2. Correct use
The series CES-I-AS Coded Electronic Safety switches from EUCHNER are operated as slaves on the safety bus AS-Interface
Safety at Work and function as interlocking devices with low coding level without guard locking (type4). The device meets
the requirements according to ENIEC60947-5-3.
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 safety switches are used, a risk assessment must be performed on the machine, e.g., in accordance with:
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.
Ì EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì EN 60204-1, Safety of machinery. Electrical equipment of machines. General requirements.
The safety switch must be used only in conjunction with the designated CES actuators from EUCHNER. On the use of different
actuators, 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 In the estimation of the PL for the overall system, a maximum value of 100 years can be assumed
for the MTTFD according to the limit value in EN ISO 13849-1:2008, section 4.5.2. This corresponds to a minimum value for the PFHD of 2.47 x 10-8/h.
Ì Correct use requires observing the permissible operating parameters (see Technical data).
Ì If a product 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.

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 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.com.

Non-Contact Safety Switch CES-I-AS2A-M-C04
6. Function
The safety switch monitors the position of movable safety guards. When the actuator is moved to/removed from the operating distance, a corresponding bit sequence is sent via the AS-Interface bus.
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.
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 thus possesses a high coding level.
Devices with multicode evaluation: Unlike systems with unique code detection, on multicode devices a specic 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.
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 by the switch and data is transferred.
When the safety guard is closed and the code is permissible, each CES-I-AS transmits a switch-specic, unique safety code
sequence with 8x4 bits via the AS-Interface bus.
The zero sequence is transmitted via the AS-Interface bus when the safety guard is opened.
In the event of a fault in the safety switch, the zero sequence is sent 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. 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 10. System status table on page 12.
6.2. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs
and display LEDs are described there.
