PROTECTOR SERIES LIGHT CURTAIN OVERVIEW
Rockford Systems Protector Series Light Curtain is a two-piece (emitter and receiver), redundant, microprocessor-controlled, opposed-mode
optoelectronic "light curtain" or "safety light screen". Models are available in 14 mm, 23 mm, or 40 mm resolution. Up to four pairs of SLLC.. model
emitters and receivers can be cascaded together.
Emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a robust, compact metal housing. Receivers have
a corresponding row of synchronized photodetectors. The sensing field created by the emitter and receiver is called the "defined area"; its width
and height are determined by the length of the sensor pair and the distance between them. The sensing range spans:
• 280 mm to 1820 mm length models: 0.1 m to 12 m (4 in to 39 ft)
• 1890 mm to 2380 mm length models: 0.1 m to 10 m (4 in to 32.8 ft)
The range decreases with the use of corner mirrors and/or lens shields:
• Lens shields — approx 10% less range per shield
• Glass-surface mirrors — approx 8% less range per mirror
The length of the sensor pair (housing) is dependent on the model, with lengths available from 280 mm to 2380 mm (11 in to 93.7 in). The end to
end sensing design of the Protector Series Light Curtain, also known as "no blind zone" and "no dead zone," allows mounting with minimal or no
gaps in detection when using EZLSA-MBK-12 center-mount or EZLSA-MBK-16 side-mount brackets.
The Protector Series Light Curtain models have trip output (auto power-up and automatic reset). In typical operation, if any part of an operator's
body (or any opaque object) of more than a pre-determined cross section is detected, the solid-state output signal switching device (OSSD) safety
outputs turn Off. These safety outputs are connected to the guarded machine's final switching devices (FSDs) that control the machine primary
control elements (MPCEs), which immediately stop the motion of the guarded machine. When the defined area becomes clear, the OSSD outputs
are allowed to turn ON.
Protector Series Light Curtain sensors are extensively FMEA (Failure Mode and Effects Analysis) tested to establish an extremely high degree of
confidence that when properly installed, no system component (even if it should ever fail) can cause a failure to danger. Because of the dual scan
technology, Protector Series Light Curtain sensors are also highly immune to EMI, RFI, ambient light, weld flash, and strobe light.
Eight-conductor Protector Series Light Curtain systems (receivers with 8-pin pigtail QD or flying leads) do not require an external controller when
using the external device monitoring (EDM) function. This function ensures the fault detection capability required by U.S. Control Reliability and ISO
13849-1 Categories 3 or 4 and PL d or e for controlling final switching devices (FSDs) or Machine Primary Control Elements (MPCEs).

PROTECTOR SERIES LIGHT CURTAIN OVERVIEW
When configured with a five-conductor hookup, the Protector Series Light Curtain requires a self-checking safety module, safety controller, or safety
PLC/PES that conforms to the level of performance required by the risk assessment. Examples include the UM-FA-9A/-11A safety module, SC10-
2roe or XS/SC26-2 safety controller for applications requiring Control Reliability and/or ISO 13849-1 Categories 3 or 4 and PL d or e.
Electrical connections (power, ground, inputs and outputs) are made via M12 quick-disconnect cordsets or unique RD (removable disconnect)
cordsets, depending on model. A "System" as referred to in this manual, is defined as an emitter and its receiver, plus their cabling, or to a cascade
of emitters and their receivers and their cabling.
Available features include selectable scan code via hookup, an auxiliary fault output, a recessed exit window, and robust metal housing and end-
caps for industry leading durability.
Additional features on cascade models include automatic configuration of up to four sensor pairs (any length or resolution), optional Protector Series
Light Curtain indication (integral or remotely located) the ability to interface an E-Stop button or Interlocking switches (hard contacts), and remote
fixed blanking. All models require a supply voltage of +24 V dc ±15%.
Both emitter and receiver feature 7-segment Diagnostic Displays and individual LEDs to provide continuous indication of operating status,
configuration and error conditions. An adhesive Diagnostics label is provided that includes a summary of the operational and error codes. Active
Alignment (Segment) Indicators provide beam block information and easier installation. See Status Indicators on page 55 for more information.
APPROPRIATE APPLICATIONS AND LIMITATIONS
APPROPRIATE APPLICATIONS
The Protector Series Light Curtainability 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 Protector Series Light Curtain cannot provide the protection for which it was designed.
Protector Series Light Curtain is typically used for, but is not limited to, the following applications:
• Automated production equipment
• Robotic work cells
• Molding and power presses
• Assembly and packaging machines
• Lean manufacturing systems
WARNING:
• Read this Section Carefully Before Installing the System
• Failure to follow these instructions could result in serious injury or death.
• If all mounting, installation, interfacing, and checkout procedures are not followed properly, this Banner Engineering device cannot provide
the protection for which it was designed.
• The user is responsible for ensuring that all local, state, and national laws, rules, codes, or regulations relating to the installation and use
of this control system in any particular application are satisfied. Ensure that all legal requirements have been met and that all technical
installation and maintenance instructions contained in this manual are followed.
• The user has the sole responsibility to ensure that this Banner Engineering device is installed and interfaced to the guarded machine by
Qualified Persons, in accordance with this manual and applicable safety regulations. A Qualified person is a person who, by possession
of a recognized degree or certificate of professional training, or who, by extensive knowledge, training and experience, has successfully
demonstrated the ability to solve problems relating to the subject matter and work.
WARNING:
• Install System Only on Appropriate Applications
• Failure to follow these instructions could result in serious injury or death.
• Use Rockford System Protector Series Light Curtain only on machinery that can be stopped immediately after a stop signal is issued at any
point in the machine's stroke or cycle, such as part-revolution clutched machines. Under no circumstances may the Protector Series Light
Curtain be used on full-revolution clutched machinery or in unsuitable applications.
• If there is any doubt about whether or not your machinery is compatible with the Protector Series Light Curtain, contact Banner Engineering.

