In combination with a separating safety guard and the machine control, this safety component prevents dangerous machine movements from occurring while the safety guard is open. A stop command is triggered if the safety guard is opened during the dangerous machine function.

Before safety switches are used, a risk assessment must be performed on the machine, e.g., in accordance with:

EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.

General principles for design

EN ISO 12100, Safety of machinery – General principles for design – Risk assessment and risk reduction

IEC 62061, Safety of machinery. Functional safety of safety-related electrical, electronic and programmable electronic control systems.

Correct use includes compliance with the relevant requirements for installation and operation, for example

EN ISO 13849-1, Safety of machinery. Safety related parts of control systems.

General principles for design

EN 1088, Safety of machinery. Interlocking devices associated with guards.

Principles for design and selection

EN 60204-1, Safety of machinery. Electrical equipment of machines. General requirements

EN 60947-5-3, Specification for low-voltage switchgear and controlgear. Control circuit devices and switching elements. Requirements for proximity devices with defined behavior under fault conditions

The safety switch must be used only in conjunction with the designated CES actuators from EUCHNER. On the use of different actuators, EUCHNER provides no warranty for safe function.

Several devices are only allowed to be connected in series using devices intended for series connection with the CES-AR. Check the operating instructions for the related device. A combination of other CES devices or devices from other manufacturers is not allowed.

A maximum of 20 safety switches are allowed to be operated in a switch chain.

The user is responsible for the integration of the device into a safe overall system. For this purpose, the overall system must be validated, e.g. in accordance with EN ISO 13849-2.

Correct use requires observing the permissible operating parameters (see

Technical data).

If a product data sheet is included with the product, the information on the data sheet applies in case of discrepancies with the operating instructions.

In the estimation of the PL for the overall system, a maximum value of

100 years can be assumed for the MTTF d

according to the limit value in

EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value for the PFH d

of 2.47x10

/h.

When up to 11 devices are connected in series, these limit values can be assumed for the entire switch chain as a subsystem. As a subsystem, this switch chain achieves PL e.

Operating Instructions Safety Switch CES-AR-C01-CH-SA

Important!

In the case of series connection of more than 11 devices, the PFH d

can be calculated according to one of the stated methods in EN ISO 13849-1:2008, section 4.5.1.

If the simplified method according to section 6.3 of EN ISO 13849:2008-12 is used for validation, the Performance Level (PL) might be reduced when more than 11 devices are connected in series.

Exclusion of liability and warranty

In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed, or if any servicing is not performed as required, liability will be excluded and the warranty void.

General safety instructions

As the unique actuator codes are not evaluated, the CES-AR-C01-CH-SA version can only be used for applications in which a hazard cannot result from possible tampering with the system.

Safety switches fulfill personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.

Check the safe function of the safety guard particularly

Ì after any setup work

Ì after the replacement of a CES component

Ì after an extended period without use

Ì after every fault

Independent of these checks, the safe function of the safety guard should be checked at suitable intervals as part of the maintenance schedule.

Warning!

Danger of fatal injury in the event of incorrect connection or incorrect use.

Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective.

On this topic pay attention in particular to the measures for reducing the possibility of bypassing from EN 1088:1995+A2:2008, section 5.7.

The device is only allowed to be installed and placed in operation by authorized personnel

Ì who are familiar with the correct handling of safety components

Ì who are familiar with the applicable EMC regulations

Ì who are familiar with the applicable regulations on health and safety and accident prevention

Ì who have read and understood the operating instructions.

Caution!

Risk of damage to equipment as a result of incorrect installation. Safety switches must not be used as a mechanical end stop.

Fit an additional end stop for the movable part of the safety guard.

Important!

Prior to use, read the operating instructions and keep these in a safe place.

Ensure that the operating instructions are always available during mounting, setup and servicing work. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage period required. For this reason you should archive a printed copy of the operating instructions. You can download the operating instructions from www.EUCHNER.de.

Operating Instructions Safety Switch CES-AR-C01-CH-SA

Function

The device complies with the following safety requirements:

Category 4, PLe according to EN ISO 13849-1

Redundant design of the circuit in the unit with self-monitoring

This means that the safety system still functions even if an internal component fails

The switch state of the semiconductor outputs is continuously monitored internally

Short circuit detection at the safety outputs by pulse signals

The following switch-on condition applies to safety outputs OA and OB (see also

System status table and the section Typical system times):

Safety guard closed

Both safety outputs (IA and IB) must be on

The system consists of the following components: coded actuator (transponder) and switch.

Every EUCHNER actuator supplied has an electronic coding (unique coding) that is read by the read head. Only if a correct coding is detected does the system accept the actuator. The code in an actuator cannot be reprogrammed.

Unlike systems with unique code detection, on the CES-AR-C01-CH-SA a specific code is not polled but instead it is only checked whether the actuator is of a type that can be detected by the system (multicode detection). There is no exact comparison of the actuator code with the code defined in the safety switch (unique code detection).

The safety switch is fastened to the fixed part of the safety guard.

