System Introduction
EZ-SCREEN Grid
Instruction Manual
1. Introduction — Overview
1.1 System Description
The Banner EZ-SCREEN™ Grid System is an optically synchronized,
microprocessor-controlled, opposed-mode optoelectronic “light grid.” This
economical two-part system consists of an emitter and receiver. The system
requires no external controller or sync wire between the emitter and receiver; the
microprocessors are located within the receiver. The receiver has two solid-state
safety outputs to control 24V dc loads. If an ac-powered MPCE or other load is
required, an accessory interface module may be used to convert the EZ-SCREEN
dc outputs to isolated, forced-guided relay contacts. (See Section 2.2 and Figures
3-17 and 3-18 for more information.)

System Introduction
EZ-SCREEN Grid
Instruction Manual
Five sensor configurations are available, with two, three or four beams; emitters
have short-range and long-range versions. (Receivers are the same for both
long-range and short-range operation.) Beam spacing ranges from 300 mm to
584 mm (12" to 23"), depending on the model. The configuration (the overall
length and beam spacing) required for an application is determined by the
application and the safety standards being followed. Models SG..E/R2-584 and
SG..E/R3-533 are based on recommendations in ANSI/RIA R15.06 and ANSI B11
standards. Models SG..E/R4-300, SG..E/R3-400, and SG..E/R2-500 are based on
recommendations in EN 999. See pages 60 and 61 for a list of applicable safety
standards. Emitters and receivers do not need matching serial numbers to work
together; any emitter may be used with any receiver of the same length and beam
configuration. Figure 1-1 shows the sizes and beam configurations of the models
available.
The emitter/receiver beams feature a narrow effective aperture angle (EAA) for
effective long-range sensing — up to 70 meters, depending on model. The EAA
satisfies IEC 61496-2 (type 4), including requirements for extraneous reflections
and misalignment.
Cabling is accomplished in one of two ways. User-supplied cable may be hard-
wired into the emitter and receiver housings, using the removable terminals in
the end cap of each sensor, or Mini-style quick-disconnect models are available
for easier installation; see pages 57-58. See Section 2.5 for cable specifications
and Section 3.7 for wiring instructions.
Banner EZ-SCREEN Grid components may be purchased individually or in kits.
Kits include one emitter, one receiver, a keyed reset switch, and standard
mounting hardware for both sensors. When purchased separately, the emitter
and receiver each include one cable gland, mounting hardware for one sensor,
plus the accessory spanner wrench. The Key Reset switch also is available
separately, or the user may provide other means to reset the system (see
specifications in Section 2.5 for switch requirements).
The OSSD (solid-state safety outputs) are capable of performing a “handshake”
communication with the Muteable Safety Stop Interface (MSSI) or Universal
Safety Stop Interface (USSI) that are found on other Banner Engineering safety
products. The handshake protocol is satisfied by any Banner Engineering Safety
Category 4 (per ISO 13849-1/EN954-1) device with OSSD outputs or MSSI/USSI
inputs.
To ensure a Safety Category 4 (per ISO 13849-1/EN954-1) interface between the
two devices, the MSSI/USSI provides a “handshake request” that Banner
Engineering safety devices with OSSD solid-state outputs are capable of
responding to. This handshake verifies that the interface between the two devices
is capable of detecting certain unsafe failures that may occur, such as a short-
circuit to a secondary source of power or to the other channel, high input
resistance or loss of signal ground.

