Safety Precautions

General precautions

• You must verify that the SL-VHS is operating correctly in terms of functionality and performance before the start of machine and the operation of the SL-VHS.

• KEYENCE does not guarantee the function or performance of the SL-VHS if it is used in a manner that differs from the SL-VHS specifications contained in this instruction manual or if the SL-VHS is modified by the customer.

• When using the SL-VHS to protect machine operators against a hazard or hazardous zone or using the SL-VHS as a safety component for any purpose, always follow the applicable requirements of the laws, rules, regulations and standards in the country or region where the SL-VHS is used. For such regulations, you should contact directly to the regulatory agency responsible for occupational safety and health in your country or region.

• Depending on the type of machine on which the SL-VHS is to be installed, there may be special safety regulations related to the use, installation, maintenance, and operation of the safety component. In such a case, you must fulfill such safety regulations. The responsible personnel must install the SL-VHS in strict compliance with such safety regulations.

• The responsible personnel must do the training to the assigned personnel for the correct use, installation, maintenance, and operation of the SL-VHS. "Machine operators" refers to personnel who have received appropriate training from the responsible personnel and are qualified to operate the machine correctly.

• Machine operators must have specialized training for the SL-VHS, and they must understand and fulfill the safety regulations in the country or region in which they are using the SL-VHS.

• When the SL-VHS fails to operate, machine operators must immediately stop the use of the machine and the SL-VHS and report this fact to the responsible personnel.

• The SL-VHS is designed with the assumption that it would be correctly installed in accordance with the installation procedures described in this instruction manual and correctly operated according to the instructions in this instruction manual. You must perform an appropriate installation of the SL-VHS after performing a sufficient risk assessment for the target machine.

• The SL-VHS should be processed as an industrial waste product when being disposed.

Precaution on use

■ Operators

• In order to operate the SL-VHS correctly, the responsible personnel and/or machine operators must fulfill all of the procedures described in this instruction manual.

• No person other than the responsible personnel should be allowed to install or test the SL-VHS.

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

Danger

• The SL-VHS must be installed only after ensuring the minimum safety distance between the SL-VHS and the hazardous zone or hazard as established by the applicable regulations in the country or region in which the SL-VHS is used. (e.g. EN999 (ISO 13855) in EU countries)

• Choose locations for the installation of the SL-VHS 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-VHS. Correct operation and detection is not possible if the receiver has a different beam axis spacing

• (detection capab ility) from that of the transmi tter. You must verify that the beam axis spacing (detection capability) is the same between the transmitter and the receiver when installing the SL-VHS.

•

The SL-VHS must be installed so that the machine operator is able to go into or approach the hazardous zone or hazards only by passing thro ugh the detection zone of the SL-VHS. Strictly avoid installa tion that allows the machine operator or a par t of the machine operator's body to go int o or approach the hazardous zone or hazards without passi ng through the detection zone of the SL-VHS or to remai n in a position between the detection zone of the SL-VHS and the haz ardous zone or hazard. In case where you install the SL-VHS units in series (ser ies connection), you always must check the installation ca refully whether you follow this warning, especially after in stallation and maintenance.

• You must always perform the pre-check tests after installing the SL-VHS in accordance with the pre-check test procedures, such as items specified in this instruction manual, in order to verify that the test pieces can be detected in all of the detection zones.

• Muting is a function to allow a temporary automatic suspension of the SL-VHS safety functions while the SL-VHS is receiving a signal from one or more muting devices (such as sensors or switches). Therefore, additional safety measures are required for the machine on which the SL-VHS 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 instruction manual and the requirements of the laws, rules, regulations and standards in the country or region in which the SL-VHS 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-VHS.

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-VHS 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 override is a function to allow a te mporary manual suspension of t he safety functions of

• the SL-VHS. Therefore, additional safety measures are required for the whole machine system on which the SL-VHS is instal led 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-VHS 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, thos e devices must be installed so that the whole hazardous zone can be checked by the respons ible personnel and so that it is not possible for machine operators to operate those devices in the hazardo us zone.

•

The installation of the indicati on for override may be required by the laws, rules, regulations, and standards in the country or region in which the SL -VHS is used if you apply the override function. It depends o n the machine application and/or the result of your risk asses sment.

The customer is fully responsible for complying with the requ irements 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 inst allation, usage or maintenance, which are not specified in this instruction manual, and/or due to noncompliance with the laws, rules, regulations and standards in the country or regi on in which the SL-VHS is used.

• Securely tighten mounting brackets and cable connectors used for the installation of the SL-VHS in accordance with the torque values specified in this instruction manual.

