· Defined areas of 300 mm (12 in) to 1800 (71 in) mm, in increments of 150 mm (6 in)
· 0.1 m to 12 m range (4 in to 39 ft); the range decreases with the use of corner mirrors and/or lens shields:
Lens Shields–an approximately 10% reduction in range per shield
Glass-surface mirrors–an approximately 8% reduction in range per mirror
· Zone and Status indicators for diagnostics
· FMEA tested to ensure control reliability
· Highly immune to EMI, RFI, ambient light, weld flash, and strobe light
· Safety PLC input compatible (per OSSD specifications)

3.2 System Description
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. Receivers have a corresponding row of synchronized photodetectors. The light screen 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 defined area (sensing area) is equivalent to the height of the sensors. The maximum sensing range is 12 m (39 ft), which decreases if corner mirrors or lens shields are used. The sensing area extends from end to end of the housing; there is no dead zone.
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 typically connected to an external monitoring device such as a Banner XS26-2 Safety Controller.
Electrical connections (power, ground, inputs, and outputs) are made via M12 quick-disconnect connections.
All models require a supply voltage of +24 V DC ±15%.
Both the emitter and the receiver feature LEDs to provide continuous indication of operating status and error conditions.
All models include the ability to select between two scan codes.

S4B Safety Light Curtain
3.3 Appropriate Applications and Limitations
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 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 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.
The Banner S4B is intended for point-of-operation machine guarding and other safeguarding applications. It is the user’s responsibility to verify whether the safeguarding is appropriate for the application and is installed, as instructed by this manual, by a 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.
WARNING: · Install System Only on Appropriate Applications · Failure to follow these instructions could result in serious injury or death. · Use Banner’s S4B 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 S4B 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 S4B, contact Banner Engineering.
3.3.1 Appropriate Applications
S4B is typically used for, but is not limited to, the following applications: · Small assembly equipment · Automated production equipment · Robotic work cells · Molding and power presses · Assembly and packaging machines · Lean manufacturing systems

S4B Safety Light Curtain

Figure 2. Typical Application

3.3.2 Examples: Inappropriate Applications
Do not use the S4B in the following applications:
· With any machine that cannot be stopped immediately after a stop signal is issued, such as single-stroke (or fullrevolution) 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)
If the S4B is installed for use as a perimeter guard (where a pass-through hazard may exist, see Reducing or Eliminating Pass-Through Hazards on page 18), the dangerous machine motion can be initiated by normal means only after the safeguarded area is clear of individuals and the external safety monitoring device has been manually reset.

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. The S4B is designed with redundant microprocessors.
Redundancy must be maintained whenever the S4B is in operation. Because a redundant system is no longer redundant after a component has failed, S4B 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 S4B into a Lockout condition.
A recovery from this type of Lockout condition requires: · Replacing the failed component (to restore redundancy), and · Performing the appropriate reset procedure.

3.5 Operating Features
The sensing resolution is determined by the emitter and receiver model.
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 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.
Emitter Wiring Options–An S4B emitter can be connected either to its own power supply or to the receiver cable, color-forcolor. The color-for-color wiring allows the emitter and receiver positions to be interchanged without rewiring. Status Indicators–Status indicators on both the emitter and receiver are clearly visible on each sensor’s front panel.

Zone 1 Indicator–indicates beam synchronization status

3.5.1 Trip Output
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 18 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 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.

3.5.2 Scan Code Configuration
Use the scan code to allow operation of multiple pairs of emitters and receivers in close proximity without the effects of crosstalk.
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 switches of the removable disconnect of each sensor (see Scan Code Selection on page 28). Both the emitter and its corresponding receiver must have the same setting.
The default setting is Scan Code 1.

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. The Zone indicator representing the area of the channel(s) with the weak beam strength immediately turns yellow when the marginal signal is detected. The Weak Beam Strength Output, receiver pin 5, turns ON any time one or more channels are detected with a marginal signal for longer than 1 minute. After the signal rises above the marginal level, the Weak Beam Strength Output turns OFF.

S4B Safety Light Curtain
5 Mechanical Installation
The S4B system performance as a safety guarding device depends on: · The suitability of the application · The proper mechanical and electrical installation and interfacing to the guarded machine
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 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 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.

5.1 Mechanical Installation Considerations
The two primary factors that influence the layout of the S4B system mechanical installation are: · Safety Distance (Minimum Distance) (see Calculating the Safety Distance (Minimum Distance) on page 15) · Supplemental safeguarding/eliminating pass-through hazards (see Reducing or Eliminating Pass-Through Hazards on page 18)
Other considerations include: · Emitter and Receiver Orientation (see Emitter and Receiver Orientation on page 22) · Adjacent Reflective Surfaces (see Adjacent Reflective Surfaces on page 20) · Use of Corner Mirrors (see Use of Corner Mirrors on page 21) · Installation of Multiple Systems (see Installation of Multiple Systems on page 23)
WARNING: · Position the System Components Carefully · Failure to observe this warning could result in serious injury or death. · Position the system components such that the hazard cannot be accessed by reaching over, under, around, or through the sensing field. Additional and supplemental guarding may be required.

5.2 Calculating the Safety Distance (Minimum Distance)
Safety Distance (Ds), also called Minimum Distance (S), is the minimum distance required between the defined area and the closest reachable hazard point. 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.
The distance is calculated differently for U.S. and European installations. Both methods take into account several factors, including a calculated human speed, the total system stopping time (which itself has several components), and the depth penetration factor. After the distance has been determined, record the calculated distance on the Daily Checkout Card.
WARNING: · Calculate the Safety Distance (Minimum Distance) · Failure to establish and maintain the safety distance (minimum distance) could result in serious injury or death. · Mount the components at a distance from the nearest hazard such that an individual cannot reach the hazard before cessation of the hazardous motion or situation. Calculate this distance using the supplied formulas, as described by ANSI B11.19 and ISO 13855. Mount the components more than 100 mm (4 in) away from the hazard, regardless of the calculated value.