Instruction Manual
1.2 Applications and Limitations
The Banner EZ-SCREEN Grid System is designed for use in access-guarding and
perimeter-guarding applications. It is designed to be mounted vertically, in order
to detect a body or torso (rather than a hand or an arm) as a person enters a
hazardous area. It is not intended nor designed for hand or finger detection in
point-of-operation guarding or for area-guarding applications.
In perimeter-guarding and access-guarding applications, the light grid is vertical
or nearly vertical. In these applications, personnel typically can pass through the
light grid (which removes or stops the hazard), then may continue into the
hazardous area.
A recommended set of beam placement positions has become accepted in the
United States and Europe. The standards (ANSI/RIA R15.06, ANSI B11 and
EN 999) recommend a safe beam placement, in order to hinder personnel from
crawling over, under or through the light grid, and into the hazardous area,
without detection. For more information, refer to Section 3.3.1.
WARNING . . .
Not for Point-of-
Operation or Area
Guarding
Do not use the EZ-SCREEN Grid
System for point-of-operation or
non-vertical area guarding.
!
CAUTION . . .
Proper Model
Selection
Ensure proper
selection of emitter models,
with respect to range (operating
distance) between emitter and
receiver, to minimize the
possibility of optical short circuits
(see Sections 2.1 and 3.3.4).

System Introduction
EZ-SCREEN Grid
Instruction Manual
Pass-through hazards: Perimeter- and access-guarding applications must be
designed to prevent pass-through hazards. A pass-through hazard occurs when
an individual is allowed to cross the safeguard (which issues a stop command to
remove the hazard). Subsequently, the person may cross into the hazardous area
but their presence is no longer detected. A danger arises because the machine’s
dangerous motion may resume while personnel are within the safeguarded area.
Several measures can be taken to prevent a pass-through hazard, which include,
but are not limited to:
•Alatching output on the safety light grid guarding the access or perimeter to
the hazardous area, which requires a manual reset procedure before machine
motion can be re-initiated. The reset switch has several requirements,
including its placement outside of the guarded area, and out of reach of
anyone inside the guarded area. In addition, the reset switch operator must
have full view of the entire guarded area during the reset procedure.
•Supplemental safeguarding, such as described by the ANSI B11 series of
safety requirements or other appropriate standards, to prevent personnel
from standing undetected within the guarded area.
In addition, hard guarding should be installed around the hazardous area to
prevent personnel from entering the guarded area, undetected by the safety light
grid, or other safeguarding means.
Because the EZ-SCREEN Grid has a selectable (latch or trip) output, it must be
installed and configured to prevent hazardous motion from occurring while
personnel are within the guarded area. See Section 4.1 for more information.
EZ-SCREEN Grid may be used to guard many types of machines, including
those for packaging, palletizers, roll formers and many types of work cells,
including robot cells. The guarded machine(s) must be capable of stopping at
any point in their motion; see page 2 for a complete list of requirements for
machines that may be guarded by this system.
WARNING . . .
Use of Trip Output
Application of power
to the EZ-SCREEN
Grid System 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 Grid System going into
RUN mode.
Failure to follow these instructions
could result in serious bodily
injury or death.
!
CAUTION . . .
Other Applications
For applications not
covered in this manual, contact
a factory applications engineer
before installing or using the EZ-
SCREEN System.

System Introduction
EZ-SCREEN Grid
Instruction Manual
1.3 Control Reliability
In addition to physical location requirements, safety standards require a safety
system such as the EZ-SCREEN Grid to fulfill some internal requirements. For
example, for an optical safety system to be used in a Safety Category 4
application (per ISO 13849-1/EN954-1), it must be third-party certified to the
type 4 requirements of IEC 61496-1 and -2.
EZ-SCREEN Grid’s microprocessor-based circuitry features a “diverse-redundant”
design, in which two microprocessors of different design, running from different
instruction sets, constantly check all system components, including each other.
In addition, EZ-SCREEN Grid is extensively FMEA (Failure Mode and Effects
Analysis) tested to establish an extremely high probability that no system
component will ever (even if it does fail) cause a failure to danger.
1.4 EZ-SCREEN Grid Operating Features
The Banner EZ-SCREEN Grid System features several selectable functions: trip or
latch output, external device monitoring (EDM), and scan code setting. These
settings are configured within the sensors, behind the threaded access port on
the front of each sensor and in the sensor wiring configuration; see Section 4.1
for more information.
Selectable Trip/Latch Output
The setting for latch or trip output also determines whether the System will enter
Run mode automatically or require a manual reset (see Section 4.1). If the
system is set for trip output, other measures must be taken to prevent a pass-
through hazard; see Section 3.3.2 for more information.

