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 Safe Use
(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 2.5mm2AWG24 to AWG12
-Stranded wire (Flexible wire): 0.2 to 2.5mm2AWG24 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 neutral point
of the power supply 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.
(20) Operate the reset input more than 0.4 seconds immediately after
the safety outputs are OFF.
G9SX-SMdoes not accept the reset input from when the
outputs are turned ON and until 0.4 seconds passes after the
outputs are turned OFF.

Mode
Use this mode to adjust the Standstill
determining time.
This mode is only for adjusting the Standstill
determining time. (*1)
Use this mode in normal operation after the
Standstill determining time is fixed.
To preset the Standstill determining time, use the "DET TIME switch (the
Standstill determining time Preset switch)" on the front side.
Once the DET TIME setting is changed, the new setting immediately
comes into effect on the system without having to perform a power cycle.
When a standstill condition is detected, the Auxiliary Monitor output is
turned on and the ES Indicator is lit, but Safety standstill detection outputs
are NOT turned on.
In this mode, G9SX-SM operation depends on the "DETTIME switches",
one each on the front side and the back side. The DET TIME setting
values come into effect at power on.
*1. If the optimal Standstill determining time is already known, the value can be applied to the Monitoring Mode, without having to use
the Tuning Mode.
Functions

Use the "Operation Preset switch" on the back side to select either Standard Configuration or User Configuration. The selected configuration mode is enabled at
power-on.
-
Normally, please use Standard Configuration which is set as factory default.
-
If the Standstill determining time is found too long in the Standard Configuration mode, switch to User Configuration and adjust the Standstill determining time.
Standard Configuration
When G9SX-SM detects that the standstill detection input voltage is 10mV or less, it will turn on safety detection outputs, determining the motor is in a
standstill condition.
In Standard Configuration, any settings with the "Mode Preset switch" and both of the "Standstill Detection Time Preset switches" are disabled.
User Configuration
When G9SX-SM detects that the standstill detection input voltage has been 100mV or less for a predetermined Standstill determining time or longer, or when
G9SX-SM detects that the standstill detection input voltage has been 10mV or less, it will turn on safety standstill detection outputs, determining the motor is
in a standstill condition.
In User Configuration, two modes are available: Tuning mode (TUN) and Monitoring mode (MON). Either can be selected by setting the "Mode Preset
switch".
The selected mode is applied at power-on.

To turn on the Safety standstill detection
outputs,both Standstill detection inputs must
be below the threshold voltage. Otherwise,
Safety standstill detection outputs will NOT be
turned ON.
When the wiring between the motor and
G9SX-SMbreaks, G9SX-SMdetects it as
failure of the wiring or continues to operated
as motor is rotating, regardless of the status
of motor.Thus the breakage of wiring does
not lead to a dangerous situation.
Connect the power source to the A1 and A2
terminals. Connect the power supply plus to the A1 terminal.
Connect the power supply minus to the A2 terminal.

The G9SX-SMcan be used for PL=e and Category 4 required by EN ISO 13849-1 European standard.
Refer to the following link for the Safety-related characteristic data:
http://www.fa.omron.co.jp/safety_6en/
This does NOT mean that G9SX-SM can always be used for required category under all the similar conditions and situations.
Conformity to the categories must be assessed as a whole system.
When using G9SX-SM for safety categories, be sure to confirm the conformity as a whole system.
For conformity to Safety Category 4, please check the following points;
1) Connect a fuse to each of the Standstill detection input lines.
2) Provide signals of different phases for the Standstill detection inputs (Z1-Z2, Z3-Z4).
3) Connect Guard lock Safety-door switches to any one of Safety Standstill detection outputs: ES1, ES2 or ES3.
4) Input the signal through a NC contact of the contactor to EDM input T31-T32.(Refer to '6. Application Examples')
5) Be sure to connect A2 to ground.
