A logical AND connection means that one unit (Unit
A) outputs a safety signal “a” to a subsequent unit
(Unit B) and Unit B calculates the logical
multiplication (AND) (i.e., outputs the AND) of the
signal “a” and safety signal “b”, which is input to Unit
B.
Thereby the logic of the safety output of Unit B is “a”
AND “b”. (An AND of inputs “a” and “b” is output.)
To set the safety outputs of the subsequent Unit in the
ON state, its logical AND connection preset switch
must be set to AND (enable) and the HIGH state
signal must be input to T41 of the subsequent unit.

Logical AND Connection
● Example with G9SX-AD322-@
● Example with G9SX-ADA222-@
The logical AND connection means that the Basic Unit (or Advanced
Unit) outputs a safety signal “a” to an Advanced Unit, and the
Advanced Unit calculates the logical multiplication (AND) of the safety
signal “a” and safety signal “b.” The safety output of an Advanced Unit
with the logical AND connection shown in the following diagram is “a”
AND “b”.
The Advanced Unit G9SX-ADA222-@ is equipped with two logical
AND connection inputs. Therefore, it is capable of receiving two
safety signals, each from different Advanced or Basic Units. As
shown in the diagram below, the output of Advanced Unit
G9SX-ADA222-@ will be “a” AND “b” AND “c”.

This is illustrated using the application in the following diagram as an
example. The equipment here has two hazards identified as Robot 1
and Robot 2, and it is equipped with a safety door switch and an
emergency stop switch. You may have overall control where both
Robot 1 and Robot 2 are stopped every time the emergency stop
switch is pressed. You may also have partial control where only
Robot 1, which is closest to the door, is stopped when the door is
opened. In that case, Robot 2 will continue to operate.
The actual situation using a G9SX for this application is shown in this
example.
(Note: The logical AND setting on the Advanced Unit must be set to
AND (enabled).)

Connecting Expansion Units
• The G9SX-EX and G9SX-EX-T Expansion Units can be connected
to an Advanced Unit (G9SX-AD322-@/G9SX-ADA222-@) to
increase the number of safety outputs. (They cannot be connected
to a Basic Unit.)
• 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 terminating connector from the receptacle on the
Advanced Unit and insert the Expansion Unit cable connector into
the receptacle. Insert the terminating connector into the receptacle
on the Expansion Unit at the very end (rightmost).
• 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.)

Setting Procedure
1.Cross Fault Detection (Advanced Unit/Basic Unit)
Set the cross fault detection mode for safety inputs by shorting Y1 to
24 V or leaving it open. When cross fault detection is set to ON,
short-circuit failures are detected between safety inputs T11-T12 and
T21-22. When a cross fault is detected, the following will occur.
1. The safety outputs and logical AND outputs lock out.
2. The LED error indicator is lit.
3. The error output (auxiliary output) turns ON.

2.Reset Mode (Advanced Unit/Basic Unit)
4.Setting the OFF-delay Time (Advanced Unit)
Set the reset mode using feedback/reset input terminals T31, T32,
and T33.
Auto reset mode is selected when terminal T32 is shorted to 24 V and
manual reset mode is selected when terminal T33 is shorted to 24 V.
The OFF-delay preset time on an Advanced Unit is set from the OFFdelay time preset switch (1 each on the front and back of the Unit).
Normal operation will only occur if both switches are identically set. An
error will occur if the switches are not identically set.
The default setting of the OFF-delay time preset switch is set to 0 s.

● Application Overview
1. When the emergency stop switch S1 is pressed.
• The power supply to the motor M1 and M2 is turned OFF immediately when the emergency stop switch S1 is pressed. Stop command is sent
to the motor controller for the motor M3, and the power supply to the motor M3 is turned OFF after OFF-delay time.
• The power supply to the motor M1 is kept OFF until the emergency stop switch S1 is released and the reset switch S2 is pressed.
• The power supply to the motor M2 and M3 is kept OFF until the guard is closed and the reset switch S2 is pressed while the emergency stop
switch S1 is released.
2. When the guard is opened (the emergency stop switch S1 is released).
• The power supply to the motor M2 is turned OFF immediately when the S3 and S4 detect that the guard is opened. Stop command is sent to the motor
controller for the motor M3, and the power supply to the motor M3 is turned OFF after OFF-delay time. (The power supply to the motor M1 is kept ON.)
• The power supply to the motor M2 and M3 is kept OFF until the guard is closed.

A Safety Measure for Hazardous Operations
That Does Not Lower Productivity
• Two functions support two types of application:
• Auto switching: For applications where operators work
together with machines
• Manual switching: For applications with limited operations
• External indicator outputs enable indicating the switching status
of two safety input devices.
• Auxiliary outputs enable monitoring of safety inputs, safety
outputs, and errors.
• Detailed LED indications enable easy diagnosis.
• Logical AND connection allows complicated applications in
combination with other G9SX-series Units.
• Certification for compliance with IEC/EN 61508 (SIL3), IEC/EN
62061 (SIL3) and EN ISO13849-1 (PLe/Safety Category 4).
Be sure to read the “Safety Precautions” on page 47.

Connecting Safety Sensors and G9SX-GS@
1. To input the control output from safety sensors to the G9SX-GS@,
the Y1 terminal must be connected to 24 VDC when the control
output is connected to channel A. Likewise, the Y2 terminal must
be connected to 24 VDC when the control output is connected to
channel B. The G9SX-GS@ will detect a connection error if these
terminals are not connected to 24 VDC.
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: 500 μs

Auto or manual switching is set by using the Switching Function
setting switch on the bottom of the G9SX-GS@. Set the switch to Auto
for auto switching and Manual for manual switching.
Set the reset mode using feedback/reset input terminals T31, T32,
and T33.
Auto reset mode is selected when terminal T32 is shorted to 24 V and
manual reset mode is selected when terminal T33 is shorted to 24 V.

