2. Correct use
Safety switches series CTS-C2-BP/BR-CC-FLX are interlocking devices with guard
locking solenoid (type 4) for process protection without safe guard locking
monitoring. The device complies with the requirements according to EN IEC
60947-5-3.
The device can be configured with the aid of a function actuators. Depending
on the function actuator taught-in, the monitoring of the guard locking for
process protection is permanently active or available as an additional option
and the evaluation of the actuator code has a high or low coding level.

If monitoring of the guard locking for process protection is active, the
following applies:
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 or the guard locking is unlocked.
This means: Ì Starting commands that cause a dangerous machine function must
become active only when the guard is closed
and locked. Ì Opening the guard must trigger a stop command. Ì Closing and
locking 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.
If monitoring of the guard locking for process protection is optional, the
following applies:
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 must trigger
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 EN ISO 12100 or relevant C-standards.
If the evaluation of the actuator code has a high coding level, the following
applies: Ì 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.
If the evaluation of the actuator code has a low coding level, the following
applies:
EN Ì With the low coding level a specific code is not requested but instead it
is only checked whether the actuator
is of a type that can be detected by the system. There is no exact comparison
of the actuator code with the taught-in code in the safety switch. The system
possesses a low coding level.

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 fulfill personnel protection functions. Incorrect installation
or tampering can lead to fatal injuries to personnel.
Check the safe function of the safeguard 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 Ì after any reconfiguration of the device
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 fulfill a personnel protection function. Ì Safety components
must not be bypassed, turned away, removed or otherwise rendered ineffective.
On this topic pay attention in particular to the measures for reducing the
possibility of bypassing according to EN ISO 14119:2013, 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 low
coding level evaluation). For this purpose, restrict access to actuators and
to keys for releases, for example. Ì Make sure the guard cannot be closed
unintentionally, e.g. during servicing. For this purpose, a lockout bar can be
used, for instance. 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 operational safety
and accident prevention.
NOTICE
Risk of damage Ì The guard locking function can no longer be ensured if an
actuator is broken. Opening the door will
immediately switch off the safety outputs. Regularly check the actuator for
mechanical damage.
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. You can download the operating instructions from

6. Function
The device monitors the position of movable guards.
The system consists of the following components: coded actuator (transponder)
and switch.
The coding level of the system depends on the configuration of the device (see
chapter 13.1. Configuring device and teaching-in actuator for the first time
on page 31).
When the guard is closed, the actuator is moved into the safety switch. When
the operating distances are reached, power is supplied to the actuator by the
switch and data are transferred.
Switch
Coded actuator
The door position 1 signal OD is set if a permissible code is detected. Guard
locking is activated automatically if power is present at the guard locking
solenoid. The switching conditions for the safety outputs are dependent on the
configuration of the monitoring of the guard locking for process protection
(see chapter 6.4. Switching states on page 11).
If there is a fault in the safety switch, the safety outputs are switched off
and the DIA LED illuminates or flashes red (see chapter 15.3. Error messages
on page 36). The occurrence of faults is detected at the latest on the next
demand to close the safety outputs (e.g. on starting).
6.1. Monitoring of the guard locking for process protection
The device is configured with the aid of the function actuator. Depending on
the function actuator taught-in, the monitoring of the guard locking for
process protection is permanently active or available as an additional option.
Further information about the possible settings is available in the chapter
13.1. Configuring device and teaching-in actuator for the first time on page
31.
If monitoring of the guard locking for process protection is active, the
following applies:
All versions feature two safe outputs for monitoring the guard locking for
process protection. The safety outputs FO1A and FO1B are switched off and the
guard locking signal OL is cleared when guard locking is released.
If monitoring of the guard locking for process protection is optional, the
following applies:
All versions feature two safe outputs for monitoring the door position as well
as the status signal OL for monitoring the guard locking for process
protection; this signal can be evaluated optionally. The safety outputs FO1A
and FO1B are switched off and the door position 1 signal OD is cleared when
the guard is opened.
The following switching conditions apply to the safety outputs FO1A and FO1B:
No fault in the device Guard closed Guard locking active

