Target machine
2
• The SL-V has not undergone the model certification examination in accordance with Article 44-2 of the Japanese Industrial Safety and Health Law. The SL-V, therefore, cannot be used in Japan as a “Safety Device for Press and Shearing machines” as established in Article 42 of that law. The machine on which the SL-V is to be installed must be susceptible to an emergency stop at all
• operating points during its operation cycle. Do not use the SL-V for machines with irregular stop times.
• Do not use the SL-V for power presses equipped with full-revolution clutches.
• The SL-V cannot be used as a PSDI because it does not fulfill the requirements of OSHA
1910.217(h). Refer to OSHA 1910.217 for the PSDI mode.
• Do not use the SL-V to control (stop forward motion, etc.) trains, cars and other transporta­tion vehicles, aircraft, equipment for use in space, medical devices, or nuclear power gener­ation systems.
• The SL-V is designed to protect the people or objects from going into/approaching detec­tion zone against machine’s hazard or hazardous zone. It cannot provide protection against objects or materials that are expelled from the machine’s hazard or hazardous zone, so you must establish additional safety measures such as installing safeguards when there is the possibility of such projectiles.
SL-V-M-NO0-E
Installation
Danger
• The SL-V must be installed only after ensuring the minimum safety distance between the SL-V and the hazardous zone or hazard as established by the applicable regulations in the country or region in which the SL-V is used. (e.g.EN ISO13855(ISO 13855)in EU countries)
• Choose locations for the installation of the SL-V transmitters and receivers so that they are not subject to the effects of light reflected from glossy surfaces in the area.
• Correct operation and detection is not possible if the receiver has a different number of beam axes from that of the transmitter. You must verify that the number of beam axes is the same between the transmitter and the receiver when installing the SL-V.
• Correct operation and detection is not possible if the receiver has a different beam axis spacing (detection capability) from that of the transmitter. You must verify that the beam axis spacing (detection capability) is the same between the transmitter and the receiver when installing the SL-V.
• The SL-V must be installed so that the machine operator is able to go into or approach the hazardous zone or hazards only by passing through the detection zone of the SL-V. Strictly avoid installation that allows the machine operator or a part of the machine operator's body to go into or approach the hazardous zone or hazards without passing through the detec­tion zone of the SL-V or to remain in a position between the detection zone of the SL-V and the hazardous zone or hazard. In case where you install the SL-V units in series (series connection), you always must check the installation carefully whether you follow this warn­ing, especially after installation and maintenance. Even if you forget to install the SL-V unit to be connected in series, or if the series connec­tion cable is disconnected, the SL-V does not detect such a missing or disconnection. (It means the SL-V starts the normal operation.) This causes a dangerous situation because there is no protection at the area to be protected.
• You must always perform the pre-check tests after installing the SL-V in accordance with the pre-check test procedures, such as items specified in this user’s manual, in order to ver­ify that the test pieces can be detected in all of the detection zones.
• Interlock reset mechanisms (such as switches) must be installed so that the whole hazard­ous zone can be checked by the responsible personnel. Interlock reset mechanisms should not be accessible from within the hazardous zone.
• Muting is a function to allow a temporary automatic suspension of the SL-V safety functions while the SL-V is receiving a signal from muting devices (such as sensors or switches). Therefore, additional safety measures are required for the machine on which the SL-V is installed in order to ensure safety while the muting is activated.
• Muting devices, the installation of those devices and the procedure to activate the muting function must fulfill the conditions specified in this user’s manual and the requirements of the laws, rules, regulations and standards in the country or region in which the SL-V and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.
• When you install muting devices (such as sensors or switches) for muting, the following conditions must be fulfilled.
(1) Muting devices must be installed so that the muting cannot be activated if the
hazardous zone of the machine is in an unsafe condition or cycle.
(2) Muting devices must be installed so that the muting cannot be activated even if the
personnel is accidentally approaching the detection zone of the SL-V.
The muting device must be installed such that only responsible personnel have access to that device to change its installation or orientation. Special tools must be required to ensure that only responsible personnel are capable of installation, orientation or change of muting device.
• Only the responsible personnel may be allowed to install or wire the devices to activate the muting function.

