreepossibleEDMconfigurations:
1-channel monitoring, 2-channel monitoring, and no monitoring.
Their functions are described below. The most common form
of EDM is 1-channel monitoring; its primary advantages are
simplicity of wiring and the ability to use the Auxiliary output.
The installation must prevent short circuits across the N.C.
monitoring contacts and to secondary sources of power.
Two-channel monitoring has the ability to detect additional
failures, such as short circuits, and should be used when those
failures can not be designed out or reasonably be excluded.
Two-channel monitoring is also the default setting and has the
advantage of additional diagnostic capability that can identify
which specific element that has slowed or failed.

Instruction Manual
Installation
Overview and Alignment
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 Figures 3-24 and 3-26). Pins 2 and 3 of the receiver
connector provide connection for the external device monitoring
input. External device monitoring (EDM) must be wired in
one of three configurations described below and this wiring
configuration must agree with the receiver’s EDM DIP switch
settings (see Section 4.2).
One-Channel Monitoring: This is a series connection of closed
monitor contacts that are forced-guided (mechanically linked)
from each device controlled by the EZ-SCREEN LP. The monitor
contacts must be closed before the EZ-SCREEN LP can be
reset and the OSSDs can turn ON. After a reset is executed
and 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.
See Figure 3-19.
Refer to Figure 3-26 for 1-channel EDM hookup. Connect the
monitor contacts between +24V dc and EDM1 (pin 3). Leave
EDM2 (pin 2) open (no connection), unless using the Auxiliary
Output feature (Section 3.5.5). Set the configuration DIP switch
to the 1-channel EDM position, per Section 4.2.
Two-Channel Monitoring: This is an independent connection
of closed monitor contacts that are forced-guided (mechanically
linked) from each device controlled by the EZ-SCREEN LP. The
monitor contacts must be closed before the EZ-SCREEN LP can
be reset and the OSSDs can turn ON. Regardless of the state of
the OSSDs, the monitor contacts may change state (either both
open, or both closed). If the monitor contacts remain in opposite
states for more than 250 milliseconds, a lockout will occur.
Refer to Figures 3-24 or 3-26 for 2-channel EDM hookup.
Connect the monitor contacts as shown between +24V dc and
EDM1 (pin 3) and between +24V dc and EDM2 (pin 2). Set the
configuration DIP switch to the 2-channel EDM position, per
Section 4.2.
No Monitoring: Use this configuration initially, in order to
perform the initial checkout; see Section 3.6. 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.
Refer to Figure 3-25 for “no monitoring” hookup. To configure
the EZ-SCREEN LP for no monitoring, connect or jumper EDM1
(pin 3) to EDM2 (pin 2) using the supplied wire-nut. Set the
configuration DIP switch to the 2-channel EDM position, per
Section 4.2.
An alternate method to configure no monitoring is to set the
configuration DIP switch to the 1-channel EDM position, per
Section 4.2, and connect EDM1 (pin 3) to +24V dc. This method
allows the use of the auxiliary output (see Section 3.5.5) in
applications that do not require the EDM function.
3.5.4 Remote Test Input
An emitter connection is provided (Test) for the connection of an
external remote test switch (typically a normally open contact
held closed). Opening this switch “turns OFF” the emitter,
simulating an interruption of the light beams; all OSSD outputs
will turn OFF. This input is used in conjunction with the emitter
Test/Reset DIP switch. See Sections 2.7.2, 4.2, and Figure 3-23.
3.5.5 Auxiliary (OSSD Follow/Fault) Output
EZ-SCREEN LP receivers have an auxiliary status output that
provides a PNP current-sourcing output (250 mA max.) that
mirrors the state of the OSSDs or indicates a lockout (ON =
Fault). The output is on pin 2 (orange/black wire) when the
EDM configuration DIP switch is set to the 1-channel monitoring
position, per Section 4.2. See the 1-channel EDM circuit on
Figure 3-26 for hookup information.
To use the auxiliary output in an application configured for no
monitoring, set the configuration DIP switch to the 1-channel
monitoring position, per Section 4.2, and connect EDM1 (pin 3)
to +24V dc (see Section 3.5.3).
The emitter also has a Fault output that can be enabled to
indicate the emitter lockout status (see Section 4.2 Fault).
3.6 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 LP is ready for testing
in combination with the guarded machine.
The operation of the EZ-SCREEN LP with the guarded machine
must be verified before the combined EZ-SCREEN LP and
machine may be put into service. To do this, a Qualified Person
must perform the Commissioning Checkout Procedure
described in Section 6.2.
3.7 Sensor “Swapability” and Emitter Hookup
Figure 3-22 illustrates a hookup option that provides sensor
interchangeability (or “swapability”) – the ability to install either
sensor at either QD connection. This allows the emitter and
receiver positions to be easily swapped, similar to a popular
®
feature of Banner MACHINE-GUARD™, MINI-SCREEN and
®
MICRO-SCREEN safety light screens, providing advantages
during installation, wiring, and troubleshooting.
To use this option, connect all emitter wires in parallel (colorfor-color) to the receiver cable via individual wires or the CSB..
splitter cordset.

