Description of operation
Wiring
Either Safety input or Enabling input is effectively done by
1NC and 1NO inputs.
The relationship between Safety/Enabling input and Mode
selector inputs is as follows:
M1 = ON, M2 = OFF → Safety input is enabled (Normal
operating mode)
M1 = OFF, M2 = ON → Enabling input is enabled
(Maintenance mode)
Normal operating mode: To turn on Safety speed detection
outputs, pulse signals from the two proximity sensors
detection should be 2.0 Hz max.
Maintenance mode: To turn on Safety speed detection
outputs, the signal frequency from the two proximity
sensors should be lower than the low speed detection
settings value.

Connecting Safety Sensors and the G9SX-LM
1. When connecting safety sensors to the G9SX-LM@, the Y1 terminal must be connected to 24VDC for enabling input channel. Or for Safety
input channel, the Y2 terminal must be connected to 24 VDC.
The G9SX-LM@ will detect a connection error, if the Y1 or Y2 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: 500 μs max..

Low-speed Detection Function
Relationship between G9SX-LM outputs (safety instantaneous
outputs and safety speed detection outputs) and inputs (safety input,
enabling input, rotation detection input) differs depends on mode
selector input status.
Converts the pulse signals from two proximity sensors that monitor
the rotation status of hazards to frequency to control the safety speed
detection outputs.
• The diagram below shows the relationship between the Low-speed
detection frequency and Safety speed detection outputs. The
frequency (F) has a tolerance of - 10%.
• This accuracy tolerance does not include any characteristics of
proximity sensors.

Logical AND Connection
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".
Note: 1. To monitor the rotation status of hazards, install a cogwheel
for proximity sensors linked to hazards as follows. For
design of cogwheel and installation of proximity sensors,
see page 13 "Shape of Cogwheel and Setting of Proximity
Sensors".

2. If G9SX-LM@ is operated without proximity sensors being
connected, G9SX-LM@ will detect it as an error.
3. If both sensors do not detect the cogwheel, G9SX-LM@ will
detect it as an error.

• The G9SX-EX and G9SX-EX-T Expansion Units can be connected
to the G9SX-LM@) to increase the number of safety instantaneous
outputs.
• When the G9SX-EX-T is connected, it will operate in the same way
as G9SX-EX.
• A maximum of five Expansion Units can be connected to one
G9SX-LM@. 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
G9SX-LM@ 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.)
Set the reset mode using feedback/reset input terminals T31, T32,

(2) Cross Fault Detection
When connecting safety door switches to safety input and enabling
input, cross fault detection can be switched through the Y1 and Y2
terminals.
When the Y1 terminal is open, a cross fault of enabling inputs
between T11 and T12, and T21 and T22 is detected. When the Y2
terminal is open, a cross fault of safety inputs between T61 and T62,
and T71 and T72 is detected. When a cross fault is detected, the
following conditions occur:

b.The LED error indicator is lit.
c.An error output (auxiliary output) is turned ON.
When connecting safety sensors such as safety light curtains to
enabling input, be sure to connect the Y1 terminal to +24 V. When
connecting safety sensors to safety input, be sure to connect the Y2

Shape of Cogwheel and Setting of Proximity Sensors
1. Installation of proximity sensors
For safe and stable detection of a rotating cogwheel, install proximity sensors according to the following description:
• To avoid interference from surrounding metal and mutual interference, specified proximity sensors should be correctly installed.
• For handling of proximity sensors, see the instruction manual for the E2E.
• Connect two proximity sensors of the same type.
• Install proximity sensors so that one of them is turned ON when the rotation of cogwheel stops.
If neither sensor has detected any movement for one second or longer, G9SX-LM@ will detect it as an error.
Proximity
sensor A
Install proximity sensors so that
one of them is turned ON when
the rotation of cogwheel stops.
Install one proximity sensor on
the center line of the concavity
width, and the other on the
center of the convexity width so
that one of the proximity sensors
will be turned ON when the
rotation of the cogwheel stops.
Proximity
sensor B
With this installation, both
proximity sensors are turned
OFF when the rotation of the
cogwheel stops.
If both sensors are turned OFF
for one second or longer,
G9SX-LM@ will detect it as an
error.
Proximity
sensor B
Proximity
sensor A
• Make sure the cogwheel and proximity sensors mounted properly and not affected vibration from the machine when it is stop condition; otherwise
G9SX-LM@ safety outputs turn off when cogwheel affected machine vibration. Take appropriate measures to keep vibration level to the cogwheel less than or equal to 1Hz.
• G9SX-LM@ diagnoses the proximity sensor at the following condition. The operation indicator on the proximity sensor blinks during this condition.
- The cogwheel is standstill and both proximity sensor inputs are on status.
2. Relationship between the cogwheel shape and the setting of proximity sensors
Design the cogwheel shape according to types of proximity sensors. Use the following provisions as a reference.
• Proximity sensors to be used should be selected based on the max. number of revolutions during normal operation and the number of cogwheel
teeth. See the equation below.
R x 1 / 60 x N < F
R : Max. number of revolutions during normal operation (rpm)
N : Number of cogwheel teeth
F : Response frequency of proximity sensor (Hz)
• Install one proximity sensor on the center line of the concavity width, and the other on the center of the convexity width so that one of the proximity
sensors will be turned ON when the rotation of the cogwheel stops.
• All cogwheel teeth should be identically shaped.
The following tables show data for iron cogwheels. Use of other material will show different characteristics of operating range.
See E2E Catalog for details.

