• Locations where there are corrosive gases

• Locations where any flammable gases or explosive gases exist

• Locations where the SL-T11R may be directly subjected to vibration or impact

• Locations where strong electromagnetic noises may affect the SL-T11R

■ Tar ge t ma ch in e

Danger

• The SL-T11R has not undergone the model certification examination in accordance with Article 44-2 of the Japanese Industrial Safety and Health Law. The SL-T11R, 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-T11R is to be installed must be susceptible to an emergency stop at all operating points during its operation cycle. Do not use the SL-T11R for machines with irregular stop times.

• Do not use the SL-T11R for power presses equipped with full-revolution clutches.

• The SL-T11R 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-T11R 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.

■ Circuit design and wiring

Danger

• Always turn off the power to the SL-T11R when performing electrical wiring.

• You must fulfill the electrical standards and regulations in the country or region in which the SL-T11R is being used when you perform the electrical wiring.

• To avoid the risk of electric shock, do not connect any of the SL-T11R inputs/outputs except for FSD 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-T11R with reinforced insulation or double insulation except for FSD.

• In order to fulfill the requirements in IEC61496-1, UL61496-1, EN61496-1 and UL508, power supply for the SL-T11R must fulfill the conditions listed below.

A rated output voltage of 24 V DC (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-T11R is used.

• Do not install the electric wiring of the SL-T11R together with or in parallel with high-voltage electrical or power lines.

• Both of the two FSDs provided on the SL-T11R must be used to establish a safety-related machine control system. Establishing a safety-related machine control system with just one of the FSDs cannot stop the machine in the event of an FSD failure and may result in significant harm to the machine operators including serious injury or death.

• 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 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 significant harm to the machine operators, including serious injury or death.

• The transmitter and receiver cables of the SL-V connected to the SL-T11R 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.