4.2 System Configuration Settings
If not previously configured, System settings are made on the
configuration panels located on each sensor, behind the access
door. The access door is opened by loosening the factoryinstalled screw. See Figure 4-1.
The receiver has redundant Trip/Latch and Reduced Resolution
DIP switches, which must be set identically (see Section 4.2).
Failure to do so will cause a Lockout condition when power is
applied. If the corresponding pairs of DIP switches are not
set identically, the EZ-SCREEN LP will not operate.
Power to the EZ-SCREEN LP receiver should be OFF when
changing DIP switch settings (other than Scan Code) or a
Lockout will occur.
After configuration settings are verified/set, fully close the
access door and tighten the screw to maintain the sensor IP
rating.

EZ-SCREEN LP
Instruction Manual
Scan code is used to allow operation of multiple pairs of
emitters and receivers in close proximity (see Sections 3.1.8 and
1.4.4). Scan code may be set to 1 or 2, via DIP switch (see Table
4-1). The scan code setting for each emitter must agree with its
corresponding receiver. Scan code settings may be changed
while in Run mode without causing a Lockout.
Trip or latch output operation is selected on two DIP switches
in the receiver configuration port; see Figure 4-1. Both switches
must be set to the same setting. If they have different settings,
an error code will be displayed.
If the switches are set for trip output (T), the EZ-SCREEN LP will
auto-reset after a blocked condition. If the switches are set for
latch output (L), it will require a manual reset.
External Device Monitoring (EDM): EDM mode is selected
via a 2-position DIP switch on the receiver; see Figure 4-1. For
1-channel monitoring, set the EDM DIP switch to the 1-channel
EDM position. For 2-channel monitoring or no monitoring, set the
switch to the 2-channel EDM position (see Section 3.5.3).
Auxiliary Output: Determines whether the aux. output follows
the state of the OSSDs (ON = Green Status LED) or if the
sensor is in a lockout (ON = Fault).When 2-channel monitoring
(EDM) is selected, these aux. output options are not available
and this DIP switch setting has no effect (see Section 1.4.3).
Reduced Resolution: Enables or disables two-beam reduced
resolution (see Section 3.4.2), and is selected on two DIP
switches that must be set to the same setting.
NOTE:Enablingreducedresolutionwillaffecttheminimum
safety distance (see Section 3.1.1).
Inverted Display: Inverts the 7-segment display for right-reading
when sensors are mounted with the indicator end facing up. DIP
switch position OFF results in standard orientation.
Test/Reset: This emitter-only function is used to configure the
violet wire (pin 8) for either a Reset function (similar to the
receiver), or for a Test function which, when activated, simulates
a blocked condition for receiver testing purposes. See emitter
hookups, Figure 3-23.
NOTE:TheemitterTestfunctioncannotbeusedinacolor-forcolor (“swapable”) hookup.
Fault (Emitter): This emitter-only function is used to determine
whether the emitter Fault signal is active (+24V) when the
emitter locks out. Options are ON or OFF. If the color-for-color
(“swapable”) hookup is used and the receiver is configured for
2-channel EDM or OSSD follow, set this switch to OFF; if the
system is configured for OR fault function, set this switch to ON
(see Figure 3-22).
System Overview
Operation
4.3 Reset Procedures
Resetting the System
System resets are typically performed using an external reset
switch. This switch must be located as discussed in Section
3.1.3.
If supervisory control of the reset switch is required, a key
switch may be used, with the key kept in the possession of a
Designated or Qualified Person. Using a key switch will also
provide some level of personal control, since the key may
be removed from the switch. This will hinder a reset while
the key is under the control of an individual, but must not be
relied upon solely to guard against accidental or unauthorized
reset. Spare keys in the possession of others or additional
personnel entering the safeguarded area unnoticed may create
a hazardous situation.
Emitter and Receiver Resets
The EZ-SCREEN LP receiver and emitter each have a Reset
input, pin 8 (Violet wire), that provides for a manual reset input
signal.
The receiver requires a manual reset to clear a Latch condition
and resume operation following a stop command. Internal
Lockout conditions also require a manual reset to return either
the emitter or the receiver to Run mode after the failure has
been corrected. Emitter resets are needed only in the unlikely
event that a Lockout occurs.
Receiver manual resets are required in the following
situations:
•Trip output operation – only after a Lockout (see Section 5
for causes).
•Latch output operation – at power-up, after each Latch
condition occurs, and after a Lockout.
Reset Routine
To reset the emitter and/or receiver, close the reset switch
for 1/4 to 2 seconds, then open it. (If reset switch model
MGA-KS0-1, listed in Section 2, is used, turn the key 1/4
turn clockwise to close; turn counterclockwise, back to its
original position, to open.) An alternate method to reset either
component is to power the sensor down, then power it up.
NOTE:Closingtheresetswitchtoolongwillcausethesensor
to ignore the reset request; the switch must be closed
from 1/4 second to 2 seconds, but no longer.