dards in the country or region in which the SL-V is used if you apply the muting function. It depends on the machine application and/or the result of your risk assessment. If it is neces­sary for you to provide the muting lamp, you must fulfill the requirements because you are fully responsible for installation of muting lamp.
When the reduced resolution function is applied, the detection capability varies according to your configuration. Make sure to accurately calculate the safety distance according to the detection capability, and install the SL-V at a distance greater than or equal to the minimum safety distance away from the hazardous zone or hazard. The installation of additional safety measures, such as a safeguarding, may be required if the detection capability varies due to the configuration of the reduced resolution function. On your own responsibility, you must perform the risk assessment based on your configuration of the reduced resolution function in order to reduce the risk.
• When the fixed blanking function is applied, a hazardous clearance that is not protected by the SL-V may be generated between the obstacle and the SL-V. You must install an addi­tional safety measure such as a safeguard for this clearance.
• The override is a function to allow a temporary manual suspension of the safety functions of the SL-V. Therefore, additional safety measures are required for the whole machine system on which the SL-V is installed in order to ensure safety while the override is activated.
• The override devices, the installation of those devices and the procedures to activate the override must fulfill the conditions specified in this manual as well as the requirements of the laws, rules, regulations and standards in the country or region in which the SL-V and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.
• The override devices, which are used for activation of override, must be manual operating device. When installing the devices to activate the override, those devices must be installed so that the whole hazardous zone can be checked by the responsible personnel and so that it is not possible for machine operators to operate those devices in the hazardous zone.
• The installation of the indication for override may be required by the laws, rules, regulations, and standards in the country or region in which the SL-V is used if you apply the override function. It depends on the machine application and/or the result of your risk assessment. If it is necessary for you to provide the indication for override, you must fulfill the requirements because you are fully responsible for installation of the indication for override.
• The customer is fully responsible for complying with the requirements for the muting and/or override. Those who use muting and/or override must fulfill all of the requirements related to muting and/or override. KEYENCE accepts NO responsibility or NO liability for any damage or any injury due to the unauthorized installation, usage or maintenance, which are not specified in this user’s manual, and/or due to noncompliance with the laws, rules, regula­tions and standards in the country or region in which the SL-V is used.
• Securely tighten mounting brackets and cable connectors used for the installation of the SL­V in accordance with the torque values specified in this user’s manual.
Circuit design and wiring
4
• Always turn off the power to the SL-V when performing electrical wiring.
• You must fulfill the electrical standards and regulations in the country or region in which the SL-V is being used when you perform the electrical wiring.
• To avoid the risk of electric shock, do not connect any of the SL-V inputs to DC power sources outside of the range of 24 V DC + 10% or to any AC power source.
• To avoid the risk of electric shock, be sure that the hazardous voltage is isolated from all wiring of the SL-V with reinforced insulation or double insulation.
SL-V-M-NO0-E
• In order to fulfill the requirements in IEC61496-1, UL61496-1, EN61496-1 and UL508, power supply for the SL-V must fulfill the conditions listed below.
(a) A rated output voltage of 24 V DC (SELV, Overvoltage Category II) within +10% and -20%. (b) Double insulation or reinforced insulation between the primary and secondary circuits. (c) Output holding time of 20 ms or more. (d) A power supply must fulfill the requirements of the electrical safety and electromagnetic
compatibility (EMC) regulations or standards in all countries and/or regions where the SL-V is used.
(e) A secondary circuit of power supply (output) must fulfill the requirements for Class 2
Circuits or Limited Voltage/Current Circuits specified in UL508, if the SL-V is used in the United States or Canada.
• Do not install the electric wiring of the SL-V together with or in parallel with high-voltage electrical or power lines.
• Both OSSD outputs provided on the SL-V must be used to establish a safety-related machine control system. Establishing a safety-related machine control system with just one of the OSSD outputs cannot stop the machine due to an OSSD output malfunction and may result in significant harm to the machine operators, including serious injury or death.
When using a PNP output type cable, do not cause short-circuit between the OSSD and +24V. Otherwise, the OSSDs keep staying at the ON-state and it causes a dangerous situation.
When using a PNP output type cable, be sure to connect the load between the OSSD and 0V to avoid a dangerous situation. If the load is incorrectly connected between the OSSD and +24V, the logic of the OSSD operation will be reversed and the OSSD will change to an ON state when the SL-V detects the interruption in the detection zone. This is a dangerous situation.
• When using NPN output type cables, do not cause short-circuit between the OSSD and 0V. Otherwise, the OSSDs keep staying at the ON-state and it causes a dangerous situation.
When using an NPN output type cable, be sure to connect the load between the OSSD and +24V to avoid a dangerous situation. If the load is incorrectly connected between the OSSD and 0V, the logic of the OSSD operation will be reversed and the OSSD will change to an ON state when the SL-V detects the interruption in the detection zone. This is a dangerous situation.
• In case of wiring, regardless of PNP or NPN output type cables, you must fulfill the require­ments of Clause 9.4.3 in IEC60204-1: 2005 in order for the protection against maloperation due to earth fault.
• The Alert output, AUX output, Clear/Blocked Output, state information output and interlock­reset-ready output are not allowed to be used as safety outputs for safety-related machine control systems. Usage of these functions as safety outputs may result in a significant harm to the machine operators, including serious injury or death.
• The wait input is not allowed to be connected to the output from any components compris­ing a part of the safety-related machine control system. If the wait input is connected to the output of a safety component it may result in a significant harm to the machine operators, including serious injury or death.
• The transmitter and receiver cables must be within the lengths specified in this user’s man­ual. Usage of cables longer than the specified length may cause the improper operation of safety functions and may cause a dangerous situation.

Testing and maintenance

• You must always perform the pre-check test in accordance with the pre-check test procedures, after maintenance, adjustment or alignment of the target machine or the SL-V and before the machine startup.
• If the SL-V does not operate properly when you perform pre-check test in accordance with the pre­check test procedures specified in this user’s manual, do not operate the machine.
• You must periodically examine the machine to verify that all brakes, other stop mechanisms, and con­trol devices operate reliably and correctly in addition to checking the SL-V.
• The responsible personnel must perform maintenance procedures as specified in this user’s manual to ensure safety to the machine and SL-V.

Cables

• There are two types of cable: simple function type and multi-function type. The type of cable used deter­mines the function that can be used. (The number of conductors is different from each other.) There­fore, the two types of cables cannot be mixed at the same time. Make sure to use the appropriate type of cable for your applications.
See "Functions and Features" (page 2-1). See "Cable Connections" (page 3-11).
• Cables with different output types cannot be combined. Be sure to match the PNP or NPN output type especially when using the unit connection cable (for extension).

1-6
When using the unit connection cable, junction cable and extension cable together, the sum of the length for all the cables must be 30 m or less. This limitation is applicable to each unit, transmitter and receiver, respectively. Since up to 3 of the SL-V units can be connected in series, up to 2 sets of series connection cables are possible. Two sets of the SL-VS10 cables (cable length: 10 m) can be used. In this case, the sum length of all types of cables, including the series connection cable, must be 50 m or less. This limi­tation is also applicable to each unit, transmitter and receiver, respectively.
Cables must be within the lengths specified. Failure to follow this specification may cause improper operation of safety function, and may cause a dangerous situation.

