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. 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 t he indication for override.

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.
