Page 7: Introduction
Banner S4B emitters and receivers provide a redundant, microprocessor-controlled, opposed-mode optoelectronic safety light screen. S4B typically is used for point-of-operation safeguarding, and is suited to safeguard a variety of machinery. The S4B emitters have a row of synchronized modulated infrared (invisible) light-emitting diodes (LEDs) in a compact housing. -
Page 8: Components
S4B Safety Light Curtain 3.2.1 Components An S4B “System” refers to a compatible emitter and receiver (equal length and resolution), and cordset(s) for each. RD to M12 cordsets, side mounting brackets, and specified test pieces are sold separately. Figure 1. Main Components 1. -
Page 9: Appropriate Applications And Limitations
Qualified Person. The ability of the S4B 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 S4B cannot provide the protection for which it was designed. -
Page 10: Examples: Inappropriate Applications
3.4 Control Reliability: Redundancy and Self-Checking Redundancy requires that S4B 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. -
Page 11: Trip Output
Failure to follow these instructions could result in a serious injury or death. • Applying power to the Banner 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 device going into Run mode. -
Page 12: Weak Beam Strength Indication
S4B Safety Light Curtain 3.5.3 Weak Beam Strength Indication Weak beam strength is indicated when one or more channels are made, but the beam strength is marginal. This indication can be used to aid alignment of the sensor and also to indicate when window cleaning might be needed. -

2 The maximum voltage allowed on the OSSDs in the OFF-state without a lockout occurring. This voltage may occur, for example, from the input structure of a safety relay module connected to the S4B OSSDs. 3 Maximum current occurs at a supply voltage of 20 V DC. -
Page 15: Mechanical Installation
The distance is calculated so that when an object or a person is detected (by blocking a sensing beam), the S4B sends a stop signal to the machine, causing it to stop by the time the object or person can reach any machine hazard point. -
Page 16: Formula And Examples
(or the hazard removed). This can be broken down into two parts: Ts and T r where T = T s + T r the maximum response time, in seconds, of the S4B emitter/ receiver pair (depending on model) -
Page 17: Examples
S = (1600 × 0.32) + 128 = 640 mm Mount the S4B emitter and receiver so that no part of the defined area will be closer than 640 mm to the closest reachable hazard point on the guarded machine. -
Page 18: Reducing Or Eliminating Pass-Through Hazards
Safety Light Curtain/Screen Reset Switch This is an example of supplemental safeguarding inside a robotic work cell. The S4B, in conjunction with the hard (fixed) guarding, is the primary safeguard. Supplemental safeguarding (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 19: Reset Switch Location
5.5 Reset Switch Location The S4B has a trip output (auto power-up and automatic reset) that turns the OSSD outputs ON when the defined area is unobstructed (clear). Per application requirements, a latch response requiring a manual reset to a power-up condition or after an interruption has cleared the defined area might be required. -
Page 20: Other Considerations
S4B Safety Light Curtain 5.6 Other Considerations 5.6.1 Adjacent Reflective Surfaces A reflective surface located 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. -
Page 21: Use Of Corner Mirrors
850 mm (33.5 in) 5.6.2 Use of Corner Mirrors S4B may be used with one or more corner mirrors. Mirrors are not allowed for applications that would allow undetected personnel access into the safeguarded area.

Page 28: Electrical Installation And Testing
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 S4B System. It is good wiring practice, and sometimes may be required by code, to isolate emitter and receiver cables from high-voltage wires and to avoid routing cables close to sources of noise. - Page 29 S4B Safety Light Curtain The default scan code setting is scan code 1. To change the scan code setting, use the following instructions. 1. Remove the DES4E-51D cordset from the sensor by loosening the two screws (#1 Phillips drive). Note: The screws are captive screws and should not be removed from the cordset assembly.
-
Page 30: Initial Electrical Connections
All connections are made through the DES4E-51D connection. Emitter Cordset S4B emitters require a mating 5-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, providing sensor interchangeability (or “swapability”); either sensor may be installed at either cordset connection. -

Page 34: Electrical Connections To The Guarded Machine
Output Signal Switching Devices (OSSDs) and External Device Monitoring (EDM) The S4B is able to detect faults on OSSD1 and OSSD2. These faults include short circuits to +24 V DC and 0 V, and between OSSD1 and OSSD2. Both 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. -
Page 35: Preparing For System Operation
(FSDs and/or MPCEs). The S4B System does not include the EDM function. As a result, the S4B System should be used with an external safety monitoring device that monitors the status of the two S4B OSSDs and is capable of providing the EDM function. -
Page 36: Sensor Interchangeability
Perform this checkout procedure as part of the System installation after the System has been interfaced to the guarded machine, or whenever changes are made to the System (either a new configuration of the S4B or changes to the machine). - Page 37 15. 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. 16. Remove electrical power to the S4B. Both OSSD outputs should immediately turn Off, and the machine must not be capable of starting until power is re-applied to the S4B.

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. 7.2.2 Run Mode If any beams become blocked while the S4B is running, the receiver outputs turn Off within the stated S4B response time (see Specifications on page 13). -

All S4B wiring is low voltage; running these wires alongside power wires, motor/servo wires, or other high-voltage wiring can inject noise into the S4B System. It is good wiring practice (and may be required by code) to isolate S4B wires from high- voltage wires. -
Page 43: Check For Sources Of Optical Noise
S4B Safety Light Curtain 3. Press the RCV button on the BT-1 and position the Beam Tracker on the wires going to the S4B or any other nearby wires. 4. If the BT-1's indicator lights, check for sources of electrical noise and separate the S4B cordset from any high-voltage wiring, if applicable. -
Page 44: 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. -
