## **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: 500 μs max.

## **Operation**
## **Functions**
## **Logical AND Connection**
## ● **Example with G9SX-AD322-** @
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”.

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).)

## ● **Example with G9SX-ADA222-** @
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”.

## **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.

## **3.Setting Logical AND Connection (Advanced Unit)**
When connecting two or more Advanced Units (or Basic Units) by logical AND connection, set the logical AND connection preset switch on the Advanced Unit that is on the input side (Advanced Unit G9SX-AD322 in the following diagram) to AND.
The default setting of the logical AND connection preset switch is set to OFF.

- **Note: 1.** A setting error will occur and Advanced Unit G9SX-AD322 will lock out if the logical AND setting switch on the Unit is set to OFF.
**2.** Set the logical AND setting switch on Advanced Unit A to OFF or an error will occur.

- **Note: 1.** When not connecting Advanced Unit B, leave terminals T41 and T42 of the G9SX-ADA222 Advanced Unit open, and set the logical AND setting switch T41/T42 to OFF.
**2.** When not connecting Advanced Unit C, leave terminals T51 and T52 of the G9SX-ADA222 Advanced Unit open, and set the logical AND setting switch T51/T52 to OFF.
The following table shows the relationship between the logical ON setting switches and the conditions for safety outputs turning ON.

## **4.Setting the OFF-delay Time (Advanced Unit)**
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.

**Safety Guard Switching Unit G9SX-GS**
## **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 max.

## **Operation**
## **Functions**
## **Auto Switching Function**
The following table shows the relationship between the safety inputs and safety outputs of the G9SX-GS @ when auto switching is selected.
|selected.|||||
|---|---|---|---|---|
|**Safety input A**|ON|ON|OFF|OFF|
|**Safety input B**|ON|OFF|ON|OFF|
|**Safety output**|ON|ON|ON|OFF|
- **Note: 1.** If the logical AND connection input is enabled, it must be ON as a necessary condition for the above table.
**2.** Select either auto reset or manual reset for the reset mode, depending on the operation of the application.
## **Manual Switching Function**
As shown in the following table, the relationship between the safety inputs and safety outputs of the G9SX-GS @ depends on the setting of the connected mode selector when manual switching is selected.
## **Mode Selector = Normal Operating Mode (M1 = ON, M2 = OFF)**
|**Safety input A**|ON|ON|OFF|OFF|
|---|---|---|---|---|
|**Safety input B**|ON|OFF|ON|OFF|
|**Safety output**|ON|OFF|ON|OFF|
|**Mode Selector = Maintenance Mode (M1 = OFF, M2 = ON)**|||||
|**Safety input A**|ON|ON|OFF|OFF|
|**Safety input B**|ON|OFF|ON|OFF|
|**Safety output**|ON|ON|OFF|OFF|
- **Note: 1.** If the logical AND connection input is enabled, it must be ON as a necessary condition for the above table.
**2.** Select either auto reset or manual reset for the reset mode, depending on the operation of the application.
## **Logical AND Connection**
The 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 AND between safety signal “a” and safety signal “b.” In the example shown below, the logical AND connection results in a safety output of “a AND b” for Unit B.

## **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.

Serious injury may possibly occur due to breakdown of safety outputs.
**==> picture [32 x 32] intentionally omitted <==**
Do not connect loads beyond the rated value to the safety outputs.
Serious injury may possibly occur due to loss of required safety functions.
Wire the G9SX properly so that the safety outputs do not short-circuit with the Unit power supply or load power supply.
Serious injury may possibly occur due to malfunction of safety outputs.
Add a circuit to protect against back electromotive force when connecting inductive loads to safety outputs.
Serious injury may possibly occur due to loss of safety functions. Use appropriate devices as given in the following table.
|**Control Devices**|**Requirements**|
|---|---|
|Door interlocking switches<br>or Safety limit switches|Use approved devices with Direct<br>Opening Mechanism complying with<br>IEC/EN 60947-5-1 and capable of<br>switchingmicro loads of 24 VDC, 5 mA.|
|Safety sensors|Use approved devices complying with the<br>relevant product standards, regulations<br>and rules in the country where it is used.<br>Consult a certification body to assess<br>that the entire system satisfies the<br>required safetycategorylevel.|
|Relays with forcibly guided<br>contacts|Use approved devices with forcibly<br>guided contacts complying with EN<br>50205. For feedback purpose use<br>devices with contacts capable of<br>switchingmicro loads of 24 VDC, 5 mA.|

## **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.
**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.

1. At least 25 mm beside side faces of the G9SX.
2. At least 50 mm above top face of G9SX and below bottom face of G9SX.
50 mm min.
**5.** Wiring
- (1) G9SX
- Wire the G9SX as described below.
|**Solid wire**<br>**Stranded wire**|0.2 to 2.5 mm2(AWG24 to AWG12)<br>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.

- (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.
**49**
**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.
