Introduction
This User’s Guide describes the usage of the G9SX Series-Flexible Safety Units mainly through application
examples.
Humans make mistakes and machines fail.
Therefore it is necessary to design machines and equipment based on the assumption that humans will make
mistakes and machines will fail.
Thus, a circuit configuration is required to ensure safety, even when an onsite operator makes a mistake in machine
operation or when a part of the machine fails. Flexible Safety Units, which enable various safety circuit patterns to be
configured only by simple wiring, provide the core components of such safety circuits.
Use the OMRON Flexible Safety Units in your machine and equipment to improve the safety designs and onsite
worker safety measures.

2-5 Connecting Safety Sensors and the G9SX
( 1 ) When connecting safety sensors to the G9SX, the Y1 terminal must be connected to 24 VDC.
The G9SX will detect a connection error, if the Y1 terminal is open.
( 2 ) In many cases, safety sensor outputs include an OFF-shot pulse for self diagnosis.
The following condition of test pulse is applicable as safety inputs for the G9SX.
• OFF-shot pulse width of the sensor, during the ON-state: 340 μs max.

2-10 Connecting Expansion Units
• G9SX-EX/G9SX-EX-T Expansion Units can be connected to the G9SX-AD/-ADA Advanced Unit, G9SX-NSA
Non-contact Door Switch Controller, or G9SX-GS Safety Guard Switching Unit to increase the number of safety
outputs. (Expansion Units cannot be connected to the G9SX-BC or to the G9SX-NS Non-contact Door Switch
Controller.)
• A maximum of five Expansion Units can be connected to one Advanced Unit. This may be a combination of
G9SX-EX Instantaneous types and G9SX-EX-T OFF-delayed types.
• Remove the end connector from the Unit (G9SX-AD, G9SX-ADA, G9SX-NSA, or G9SX-GS) and insert the
connector on the Connecting Cable from the first Expansion Unit. Place the end connector that was removed from
the Unit on the last Expansion Unit (i.e., the rightmost Expansion Unit).
• When Expansion Units are connected to an Advanced Unit, make sure that power is supplied to every Expansion
Unit. (Refer to the following diagram for actual Expansion Unit connection.)

2. Logical AND Connections
The logical AND connection is used to build logic between multiple safety inputs and safety outputs. This technology
is unique to the G9SX Series.
■ Logical AND Connection Signals
Pulse signals are used in the G9SX logical AND connection and dynamic processing is used to monitor the signals.
Information on safety between Units is passed by these pulse signals, which are also used to detect faults in the
connection and short circuits.

Safety Precautions
Safety Distance
The safety distance is the minimum distance that must be
provided between the safety input device and a machine's
hazardous part to stop the hazardous part before a person or
object reaches it. The safety distance varies according to the
standards of each country and the specifications of each machine.
In addition, the calculation of the safety distance differs if the
direction of approach is not perpendicular to the detection zone of
the safety input device. Always refer to the relevant standards.
Safety Distance Concepts
( 1 ) To determine the approach speed K1, consider all factors,
including the operator's physical abilities.
( 2 ) To determine the maximum approach speed K2, consult
with a notified body or other authoritative institutes.
( 3 ) The response time of a machine is the time from when the
machine receives a stop signal to the time when the
machine's hazardous part stops. Measure the response
time on the actual system. Also, periodically check that the
machine's response time has not changed.
( 4 ) For information on the response time of the G9SX system,
refer to item 10 of Precautions for Correct Use on page 98.

( 1 ) Use G9SX within an enclosure with IP54 protection or
higher of IEC/EN60529.
( 2 ) Incorrect wiring may lead to loss of safety function. Wire
conductors correctly and verify the operation of G9SX before
commissioning the system in which G9SX is incorporated.
( 3 ) Do not apply DC voltages exceeding the rated voltages, or
any AC voltages to the G9SX 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 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 inputs.
Applying inappropriate voltages cause G9SX to fail to
perform its specified function, which leads to the loss of
safety functions or damages to G9SX.
( 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
and its relevant system.
Also Logical AND connection outputs can only be used for
logical AND connections between G9SXs.
( 7 ) After installation of G9SX, 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
is to be installed, should conduct and verify the installation.
( 9 ) Perform daily and 6-month inspections on the G9SX.
Otherwise, the system may fail to work properly, resulting in
serious injury.
(10) Do not dismantle, repair, or modify G9SX. It may lead to
loss of its safety functions.
(11) 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.
(12) OMRON shall not be responsible for conformity with any
safety standards regarding to customer's entire system.
(13) Disconnect G9SX from power supply when wiring, to
prevent electric shock or unexpected operation.
Doing so may lead to the loss of its safety functions.
(14) Be cautious not to have your fingers caught when attaching
terminal sockets to the plugs on G9SX.
(15) Do not use in combustible gases or explosive gases.
97
Safety Precautions
<G9SX-GS@>
( 1 ) Be sure to correctly connect safety input devices to safety
input A and safety input B to ensure proper operation of the
safety functions.
( 2 ) When setting the Switching Function, be sure to consider
safety control requirements, safety level and safety
category of the entire system.
( 3 ) A qualified personnel who has a thorough understanding of
the installed machine must switch the mode selector input.
For example, a Switching Unit with Key must be used for
the mode selector, and the key must be managed and used
in such a way that the machine cannot be operated by
unauthorized persons.
( 5 ) Wiring
1. G9SX
• Wire the G9SX as described below.

