Precaution for Safe Use Meanings of Signal Words The following signal words are used in this manual. WARNING Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant property damage. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction, or undesirable effects on product performance. Meaning of Alert Symbols Indicates prohibited actions Indicates mandatory actions !WARNING Serious injury may possibly occur due to breakdown of safety outputs. Do not connect loads beyond the rated value to the safety outputs. Serious injury may possibly occur due to loss of required safety functions. Wire G9SA properly so that supply voltages or voltages for loads do NOT touch the safety inputs accidentally or unintentionally. Precautions for Safe Use (1) When ready for wiring, the power source should be disconnected first. Further, at operating this unit, the terminal cover should be closed correctly in order to prevent an electrical shock. (2) Do not wire in case threat of Lightning. otherwise an electric shock may occur. (3) Do not apply any excessive voltage or current to the input or output circuit the G9SA. Doing so may result in damage to the G9SA or cause a fire. (4) Do not apply any variable voltage, otherwise G9SA may malfunction. (5) Do not connect any overload to the output circuit, otherwise the G9SA in operation will generate excessive heat and the output elements of the G9SA may short-circuit or fire may result. (6) The lifetime of G9SA depends on the conditions of switching of its outputs. Be sure to conduct its test operation under actual operating conditions in advance and use it within appropriate switching cycles. Change the G9SA before expected operation. Over operation may cause may short-circuit or may malfunction. (7) Do not operate the G9SA with flammable or explosive gass. An arc with operation and the heat of relay will cause a fire or an explosion. (8) Do not disassemble, repair, or modify the G9SA, otherwise an electric shock may occur or the G9SA may malfunction. (9) Use protective device (Fuse of 5 A current rating etc) for shortcircuit protection and ground fault protection, otherwise a fire may occur or the G9SA may malfunction. Precautions for Correct Use (1) For malfunctions in case that the power supply picks up gradually Malfunctions in case that the power supply picks up gradually. In case that the input circuits close before the power supplies, internal logic may malfunction. (2) Handling 1. Do not drop the G9SA or shock or vibrate the G9SA excessively. Doing so may result in damage to the G9SA or cause G9SA to malfunction. 2. Do not turn the off-delay setting volume switch of G9SA-321T@ less than the MIN value or more than the MAX value. Otherwise the G9SA may be failed. (3) For adhesion of solvent Adhesion of solvent, likely Alcohol, Thinner, Trichloroethane, Gasoline, on the product should be prohibited. Such solvent cause erasing the marking and being inferior of the parts. (4) Operating and Storage Environment Do not operate or store the G9SA under the following conditions. Doing so may result in damage to the G9SA or cause the G9SA to malfunction. 1. The places with direct sunlight. 2. The places with ambient temperature ranges not within -25 to 55C. 3. The places with rapid temperature changes resulting in condensation or relative humidity ranges not within 35 to 85% RH. 4. The places with atmospheric pressure out of the range 86 to 106 kpa. 5. The places with corrosive or inflammable gas. 6. The places with water, oil, or chemical sprayed on the G9SA. 7. The places with vibration or shock affecting the G9SA. 8. The places with atmosphere containing dusts, saline or metal powder. (5) Mounting multiple units When mounting multiple units close to each other, the rated current will be 3 A. Do not apply a current higher than 3 A. (6) For feedback purpose use devices with contacts capable of switching micro loads of 24 VDC, 5 mA. (7) The Safety input OFF signal for T11/T12 (or T23) and T21/T22 terminals must be longer than the response time (10 ms). Otherwise, the G9SA will be locked out or will not be able to be started or restarted. Also, a shorter safety input OFF signal might cause the G9SA to be locked. In this case, all safety inputs must be turned off or the power supply for G9SA must be off before restarting the G9SA. (8) Wiring 1. Use the following to wire the G9SA. * Stranded wire (Flexible wire): 0.75 to 1.5 mm2 * Solid wire: 1.0 to 1.5 mm2 * Maximum Stripping length: 7 to 8mm 2. The G9SA may malfunction or generate heat. * Tighten each screw to a torque of 0.78 to 1.18 N*m 3. External inputs connected to T11 and T12 or T21 and T22 of the G9SA must be no-voltage contact inputs. 4. PE is a ground terminal. When machine is grounded at the positive, the PE terminal should not be grounded. (9) This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference. (10) Mounting Expansion units When an Expansion Unit is being used, remove the connector cover from the G9SA Master Units and insert the connector of the Expansion Unit's connector cable. Make sure that the connector is correctly locked before operating. 15 G9SA Connector Cover Resetting Inputs Do not remove the connector cover of the G9SA-301, G9SA-501, G9SA-321-T@, or G9SA-TH301 unless an Expansion Unit is being used. When only channel 1 of the 2-channel input turns OFF, the safety output is interrupted. In order to restart when this happens, it is necessary to turn OFF and ON both input channels. It is not possible to restart by resetting only channel 1. Connecting Inputs If using multiple G9SA models, inputs cannot be made using the same switch. This is also true for other input terminals. Incorrect T11 T12 T11 T12 G9SA G9SA Resetting Inputs During OFF Delay Time The G9SA-321-T@ operates as follows according to the reset mode when the inputs are to be re-entered during the OFF delay time of the G9SA-321-T@: For auto reset, after the OFF delay time has ended, the outputs will turn OFF, and then the outputs will turn ON again. For manual reset, after the OFF delay time has ended, the outputs will turn OFF, and then the outputs will turn ON again when the reset is input. Durability of Contact Outputs Ground Shorts The G9SA internal circuits have a positive thermistor (TH) built in, which will detect ground short malfunctions (where S1 and S2 are grounded) and 1-channel and 2-channel short malfunctions, and cut off the safety output. If the short breakdown is repaired, the G9SA automatically recovers. Applicable Performance Level (PL) (EN ISO13849-1) G9SA Safety Relay Units can be applied to PLe/Safety Category 4. (The OFF-delay output section of G9SA-321-T@/EX031-T@ is applied to PLd/Safety Category 3.) 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. 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.