The actuator attached to the movable part of the safety guard is moved towards the read head fitted in the safety switch by closing the door. When the switch-on distance is reached, power is supplied to the actuator by the read head by induction and data can be transferred.

If a permissible code is detected, the safety outputs are released.

Due to the combination of dynamic polling of the actuator and the redundant, diverse design of the safety electronics with the two feedback safety outputs, the safety switch will enter the safe state with every detectable fault.

When the safety guard is opened, the safety outputs switch off the safety circuit and the monitoring output (OUT) is switched off. The state of the safety outputs is monitored internally by two microprocessors.

If faults are detected, the safety circuit is switched off and the DIA LED illuminates.

In case of devices with a DIA monitoring output, the output is switched on.

The safety switch has a redundant circuit design with self-monitoring. This means that the safety system is still effective even if a component fails.

The system is designed so that failures will not result in the loss of the safety function. The occurrence of failures is detected by cyclic self-monitoring at the latest on the next demand to close the safety contacts (e.g. on starting).

If the safety door with the actuator should settle over time, the actuator can drift out of the read head operating distance. The device recognizes this and indicates that the actuator is in the limit range (function available for V 1.1.2 and higher).

This allows the safety door to be readjusted in time.

Operating Instructions Safety Switch CES-AR-C01-CH-SA

Changing the approach direction

Caution!

Risk of damage to equipment as a result of trapped cables.

Make sure that the cables are not trapped or torn off when the approach direction is changed.

The active face of the read head can be adjusted in 5 directions. It is marked by the red face.

The plug connector can be realigned in 45° steps to change the direction of the cable outlet (when using elbow connectors).

1. Remove the top part of the mounting base and push the bottom part of the mounting base off the read head.

2. Unscrew the screws on the fastening bracket.

3. Undo the read head from the fastening bracket and tilt the read head forward by 90°.

The active face is now pointing downward.

4. Hold the fastening bracket tight and turn the read head by 180°.

5. Re-tighten the screws for the read head on the fastening bracket. Tightening torque 0.6 Nm.

6. Turn the read head in 90° steps until the desired approach direction is reached.

Change the alignment of the plug connector if necessary.

7. Push the read head onto the bottom part of the mounting base and reassemble the mounting base.

Electrical connection

The following connection options are available:

Separate operation

Series connection with Y-distributors from EUCHNER (only with M12 plug connector)

Series connection, e.g. with wiring in the control cabinet.

Operation on an AR evaluation unit

Warning!

In the event of a fault: Loss of the safety function due to incorrect connection.

To ensure safety, both safety outputs (OA and OB) must always be evaluated.

The monitoring output OUT or DIA must not be used as a safety output.

Lay the connection cables with protection to prevent the risk of short circuits.

Caution!

Risk of damage to equipment or malfunctions as a result of incorrect connection.

Do not use a control system with pulsing or switch off the pulsing function in your control system. The device generates its own clock signal on the output lines OA/OB. A downstream control system must tolerate these pulses, which may have a length of up to 1 ms.

The pulses are also output when the safety outputs are switched off.

Depending on the inertia of the connected device (control system, relay, etc.), this can lead to short switching processes.

The inputs on an evaluation unit connected must be positive-switching, as the two outputs on the safety switch deliver a level of +24 V in the switched-on state.

All the electrical connections must either be isolated from the mains supply by a safety transformer according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures (PELV).

For use and operation as per the requirements, a power supply with the feature "for use in class 2 circuits" must be used. The same requirement applies to the safety outputs.

Alternative solutions must comply with the following requirements: a) Electrically isolated power supply unit with a max. open-circuit voltage of 30

V/DC and a limited current of max. 8 A.

b) Electrically isolated power supply unit in combination with fuse as per UL248.

This fuse should be designed for max. 3.3 A and should be integrated into the 30 V/DC voltage section.

For use and applications as per the requirements of , a connection cable listed under the UL category code CYJV2 or CYJV must be used. The connection cables from EUCHNER meet these requirements. The same requirement applies to the safety outputs.

All electrical outputs must have an adequate protective circuit for inductive loads. The outputs must be protected with a free-wheeling diode for this purpose. RC interference suppression units must not be used.

Power devices which are a powerful source of interference must be installed in a separate location away from the input and output circuits for signal processing. The cable routing for safety circuits should be as far away as possible from the cables of the power circuits.

Operating Instructions Safety Switch CES-AR-C01-CH-SA

Caution!

Important!

In order to avoid EMC interference, the physical environmental and operating conditions at the installation site of the device must comply with the requirements according to the standard EN 60204-1:2006, section 4.4.2 (EMC).

Please pay attention to any interference fields in case of devices such as frequency converters or induction heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.

If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not flash), the safety switch must be returned unopened to the manufacturer.

Safety in case of faults

The operating voltage U

is reverse polarity protected.

The contacts OA/OB are short circuit proof.

A short circuit between OA and OB is detected by the switch.

A short circuit in the cable can be excluded by laying the cable with protection.

Figure 1: Circuit example with six CES-AR

A safety relay is connected downstream which consumes 75 mA at each of the two safety inputs. This operates over the whole temperature range with a voltage of 19.2 V (corresponds to 24 V -20%).