Operating Instructions Transponder-Coded Safety Switch CTS-C2-BP/BR-CC-FLX
6.2.2. Door position 1 signal OD The door position 1 signal is sent as soon as
the actuator is inserted into the switch head (state: guard closed and not
locked). The signal is also present if the guard locking is active.
6.2.3. Door position 2 signal OT The door position 2 signal is present if the
actuator is completely inserted in the switch head and the guard locking can
be activated. In normal ambient conditions, the signal OT is sent after the
signal OD as an additional door monitoring contact. The signal is also present
if the guard locking is active (see chapter 6.4. Switching states on page 11).
6.2.4. Diagnostic signal OI The diagnostic signal is present if there is an
error (switch-on condition as for DIA LED).
6.2.5. Escape release signal OER The escape release signal is present if the
device has been released manually (see chapter 7. Manual release on page 12).
The signal is reset if the guard locking is re-activated or a reset has been
undertaken.
6.2.6. Status signal OM The status signal is present if the device’s safety
outputs are switched.
6.2.7. Locking element signal OLS The locking element signal is present if the
locking element is stuck and it is therefore not possible to
activate/deactivate guard locking. The signal is reset as soon as the actuator
is no longer under tensile stress or the locking element is no longer jammed.
6.2.8. Communication connection C A monitoring output with the suffix C has
the additional function of providing a communication connection to a BR/IO-
Link Gateway. The switch delivers cyclical and acyclical data. You will find
an overview of the communication data in chapter 12. Using communication data
on page 28. If no BR/IO-Link Gateway is connected, this output behaves like a
monitoring output.
6.3. Guard locking for process protection
(guard locking actuated by power-ON and released by spring force)
Important! Malfunctions due to incorrect use. Ì The actuator must not be under
tensile stress during release. Ì The guard locking is only activated if, in
addition to the power at the guard locking solenoid, the
operating voltage is applied to the device.
The magnetically actuated guard locking operates according to the open-circuit
current principle. If the voltage is interrupted at the solenoid, the guard
locking is released and the guard can be opened directly. The guard can be
opened as long as no power is applied to the guard locking solenoid or there
is no operating voltage at the device. If power is applied to the guard
locking solenoid and the actuator is completely inserted, the guard locking
pin is held in the extended position and the guard is locked. Activating guard
locking: close guard; apply power to the solenoid and operating voltage.
Releasing guard locking: disconnect power from the solenoid or operating
voltage.

9. Electrical connection
The following connection options are available: Ì Separate operation Ì Series
connection with wiring in the control cabinet Ì Series connection with
Y-distributors Ì Connection without IO-Link communication Ì Connection with
IO-Link communication
WARNING
In the event of a fault, 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 connecting
cables with protection to prevent 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 300 µs. Depending on the inertia of the downstream device (control system,
relay, etc.), this can lead to short switching processes. The test pulses are
output only with the safety outputs switched off during device start. Ì The
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. 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 insulation measures
(SELV). 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 prevent EMC interference,
the physical environmental and operating conditions at the installation site
of the device must comply with the requirements according to the standard EN
60204-1 (EMC). Ì Pay attention to any interference fields from devices such as
frequency converters or induction heating systems. Observe the EMC
instructions in the manuals from the respective manufacturer. Ì If the
solenoid is operated with a frequency of more than 0.2 Hz, the device may
react with a delay. Ì In devices with IMP/IMM inputs, the power supply for the
evaluation electronics is separate from the power supply for the guard locking
solenoid. If different power supplies are used, they must have the same
reference potential. Ì For device variants with two connecting cables, both
cables must be laid in the same cable duct.
Important!
EN If the device does not appear to function when the operating voltage is
applied (e.g. STATE LED does
not flash), the safety switch must be returned to the manufacturer.