3. Design examples
This example shows a design of cogwheel and proximity sensors when the number of motor revolutions of hazards is 3000 rpm at normal operation
(high speed), and 60 rpm at low speed.
Step 1: Calculating the number of cogwheel teeth
"Input frequency range" and "Low speed detection settings" of G9SX-LM@ should be considered.
Input frequency range: 1000 max.
Set the number of cogwheel teeth such that the value of the number of rotations at normal operation
(high speed) x 1 / 60 x value of the number of cogwheel teeth becomes 1000 max.
Low speed detection settings: 2 to
10 Hz
Set the number of cogwheel teeth such that the value of the number of rotations at low speed x 1 / 60 x
value of the number of cogwheel teeth becomes within the range of 2 to 10.
According to the information above, when setting the number of cogwheel teeth at "6," the values will be as mentioned below. These values are
frequencies input to rotation detection input of G9SX-LM@, falling within the ranges of "Input frequency range" and "Low speed detection settings".
At normal operation (high speed): 3000 rpm x 1 / 60 x 6 = 300 Hz
At low speed: 60 rpm x 1 / 60 x 6 = 6 Hz
Note: When the number of rotations between cogwheel and motor differs due to gear attachment, etc., take its rotation ratio into account.
Step 2: Selecting proximity sensors
Select proximity sensors according to the frequencies obtained in Step 1.
Since the input frequency to G9SX-LM@ at normal operation (high speed) is 300 Hz, select proximity sensors with higher response frequency
performance than this value. E2E-X2F1@ (M12 shielded type, Response frequency: 1.5 kHz) is used in this example.
Step 3: Determining the arrangement of proximity sensors for cogwheel
In this example, proximity sensors are installed in the horizontal direction to the cogwheel surface.
Step 4: Determining the distance between cogwheel and proximity sensors
Determine the distance between cogwheel and proximity sensors, and the height of the cogwheel teeth according to "2. Relationship between the
cogwheel shape and the setting of proximity sensors".
a. Distance of convexity: Design it to be 1.6 mm or less according to the table. In this example, a distance is set to 1 mm (50% of operating range).
b. Distance of concavity: Design it to be 8 mm or more according to the table. In this example, the height of the cogwheel is set to 20 mm, making
it 21 mm by adding 1 according to "1. Distance of convexity".
Step 5: Determining the widths of convexity and concavity
a. Because the number of cogwheel teeth obtained from Step 1 is 6, the angle of the combination of convexity and concavity is: 360°/ number of
cogwheel teeth: 6 = 60°.
According to the table of "2. Relationship between the cogwheel shape and the setting of proximity sensors", design the width of convexity as
twice as the width of concavity.
Therefore, ratio of an angle of convexity and angle of concavity is set to 2:1 = 40° : 20°.
b. Determine the diameter when concavity is assumed to be a circle.
In this example, set the diameter to 160 mm and verify if it satisfy the provisions of the table in "2. Relationship between the cogwheel shape
and the setting of proximity sensors".
According to a. in Step 5, the concavity width is 160 mm x π x 20° / 360° l 27.9 mm, satisfying the concavity width of E2E-X2F1@: 24 mm or
more.
c. Since the height of the cogwheel teeth is set to 20 mm according to Step 4, the diameter of the cogwheel at convexity is to be 160 mm + 20
mm x 2 = 200 mm. Verify that it satisfies the provisions of the table in "2. Relationship between the cogwheel shape and the setting of proximity
sensors".
According to a. in Step 5, the convexity width is 200 mm x π x 40° / 360° l 69.8 mm, satisfying twice or more of the concavity width obtained in
b. in Step 5.
Step 6: Determining the thickness of the cogwheel teeth
Determine the thickness according to the shape of the selected proximity sensors. Since the size of E2E-X2F1@ is M12, the thickness of the
cogwheel teeth should be 15 mm (standard object width of E2E-X2F1@) to install proximity sensors in the horizontal direction according to Step 3.
14
G9SX-LM
According to the process above, an example of shape of cogwheel and arrangement of proximity sensors are shown in the diagram below.
Proximity sensors are arranged to be intersecting each other. Note that the distance between proximity sensors defined in the table of "2.

