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.. 500 µs max. 6 G9SX-LM Operation Functions Operation Mode Low-speed Detection Function The relationship between safety inputs/ enabling inputs and safety instantaneous outputs of the G9SX-LM@ differs depending on the status of the selector switch as shown below. 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. Selector switch = Normal operating mode (M1 = ON, M2 = OFF) Enabling input Safety input - - ON OFF - - ON OFF Rotation detection input (low speed detection frequency) (Hz) F Safety instantaneous outputs F-10 % (Time) Selector switch = Maintenance mode (M1 = OFF, M2 = ON) Enabling input Safety input Rotation detection input (low speed detection frequency) ON ON OFF OFF - - - - Equal to or less than the preset value Equal to or more than the preset value Equal to or less than the preset value Equal to or more than the preset value Safety instantaneous ON OFF OFF OFF outputs Note: 1. For Maintenance mode, the low-speed detection frequency must be the preset value or less. If the frequency input exceeds the preset value, the safety instantaneous outputs are turned OFF. 2. When the logical AND connection preset switch is set to AND (enabled), the logical AND connection input must be ON to set Safety instantaneous outputs in the ON state. 3. For reset mode, take the operation of the application into account to select auto reset or manual reset.

For design of cogwheel and installation of proximity sensors, see page 12 "Shape of Cogwheel and Setting of Proximity Sensors". S2 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". a Unit B a 2.

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: Cross fault detection Safety Category (Safety input) a.The safety instantaneous outputs, safety speed detection outputs, and logical AND connection outputs lock out. 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 terminal to +24 V. If not connected, G9SX-LM@ will detect it as an error.

The response time of the entire system regarding speed detection can be calculated by the following formula: Ts = Tp + Tf + Tr + Tm Ts Tp Tf Tr Tm Unit A AND L1 A2 T41 T42 OFF AND OFF Unit B Note: 1. A setting error will occur and Unit B will lock out if the logical AND setting switch on the Unit is set to OFF. 2. Set the logical AND setting switch on Unit A to OFF or the output of Unit A will not turn ON. (4) Low-speed detection settings To set a threshold value of low-speed detection frequency, use lowspeed detection settings switches (one each on the front and back of the Unit). The Unit operates normally only when the preset values on both switches agree.

In that case, it is not abnormal though the operation indicator of the proximity sensor blinks. • When the rotation of the cogwheel is stopping, and both proximity sensors are turning ON. 12 G9SX-LM 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 Proximity sensor B 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. 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 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.

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. Relationship between the cogwheel shape and the setting of proximity sensors" must be satisfied. M12 15.00 Proximity sensor A 20.0° 1.00 φ200.00 φ160.00 20.0° 40.0° 21.00 Proximity sensor B 10.0° (27.9) (69.8) The diagram below shows a design when proximity sensors are installed in the vertical direction to the cogwheel surface. Proximity sensor A 20.0° 20.0° M12 φ200.00 φ160.00 φ180.00 40.0° Proximity sensor B 1.00 10.0° (69.8) (27.9) When installing proximity sensors in the vertical direction to the cogwheel surface, note that the height of cogwheel teeth should not be affected by surrounding metal products. For details in influence of surrounding metal, see the E2E Catalog. 15 G9SX-LM 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.

Do not connect an emergency stop switch to G9SXEmergency Stop Switches LM@. Other devices Evaluate whether devices used are appropriate to satisfy the requirements of safety category level. G9SX-LM 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. 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/EN 61508 SIL3, IEC/EN62061 SIL3 and ISO13849-1 PLd was assessed with G9SX-LM@ alone. And conformity to EN954-1 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. 18.Proximity sensors to be used should be selected based on the max. number of revolutions during normal operation and the number of cogwheel teeth. Please refer to 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) 23 G9SX-LM Precautions for Correct Use 1.

Wiring a. G9SX-LM224-F10-@ • Use the following to wire to G9SX-LM@. Solid wire 0.2 to 2.5mm2 AWG24 to AWG12 Stranded wire (Flexible wire) 0.2 to 2.5mm2 AWG24 to AWG12 • Strip the cover of wire no longer than 7mm. b. G9SX-LM224-F10-RT (with screw terminals) Tighten each screw with a specified torque of 0.5 to 0.6N·m, or 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.