Status Indicators for Cascaded Applications
When multiple light screens are cascaded, some unique
indications may occur, as indicated in Figure 4-7 and table 4-2.
When a receiver’s CSSI input is in a Stop condition (because
of a blocked light screen further upstream in the cascade, or
because of a Stop signal from an E-stop button, for example),
the display on the downstream receivers, including the master
receiver, will be bracketed by a pair of vertical “goalposts.” See

EZ-SCREEN LP
Instruction Manual
4.5 Normal Operation
System Power-Up
The EZ-SCREEN LP will power up in one of two ways,
depending on the trip/latch output configuration. If it is set for
trip output, it will power up and reset automatically; if it is set
for latch output, it will require a manual reset procedure after
power-up and sensor alignment.
Trip Output Power-Up: When power is applied, each sensor
conducts self-tests to detect critical internal faults, determine
configuration settings, and prepare the EZ-SCREEN LP for
operation. (If either sensor detects a critical fault, scanning
ceases, the receiver outputs remain OFF and diagnostic
information is displayed on the sensor’s 7-segment display.)
If no faults are detected, the EZ-SCREEN LP 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.
Latch Output Power-Up: When power is applied, each sensor
conducts self-tests to detect critical internal faults, determine
configuration settings, and prepare for operation. (If either
sensor detects a critical fault, scanning ceases, the receiver
outputs remain OFF and diagnostic information is displayed on
the sensor’s 7-segment display.) If no faults are detected, the
EZ-SCREEN LP 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
begins scanning to determine the blocked or clear status of each
beam. When all beams are aligned, the Yellow Reset indicator
double-flashes to indicate the EZ-SCREEN LP is waiting for a
manual reset. After a valid manual reset, the EZ-SCREEN LP
enters Run mode and continues scanning.
System Overview
Operation
During Run Mode
Trip Output Configuration: If any beams become blocked
while the EZ-SCREEN LP is running with trip output selected,
the receiver outputs turn OFF within the stated EZ-SCREEN
LP response time (see Specifications). If all the beams then
become clear, the receiver outputs come back ON. No resets
of any kind are needed. All required machine control resets are
provided by the machine control circuit.
Latch Output Configuration: If any beams become blocked
while the EZ-SCREEN LP is running with latch output selected,
the receiver outputs turn OFF within the stated EZ-SCREEN
LP response time (see Specifications). If all the beams then
become clear, the receiver Zone indicators will all be Green and
the Reset indicator single-flashes, indicating the EZ-SCREEN
LP is waiting for a manual latch reset. In latch output operation,
the outputs come back ON only when all beams are clear and
after a manual reset. The EZ-SCREEN LP will wait for a manual
reset; when a valid reset signal is received and all beams
remain clear, the receiver outputs turn ON.
Internal Faults (Lockouts): If either sensor detects a critical
fault, scanning ceases, the receiver outputs turn OFF and
diagnostic information is displayed on the sensor’s 7-segment
display. See Section 5 for resolution of error/fault conditions.
4.6 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 (see
Section 6.3 and the Daily Checkout Card for the procedure).
Semi-annually, the EZ-SCREEN LP and its interface to the
guarded machine should be thoroughly checked out; this
checkout must be performed by a Qualified Person (see Section
6.4). 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 LP or changes to the
machine), the Commissioning Checkout should be performed
(see Section 6.2).
WARNING . . . Verify Proper Operation
It is the user’s responsibility to verify proper operation, on a regular
basis, as instructed in Section 6. Failure to correct such problems
can result in serious bodily injury or death.

Overview
5. Troubleshooting and Maintenance
5.1 Troubleshooting Lockout Conditions
Evaluate status indicators per Section 4.4. See Section 5.2 for
Test mode indication.
A Lockout condition causes all of the EZ-SCREEN LP’s 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
Sections 5.1.1 and 5.1.2 or the Diagnostic Error Code label
supplied in the documentation pack).