5.2.1 Formula and Examples
U.S. Applications The Safety (Separation) Distance formula for U.S. applications: Ds = K × (Ts + Tr) + Dpf

European Applications The Minimum Distance formula for European applications: S = (K × T) + C

Ds the Safety Distance (in inches)
K
1600 mm per second (or 63 in per second), the OSHA 29CFR1910.217, and ANSI B11.19 recommended hand-speed constant (see Note 1 below)
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 (for example, XS26-2 Safety Controllers) and measured at maximum machine velocity (see Note 3 below)
Tr the maximum response time, in seconds, of the S4B emitter/ receiver pair (depending on model)
Dpf the added distance due to the depth penetration factor as prescribed in OSHA 29CFR1910.217, and ANSI B11.19 for U.S. applications. See Depth Penetration Factor (Dpf) table below or calculate using the formula (in mm): Dpf = 3.4 × (S ­ 7) where S is the resolution of the light curtain (for S 63 mm).

S the Minimum Distance, in mm, from danger zone to light screen center line; minimum allowable distance is 100 mm ( 175 mm for non-industrial applications), regardless of calculated value
K hand-speed constant (see Note 2 below); 2000 mm/s (for Minimum Distances < 500 mm) 1600 mm/s (for Minimum Distances > 500 mm)
T the overall machine stopping response time (in seconds), from the physical initiation of the safety device and the machine coming to a stop (or the hazard removed). This can be broken down into two parts: Ts and Tr where T = Ts + Tr
C the additional distance, in mm, based on intrusion of a hand or object towards the danger zone prior to actuation of a safety device. Calculate using the formula (in mm):
C = 8 × (d – 14)
where d is the resolution of the light curtain (for d 40 mm), or use 850 mm for C.

Notes: 1. The OSHA-recommended hand speed constant K has been determined by various studies and, although these studies indicate speeds of 1600 mm/sec. (63 in/sec.) to more than 2500 mm/sec. (100 in/sec.), they are not conclusive determinations. Consider all factors, including the physical ability of the operator, when determining the value of K to be used. 2. The recommended hand speed constant K, derived from data on approach speeds of the body or parts of the body as stated in ISO 13855. 3. Ts is 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. This measurement must take into account the slower of the two MPCE channels, and the response time of all devices or controls that react to stop the machine.
WARNING: · Stop time (Ts) must include the response time of all devices or controls that react to stop the machine · If all devices are not included, the calculated safety distance (Ds or S) will be too short, which can lead to serious injury or death. · Include the stop time of all relevant devices and controls in your calculations. · If required, each of the two machine primary control elements (MPCE1 and MPCE2) must be capable of immediately stopping the dangerous machine motion, regardless 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 safety distance) must take into account the slower of the two channels.
5.2.2 Examples
U.S. Applications, Model S4BR30-600-S
K = 63 inches per second (the hand speed constant set by OSHA) Ts = 0.31 (0.250 second is specified by the machine manufacturer; plus 20% safety factor; plus 13 ms for XS26-2
Safety Controller response time) Tr = 0.010 seconds (the specified response time of a S4BR30-600-S System) Dpf = 3.1 inches (30 mm resolution) Substitute the numbers into the formula as follows:
Ds = K × ( Ts + Tr ) + Dpf
Ds = 63 × (0.31 + 0.010) + 3.1 = 23.3 in Mount the S4B emitter and receiver so that no part of the defined area will be closer than 23.3 inches to the closest reachable hazard point on the guarded machine.
European Applications, Model S4BR30-600-S
K = 1600 mm per second T = 0.32 (0.250 second specified by machine manufacturer; plus 20% safety factor; plus 13 ms XS26-2 Safety
Controller response time), plus 0.010 seconds (the specified response time of a S4BR30-600-S System) C = 8 × (30 ­ 14) = 128 mm (30 mm resolution) Substitute the numbers into the formula as follows:
S = (K × T ) + C
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.

S4B Safety Light Curtain

5.3 Reducing or Eliminating Pass-Through Hazards
A pass-through hazard is associated with applications where personnel may pass through a safeguard, such as the S4B Safety Light Curtain (which issues a stop command to remove the hazard), and then continues into the guarded area. This is common in access and perimeter guarding applications. Subsequently, their presence is no longer detected, and the related danger becomes the unexpected start or restart of the machine while personnel are within the guarded area.
In the use of light screens, a pass-through hazard typically results from large safety distances calculated from long stopping times, large minimum object sensitivities, reach-over, reach-through, or other installation considerations. A pass-through hazard can be generated with as little as 75 mm (3 in) between the sensing field and the machine frame or hard (fixed) guarding.
Eliminate or reduce pass-through hazards whenever possible. While it is recommended to eliminate the pass-through hazard altogether, this may not be possible due to machine layout, machine capabilities, or other application considerations.
One solution is to ensure that personnel are continually sensed while within the hazardous area. This can be accomplished by using supplemental safeguarding, such as described by the safety requirements in ANSI B11.19 or other appropriate standards.
An alternative method is to ensure that after the safeguarding device is tripped, the corresponding safety monitoring device latches and requires a deliberate manual action to reset. 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 S4B Safety Light Curtain does not provide a configurable Manual Start/Restart (Latch Output) function. For these applications, this function must be implemented in the external safety monitoring device.
WARNING: · Use of the Banner device for Access or Perimeter Guarding · Failure to observe this warning could result in serious injury or death. · If a Banner device is installed in an application that results in a pass-through hazard (for example, perimeter guarding), either the Banner device System or the Machine Primary Control Elements (MPCEs) of the guarded machine must cause a Latched response following an interruption of the defined area. The reset of this Latched condition may only be achieved by actuating a reset switch that is separate from the normal means of machine cycle initiation. Lockout/Tagout procedures per ANSI Z244.1 may be required, or additional safeguarding, as described by ANSI B11.19 safety requirements or other appropriate standards, must be used if a passthrough hazard can not be eliminated or reduced to an acceptable level of risk.