EXAMPLES: INAPPROPRIATE APPLICATIONS
CONTROL RELIABILITY: REDUNDANCY AND SELF-CHECKING
COMPONENTS
MODELS
A Protector Series Light Curtain “System” refers to a compatible emitter and receiver of equal length and resolution (available in pairs or separately),
including cascaded sensors, and their cordsets. Mounting hardware may be included with each emitter and receiver, depending on model. Special-
purpose mounting brackets both for standalone pairs and for cascades are also available. Depending on the connection option, interfacing solutions
include IM-T-.. modules, redundant positively guided contactors, safety modules/controllers, and muting modules.
The 13 mm (0.5 in) minimum bend radius for all cordset models accommodates low-clearance installations; cords can exit to the left, right, or back
of the sensor, when mounting. The pigtail QD option is useful for connection to splitter cables or other QD cordsets.
If a Protector Series Light Curtain is installed for use as a perimeter guard (where a pass-through hazard may exist, see Reducing or Eliminating
Pass-Through Hazards on page 26), the dangerous machine motion can be initiated by normal means only after the safeguarded area is clear of
individuals and the Protector Series Light Curtain has been manually reset.
Do not use Protector Series Light Curtain in the following applications:
• With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or full-revolution) clutched machinery
• With any machine with inadequate or inconsistent machine response time and stopping performance
• With any machine that ejects materials or component parts through the defined area
• In any environment that is likely to adversely affect photoelectric sensing efficiency. For example, corrosive chemicals or fluids or unusually severe levels of
smoke or dust, if not controlled, may degrade sensing efficiency
• As a tripping device to initiate or reinitiate machine motion (PSDI applications), unless the machine and its control system fully comply with the relevant
standard or regulation (see OSHA 29CFR1910.217, NFPA 79, ANSI B11.19, ISO 12100, IEC 60204-1, IEC 61496-1, or other appropriate standard)
Redundancy requires that Protector Series Light Curtain 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 Protector Series Light Curtain is designed with redundant microprocessors.
Redundancy must be maintained whenever the Protector Series Light Curtain is in operation. Because a redundant system is no longer redundant
after a component has failed, Protector Series Light Curtain 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 Protector Series Light Curtain into a Lockout condition.
A recovery from this type of Lockout condition requires:
• Replacement of the failed component (to restore redundancy)
• The appropriate reset procedure
The Diagnostic Display is used to diagnose causes of a Lockout condition. See Troubleshooting on page 60.

OPERATING FEATURES
TRIP OUTPUT
The Rockford Systems Protector Series Light Curtain models described in this manual feature several functions (depending on model).
The System is configured for Trip Output which allows the System to enter Run mode automatically. Other measures must be taken to prevent a
pass-through hazard; see Reducing or Eliminating Pass-Through Hazards on page 26 and the warning below for more information.
The OSSD outputs turn ON after power is applied, and the receiver passes its internal self-test/synchronization and recognizes that all beams are
clear. The Trip Output also automatically resets after all beams are cleared.
WARNING:
• Use of automatic (trip) or manual (latch) start/restart
• Failure to follow these instructions could result in a serious injury or death.
• Applying power to the Banner Engineering device, clearing the defined area, or resetting a latch condition must not initiate dangerous
machine motion. Design the machine control circuitry so that one or more initiation devices must be engaged to start the machine (a
conscious act), in addition to the Banner Engineering device going into Run mode.
EXTERNAL DEVICE MONITORING (EDM)
The External Device Monitoring (EDM) feature allows the Protector Series Light Curtain to monitor the status of external devices, such as MPCEs. The
choices are 1-channel monitoring or no monitoring. EDM is used when the Protector Series Light Curtain OSSD outputs directly control the MPCEs
or other external devices.
This feature is only available when an 8-conductor interface is used.