EZ-SCREEN LP
Instruction Manual
Troubleshooting
and Maintenance
Overview
5.3 Electrical and Optical Noise
5.4 Servicing and Maintenance
The EZ-SCREEN LP 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 or Latch condition. In very
extreme electrical noise cases, a Lockout is possible. In order
to minimize the effects of transitory noise, the EZ-SCREEN LP
will respond to noise only if the noise is detected on multiple
consecutive scans.
Cleaning
IfrandomnuisanceTripsoccur,checkthefollowing:
• Poorconnectionbetweenthesensorandearthground;
• Opticalinterferencefromadjacentlightscreensorother
photoelectrics; or
• Sensorinputoroutputwiresroutedtoocloseto“noisy”wiring.
EZ-SCREEN LP components are designed for reliability. Do
not open the emitter or receiver housings, other than the
configuration access door. (Following configuration, close the
access door and tighten the screw to maintain IP65 status.)
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 LP wiring is low voltage; running these wires
alongside power wires, motor/servo wires, or other high-voltage
wiring, can inject noise into the System. It is good wiring practice
(and may be required by code) to isolate EZ-SCREEN LP wires
from high-voltage wires.
The Banner model BT-1 beam tracker (see Section 2.4) is a
good tool for detecting electrical noise (transient spikes and
surges). Cover the lens of the beam tracker with electrical tape
to block optical light from the receiver lens. Press the “RCV”
button, and position the beam tracker on the wires going to the
EZ-SCREEN LP or any other nearby wires. Noise caused by
the switching of inductive loads will cause the beam tracker’s
indicator to light; address the noise problem by installing proper
transient suppression across the load.
EZ-SCREEN LP standard emitters and receivers are
constructed of aluminum with a yellow painted finish and are
rated IP65. 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.
Warranty Service
Sensors contain no field-replaceable components. If repair
is necessary, do not attempt to repair an emitter or receiver
yourself; return the unit to the factory, as described below.
1. Contact a Banner Factory Application Engineer at the
addressornumberslistedbeloworonthebackpage:
Banner Engineering Corp.,
9714 Tenth Avenue North
Minneapolis, MN 55441
They will attempt to troubleshoot the System from
your description of the problem. If they conclude that a
component is defective, they will issue a return merchandise
authorization (RMA) number for your paperwork, and give
you the proper shipping address.
2. Pack the component(s) carefully. Damage which occurs
during return shipping is not covered by warranty.
Checking for sources of optical noise: Turn off the
EZ-SCREEN LP emitter, completely block its beams, or open the
Test input, then use a Banner BT-1 beam tracker to check for
light at the receiver. Press the “RCV” button and move the beam
tracker along the full length of the receiver’s sensing window.
If the beam tracker’s indicator lights, check for light from other
sources (other safety light screens, grids, or points, or standard
photoelectric sensors) by “tracking down” the emitted light from
them.

Checkout Procedures
Overview
6. Checkout Procedures
Study each procedure in its entirety, to understand each step
thoroughly before beginning. Refer all questions to a Banner
applications engineer at the address or numbers listed on the
cover of this manual. Checkouts must be performed as detailed
in Section 6.1 below and results should be recorded and kept
in the appropriate place (e.g., near the machine, and/or in a
technical file).
6.1 Schedule of Checkouts
Trip Test: The procedure for the EZ-SCREEN LP trip test is
described in Section 3.4.4. This procedure must be performed
at installation, and at any time the EZ-SCREEN LP, the guarded
machine, or any part of the application is installed or altered.
The procedure must be performed by a Qualified Person.
Commissioning Checkout: The procedure described in Section
6.2 must be performed at installation or whenever changes
are made to the System (either a new configuration of the
EZ-SCREEN LP or changes to the machine). The procedure
must be performed by a Qualified Person.
Shift/Daily Checkout: The procedure for “daily” checkout of the
EZ-SCREEN LP is described on the supplied Daily Checkout
card (Banner p/n 140045 for SLP.. stand-alone models, P/N
140046 for SLPC.. cascadeable models). Daily Checkout is to
be performed at each shift change or machine setup change,
whenever the System is powered up — at least daily. The
procedure is listed on the Daily Checkout card and may be
performed by a Designated Person or a Qualified Person.
Semi-Annual Checkout: The procedure for initial checkout
of the EZ-SCREEN LP System is to be performed every six
months, following installation. The procedure is listed on the
Semi-Annual Checkout card (Banner P/N 140047) and must be
performed by a Qualified Person.
6.2 Commissioning Checkout
Perform this checkout procedure as part of the EZ-SCREEN
LP installation (after it has been interfaced to the guarded
machine as described in Section 3.5), or whenever changes
are made to the System (either a new configuration of the
EZ-SCREEN LP or changes to the machine). A Qualified
Person (as defined in Section 4.1) must perform the procedure;
checkout results should be recorded and kept on or near the
guarded machine as required by applicable standards.
TopreparetheSystemforthischeckout:
1. Examine the guarded machine to verify that it is of a type and
design compatible with the EZ-SCREEN LP. See Section 1.2
for a list of misapplications.
2. Verify that the EZ-SCREEN LP is configured for the intended
application (see Section 4.2).
3. Verify that the minimum safety distance from the closest
danger point of the guarded machine to the defined area is
not less than the calculated distance, per Section 3.1.1 of this
manual.
4.Verifythat:
•Accesstoanydangerouspartsoftheguardedmachine
is not possible from any direction not protected by
the EZ-SCREEN LP, hard guarding, or supplemental
safeguarding, and
•Itisnotpossibleforapersontostandbetweenthedefined
area and the dangerous parts of the machine, or
•Supplementalsafeguardingandhardguarding,asdescribed
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 LP (see Sections
3.1.2 and 3.1.4).
5. 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 (see Section 3.1.3).
6. Examine the electrical wiring connections between the
EZ-SCREEN LP’s FSD outputs and the guarded machine’s
control elements to verify that the wiring meets the
requirements stated in Section 3.5.
7. Inspect the area near the defined area (including work pieces
and the guarded machine) for reflective surfaces (see Section
3.1.6). Remove the reflective surfaces if possible by relocating
them, painting, masking or roughening them. Remaining
problem reflections will become apparent during the trip test
in step 11.
8. Apply power to the EZ-SCREEN LP. Verify that power to the
guarded machine is OFF. Remove all obstructions from the
defined area. If the EZ-SCREEN LP is configured for latch
output, the Yellow Status indicator will double-flash; perform a
manual reset (close the reset switch for 1/4 to 2 seconds, then
open it).