System Introduction
EZ-SCREEN Grid
Instruction Manual
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. The trip output will also automatically reset after all
interruptions of one or more beams are cleared. If latch output is selected, the
EZ-SCREEN requires a manual reset for the OSSD outputs to turn ON, after
power is applied and all beams are clear (see Section 4.2.1).
External Device Monitoring (EDM)
This feature allows the EZ-SCREEN Grid to monitor the status of external devices,
such as MPCEs. The choices are one- or two-channel monitoring, or OFF. EDM is
used when the EZ-SCREEN Grid OSSD outputs directly control the energizing and
de-energizing of the MPCEs or other external devices; see Sections 3.7.3 and 4.1
for more information.
Remote Test Input
A pair of terminals is provided at the emitter (see Section 3.7.4) for an external
switch, typically a normally open contact held closed. Opening a switch
connected between these two terminals “turns off” the emitter, simulating an
interruption of one or more light beams. This remote test input may be useful for
EZ-SCREEN Grid system setup and to verify machine control circuit operation.
Scan Code Configuration
The emitter and receiver may be configured to one of two scan code positions (1
or 2). Scan codes enable a receiver to recognize beams only from an emitter with
the same scan code 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 Section 3.3 for proper mounting
configurations. The scan code is set using the selection switch in each sensor’s
configuration port; see Section 4.1 for more information. Both the emitter and its
corresponding receiver must be set to the identical setting.
Status Indicators
A variety of status indicators on both the system emitter and receiver are clearly
visible on each sensor’s front panel.
• Emitter: A single bi-color red/green Status indicator shows whether power
is applied, and whether the emitter is in Run mode, Test mode, or
Lockout mode. A 7-segment diagnostic display indicates specific
error or configuration conditions.
• Receiver: A bi-color red/green Beam Status indicator for each beam shows
whether that beam is aligned and clear with a strong signal, clear
but with a weak signal, or is blocked and/or misaligned. A yellow
Reset indicator shows when the system is in Run mode or is
waiting for a reset. A bi-color red/green Status indicator shows
when outputs are ON or OFF, or the system is in Lockout mode. A
7-segment diagnostic display indicates specific error or

Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
3. Installation and Alignment
Read Section 3 in its entirety before installing the Banner EZ-SCREEN Grid
System. The Banner EZ-SCREEN Grid 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 EZ-SCREEN Grid System cannot provide the protection
for which it was designed. Installation must be performed by a Qualified Person,
as defined in the Safety Glossary in this manual. See Warning at right.
3.1 Appropriate Applications
The Banner EZ-SCREEN Grid System may be used to guard only machinery that
can be stopped immediately after a stop signal is issued. It may be used with
part-revolution clutched machines that have the ability to stop at any point in
their stroke. Under no circumstances may the EZ-SCREEN Grid System be used
to guard full-revolution clutched machinery. Banner EZ-SCREEN Grid Systems
may not be used as tripping devices to initiate machine motion (PSDI
applications) on mechanical power presses, per OSHA regulation 29 CFR
1910.217.
The Banner EZ-SCREEN Grid System is typically used in access-guarding or
perimeter-guarding applications for the following types of machines:
•Assembly stations
•Manufacturing cells
•Automated production equipment
•Robotic work cells
The Banner EZ-SCREEN Grid System may not be used in the following types of
applications:
•For finger or hand detection in point-of-operation guarding; its beam spacing is
larger than that allowed for finger or hand detection in these applications,
•For non-vertical area-guarding applications,
•To guard any machine that cannot be stopped immediately after a stop signal
is issued, such as single-stroke (or “full-revolution”) clutched machinery,
•To guard any machine with inadequate or inconsistent machine response
time and stopping performance,
•To guard any machine that ejects materials or component parts through the
area protected by the EZ-SCREEN Grid, or
•In any environment that is likely to adversely affect photoelectric sensing
system efficiency. For example, corrosive chemicals or fluids or unusually
severe levels of smoke or dust, if not controlled, may degrade the efficiency of
the safety light grid.
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. Extreme care should
be taken 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
Banner EZ-SCREEN Grid System is
installed and interfaced to the
guarded machine by Qualified
Persons in accordance with this
manual and applicable safety
regulations.
Read 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.
!
CAUTION . . .
Install System Only
on Appropriate
Applications
In order for the machinery guarded
by the EZ-SCREEN Grid system to
be stopped as described, that
machinery must be capable of
stopping at any point in its
machine cycle. This means that the
EZ-SCREEN Grid system cannot be
used with certain types of
machinery (see listing at left).
If there is any doubt about whether
or not your machinery is
compatible with the EZ-SCREEN
Grid system, contact a Banner
factory application engineer.

Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
3.2 Security Protocol
Certain procedures for installing, maintaining and operating the EZ-SCREEN Grid
system must be performed by either Designated Persons or Qualified Persons.
A Designated Person is identified and designated in writing, by the employer, as
being appropriately trained and qualified to perform the specified checkout
procedures on the EZ-SCREEN Grid system. A machine operator so designated
may be a Designated Person. The Designated Person is empowered to:
•Perform manual resets and hold possession of the reset key, and
•Perform the Daily Checkout Procedure (see Section 6).
A Qualified Person, 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 installation
of the EZ-SCREEN Grid System and its integration with the guarded machine. In
addition to everything for which the Designated Person is empowered, the
Qualified Person is empowered to:
•Install the safety light grid system,
•Perform all safety light grid checkout procedures (see Section 6),
•Have access and make changes to the internal light grid configuration settings
and hold possession of the Banner spanner wrench that opens the
configuration access port plug, and
•Reset the system following a lockout condition.
Resetting the System
System resets are performed using an external Reset switch. This switch must be
located outside the guarded area, and not within reach of anyone inside the
guarded area (see Section 3.4). Its location should provide a clear view of the
entire safeguarded area. If any hazardous areas are not within 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).
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.
Reset Routine
The EZ-SCREEN requires a manual reset to clear a latch condition and resume
operation following a stop command. To perform a manual reset, close the
normally open Reset switch for a least 1/4 second, but not longer than 2
seconds, and then re-open the switch. Internal lockout conditions also require a
manual reset to return the system to RUN mode after the failure has been
corrected and the input correctly cycled.

Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
3.3 Mechanical Installation Considerations
Two factors have the greatest influence on the mechanical installation of the
EZ-SCREEN System:
•The required separation (safety) distance, and
•The presence of hard guarding.
3.3.1 Minimum Separation Distance (Ds)
Minimum Separation (Safety) Distance (Ds) is the minimum distance required
between the light grid and the closest reachable hazard point. Separation distance
is calculated so that the EZ-SCREEN Grid System will send a stop signal to the
machine when an object or a person is detected (by blocking a sensing beam),
allowing the machine to come to a stop by the time the person can reach any
machine hazard point.
After the Dsis determined, record the calculated distance in Section 6.4 (step
2) of this manual, and/or on the Daily Checkout Card.

Installation and Alignment
EZ-SCREEN Grid
Instruction Manual
Calculation of separation distance takes into account several factors, including a
calculated human speed, the total system stopping time (which itself has several
components), and the depth penetration factor. The formula used to calculate
separation distance is:
Ds= K x (Ts+ Tr) + Dpf
where:
Ds=the separation distance, in inches;
K=63" per second (or 1600 mm per second), the OSHA-recommended (or
EN 999-recommended) hand-speed constant1;
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, and measured at maximum machine
velocity)2. See the Warnings on page 20, and the Notice Regarding
MPCEs (at left).
This measurement must take into account the slower of the two MPCE
channels, and the response time of all devices or controls (such as
interface modules) that react to stop the machine. If all devices are not
included, the calculated separation distance (Ds) will be too short and
serious injury could result.
Tr=0.024 seconds, the maximum response time of the EZ-SCREEN Grid
System; and
Dpf =36" or 48", the added distance due to depth penetration factor (for U.S.
applications, prescribed in ANSI/RIA R15.06 and ANSI B11). Because the
beam spacing of the EZ-SCREEN Grid is larger than 2.5" but less than
24", Dpf is either 36" or 48":