Before Use
• To mount the protection bar to the SL-V, standard mounting bracket A (OP-42347), B (OP-42348), C (OP-42349), or J (OP-83180) is required.
• The bar and the standard mounting bracket are fixed with the hexagon socket bolts, so the angle of the mounting bracket or the bar cannot be adjusted. However, the angle of the SL-V and the mounting bracket can be adjusted for beam axis adjustment.
• The protection bar can be mounted to the back or side of the SL-V. Select an appropriate intermediate support for the protection bar based on the mounting method.
• Install the unit at the angle shown in the following figure so that the protection bar or the intermediate support bracket does not block the beam axes of the SL-V.

Front protection cover and dimmer filter

KEYENCE can provide the front protection cover to protect the surface of the SL-V and also provide the dimmer filter to shorten the operating distance. Since these are optional, please contact your nearest KEYENCE office for further information.

SL-V Configurator (SL-VH1S)

When the SL-V Configurator is used, the following setting changes and functions are available.
Items Description Refer to page
Muting function
Muting bank function
Override function You can change the override condition. 2-45
Interlock function
Fixed blanking function
You can select the beam axes to be muted. The muting conditions can also be changed. You can change the setting whether or not to use the Muting bank function.
When the muting bank function is used, the override function is disabled. Set the interlock function with the SL-V Configurator because setting of the interlock function with wiring is disabled.
The Interlock function enables OSSD to hold the OFF-state if no interruptions are present in the detection zone upon startup (when the power turns on or the lockout error condition is terminated by the reset input) or upon restart (when the SL-V is interrupted and the OSSD becomes the OFF-state). This state is called "interlock ". To recover from the interlock condition, the reset input must be switched ON to OFF while no interruptions are present in the detection zone. Automatic or manual can be selected individually for start and restart.
Automatic start mode : The OSSD automatically enters the ON-state when
Manual start mode : Enters interlock condition upon startup. Automatic reset mode :
Manual reset mode : Enters interlock condition upon restart.
This function is enabled only for the specified beam axes. The OSSD can hold the ON-state even when an interruption is present in the area. A desired area can be set as an effective zone of this function on a pair of transmitter and the receiver as well as on the all beam axes including the SL-V connected in series. The area where this function is enabled can be set as desired not only between a transmitter-receiver pair, but also on all the beam axes including the SL-V connected in series.
no interruptions are present in the detection zone.
The OSSD automatically returns to the ON-state when no interruptions are present in the detection zone.

Before Use
You can create the configuration on the SL-V Configurator. If you upload or download the configuration to or from the SL-V, you must connect the computer to the SL-V.
The SL-V that must be connected to the computer for configuration is only receiver on the main unit.
• The SL-V1UB, USB 1.1-compatible USB cable (supplied with the SL-V1UB) and the SL-V unit connection cable are required for connection between the SL-V and the computer.
• The main unit must be a Ver.3 if you want to configure something through the SL-V Configurator. In this case, the sub unit is not necessary to be Ver.3.
• The SL-VHS Series can not be used as the main unit.
• The OSSD goes to the OFF-state while the SL-V is connected to the SL-V1UB. You must disconnect the SL-V1UB from the SL-V after uploading or downloading the configuration.

Beam center-line : An optical path joining the optical center of the emitting element on the transmitter to
the optical center of the corresponding receiving element on the receiver. the SL-V must be installed so that the beam center-line mark on the transmitter and that on the
receiver face one another and are located at the same height. Detection height : The height from the top beam center-line to the bottom beam center-line (length). Protection height : An object approaching the detection zone from the top of the detection height is first
detected at point A, which is the distance of the detection capability from the top of
the detection height. The equivalent position on the bottom is called point B. The
height from the top edge of the specified detection capability that exists at point A to
the bottom edge of the specified detection capability that exists at point B is called a
"protection height".
The following calculation formula can be defined: Protection height = "Detection height" + 2 x "the specified detection capability"–"beam
axis diameter".
* Refer to the following diagram for an explanation of beam center-line, detection height and protection height.

Detection zone: The zone in which the specified detection capability can be detected. The detection zone
of the SL-V indicates a square area formed with the detection height and the operating distance. When a part or whole of the specified detection capability is present in this area, the light of the SL-V is blocked, and then the OSSD goes to OFF state.
Protection zone: The square area formed with the protection height and the operating distance, which
is broader than the detection zone. When a whole of the specified detection capabil­ity is present in this area, the light of the SL-V is blocked, and then the OSSD goes to OFF state.

Lockout condition

The SL-V performs self-diagnosis for approx. 4.5 seconds after the power is turned on and checks for errors in the SL-V. Self-diagnosis is also performed periodically during normal operations. If the self-diagnosis function detects an error, the SL-V goes to Lockout condition and the OSSD is kept in OFF state even if no interruption exists in the detection zone. The indicators operate in the following man­ner during lockout condition.
Bar LED : Indication corresponding to the cause of the error
See "Troubleshooting" (page A-2)
Function indicator : Interlock indicator is blinking in yellow.
See "Function Indicators" (page 6-5)
Center indicators : All indicators are blinking in red.
See "Center Indicator" (page 6-6) To release the lockout condition, first remove the cause of the error, and then either activate reset input or turn the power off and on again.
See "Time chart for the termination of lockout condition due to reset input" (page 2-13)

OSSD

NOTE
2-2 Self-diagnosis Function
The OSSD is a safety-related control output. It connects to an external device (load), such as an FSD or MPCE. The SL-V generates self-diagnosis signals on its internal control circuit to perform diagnostics on the output circuit (OSSD). These signals periodically force the OSSD into a temporary OFF state when no interruption exists in the detection zone.
The internal control circuit receives a feed-back signal (OFF signal) based on the self-diagnosis, the SL­V determines that its output circuit is operating normally. If this OFF signal is not returned to the internal control circuit, the SL-V determines that there is a problem in its output circuit or wiring and goes to the lockout condition.

