The EZ-SCREEN SLS 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 EN ISO 13849-1 Categories 3 and 4 without a third box, a controller or a "smart"...
Page 11: Appropriate Applications And Limitations
Qualified Person. The ability of the EZ-SCREEN SLS 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 SLS cannot provide the protection for which it was designed.
Page 12: Examples: Appropriate Applications
Control Reliability: Redundancy and Self-Checking Redundancy requires that EZ-SCREEN SLS circuit components be backed up to the extent that, if the failure of a single com- ponent will prevent effective machine stopping action when needed, that component must have a redundant counterpart which will perform the same function.

Page 21: Chapter 5 Installation Instructions
Mechanical Installation Considerations The two primary factors that influence the layout of the EZ-SCREEN SLS system mechanical installation are: • Safety Distance (Minimum Distance) (see "Calculating the Safety Distance (Minimum Distance)"...
Page 22: Calculating The Safety Distance (Minimum Distance)
The distance is calculated so that when an object or a person is detected (by blocking a sensing beam), the EZ-SCREEN SLS sends a stop signal to the machine, causing it to stop by the time the object or person can reach any machine hazard point.

Example Calculation for European Applications...
Page 25: Reducing Or Eliminating Pass-Through Hazards
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. The EZ-SCREEN SLS Safety Light Cur- tain provides a configurable Manual Start/Restart (Latch Output) function for these applications.
Page 26: Supplemental Safeguarding
EZ-SCREEN SLS Safety Light Curtain Instruction Manual WARNING: • Install reset switches properly • Failure to properly install reset switches could result in serious injury or death. • Install reset switches so that they are accessible only from outside, and in full view of, the safe- guarded space.
Page 27: Emitter And Receiver Orientation
The EZ-SCREEN SLS, in conjunction with the hard (fixed) guarding, is the primary safeguard. Supplemental safe- guarding (such as a horizontal-mounted safety light screen as an area guard) is required in areas that cannot be viewed from the reset switch (for example, behind the robot and the conveyor).
Page 28: Adjacent Reflective Surfaces
EZ-SCREEN SLS Safety Light Curtain Instruction Manual WARNING: • Properly install system components • Incorrectly orienting the system components impairs the performance of the system and results in incomplete guarding, which can result in serious injury or death. • Install the system components with their corresponding cable ends pointing in the same direction.
Page 29: Use Of Corner Mirrors

Page 34: Mounting The Reset Switch
Emitter and receiver wiring is low voltage; routing the sensor wires alongside power wires, motor/servo wires, or other high voltage wiring may inject noise into the EZ-SCREEN SLS System. It is good wiring practice, and sometimes may be required by code, to isolate emitter and receiver cables from high-voltage wires, avoid routing cables close to “noisy” wiring, and pro- vide a good connection to earth ground.
Page 35: Initial Electrical Connections
Emitter Wiring Options 5.7.1 An EZ-SCREEN SLS emitter with an 8-pin connector can be connected either to its own power supply or to the receiver ca- ble, color-for-color. The color-for-color connection allows the emitter and receiver positions to be interchanged without rewiring.
Page 36: Configuring The System For Initial Checkout
(Factory defaults are for Trip Output, 2-Channel EDM, Reduced Resolution OFF, and Scan Code 1.) For the initial checkout, the EZ-SCREEN SLS System must be checked without power being available to the guarded ma- chine. Final interface connections to the guarded machine cannot take place until the light screen system has been checked out.

Page 38: Optical Alignment Procedure With Mirrors
5.8.4 EZ-SCREEN SLS sensors may be used with one or more corner mirrors for guarding more than one side of an area. The MSM-... and SSM-... rear-surface glass mirrors are rated at 85% efficiency. Thus, excess gain and sensing range are re- duced when using mirrors;...
Page 39: Reduced Resolution/Floating Blanking
One or multiple areas within an EZ-SCREEN SLS sensor pair may be blanked out. The minimum number of beams between two blanked areas is one. Any beam other than the sync beam may be blanked. All beams of a fixed blanked area must stay blocked at all times (after the fixed blanking configuration mode has been exited), for the OSSDs to stay ON.
Page 40: Perform A Trip Test
5.8.7 After optimizing the optical alignment, perform the trip test to verify the detection capability of the EZ-SCREEN SLS System. This test will also verify correct sensor orientation and identify optical short circuits. Once the installation has passed the trip test, the safety outputs may be connected and the commissioning checkout may be performed (initial installations only).

