4-1 OSSD

An OSSD output is a safety output for the safety-related part of a machine control system. OSSD 1/2 is a pair of safety outputs that are redundant. The GS (Non-contact) generates self-diagnosis signals on its internal control circuit to perform diagnostics on the OSSD. These signals periodically force the OSSD into a temporary OFF-state when the OSSD is in the ON-state. If the internal control circuit receives a feed-back signal (OFF-signal) based on the self-diagnosis, the GS (Non-contact) determines that its OSSD is operating normally. If the OFF-signal is not returned to the internal control circuit, the GS (Non-contact) determines that there is a problem with the OSSD or wiring and goes to an error state.

 OSSD operation

The OSSDs go to OFF state:

• During startup, in the error state, when switching the coding level

When all the conditions shown below are met during normal operation, the OSSDs go to ON state. (*1)

• The sensor has detected an actuator.

• Safety inputs are ON.

*1: The OSSDs go to OFF state in the interlock reset ready state.

• For the wiring to a safety-related machine control system, the output of both OSSD 1 and OSSD 2 must be used by the safety-related machine control system in order to create a safety system.

• If only one OSSD output is used to construct the machine’s control system, an OSSD malfunction will make it impossible to stop the machine, which may lead to extremely dangerous situations including serious injury to or death of the machine’s user.

• When using a PNP sensor, do not cause a short-circuit between the OSSD and +24V. Otherwise, the OSSDs will stay in the ON-state and it will cause a dangerous situation.

• When using a PNP sensor, be sure to connect the load between the OSSD and 0 V. Connecting this between the OSSD and +24 V by mistake will invert the OSSD operation from its normal behavior, which is extremely dangerous.

• When using an NPN sensor, do not cause a short-circuit between the OSSDs and 0V. Otherwise, the OSSDs stay in the ON-state and it will cause a dangerous situation.

• When using an NPN sensor, be sure to connect the load between the OSSD and +24 V. Connecting this between the OSSD and 0 V by mistake will invert the OSSD operation from its normal behavior, which is extremely dangerous.

• To prevent malfunctions caused by ground faults on the OSSD output wire, perform wiring in a manner such that the requirements specified in paragraph 9.4.3 of IEC 60204-1 are met.

Advanced function type

This function controls the OSSDs of the GS (Non-contact) with input signals from sensors or similar devices connected to the safety inputs. Safety input 1 and safety input 2 form a safety input pair. If safety input 1 or safety input 2 turns OFF, the OSSDs turn OFF. Multiple GS units can be connected and used in an expanded system (with a cascade connection) by connecting the OSSDs of a different GS (Noncontact) or GS (Lock) to the safety inputs. The system can be expanded to include up to thirty units in the case of the GS (Non-contact).

The simple function type has no safety input.

• Wire the safety inputs as shown below when they are not in use. PNP type: Short circuit to 24 V. NPN type: Short circuit to 0 V.

• If safety input 1 and safety input 2 are mismatched for 3 seconds or more a Safety Input Error will occur.

 Emergency stop switch/button wiring

Wiring an emergency stop switch/button to the safety inputs makes it possible to perform an emergency stop on the machine by pressing the emergency stop switch/button.

• Use an emergency stop switch/button that has two or more

independent, NC (normally closed) contacts. For the requirements related to emergency stop switches, see IEC 60204-1, ISO 13850, and all other requirements, regulations, standards, and laws related to occupational safety and health in the country or area where the GS (Non-contact) will be used. For such regulations, you should directly contact the regulatory agency responsible for occupational safety and health in your country or region.

• Ensure that the device does not start or restart automatically

when the emergency stop switch/button is reset.

• Only the devices shown below can be connected to the

safety inputs. Do not connect any other devices.

• GS (Non-contact) OSSDs, GS (Non-contact) OSSDs, and emergency stop switch/button

• When using a PNP sensor, please connect the OSSDs of the PNP type GS (Lock) or GS (Non-contact) to the safety inputs.

• When using a NPN sensor, plesae connect the OSSDs of the NPN type GS (Lock) or GS (Non-contact) to the safety inputs.

4-3 Interlock Function

Interlock is a function that prevents the OSSDs from automatically going into the ON-state from the OFF-state. This prevents the unintended start-up and/or the unintended restart of the machine if the interlock is applied to the GS (Non-contact). It is necessary to perform the reset operation in order for the GS (Non-contact) to go back to normal operation from the interlock condition.

• Be sure to absolutely confirm that there is nobody in the hazardous zone before the interlock condition is terminated (i.e. the machine system restarts) by the interlock reset mechanism.

• Install the switch, etc. for releasing the interlock state in a position where it is possible to check the entirety of the hazardous zone and where the switch, etc. cannot be operated from within the hazardous zone.

• When the interlock function is set to Automatic, it is necessary to ensure the safety of the entire control system in order to prevent unexpected starts from occurring.

• Exercise caution to prevent the reset/EDM input from forming a short circuit with other inputs or outputs.

4-4 EDM Function

The GS (Non-contact) can monitor the state of external devices, such as a safety relay or contactors that are connected to the OSSDs, in order to detect the failure of the external device. This monitoring function is called the EDM function.

 EDM function settings

Use the wiring to configure the settings. The wiring varies depending on whether the interlock function is used. For details, see “4-3 Interlock Function” (page 6).

4-5 AUX Output

This is an informational output used to check the operating status of the GS (Non-contact).

The AUX outputs cannot be used as the safety outputs to a safety-related control system.