Alignment procedure in Section 3.4. If the System is in a
Latch condition, perform a manual reset.
11. Once the Green and Yellow Status indicators are ON,
perform the trip test (described in Section 3.4.4) 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 LP System passes the trip
test. 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 could result in serious
bodily injury or death.
12. Apply power to the guarded machine and verify that the
machine does not start up. Interrupt (block) the defined area
with the appropriate supplied test piece (see table in Section
3.4.4) and verify that it is not possible for the guarded
machine to be put into motion while any beam is blocked.
13. 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 should come to a stop
with no apparent delay.
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.
14. Remove electrical power to the EZ-SCREEN LP. Both OSSD
outputs should immediately turn OFF, and the machine
should not be capable of starting until power is re-applied to
the EZ-SCREEN LP.
15. 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. (Banner’s applications
engineers can recommend a suitable instrument.)
Do not continue operation until the entire checkout
procedure is complete and all problems are corrected.
WARNING . . . Do Not Use Machine Until
System Is Working Properly
If any of these checks cannot be verified, do not attempt to
use the EZ-SCREEN LP/guarded machine until the defect or
problem has been corrected (see Section 5).
Attempts to use the guarded machine under such conditions
could result in serious bodily injury or death.
6.3 Shift/Daily Checkout
Perform the procedure contained on the Daily Checkout
card at every shift change, power-up and machine setup change. During continuous machine run periods, this
checkout should be performed at intervals not to exceed 24
hours.
A Designated Person or Qualified Person (as defined in the
Glossary) must perform the procedure. A copy of checkout
results should be recorded and kept in the appropriate place
(e.g., near or on the machine, in the machine’s technical file).
Refer to the procedure detailed on the Daily Checkout card
(Banner p/n 140045 for SLP.. stand-alone models, P/N 140046
for SLPC.. cascadeable models) in the lit packet included with

Cascadeable EZ-SCREEN
Overview
7. Cascadeable EZ-SCREEN LP
7.1 Overview of Cascading
EZ-SCREEN LP emitters and receivers are also 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 7-1. The cascaded sensor pairs can be any length,
any number of beams, or have different resolutions (i.e., 14 mm
and 25 mm), as long as each emitter matches its own receiver.
NOTE:EZ-SCREENSLP.. (stand-alone) or 8-pin SLSC..
models can be used as the end sensor pair. EZ-SCREEN
Grid/Point and PICO-GUARD components can not 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 Section 2.3. All receivers in a cascade activate the
samesetofOSSDoutputs:theOSSDsofthemasterreceiver.
NOTE: In a cascaded system, all receivers are connected
together, and all emitters are connected together.
7.1.1 System Components and Specifications
A multiple-light screen cascaded EZ-SCREEN LP 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
IP65 rating.) Additional cordsets may be used to enable QD
connections; see Section 2.3.
The terminator plug (model LPA-TP-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 box or
an RDLP6G-4..D cordset interfaced with an E-stop or other hard
onta ts is in pla e see e tions

The following Cordset length charts are possible combinations
for each side of example cascaded systems. Model DELP-..E
cordsets (24 awg wire) used for calculations. Other lengths and
combinations are possible; please call factory for assistance.
As the machine interface Cordset lengthens, the voltage drop

4.6 m (15')
increases, which results in shorter possible interconnect Cordsets
to maintain supply voltage requirements at the cascaded sensor.
See Section 2 for Cordsets.Due to the large number of possible
combinations, the table in Figure 7-4 includes only applications
in which L2 = L4. A common installation example is one that
protects two areas of a machine (e.g., the front and back of a
power press) and uses four EZ-SCREEN LP pairs to create two
“L”-shaped sensing fields.

7.5 Response Time for Cascaded Light Screens
Response time is an important factor in determining a light
screen’s separation (safety) distance. For cascaded (or “daisychained”) EZ-SCREEN LP 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
calculatedeasily,intwoways:
•Individuallyforeachlightscreeninthecascade(safety
(minimum) distance is calculated for each light screen in the
cascade), or
•Basedontheworst-casetimefortheentirecascade(where
all light screens in the cascade have the same separation
distance).

Overview EZ-SCREEN
Individual Response Time and Safety (Minimum) Distance
When calculating individual safety (minimum) distance for each
emitter/receiver pair, the pair’s position in the cascade impacts
its response time, which then impacts its safety distance (see
safety distance formulas in Section 3.1.1). The “individual”
method results in the closest possible safety distance for each
light screen in the cascade, while ensuring that each sensor pair
is located at an adequate distance from the hazard.

17 ms Response
Response time depends on how far “downstream” the light
screen is from the machine control. Each light screen position in
the cascade, starting from the first light screen in the cascade,
increases the light screen’s response time by 2 ms.

