2. General Precautions
•Verify that this device is operating normally in terms of functionality and performance before the start of
work and before the start of device operation.
• KEYENCE is unable to warrant the function or performance of the SL-C if it is used in a manner that
differs from the SL-C specifications contained in this instruction manual or if the SL-C is modified.
• When using the SL-C to protect machine operators from a hazardous zone or a hazard, or using it as
safety equipment for any purpose, always follow the applicable requirements, regulations, and laws
(collectively “regulations”) existing in the country or region where the SL-C is being used. For such regulations, contact directly the regulatory agency responsible for occupational safety and health in your country
or region.
• Depending on the type of machine to which the SL-C is to be attached, there may be special safety
regulations related to the use, installation, maintenance, and operation of the device, and such safety
regulations must be followed. The responsible personnel must install the SL-C in strict compliance with
such safety regulations.
• The responsible personnel must train the assigned personnel for the correct use, installation, maintenance, and operation of the SL-C. “Machine operators” refers to personnel who have received appropriate training from the responsible personnel and are qualified to operate the device correctly.
• Machine operators must receive specialized training for the SL-C and must understand and follow the
safety regulations for the country or region in which they are using the SL-C.
• When the SL-C fails to operate properly, machine operators must immediately stop the use of the device
and report this fact to the responsible personnel.
• The SL-C is designed with the assumption that it would be properly installed in accordance with the
installation procedures described in this instruction manual and operated according to the instructions in
this instruction manual. Perform an appropriate installation of the SL-C after conducting a sufficient risk
assessment for the target machine.
• This device should be processed as an industrial waste product when being disposed.
iii
3. Warning
■ Operators
• In order for the SL-C to operate properly, the responsible personnel and machine operators must follow
all procedures described in this instruction manual.
• No person other than the responsible personnel and machine operators should be allowed to install or
test the SL-C.
• When performing electrical wiring, always follow electrical standards and regulations for the country or
region in which the SL-C is being used.
■ Usage environment
• Do not use the device in an environment (temperature, humidity, interfering light, etc.) that does not
conform to the specifications contained in this instruction manual.
• Do not use wireless devices such as cellular phones or transceivers in the vicinity of the SL-C.
• The SL-C is not designed to be explosion-proof. Never use it in the presence of flammable or explosive
gases or elements.
• Do not use the SL-C in the presence of substances, such as heavy smoke, particulate matter, or corro-
sive chemical agents, that may induce deterioration in product quality.
• Install the SL-C in such a way so that no direct or indirect light from inverter-type fluorescent lights
(rapid-start type lights, high-frequency operation type lights, etc.) shine on the device.
■ Target machine
• The SL-C has not undergone the model certification examination in accordance with Article 44-2 of the
Japanese Industrial Safety and Health Law. The SL-C, 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-C is to be installed must be susceptible to an emergency stop at all
operating points during its operation cycle. Do not use the SL-C for machines with irregular stop times.
• Do not use the SL-C for power presses equipped with full-revolution clutches.
• Do not use the SL-C 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-C is designed to protect people or objects from entering a machine's hazardous zone or hazard.
It cannot provide protection against objects or materials that are displaced from the machine's hazardous zone or hazard, and so implement additional safety measures such as installing safeguards when
there is the possibility of such displacements.
iv
ENGLISH
■ Installation
• The SL-C must be installed only after securing the minimum safety distance between the SL-C and the
hazardous zone or hazard as established by the applicable regulations of the country or region in which
the SL-C is being used.
• Choose locations for the installation of SL-C transmitters and receivers so that they are not subject to
the effects of light reflected from glossy surfaces in the area.
• Use the same models (same beam axis) for transmitter/receiver pairs.
• The SL-C must be installed in such a way that machine operators cannot reach the hazardous zones or
hazards of the machine without passing through the SL-C's detection zone. Strictly avoid installations
which allow machine operators to access the area between the SL-C and the machine, or where machine operators can approach the machine's hazardous zones, without passing through the SL-C's
detection zone.
• Always perform tests after installing the SL-C in accordance with the test procedures established in this
instruction manual, verifying that the test pieces are detected in all of the detection zones.
• When the Intelligent Extension Unit (SL-R12EX) is used to enable the fixed blanking function, additional
safety measures must be implemented for the zone in which that function is enabled so that it is impossible to reach the hazardous zone or hazards of the machine by passing through that zone. This function cannot be used with SL-C**L having the detection capability of 45 mm diameter.
• When the Intelligent Extension Unit (SL-R12EX) is used to enable the floating blanking function, the
minimum safety distance will be affected due to the fact that the function has a negative effect on the
detection capability. Therefore, in such cases, calculate the minimum safety distance using the new
value for detection capability with the floating blanking function enabled and apply the result for the SLC installation. This function cannot be used with SL-C**L having the detection capability of 45 mm
diameter.
• When the Intelligent Extension Unit (SL-R12EX) is used to enable the floating blanking function, confirm
that the actual number of beam axes with which the floating blanking function is active matches the
number of beam axes specified in the floating blanking function setting. This function cannot be used
with SL-C**L having the detection capability of 45 mm diameter.
• When the Blanking Blind Protection Unit (SL-C08SB/SL-C16SB) is used to install the SL-C, a test must
be carried out according to the procedures described in this instruction manual to confirm that the test
piece can be detected in all detection zones including the detection zone that can be detected by the
Blanking Blind Protection Unit. This function cannot be used with SL-C**L having the detection capability of 45 mm diameter.
• Securely tighten mounting brackets and cord (cable) connectors used in the installation of the SL-C in
accordance with the torque values established in this instruction manual.
ENGLISH
English
4. Circuit Design and Wiring
• Always turn off the device power when performing electrical wiring.
• Follow electrical standards and regulations for the country or region in which the SL-C is being used when
performing the electrical wiring. Only qualified persons should perform wiring.
• Do not place any cables or electrical lines used in wiring the SL-C in the same duct as high-voltage
electrical or power lines or in parallel with such lines.
• Do not extend transmitter and receiver cables over a maximum distance of 30 meters (98.43 ft.).
• Install the mechanism used to reset the interlock (switches, etc.) in a position from which the condition of
the entire hazardous zone can be checked. Do not install the reset mechanism in a position where it can
be operated within the hazardous zone.
• The control outputs (OSSD for SL-C Series or FSD for SL-R11) of the two systems provided in the SL-C
must both be used to build a safety system. Building a safety system with just one of these systems
cannot stop the machine due to a control output malfunction and can result in a serious accident, including serious injury or death to the machine operator.
5. Testing and Maintenance
• Always perform testing in accordance with the test procedures after maintenance, adjustment, or calibration of the target machine or the SL-C, and before the machine start-up.
• If the SL-C does not operate properly when tested in accordance with the test procedures established in
this instruction manual, do not operate the machine.
• Periodically examine the machine to verify that all brakes, other stop mechanisms, and control devices
operate reliably and accurately in addition to checking the SL-C.
• The responsible personnel must perform maintenance procedures as established in this instruction
manual at least once every six months to ensure safe device operation.