USER'S GUIDE
Solid wire
0.2 to 2.5 mm2 (AWG24 to AWG12)
Stranded wire
0.2 to 2.5 mm2 (AWG24 to AWG12)
• Strip no more than 7 mm of insulation from the end of
the wire.
• It is recommended that stranded wire be covered with
insulated 0.25- to 2.5-mm2 ferrules before connecting it.
2. G9SX-@-RT (with Screw Terminals)
• Tighten each screw to 0.5 to 0.6 N·m or the G9SX-@RT may malfunction or generate heat.
3. Wiring for a Logical AND Connection
• Use a 2-conductor cabtire cable or shielded cable to
wire a logical AND connection between Units.
Connecting Expansion Units (G9SX-EX@-@):
(Only G9SX-AD@/-ADA@/-NSA@/-GS@)
1. Remove the termination connector from the G9SX, and
insert the connector of the Expansion Unit into the
G9SX to connect it.
2. Insert the termination connector into the last Expansion
Unit as viewed from the G9SX. When the G9SX is used
without any Expansion Units, do not remove the
termination connector from the G9SX.
3. Do not remove the termination connector while the
system is operating.
4. Before applying the power supply voltage, confirm that
the connecting sockets and plugs are locked.
5. Make sure that all connected Expansion Units are
supplied with power within 10 s after the power to the
G9SX is turned ON. Otherwise, the G9SX will detect a
power supply error for the Expansion Units.
Use cables with length less than 100m to connect to Safety
Inputs, Feed-back/Reset inputs, or between Logical AND
connection inputs and Logical AND connection outputs,
respectively.
Set the time duration of OFF-delay to an appropriate value
that does not cause the loss of safety function of system.
Logical AND connection between Units:
1. When using Logical AND connection inputs, set the
Logical AND connection preset switch to 'AND' position
for the units which the logical AND connection signal
are input to.
2. Connect Logical AND connection outputs appropriately
to Logical AND connection inputs of the relevant unit.
Verify the operation of G9SX before commissioning the
system.
3. When configuring the safety related system, be sure to
consider that the delay of response time caused by
logical AND connections do not degrade the safety
function of the system.
4. Use 2-conductor cabtire cable or shielded cable for
logical AND connections between Units.
To determine the safety distance to hazards, take into
account the delay of safety outputs caused by the following
times:
1. Response time of safety inputs
2. Response time of logical AND connection input
(Also consider the precaution in "Note" below)
3. Preset OFF-delay time
4. Accuracy of OFF-delay time
Note: When connecting multiple Units with logical AND
connections, the operating time and response time
after logical AND connection inputs will be the sum
of the operating times and response times of the
Units that are connected in series by logical AND
connections.
Start entire system after more than 5s have passed since
applying supply voltage to all G9SXs in the system.
Safety Precautions
(12) Power Supply
1. The G9SX may malfunction due to electromagnetic
disturbances. Be sure to connect terminal A2 to ground.
2. When sharing a power supply with a Safety Light
Curtain, use a power supply that will not fail for a
momentary power interruption of 20 ms or less.
(13) Devices connected to G9SX may operate unexpectedly.
When replacing G9SX, disconnect it from power supply.
(14) Adhesion of solvent such as alcohol, thinner,
trichloroethane or gasoline on the product should be
avoided. Such solvents make the marking on G9SX
illegible and cause deterioration of parts.
<G9SX-NS/-NSA, D40A>
For details, refer to D40A/G9SX-NS catalog (Cat. No. C160).
( 1 ) Connection with Non-contact Door Switch
Wire conductors between the G9SX-NS@ and the D40A
Non-contact Door Switch correctly and verify operation,
before using the system.
( 2 ) The D40A must be used with a designated actuator and
G9SX-NS@ Controller.
( 3 ) Use cables with a length of less than 100 m total to connect
D40A Switches.
(11) Check that the machine is stopped whenever the
interlocked guard door is open.
(12) Do not mount the switch and actuator on magnetic
materials, otherwise it may affect the operating distance.
Below are reference values of the effect to the operating
distance.
Distance from surface of
magnetic material
Operating distance
0 to 5 mm
Decrease to approx. 90% of
rated value.
> 5 mm
No effect
(13) Tighten all screws to the specified torque by using nonmagnetic M4 screws and washer for the installation of the
switch and actuator. After installation and using, the
actuator and switch fixing screws must be coated with
tamper proof varnish or similar compound. Using
anaerobic locking compounds can have a detrimental
effect on the plastic switch case if the compounds come
into contact with the switch case.

(14) Wiring
1. Use the following to wire to the product.
Stranded wire (flexible wire): 0.2 to 2.5 mm2 (AWG24 to
AWG12)
Solid wire (steel wire): 0.2 to 2.5 mm2 (AWG24 to
AWG12)
2. When an auxiliary output is not used, cut off the wiring
and cover it with tape so that it does not contact other
terminals.
<G9SX-GS>
( 1 ) Use a mode selector that has an SPST-NO + SPST-NC
contact form (e.g., OMRON's A22K-@-11).
Precautions
( 4 ) Disconnect the G9SX-NS@ from the power supply when
replacing the D40A. Devices connected to the G9SX-NS@
may operate unexpectedly.
( 5 ) Do not use the D40A in a magnetic field of 1.5 mT or
higher. The D40A may not function properly.
( 6 ) Do not use the D40A in the water or in an environment
continuously exposed to water. Water may penetrate into
the D40A. (The IP67 degree of protection for this switch
means that it has been checked for penetration of water
after having been left in water for a fixed period of time.)
( 7 ) Be sure to mount a guard stopper and guide to prevent the
D40A Non-contact Door Switch from being subjected to
impact.
( 8 ) Do not use the switch or actuator as a stopper. Protect the
switch and the actuator by installing a stopper. Separate
the switch and the actuator to a distance of 1 mm or more.
( 9 ) Install the actuator and switch at an appropriate distance
so that they do not create a gap that provides access to the
hazard.
(10) Where two or more Switches are mounted side-by-side,
they must be no closer than 25 mm.
