2. Correct use

Evaluation units of the series CES-A are used to evaluate safety-related signals from EUCHNER read heads. The system
forms an interlocking device without guard locking. It meets the requirements according to ENIEC60947-5-3.

The system consists of evaluation unit, read head and actuator. It forms an interlocking device with high coding level (type4).

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

This means:

Ì Starting commands that cause a dangerous machine function must become active only when the safety guard is closed.
Ì Opening the safety guard triggers a stop command.
Ì Closing a safety guard must not cause automatic starting of a dangerous machine function. A separate start command

must be issued. For exceptions, refer to EN 12100 or relevant C-standards.

Before use, a risk assessment must be performed on the machine, e.g. according to the following standards:

Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
Ì IEC62061, Safety of machinery – Functional safety of safety-related electrical, electronic and programmable electronic

control systems.

Correct use includes observing the relevant requirements for installation and operation, e.g. according to the following
standards:

Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì EN60204-1, Safety of machinery – Electrical equipment of machines.

The following components can be connected to the evaluation unit CES-A-AEA…:

Ì CES read heads
Ì CEM read heads
Ì CET read heads

For further information, refer to the operating instructions of the corresponding component and to Table 1: Possible com‑

binations for CES components on page 6.

Important!

Ì The user is responsible for the proper 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.

Ì Correct use requires observing the permissible operating parameters (see technical data).
Ì If a data sheet is included with the product, the information on the data sheet applies.
Ì It is only allowed to use components that are permissible in accordance with the table below.

(translation of the original operating instructions) 2084606-19-09/17

6. Function

The safety system consists of three components:

Ì Coded actuator
Ì Read head
Ì Evaluation unit

The number of read heads that can be connected depends on the evaluation unit:

Ì CES-A-AEA-02B:  two read heads
Ì CES-A-AEA-04B:  four read heads

The evaluation unit can be congured so that a start button (monitoring of the falling edge) and a feedback loop can be
connected to monitor external relays and contactors. The individual conguration is dened by a setup procedure (see
chapter 9. Setup on page 15).

The read heads and actuators are assigned to the device in a special teach-in operation.

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 xed part of the safety guard and are each connected to the evaluation unit via a two­core shielded cable (terminals H.1, H.2 and SH.).

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 read head by induction and data can be transferred.
The read code is compared with the taught-in code in the evaluation unit.

If the data match, door monitoring output O1…O2 or O1…O4 (semiconductor output) on the related read head is set to HIGH.
If all data for all read heads activated match, the safety outputs (relay output) are then enabled. The OUT LED illuminates.

Optionally, a feedback loop can be connected to the evaluation unit. The evaluation unit can then only be started with the
feedback loop closed. A welded contactor contact in the enable path will thus be detected the next time the machine is started.

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

When a safety guard is opened or when guard locking is released, 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 all safety doors can be polled via the outputs O1…
O2 or O1…O4 .

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

7. Mounting

NOTICE

Device damage due to improper installation or unsuitable ambient conditions.

Ì Read heads and actuators must not be used as a mechanical end stop.
Ì Observe EN ISO 14119:2013, sections 5.2 and 5.3, for information about fastening the safety

switch and the actuator.

Ì Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for by-

passing an interlocking device.

Ì The evaluation unit must be mounted in a control cabinet with a minimum degree of protection of

IP54. A snap-in element on the rear of the device is used for fastening to a mounting rail.

Ì 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. This dis­tance enables the heat from the evaluation unit to dissipate.

Important!

Ì From the assured switch-off distance S

ar

, the safety outputs are safely shut down.

Ì When mounting several read heads, observe the stipulated minimum distance to avoid mutual in-

terference.

Note the following points:

Ì Actuator and read head must be tted so that

- the front faces are at the minimum switch-on distance 0.8xSao or closer when the safety guard is closed (see section
Operating distances). To avoid entering the area of possible side lobes, a minimum distance is to be maintained in
case of a side approach direction. See section Typical operating distance for the related actuator.

- a hazard is excluded until the assured switch-off distance (Sar) is reached when the safety guard is open.

- the actuator is positively mounted on the safety guard, e.g. by using the safety screws included.

- they cannot be removed or tampered with using simple means.

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

read heads/actuators made of PE-HD, the maximum tightening torque is only 0.5Nm.

8. Electrical connection

WARNING

In case of an error, loss of the safety function through incorrect connection.

Ì Monitoring outputs must not be used as safety outputs.
Ì Lay the connection cables with protection to prevent the risk of short circuits.

NOTICE

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

Ì All the electrical connections must either be isolated from the mains supply by a safety transform-

er according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equiv­alent isolation measures.

Ì 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. The switch-on current may have to
be limited for capacitive loads.

Ì The tightening torque for the screws on the connection terminals must be 0.6…0.8Nm.
Ì The connection cable for the read heads must only be extended using EUCHNER plug connectors,

and adequate consideration must be given to EMC. Intermediate terminals must not be used.

Ì The shield on the connection cable for the read head must be connected to the appropriate termi-

nal SH1…4 on the evaluation unit. The portion of cable from which insulation is stripped should
be kept as short as possible (max. 3cm).

8.1. Notes about

Important!

Ì For use and operation as per the requirements

1)

, a power supply with the feature “for use in

class 2 circuits” must be used.