5.4 Supplemental Safeguarding

As described in Calculating the Safety Distance (Minimum Distance) on page 15, position the S4B such that an individual cannot reach through the defined area and access the hazard point before the machine has stopped.
Additionally, the hazard cannot be accessible by reaching around, under, or over the defined area. To accomplish this, supplemental guarding (mechanical barriers, such as screens or bars), as described by ANSI B11.19 safety requirements or other appropriate standards, must be installed. Access will then be possible only through the defined area of the S4B System or through other safeguarding that prevents access to the hazard.
The mechanical barriers used for this purpose are typically called “hard (fixed) guarding”; there must be no gaps between the hard (fixed) guarding and the defined area. Any openings in the hard (fixed) guarding must comply with the safe opening requirements of ANSI B11.19 or other appropriate standard.

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).

18

www.bannerengineering.com – Tel: + 1 888 373 6767

S4B Safety Light Curtain
Additional supplemental safeguarding may be required to prevent clearance or trapping hazards (for example, a safety mat as an area guard between the robot, the turntable, and the conveyor).
WARNING: · The hazard must be accessible only through the sensing field · Incorrect system installation could result in serious injury or death. · The installation of the S4B must prevent any individual from reaching around, under, over or through the defined area and into the hazard without being detected. · See OSHA CFR 1910.217, ANSI B11.19, and/or ISO 14119, ISO 14120 and ISO 13857 for information on determining safety distances and safe opening sizes for your guarding device. Mechanical barriers (for example, hard (fixed) guarding) or supplemental safeguarding might be required to comply with these requirements.
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. The latch function can be provided by interfacing the S4B OSSD outputs to the machine’s safety-related control system, a safety controller (such as SC10-2roe or XS/SC26-2), or safety module (such as the UM-FA-9A/11A). The system or device providing the latch/reset function must conform to the level of performance required by the risk assessment. In applications requiring Control Reliability and/or ISO 13849-1:2015 Categories 3 or 4 and PL d or e, it is recommended that a monitored manual reset (for example, open- closed-open action), such that a shorted or tied-down button cannot cause a reset be used. The reset switch must be mounted at a location that complies with the warning and guidelines below. If any hazardous areas are not in view from the switch location, additional means of safeguarding must be provided. The switch should be protected from accidental or unintended actuation (for example, through the use of rings or guards). A key-actuated reset switch provides some operator or supervisory control, as the key can be removed from the switch and taken into the guarded area. However, this does not prevent unauthorized or inadvertent resets due to spare keys in the possession of others, or additional personnel entering the guarded area unnoticed. When considering where to locate the reset switch, follow the guidelines below.
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 safeguarded space. Reset switches cannot be accessible from within the safeguarded space. Protect reset switches against unauthorized or inadvertent operation (for example, through the use of rings or guards). If there are any hazardous areas that are not visible from the reset switches, provide additional safeguarding.
All reset switches must be: · Outside the guarded area · Located to allow the switch operator a full, unobstructed, view of the entire guarded area while the reset is performed · Out of reach from within the guarded area · Protected against unauthorized or inadvertent operation (such as through the use of rings or guards).
Important: Resetting a safeguard must not initiate hazardous motion. Safe work procedures require a start-up procedure to be followed and the individual performing the reset to verify that the entire hazardous area is clear of all personnel before each reset of the safeguard is performed. If any area cannot be observed from the reset switch location, additional supplemental safeguarding must be used: at a minimum, visual and audible warnings of machine start-up.

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.
WARNING: · Do not install the system near reflective surfaces · Reflective surfaces could reflect the sensing beam(s) around an object or person within the defined area, preventing detection by the system. Failure to prevent reflection problems results in incomplete guarding and an optical short circuit that could result in serious injury or death. · Do not locate the defined area near a reflective surface. Perform the trip test, as described in the product documentation, to detect such reflection(s).
This reflective surface may result from shiny surfaces or glossy paint on the machine, the workpiece, the work surface, the floor, or the walls. Beams deflected by reflective surfaces are discovered by performing the trip test and the periodic checkout procedures. To eliminate problem reflections:
· If possible, relocate the sensors to move the beams away from the reflective surface(s) (see Figure 5 on page 20), being careful to maintain adequate Safety Distance (Minimum Distance)
· Otherwise, if possible, paint, mask, or roughen the shiny surface to reduce its reflectivity · Where these are not possible (as with a shiny workpiece or machine frame), determine the worst-case resolution (see
Figure 6 on page 20) resulting from the optical short circuit and use the corresponding depth penetration factor (Dpf or C) in the Safety Distance (Minimum Distance) formula (see Calculating the Safety Distance (Minimum Distance) on page 15); or mount the sensors in such a way that the receiver’s field of view and/or the emitter’s spread of light are restricted from the reflective surface · Repeat the trip test (see Trip Test under Initial Checkout Procedure on page 30) to verify these changes have eliminated the problem reflection(s). If the workpiece is especially reflective and comes close to the defined area, perform the trip test with the workpiece in place

To determine the worst-case resolution, select larger test pieces (represented by the light gray circle) and perform a Trip Test. The midpoint between the emitter and receiver may cause the most optical short circuits. The test piece that passes the Trip Test determines the worst-case resolution for this installation.

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.
The use of glass-surface corner mirrors reduces the maximum specified emitter/receiver separation by approximately 8 percent per mirror, as follows:

See the specific mirror datasheet or www.bannerengineering.com for more information.
If mirrors are used, the difference between the angle of incidence from the emitter to the mirror and from the mirror to the receiver must be between 45° and 120°. If placed at a sharper angle, an object in the light screen may deflect beam(s) to the receiver, preventing the object from being detected, also know as false proxing. Angles greater than 120° result in difficult alignment and possible optical short circuits.

WARNING: · Retroreflective Mode Installation · Failure to follow these instructions may create unreliable sensing and may result in serious injury or death.
· Do not install emitters and receivers in retroreflective mode with less than a 45° angle of incidence. Install emitters and receivers at an appropriate angle.

