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 without guard locking (type4). The device meets the requirements ac-
cording to ENIEC60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode evaluation
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 safety switches are used, a risk assessment must be performed on the machine, e.g., in accordance with:
ÌENISO13849-1
ÌENISO12100
ÌIEC62061
Correct use includes observing the relevant requirements for installation and operation, e.g.
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
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!
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.
ÌCorrect use requires observing the permissible operating parameters (see technical data).
ÌIf a data sheet is included with the product, the information on the data sheet applies.
ÌIt is only allowed to use components that are permissible in accordance with the table below.

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 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.
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

6. Function
The safety switch monitors the position of movable guards. When the actuator is moved to/removed from the actuating
range, 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 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 (multicode
detection). There is no exact comparison of the actuator code with the taught-in code in the safety switch (unicode evalua-
tion). 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.
When the guard is closed and the code is permissible, each CES-I-AS transmits a switch-specic, unique safety code sequence
with 8 x 4 bits via the AS-Interface bus.
The zero sequence is transmitted via the AS-Interface bus when the 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 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. Also see chapter 10. System status table on page 13.
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.

9.2. 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 bit sequence 0000 is transmitted, i.e. the system is in the safe state.
Important!
ÌThe teach-in operation may be performed only if the device functions awlessly. The red DIA LED
must not be illuminated.
ÌThe safety switch disables the code of the preceding device if teach-in is carried out for a new
actuator. Teach-in is not possible again immediately for this device 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-in.
ÌThe safety switch can be operated only with the last actuator taught-in.
ÌIf the switch detects the actuator that was most recently taught-in when in the teach-in standby
state, this state is ended immediately and the switch changes to normal operation.
ÌIf the actuator to be taught-in is within the actuating range for less than 60s, it will not be activat-
ed and the most recently taught-in actuator will remain saved.
9.2.1. Preparing device for the teach-in operation and teaching-in actuator
1. Connect AS-Interface bus to the safety switch.
¨A self-test is performed for approx. 0.5s. 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 < Sao).
¨Teach-in operation starts, green LED ashes (approx. 1 Hz). During the teach-in operation, 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 safety switch must then be dis-
connected from the AS-Interface bus for min. 3seconds.
