2. Correct use
Safety switches series CES-I-BR 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, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
ÌIEC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, particularly based on the following
standards:
ÌENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
ÌENISO14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
ÌEN60204-1, 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!
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 6.3. Switching states on page 7).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 11. Technical data on page 22).
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 fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the guard 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 guard should be checked at suitable intervals as part of the mainte-
nance 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.
ÌPrevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, 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 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.
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 tam-
pering. The system thus possesses a high coding level.
ÌDevices with multicode evaluation: Unlike systems with unique code detection, 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
(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.

7. Installation
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 by-
passing 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 fastening the safety
switch and the actuator.
ÌFrom the assured switch-off distance Sar, the safety outputs are safely shut down.
ÌWhen mounting several safety switches, observe the stipulated minimum distance to avoid mutual
interference.

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
- 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.
ÌPay attention to the maximum tightening torque for the read head or safety switch and actuator mountings of 0.8Nm.
ÌSeal the mounting holes after mounting using the caps provided to prevent the accumulation of dirt.
ÌIn 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:
ÌSeparate operation
ÌSeries connection with Y-distributors
ÌSeries connection, e.g. with wiring in the control cabinet.
WARNING
If there is a mistake, 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 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.
ÌDo 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 300µs.
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.
ÌThe inputs on an evaluation unit connected 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
isolation 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 in-
stallation site of the device must comply with the requirements according to the standard
EN60204-1:2006, section 4.4.2 (EMC).
ÌPlease 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 man-
ufacturer.
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.

8.5.1. Determining cable lengths using the example table
Example: six switches are to be used in series. Cabling with a length of 40m is routed from a safety relay in the control
cabinet to the last switch (#6). Cables with a length of 20m each are connected between the individual safety switches.

Figure 1: Circuit example with six CES-I-BR
A safety relay is connected downstream which consumes 75mA at each of the two safety inputs.
All the relevant values can now be determined using the example table:
1. Select the corresponding section in the column n (max. number of switches). Here: six switches.
2. In column IOD (possible output current per channel FO1A/FO1B), nd a current greater than or equal to 75mA. Here:
100mA.
¨It is then possible to determine the maximum cable length from the last switch (#6) to the control system from column
l1. Here: a length of 50m is permitted.
Result: The desired cable length l1of 40m is below the permitted value from the table. The overall length of the switch
chain lmax of 140m is less than the maximum value of 200m.
¨The planned application is therefore functional in this form.

8.9. Connection of several devices in a switch chain
Important!
ÌA BR switch chain may contain a maximum of 20 safety switches.
ÌThe example shows only an excerpt that is relevant for connection of the CES system. The exam-
ple illustrated here does not show complete system planning. The user is responsible for safe inte-
gration into the overall system. Detailed application examples can be found at www.euchner.com.
Simply enter the order number in the search box. You will nd all available connection examples for
the device in Downloads.
The series connection is shown here based on the example of the version with plug connectors M12. The switches are con-
nected one behind the other with the aid of pre-assembled connection cables and Y-distributors. If a safety door is opened or
if a fault occurs on one of the switches, the system shuts down the machine. A higher-level control system cannot, however,
detect which safety door is open or on which switch a fault has occurred with this connection technology.
The series connection can also be realized via additional terminals in a control cabinet.
The safety outputs are permanently assigned to the respective safety inputs of the downstream switch. FO1A must be routed
to FI1A and FO1B to FI1B. If the connections are interchanged (e.g. FO1A to FI1B), the device will switch to the fault state.

8.10. Notes on operation with safe control systems
Please observe the following requirements for connection to safe control systems:
ÌUse a common power supply for the control system and the connected safety switches.
ÌA pulsed power supply must not be used for UB. 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 sufcient electrical current.
ÌAlways connect inputs FI1A and FI1B directly to a power supply unit or to outputs FO1A and FO1B of another EUCHNER
BR device (series connection). Pulsed signals must not be present at inputs FI1A and FI1B.
ÌThe safety outputs (FO1A and FO1B) 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 grids). 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 test-pulse duration of your safety switch, please refer to chapter 11.
Technical data on page 22.
A detailed example of connecting and setting the parameters of the control system is available for many devices at
www.euchner.com in the area Download » Applications » CES. The features of the respective device are dealt with there in
greater detail.

You will nd a detailed description of the signal functions in chapter 10. System status table CES‑I‑BR‑… on page 21.
LED Color
STATE green
DIA red
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 safety outputs and the monitoring output OD/C are switched off, i.e. the system is in the
safe state.
Tip!
It is recommended to perform the teach-in operation prior to mounting. Mark switches and actuators
that belong together in order to avoid confusion. For devices to be connected in series, we recommend
performing the teach-in operation separately for each device prior to series connection.
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 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 in.
ÌThe safety switch can be operated only with the last actuator taught in.
ÌThe number of teach-in operations is unlimited.
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 operating distance for less than 30s, it will not be acti-
vated 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. Apply operating voltage to the safety switch.
¨The green LED ashes quickly (approx. 5Hz)
A self-test is performed during this time (approx. 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. On switches that have not been taught in, teach-in
standby is unlimited.
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. After successful teach-in, the STATE and DIA LEDs ash alternately. The new
code has now been stored, and the old code is disabled. The teach-in operation takes approx. 30s.
3. Disconnect safety switch from the operating voltage for 3 seconds.
¨The switch is in normal operation after the self-test.

9.3. Functional check
WARNING
Danger of fatal injury as a result of faults in installation and functional check.
ÌBefore carrying out the functional check, make sure that there are no persons in the danger zone.
ÌObserve the valid accident prevention regulations.
9.3.1. Electrical function test
After installation and any fault, the safety function must be fully checked. Proceed as follows:
1. Switch on operating voltage.
¨The machine must not start automatically.
¨The safety switch carries out a self-test. The green STATE LED ashes for 5s at 5Hz. The green STATE LED then ashes
at regular intervals.
2. Close all guards.
¨The machine must not start automatically.
¨The green STATE LED illuminates continuously.
3. Enable operation in the control system.
4. Open the guard.
ÌThe machine must switch off and it must not be possible to start it as long as the guard is open.
ÌThe green STATE LED ashes at regular intervals.
Repeat steps 2-4 for each guard.
