2. Correct use
Safety switches series CES-AP are interlocking devices without guard locking (type4). The device complies with the requirements according to ENIEC60947-5-3. Devices with unicode evaluation possess a high coding level; devices with multicode
evaluation feature a low coding level.
In combination with a movable safety guard and the machine control, this safety component 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 ENISO12100 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:
Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
Ì IEC62061, 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, particularly based on the following
standards:
Ì ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO14119 (supersedes EN1088), Safety of machinery – Interlocking devices associated with guards – Principles
for design and selection
Ì EN60204-1, Safety of machinery – Electrical equipment of machines – Part 1: General requirements
The safety switch is only allowed to be operated in conjunction with the intended CES actuators from EUCHNER 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!
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 ENISO13849-2.
Ì It 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 safety guard position
(interlocking device according to ENISO14119)
Ì Safety function:
- The safety outputs are switched off when the safety guard is open (see chapter 6.4. Switching states on page 7).
Ì Safety characteristics: category, Performance Level, PFH
d
(see chapter 6. Technical data on page 19).
4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety instructions
Safety switches fulll personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safety guard particularly
Ì after any setup work
Ì after the replacement of a system component
Ì after an extended period without use
Ì after every fault
Independent of these checks, the safe function of the safety guard 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 perform
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 ENISO14119:2013, section 7.
Ì The switching operation must be triggered only by actuators designated for this purpose.
Ì Prevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys for releases, for example.
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.
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. EUCHNER cannot provide any
warranty in relation to the readability of the CD for the storage period required. For this reason you
should archive a printed copy of the operating instructions. You can download the operating instructions
from www.EUCHNER.de.

6. Function
The safety switch monitors the position of movable safety guards. The safety outputs are switched on/off when the actuator
moves into/out of the operating distance.
The system consists of the following components: coded actuator (transponder) and switch.
Whether the complete actuator code of the device is taught in (unicode) or not (multicode) depends on the respective version.
Ì Devices 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 thereby possesses a high coding level.
Ì Devices with multicode evaluation: Unlike systems with unique code detection, on multicode devices a specic code
is not polled 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.
When the safety guard is closed, the actuator is moved towards the safety switch. When the switch-on distance is reached,
power is supplied to the actuator via the switch and data transfer takes place.
If a permissible code is detected, the safety outputs are switched on.
The safety outputs are switched off when the safety 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 failures 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 operating distance.
6.2. Diagnostics output
The diagnostics 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 operating distance.
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. Also see chapter 5. System status table on page 18.
6.4. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs
and indicating LEDs are described there.
Safety guard closed
(actuator in operating distance and permissible
coding detected)
Safety guard open
(actuator not in operating distance)

9. Electrical connection
WARNING
In case of an error, loss of the safety function through incorrect connection.
Ì To ensure safety, both safety outputs must always be evaluated.
Ì Monitoring outputs must not be used as safety outputs.
Ì Lay the connection cables with protection to prevent the risk of short circuits.
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connection.
Ì The device generates its own clock signal on the output lines OA/OB. A downstream control sys-
tem must tolerate these pulses, which may have a length of up to 0.4ms.
No clock pulses are output when the safety outputs are switched off.
Ì The inputs on an evaluation unit connected must be positive-switching, as the two outputs on the
safety switch deliver a level of +24V in the switched-on state.
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 (PELV).
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. RC interference suppression units
must not be used.
Ì Power 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.
Ì In order to 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
EN60204-1:2006, section 4.4.2 (EMC).
Ì Please pay attention to any interference elds in case of 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.

9.7. Notes on operation with safe control systems
Please observe the following requirements for connection to safe control systems:
Ì Use a common power supply for the control system and the connected safety switches.
Ì A pulsed power supply must not be used for U
B
. Tap the supply voltage directly from the power supply unit. If the supply
voltage is connected to a terminal of a safe control system, this output must provide sufcient electrical current.
Ì The safety outputs (OA and OB) can be connected to the safe inputs of a control system. Prerequisite: The input must
be suitable for pulsed safety signals (OSSD signals, e.g. from light curtains). The control system must tolerate test pulses on the input signals. This normally can be set up by parameter assignment in the control system. Observe the notes
of the control system manufacturer. For the pulse duration of your safety switch, please refer to the chapter 6. Techni-
cal data on page 19.
A detailed example of connecting and setting the parameters of the control system is available for many devices at www.
euchner.de in the area Download » Applications » CES. The features of the respective device are dealt with there in greater
detail.
9.8. Devices for direct connection to IP65 eld modules
The version CES-AP-...-SB-... (M12, 5-pin; pin 5 not assigned) is optimized for connection to decentralized peripheral systems
with M12 plug connector, such as the ET200pro series from Siemens. The devices are parameterized and connected like
an OSSD (e.g. like light curtains).
If ying leads are used, connection to IP20 input and output modules (e.g. ET200s) is naturally also possible.
Important!
Observe the following notes prior to connection:
Ì Parameter assignment must be performed for the input/output modules (see application example
at www.euchner.de, in the area Download ¨ Applications ¨ CES).

10.2. Teach-in function for actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.
During a teach-in operation, the safety outputs and the monitoring output OUT are switched off, i.e. the system is in the
safe state.
Important!
Ì The teach-in operation may be performed only if the device functions awlessly. The red DIA LED
must not be illuminated.
Ì The safety switch disables the code of the previous actuator if teach-in is carried out for a new
actuator. Teach-in is not possible again immediately for this actuator if a new teach-in operation is
carried out. The disabled code is released again in the safety switch only after a third code has
been taught.
Ì The safety switch can only be operated with the last actuator taught.
Ì If the switch detects the actuator that was most recently taught when in teach-in standby state,
this state is ended immediately and the switch changes to normal state.
Ì If the actuator to be taught in is within the operating distance for less than 60s, it will not be acti-
vated and the most recently taught in actuator will remain saved.
10.2.1. Preparing device for the teach-in operation and teaching in actuator
1. Apply operating voltage to the safety switch.
¨ A self-test is performed for approx. 0.5s. After this, the LED ashes cyclically three times and signals that it is in
standby state for teach-in.
Standby state for teach-in remains active for approx. 3 minutes.
2. Move new actuator to the read head (observe distance < S
ao
).
¨ Teach-in operation starts, green LED ashes (approx. 1 Hz). During teach-in, the safety switch checks whether the actuator
is a disabled actuator. Provided this is not the case, the teach-in operation is completed after approx. 60 seconds, and
the green LED goes out. The new code has now been stored, and the old code is disabled.
3. To activate the new actuator code from the teach-in operation in the safety switch, the operating voltage to the safety
switch must then be switched off for min. 3 seconds.

6.1.1. Typical system times
Please refer to the technical data for the exact values.
Ready delay: After switching on, the unit carries out a self-test. The system is ready for operation only after this time.
Switch-on time of safety outputs: The max. reaction time t
on
is the time from the moment when the actuator is in the
operating distance to the moment when the safety outputs switch on.
Risk time according to EN 60947-5-3: If an actuator moves outside the operating distance, the safety outputs (OA and
OB) are deactivated at the latest after the risk time.
Discrepancy time: The safety outputs (OA and OB) switch with a slight time offset. They assume the same signal state at
the latest after the discrepancy time.
Test pulses at the safety outputs: The device generates its own test pulses on the output lines OA/OB. A downstream
control system must tolerate these test pulses.
This can usually be set up in the control systems by parameter assignment. If parameter assignment is not possible for your
control system or if shorter test pulses are required, please contact our support organization.
The test pulses are also output when the safety outputs are switched off.