FAULT OUTPUT
The current sourcing (PNP) solid-state output (70 mA maximum) is used for control functions that are not safety related; a typical use is to signal a
lockout (fault) to a programmable logic controller (PLC). Available on both the receiver and emitter, the output provides a fault signal (lockout = On).
Interrupting (blocking) the sensing field is not considered a lockout, so the Fault Output does not change state.
This feature is available only when an 8-conductor interface is used.
SCAN CODE CONFIGURATION
WIRING OPTIONS
Use the scan code to allow operation of multiple pairs of emitters and receivers in close proximity without the effects of cross-talk. The emitter and
receiver may be configured to use one of two scan codes (1 or 2); a receiver recognizes light only from an emitter with the same scan code. Set the
scan code using the wiring on each sensor (see Scan Code Select on page 49). The scan code is configured at power-up and remains set until the
input is changed and power is cycled. Both the emitter and its corresponding receiver must have the same setting. Cascaded emitters and receivers
automatically alternate scan codes based on the scan code of the first (master) pair.
This feature is only available when an 8-conductor interface is used.
The Machine Interface connection has several options, including:
• A 300 mm (1 ft) pigtail cable with an 8-pin M12/Euro-style male quick disconnect (QD)
• A 300 mm (1 ft) pigtail cable with a 5-pin M12/Euro-style male quick disconnect (QD)
• The Removable Disconnect (RD) that can mate with either a double-ended RD cordset as an interconnect between cascaded sensors or an 8-wire flying
lead RD cordset
Each connection option is intended for maximum flexibility to solve unique application requirements such as directly connecting the Protector Series
Light Curtain to remotely located safety I/O blocks. For interfacing modules or remotely located safety I/O blocks where pin 5 of a 5-pin M12 QD
is not earth ground, a 4-pin cordset where pin 5 is not physically present or is not electrically connected can be used (such as MQDEC-406SS
double-ended cordset). In such situations, earth ground must be provided via the mounting brackets.
Additionally, a Protector Series Light Curtain emitter can be connected either to its own power supply or to the receiver cable, color-for-color. The
color-for-color wiring allows the emitter and receiver positions to be interchanged (swapped) without rewiring.

CASCADING
Up to four sensor pairs (any length or resolution) can be combined into one system. The cascade system automatically configures at power up when
the terminator plug is installed (pre-installed from factory) or when a standard sensor pair or an interfacing cordset is used at the end of the series.
Double-ended DELS-11xE cordsets are required for connecting sensors in a cascade.

PROTECTOR SERIES LIGHT CURTAIN INDICATION
Protector Series Light Curtain cascading models have the ability to connect and remotely locate an EZ-LIGHT or other indicator using a DELSEF-4xD
cordset. Solid-state current sourcing (PNP) outputs (24 V DC at 100 mA) allow for the connection of remote indicators or other devices for non-safety
status information that includes OSSDs ON or OSSDs OFF/Lockout (flashing).
Additionally, EZ-LIGHT model EZLSA-K30LGR (patent pending) is designed to mount directly to the end of a cascade receiver via the cascade RD
connector. The EZLSA-K30LGR provides a replaceable integral solution with a bright 360° red/green indication.
For the Protector Series Light Curtain standard (non-cascade) 8-pin pigtail QD models, a CSB-M128..M1281 splitter cable and optional DEE2R-8..D
double-ended cables can be used with specific models of EZ-LIGHTs at the machine interface connection. The EZ-LIGHT can be remotely mounted
on the machine frame or another convenient mounting surface and provides clear, 360°indication of the Protector Series Light Curtain receiver’s
OSSD output status.
For both standard and cascade solutions, refer to the EZ-LIGHTS listed in the Accessories on page 74.
INTERFACING AN E-STOP BUTTON OR INTERLOCKING SWITCH
REMOTE FIXED BLANKING
Protector Series Light Curtain cascading models can connect electrical (hard) contacts from external devices, such as emergency stop buttons and
interlocking switches, by using an RDLS-8..D cordset. The cascade input may be used to monitor emergency stop buttons, interlocked gates, or
guards and meets or exceeds the requirements for OSHA/ANSI control reliability and up to Category 4 PLe, per ISO 13849-1.
On cascade models, fixed blanking is available to, in effect, "disable" beams that would otherwise be continually blocked by a stationary object. One
or multiple areas within a Protector Series Light Curtain sensor pair may be "blanked out," with a minimum of one beam between two blanked areas.
The first sensing beam (CH1 synchronization beam) at the display end of sensor must remain clear (cannot be blanked); any other beam may be
blanked. All beams of a fixed blanked area must remain blocked during operation in order for the OSSDs to remain ON.
The Remote Fixed Blanking feature can be used on a Protector Series Light Curtain cascade receiver as a stand-alone system or in a cascaded
system. A DELSEF-81D cordset used with a EZA-RBK-1 Remote Blanking Key Switch and indicator provides a convenient means to program the
blanked area. (See Remote TEACH Fixed Blanking (Wiring) on page 73.)
The remote programming is effective on all receivers in the cascaded systems (for example, multiple areas can be blanked on different sensor pairs).
After programing, the EZA-RBK-1 Remote Blanking Key Switch can be removed (with power OFF) and replaced by the terminator plug, an EZ-LIGHT
(integral or remotely mounted), or an Emergency Stop/Interlocking switch via a RDLS-8..D cordset.
