Correct useThe Coded Electronic Safety systems CES are safety devices for monitoring mov-able safety guards so that:

Dangerous work on machines can only be carried out if the safety guards are closed.

A stop command is triggered if a safety guard is opened while the machine is running.

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

EN 13849-1, Safety of machinery. Safety related parts of control systems. General principles for design, Annex B

EN ISO 141�1, Safety of machinery. Principles for risk assessment

The following applies additionally for evaluation units, read heads and actuators of the type CES-...-EX and CEM-...-EX :

Safety precautionsThe safety system CES-AZ-AES-01B-EX complies with the following safety require-ments:

Proximity device with self-monitoring type PDF-M according to EN 60947-5-3.

Performance level e according to EN 13849-1: �007-07

In relation to the structural requirements, category 4 in accordance with EN 13849-1: �007-07, comparable to category 4 in accordance with EN 954-1, is achieved.

Redundant design of the circuit in the evaluation unit with self-monitoring. As a result, the safety system is still effective even if a component fails.

When the safety guard is opened and closed, it is checked whether the safety system relays open and close correctly.

Monitoring output O1 must not be used as a safety output.

Safety switches fulfill personal protection functions. Incorrect installation or tamper-ing can lead to severe injuries to personnel.

The number of teach-in and switching operations is saved in the internal memory in the evaluation unit. If necessary, this memory can be read by the manufacturer.

Check the safe function of the safety guard particularly

after any setup work

after the replacement of a CES component

after an extended period without use

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

The year of manufacture of the device can be derived from the serial number on the rating plate.

Important!

The evaluation unit must be replaced with a new device after 5 years of opera-tion.

Important!

Prior to use, read the operating instructions and the system manual of the CES components used, and keep these in a safe place. Ensure the operat-ing instructions and the system manual are always available during mounting, setup and servicing. 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 system manual. If you should lose the operating instructions or the system manual, you can download these documents from www.EUCHNER.de.

System descriptionThe CES non-contact safety system consists of three components:

Coded actuator

Read head

Evaluation unit

1 read head may be connected to the evaluation unit CES-AZ-AES-01B.

It is also possible to connect a start button (monitored start) and a feedback loop for monitoring external relays and contactors.

The individual configuration is defined by a setup procedure.

Each delivered actuator possesses a unique electronic coding and so is a unique element in the system used. The code in an actuator cannot be reprogrammed.

The read heads are fastened to the fixed part of the safety guard and are each connected to the evaluation unit via a two-core screened cable.

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

The bit pattern read is compared with the code saved in the evaluation unit. If the data match, the door monitoring output O1 (semiconductor output) on the read head is set HIGH and the safety outputs (relay outputs) are then enabled. The OUT LED illuminates.

Optionally, a feedback loop can be connected to the evaluation unit. Then the evalu-ation unit can only be started with the feedback loop closed. A welded contactor contact in the release path will thus be detected when a start request is made.

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

When a safety guard is opened, the safety outputs switch off the safety circuit and the OUT LED goes out. The state of the safety outputs is monitored internally by positively driven NC contacts (relay output).

Independent of the switching state of the safety circuit, the position of the safety door can be polled via the output O1.

If an internal fault occurs in the evaluation unit, the safety circuit is switched off, the diagnostic output (DIA) is set HIGH and the DIA LED illuminates red.

InstallationWarning!

Mounting must be performed only by authorized personnel.Carry out the work only if there is no ignitable atmosphere and the system is switched off.

Actuator and read head must be easily accessible for inspection and replace-ment.

The switching operation must only be triggered by the specific actuator desig-nated for this purpose.

Actuator and read head must be fitted so thatthe front faces are at the minimum switch-on distance 0.8 x Sao or closer (see technical data) with the safety guard closed.when the safety guard is opened to the assured switch-off distance Sar, a haz-ard is excluded. Note: From the assured switch-off distance Sar, the relay outputs are safely switched off.they are positively mounted on the safety guard, e.g. using the safety screws included (cube-shaped design) or adhesive (cylindrical design M1�).they are not used as a mechanical end stop. Note: Fit an additional end stop for the movable part of the safety guard.

Pay attention to the maximum tightening torque for the read head or safety switch and actuator mountings of 1 Nm.

If installed flush, the switching distance changes as a function of the installation depth and the safety guard material.

The evaluation unit must be mounted in a control cabinet with a minimum de-gree of protection of IP 54. A snap-in element on the rear of the device is used for fastening to standard rails.

If several evaluation units are mounted side by side in a control cabinet without air circulation (e.g. fan), a minimum distance of 10 mm must be maintained between the evaluation units. The distance enables heat from the evaluation unit to dissipate.

When mounting several read heads, observe following minimum distance to avoid mutual interference: - for CES-A-LNA-SC-EX min. 50 mm - for CES-A-LMN-SC-EX min. �0 mm - for CEM-A-LE05K-S� -EX min. 50 mm


9

Electrical connectionWarning!

Electrical connection may only be performed by authorized personnel trained in EMC and with the device and wiring isolated.Carry out the work only if there is no ignitable atmosphere and the system is switched off.

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

All the electrical connections must either be isolated from the mains supply by a safety transformer according to EN 61558-�-6 with limited output voltage in the event of a fault, or by other equivalent isolation measures. This does not apply to the connections 13/14 and �3/�4.

Provide external contact fuses (6 A gG fuse or 6 A circuit breaker, characteris-tic B or C) for relay outputs.

