•No person other than the responsible personnel and machine operators should be allowed to install or test the SL-V.

•When performing electrical wiring, always fulfill the electrical standards and regulations for the country or region in which the SL-V is used.

Environment of use

Danger	• Do not use the SL-V in an environment (temperature, humidity, interfering light, etc.) that
	does not conform to the specifications contained in this user’s manual.

•Be sure to confirm that the SL-V keeps normal operation when electromagnetic radiation is generated by wireless devices. (If you use wireless devices such as cellular phones or transceivers in the vicinity of the SL-V.)

•The SL-V is not designed to be explosion-proof. Never use it in the presence of flammable or explosive gases or elements.

•Be sure to confirm no deterioration in product quality if you use the SL-V in the presence of substances, such as heavy smoke, particulate matter, or corrosive chemical agents.

•Do not install the SL-V in areas where the SL-V is exposed to intense interference light such as direct sunlight, and direct or indirect light from inverter-type fluorescent lamp (rapid-start type lamp, high-frequency operation type lamp, etc).

•Be sure to absolutely confirm that there is nobody in the hazardous zone, before the interlock is released (i.e. the machine system restarts) by the interlock reset mechanism. Failure to follow this warning results in a significant harm to the machine operators, including serious injury or death.

•Be sure to absolutely confirm that there is nobody in the hazardous zone, before the override function is activated. Failure to follow this warning results in a significant harm to the machine operators, including serious injury or death.

Target machine

Danger

•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.

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.

•The installation of muting lamp 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 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 SL- V in accordance with the torque values specified in this user’s manual.

Circuit design and wiring

Danger • 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.

4	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%.

(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 interlock- reset-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.

Cables
NOTE	• There are two types of cable: simple function type and multi-function type. The type of cable used deter-
	mines the function that can be used. (The number of conductors is different from each other.) There-
	fore, 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).

Danger If a series connection cable has been cut or extended, it is not allowed to be used for the SL-V. Use of a cut or extended cable may cause the safety function not to operate properly and may cause a dangerous situation.

Cable length specification

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.

Danger 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.

•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.

When the SL-V Configurator is used, the following setting changes and functions are available.

	Items		Description	Refer to page
	Muting function	You can select the beam axes to be muted. The muting conditions can also be changed.		2-29

	Override function	You can change the override condition.		2-45
		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
	Interlock function	zone. Automatic or manual can be selected individually for start and restart.		2-7
		Automatic start mode	: The OSSD automatically enters the ON-state when
			no interruptions are present in the detection zone.
		Manual start mode	: Enters interlock condition upon startup.
		Automatic reset mode : The OSSD automatically returns to the ON-state when
			no interruptions are present in the detection zone.
		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
	Fixed blanking function	receiver as well as on the all beam axes including the SL-V connected in		2-48
		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.

1-3 Part Description

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.

			b
		a
	Detection		Protection height

			c
	a: Beam axis spacing
	b: Beam axis diameter		Specified detection capability (position B)
	c: Detection capability

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 capabil-
	ity is present in this area, the light of the SL-V is blocked, and then the OSSD goes to
	OFF state.

2-2 Self-diagnosis Function

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 man-

ner 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)

2-2 Self-diagnosis Function

OSSD

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 SL- V 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).

	Reference		Even when series connection cannot be established, light interference is reduced by the light
			interference prevention function. No special settings are required.

NOTE	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)
