2. Correct use
Safety switches series CES-I-BR are interlocking devices without guard locking (type4). The device meets the requirements
according to ENIEC60947-5-3. 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:
Ì Starting commands that cause a dangerous machine function must become active only when the guard is closed.
Ì Opening the guard triggers a stop command.
Ì Closing a 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, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì EN60204-1, Safety of machinery – Electrical equipment of machines.
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.
Connection of several devices in a BR switch chain is permitted only using devices intended for series connection in a BR
switch chain. Check this in the instructions of the device in question.
A maximum of 20 safety switches are allowed to be operated in a switch chain.
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.

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 precautions
Safety switches fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the 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 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 fulll
a personnel 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. 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 into/out of the operating distance.
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.
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 thus possesses a high coding level.
Ì 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 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 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 operating distance.
6.2. 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 CES‑I‑BR‑… on page 21.
6.3. 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.

ar
min. 140 mm
.
Ì The operating distance changes during the mounting of the actuator as a function of the material
used for the guard.
Ì Observe direction of arrow on the device (see gure below).
Permissible approach directions
Note the following points:
Ì Actuator and safety switch must be easily accessible for inspection and replacement.
Ì Actuator and safety switch must be tted so that
- a minimum distance is maintained with a side approach direction to avoid entering the area of possible side lobes. See
chapter 11. Technical data, section Typical operating distance for the related actuator.
- when the guard is open up to the distance Sar (assured switch-off distance), a hazard is excluded.
- 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.
Ì Pay attention to the maximum tightening torque for the read head or safety switch and actuator mountings of 0.8Nm.
Ì Seal the mounting holes after mounting using the caps provided to prevent the accumulation of dirt.
Ì In order to avoid damage, the connection cable must be laid with protection in areas in which high-pressure cleaners are
used.

8. Electrical connection
The following connection options are available:
Ì Separate operation
Ì Series connection with Y-distributors
Ì Series connection, e.g. with wiring in the control cabinet.
WARNING
If there is a mistake, loss of the safety function due to 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 Do not use a control system with pulsing or switch off the pulsing function in your control system.
The device generates its own test pulses on the safety outputs. A downstream control system
must tolerate these test pulses, which may have a length of up to 300µs.
The test pulses are only output with the safety outputs switched off during device start.
Depending on the inertia of the downstream device (control system, relay, etc.), this can lead to
short switching processes.
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 transformer
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 To avoid EMC interference, the physical environmental and operating conditions at the in-
stallation 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 from devices such as frequency converters or
induction heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.