■ Circuit design and wiring

• Always turn off the power to the SL-VHS when performing electrical wiring.

• You must fulfill the electrical standards and regulations in the country or region in which the SL-VHS is being used when you perform the electrical wiring.

• To avoid the risk of electric shock, do not connect any of the SL-VHS inputs to DC power sources outside of the range of 24 VDC + 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-VHS with reinforced insulation or double insulation.

• In order to fulfill the requirements in IEC61496-1, UL61496-1, EN61496-1 and UL508, power supply for the SL-VHS must fulfill the conditions listed below.

A rated output voltage of 24 VDC (SELV, Overvoltage Category II) within +10 % and -20 %.

(a) (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-VHS 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-VHS is used in the United States or Canada.

• Do not install the electric wiring of the SL-VHS together with or in parallel with high-voltage electrical or power lines.

•

Both OSSD outputs provided on the SL-VHS must be used to establish a safety-related machine control system. Establishing a safety-related machin e 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 operat ors, including serious injury or death.

•

When using a PNP output type cable, do not cause short-circuit between the OSSD and +24 V. Otherwise, the OSSDs keep staying at the ON-state and it causes a dangero us situation.

•

When using a PNP output type cable, be sure to connect the load between the OSSD and 0 V to avoid a dangerous situation. If the load is incorrectly connected between the OSSD and +24 V, the logic of the OSSD operation will be reversed and the OSSD will change to an ON state when the SL-VHS 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 0 V. 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 +24 V 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-VHS detects the interruption in the detection zone. This is a dangerous situation.

•

In case of wiring, regardless of P NP 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 ear th fault.

• The Alert output, AUX output, Clear/Blocked Output, and state information 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 co mprising a part of

• the safety-related machine control system. If the wait input is connect ed to the output of a safety component it may result in a significant harm to the mach ine operators, including serious injury or death.

• The transmitter and receiver cables must be within the lengths specified in this instruction 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-VHS and before the machine startup.

• If the SL-VHS does not operate properly when you perform pre-check test in accordance with the pre-check test procedures specified in this instruction 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-VHS.

• The responsible personnel must perform maintenance procedures as specified in this instruction manual at least once every six months to ensure safety to the machine and SL-VHS.

Description

OSSD state ON ON ON ON

For the definition of the amount of receiving light of 100 %, 100 % means a threshold between OSSDON and OSSD-OFF. In case of around 100 %, the light curtain easily goes to ON state or OFF state due to environmental or installation factor, such as dust, pollution, angle, vibration or the like.

● During lockout condition

If the SL-VHS has detected any kind of irregularity, the OSSD (control output) will lock itself in the OFF state. When this occurs, bar LEDs 1 through 5 will indicate the source of the problem and the center display light will blink red. To end the lockout condition, solve the source problem and send reset output or turn the device off and then back on again. Try the following measures.

Interlock Function

With the SL-VHS, OSSD automatically turns ON upon startup (when the power turns on or the lockout error condition is terminated by reset input) or restart (when the SL-VHS is blocked and OSSD turns OFF) if no interruption is present in the detection zone. Therefore, safety must be secured by combining a device that connects OSSD (such as safety relay unit), or a machine that prevents entrance to the hazardous zone merely by passing through the protection zone or detection zone of the SL-VHS.

Temporary Suspension of Safety Function

■ Muting Function

The muting function is used to temporarily suspend the SL-VHS's safety functions while the SL-VHS receives a signal from one or more 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-VHS.

● Muting device

When using the muting device, it must meet the following conditions.

• The muting device output must be N.O. (normal open).

• Output of the muting device must be the output with contacts, and must be PNP output type if PNP output type cable is used, or NPN output type if NPN output type cable is used. Also, 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 can be used per muting device.)

• 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 VDC, 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 information output shows a muting lamp error.

● Conditions for initiation of muting

Muted condition is initiated if all of the following conditions are met.

• Muting input 2 turns ON within 0.04 to 3 seconds after muting input 1 turns ON

• SL-VHS detects no interruption in the detection zone

• OSSD is ON state.

● Conditions for termination of muting

Muted condition is terminated if one of the following conditions is met.

• Either of muting inputs goes to OFF state at least for more than 0.02 sec.

• Light curtain goes to lockout condition

• Wait input goes to ON state

• The power supply is interrupted or restored.

• Maximum muting period of approx. 5 minutes has been passed.

■ Override function

The OSSD goes to an OFF state if the muting function is deactivated and an interruption remains in the detection zone of the SL-VHS. The OSSD OFF state will remain until the obstruction is removed.