pf is 36" if the top beam is 48" or higher and the bottom beam is
12" or less from the floor (a reach-through hazard).
•D
pf is 48" if the top beam is 36" to 48" above the floor and the
bottom beam is 12" or less from the floor (a reach-over hazard).
In European applications, Dpf is 850 mm, prescribed in EN 999.
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. The user
should consider all factors, including the physical ability of the operator,
when determining the value of K to be used.
2) Tsis usually measured by a stop-time measuring device. If the machine
manufacturer’s specified stop time is used, at least 20% should be added to
allow for possible clutch/brake system deterioration.

Notice Regarding
MPCEs
Each of the two Machine Primary
Control Elements (MPCE 1 and
MPCE2) must be capable of
immediately stopping the dangerous
machine motion, irrespective of the
state of the other. These two channels
of machine control need not be
identical, but the stop time
performance of the machine (Ts, used
to calculate the separation distance)
must take into account the slower of
the two channels.

EZ-SCREEN Grid
Instruction Manual
U.S. Applications:
Using the formula,
Ds= K x (Ts+ Tr) + Dpf
separation distance for a model SG..3-533 EZ-SCREEN Grid System
(42" protected height with 3 beams, 21" apart) is calculated (per ANSI/RIA
R15.06):
K=63"/second
Ts=0.32 (0.250 second is specified by the machine manufacturer; plus
20% safety factor; plus 20 ms for interface module IM-T-9A response)
Tr=0.024, the maximum response time of the EZ-SCREEN Grid System
in seconds; and
Dpf = 36"
Ds= 63 x (0.32 + 0.024) + 36
Ds= 58"
In this example, the EZ-SCREEN Grid emitter and receiver must be mounted
so that no part of the light grid will be closer than 58" from the closest
reachable hazard point of the guarded machine.
European Applications:
Using the same formula, separation distance for a model SG..3-400 EZ-
SCREEN Grid System (800 mm protected height with 3 beams, 400 mm
apart), is calculated (per EN 999):
K=1600 mm/second
Ts=0.32 (0.250 second is specified by the machine manufacturer; plus
20% safety factor; plus 20 ms for interface module IM-T-9A response)
Tr=0.024, the maximum response time of the EZ-SCREEN Grid System
in seconds; and
Dpf =850 mm
Ds= 1600 x (0.32 + 0.024) + 850
Ds= 1400 mm
In this example, the EZ-SCREEN Grid emitter and receiver must be mounted
so that no part of the light grid will be closer than 1400 mm from the closest
reachable hazard point of the guarded machine.

NOTE: Other machine standards may require different
separation factors from those illustrated. Also,
workers’/operators’ abilities, plant procedures and other
factors may affect Ds.
CAUTION . . .
Position Components
Carefully
The emitter and receiver must be
positioned so that the hazard
cannot be accessed by reaching
over, under, around or through the
sensing field. Supplemental
safeguarding may be required; see
Section 3.3.2.
!
CAUTION . . .
Adequate Separation
Distance
The emitter and receiver must be
positioned a safe distance from
hazardous areas, as described by
OSHA standards in Section
1910.217 (c)(3)(iii)(e). Also see
Section 3.3 of this manual.
Failure to do so could result in
serious bodily injury or death.
!
CAUTION . . .
Determining Correct
Stop Time
Be sure to include the stop time of
all relevant devices and controls in
your calculations. Failure to do so
could result in serious bodily
injury or death.