3.Cross Fault Detection
When connecting a Door Switch or other safety input device, you can use Y1 or Y2 to switch the cross fault detection setting.
When Y1 is open, short-circuit failures are detected between safety inputs T11-T12 and T21-T22. When Y2 is open, short-circuit failures are
detected between safety inputs T61-T62 and T71-T72. When a cross fault is detected, the following will occur.
1. The safety outputs and logical AND output will be locked out.
2. The LED error indicator will light.
3. The error output (auxiliary output) will turn ON.
When a safety sensor, such as a Safety Light Curtain, is connected to safety input A, connect Y1 to 24 V. When a safety sensor is connected to
safety input B, connect Y2 to 24 V. If they are not connected to 24 V, the G9SX-GS@ will detect an error.

4.Diagnostic Checks of External Indicators
6.Setting the OFF-delay Time
Diagnostic checks of external indicators connected to external
indicator outputs UA and UB can be switched with Y3 and Y4,
respectively. Enabling the diagnostic check makes it possible to
detect indicator burnout or wiring errors.
If there is no indicator connected to external indicator output UA,
connect Y3 to 24 V. If there is no indicator connected to external
indicator output UB, connect Y4 to 24 V. If they are not connected to
24 V, the G9SX-GS@ will detect an error.
The OFF-delay preset time is set from the OFF-delay time preset
switch (1 each on the front and back of the Unit).
Normal operation will only occur if both switches are identically set. An
error will occur if the switches are not identically set.
The default setting of the OFF-delay time preset switch is set to 0 s.

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.

Precautions for Safe Use
<Precautions for All G9SX Models>
1. Use G9SX within an enclosure with IP54 protection or higher of
IEC60529.
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,
damages to G9SX, or burning.
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. Inspect the G9SX daily and every six months. Incorrect system
operation may result in serious injury.
10. Do not dismantle, repair, or modify G9SX. It may lead to loss of its
safety functions, creating a dangerous situation.
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.
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.
If a person approaches the detection zone
perpendicularly, calculate the safety distance
as shown below.
S1 = K1 × (Ts + Tc + Tr + Tbm) + Dpf
S2 = K2 × (Ts + Tc + Tr + Tbm) + Dpf
S1: Safety distance 1
Calculating the S2: Safety distance 2
safety distance K1: Approach speed of a person to the
specified by
detection zone (area A)
American
K2: Maximum approach speed of a machine to
standard ANSI
the detection zone (area A)
Ts: Machine's stop time (s)
B11.19
Tr: Response time of the G9SX system from
ON to OFF (s)
Tc: Machine control circuit's maximum response
time required to activate its brake (s)
Tbm:Additional time (s)
Dpf: Additional distance
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 49.

5. Wiring
(1) G9SX
• Wire the G9SX as described below.
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.
(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.
6. 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.
7. Use cables with a length of 100 m maximum to connect the safety
inputs, feedback/reset input, logical AND connection input, logical
AND connection output, or mode selector inputs.
8. Set the time duration of OFF-delay to an appropriate value that
does not cause the loss of safety function of system.
9. 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. Give careful consideration to the response time delay during
logical AND connection in order to prevent any reduction in the
safety of the safety control system.
4. Use two-conductor cabtyre cable or shielded cable for wiring
the logical AND connections between Units.
10. 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 “ * ” below)
(3) Preset OFF-delay time
(4) Accuracy of OFF-delay time
* 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.
50 mm min.

G9SX
11. Start entire system after more than 5 s have passed since
applying supply voltage to all G9SXs in the system.
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.
15. Do NOT mix AC load and DC load to be switched in one G9SXEX@-@. When switching of both AC load and DC load is
necessary, connect more than two G9SX-EX@-@ and use each
unit for AC load and DC load exclusively.
16. Operate the reset input more than 0.4 seconds immediately after
the safety outputs are OFF.
G9SX 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.
<G9SX-GS>
1. Use a mode selector that has an SPST-NO + SPST-NC contact
form (e.g., OMRON’s A22K-@-11).
Safety Category (EN ISO 13849-1)
In the condition shown in Application Examples, G9SX can be used
for the corresponding categories up to Safety category 4 per EN
ISO13849-1.
This does NOT mean that G9SX 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 for safety categories, be sure to confirm the
conformity as a whole system.
Applicable Safety Category 4 (EN ISO13849-1)
1. Input signals to both safety inputs (T11-T12, T21-T22, T61-T62,
and T71-T72).
2. Input signals to the safety inputs (T11-T12, T21-T22, T61-T62, and
T71-T72) through switches equipped with a direct opening
mechanism.
When using limit switches, at least one of them must have a direct
opening mechanism.
3. When connecting a Safety Sensor to the G9SX, use a TYPE 4
Safety Sensor.
4. Input the signal through a NC contact of the contactor to Feedback/
Reset input (T31-T32 for manual reset or T31-T33 for auto reset).
5. Keep the cross fault detection mode input (Y1 and Y2) open.
However, when connecting devices that have a self-diagnosis
function, such as Safety Sensors, apply 24 VDC to Y1 or Y2.
6. Be sure to connect A2 to ground.
7. When using a G9SX-EX@-@ Expansion Unit, connect fuses with a
current rating of 3.15 A maximum to the safety relay outputs to
prevent the contacts from welding.
