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.