Notes about
Important!
Ì This device is intended to be used with a Class 2 power source in accordance
to UL1310. As an alternative an LV/C (Limited Voltage/Current) power source
with the following properties can be used: This device shall be used with a
suitable isolating source in conjunction with a fuse in accordance to UL248.
The fuse shall be rated max. 3.3 A and be installed in the max. 30 V DC power
supply to the device in order to limit the available current to comply with
the UL requirements. Please note possibly lower connection ratings for your
device (refer to the technical data).
Ì For use and application as per the requirements of UL 1) a connecting cable
listed under the UL category code CYJV/7, min. 24 AWG, min. 80 °C, must be
used.
- Note on the scope of the UL approval: the devices have been tested as per the requirements of UL508 and CSA/ C22.2 no. 14 (protection against electric shock and fire).
9.2. Safety in case of faults
Ì The operating voltage UB and the solenoid operating voltage UIMP are reverse
polarity protected. Ì The safety outputs FO1A/FO1B are short circuit-proof. Ì
A short circuit between the safety outputs is detected on starting or when the
safety outputs are activated by the device. Ì A short circuit in the cable can
be excluded by laying the cable with protection.
9.3. Fuse protection for power supply
The power supply must be provided with fuse protection depending on the number
of switches and the current required for the outputs. The following rules
apply:
Max. current consumption of an individual switch Imax Imax UB = IUB_1 + IFO1A+FO1B + IOX1 + IOX2
IUB_1 = Switch operating current (max. 50 mA)
IOX
= Load current of monitoring output (max. 20 mA per monitoring output)
IFO1A+FO1B = Load current of safety outputs FO1A + FO1B (2 x max. 80 mA)
Imax IMP = Solenoid operating current (max. 500 mA)
Max. current consumption of a switch chain Imax UB Imax UB = IFO1A+FO1B + n x (IUB_2 + IOX1 + IOX2)
n
= Number of connected switches
IUB_2 = Switch operating current (max. 80 mA)
Important! If there are further monitoring outputs, their load current must be taken into account.

9.7. Notes on operation with safe control systems
Observe the following guidelines for connection to safe control systems: Ì Use
a common power supply for the control system and the connected safety
switches. Ì A pulsed power supply must not be used for UB. Tap the supply
voltage directly from the power supply unit. If the power
supply is connected to a terminal of a safe control system, this output must
provide sufficient electrical current. Ì The 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, refer to chapter 16. Technical data on page 38. Ì With series
connection: always connect inputs FI1A and FI1B directly to a power supply
unit or to outputs FO1A and FO1B of another EUCHNER BR device. Pulsed signals
must not be present at inputs FI1A and FI1B. 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 Downloads/Applications/CTS. The features of
the respective device are dealt with there in greater detail.
9.8. Connection without and with IO-Link communication
9.8.1. Connection without IO-Link communication Only the safety and monitoring
outputs are switched with this connection method. With a series connection,
the safety signals are looped through from device to device.
9.8.2. Connection with IO-Link communication If, in addition to the safety
function, detailed monitoring and diagnostic data are to be processed, a BR
/IO-Link Gateway is required. To poll the communication data from the
connected device, communication connection C is routed to the BR/ IO-Link
Gateway. You will find further information in the operating instructions for
your BR/IO-Link Gateway.

Connector assignment of Y-distributor for series connection with IO-Link
communication on page 27.
11.1. Series connection with wiring in the control cabinet
The series connection can be realized via additional terminals in a control
cabinet.
Important!
In case of series connection with IO-Link communication: Ì 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. Ì If the connections are
interchanged (e.g. FO1A to FI1B), the downstream device will enter the fault
state.
11.2. Series connection with Y-distributors
The series connection is shown here based on the example of the version with
plug connector M12. The switches are connected one behind the other with the
aid of pre-assembled connecting 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.