15 ms Response
Figure 7-5 depicts a four-pair cascade. The 25 mm resolution,
550 mm EZ-SCREEN LP emitter/receiver pairs each begin with
a response time of 11 ms. The pair in position #1 (connected
directly to the machine control), maintains its 11 ms response
time. Response time for the second pair in the cascade circuit
increases by 2 ms, to 13 ms; for the third pair by 4 ms, to 15
ms, and for the fourth pair by 6 ms, to 17 ms. To calculate
response time (Tr) for individual placement of each emitter/
receiver pairinthecascadedsystemusetheformulas:
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

*Light screens of other lengths / resolutions will have different response times.
Overall Response Time and Safety (Minimum) Distance
The cascaded system’s Overall Response Time (Tr) is equal
to the response time of the individual sensor pair with the most
beams (i.e., the slowest individual response time), plus an adder
resulting from the number of systems in the cascade. Tr can be
foundbythefollowingformula:
Tr = Tr(max) + [(N-1) x 2 ms]
where:
Tr(max) is the response time of the slowest individual pair in the
cascade (i.e., the pair with the most beams; see Section 7.2).
N is the number of sensor pairs in the cascade.
Use this Tr value in the formula in Section 3.1.1 to determine
Overall Safety Distance (Ds). This will ensure that all sensor
pairs will be located at an adequate distance from the hazard,
no matter how the system is installed.
When contacts (e.g., an E-stop button) are connected to a
cascaded receiver (per Section 7.8), CSSI response time is
40 ms plus the 2 ms adder for each additional light screen,
similar to the defined area Tr.
Tr(CSSI) = 40 ms + [(N-1) x 2 ms]

When light screens of different lengths or different resolutions
(and therefore different response times) are used in one circuit,
their positions in the cascade may become a consideration.
For example, consider the light screen circuits depicted in
Figure 7-6. Each example contains three safety light screens,
one 1810 mm long (with a response time of 43.5 ms), and two
410 mm long (13.5 ms response each). Depending on their
placement in the cascade, the individual response time for the
same three light screens can vary.

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 greatest number of beams (worst case Tr), and use that
number as the overall response time. The 6 ms adder increases
safety distance a total of 10 mm (0.4") when using 1600 mm/s for
the hand speed constant K (see Section 3.1.1).

7.6 Cascaded Sensor Configuration Settings
Setting cascaded sensors for scan code, trip or latch output,
external device monitoring (EDM), reduced resolution, fixed
blanking and inverted display is identical to the procedure for
non-cascadeable emitters and receivers (see Section 4).
Scan codes for each emitter and receiver pair must match.
However, for cascaded installations, scan codes must alternate
on adjacent systems as described in Section 3.1.8 and Figure
3-10. See warning.
While the scan code, reduced resolution, fixed blanking, and
inverted display settings are independent for each cascaded
sensor pair, the trip/latch mode and EDM settings must be
determined by the first receiver in the cascade (closest to the
machine interface), which controls the OSSD outputs. All other
receivers in the cascade must be set for trip mode and
2-channel EDM (factory default settings).
The settings on the first receiver then determine trip or latch
mode and 1- or 2-channel EDM/aux. output, and this is the only
receiver that requires a reset following a latch condition.
WARNING . . . Scan Code
In situations where multiple systems are mounted closely
together, or where a secondary emitter is in view (within ±5°),
within range of an adjacent receiver; the adjacent systems must be
configured for different Scan Codes (i.e., 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 will be discovered by performing the trip test
(see Section 3.4.4).
7.6.1 Fixed Blanking
One or more areas within any cascaded EZ-SCREEN LP sensor
pair can be blanked out, just as with other EZ-SCREEN LP light
screens. Blanking for each sensor pair within a cascade, if
required, must be programmed separately. See Section 3.4.3
for more information and programming procedure.
For cascadeable models only: a standalone receiver or the
last receiver in a cascade may be configured remotely for fixed
blanking, using an EZA-RBK-1 remote key switch box or other
options as described in Section 7.10.

7.7 Configuration for Cascaded Operation
Each cascaded system must be configured, before it can be run
in a production environment.
Before configuration, install all emitters and receivers per
Sections 3 and 7. The last SLPCR-.. receiver must be
terminated either with a terminator plug, or with an EZARBK-1 remote key switch box, or by connecting two closed
mechanical contacts (see Sections 7.8 and 7.9).
Perform the following procedure on the first receiver only in
the cascade (closest to the machine interface). Other than scan
code, set all other receivers in the cascade to the factory default
positions.
1. From either normal operation or a power OFF condition, set
the first and fourth DIP switches (T/L and Red Res) both
to the left (Trip operation and Reduced Resolution enabled
positions). See Figure 7-7.
2. Set the second and third DIP switches (Red Res and T/L)
both to the right (Reduced Resolution OFF and Latch
operation positions).
3. The receiver should be in a lockout condition or power OFF.
4. If power is OFF: Apply power
Lockout condition: Perform a valid reset sequence (close
the reset switch for 0.25 to 2 seconds, then reopen).
5. Coming out of lockout or during startup, the DIP switch
configuration will be recognized as Cascaded Teach Mode,
indicatedbythefollowing:

