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.
To turn on safety standstill detection outputs, ONstate signals should be input to T32. Otherwise,

G9SX-SM
Functions
Configuration and Mode
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 10 mV or less, it will turn on safety standstill detection outputs, determining
the motor is in a standstill condition.
In Standard Configuration, any settings with the Mode preset switch on the back of the unit and both of the Standstill determining time preset
switches on the front and on the back of the unit are disabled.
User Configuration
When G9SX-SM detects that the standstill detection input voltage has been 100 mV 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.
Mode name

NOT turned ON.
In this mode, G9SX-SM operation depends on the "DET TIME switches (the
standstill determining time preset switches)", one each on the front side and
Use this mode in normal operation after the
the back side.
Monitoring Mode
Standstill determining time is fixed.
The DET TIME (standstill determining time) setting values come into effect
at power on.
* 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.
Operation Preset switch/Mode Preset switch
Standstill Determining Time Preset Switch
Use switches on the back side of the unit for operation preset and
mode preset.
Manipulation of preset switches must be done while the power is off.

Configuration is made through switches on the front and back side of
the unit. Operation can be normal only if both switch values are the
same.If the values are different, an error occurs.

Control
Devices
Requirements
Guard lock
Safety-door
Switch
Use certified devices with Direct Opening
Mechanism complying with IEC/EN 60947-5-1
Use approved devices with Direct Opening
Mechanism complying with IEC/EN 60947-5-1,
mechanical lock type and capable of solenoid coil
24VDC, less than 300mA.
Safety Relay
Use certified devices with forcibly guided contacts
complying with EN 50205.
For feedback purpose use devices with contacts
capable of switching micro loads of 24VDC, 5mA.

satisfy the requirements of safety category level.
Precautions for Safe Use
1. Use G9SX-SM@ within an enclosure with IP54 protection or higher
of IEC/EN60529. Be sure to connect the enclosure to earth (PE).
2. Incorrect wiring may lead to loss of safety function. Wire
conductors correctly and verify the operation of G9SX-SM@
before commissioning the system in which G9SX-SM@ is
incorporated.
3. Do not apply DC voltages exceeding the rated voltages, or any AC
voltages to the G9SX-SM@ power supply input.
4. Use DC supply satisfying requirements below to prevent electric
shock.
• DC power supply with double or reinforced insulation, for example, according to IED/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 G9SXSM@ 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, to
prevent electric shock or unexpected operation.
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, circuitbreaker etc. (3A Max.) and tighten the wirings by rated tightening
torque to the standstill detection inputs.

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 determining 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 enabled 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