5.6.3 Emitter and Receiver Orientation
The emitter and receiver must be mounted parallel to each other and aligned in a common plane, with both machine interface cable ends pointing in the same direction. Never mount the emitter with its machine interface cable end oriented in the opposite direction of the cable end of the receiver. If this occurs, voids in the light screen may allow objects or personnel to pass through the defined area undetected. The emitter and receiver may be oriented in a vertical or horizontal plane, or at any angle between horizontal and vertical, as long as they are parallel to each other and their cable ends point in the same direction. Verify that the light screen completely covers all access to the hazard point that is not already protected by hard (fixed) guarding or other supplemental guarding.
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.

5.6.4 Installation of Multiple Systems

Whenever two or more S4B emitter and receiver pairs are adjacent to one another, optical crosstalk may take place between the systems.

To minimize optical crosstalk, alternate the positions of the emitters and receivers as shown in Figure 11 on page 24, or alternate scan codes.
When three or more systems are installed in the same plane, optical crosstalk may occur between sensor pairs whose emitter and receiver lenses are oriented in the same direction. In this situation, eliminate optical crosstalk by mounting these sensor pairs exactly in line with each other within one plane, or by adding a mechanical barrier between the pairs as shown in Figure 11 on page 24.

Figure 10. Optical Crosstalk

Emitter 2

Receiver 2

Emitter 1

WARNING: · Adjacent components can synchronize incorrectly · The light curtain’s safety function is reduced when components are not synchronized correctly, creating an unsafe condition that could result in serious injury or death. · When multiple systems are mounted closely together, or where a secondary emitter is in view (within ±5°) and within range of an adjacent receiver, a receiver can synchronize to the signal from the wrong emitter, reducing the safety function of the light curtain.
To further aid in avoiding crosstalk, the sensors feature two selectable scan codes. A receiver set to one scan code will not respond to an emitter set to another code. The emitter and receiver within a system must be set to the same scan code.
Scan codes are set via the switches in the removable DES4E-… cordsets on the emitters and receivers. See Scan Code Selection on page 28 for the switch settings.

5.7 Mounting System Components
5.7.1 Mounting Hardware
After the mechanical layout considerations are addressed, mount the sensors and route the cables. All brackets are ordered separately; no brackets are shipped with the sensors. The quantity of brackets ordered and the placement of those brackets must ensure the unsupported distance (distance between brackets) is less than 900 mm (35.4 in).

24

www.bannerengineering.com – Tel: + 1 888 373 6767

S4B Safety Light Curtain

Mounting the S4BA-MBK-16 Side-Mount Bracket

The S4BA-MBK-16 brackets are ordered separately. Two brackets are included in each kit.

Figure 12. Side-Mount Bracket

· See Sensor Mounting and Mechanical Alignment Verification on page 26 for additional mounting recommendations
· The machine interface connector ends of both sensors must point in the same direction
· The sensors are designed to be mounted with up to 900 mm (35.4 in) of unsupported distance between brackets when they are subject to shock or vibration

Note: Note: It is best to place brackets near the ends of each sensor (not on end caps). Add additional brackets per sensor as needed to meet 900 mm unsupported distance requirement. This means that 300 mm to 900 mm sensors can use two brackets per sensor, while 1050 mm to 1800 mm sensors should use three brackets per sensor.
· See Brackets on page 47 for mounting bracket dimensions
· The M4 bolts, washers, and nuts are user-supplied

Note: Use washers under the screw heads to minimize bracket damage.

1. From a common point of reference (ensuring the calculated minimum safety distance), measure to position the emitter and receiver in the same plane, with their midpoints directly opposite each other.
The connector ends of both sensors must point in the same direction (see Emitter and Receiver Orientation on page 22). 2. Mount the emitter and receiver side brackets to the desired surface with user-supplied M4 bolts, washers, and nuts. Tighten to 2.15 N·m (19 in·lbs). 3. Loosen the M4 clamp screws on the side brackets enough to easily insert a sensor. 4. Insert each sensor in to its respective brackets with the front window facing out of the opening in the front of the bracket.
Note: The sensors need to lightly snap into the brackets. If the sensors will not install easily, loosen the M4 clamp screws to allow the clamps to slide out of the way of the sensor.
5. Position the emitter and receiver windows directly facing each other. 6. Measure from a reference plane, for example, a level building floor, to the same point(s) on the emitter and receiver
to verify their mechanical alignment. Use a carpenter’s level, a plumb bob, or the optional LAT-1 Laser Alignment Tool (see Alignment Aids on page 50) or check the diagonal distances between the sensors, to achieve mechanical alignment. See Sensor Mounting and Mechanical Alignment Verification on page 26. 7. Temporarily tighten all fasteners that allow for adjustment. Final alignment procedures are explained in Initial Checkout Procedure on page 30. 8. After the emitter and receiver alignment is completed, tighten the bracket front M4 clamp screws to 2.15 N·m (19 in·lbs).
Note: Each bracket has two clamp screws. Both clamp screws on every bracket need to be fully tightened to provide sufficient strength to hold the sensor. Do not reposition the sensor when the clamps are mostly or fully tightened. Doing so could damage clamp pads.

6 Electrical Installation and Testing
The following are the main steps to electrically install the S4B components and interface with the guarded machine.
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 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 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.
1. Routing cordsets and making initial electrical connections (see Routing Cordsets on page 28 and Initial Electrical Connections on page 30).
2. Apply power to each emitter/receiver pair (see Initial Electrical Connections on page 30). 3. Perform an Initial Checkout Procedure (see Initial Checkout Procedure on page 30). 4. Make all electrical interface connections to the guarded machine (see Electrical Connections to the Guarded Machine
on page 34). 5. Perform a commissioning checkout procedure (see Commissioning Checkout on page 36).