2-3 Series Connection

Up to three SL-V units can be serially connected and used as a single light curtain. Use the series con­nection cables that KEYENCE provides as an optional part. ( See "Series connection cable" (page 1-6))
Example of use with 3 units in series connection
Benefits
• Prevents the light interference between the connected SL-Vs
• Simplified wiring because the wiring for OSSD or synchronization cable
• Combining the SL-VF (M), SL-VH (M) and the SL-VL (M) is allowable in series connections even though
they have different respective detection capabilities.
Limitations
• Up to 3 units
• Up to 240 total number of beam axes
• The length of one series connection cable must be 10 m or less. When connecting three units in series,
the total length of two cables must be 20 m or less.
See "Cable Connections" (page 3-11).
Even when series connection cannot be established, light interference is reduced by the light interference prevention function. No special settings are required.
Series connection is required for secure light interference prevention. When not connecting the SL-V units in series, install the units by referring to "Light Interference Prevention Method" (page 3-8)

2-4 Interlock Function

Interlock is a function to prevent that the OSSD automatically goes to the ON-state from the OFF-state. You can prevent the unintended start-up and/or the unintended restart of the machine if the interlock is applied to the SL-V. You can determine whether the interlock function is enabled at start-up, at restart or both through the SL-V Configurator (SL-VH1S). In this sentence, start-up and restart means as follows.
Start-up:
1) When the power is supplied
2) When the SL-V is restored from lockout condition thorough reset input
Functions and Features
Restart:
1) When the OSSD goes back to the ON-state from OFF-state, except for the start-up
On the other hand, you can also determine whether the interlock function is enabled at start-up and at restart through the wiring method.
The setting of combination for start and restart interlock is as follows. (X: available -: not available)

Automatic start mode: Interlock function does not work. The SL-V starts operation automatically without
the reset operation. The OSSD goes to the ON-state automatically if the SL-V detects no interruption in the detection zone at start-up. This mode can be used for the machine that nobody can go into or approach the hazardous area with only passing through the protection zone, or can be used if the safety-related part of a control system other than the SL-V, such as safety relay unit, can ensure the safety with other means.

Manual start mode: Interlock function works. The SL-V starts operation if the SL-V receives the reset
operation. The OSSD keeps the OFF-state at start-up (Interlock condition). It is necessary to perform the reset oper­ation when the SL-V detects no interruption in the detection zone, in order that the machine starts opera­tion. Because of reset operation, the OSSD goes to the ON-state, and then interlock condition is terminated. Unexpected/Unintended start-up of the machine or machinery can be prevented.
Restart mode
Automatic reset mode: Interlock function does not work. The SL-V starts operation automatically without
the reset operation. The OSSD goes to the ON-state automatically at restart if the object detected by the SL-V is removed from the detection zone.

Interlock-reset-ready output
The Interlock-reset-ready output is a NON-SAFETY-RELATED function. The Interlock-reset-ready output (Green wire on the transmitter) is enable when manual start or manual restart is set. This output informs the external devices (non-safety-related devices) that the interlock state on the SL-V is ready to be released by pressing the reset button because the SL-V does not detect any interruptions in the detection zone.
This output is not a safety-related output but just information for usability. Activation of this
output never guarantees the safety of whole machine system and never configures a part of the interlock reset mechanism. The safety of whole machine system must be established by the safety-related control system, and the entire responsibility for that establishment and also the use of this function must be on the customer. Failure to follow this warning may result in significant harm to the machine operators including injury or death.
Refer to page 2-10 for more information on the warning and description about resetting
interlock.
Be sure to confirm absolutely that there is nobody in the hazardous zone, before the inter-
lock is released by the interlock reset mechanism. Failure to follow this warning may result in significant harm to the machine operators including injury or death.
The Interlock-reset-ready output is not allowed to be used as the safety output for safety-
related control system. Usage of this function as safety output may result in significant harm to the machine operators including serious injury or death.

2-7 Wait Input Function

The wait input is a NON-SAFETY-RELATED function. This is the function that puts the OSSD into an OFF state through a signal from an external device (non safety-related device).
How to use
(1) The signal from the external non safety-related control device is connected to the wait input. When
this signal is ON, the OSSD of the SL-V goes to OFF.
This function is useful for testing and making sure that the machine which the SL-V is installed on can stop
(2)
within the specified period of time when the OSSD goes into an OFF state.
The wait output is not allowed to be connected to the safety output provided from the safety­related control system. Connection to the safety output of the safety-related control system may result in significant harm to the machine operators including serious injury or death.
• The SL-V goes into an Interlock condition if the wait input is activated when using manual reset mode.
See "Interlock Function" (page 2-7)
• The OSSD goes into an OFF state when the wait input is activated while the SL-V is muted or in an
override condition. The SL-V returns to normal operation after the wait input is deactivated.
See "Muting function" (page 2-29) See "Override function" (page 2-45)