12. Using communication data
A BR/IO-Link Gateway is required to use the device’s communication data and
forward them to a higher-level bus system. The following devices are suitable:
Ì GWY-CB-1-BR-IO (BR/IO-Link Gateway) Ì ESM-CB (safety relay with integrated
BR/IO-Link Gateway)
12.1. Connection to a BR/IO-Link Gateway GWY-CB
The Gateway is an IO-Link device. Communication via IO-Link offers cyclical
(process data) and acyclical (device data and events) data exchange (see
chapter 12.3. Overview of the communication data on page 29). The
communication connection C on the device allows the diagnostic line to be
connected to the Gateway. The Ox/C connection represents a non-safety-related
communication channel between the Gateway and the connected devices. IO-Link
communication can be used for the following functions as well: Ì Reset for
acknowledging error messages
You will find further information in the operating instructions for your BR
/IO-Link Gateway.
12.2. Connection to a safety relay ESM-CB
The safety relay ESM-CB features an integrated BR/IO-Link Gateway. In addition
to functioning as an IO-Link device (see chapter 12.1. Connection to a BR/IO-
Link Gateway GWY-CB on page 28), the device can be used for connecting two
monitored single- or dual-channel sensor circuits. The sensor circuits
evaluate various signaling devices: Ì Sensor circuit S1 with short circuit
detection; suitable for single- or dual-channel safety sensors Ì Sensor
circuit S2, suitable for OSSD signals; short circuit detection by signaling
device
When at least one sensor circuit is interrupted, the safety relay initiates
the safe state. Different relay starting behaviors and various monitoring
functions are possible. The device’s safety outputs FO1A and FO1B are routed
to the OSSD inputs of the safety relay. The Ox/C connection of the device
allows the diagnostic line to be connected to the Gateway. You will find
further information in the operating instructions for your safety relay with
integrated BR/IO-Link Gateway.

13. Setup
13.1. Configuring device and teaching-in actuator for the first time
The device must be configured and the actuator must be allocated to the safety
switch before the system forms a functional unit. During configuration, with
the aid of a function actuator, the monitoring of the guard locking for
process protection is specified as permanently active or available as an
additional option. The coding level is also defined. As such the selection of
the actuator determines the function of the device.
Configuration and the teach-in operation occur simultaneously in the delivery
state or after a factory reset.

WARNING
Danger to life due to improper use Ì During the initial configuration or
reconfiguration after a factory reset, ensure that all risk assessment
measures for the selected function are performed.
Important!
Ì If the actuator to be taught-in is in the actuating range for less than 30
s, the device will not be configured and the actuator will not be taught-in.
Prerequisite: Ì The device is in the delivery state. A factory reset must be
performed before a preconfigured device can be reconfigured
(see chapter 14. Factory reset on page 34). Ì The device is isolated from the
operating voltage.
1. Apply operating voltage. ¨ The STATE LED flashes white quickly. The device is carrying out a self-test. ¨ The STATE LED illuminates white. The device is in unlimited teach-in standby. 2. Insert an actuator. ¨ The teach-in operation begins. The STATE LED flashes alternately white/violet slowly. ¨ The teach-in operation ends after approx. 30 s. The STATE LED flashes alternately green/blue quickly (approx. 3 Hz). 3. Switch off operating voltage for at least 3 s. ¨ The code of the actuator taught-in is activated in the safety switch. The actuator is valid. 4. Switch on operating voltage. ¨ The device operates normally.

13.2. Teaching-in new actuator (only for evaluation of the actuator with a
high coding level)
Tip!
Prior to switching on the operating voltage, close the guard on which the
actuator to be taught-in is installed. The teach-in operation starts
immediately after switching on. This feature simplifies above all teach-in
with series connections and on large installations.
Important! Ì During a teach-in operation, the safety outputs are switched off,
i.e. the system is in the safe state. Ì The 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. Ì The safety switch can be
operated only with the last actuator taught-in. Ì The number of teach-in
operations is unlimited. Ì If the actuator to be taught-in is within the
actuating range for less than 30 s, it will not be activated and the most
recently taught-in actuator will remain saved. The device indicates an error
(see chapter 15.3. Error messages on page 36).
Prerequisite: Ì The device is isolated from the operating voltage.
1. Make sure there is no actuator in the actuating range. 2. Apply operating
voltage. ¨ The STATE LED flashes white quickly (5 Hz). The device is carrying
out a self-test. ¨ The device is in teach-in standby for up to 3 minutes. The
STATE LED flashes green. 4. Insert an actuator that has not been taught-in. ¨
The teach-in operation begins. The STATE LED flashes alternately white/violet
slowly. ¨ The teach-in operation ends after approx. 30 s. The STATE LED
flashes alternately green/blue quickly (approx. 3 Hz). 5. Switch off operating
voltage for at least 3 s. ¨ The code of the new actuator taught-in is
activated in the safety switch. The actuator is valid. 6. Switch on operating
voltage. ¨ The device operates normally.