6.1 Routing Cordsets

Attach the required cordsets to the sensors, and route the sensor cables to the junction box, electrical panel, or other enclosure in which the other safety-related parts of the control system are located. This must be done per local wiring code for low-voltage dc control cables and may require installation of electrical conduit.
See Accessories on page 47 for selection of Banner supplied cables.
The S4B is designed and manufactured to be highly resistant to electrical noise and to operate reliably in industrial settings. However, extreme electrical noise may cause a random Trip condition; in extreme cases, a Lockout is possible.
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.
Sensor cabling and any interconnect wiring should have an insulation temperature rating of at least 90 °C (194 °F).

Note: Emitter and receiver power (current) requirements are accounted for. The above values represent additional current draw that must be accounted for.

Note: Maximum cordset lengths are intended to ensure that adequate power is available to the S4B when the supply is operating at +20 V DC. Values in the previous table are worse case. Contact Banner Engineering if there are any questions.

6.2 Scan Code Selection
The emitter and receiver may be configured to one of two Scan Codes (1 or 2).
A receiver recognizes light only from an emitter with the same scan code. Both the emitter and its corresponding receiver must have the same scan code setting. The scan code must be configured with power off because the DES4E-.. RD to M12 cordset assemblies must be removed from the units.

28

www.bannerengineering.com – Tel: + 1 888 373 6767

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.
Figure 14. Remove the Cordset
2. Flip the cordset over to see the two switches.

S4B Safety Light Curtain

6.3 Initial Electrical Connections
WARNING: · Risk of electric shock · Use extreme caution to avoid electrical shock. Serious injury or death could result. · Always disconnect power from the safety system (for example, device, module, interfacing, etc.), guarded machine, and/or the machine being controlled before making any connections or replacing any component. Lockout/tagout procedures might be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, or the applicable standard for controlling hazardous energy. · Make no more connections to the device or system than are described in this manual. Electrical installation and wiring must be made by a Qualified Person 4 and must comply with the applicable electrical standards and wiring codes, such as the NEC (National Electrical Code), NFPA 79, or IEC 60204-1, and all applicable local standards and codes.
Lockout/tagout procedures may be required (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard for controlling hazardous energy). Make the electrical connections in the order described in this section. Do not remove end-caps; no internal connections are to be made. 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. In addition to providing similar cabling, this wiring scheme is advantageous during installation, wiring, and troubleshooting.
Receiver Cordset Do not connect any wires to the machine control circuits (OSSD outputs) at this time.

6.4 Initial Checkout Procedure
The initial checkout procedure must be performed by a Qualified Person. It must be performed only after configuring the System and after connecting the components. Perform this procedure to:
· Ensure proper installation when the System is first installed · Ensure proper System function whenever any maintenance or modification is performed on the System or on the
machinery that is guarded by the System.
6.4.1 Configuring the System for Initial Checkout
For the initial checkout, the S4B System must be checked without power available to the guarded machine. Final interface connections to the guarded machine cannot take place until the light screen system has been checked out. This may require lockout/tagout procedures (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard for controlling hazardous energy). The OSSD connections will be made after the initial checkout procedure has been successfully completed. Verify that:
· Power has been removed from (or is not available to) the guarded machine and its controls or actuators · The machine control circuit or the Safety/Interface Module is not connected to the OSSD outputs at this time
(permanent connections will be made later)
6.4.2 Apply Initial Power to the S4B System
1. Inspect the area near the light screen for reflective surfaces, including work pieces and the guarded machine. Reflective surfaces may cause light beams to reflect around a person in the light screen, preventing the person from being detected and not stopping the machine motion (see Adjacent Reflective Surfaces on page 20).
2. Eliminate the reflective surfaces as much possible by relocating, painting, masking, or roughening them. Remaining problem reflections will become apparent during the trip test.
4 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.

S4B Safety Light Curtain
3. Verify that power is removed from the S4B System and from the guarded machine and that the OSSD safety outputs are not connected.
4. Remove all obstructions from the light screen. 5. With the power to the guarded machine off, connect +24 V DC (brown wire) and 0 V DC (blue wire) on both the
emitter and receiver cables to a SELV-rated power supply (see Wiring Diagrams on page 38). 6. Power up the S4B System only. 7. Verify that the input power is present to both the emitter and the receiver. At least one indicator on both the emitter
and the receiver should be on and the start-up sequence should cycle. 8. Watch both the emitter and the receiver Status indicators and the receiver Zone indicators to determine the light
screen alignment status. · Emitter Lockout Condition–the emitter’s red Status indicator is single-flashing and the receiver’s red Status
indicator is on. Proceed to Troubleshooting on page 42 for diagnostic information. · Receiver Lockout Condition –the receiver Status indicator is single-flashing red. Proceed to Troubleshooting
on page 42 for diagnostic information. · Normal Operating Mode (emitter)–The green Status indicator is on. · Clear (Run) Condition (receiver)–The green Status indicator is on. All green Zone indicators are on. · A Blocked Condition (receiver)–The red Status indicator is on and one or more red Zone indicator(s) are on,
identifying the location of the blocked beams. Proceed to Optically Align the System Components on page 31.
Note: If beam 1 is blocked, Zone indicator 1 is red and all others are off. Beam 1 provides the synchronization signal.
See Operating Features on page 10 for indicator and display information.
6.4.3 Optically Align the System Components
To verify the optimal alignment, adjust the sensor rotation with the power on and follow these steps.
WARNING: · Hazard exposure · Failure to follow these instructions could result in serious injury or death. · Verify that no individuals are exposed to any hazard if the output signal switching device (OSSD) outputs turn on when the emitter and receiver become aligned.
Before beginning, verify the sensor mounting. 1. Verify that the emitter and the receiver are pointed squarely at each other. The sensor face must be perpendicular to the optical axis.

If the Channel #1 beam is not aligned, the Status and Zone 1 indicators are red and Zone indicators 2­3 are off.
2. If the green Status indicator is on, go to the next step. If not, rotate each sensor (one at a time) left and right until the green Status indicator is on. (As the sensor rotates out of alignment, the red Status indicator turns on). As more beams are aligned, the Zone indicators turn from red to green.