4-6 Coding Level

The GS (Non-contact) has two coding levels.

Coding level: Low (multi operation)

Coding level: High (unique operation)

Any actuator is detected when it enters the range of the operating distance from the sensor. (Initial setting)

Only the specific actuator that the sensor has been taught to detect is detected when it enters the range of the operating distance from the sensor. The sensor does not respond if an actuator other than the actuator that it has been taught to detect is within the range of the operating distance.

The interlock function cannot be set on the simple function type and standard type. The interlock function is fixed to Automatic.

On the advanced function type, the interlock function setting can be selected from two types: Automatic and Manual.

Automatic and Manual indicate the following operations.

Automatic:

The OSSDs immediately switches to the ON state when the conditions for doing so—such as the door closed—are met.

Manual:

Even if the conditions for switching the OSSDs to the ON state are met, the OSSDs maintain the OFF state (interlock state).

To set the OSSDs to the ON state and to start the machine, close the door to which the GS (Non-contact) has been installed and perform the reset operation after the preparations for starting the machine are complete. This sets the OSSDs to the ON state and terminates the interlock state.

6-3 Troubleshooting

If the operation of the GS (Non-contact) is abnormal, identify the cause of the error and carry out the countermeasures according to the following tables.

 [A] The OSSD does not turn ON (or turns OFF unexpectedly).

Possible cause

The GS (Non-contact) is in the error state.

The actuator is not detect ed correctly.

The actuator is broken. Replace the actuator.

During operation with the “High” encoding level, an actuator different from the one that was taught was detected.

Safety input is not ON.

The unit is in the interlock reset ready state.

The sensor and actuator a re at a greater distance than the specified operating distance Sao (OFF→ON).

The unit is affected by the surrounding metal.

The unit is affected by interference from other sensors.

Confirmation

method

The highly visible indicator is blinking in red.

The highly visible indicator is ON in red.

The highly visible indicator is blinking in orange.

The INPUT READY indicator is blinking in yellow.

The INPUT READY indicator is ON in yellow.

— Check the installation.

Identify the cause of the error and implement countermeasures according to “Display details when an error occurs.”

Bring the actuator within the detection range.

Use the actuator that was taught to the unit.

Turn ON the safety input.

Release the interlock state by turning the RESET/EDM input ON.

Countermeasure

 [B] The OSSD does not turn OFF (or turns ON unexpectedly).

DANGER

Possible cause

The sensor and actuator are at a shorter distance than the specified operating distance Sar (ON→OFF).

The unit is affected by the surrounding metal.

The unit is affected by interference from other sensors.

The cascade connection wiring is incorrect.

Confirmation

method

— Check the installation.

The INPUT READY indicator is off.

Check the safety input wiring.

Countermeasure

 [C] The OSSD sometimes turns ON and OFF.

Possible cause

The sensor is subject to noise. —

The unit is affected by the surrounding metal.

The unit is affected by interference from other sensors.

The sensor and actuator are at a distance between the specified operating distance Sao (OFF→ON) and Sar (ON →OFF).

Confirmation

method

— Check the installation.

Check the noise environment around the wiring.

Countermeasure

 [D] The connected device repeatedly turns the OSSD ON/OFF

at high speed (chattering).

Possible cause

The OSSDs turn OFF periodically by the selfdiagnosis function, but the connected device may be recognizing this short OFF signal.

Confirmation

method

—

Countermeasure

Select a device that does not detect the OSSD’s periodic OFF signal for the connected device.

 [E] No indicators light.

Possible cause

The power is off or the power supply voltage is insufficient.

An extension cable or other such connector cable is not connected correctly.

Confirmation

method

Power supply voltage or power supply wiring

Connection status of connector cables

Countermeasure

Ensure that the power supply voltage is within the range in the specifications. Wire the power supply correctly.

If necessary, connect the parts again.

6-4 Inspection and Maintenance

Inspect the safety function of the GS (Non-contact) on the basis of the results of a risk assessment of the target machine. It is strongly recommended that, at minimum, the following items and periods be met.

• To prevent danger due to the machine starting, thoroughly ensure that no one is present in the hazardous zone during inspection.

• If some error is found on the GS (Non-contact) as a result of the inspection, do not operate the machine.

• Initial inspection

Items

 The sensor and actuator are installed on the basis of the installation

conditions, installation methods, and wiring specifications specified in this manual.

 The safety functions being used (“4-1 OSSD” (page 5), “4-2 Safety Input”

(page 6), “4-3 Interlock Function” (page 6), or “4-4 EDM Function” (page

6)) operate as intended.

• Periodic inspection

Periods

SIL3/PLe: Once/month or more, SIL2/PLd: Once/year or more (ISO 14119)

Items

 If an emergency stop switch is connected to the safety input, the safety

function acts correctly when the emergency stop switch is pressed.

 There are no changes in the mounting conditions of the sensor and

actuator or in the doors, etc. to which these devices are installed.

 The door, etc. is not deformed.  There are no changes to the installation status that will affect the results of

the risk assessment carried out at the start of the installation.

 The mounting screws and seals (in the case that seals have been applied

to the manual release) have been applied correctly.

 No excessive damage or dirt is present.

Especially in the following cases, check the same details as the initial inspection.

• When a change is made to the installation, wiring, or functions

• When the sensor or actuator is replaced

• When the equipment is not used for a long period of time

• When a defect occurs

Store the inspection results together with the machine’s records.

Errors found on the sensor or actuator cannot be repaired by the customer. Replace the product with a new one or contact the nearest KEYENCE office.