The override is a function to allow a temporary manual suspension of the SL-VHS safety functions. This makes it possible to remove the obstruction remaining in the detection zone of the SL-VHS. (Machine is able to be manually operated on a temporary basis because the safety function of the SL-VHS is temporarily suspended.)

● Conditions for initiation of override

Override function is initiated if all of the following conditions are met and the reset input goes to ON state within 0.04 to 1 seconds after override input turns ON state.

• SL-VHS is not in the lockout condition.

• SL-VHS detects interruption in the detection zone. (One or more beam axis is blocked.)

• OSSD is OFF state. (including interlock condition)

• Either of muting inputs, or both, turns ON state

● Conditions for termination of override

Override function is terminated if one of the following conditions is met.

• All of muting inputs turn OFF state.

• Either override input or reset input, or both, turns OFF state.

• Light curtain goes to lockout condition

• Wait input turns ON state.

• Maximum override period of approx. 60 seconds has been passed.

Dimensions and Specifications

If the length for a single SL-VHS unit is 710 mm or greater, use a compact E-to-E mounting bracket or an E-to-E mounting bracket additionally as an intermediate support bracket. The following figures show the example for the use of one compact E-to-E bracket or space-saving bracket.

*1 If the interruption is present in the detection zone for less than 80 ms, the response time (OFF to ON) is to be 80 ms or

more to ensure that the OSSD keeps OFF state for more than 80 ms.

When connecting the SL-VHS units in series, the response time (ON to OFF) is the sum of the response times of all the individual SL-VHS units.

When connecting the SL-V32HS (32 beam axes), SL-V24HS (24 beam axes), and SL-V12HS (12 beam axes) in series, the response time of each unit is 10.3 ms, 9.2 ms, and 7.6 ms respectively, and the response time (ON to OFF) is 10.3 ms + 9.2 ms + 7.6 ms = 27.1 ms. the response time (OFF to ON) is 27.1 ms + 40 ms = 67.1 ms.

Checklist

Start

Stop

You are fully responsible for performing the risk assessment on your machine application, taking into account performing maintenance and inspections, which are critical factor for appropriate risk assessment. In addition, it is a responsibility for the responsible personnel to train the machine operators regarding inspection and maintenance of the machine and the SL-VHS.

■ Inspection before operation (Initial inspection)

When the installation of the SL-VHS is completed, the responsible personnel must verify the operation of the SL-VHS in accordance with the checklist shown below. Note that the following inspection items comprise only a bare minimum inspection. KEYENCE Corporation strongly recommends including the necessary checking items into this checklist based on the judgment of the responsible personnel since additional criteria may be necessary depending on both the machine to which the SL-VHS is installed and the laws, rules, regulations and standards in the country or region in which the SL-VHS is used/ installed.

(1) Pre-check for installation condition

❑

The machine on which the SL-VHS is installed can be caused to stop running by the OFF-state of OSSD.

❑ The SL-VHS is installed so that the machine operator cannot go into or approach the hazardous

zone or hazard without passing through the detection zone.

❑ The device to activate the override is installed so that it cannot be operated if there are any per-

sonnel within the hazardous zone.

❑

The SL-VHS has been installed at a distance greater than or equal to the minimum safety distance required .

❑ If there are glossy surfaces nearby, move them so that they are beyond the minimum installation

distance.

❑ The SL-VHS is installed at a location free from light interference, for example fluorescent lamps. ❑ The transmitters and receivers are paired correctly. ❑ The beam axis spacing (detection capability) is the same between the transmitter and the

receiver when installing the SL-VHS.

❑

The muting devices fulfill the conditions specified in this instruction manual and the requirements of the laws, rules, regulations and standards in the country or region in which the SL-VHS and those devices are used.

❑ The devices used to activate the override fulfill the conditions specified in this manual and

requirements of the laws, rules, regulations and standards in the country or region in which the SL-VHS and those devices are used.

❑ Risk assessment was performed on your own responsibility based on your machine application,

and then the installation of SL-V was also based on its result.

(2) Pre-check for wiring

❑ The SL-VHS power supply is 24 VDC, fulfill the conditions for the power supply as specified in this

instruction manual.

❑ The transmitter and receiver cables are installed correctly. ❑

The two of OSSD outputs provided in the SL-VHS are both used as a safety-related machine control system.

❑ The polarity is not reversed with the connection to the power supply. ❑ In case of using PNP output type cable, the OSSD is not short-circuited to +24 V, and the load is

between the OSSD and 0 V.