2-8 State Information Output

The state information output is a NON-SAFETY-RELATED function. The state information output is a function that informs the external devices (non safety-related devices) of the current state of the SL-V. It does this using state information outputs 1 and 2. Two types of output modes are selectable:
(1) Normal mode
The SL-V informs the external devices of the current state of the SL-V through combinations of three outputs: ON/OFF on the AUX output, ON/OFF on the state information output 1, and the number of pulses on state information output 2. Because of this function, a PLC or similar non safety-related devices are able to get detailed information about the current state of the SL-V. When the SL-V Configurator "SL-VH1S" is used, the ON/OFF width of the pulse can be changed.
(2) Simple mode
This mode is simple in that it just informs external, non-safety devices if the SL-V is in a lockout condition or muted. State information output 1 indicates whether or not the SL-V is in a lockout condition while state information output 2 indicates whether or not the SL-V is muted.
Available settings
The settings that can be changed from the SL-V device and the SL-VH1S software are as follows. (O: Setting possible -: Setting not possible)
Item Setting Content Description
Output method
"Pulse speed setting" in normal mode
Normal mode (initial value) Sends a pulse output to indicate the state of the SL-V. O O Simple mode Indicates whether muting or lockout is ON or OFF. O O Standard (initial value) Both the ON and OFF width of each pulse are set to 20 ms. O O Slow
Both the ON and OFF width of each pulse are set to 100 ms.

Summary
When the power turns on, the pulse output (number of pulses on state information output 2 while state information output 1 is ON) indicates that the SL-V is in normal operation. After that, if the SL-V changes to one of the states shown below ("SL­V state" column), the pulse output generates the corresponding number of pulses one time to indicate the state of the SL-V.
• If the SL-V goes into a lockout condition immediately after the power is turned on, the SL-V may not output
the pulses indicating the lockout condition but instead output the pulses indicating the normal operation.
• The SL-V can only output the state information pulses when the communication cable is connected cor-
rectly upon power-up. See "Examples of Wiring" (page 4-5)

NOTE
The alert output is a NON-SAFETY-RELATED function. The amount of light being received decreases as build-up collects on the surface of the SL-V or as machine vibrations cause the beam axes to misalign. If the received light decreases enough, the machine may suddenly stop because the OSSD turns to an OFF state due to beam interruption. The alert output simply informs external, non safety-related devices that the amount of received light is decreasing. The alert output simply informs external, non safety-related devices that the amount of received light has been decreased for more than the alert output monitoring time. The default setting of the alert monitoring time is 5 seconds, but it can be changed through the SL-VH1S.
Functions and Features
Alert output is not allowed to be used as a safety output for safety-related control system. This output should never constitute a part of a safety-related control system. Usage of this function as safety output may result in significant harm to the machine operators, including serious injury or death.

NOTE
The Clear/Blocked output is a NON-SAFETY-RELATED function. This output simply informs the external devices (non safety-related devices) whether the beam axes are clear or blocked. (“Clear” means no interruptions in the detection zone, “Blocked” means there is an interruption in the detection zone.) This output is NOT synchronized with the OSSD operation. For exam­ple, when the SL-V is in an interlock condition, the OSSD will turn OFF while the clear/blocked output indicates “clear”. Another example is if the SL-V is muted or in override mode, the OSSD is ON but the clear/blocked output may indicate “blocked”.
The Clear/Blocked Output is not allowed to be used as a safety output for any safety-related control systems. This output should never constitute a part of a safety-related control system. Using this function as a safety output may result in significant harm to machine operators including serious injury or death.

Temporary Suspension of Safety Function

Muting function

The muting function is used to temporarily suspend the SL-V's safety functions while the SL-V receives a signal from muting devices (such as sensors or switches). Before this function can be used, the outputs from the muting devices must be connected to the muting input terminal on the SL-V. In addition, the SL-VH1S provides the user with the opportunity to select the beam axes to be muted con­dition. You can minimize the number of beam axes to be muted condition through the SL-VH1S. There­fore, you can reduce a risk of approaching into hazardous zone accordingly. You can set the three groups of beam axes that will become muted condition and select these groups through the external input.
For more specific examples of operations or for information about installation when using the muting func­tion, see "System Configuration for the Muting Function" (page 3-22).
Since the muting function temporarily suspends the safety functions of the SL-V, additional
safety measures are required for the whole machine on which the SL-V is installed. This is in order to ensure safety while the muting function is activated.
The muting devices, the installation of those devices and the procedure to activate the mut-
ing function must fulfill the conditions specified in this user’s manual and the requirements of the laws, rules, regulations, and standards in the country or region in which the SL-V and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.
When you install the muting devices (such as sensors or switches), the following conditions
must be fulfilled.
(1) Muting devices must be installed so that the muting function cannot be activated if the
machine that the SL-V is on is in the middle of a hazardous cycle or period.
(2) Muting devices must be installed so that the muting function cannot be activated by
personnel approaching the detection zone of the SL-V.
Only responsible personnel should be allowed to install or wire the muting function or mut-
ing devices.
The muting devices must be installed in such a way that only responsible personnel can
change their installation or orientation by requiring special tools or keys to access the devices.
The whole responsibility for use of the muting function must rest with the customer. Those
who use the muting function must fulfill all of the requirements related to muting functions. KEYENCE accepts NO responsibility or liability for any damage or injury due to unauthor­ized installation, unauthorized usage or maintenance methods that are not specified in this user’s manual and/or due to noncompliance with the laws, rules, regulations and standards set fourth by the country or region in which the SL-V is used.
The installation of muting lamp may be required by the laws, rules, regulations, and stan-
dards in the country or region in which the SL-V is used if you apply the muting function. It depends on the machine application and/or the result of your risk assessment. If it is neces­sary for you to provide the muting lamp, you must fulfill the requirements because you are fully responsible for installation of muting lamp.
The users who intend to use the option related to the conditions for muting (page 2-33)
must perform the risk assessment based on their machine application.

