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:
ÌStarting commands that cause a dangerous machine function must become active only when the safety guard is closed.
ÌOpening the safety guard triggers a stop command.
ÌClosing 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:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
ÌIEC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:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
ÌEN60204-1, Safety of machinery – Electrical equipment of machines – Part 1: General requirements

6. Function
The safety system consists of three components:
ÌCoded actuator
ÌRead head
ÌEvaluation 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.
ÌRead heads and actuators must not be used as a mechanical end stop.
ÌObserve EN ISO 14119:2013, sections 5.2 and 5.3, for information about fastening the safety
switch and the actuator.
ÌObserve EN ISO 14119:2013, section 7, for information about reducing the possibilities for by-
passing an interlocking device.
ÌThe 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.
ÌIf 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!
ÌFrom the assured switch-off distance Sar, the safety outputs are safely shut down.
ÌWhen mounting several read heads, observe the stipulated minimum distance to avoid mutual in-
terference.
- For CES-A-LNA/-LCA smin=50mm
- For CES-A-LMN smin=20mm
- For CES-A-LQA smin=80mm

Note the following points:
ÌActuator 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.
ÌPay 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.

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!
ÌThe 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.
ÌDuring 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.
ÌIf 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 re-
peated every second. The teach-in operation must be repeated.
ÌRepeated teach-in of the same actuator on the same evaluation unit is not possible.
ÌThe number of teach-in operations on one evaluation unit is limited to a maximum of 8
ÌThe evaluation unit can only be operated with the last actuator taught
ÌActuators cannot be interchanged without a renewed teach-in operation.
ÌAn actuator that has not been subjected to teach-in will not be detected by the related read head.
ÌEven 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.
ÌWhen 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)
ÌAfter 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 dura-
tion 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.

9.3.1. 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 eval-
uation 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.
