2. Correct use
Safety switches series CES-AP are interlocking devices without guard locking (type4). The device meets the requirements
according to ENIEC60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode eval-
uation possess a low coding level.
In combination with a movable guard and the machine control, this safety component 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ISO12100 or relevant C-standards.
Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following
standards:
ÌENISO13849-1
ÌENISO12100
ÌIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
The safety switch is only allowed to be operated in conjunction with the intended EUCHNER CES actuators and the related
connection components from EUCHNER. On the use of different actuators or other connection components, EUCHNER
provides no warranty for safe function.
Important!
ÌThe 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.
ÌIt is only allowed to use components that are permissible in accordance with the table below.

3. Description of the safety function
Devices from this series feature the following safety functions:
Monitoring of the guard position
(interlocking device according to ENISO14119)
ÌSafety function:
- The safety outputs are switched off when the guard is open (see chapter 6.4. Switching states on page 7).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 11. Technical data on page 17).
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
Safety switches fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safeguard particularly
Ìafter any setup work
Ìafter the replacement of a system component
Ìafter an extended period without use
Ìafter every fault
Independent of these checks, the safe function of the safeguard should be checked at suitable intervals as part of the
maintenance schedule.
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 ineffective.
On this topic pay attention in particular to the measures for reducing the possibility of bypassing
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 (only for multicode evaluation). For this pur-
pose, restrict access to actuators 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.
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
www.euchner.com.

6. Function
The safety switch monitors the position of movable guards. The safety outputs are switched on/off when the actuator is
moved to/removed from the actuating range.
The system consists of the following components: coded actuator (transponder) and switch.
Whether the device learns the complete actuator code (unicode) or not (multicode) depends on the respective version.
ÌDevices with unicode evaluation: The actuator must be assigned to the safety switch by a teach-in operation so that it
is detected by the system. This unambiguous assignment ensures a particularly high level of protection against tampering.
The system thus possesses a high coding level.
ÌDevices with multicode evaluation: Unlike systems with unicode evaluation, 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 (multi-
code evaluation). There is no exact comparison of the actuator code with the taught-in code in the safety switch (unicode
evaluation). The system possesses a low coding level.
When the guard is closed, the actuator is moved towards the safety switch. When the operating distance is reached, power
is supplied to the actuator by the switch and data are transferred.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the guard is opened.
In the event of a fault in the safety switch, the safety outputs are switched off and the DIA LED illuminates red. The occurrence
of faults is detected at the latest on the next demand to close the safety outputs (e.g. on starting).
6.1. Door monitoring output
The door monitoring output is switched on as soon as a valid actuator is detected in the actuating range.
6.2. Diagnostic output
The diagnostic output is switched on in the event of a fault (switch-on condition as for DIA LED).
6.3. Limit-range monitoring
If the safety door with the actuator should settle over time, the actuator can drift out of the read head actuating range. The
device recognizes this situation and indicates that the actuator is in the limit range by ashing the STATE LED. This allows
the safety door to be readjusted in time. See also chapter 10. System status table on page 16.
6.4. Switching states
The detailed switching states for your switch can be found in the system status table (see chapter 10. System status table
on page 16). All safety outputs, monitoring outputs and display LEDs are described there.
Guard closed
(actuator in the actuating range
and permissible code detected)
Guard open
(actuator not in the actuating range)
Safety outputs OA and OB on off
Monitoring output OUT on off

7. Mounting
CAUTION
Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise
rendered ineffective.
ÌObserve ENISO14119:2013, section 7, for information about reducing the possibilities for bypassing
an interlocking device.
NOTICE
Risk of damage to equipment and malfunctions as a result of incorrect installation.
ÌSafety switches and actuators must not be used as an end stop.
ÌObserve ENISO 14119:2013, sections 5.2 and 5.3, for information about mounting the safety
switch and the actuator.
ÌFrom the assured release distance Sar, the safety outputs are safely shut down.
ÌWhen mounting several safety switches/actuators, observe the stipulated minimum distance to
avoid mutual interference.
min. 400 mm
ÌThe operating distances change during the mounting of the actuator as a function of the material
used for the guard.
Permissible installation positions
Note the following points:
ÌActuator and safety switch must be easily accessible for inspection and replacement.
ÌActuator and safety switch must be tted so that
- the front faces are at the minimum operating distance 0.8xSao or closer when the guard is closed. To avoid entering the
area of possible side lobes, a minimum distance is to be maintained in case of a side approach direction. See chapter
11. Technical data, section Typical actuating range for the related actuator.
- when the guard is open up to the distance Sar (assured release distance), a hazard is excluded.
- the actuator is positively mounted on the guard, e.g. by using the safety screws included.
- The safety screws 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.

8. Electrical connection
WARNING
In the event of a fault, loss of the safety function due to incorrect connection.
ÌTo ensure safety, both safety outputs must always be evaluated.
ÌMonitoring outputs must not be used as safety outputs.
ÌLay the connecting cables with protection to prevent the risk of short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
ÌThe device generates its own clock signal on the output lines OA/OB. A downstream con-
trol system must tolerate these test pulses, which may have a length of up to 0.3ms.
No test pulses are output when the safety outputs are switched off.
ÌThe inputs on a connected evaluation unit must be positive switching, as the two outputs on the safety
switch deliver a level of +24V in the switched-on state.
ÌAll the electrical connections must either be isolated from the mains supply by a safety transformer
according to IEC 61558-2-6 with limited output voltage in the event of a fault, or by other equivalent
insulation measures (PELV).
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. RC interference suppression units must
not be used.
ÌPower devices which are a powerful source of interference must be installed in a separate location
away from the input and output circuits for signal processing. The cable routing for safety circuits
should be as far away as possible from the cables of the power circuits.
ÌTo avoid EMC interference, the physical environmental and operating conditions at the installation
site of the device must comply with the requirements according to the standard EN60204-1 (EMC).
ÌPay attention to any interference elds from devices such as frequency converters or induction
heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.
Important!
If the device does not appear to function when operating voltage is applied (e.g. green STATE LED
does not ash), the safety switch must be returned unopened to the manufacturer.
