3. Warning
■ Operators
• In order for the SL-R11 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-R11.
• When performing electrical wiring, always follow electrical standards and regulations for the country or
region in which the SL-R11 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-R11.
• The SL-R11 is not designed to be explosion-proof. Never use it in the presence of flammable or explo-
sive gases or elements.
• Do not use the SL-R11 in the presence of substances, such as heavy smoke, particulate matter, or
corrosive chemical agents, that may induce deterioration in product quality.
■ Target machine
• The SL-R11 has not undergone the model certification examination in accordance with Article 44-2 of
the Japanese Industrial Safety and Health Law. The SL-R11, 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-R11 is to be installed must be susceptible to an emergency stop at all
operating points during its operation cycle. Do not use the SL-R11 for machines with irregular stop times.
• Do not use the SL-R11 for power presses equipped with full-revolution clutches.
• Do not use the SL-R11 to control (stop forward motion, etc.) trains, cars and other transportation vehi-
cles, aircraft, equipment for use in space, medical devices, or nuclear power generation systems.
• The SL-R11 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.
■ Installation
• Install the SL-R11 inside an enclosure such as a control panel that offers a rating of at least IP54 in
accordance with the IEC 60529 standard.
• The SL-R11 is a special controller unit for the Safety Light Curtain SL-C Series, so be sure to connect it
to the SL-C Series when using it.
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-R11 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-R11 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, includ-
ing serious injury or death to the machine operator.
• The AUX relay output provided in the SL-R11 is not an output for the safety system, so it cannot be used
as a control output (so called FSD) to stop the machine. If using the AUX relay as a relay output to build a
safety system and stop the machine, it could result in the serious injury or death of the machine operator.
• The FSD relays provided in the SL-R11 can be replaced, but when making the replacement, the replace-
ment relay circuit board (OP-42364) provided by KEYENCE must be used. If another relay is used for
replacement, the SL-C Series or SL-R11 might malfunction, or a serious accident causing the serious
injury or death of the machine operator might occur.
• When wiring the SL-R11 output terminal to the machine control circuit of a machine containing the SL-C,
check with the machine manufacturer to make sure the wiring is appropriate for the machine being used
to ensure that the machine can be stopped correctly. If the wiring is not done correctly for the machine, a
serious accident, such as serious injury or death to the machine operator could result.