3. Optimize alignment and maximize excess gain.

S4B Safety Light Curtain

a) Slightly loosen the sensor mounting screws. b) Rotate one sensor left and right, noting the positions in each arc where the Status indicators turn red (Blocked
condition) or a zone indicator turns yellow (weak beam strength); repeat with the other sensor. c) Center each sensor between those two positions. d) Tighten the mounting screws, making sure to maintain the positioning as the screws are tightened. If at any time the red Status indicator begins to flash, the System has entered a Lockout condition. See Troubleshooting on page 42 for further information.
Flashing
6.4.4 Optical Alignment Procedure with Mirrors
S4B 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 reduced when using mirrors; see Use of Corner Mirrors, under Mechanical Installation Considerations on page 15. During any adjustments, allow only one individual to adjust any one item at any one time. In addition to the standard optical alignment procedure, verify:
1. The emitter, receiver, and all mirrors are level and plumb. 2. The middle of the defined area and the center point of the mirrors are approximately the same distance from a
common reference point, such as the same height above a level floor. 3. There are equal amounts of mirror surface above and below the defined area such that the optical beams are not
passing below or above the mirror.

Component 3 (Mirror)

Component 1 (Emitter)

Component 4 (Receiver)

6.4.5 Conduct a Trip Test
After optimizing the optical alignment and configuring fixed blanking and/or reduced resolution (if applicable), perform a trip test to verify the detection capability of the S4B System.
This test also verifies correct sensor orientation, identifies optical short circuits, and verifies the expected resolution for applications using reduced resolution. After the installation has passed the trip test, the safety outputs may be connected and the commissioning checkout may be performed (initial installations only).

1. Select the proper test piece, ordered separately.
For 30 mm resolution models: use the 30 mm (0.94 in ) diameter model STP-14. 2. Verify that the System is in run mode, the green Status indicator is on, and all Zone indicators are green. 3. Pass the specified test piece through the defined area in three paths: near the emitter, near the receiver, and midway
between the emitter and receiver.

4. During each pass, while the test piece is interrupting the defined area, at least one Zone indicator must be red. The red Zone indicator must change with the position of the test piece within the defined area. The Status indicator must turn red and remain red for as long as the test piece remains in the defined area. If not, the installation has failed the trip test.
If all Zone indicators turn green or fail to follow the position of the test piece while it is within the defined area, the installation has failed the trip test. Check for correct sensor orientation or reflective surfaces. Do not continue until the situation is corrected.
When the test piece is removed from the defined area, the green Status indicator must turn on.
WARNING: · Trip test failure · Using a system that has failed a trip test can result in serious bodily injury or death. If the trip test has failed, the system might not stop dangerous machine motion when a person or object enters the sensing field. · Do not attempt to use the system if the system does not respond properly to the trip test.
5. If mirrors are used in the application: Test the defined area on each leg of the sensing path (for example, emitter to mirror, between mirror and receiver).

6. If the S4B System passes all checks during the trip test, go on to Electrical Connections to the Guarded Machine on page 34.
6.5 Electrical Connections to the Guarded Machine
Verify that power has been removed from the S4B and the guarded machine. Make the permanent electrical connections as required by each individual application. Lockout/tagout procedures may be required (refer to OSHA 1910.147, ANSI Z244-1, ISO 14118, or the appropriate standard for controlling hazardous energy). Follow relevant electrical standards and wiring codes, such as the NEC, NFPA79 or IEC 60204-1. Supply power should already be connected. The S4B must also have been aligned and passed the Initial Checkout, as described in Initial Checkout Procedure on page 30. The final connections to be made or verified are:
· OSSD outputs
WARNING: · Risk of electric shock · Failure to follow these instructions could result in serious injury or death. · Disconnect or turn off power before installing, removing, or servicing the device. · Install and connect the device in accordance with the National Electrical Code (NEC) and any applicable local code requirements and supply the device with an appropriate fuse box or circuit breaker (see Specifications).
6.5.1 Protective Stop (Safety Stop) Circuits
A protective stop (safety stop) allows for an orderly cessation of motion for safeguarding purposes, which results in a stop of motion and removal of power from the Machine Primary Control Elements (MPCE) (assuming this does not create additional hazards). A protective stop circuit typically comprises a minimum of two normally open contacts from forced-guided, mechanically linked relays, which are monitored through External Device Monitoring (EDM) to detect certain failures, to prevent the loss of the safety function. Such a circuit can be described as a “safe switching point”. Typically, protective stop circuits are either single channel, which is a series connection of at least two normally open contacts; or dual-channel, which is a separate connection of two normally open contacts. In either method, the safety function relies on the use of redundant contacts to control a single hazard. If one contact fails ON, the second contact arrests the hazards and prevents the next cycle from occurring. The interfacing of the protective stop circuits must be accomplished so that the safety function cannot be suspended, overridden, or defeated, unless accomplished in a manner of the same or greater degree of safety as the machine’s safety related control system that includes the S4B. A Banner XS26-2 Safety Controller with XS1ro or XS2ro Relay Expansion Module, Banner SC10-2roe Safety Controller, or Banner UM-FA-xA Universal Safety Module provides a series connection of redundant contacts that form protective stop circuits for use in either single-channel or dual-channel control.
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. Final Switching Devices (FSDs) typically accomplish this when the OSSDs go to an OFF state. Refer to the output specifications in the Receiver Specifications and these warnings before making OSSD output connections and interfacing the S4B to the machine.

34

S4B Safety Light Curtain

WARNING:
· Interfacing both output signal switching devices (OSSD)
· Failure to follow these instructions could result in serious injury or death.
· Unless the same degree of safety is maintained, never wire an intermediate device(s) (PLC, PES, PC) between the safety module outputs and the master stop control element it switches such that a failure causes a loss of the safety stop command or the failure allows the safety function to be suspended, overridden, or defeated.
· Connect both OSSD outputs to the machine control so that the machine’s safety-related control system interrupts the circuit to the machine primary control element(s), resulting in a nonhazardous condition.