4. Example of low speed detection settings
When the number of rotations at low speed is 50 rpm and the number of cogwheel teeth detected by proximity sensors is 6, the frequency at low
speed is 50 rpm x 1 / 60 x 6 = 5 Hz.
Consider the low-speed detection frequency accuracy (tolerance of -10%) such that low speed detection frequency setting is 6.0 Hz or higher.

Application Overview
1. Normal operating mode (safety input enabled)
• When normal operating mode (M1 = ON, M2 = OFF) is selected on the selector switch S6, the motor M rotates according to the operation command of the motor controller while the guard is closed.
• When the motor stopping command is input to the motor controller, the motor M starts stopping the rotation. When the pulse signal from the
proximity sensor that detects rotation is 2 Hz or less, the safety speed detecting output (ES1) turns ON, enabling the lock release. When the
lock release switch S4 is pressed, the guard lock is released and the guard is opened.
• Opening of the guard is detected by S1 and S2, and the power supply to the motor M is turned OFF immediately.
• The power supply to the motor M is kept OFF until the guard is closed and the reset switch S3 is pressed.
2. Maintenance mode (enabling input enabled)
• Lock release is enabled when maintenance mode (M1 = OFF, M2 = ON) is selected by the selector switch S6 and safety speed detection output
(ES1) is ON. When the lock release switch S4 is pressed, the guard lock is released and the guard is opened.
• The power supply to the motor M is turned ON when the enabling switch S5 is gripped to the middle position and the reset switch S3 is pressed.
• If the enabling switch S5 is released or gripped past the middle position, or if the pulse signal from the proximity sensor exceeds the low speed
detection frequency set value, the power supply to the motor M is turned OFF immediately.
• The power supply to the motor M2 is kept OFF until the enabling switch is gripped again to the middle position and the pulse signal from the
proximity sensor reaches the low speed detection frequency set value or less and the reset switch S3 is pressed.

Precautions for Safe Use
1. Use G9SX-LM@ 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-LM@ before
commissioning the system in which G9SX-LM@ is incorporated.
3. Do not apply DC voltages exceeding the rated voltages, or any AC
voltages to the G9SX-LM@ power supply input. Do not connect to
DC distribution network.
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-LM@ inputs.
Applying inappropriate voltages cause G9SX-LM@ to fail to
perform its specified function, which leads to the loss of safety
functions or damages to G9SX-LM@.
6. Be sure to correctly connect safety input devices to safety input
and enabling input to ensure proper operation of the safety
function.
7. The auxiliary error output, auxiliary monitoring output are NOT
safety outputs.
Do not use auxiliary outputs as any safety output. Such incorrect
use causes loss of safety function of G9SX-LM@ and its relevant
system. Also Logical connection outputs can be used only for
logical connections between G9SXs.
8. After installation of G9SX-LM@, 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.
9. A person in charge, who is familiar to the machine in which G9SXLM@ is to be installed, should conduct and verify the installation.
10.Mode selector switch should be operated only by qualified
personnel who is familiar to the machine. For example to avoid
unauthorized personnel's unexpected operation of mode selector
switch, use a selector switch with locking-key. The machine should
be stopped before the Mode selector inputs are switched.
11.Perform daily and 6-month inspections for the G9SX-LM@.
Otherwise, the system may fail to work properly, resulting in
serious injury.
12.Do not dismantle, repair, or modify G9SX-LM@. It may lead to loss
of its safety functions.
13.Conformity to IEC 61508 SIL3, IEC/EN 62061 SIL3 and
EN ISO13849-1 PLd was assessed with G9SX-LM@ alone. And
conformity to EN ISO13849-1 Safety Category 3 was assessed
with G9SX-LM@ set up with specified proximity sensors. 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.
14.OMRON shall not be responsible for conformity with any safety
standards regarding to customer's entire system.
15.Disconnect G9SX-LM@ from power supply when wiring. Devices
connected to G9SX-LM@ may operate unexpectedly.
16.Be cautious not to have your fingers caught when attaching
terminal sockets to the plugs on G9SX-LM@.
17.Do not use in combustible gases or explosive gases.