SCAN or EDM switch positions).
3. Press the Reset button or cycle power.
4. Reconfigure DIP switches for normal operation.
5. Press the Reset button or cycle power.
NOTE: If the EDM wiring does not match the switch
position, an EDM error occurs and cascade
configuration will not be allowed.
Figure 7-7. DIP switch configuration to enable cascade installation
7.8 Emergency Stop Buttons and Devices
Cascadeable EZ-SCREEN LP 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.
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 Ohms.
NOTE:ThesimultaneitybetweenthetwoE-stopcontacts,on
opening and closing, is 3 seconds. If simultaneity is not
met on either opening or closing, the last receiver’s display
will flash “|-|”. If simultaneity is not met on opening, the
closed contact can be opened later (after more than 3
seconds), then both contacts must be closed again.
WARNING . . . Emergency Stop Functions
If Cascade Input is used for an Emergency Stop function, do not
mute or bypass the safety outputs (OSSDs) of the EZ-SCREEN LP.
ANSI/NFPA79 and IEC 60204-1 require that the Emergency Stop
function remain active at all times. Muting or bypassing the safety
outputs will render the Emergency Stop function ineffective.

Instruction Manual
Cascadeable EZ-SCREEN
Overview
E-Stop Switch Requirements (Positive-Opening)
As shown in Figure 7-8, 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
additionalrequirements:
•EmergencyStoppushbuttonsshallbelocatedateach
operator control station and at other operating stations where
emergency shutdown shall be required.
•StopandEmergencyStoppushbuttonsshallbecontinuously

NOTE:Someapplicationsmayhaveadditionalrequirements.
The user must comply with all relevant regulations.
E-Stop 1
E-Stop 2
E-Stop N
WARNING . . . Multiple E-Stop Switches
•WhenevertwoormoreE-stopswitchesareconnected
to the same EZ-SCREEN LP 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 LP
receiver input.
Never connect the contacts of multiple E-stop switches in
parallel to the EZ-SCREEN LP inputs; this defeats the switch
contact monitoring ability of the EZ-SCREEN LP light curtain,
and creates an unsafe condition which could result in
serious bodily injury or death.
•Also, when two or more E-stop switches are used, each
switch must be individually actuated (engaged), then
re-armed and the EZ-SCREEN LP light curtain reset (if using
latch mode). 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 returning the E-stop switch to its closed-contact
position (when arming the E-stop switch). When automatic reset is
used, an alternate means must be established to require a reset
routine, after the E-stop switch is armed. Allowing the machine
to restart as soon as the E-stop switch is armed creates an
unsafe condition which could result in serious injury or death.

EZ-SCREEN LP
Instruction Manual
Cascadeable
Overview EZ-SCREEN
7.9 Positive-Opening Safety Interlock Switches
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, it
is the responsibility of the user to safely install, operate, and
maintain each safety system and comply with all relevant laws
and regulations. Of the following applications, Figure 7-9 meets
or exceeds the requirements for OSHA/ANSI control reliability
and Safety Category 4, per ISO 13849-1.
WARNING . . . Unguarded Moving Parts
It must not be possible for personnel to reach any hazard point
through an opened guard (or any opening) before hazardous
machine motion has completely stopped.
Please reference OSHA CFR1910.217, ANSI B11 standards, or
other appropriate standards for information on determining safety
distances and safe opening sizes for your application (see Inside
back cover).
The safety switches and actuators used with the Cascade must
be designed and installed so that they cannot be easily defeated.
They must be mounted securely, so that their physical position
can not 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.
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 (see
Figure 7-9).
The contacts must be of “positive-opening” design, with one or
more normally closed contacts rated for safety. Positive-opening
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 (see the Banner Safety Catalog for examples).
In addition, the switches must be mounted in a “positive mode”
to move/disengage the actuator from its home position and open
the normally closed contact when the guard opens.
Interlock Guarding Requirements
Open
The following general requirements and considerations apply to
the installation of interlocked gates and guards for the purpose
of safeguarding. In addition, the user must refer to the relevant
regulations to be sure to comply with all necessary requirements.
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 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 (ANSI/RIA R15.06). 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.
NOTE: This application is considered
to meet or exceed requirements
for OSHA/ANSI control reliability
and Category 4 per ISO 13849-1.

its reset function. If the EZ-SCREEN LP does not reset, a switch
may have failed; that switch must be immediately replaced.
This check must be performed and all faults must be cleared, at
a minimum, during periodic checkouts. If the application can
not exclude these types of failures and such a failure could
result in serious injury or death, then the safety switches
must not be connected in series.