WARNING: · OSSD Interfacing · Failure to properly interface the OSSD Outputs to the guarded machine could result in serious injury or death. · To ensure proper operation, the Banner device output parameters and machine input parameters must be considered when interfacing the Banner device OSSD outputs to machine inputs. Design machine control circuitry so that all of the following are true:
The maximum load resistance value is not exceeded.
The maximum specified OSSD OFF-state voltage does not result in an ON condition.

External device monitoring (EDM) is a function used to monitor the state of the external, positively guided (mechanically linked) machine control contacts (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. Examples of appropriate external safety monitoring devices include Banner XS/SC26 Safety Controllers, SC10-2roe Safety Controller, Banner UM-FA-9A and UM-FA-11A Universal Input Safety Modules, and Safety PLCs.

WARNING: · The S4B does not have external device monitoring (EDM). · If EDM is required for the application, it must be implemented in the external control.

6.5.2 Preparing for System Operation
After the initial trip test has been accomplished, and the OSSD safety outputs connections have been made to the external control device, the S4B is ready for testing in combination with the guarded machine.
The operation of the S4B with the guarded machine must be verified before the combined System and machine may be put into service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure. See Commissioning Checkout on page 36.

6.5.3 Sensor Interchangeability
The figures and table below illustrate a wiring option that provides sensor interchangeability (or swapability)–the ability to install either sensor at either QD connection.
The resulting installation provides the ability to swap the emitter and receiver position. This wiring option provides advantages during installation, wiring, and troubleshooting.
To use this option, connect all emitter wires in parallel (color-for-color) to the receiver cable via individual wires or the CSB.. splitter cordset.
Model CSB.. splitter cordsets and DEE2R.. double-ended cordsets allow easy interconnection between an S4B receiver and emitter, providing a single homerun cordset.

6.5.4 Commissioning Checkout
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).

WARNING: · Do not use the system until the checkouts are verified · Attempts to use the guarded/controlled machine before these checks are verified could result in serious injury or death. · If all these checks cannot be verified, do not attempt to use the safety system that includes the Banner device and the guarded/controlled machine until the defect or problem has been corrected.
A Qualified Person must perform the procedure. Checkout results should be recorded and kept on or near the guarded machine as required by applicable standards.
To prepare the System for this checkout:
1. Examine the guarded machine to verify that it is of a type and design compatible with the S4B System. See Examples: Inappropriate Applications on page 10 for a list of misapplications.
2. Verify that the S4B is configured for the intended application.

36

www.bannerengineering.com – Tel: + 1 888 373 6767

S4B Safety Light Curtain
3. Verify that the safety distance (minimum distance) from the closest danger point of the guarded machine to the defined area is not less than the calculated distance, per Calculating the Safety Distance (Minimum Distance) on page 15.
4. Verify that: a) Access to any dangerous parts of the guarded machine is not possible from any direction not protected by the S4B System, hard (fixed) guarding, or supplemental safeguarding, and b) It is not possible for a person to stand between the defined area and the dangerous parts of the machine, or c) Supplemental safeguarding and hard (fixed) guarding, as described by the appropriate safety standards, are in place and functioning properly in any space (between the defined area and any hazard) which is large enough to allow a person to stand undetected by the S4B.
5. If used, verify that all reset switches are mounted outside and in full view of the guarded area, out of reach of anyone inside the guarded area, and that means of preventing inadvertent use is in place.
6. Examine the electrical wiring connections between the S4B OSSD outputs and the guarded machine’s control elements to verify that the wiring meets the requirements stated in Electrical Connections to the Guarded Machine on page 34.
7. Inspect the area near the defined area (including work pieces and the guarded machine) for reflective surfaces (see Adjacent Reflective Surfaces on page 20). Remove the reflective surfaces, if possible, by relocating them, painting, masking or roughening them. Remaining problem reflections will become apparent during the Trip Test.
8. Verify that power to the guarded machine is off. Remove all obstructions from the defined area. Apply power to the S4B System.
9. Observe the Status indicators and Diagnostic Display: · Lockout: Red Status flashing; all others off · Blocked: Red Status on; one or more red Zone indicators on · Clear: Green Status on; all green Zone indicators on
10. A Blocked condition indicates that one or more of the beams is misaligned or interrupted. See Optically Align the System Components on page 31 to correct this situation.
11. After the green Status indicator is on, perform the trip test (Conduct a Trip Test on page 32) on each sensing field to verify proper System operation and to detect possible optical short circuits or reflection problems. Do not continue until the S4B passes the trip test.
Important: Do not expose any individual to any hazard during the following checks.
WARNING: · Clear the guarded area before applying power or resetting the system · Failure to clear the guarded area before applying power could result in serious injury or death. · Verify that the guarded area is clear of personnel and any unwanted materials before applying power to the guarded machine or before resetting the system.
12. Apply power to the guarded machine and verify that the machine does not start up. 13. Interrupt (block) the defined area with the test piece and verify it is not possible for the guarded machine to be put into
motion while the beam(s) is blocked. 14. Initiate machine motion of the guarded machine and, while it is moving, use the test piece to block the defined area.
Do not attempt to insert the test piece into the dangerous parts of the machine. Upon blocking any beam, the dangerous parts of the machine must come to a stop with no apparent delay. 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. 17. Test the machine stopping response time, using an instrument designed for that purpose, to verify that it is the same or less than the overall system response time specified by the machine manufacturer.
Do not continue operation until the entire checkout procedure is complete and all problems are corrected.

