Precautions for Safe Use • Turn OFF the G9SA-300-SC before wiring the G9SA-300-SC. Do not touch the terminals of the G9SA-300-SC while the power is turned ON, because the terminals are charged and may cause an electric shock. • To conform to IEC61496-1 and UL508 when using the F3SJ ensure that the DC power supply satisfies all the conditions below. • The voltage is within the rated power supply voltage range (24 VDC ±10%). • The power supply is connected only to the F3SJ or devices with a direct bearing on the F3SJ’s electrical detection protective function, such as Safety Controllers or Muting Sensors. Do not connect it to any other devices or equipment. When connecting more than one device, ensure that the capacity is easily sufficient for the total rated current. • The power supply conforms to the EMC Directive (industrial environment). • The power supply uses double or reinforced insulation between the primary and secondary circuits. • The power supply automatically resets overcurrent protection characteristics (voltage drop). • The power supply maintains an output holding time of at least 20 ms. • The power supply satisfies the output characteristic requirements of limited voltage/current circuits and Class 2 circuits as defined by UL508. • The power supply satisfies laws, regulations, and standards concerning EMC and the safety of electrical devices for the country or region in which it is used. (In the EU, for example, the power supply must conform to the EMC Directive and Low Voltage Directive.) • Do not connect any device other than the F3SJ-Series with PNP outputs. • Be sure to mount both the emitter and the receiver in the correct position. (The Sensor will not operate it they are mounting in reverse.) • For further details on using the Safety Light Curtains, refer to F3SJSeries User's Manual. Precautions for Correct Use Failure Detection for Slow-starting Power Supply When using a power supply with a long start-up time, if power is switched on while input has been closed the internal circuits will detect a power voltage error and the product will not operate. Apply the voltage to the product once the voltage has reached its rated level. Installation The G9SA-300-SC can be installed in any direction. Wiring • Use the following to wire the Unit. Stranded wire: 0.75 to 1.5 mm2 Solid wire: 1.0 to 1.5 mm2 • Tighten each screw to a torque of 0.78 to 1.18 N·m, or the Unit may malfunction or generate heat. • External inputs connected to H1 and T12 or T21 and T22 of the Unit must be no-voltage contact inputs. • GND is a ground terminal. When a machine is grounded at the positive, the GND terminal cannot be grounded. Connecting Inputs When using more than one G9SA300-SC Unit, do not connect the same switch to more than one G9SA300-SC Unit. This applies to all input terminals. Incorrect T11 T12 T11 T12 G9SA -300-SC G9SA -300-SC Durability of Contact Outputs Relay with Forcibly Guided Contact durability depends greatly on the switching condition. Confirm the actual conditions of operation in which the Relay will be used in order to make sure the permissible number of switching operations. When the accumulated number of operation exceeds its permissible range, it can cause failure of reset of safety control circuit. In such case, please replace the Relay immediately. If the Relay is used continuously without replacing, then it can lead to loss of safety function. Applicable Safety Category (ISO 13849-1) Certified Standards G9SA-300-SC Safety Relay Units fall under PLe/Safety Category 4. The above is provided according to circuit examples presented by OMRON. Therefore, the above may not apply to all operating environments. The applicable safety category is determined from the whole safety control system. Make sure that the whole safety control system meets ISO 13849-1 requirements. The G9SA-300-SC conforms to the following standards. • EN standards, certified by TÜV Rheinland ISO 13849-1 EN60204-1 • Conformance to EMC (Electromagnetic Compatibility), certified by TÜV Rheinland: EMI (Emission): EN55011 Group 1 Class A EMS (Immunity): EN61000-6-2 • UL standards: UL508 (Industrial Control Equipment) • CSA standards: CSA C22.2 No. 14 (Industrial Control Equipment) 8 Terms and Conditions Agreement Read and understand this catalog.
