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 – Part 1: General requirements
The following components can be connected to the evaluation unit CES-A-ABA…:
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.

5. General safety instructions
WARNING
Danger to life due to improper installation or due to bypassing (tampering). Safety components fulll a personal protection function.
Ì Safety components must not be bypassed, turned away, removed or otherwise rendered ineffec-
tive. On this topic pay attention in particular to the measures for reducing the possibility of bypass­ing according to ENISO14119:2013, section 7.
Ì The switching operation must be triggered only by actuators designated for this purpose. Ì Mounting, electrical connection and setup only by authorized personnel possessing the following
knowledge:
- specialist knowledge in handling safety components
- knowledge about the applicable EMC regulations
- knowledge about the applicable regulations on occupational safety and accident prevention.
Ì The number of teach-in and switching operations is saved in the internal memory of the evaluation
unit. If necessary, this memory can be read by the manufacturer.
Important!
Prior to use, read the operating instructions and keep these in a safe place. Ensure the operating instructions are always available during mounting, setup and servicing.

6. Function
The safety system consists of three components:
Ì Coded actuator Ì Read head Ì Evaluation unit
1 read head can be connected to the evaluation unit.
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 head is fastened to the xed part of the safety guard and is connected to the evaluation unit via a two-core screened cable (terminals H11, H12 and SH1).
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 all data for match, the door monitoring output OUT (semiconductor output) is set to HIGH and the safety outputs (relay output) are enabled. The OUT LED illuminates.
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, 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 OUT.
If an internal fault occurs in the evaluation unit, the safety circuit is switched off, the diagnostic output (ERR) is set HIGH and the ERROR LED illuminates red.
The safety contacts on the safety switch CES can also switch small currents. This allows the user to connect the device directly to a safe control system.

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
IP54. 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 screen on the connection cable for the read head must be connected to the appropriate termi-
nal SH 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. 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.
Ì Use cable material made of copper wire with a temperature resistance of at least 75°C.
1) Note on the scope of the UL approval: The devices are tested according to the requirements of UL508 and CSA/ C22.2 no. 14 (protection against electric shock and re).

OUT yellow Safety circuit closed
ERROR Red
Ì Operating fault or Ì External fault (fault in the feedback loop) or Ì Teach-in operation not valid or Ì Internal device fault or Ì TST input activated (function test active)
9.2. Teach-in operation
The actuator must be assigned to the evaluation unit using a teach-in function before the system forms a functional unit.
During the teach-in operation the safety outputs are open and the door monitoring output LOW. 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 a safety door or closing a further safety door.
- The power supply must not be switched off.
Ì If these conditions are not met, the evaluation unit switches to the safe fault state (ERROR 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 Repeated teach-in of the same actuator on the same evaluation unit is not possible. Ì The number of teach-in operations on one evaluation unit is limited to a maximum of 8 Ì The evaluation unit can only be operated with the last actuator taught 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 as described in the section Setup.
Ì When the evaluation unit is switched on (operating voltage is applied), the STATE LED signals the
number of possible remaining teach-in operations (see system status table)
Ì After the eighth teach-in operation or if an "old" actuator is placed against the read head, the sys-
tem automatically switches to the teach-in mode. In both cases, a teach-in operation with a dura­tion of 60 seconds is started; however, the last actuator code remains active (see system status table) in the memory – a new code is not taught.

9.2.1. Carrying out teach-in for rst actuator (default setting on delivery)
To trigger the rst teach-in operation, the user must perform the following actions in the stipulated order:
1. Start teach-in operation
- Switch on operating voltage (STATE LED ashes at approx. 4Hz)
- Close door to be monitored (the actuator must be in the operating distance of the read head)
- 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. 60 seconds)
2. End teach-in operation
- Interrupt operating voltage for at least 10 seconds (code for the actuator taught-in is activated)
3. Check safety guard for effectiveness
9.2.2. Carrying out teach-in for a new actuator
A maximum of 8 teach-in operations can be undertaken. The number of teach-in operations already undertaken is signaled after step 6 via the ashing sequence on the STATE LED (see 10. System status table on page 17, section State indication).
Faulty actuators can be replaced. Then a complete teach-in operation must be performed as per this section.
To trigger a further teach-in operation, the user must perform the following actions in the stipulated order:
1. Start teach-in operation
- Switch on operating voltage
- Close door to be monitored (the new actuator must be in the operating distance of the read head)
- 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. 60 seconds)
2. End teach-in operation
- Interrupt operating voltage for at least 10 seconds (code for the new actuator taught-in is activated)
The newly taught-in actuator is saved and the old actuator deactivated.
3. Check safety guard for effectiveness

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 up to three times. The STATE LED then illuminates continuously. The OUT and ERROR LEDs do not light up.
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 ERROR 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 ERR on the eval­uation unit is also set HIGH as a monitoring function.
When test input TST is reset, the evaluation unit resets the diagnostic output ERR to LOW, the red LED switches off and normal operation is continued.
Important!
After the self-test, the test input TST must be connected to 0 V again or must be disconnected.

1) Without taking into account the load currents on the monitoring outputs.
2) 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.
3) After the operating voltage is switched on, the relay outputs are switched off and the door monitoring output is set to LOW potential during the ready delay.
4) The dwell time of an actuator inside and outside the operating distance must be at least 0.5s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
5) 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.
6) Not short circuit-proof.