Make the permanent electrical connections as described in "Output Signal Switching Device (OSSD) Output Connections" on page 42 "Final Switching...
Page 43: Final Switching Devices (Fsd) Interfacing Connections
Depending on the application, the use of FSDs can facilitate controlling voltage and current that differs from the OSSD out- puts of the EZ-SCREEN SLS. FSDs can also be used to control an additional number of hazards by creating multiple safety stop circuits.
Page 44: Machine Primary Control Elements (Mpce) And External Device Monitoring (Edm) Input
To ensure an accumulation of failures does not compromise the redundant control scheme (cause a failure to danger), a method to verify the normal functioning of MPCEs or other control devices is required. EZ-SCREEN SLS provides a conve- nient method for this verification: external device monitoring (EDM).
Page 45 Open For EZ-SCREEN SLS receivers with a date code prior to 0834, the monitoring contacts must open within 200 milliseconds of the OSSD outputs turning ON (a clear condition) and must close within 200 milliseconds of the OSSD outputs turning OFF (a blocked condition) or a lockout will occur.
Page 46: Auxiliary (Aux.) Output
5.11 The 5-pin EZ-SCREEN SLS emitter models (model numbers SLSE..-..Q5) provide a Test function. A pair of wires is connect- ed from the emitter to an external switch, typically a normally open contact, held closed.

Because it has redundant microprocessors, the receiver has two DIP switch banks (bank A and bank B) that must be set identically. Failure to do so will cause a Lockout condition when power is applied. Power to the EZ-SCREEN SLS receiver should be OFF when changing DIP switch settings or a Lockout will occur.

A Lockout condition causes the EZ-SCREEN SLS 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. Internal Lockout conditions require a manual reset routine to return the System to Run mode after the failure has been corrected and the input has been correctly cycled.

Page 63: Normal Operation
6.5.1 The EZ-SCREEN SLS powers up in one of two ways, depending on the trip/latch output configuration. If it is set for trip out- put, it powers up and resets automatically; if it is set for latch output, it requires a manual reset procedure after the power-up and sensor alignment.
Page 64: Run Mode
EZ-SCREEN SLS 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 SLS will wait for a manual reset; when a valid reset signal is received and all beams remain clear, the receiver outputs turn ON.
Page 65: Chapter 7 Checkout Procedures
Results should be recorded and kept in the appropriate place (for example, near the machine, and/or in a technical file). Banner Engineering highly recommends performing the System checkouts as described. However, a Qualified Person (or team) should evaluate these generic recommendations considering their specific application and determine the appropriate frequency of checkouts.
Page 66: Commissioning Checkout
Perform this checkout procedure as part of the System installation after the System has been interfaced to the guarded ma- chine, or whenever changes are made to the System (either a new configuration of the EZ-SCREEN SLS or changes to the machine).
Page 67: Shift/Daily Checkout
A copy of checkout results should be recorded and kept in the appropriate place (for example, near or on the ma- chine, in the machine’s technical file). Refer to the procedure detailed on the Daily Checkout card (Banner p/n 113361 for SLS.. models, P/N 118173 for SLSC.. models), which can be downloaded from www.bannerengineering.com.

Page 69: Chapter 8 Cascade
Overview of Cascading EZ-SCREEN SLS emitters and receivers are also available in cascadable models. These models can be used as stand-alone light screens, or can be cascaded up to four systems. The cascaded sensor pairs can be any length, any number of beams, or have different resolutions (14 mm and 30 mm), as long as each emitter matches its own receiver.
Page 70: System Components And Specifications
In a cascaded system, all receivers are connected together, and all emitters are connected together. System Components and Specifications A stand-alone cascadeable EZ-SCREEN SLS system includes a compatible emitter and receiver (equal length and resolu- tion; available separately or in pairs), a terminator plug for the receiver and two single-ended (machine interface) cables.

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.
Page 79: Emergency Stop Buttons And Rope/Cable Pulls
Emergency Stop Buttons and Rope/Cable Pulls Cascadeable EZ-SCREEN SLS receivers may be connected to one or more emergency stop buttons. Connect the button(s) to the end of the last receiver in the cascade, in place of the terminator plug. The connected e-stop button(s) will activate/de- activate the OSSD outputs in all receivers in the cascade.
Page 80: E-Stop Switch Requirements (Positive-Opening)
Also, when two or more e-stop switches are used, each switch must be individually actuated (en- gaged), then re-armed and the EZ-SCREEN SLS light curtain reset (if using latch mode). This al- lows 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.

• Incorrect system installation could result in serious injury or death. • The installation of the EZ-SCREEN SLS must prevent any individual from reaching around, under, over or through the defined area and into the hazard without being detected. •...
Page 82: Monitoring Series-Connected Positive-Opening Safety Switches
SLS de-energizes its OSSD output and disables its reset function until the input requirements are met (i.e., the faulty switch is replaced). However, when a series of interlocking safety switches is monitored by the EZ-SCREEN SLS, the failure of one switch in the system may be masked or not detected at all .
Page 83 EZ-SCREEN SLS considers the failure to be corrected. With the input requirements apparently sat- isfied, the EZ-SCREEN SLS allows a reset. This system is no longer redundant and, if the second switch fails, may result in an unsafe condition (i.e., the accumulation of faults results in the loss of the safety function).
Page 84 Open and close each guard separately while verifying that the EZ-SCREEN SLS outputs operate correctly throughout the check procedure. Follow each gate closure with a manual reset, if needed. If a contact set fails, the EZ-SCREEN SLS will not enable its reset function. If the EZ-SCREEN SLS does not reset, a switch may have failed; that switch must be immediately replaced.
Page 85: Chapter 9 Troubleshooting