❑ In case of using NPN output type cable, the OSSD is not short-circuited to 0 V, and the load is

between the OSSD and +24 V.

❑ When two or more SL-VHS are connected in series, they are connected using the dedicated

series connection cable, which is not cut or extended.

❑ Alert output, AUX output, Clear/Blocked Output, and state information output are not used as

safety output for safety systems.

❑ The cable sheaths are not damaged. The protection against the disconnection or short-circuit of

cable, which might be caused by crushing or being caught in a machine, is taken into account.

❑

If two or more sets of the SL-VHS units are used in the vicinity of each other, the protection measures against light interference is done through a series connection method or light interference prevention method.

❑ All of NON-SAFETY-RELATED functions described in this instruction manual are not a part of /

whole of safety-related machine control system.

(3) Pre-check test while the machine is stopped.

You should do the following pre-check test with the test piece in order to make sure the operation of the SL-VHS while the machine is stopped.

❑

The OSSD indicator on the SL-VHS lights in red and the OSSD turns OFF while the test piece is present in the detection zone. The following figure shows the movement procedure of the test piece.

■ Inspection prior to daily operation (Daily inspection)

You should check the SL-VHS operation and the machine operation according to the following checklist prior to daily operation. Note that the following inspection items comprise only a bare minimum inspection. KEYENCE Corporation strongly recommends including the necessary checking items into this checklist based on the judgment of the responsible personnel since additional criteria may be necessary depending on both the machine to which the SL-VHS is installed and the laws, rules, regulations and standards in the country or region in which the SL-VHS is used/installed. Also, the responsible personnel has a responsibility to instruct the machine operators about the inspection and maintenance of the machine and the SL-VHS. The result of this inspection must be kept on record along with the machine log.

(1) Pre-check for installation condition

❑ The SL-VHS is installed so that the machine operator cannot go into or approach the hazardous

zone or hazard without passing through the detection zone.

❑

The SL-VHS has been installed at a distance greater than or equal to the minimum safety distance required.

❑ The SL-VHS is installed at a location free from light interference, for example fluorescent lamps. ❑ The cable sheaths are not damaged. The protection against the disconnection or short-circuit of

cable, which might be caused by crushing or being caught in a machine, is taken into account. Additionally, you should perform the following inspections as described in "Inspection before operation". (3) Pre-check test while the machine is stopped (4) Pre-check test while the machine is operating

❑ There is no change of installation that would influence the result of your original risk assessment.

■ Regular (periodical) inspection

The responsible personnel must perform a regular inspection at least once every six months. Note that the following inspection items comprise only a bare minimum inspection. KEYENCE Corporation strongly recommends including the necessary checking items into this checklist based on the judgment of the responsible personnel since additional criteria may be necessary depending on both the machine to which the SL-VHS is installed and the laws, rules, regulations and standards in the country or region in which the SL-VHS is used/installed. The result of this inspection must be kept on record along with the machine log.

(1) Additional inspection items

❑ The actual distance between the hazardous zone or hazards and the SL-VHS still keeps greater

than the calculated safety distance.

❑ The stop time of the machine connected to the SL-VHS has not increased. ❑ There are no loose screws in the mounting bracket. ❑ The unit connection cable or the series connection cable is fastened tightly to the SL-VHS with no

loose screws.

❑ The OSSD is connected correctly to the machine. ❑ There is no damage to the SL-VHS that may influence IP65 structure. ❑ The surface of the SL-VHS is not polluted or damaged. ❑ Beam axes must be aligned. If it is out of alignment, adjust the beam axes to be aligned. ❑ There is no change of installation that would influence the result of your original risk assessment.

❑

The OSSD indicator and all bar LEDS light in green if no test piece is present in the detection zone.

❑

When the EDM function is applied, the SL-VHS goes to a lockout condition and the OSSD indicator on the SL-VHS lights in red if the EDM input opens while the test piece is present in the detection zone.

(4) Pre-check test while the machine is operating.

The purpose of this pre-check test is to make sure that the machine (hazards) stops its operation. This test must be done after you completely make sure that there is nobody in the hazardous zone.

❑ The machine stops if the test piece is present in the detection zone. It is recommended to try

three locations of test piece: near the transmitter, near the receiver, and in the central area of the detection zone.

❑ The machine (hazard) still stops its operation as long as the test piece is present in the specified

detection zone. This test should be done for the whole detection zone.

❑ The machine (hazard) stops its operation when the power for the SL-VHS is disconnected. ❑ Minimum safety distance is ensured, which has been calculated according to the laws, regula-

tions, and standards of the country and region in which the SL-VHS is installed.