Limitations
Muting device
• The muting device output must be N.O. (normal open).
• A PNP output muting device is required when using the PNP output type cable and an NPN output muting device is required when using the NPN output type cable. The muting device must be capa­ble of 2 to 3 mA current.
• Do not use one muting device with multiple outputs in place of two or more muting devices. (Only one output per one muting device must be used.)
• If the muting device has a timer function that can adjust the output timing, do not use that function.
Muting lamp
When using the muting lamp, it must meet the following conditions.
For an incandescent lamp : rated 24 V DC, 1 to 7 W For LED indicator : rated current consumption must be 10 to 300 mA.
If the incandescent lamp burns out, or if the lamp used does not meet the above conditions, the state

(time period between muting input 1 and 2)
(1) Follow the procedure under "Entering the password". "Entering the password" (page 2-39) (2) This setting depends on the state of the override input (red/black wire on the receiver).
ON: The condition for initiation of muting (time period of 0.04s to 3s between muting input 1 and 2) is deac-
tivated, which means that the time period of 0.04s to no defined time is active. (the interlock indicator on the
receiver blinks.)
OFF: The condition for initiation of muting (time period of 0.04s to 3s between muting input 1 and 2) is acti-
vated, which means the default time period is active. (The interlock indicator on the receiver does not light.) (3) Turn ON the muting input 1.
Turn ON the muting input 2, and then turn OFF the muting input 2. The bar LED 1 on the receiver lights in green.

wards, the center indicator on the receiver lights in red and then lights in green again approximately
one second later. This indicates that the settings are completed. (10) Turn OFF the power to the SL-V, and then the interlock mode selection input (pink wire from the
transmitter) must be wired.
"Interlock Function" (page 2-7)
The condition for initiation of muting (time period between muting input 1 and 2) is changed when the
(11)
power to the SL-V is turned ON. The SL-V keeps this condition even if the power to the SL-V is turned OFF.
When muting input 2 turns ON more than 3 seconds after muting input 1 turns ON in case where both the condition for termination of muting (maximum muting period of approx. 5 minutes) and the condition for initiation of muting (time period of 0.04s to 3s between muting input 1 and 2) are deactivated, muted con­dition is terminated approx. 5 minutes later even if the condition for termination of muting (maximum mut­ing period of approx. 5 minutes) is deactivated. This is for the avoidance of unintended and/or infinite muted condition.

The OSSD goes to an OFF state if the muting function is deactivated and an interruption remains in the detection zone of the SL-V. The OSSD OFF state will remain until the obstruction is removed.
The override function allows a temporary manual suspension of the SL-V safety functions. This makes it possible to remove the obstruction remaining in the detection zone of the SL-V. (Machine is able to be manually operated on a temporary basis because the safety function of the SL-V is temporarily suspended.)

The override function allows a temporary manual suspension of the SL-V safety func-
tions.Thus, in order to ensure safety while the override function is activated, additional safety measures are required for the whole machine system on which the SL-V is installed.
The devices, the installation of those devices, and the procedures to activate the override
function must fulfill the conditions specified in this user’s manual as well as the require­ments of the laws, rules, regulations, and standards in the country or region in which the SL-V and those devices are used. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.
The override function allows a temporary manual suspension of the SL-V safety functions.
Manual operation devices are required to activate the override function. When installing the devices to activate the override function, the devices must be installed so that the whole hazardous zone can be checked by responsible personnel and that the device operators are not in the hazardous zone.
Be sure to confirm that there is nobody in the hazardous zone, before the override is acti-
vated. Failure to follow this warning may result in significant harm to the machine operators, including serious injury or death.
The installation of the indication for override may be required by the laws, rules, regulations,
and standards in the country or region in which the SL-V is used if you apply the override function. It depends on the machine application and/or the result of your risk assessment. If it is necessary for you to provide the indication for override, you must fulfill the requirements because you are fully responsible for installation of the indication for override. Only the responsible personnel must be allowed use or activation of the override function.

2-12 Fixed Blanking

Danger
: Danger zone
Obstacle
Functions and Features
This function is only enabled through the SL-VH1S. In case of normal operation, the OSSD keeps the ON state while the SL-V detects no interruption in the detection zone, and the OSSD goes to the OFF state when the SL-V detects interruption in the detec­tion zone. On the other hand, if the fixed blanking is enabled to a certain beam axis, the OSSD keeps the ON state while the SL-V detects interruption on that beam axis and no interruption in the detection zone except for that beam axis. Additionally, the OSSD goes to the OFF state when the SL-V detects no interruption on that beam axis and interruption in the detection zone except for that beam axis.
As shown in the right figure, when the fixed blanking function is applied, a hazardous clearance that is not protected by the SL-V may be generated between the obstacle and the SL-V. You must install an additional safety measure such as a safeguard for this clearance.