All the relevant values can now be determined using the example table:

1. Select the corresponding section in the column n (max. number of switches).

Here: 6 switches.

2. In column I out

(possible output current per channel OA/OB), find a current greater than or equal to 75 mA. Here: 100 mA.

It is then possible to determine the maximum cable length from the last switch

(#6) to the control system from column l

. Here: a length of 50 m is permitted.

Result: The desired cable length l table. The overall length of the switch chain l value of 200 m.

of 40 m is below the permitted value from the max

of 140 m is less than the maximum

The planned application is therefore functional in this form.

If a single CES-AR-C is used, connect the switch as shown in Figure 3. The OUT output can also be connected here to a control system as a monitoring output.

The switch can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 seconds. The RST input must be connected to 0 V if it is not used.

The subsystem CES-AR complies with PL e in accordance with EN 13849-1. To integrate the subsystem in a category 3 or 4 structure, it is necessary to monitor the downstream load (the feedback loop must be monitored).

Connection of several CES-AR-C in a switch chain

An AR switch chain may contain a maximum of 20 safety switches.

In the estimation of the PL for the overall system, a maximum value of

100 years can be assumed for the MTTF d

according to the limit value in

EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value for the PFH d

of 2.47x10

-8

/h.

When up to 11 devices are connected in series, these limit values can be

Ì assumed for the entire switch chain as a subsystem. As a subsystem, this switch chain achieves PL e.

In the case of series connection of more than 11 devices, the PFH d

can be calculated according to one of the stated methods in EN ISO 13849-1:2008, section 4.5.1.

If the simplified method according to section 6.3 of EN ISO 13849:2008-12 is used for validation, the Performance Level (PL) might be reduced when more than 11 devices are connected in series.

The series connection is shown here based on the example of the version with plug connectors M12. The switches are connected one behind the other with the aid of pre-assembled connection cables and Y-distributors. If a safety door is opened or if a fault occurs on one of the switches, the system shuts down the machine. A higher level control system cannot, however, detect which safety door is open or on which switch a fault has occurred with this connection technology. A special AR evaluation unit is required for this purpose (see section Information on operation

on an AR evaluation unit).

The series connection can also be realized via additional terminals in a control cabinet.

The safety outputs are permanently assigned to the respective safety inputs of the downstream switch. OA must be connected to IA and OB to IB. If the connections are interchanged (e.g. OA to IB), the unit will switch to fault state).

Always use input RST in series connections. All switches in a chain can be reset at the same time with this reset input. To do this, a voltage of 24 V must be applied to the RST input for at least 3 seconds. If input RST is not used in your application, it should be connected to 0 V.

Note the following on this aspect:

A common signal must be used for all switches in the chain. This can be a changeover switch or the output of a control system. A button is not suitable because Reset must always be connected to GND during operation (see switch

S1 in Figure 5).

Reset must always be performed simultaneously for all switches of the chain.

Information on operation on an AR evaluation unit

Devices with version number V 1.1.2 or higher can be operated on an AR evaluation unit. Please refer to the operating instructions for the relevant AR evaluation unit for more information.

Notes on operation with safe control systems

Please observe the following requirements for connection to safe control systems:

Use a common power supply for the control system and the connected safety switches.

A clocked power supply must not be used for UB. Tap the supply voltage directly from the power supply unit. If the supply voltage is connected to a terminal of a safe control system, this output must provide sufficient electrical current.

Always connect inputs IA and IB directly to a power supply unit or to outputs

OA and OB of another EUCHNER AR device (series connection). Clocked signals must not be present at inputs IA and IB.

Outputs OA and OB can be connected to the safe inputs of a control system.

Prerequisite: The input must be suitable for clocked safety signals (OSSD signals, e.g. from light curtains). The control system must tolerate clock pulses on the input signals. This normally can be set up by parameter assignment in the control system. Observe the notes of the control system manufacturer. For

the pulse duration of your safety switch, please refer to the section Typical

system times on page 23.

Typical system times

The specified times are maximum values for AR switch chains with 20 devices.

Individual devices have shorter system times.

Ready delay: After switching on, the unit carries out a self-test for 8 s. The system is ready for operation only after this time.

Switch-on time of safety outputs: The max. reaction time from the moment when the actuator is at the operating distance (safety door closed) to the moment when the safety outputs switch on T on

is 400 ms.

Simultaneity monitoring, safety inputs IA/IB: If the safety inputs have different switching states for longer than 150 ms, the safety outputs OA/OB will be switched off.

Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs OA and OB are deactivated after a maximum of 360 ms.

Difference time: The safety outputs OA and OB switch with a slight time offset.

They have the same signal state at the latest after a difference time of 10 ms.

Clock pulses at the safety outputs: The device generates its own clock signal on the output lines OA/OB. A downstream control system must tolerate these pulses, which may have a length of up to 1 ms.

This can usually be set up in the control systems by parameter assignment. If parameter assignment is not possible for your control system or if shorter clock pulses are required, please contact our support organization.

The pulses are also output when the safety outputs are switched off.
