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 www.euchner.com.

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.

CAUTION
Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise rendered ineffective. Ì Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for bypassing
an interlocking device.
NOTICE
Risk of damage to equipment and malfunctions as a result of incorrect installation. Ì Safety switches and actuators must not be used as an end stop. Ì Observe EN ISO 14119:2014, sections 5.2 and 5.3, for information about mounting the safety switch
and the actuator. The following specifications must be observed: – Mounting with screws of property class 8.8 or higher. – The minimum screw diameter is 5 mm. – Secure the fixing material against loosening (e.g. by means of medium- strength positive screw
locking). Ì Protect the switch against damage, as well as against penetrating foreign objects such as swarf,
sand and blasting shot, etc. Ì Observe the min. door radii (see chapter 16.4.1. Dimension drawing for actuatorA-FLX-D-0.-… on page
42). Ì Observe the maximum permissible inclination angles between switch and actuator (see Fig. 4). Ì Observe the tightening torque for fastening the switch and the actuator (see Fig. 3):
– Actuator: 6 Nm – Switch head: 6 Nm – Switch housing: 3 Nm Ì The side of the switch in contact and the rear of the actuator must lie fully on the mounting surface. Ì Actuator and safety switch must be mounted such that the actuator is perpendicularly and completely inserted into the switch when the guard is closed (seeFig. 2). The guard locking function is not assured if installation is incorrect.
If monitoring of the guard locking for process protection is optional, the following applies:

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.

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.

1. 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.

WARNING
In the event of a fault, loss of the safety function due to incorrect connection. Ì To ensure safety, both safety outputs FO1A and FO1B must always be evaluated.
Important!
Ì A BR chain may contain a maximum of 20 safety switches. Ì The BR chain is not permitted to be changed during operation. Ì The example shows only an excerpt that is relevant for the connection of the CTS system. The
example illustrated here does not show complete system planning. The user is responsible for safe integration into the overall system. Detailed application examples can be found at www.euchner.com. Simply enter the order number of your switch in the search box. You will find all available connection examples for the device in Downloads. Ì Make sure you use the correct Y-distributors. See chapter 11.2.3. Connector assignment of Y-distributor for series connection without IO-Link communication on page 25 and chapter 11.2.4. 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.

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.

Operating Instructions Transponder-Coded Safety Switch CTS-C2-BP/BR-CC-FLX
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.