2-13 Reduced Resolution

Danger
Reference
This function is only enabled through the SL-VH1S. In case of normal operation, the OSSD goes to the OFF state when the SL-V detects interruption in the detection zone. When you enable this function and set the number of ignored beams, the OSSD keeps the ON state when the number of beams blocked by the object is less than or equal to the set number of ignored beams. The OSSD only changes to the OFF state when the object consecutively interrupts more beams than the set number of ignored beams. The reduced resolution can be enabled to any of beam axis, including the beam axis of SL-V in series connection.
When the reduced resolution function is applied, the detection capability varies depending on your configuration. The following is the calculating formula. [Detection capability under the reduced resolution function]=[Original detection capability]+[Beam axis spacing]*[Number of ignored beams] Therefore, make sure to accurately calculate the safety distance according to the detection capability, and install the SL-V at a distance greater than or equal to the minimum safety distance away from the hazardous zone or hazard. The installation of additional safety measures, such as a safeguarding, may be required if the detection capability varies due to the configuration of the reduced resolution function. On your own responsibility, you must perform the risk assessment based on your configuration of the reduced resolution function in order to reduce the risk.
Example: The number of ignored beams is set to "1"
The OSSD goes to OFF-state when the consecutive two beam axes are interrupted.

2-14 I/O Monitoring Function

The I/O monitoring function is a NON-SAFETY-RELATED function. This function simply informs the user of the state of several I/Os on the SL-V through the indicators of the SL-V. Connection with a PLC or other input device can be verified, as the non safety-related outputs (i.e. except for OSSD) can be activated through the I/O monitoring function. The OSSD keeps an OFF state while the I/O monitoring function is activated.
How to use the I/O monitoring function
1. Turn OFF the power to the SL-V.
2. With the interlock mode selection input (pink wire on the transmitter) open (completely disconnected),
turn ON the power. The SL-V will activate the I/O monitoring function. When the I/O monitoring function is activated, all the center indicators turn OFF. Bar LED No. 1 on the transmitter lights red. On the receiver, bar LED No. 1 lights red when using the NPN output type cable, and bar LED No. 2 lights red when using the PNP output type cable.
3. To deactivate the I/O monitoring function, turn OFF the power, then connect the interlock mode selec-
tion input to a +24 V or 0 V source. Turn ON the power to complete the deactivation.
See "Interlock Function" (page 2-7)
• The I/O monitoring function cannot be used if the interlock is configured through the SL-V1HS. (The I/O monitoring function is not activated even if the interlock selection input is kept open circuit.)
• The interlock mode selection input must be open (completely disconnected) while the I/O monitoring function is activated. If this input is connected to +24 V or 0 V, the bar LED indicators and the function indicators will show irregular operation.

Danger

Mounting position

Correct position
• The machine operators are able to approach the hazardous zone or hazards only passing through the detection zone of the SL-V.
• While the machine is running, the machine operator must always stay on the opposite side of the haz­ardous zone or hazard.
Safe Safe
Additional protective measures
Installation to a Machine
Incorrect position
• The machine operator can access the hazardous zone or hazards without passing through the detec­tion zone of the SL-V.
• While the machine is running, the machine operator or a part of machine operator‘s body can stay at the position between the detection zone of the SL-V and hazardous zone or hazard.
Dangerous
Additional protective measures, such as a mechanical safety guard, must be installed to protect areas not covered by the SL-V. NEVER install the SL-V in a manner which allows an operator to position his body or part of his body between the SL-V and the hazardous zone, without first passing through the plane of the SL-V. Failure to do so can result in serious bodily injury or death.

3-2 Safety Distances

The safety distance is the minimum allowable mounting distance between the SL-V and the hazard point, which allows complete stoppage of hazardous motion before an individual reaches the hazard point. The starting point (origin) for the safety distance must be the center line of the SL-V‘s surface. (See below figure.) The following safety distance calculations are for cases where the detection zone is orthogonal to the direction of approach. For all other cases, you must refer to the laws, rules, regulations or standards in the country in which the SL-V is installed.
Center line
Installation reference mark
The installation of the SL-V must ensure the required safety distance in compliance with the requirements of laws, rules, regulations and standards in the country or region in which the SL-V is installed. Mounting the SL-V closer to the hazard point than the calculated safety distance can result in serious bodily injury or death.

Example 1: ISO13855 (EN ISO13855)
Safety distance calculation according to ISO13855:2010 (EN ISO13855:2010) (in a case where the detection zone is orthogonal to the direction of approach)
Formula S= K x T + C..... (A)
S : Safety distance (mm)
K : Approaching speed of the body or the parts of body into detection zone (mm/s)
T : Overall system stopping performance (s) (T= t1 + t2) t1 : SL-V maximum response time See "Response time (OSSD)" (page 7-7) t2 : Maximum time required by the machine to stop after receiving the signal from protective
equipment (s) (SL-V)
C : Additional distance (mm) calculated from the SL-V detection capability.
Calculation example for a detection capability of 40 mm (1.57") or less
The safety distance is calculated using Formula (A) and the parameters established in ISO13855 (EN ISO13855) with K = 2,000 mm/s and C = 8 (d - 14 mm (0.55")). C is a value determined from the d :SL­V detection capability diameter (mm) and must be equal or greater than 0. This section provides an example of the calculation when using the SL-V08H (8 beam axes).
S= 2,000 mm/s x (t1 + t2) + 8 (d - 14 mm (0.55"))..... (B)
When t1 = 7 ms, t2 = 50 ms, d = 25 mm (0.98"): S= 2,000 mm/s x (0.007 s + 0.05 s) + 8 (25 mm (0.98") - 14 mm (0.55")) = 202 mm (8.58")
Installation to a Machine
The safety distance calculated using Formula (B) above must be 100 mm (3.94") or more. (From ISO13855 Clause 6.2.3 and EN ISO13855 Clause 6.2.3)
If on the other hand the safety distance calculated using Formula (B) above exceeds 500 mm (19.69"), set K = 1,600 mm/s and calculate the safety distance again using Formula (A). When the calculated safety distance is less than 500 mm (19.69"), use a safety distance of S = 500 mm (19.69"). (From ISO13855 Clause 6.2.3 and EN ISO13855 Clause 6.2.3)
Calculation example for a detection capability of 40 mm (1.57") or more and 70 mm
(2.76") or less
This section provides an example of the calculation when using the SL-V30L (30 beam axes). The safety distance is calculated using Formula (A) and the parameters established in ISO13855 (EN ISO13855) with K = 1,600 mm/s and C = 850 mm (33.46").
S= 1,600 mm/s x (t1 + t2) + 850 mm (33.46")
When t1 = 10 ms, t2 = 50 ms, S= 1,600 mm/s x (0.01 s + 0.05 s) + 850 mm (33.46") = 946 mm (37.17") Accordingly, the safety distance for this application is S = 946 mm (37.17").