S4B Safety Light Curtain
7 System Operation
7.1 Security Protocol
Certain procedures for installing, maintaining, and operating the S4B 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 system resets and the specified checkout procedures on the S4B. The Designated Person is empowered to:
· Perform manual resets and hold possession of the reset key · Perform the Daily Checkout Procedure 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 S4B 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 S4B System · Perform all checkout procedures · Make changes to the internal configuration settings · Reset the System following a Lockout condition
7.2 Normal Operation

7.2.1 System Power-Up
When power is applied, each sensor conducts self-tests to detect critical internal faults, determine configuration settings, and prepare the S4B for operation. If either sensor detects a critical fault, scanning ceases, the receiver outputs remain Off and diagnostic information displays. If no faults are detected, the S4B automatically enters Alignment mode, and the receiver looks for an optical sync pattern from the emitter. 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). If all the beams then become clear, the receiver outputs come back On. No resets are needed. All required machine control resets are provided by the machine control circuit. Internal Faults (Lockouts): If either sensor detects a critical fault, scanning ceases, the receiver outputs turn Off and diagnostic information displays. See Troubleshooting on page 42 for resolution of error/fault conditions.
7.2.3 Emitter Indicators
A single Status indicator shows whether power is applied, and whether the emitter is in Run mode or a Lockout condition. Two Scan Code indicators show the scan code assigned to the emitter.

Emitter Operating Status Power-up
Run Mode Lockout

Status Indicator Red on for several seconds
Green Flashing Red

7.2.4 Receiver Indicators

A single Status indicator shows when the OSSD outputs are on (green) or off (red), or the System is in a Lockout condition (flashing red).
Zone indicators show whether a section of the defined area is aligned and clear, is blocked and/or misaligned, or is a section that has a channel with a weak beam strength. All models have three Zone indicators, each of which indicates Blocked/Clear/ Weak Beam Strength conditions for approximately 1/3 of the total light screen.

7.3 Periodic Checkout Requirements
To ensure continued reliable operation, the System must be checked out periodically. Banner Engineering highly recommends performing the System checkouts as described below. However, a Qualified Person should evaluate these recommendations, based on the specific application and the results of a machine risk assessment, to determine the appropriate content and frequency of checkouts.
At every shift change, power-up, and machine setup change, the Daily Checkout should be performed; this checkout may be performed by a Designated or Qualified Person.
Semi-annually, the System and its interface to the guarded machine should be thoroughly checked out; this checkout must be performed by a Qualified Person (see Schedule of Checkouts on page 44). A copy of these test results should be posted on or near the machine.
Whenever changes are made to the System (either a new configuration of the S4B System or changes to the machine), perform the Commissioning Checkout (see Commissioning Checkout on page 36).
Note: Verify Proper Operation
The S4B can operate as it is designed only if it and the guarded machine are operating properly, both separately and together. It is the user’s responsibility to verify this, on a regular basis, as instructed in Schedule of Checkouts on page 44. Failure to correct such problems can result in an increased risk of harm.
Before the System is put back into service, verify that the S4B System and the guarded machine perform exactly as outlined in the checkout procedures and any problem(s) are found and corrected.

5 If beam 1 is blocked, Zone indicators 2­3 will be Off, because beam 1 provides the synchronization signal for all the beams.

8 Troubleshooting

8.1 Lockout Conditions

A Lockout condition causes both S4B OSSD outputs to turn off or remain off, sending a stop signal to the guarded machine. Each sensor provides diagnostic error codes to identify the cause(s) of lockouts (see Troubleshooting on page 42). The following tables indicate a sensor lockout condition:

Emitter Lockout Conditions

Status indicator

Flashing Red

Receiver Lockout Conditions Status indicator Zone indicators

Flashing Red See Receiver Error Codes on page 42

To recover from a Lockout condition, correct all errors and cycle power to the device.

8.2 Receiver Error Codes

Indicators
Flashing

Error Description
Output Error caused by: · one or both outputs being shorted to a power supply (high or low) · by shorting OSSD 1 to OSSD 2 · by an overload (greater than 0.5 A)

Appropriate Action
· Disconnect the OSSD loads and reset the receiver. · If the error clears, the problem is in the OSSD load(s) or in the
load wiring. · If the error continues with no load connected, replace the
receiver.

Flashing

Receiver Error occurs because of excessive electrical noise or an internal failure

· Perform a reset per Checkout Procedures: Shift and Daily Checkout Procedure.
· If the error clears, perform a Daily Checkout procedure (per Checkout Procedures: Shift and Daily Checkout Procedure; Daily Checkout Card) and if the System checks out, resume operation. If the System fails the Daily Checkout procedure, replace the receiver.
· If the error clears, check the external connections and configuration settings.
· If the error continues, replace the receiver.

8.3 Electrical and Optical Noise
The S4B is designed and manufactured to be highly resistant to electrical and optical noise and to operate reliably in industrial settings. However, serious electrical and/or optical noise may cause a random nuisance trip. In extreme electrical noise cases, a Lockout is possible. To minimize the effects of transitory noise, the S4B responds to noise only if the noise is detected on multiple consecutive scans. If random nuisance trips occur, check the following:
· Optical interference from adjacent light screens or other photoelectrics · Sensor input or output wires routed too close to noisy wiring
8.3.1 Checking for Sources of Electrical Noise
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 highvoltage wires.
1. Use the Banner model BT-1 Beam Tracker Alignment Aid (see Accessories on page 47) to detect electrical transient spikes and surges.
2. Cover the lens of the BT-1 with electrical tape to block optical light from entering the receiver lens.

42

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.
5. Install proper transient suppression across the load to reduce the noise.
8.3.2 Check for Sources of Optical Noise
1. Turn off the emitter or completely block the emitter. 2. Press the RCV button on the Banner BT-1 Beam Tracker Alignment Aid and move it across the full length of the
receiver’s sensing window to check for light at the receiver. 3. If the BT-1’s indicator lights, check for emitted light from other sources (other safety light screens, grids or points, or
standard photoelectric sensors).

9 Checkout Procedures
This section lists the schedule of checkout procedures and describes where each procedure is documented. Checkouts must be performed as described. 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. This will generally be determined by a risk assessment, such as the one contained in ANSI B11.0. The result of the risk assessment will drive the frequency and content of the periodic checkout procedures and must be followed.