Ì TST input activated (function test active)

9.2. Teach-in operation

Before the system forms a functional unit, the parameters are set in the evaluation unit using a teach-in operation (number
of connected read heads, assignment of the actuators to the read heads, with or without automatic start, with or without
feedback loop). During this process the read heads are activated and the actuator code taught-in.

These conguration parameters are saved in the device.

During the teach-in operation the safety outputs are open. The system is in the safe state.

Important!

Ì The teach-in operation can differ for read heads that are not described in this document. Observe

the information in the operating instructions for the read head used.

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

- There must be no state change, e.g. opening or closing of a safety door or a change in the sig­nal on the terminals for the start button and the feedback loop.

- The power supply must not be switched off.

Ì 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 three short ashes that are re­peated every second. The teach-in operation must be repeated.

Ì The number of teach-in operations is unlimited. The evaluation unit can be re-congured as often

as required.

Ì Actuators cannot be interchanged without a renewed teach-in operation.
Ì An actuator that has not been subjected to teach-in will not be detected by the related read head.
Ì Even if only one new actuator needs to be taught, a complete new teach-in operation must be car-

ried out.

Ì Do not change DIP switches during operation.

To trigger a teach-in operation, the user must perform the following actions in the stipulated order:

1. Prepare for teach-in operation

- Switch off power supply U

B

- Fit a jumper between terminals J1 and J2

2. Set required conguration on DIP switches

(translation of the original operating instructions) 2084606-19-09/17

4. Start teach-in operation

- Switch on operating voltage

- Wait for self-test (STATE LED ashes for approx. 10 seconds at 15Hz)

- Teach-in operation starts (STATE LED ashes at approx. 1Hz)

- Wait for acknowledgment of the teach-in operation (STATE LED goes out after approx. 10 seconds)

5. End teach-in operation

- Remove jumper between J1 and J2

- For Manual start operating mode: start button must be connected

- For With feedback operating mode: feedback loop must be connected

- Interrupt operating voltage for at least 10 seconds

- Wait for self-test (STATE LED ashes for approx. 10 seconds at 15Hz)

6. Check all safety guards for effectiveness

9.2.1. Changing the conguration/new actuators

The evaluation unit can be re-congured as often as required. For this purpose you must proceed as per the rst teach-in
operation according to the section 9.2. Teach‑in operation on page 15. Faulty actuators can be replaced. Then again a
complete teach-in operation must be performed.

9.3. Functional check

After installation and any fault, the safety function must be fully checked. Proceed as follows:

WARNING

Danger of fatal injury as a result of faults in installation and functional check.

Ì Before carrying out the functional check, make sure that there are no persons in the danger area.
Ì Observe the valid accident prevention regulations.

1. Switch on operating voltage.

- The safety switch carries out a self-test.
The green STATE LED ashes for approx. 10 seconds at 15Hz.
The STATE LED then illuminates continuously.
The OUT and DIA LEDs do not illuminate.

2. Close all safety guards.

- The machine must not start automatically.

- The green STATE LED and the yellow OUT LED light up continuously.

3. Enable operation in the control system.

4. Open the safety guard.

- The machine must switch off and it must not be possible to start it as long as the safety guard is open.

- The green STATE LED illuminates continuously; the OUT and DIA LEDs do not illuminate.

Repeat steps 2…4 separately for each safety guard.

9.3.1. Self-test with test input TST

On electromechanical safety switches or magnetic switches, the function test can be performed by cyclically opening the
safety guard.

From category 2 according to ENISO13849-1 and in accordance with EN 60204-1 : 1997 (chapter 9.4.2.4), a function
test must be performed on the entire safety system on start-up or after dened intervals.

Testing of the internal function of the unit 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 24 V DC to the test input TST.

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

When test input TST 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.

Important!

After the self-test, the test input TST must be connected to 0 V again or must be disconnected.

- DIP switch setting has been changed without teach-in operation

- The jumper (J1, J2) was tted with power supply switched on

- Closed feedback loop (Y1,Y2) present, although a feedback loop was not present during teach-in

- 24 V signal present at the start button input (S) although teach-in was performed with “Automatic start” operating
mode.

Fault in feedback loop
Possible causes:

- Malfunction of the monitored contactor

- Following removal from the operating distance, actuator is not outside the operating distance long enough; as a
result the feedback loop cannot be closed in this short time. Note the release time for the monitored contactor.

- Feedback loop was not closed on starting the evaluation unit

- Feedback loop was not closed on applying the operating voltage +UB.

1) Without taking into account the load currents on the monitoring outputs.

2) If a switching current > 300 mA in conjunction with a switching voltage > 15 V or an inductive or capacitive load is switched once using the relay outputs, it is no longer possible to reliably switch small currents
(< 15 mA) due to the contact erosion on the gold contacts.

3) 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. 430 ms. After a brief actuation < 0.4 s, the switch-on delay can increase to max. 3 s if this is followed immediately by further actuation.

4) After the operating voltage is switched on, the relay outputs are switched off and the monitoring outputs are set to LOW potential during the ready delay. For the visual indication of the delay, the green STATE
LED ashes at a frequency of approx. 15Hz.

5) The dwell time is the time that the actuator must be inside or outside the operating distance.

6) In case of monitoring with feedback loop, the actuators must remain outside the operating distance, e.g. with a door open, until the feedback loop is closed.