One of the accepted values for K is the hand speed constant (It is usually considered as the horizontal motion of the hand and arm while seated). Its common value is 1.6m/s (63inch/s) although other values (typically greater) are also used. The hand speed constant does not include other body movements, which can affect the actual approach speed. Consideration of the above factors should be included when determining the speed constant for a given application. OSHA 1910.217(c) provides K = 63 inch/s (= 1,600 mm/s) as a recommended value.

3-3 Light Interference Prevention Method

Light Interference Prevention Function

The light interference prevention function automatically reduces mutual interference between SL-V units. Additionally, mutual interference can be reduced by changing the emitting frequency through the SL-VH1S configuration software. The emitting frequency can be set to TYPE-A or TYPE-B. To use with the combination of SL-V set TYPE-A and TYPE-B, can reduce the chance of mutual interference more than the combination of same type of emitting frequency. Refer to the "SL-VH1S User’s Manual" for information about changing the laser frequency.

Series Connection

Connecting SL-V in series can prevent mutual interference.

When using the unit connection cable, junction cable, and extension cable together, the sum of the length for all type of cables must be 30 m or less. This limitation is applicable to each the transmitter and receiver respectively. Since up to 3 SL-V units can be connected in series, up to 2 sets of series connection cables are required. Two sets of the SL-VS10 (cable length :10 m) cables can be used. In this case, the sum of the length of all type of cables, including the series connection cable, must be 50 m or less. This limitation is also applicable to each transmitter and receiver respectively.
Cables must be within the lengths specified. Failure to follow this specification may cause
improper operation of safety function, and may cause dangerous situation.
The series connection cable cannot be cut or extended. If the cable is cut or extended,
safety features may not operate properly. Do not allow this to happen as it is extremely dan­gerous.
Installation to a Machine
(2) Minimum cable bending radius : 5 mm
(3) Identification of connector cables
Cables can be identified by the colors of their connectors and their cable insulation.
1. Cable Insulation colors Cables connected to the transmitter : Color of cable insulation in grey Cables connected to the receiver : Color of cable insulation in black
2. Connector colors PNP output type cables or series connection cables : Black connectors NPN output type cables : Grey connectors
PNP output type cables and NPN output type cables cannot be used at the same time (mixed wiring is not possible). One type of cable must be chosen based on the application. Be sure to connect the unit connection cable for receiver to the SL-V receiver and the unit connection cable for transmitter to the SL-V transmitter.

System Configuration for the Muting Function

Muting is the function that temporarily deactivates the SL-V safety function while the SL-V receives the signal from the muting devices (such as sensors or switches). Output from muting devices must be connected to the muting input terminal on the SL-V in order to use this function.
Conditions that activate the muted condition
The muted condition is activated if all of the following conditions are met.
• In case where muting input 2 turns ON within 0.04 to 3 seconds after muting input 1 turns ON.
• In case where the SL-V detects no interruption in the detection area.
• In case where OSSD is ON state and keeps staying for 0.5 seconds or more.
Conditions that deactivate the muted condition
The muted condition is deactivated if any of the following five conditions is met.
• In case where either the muting input 1 or the muting input 2 turn OFF for at least 0.02 s
• In case where the SL-V goes into a lockout condition.
• In case where wait input turns ON.
• In case where the power is not supplied or is turned on again.
• In case where 5 minutes for muting limitation has passed.
See "Muting function" (page 2-29) for details and an explanation of the muting function, as well as cautions and warnings.

Example: Muting function with 2 muting devices (Sensors)

The following is an example of the muted condition while the workpiece is passing through the detection area of the SL-V. In this example, 2 retro-reflective photoelectric sensors are used as the muting devices (ON when the beam from the sensor is blocked). You can refer to this example if a workpiece cannot be distinguished from a person because of the size of the workpiece.
Conditions for installation of muting device
All 4 of the following conditions must be met in order to ensure the continuous muted condition while the workpiece is passing through the detection area.
L (mm) : The length of workpiece D (mm) : Displacement distance between the point where the workpiece interrupts the beam. V (mm/s) : Workpiece speed The activation time of muting input 1 and that of muting input 2 must be between (1) 0.04 < D / V < 3 (2) D < L (3)
Both sensors A1 and sensor A2 must be installed where their beams intersect in the hazardous area.
(4) Both sensors A1 and sensor A2 must turn ON when the beam is blocked (Dark ON).

(1) The workpiece is approaching to
the detection zone, however, the SL-V does not go to the muted condition because both muting input 1 and 2 are OFF. At this point, the SL-V continues normal opera­tions, and OSSD goes OFF if the SL-V gets interrupted.
(2) The workpiece interrupts the beam
from sensor A1 first, and then inter­rupts the beam from sensor A2. Then the SL-V goes into the muted condition and the OSSD does not turn off even if the SL-V detects an interruption.