Overview EZ-SCREEN
7.10 Remote Fixed Blanking
As described in Sections 1.4.9 and 3.4.3, 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 LP sensor pair may be “blanked out,”
with a minimum of one beam between two blanked areas. The
first sensing beam (synchronization beam) at the display end of
sensor must remain clear (can not 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 LP cascade receiver as a stand-alone system
or as the end (slave) unit in a cascaded system. The remote
programming is only effective on that receiver. If fixed blanking
is required on other receivers in the cascade string, see Section
3.4.3 for DIP switch configuration information.
Programming Key Switch Location
The EZA-RBK-1 or an SPDT (Form C) switch is required to
perform the remote programming procedure, as shown in Figure

Overview
EZ-SCREEN LP
Instruction Manual
Glossary of Terms
The following terms are used often in this manual. Where
possible, this manual uses definitions from the U.S. and
international product performance standards that govern the
design of the Safety Controller. For more definitions, visit
Banner Engineering website.
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.
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 “Safety
Standards” on inside back cover.
Defined Area: The “screen of light” generated by a safety light
screen system, defined by the height and the safety (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.
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.
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 fixed blanking, Floating
Blanking, and Reduced Resolution.
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.
Brake: A mechanism for stopping, slowing, or preventing motion.
Cascade: Series connection (or “daisy-chaining”) of multiple
emitters and receivers.
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.
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.
Designated Person: An individual identified and designated
in writing, by the employer, as being appropriately trained and
qualified to perform a specified checkout procedure. (See
Qualified Person.)
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)mayinclude,butarenotlimitedto:MPCEs,captive
contact relays/contactors, and safety modules.
Failure to Danger: A failure which delays or prevents a machine
safety system from arresting dangerous machine motion, thereby
increasing risk to personnel.
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.
Fixed Blanking: A programming feature that allows a safety light
screen system to ignore objects (such as brackets or fixtures)
which will always be present at a specific location within the
defined area. The presence of these objects will not cause the
system’s safety outputs (e.g., Final Switching Devices) to trip or
latch. If any fixed objects are moved within or removed from the
defined area, a Lockout condition results.
Floating Blanking: See Reduced Resolution.

EZ-SCREEN LP
Instruction Manual
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.
Guarded Machine: The machine whose point of operation is
guarded by the safety system.
Hard 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 openings is determined by the applicable standard, such
as Table O-10 of OSHA 29CFR1910.217, also called a “fixed
barrier guard.”
Hazardous Area: An area that poses an immediate or
impending physical hazard.
Hazard Point: The closest reachable point of the hazardous
area.
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.
Key Reset (Manual Reset): A key-operated switch used to
reset a safety light screen system to RUN mode following a
Lockout condition, or to enable machine operation following a
Latch condition. Also refers to the act of using the switch.
Latch Condition: The response of the safety light screen Safety
Outputs (e.g., 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.)
Glossary
Overview
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 (are brought to rest).
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.
Muting: The automatic suspension of the safeguarding function
of a safety device during a non-hazardous portion of the
machine cycle.
OFF State: The state in which the output circuit is interrupted
and does not permit the flow of current.
ON State: The state in which the output circuit is complete and
permits 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.
OSSD: Output Signal Switching Device. The safety outputs that
are used to initiate a stop signal.
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 situation that may exist when
personnel pass through a safeguard (at which point the hazard
stops or is removed), and then continue into the guarded area.
At this point the safeguard may not be able to prevent an
unexpected start or restart of the machine with personnel within
the guarded area.
Point of Operation: The location of a machine where material
or a workpiece is positioned and a machine function is
performed upon it.
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.
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.

Glossary
Overview
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 presencesensing 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 presencesensing 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 screens may not be used as PSDI devices
on mechanical power presses, per OSHA regulation 29 CFR
1910.217.
Qualified Person: An individual who, by possession of a
recognized degree or certificate of professional training, or by
extensive knowledge, training, and experience, has successfully
demonstrated the ability to solve problems relating to the subject
matter and work. (See Designated Person.)
Receiver: The light-receiving component of a safety light
screen, consisting of a row of synchronized phototransistors.
The receiver, together with the emitter (placed opposite), creates
a “screen of light” called the defined area.
Reduced Resolution: A feature that allows a safety light
screen to be configured to produce one or more intentionally
disabled light beam(s) within the light screen, which increases
the minimum object sensitivity. The disabled beam(s) appears
to move up and down (“float”) in order to allow the feeding of
an object through the defined area at any point without tripping
the safety outputs (e.g., OSSDs) and causing a Trip or Latch
condition. Sometimes called “Floating Blanking.”
Reset: The use of a manually operated switch to restore
the safety outputs to the ON state from a lockout or a Latch
condition.
Resolution: See Minimum Object Sensitivity.
Safety Distance: 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 safety distance include
the machine stop time, the light screen system response time,
and the light screen minimum object detection size. Also known
as “Minimum Distance” (EN and ISO) and “Separation Distance”.
EZ-SCREEN LP
Instruction Manual
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 screens 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.
Start/restart (interlock): When applied to the function of a safety
or safeguarding device, this term refers to the ability of the device
to prevent or allow the machine operating cycle to begin or
resume by normal actuating means after the cause of a stop has
been removed. This function is also called “reset”.
NOTE:The reset (clearing of the Start/Restart interlock) of
the device must not cause hazardous motion or a hazardous
situation, but only enable the normal start command.
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.
Test Piece: An opaque object of sufficient size used to block a
light beam to test the operation of a safety light screen.
Trip Condition: The response of the safety outputs (e.g.,
OSSDs) of a safety light screen 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.)
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.
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.