The power supply must be protected with a max. 8 A fuse before terminal UB.

Use cable material made of copper with a temperature resistance of min. 75 °C.

The tightening torque for the screws on the connection terminals must be 0.6 ... 0.8 Nm.

All the output contacts must have an adequate protective circuit for capacitive and inductive loads.

If a common power supply is used, all the inductive and capacitive loads (e.g. relay contactors) connected to the power supply must be connected to appro-priate interference suppressors.

The connection cable for the read heads must only be extended using EUCH-NER-approved plug connectors and adequate consideration must be given to EMC. Intermediate terminals must not be used.

The connections for the read heads are not short circuit-proof.

The screen on the connection cable for the read head must be connected to the terminal SH1 on the evaluation unit. The portion of cable from which insula-tion is stripped should be kept as short as possible (max. 3 cm).

For use and operation as per the requirements , a power supply with the feature “for use in class � circuits” must be used. The same requirement ap-plies to the safety outputs.

If the device does not work properly, the device must be returned unopened to the manufacturer.

Connection example CES-AZ-AES-01B-EX

Important!

To achieve category 4 according to EN 13849-1 respectively EN 954-1, it is necessary to monitor the downstream contactors (here contacts of -K3 and -K4 in the feedback loop).

If only one enable path is to be used for control (e. g. of downstream contactors), failures involving a short circuit between the contacts on the enable path and, for example, the power supply must be excluded.

With reference to EN 13849-� Table D.5, this exclusion can be provided if

the cables are inside an electrical installation space and

the installation space meets the related requirements (see EN 60�04-1 or IEC 60�04-1).

This example shows only an excerpt that is relevant for connection of the CES system. The example illustrated here does not show complete system planning. The user is responsible for safe integration in the overall system.

Notes

During the teach-in operation the following conditions must be met:

There must be no state change, e.g. opening the safety guard or a change in the signal on the terminals for the start button and the feedback circuit.

The power supply must not be switched off.

If these conditions are not met, the evaluation unit switches to the safe fault state (diagnostics LED illuminates) and signals this operating fault with the STATE LED by 3 short flashes that are repeated every second. The teach-in operation must be repeated.

The number of teach-in operations is unlimited. The evaluation unit can be re-configured as often as required.

Actuators cannot be interchanged without a renewed teach-in operation.

An actuator that has not been subjected to teach-in will not be detected by the read head.

Even if only one new actuator needs to be taught, a complete new teach-in operation must be carried out as described in the section Setup.

Do not change DIP switches during operation.

Changing the configuration / new actuatorThe evaluation unit can be re-configured as often as required. For this purpose you must proceed as per the first teach-in operation according to the Setup procedure section.

Faulty actuators can be replaced. Then a complete teach-in operation must be per-formed as per the section Setup. The number of teach-in operations is unlimited.

Inspection and serviceImportant!

The evaluation unit must be replaced with a new device after 5 years of opera-tion.

Regular inspection of the following is necessary to ensure trouble-free long-term operation:

Secure fastening of the actuator and read head (use of safety screws included)

Sealing of cable entry or plug connector on the read head

Loose cable connections on the evaluation unit

Switch-off distance check

No servicing work is required on the battery-less actuator, providing the user with service-free operation.

Function test (self-test)On electromechanical safety switches or magnetic switches, the function test can be performed by cyclically opening the safety guard.

From category � as defined in EN 13849-1 respectively EN 954-1 and according to EN 60�0�-1 : 1997 (section 9.4.�.4), a function test must be performed on the entire safety system on start-up or after defined intervals.

Testing of the internal function of the safety switch CES is not necessary because the device monitors itself in real time. Welding of an output contact (relay output) is detected by the device at the latest the next time the safety guard is opened. A short circuit in the output cable is not detected by the device.

In addition, the entire safety circuit can be tested without opening the safety guard. For this purpose, opening of the safety guard can be simulated by applying �4 V DC to the test input.

The safety outputs are switched off, enabling testing of the complete safety circuit. The diagnostic output DIA of the evaluation unit is also set HIGH as a monitoring function.

When the test input is reset, the evaluation unit resets the diagnostic output DIA to LOW, the red LED switches off and normal operation is continued.

In Manual start operating mode, the start button must be pressed again to start the system.

This permits self-testing of the safety system without opening the safety guard.

EMC protection requirements As per EN 60947-5-3

1) The evaluation unit must be mounted in a control cabinet with a minimum degree of protection of IP 54.�) Supply using a safety transformer according to EN 61558-�-6 is necessary.3) Without taking into account the load currents on the monitoring outputs.4) Corresponds to the risk time according to EN 60947-5-3. This is the maximum switch-off delay for the safety outputs following removal of the actuator. In case of EMC interference in excess of the requirements in accordance with EN 60947-5-3, the switch-off delay can increase to max. �50 ms. After a brief actuation < 0.�5 s, the switch-on delay can increase to max. 3 s if this is followed immediately by further actuation.5) After the operating voltage is switched on, the relay outputs are switched off and the monitoring outputs are set LOW during the ready delay. For the visual indication of the delay, the green STATE LED flashes at a frequency of approx. 15 Hz.6) The dwell time is the time that the actuator must be inside or outside the operating distance.7) If the current load is > 100 mA, a switching frequency of 0.1 Hz should not be exceeded as this will affect the mechanical life of the relay contacts.
