2. Correct use
Evaluation units of the series CES-AZ are used to evaluate safety-related signals from EUCHNER read heads. Depending
on the read heads used, the system can form an interlocking device with or without guard locking. The system meets the
requirements according to ENIEC60947-5-3.
The following applies in combination with a CES or CEM read head:
The system consists of evaluation unit, read head and actuator. It forms an interlocking device with low coding level
(type4).
In combination with a movable guard and the machine control, this system prevents dangerous machine functions
from occurring while the guard is open. A stop command is triggered if the guard is opened during the dangerous
machine function.
This means:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed.
ÌOpening the guard triggers a stop command.
ÌClosing a 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.
The following applies in combination with a CET read head:
The system comprising evaluation unit, read head with guard locking and actuator forms an interlocking device with
guard locking featuring a low coding level (type4).
In combination with a movable guard and the machine control, this system prevents the guard from being opened
while a dangerous machine function is being performed.
This means:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed
and locked.
ÌThe guard locking must not be unlocked until the dangerous machine function has ended.
Closing and locking a 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

3. Description of the safety function
Devices from this series feature the following safety functions:
The following applies in combination with read heads without guard locking (CES read heads) and read heads with guard
locking for process protection (CEM read heads):
Monitoring of the position of a guard
(interlocking device according to EN ISO 14119)
ÌSafety function:
- The safety contacts are switched off when the guard is open (see chapter 11. Technical data on page 16).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 11. Technical data on page 16).
The following applies in combination with read heads with guard locking (CET-AX):
Monitoring of guard locking and the position of the guard
(interlocking device with guard locking according to EN ISO 14119)
ÌSafety function (see chapter 11. Technical data on page 16):
- The safety contacts are switched off when guard locking is released (monitoring of the locking element).
- The safety contacts are switched off when the guard is open.
- Guard locking can be activated only when the actuator is located in the switch head (prevention of inadvertent locking
position (faulty closure protection)).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 11. Technical data on page 16).
Control of guard locking
ÌIf the device is used as guard locking for personnel protection, the control of the guard locking must be regarded as a
safety function.
ÌThe device does not feature a safety characteristic for the control of the guard locking, because the guard locking so-
lenoid is completely disconnected from outside the device (no control function within the device). It therefore does not
contribute to the failure probability.
ÌThe safety level for the control of guard locking is determined exclusively by the external control (e.g. PFHDext. for the
standstill monitor).

4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety regulations are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety precautions
WARNING
Danger to life due to improper installation or due to bypassing (tampering). Safety components fulll
a personnel protection function.
ÌSafety 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 bypass-
ing according to ENISO14119:2013, section 7.
ÌThe switching operation must be triggered only by actuators designated for this purpose.
ÌPrevent bypassing by means of replacement actuators. For this purpose, restrict access to actua-
tors and to keys for releases, for example.
ÌMounting, 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 operational safety and accident prevention.
ÌThe number of switching operations is saved in the internal memory of the evaluation unit. If neces-
sary, 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. For this reason you should
archive a printed copy of the operating instructions. You can download the operating instructions from

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.
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.
Unlike systems with unique code detection, on multicode devices a specic code is not requested 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 taught-in code in the safety switch (unique code detection). The system possesses
a low coding level.
The read head is fastened to the xed part of the guard and is connected to the evaluation unit via a two-core shielded cable
(terminals H11, H12 and SH1).
The actuator fastened to the movable part of the 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.
If a permissible code is detected, 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 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
IP54. 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 dis-
tance enables the heat from the evaluation unit to dissipate.
Important!
ÌFrom the assured release 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 assured operating distance 0.8xSao or closer when the guard is closed (see sec-
tion Actuating ranges). 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 actuating range for the related actuator.
- a hazard is excluded until the assured release distance (Sar) is reached when the guard is open.
- the actuator is positively mounted on the 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 fastenings of 1Nm. For
read heads/actuators made of PE-HD, the maximum tightening torque is only 0.5Nm.

8. Electrical connection
WARNING
If there is a mistake, loss of the safety function due to incorrect connection.
ÌMonitoring outputs must not be used as safety outputs.
ÌLay the connecting cables with protection to prevent the risk of short circuits.
NOTICE
Risk of damage to equipment or malfunctions as a result of incorrect connection.
ÌAll 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 equiv-
alent isolation measures.
ÌAll 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.
ÌThe tightening torque for the screws on the connection terminals must be 0.6…0.8Nm.
ÌThe 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.
ÌThe shield 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!
ÌFor use and operation as per the requirements1), a power supply with the feature “for use in
Class 2 circuits” must be used.
Alternative solutions must comply with the following requirements:
- 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.
1) Note on the scope of the UL approval: The devices have been tested as per the requirements of UL508 and CSA/C22.2 no. 14 (protection against electric shock
and re).
8.2. Safety in case of faults
ÌThe operating voltage UBis reverse polarity protected.
ÌThe connections for the read heads are not short circuit-proof.
ÌA short circuit between 13/14 and 23/24 can be detected only by means of external pulsing.
ÌA short circuit in the cable can be excluded by laying the cable with protection.
8.3. Fusing of the power supply and the safety contacts
ÌProvide external contact fuses (6AgG fuse or 6A circuit breaker, characteristic B or C) for relay outputs.
ÌThe power supply must be protected with a max. 8A fuse ahead of terminal UB.

Important!
To achieve category 3 according to EN ISO 13849-1, it is necessary to monitor the downstream
contactors (here: contacts on -K3 and -K4 in the feedback loop).
This example shows only an excerpt that is relevant for the connection of the CES system. The example
illustrated here does not show complete system planning. The user is responsible for safe integration
into the overall system.
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 ISO 13849-2 Table D.5, this exclusion can be provided if
Ìthe cables are inside an electrical installation space and
Ìthe enclosure meets the related requirements (see EN 60204-1 or IEC60204-1).

9.2. 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.
ÌBefore carrying out the functional check, make sure that there are no persons in the danger zone.
ÌObserve the valid accident prevention regulations.
1. Switch on operating voltage.
- The safety switch carries out a self-test.
The green STATE LED ashes 3 times.
The STATE LED then illuminates continuously.
The OUT and ERROR LEDs do not light up.
2. Close all 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 guard.
- The machine must switch off and it must not be possible to start it as long as the guard is open.
- The green STATE LED illuminates continuously; the OUT and ERROR LEDs do not illuminate.
Repeat steps 2…4 separately for each guard.
9.2.1. Self-test with test input TST
On electromechanical safety switches or magnetic switches, the function test can be performed by cyclically opening the
guard.
From category 2 according to ENISO13849-1, EN 60204-1 : 1997 (section 9.4.2.4) requires a function test 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 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 guard. For this purpose, opening of the 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 OFF time 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 actuating range 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.
