Alert Statements

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.
Do not use G9SX-SM in the system where plurality of motors are driven by one inverter or contactor.

Serious injury may possibly occur due to loss of required safety functions.
Wire G9SX properly so that supply voltages or voltages for loads do NOT touch safety outputs accidentally or unintentionally.

Serious injury may possibly occur due to damages of safety outputs.
Apply protection circuitry against back electromotive force in case connecting inductive loads to safety outputs.

Serious injury may occur due to failure of safety functions. Operate the motor at rated G9SX-SM input frequency (120Hz) or less.

Serious injury may possibly occur due to loss of safety functions.
Use appropriate devices referring to the information provided below.

1. Use G9SX-SM□ within an enclosure with IP54 protection or higher according to IEC/EN60529. Be sure to connect the encloseure to earth(PE).
2. Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of G9SX-SM□ before using the system in which G9SX-SM□ is incorporated.
3. Do not apply DC voltages exceeding the rated voltages, nor any AC voltages to G9SX-SM□.
4. Use DC supply satisfying requirements below to prevent electric shock.
   • DC power supply with double or reinforced insulation, for example, according to IEC/EN60950 or EN50178 or a transformer according to IEC/EN61558.
   • DC supply satisfies the requirement for class 2 circuits or limited voltage/current circuit stated in UL 508.
5. Apply properly specified voltages to G9SX-SM□ inputs.
   Applying inappropriate voltages cause G9SX-SM□ to fail to perform its specified function, which leads to the loss of safety functions or damages to G9SX-SM□.
6. Auxiliary error outputs and auxiliary monitoring outputs are NOT safety outputs. Do not use auxiliary outputs as any safety output
   Such incorrect use causes loss of safety function of G9SX-SM□ and its relevant system.
7. After installation of G9SX-SM□, qualified personnel should confirm the installation, and should conduct test operations and maintenance. The qualified personnel should be qualified and authorized to secure the safety on each phases of design, installation, running, maintenance and disposal of system.
8. A person in charge, who is familiar to the machine in which G9SX-SM□ is to be installed, should conduct and verify the installation.
9. G9SX-SM□ determines that motor stops when the standstill detection input voltage is predetermined value or less. According to the characteristic or load condition of motor, it may turn on safety detection outputs before motor stops completely. In that case, before operation, the qualified personnel should verify that risk of the rotation condition after output is acceptable.
10. Perform daily and 6-month inspections for the G9SX-SM□. Otherwise, the system may fail to work properly, resulting in serious injury.
11. Do not dismantle, repair, or modify G9SX-SM□. It may lead to loss of its safety functions.
12. Use only appropriate components or devices complying with relevant safety standards corresponding to the required level of safety categories.
    Conformity to requirements of safety category is determined as an entire system.
    It is recommended to consult a certification body regarding assessment of conformity to the required safety level.
13. OMRON shall not be responsible for conformity with any safety standards regarding to customer's entire system.
14. Disconnect G9SX-SM□ from power supply when wiring. Devices connected to G9SX-SM□ may operate unexpectedly.
15. Be cautious not to have your fingers caught when attaching terminal sockets to the plugs on G9SX-SM□.
16. Do not use in combustible gases or explosive gases.
17. Driving voltage of the motor is impressed to the standstill detection inputs. Connect overcurrent protective equipment; fuse, circuit-breaker etc., (3A Max.) and tighten the wirings by rated tightening torque to the standstill detection inputs.

Precautions for Correct Use

1. Handle with care
   Do not drop G9SX-SM□ to the ground or expose to excessive vibration or mechanical shocks. G9SX-SM□ may be damaged and may not function properly.
2. Conditions of storage and usage
   Do not store or use in such conditions stated below.
   1. In direct sunlight
   2. At ambient temperatures out of the range of -10 to 55 ℃
   3. At relative humidity out of the range of 25% to 85% or under such temperature change that causes condensation.
   4. In corrosive or combustible gases
   5. With vibration or mechanical shocks out of the rated values.
   6. Under splashing of water, oil, chemicals
   7. In the atmosphere containing dust, saline or metal powder.
      G9SX-SM□ may be damaged and may not function properly.
3. Mounting
   Mount G9SX to DIN rails with attachments (TYPE PFP-M, not incorporated to this product), not to drop out of rails by vibration etc. especially when the length of DIN railing is short compared to the widths of G9SX.
   Do not use G9SX-SM□ at altitudes over 1,000 meters
4. Following spacing around G9SX should be available to apply rated current to outputs of G9SX and for enough ventilation and wiring:
   1. At least 25 mm beside side faces of G9SX.
   2. At least 50 mm above top face of G9SX and below bottom face of G9SX.
      
      
5. Wiring
   1. For model G9SX-SM□
      Use the following to wire to G9SX-SM□.
   • Solid wire: 0.2 to 2.5mm² AWG24 to AWG12
   • Stranded wire (Flexible wire): 0.2 to 2.5mm² AWG24 to AWG12
     Strip the cover of wire no longer than 7mm.
   2. For model G9SX-SM□-RT (with screw terminals)
      Tighten each screw with a specified torque of 0.5 to 0.6N・m, or the
      G9SX-SM□ may malfunction or generate heat.
6. Use cables with length less than 100m to connect to standstill detection Inputs and EDM input respectively.
7. Driving voltage of the motor is impressed to the standstill detection input and there is a possibility that a high level of noise is superimposed. The line of the standstill input must be separately installed from other signal lines.
8. Set the time duration of Standstill detection time to an appropriate value that does not cause the loss of safety function of system.
9. Tuning mode in User configuration is only for adjusting the Standstill determining time. In Tuning mode, auxiliary monitor output is enable however Safety Standstill detection outputs are not enabled. After the tuning is complete, be sure to change from Tuning mode to Monitoring mode for actual operation.
10. Safety standstill detection outputs are only for controlling a guard lock safety-door switch with mechanical lock. They can not be used as safety outputs to drive contactors, or to control a guard lock safety-door switch with solenoid lock.
11. To determine safety distance to hazards, take into account the delay of safety standstill detection outputs caused by the response time
12. Start entire system after more than 5s have passed since applying supply voltage to all G9SXs in the system.
13. G9SX-SM□ may malfunction due to electro-magnetic disturbances.
    Be sure to connect the terminal A2 to ground.
14. 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.
15. Devices connected to G9SX-SM□ may operate unexpectedly. When replacing G9SX-SM□, disconnect it from power supply.
16. Adhesion of solvent such as alcohol, thinner, trichloroethane or gasoline on the product should be avoided. Such solvents make the marking on G9SX-SM□ illegible and cause deterioration of parts.
17. Connectable motor
    AC induction motors can be connected to the G9SX-SM□. Servo motors cannot be connected.
    When a motor with AC240V or more is used, connect neutralpoint of the power supplay to earth.
18. G9SX-SM□ does not have motor fault detective function or motor protective function. For motor protection, use designated external protective devices.
19. For use with inverter
    The dynamic break setting time should be set to 30 seconds or shorter. Otherwise, the G9SX-SM□ may detect a disconnect fault of the wiring.
    Also in the following cases, the standstill detection function may not properly work even while the motor is in standstill.
    1. An inverter with a large output residual voltage is used, and the contactor connected in serial with the inverter is in the ON state.
    2. The inverter is executing the auto tuning function.
