2. Correct use
Safety switches series CES-I-BP 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
ÌENISO12100
ÌIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
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.
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 8).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 11. Technical data on page 18).
4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety regulations 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 operational 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. Diagnostic output OD/C
The device has a diagnostic output that can be used either as a door monitoring output or as a communication output to a
BR evaluation unit (e.g. ESM-CB). During starting, the device automatically detects whether it is connected to an input on a
BR evaluation unit. In this case the diagnostic output OD/C operates as a communication output OC.
6.1.1. Door monitoring output OD
The door monitoring output is switched on as soon as a valid actuator is detected in the operating distance.
6.1.2. Communication output OC
The communication output is used to exchange data with an evaluation unit for BR series connections. The switch delivers
process data determined cyclically. Acyclical data can also be sent by means of specically polling by the evaluation unit.
You will nd an overview of the communication data in chapter 8.8. Connection to a BR evaluation unit.
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‑BP‑… on page 17.

7. Mounting
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 mounting 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.
min. 50 mm

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 fastenings 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 connecting cable must be laid with protection in areas in which high-pressure cleaners are
used.

8. Electrical connection
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 connecting 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 output only 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 a connected evaluation unit 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.