the G9SX-LM@ may malfunction or generate heat.
c. Logical AND Connection
Use VCTF cable or shielded cable for Logical AND connection
between units.
6. When connecting Expansion Units (G9SX-EX@-@) to G9SXLM224-F10-@:
1) Follow the procedure below:
a. Remove the termination connector from the receptacle on
G9SX-LM224-F10-@.
b. Insert the head of the connecting cable of Expansion Unit to
the receptacle on the G9SX-LM224-F10-@.
c. Set the termination connector to the receptacle on the
Expansion Unit at the end position. When G9SX-LM224-F10@ is used without expansion units, leave the termination
connector set on the G9SX-LM224-F10-@.
2) Do not remove the termination connector while the system is
operating.
3) Before applying supply voltage, confirm that the connecting
sockets and plugs are locked firmly.
4) All of the Expansion Units should be supplied with its specified
voltages within 10s after the connected G9SX-LM224-F10-@ is
supplied with voltage. Otherwise,G9SX-LM224-F10-@ detects
the power-supply error for the Expansion Units.Follow the procedure below:
7. Use 1NO1NC contact switch as a mode selector switch.
8. Use cables with length less than 100m to connect to Safety inputs,
Enabling inputs, Mode selector inputs, Feed-back/Reset inputs, or
between Logical AND connection inputs and Logical connection
outputs, respectively.
9. Use cables with length less than 100m to connect to proximity
sensor.
10.Set the time duration of low-speed detection frequency to an
appropriate value that does not cause the loss of safety function of
system.
11.Use specified cogwheels to firmly fix proximity sensors so as to
prevent the sensors from dropping off.
(Refer to page 13 "Shape of Cogwheel and Setting for Proximity
Sensors".
G9SX-LM
12.Logical connection between Units:
a. When using Logical AND connection inputs, set the Logical
connection preset switch to 'AND' position for the units which
the logical connection signal are input to.
b. Connect Logical connection outputs appropriately to Logical
AND connection inputs of the relevant unit. Verify the operation
of G9SX-LM@ before commissioning the system.
c. When configuring the safety related system, be sure to consider
that the delay of response time caused by logical connections
do not degrade the safety function of the system.
13.To determine safety distance to hazards, take into account the
delay of Safety outputs caused by the following time:
a. Response time of Safety inputs
b. Response time of Logical AND connection input
(See also "Characteristics" on page 3.)
14.Start entire system after more than 5s have passed since applying
supply voltage to all G9SXs in the system.
15.G9SX-LM@ may malfunction due to electro-magnetic
disturbances. Be sure to connect the terminal A2 to ground. When
using a DC power supply with light curtains, use DC power supply
which has no interruption by a power failure of 20ms.
Connect surge suppressors to both ends of coils of an inductive
load to suppress noise.
16.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.
17.Devices connected to G9SX-LM@ may operate unexpectedly.
When replacing G9SX-LM@, disconnect it from power supply.
18.Adhesion of solvent such as alcohol, thinner, trichloroethane or
gasoline on the product should be avoided. Such solvents make
the marking on G9SX-LM@ illegible and cause deterioration of
parts.
19.Do not use a CR type of surge suppressor for the inductive load
connected to an instantaneous safety output. This may cause
failure or malfunction. It is recommended to use a diode+Zenerdiode type of surge suppressor for an application for which a
response time needs to be allowed.
20.When reversing the rotation direction of the hazard source during
low-speed operation, allow the hazard source to stop for 500ms or
longer before changing the rotation direction. Reversing the
rotation direction without providing for stoppage time may result in
the safety outputs of G9SX-LM@ being turned OFF.
21.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.
22.Operate the reset input more than 0.4 seconds immediately after
the safety outputs are OFF. G9SX-LM@ 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.
Safety Category (EN ISO13849-1)
Standards Certification
G9SX-LM@ can be applied to the environment of PLd/Safety Category
3 required by EN ISO13849-1.
However, please note that this does not mean that G9SX can be
always used for this category under all similar conditions or situations.
Be sure to assess the entire system for conformity to a required
category before use.
G9SX-LM224-F10-@
For conformity to Safety Category 3 (EN ISO13849-1), please
check the following points;

inputs (D11-D12, D21-D22).
b. Use direct opening action switches for safety inputs (T61-T62,
T71-T72). When limit switches are used, at least one of them
should be a direct opening action limit switch. When connecting a
Safety Sensor to the G9SX-LM@, use a TYPE3 or 4 Safety
Sensor.
c. Use an enabling device, such as grip-switch, for Enabling inputs
(T11-T12, T21-T22)
d. Connect specified Proximity sensors to Rotation detection inputs
(D11-D12, D21-D22)
e. Apply input signals to T31-T32 for manual reset, or T31-T33 for