13.3. Functional check
WARNING
Danger of fatal injury as a result of faults in installation and functional
check. Ì Before carrying out the functional check, make sure that there are no
persons in the danger zone. Ì Observe the valid accident prevention
regulations.
13.3.1. Mechanical function test The actuator must slide easily into the switch. Close the guard several times to check the function.
13.3.2. Electrical function test After installation and after any fault, the
safety function must be fully checked. Proceed as follows:
If monitoring of the guard locking for process protection is active: 1. Switch
on operating voltage. ¨ The machine must not start automatically. ¨ The safety
switch carries out a self-test. The STATE LED then flashes green slowly. 2.
Close all guards. In case of guard locking by solenoid force: activate guard
locking. ¨ The machine must not start automatically. It must not be possible
to open the guard. ¨ The STATE LED illuminates green, the LOCK LED illuminates
orange. 3. Enable operation in the control system. ¨ It must not be possible
to deactivate guard locking as long as operation is enabled. 4. Unlock guard
locking if necessary and open guard. ¨ The machine must switch off and it must
not be possible to start it as long as the guard is open. Repeat steps 2 – 4
for each guard.
If monitoring of the guard locking for process protection is optional:
1. Switch on operating voltage.
¨ The machine must not start automatically.
¨ The safety switch carries out a self-test. The STATE LED then flashes green slowly.
2. Close all guards. As soon as the actuator is inserted into the switch, the safety outputs are switched on independent of the state of the guard locking.
¨ The machine must not start automatically.
¨ The STATE LED illuminates green. In addition, depending on the state of the guard locking, the LOCK LED illuminates orange permanently or with a short interruption.
3. Enable operation in the control system.
4. Unlock guard locking if necessary and open guard.
¨ The machine must switch off and it must not be possible to start it as long as the guard is open. Repeat steps 2 – 4 for each guard.

16.1.1. Typical system times Refer to the technical data for the exact values.
Ready delay: After switching on, the device carries out a self-test. The
system is ready for operation only after this time. Turn-on time of safety
outputs: The max. reaction time ton is the time from the moment when the guard
is locked to the moment when the safety outputs switch on. Risk time according
to EN 60947-5-3: The risk time is the maximum time until at least one of the
safety outputs FO1A or FO1B switches off safely when the actuator is removed
from the actuating range. This also applies if an internal or external fault
occurs at this moment.
For optional guard locking monitoring for process protection the following
applies: if an actuator moves outside the actuating range, the safety outputs
FO1A and FO1B are switched off after the risk time at the latest. If several
devices are operated in a series connection, the risk time of the overall
device chain will increase with each device added. Use the following
calculation formula: tr = tr, e + (n x tl) tr = Total risk time tr, e = Risk
time for single device (see technical data) tl = Risk time extension per
device n = Number of additional devices (total number -1) Discrepancy time:
The safety outputs FO1A and FO1B switch with a slight delay in relation to
each other. They have the same signal state no later than after the
discrepancy time. Test pulses at the safety outputs: The device generates its
own test pulses on the safety outputs FO1A and FO1B. A downstream control
system must tolerate these test pulses. This can usually be set up in the
control systems by parameter assignment. If parameter assignment is not
possible for your control system or if shorter test pulses are required,
contact our support organization. The test pulses are output only if the
safety outputs are switched on.
