2. Correct use

Safety switches series CTP-L.-… are interlocking devices with guard locking (type 4). Devices with unicode evaluation possess a high coding level; devices with multicode evaluation feature a low coding level.

In combination with a movable safety guard and the machine control, this safety component prevents the safety guard from being opened while a dangerous machine function is being performed.

This means:

Ì Starting commands that cause a dangerous machine function must become active only when the safety guard is closed and locked.

Ì The guard locking device must not be unlocked until the dangerous machine function has ended.

Ì Closing and locking a safety 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.

Devices from this series are also suitable for process protection.

Before the device is used, a risk assessment must be performed on the machine, e.g. in accordance with the following standards:

Ì EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design

Ì EN ISO 12100, Safety of machinery – General principles for design – Risk assessment and risk reduction

Ì IEC 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:

Ì EN ISO 13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design

Ì EN ISO 14119 (supersedes EN 1088), Safety of machinery – Interlocking devices associated with guards – Principles for design and selection

Ì EN 60204-1, Safety of machinery. Electrical equipment of machines. General requirements.

The safety switch is only allowed to be operated in conjunction with the intended EUCHNER 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 an AR switch chain is permitted only using devices intended for series connection in an AR 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 EN ISO 13849-2.

It 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 guard locking and the position of the safety guard (interlocking device with guard locking according to EN ISO 14119)

Safety function (see chapter

6.7. Switching states on page 9

-The safety outputs are switched off when guard locking is unlocked (monitoring of the locking device).

-The safety outputs are switched off when the safety guard is open (monitoring of the door position).

-Guard locking can be activated only when the actuator is located in the switch head (failsafe locking mechanism).

Ì Safety characteristics: Category, Performance Level, PFH d

(see chapter

13. Technical data on page 31

Control of guard locking

If the device is used as guard locking for personnel protection, control of guard locking must be regarded as a safety function.

The device does not feature a safety characteristic for control of guard locking, because the guard locking solenoid is completely disconnected from the outside (no control function within the device). It therefore does not contribute to the failure probability.

The safety level for the control of the guard locking is only defined by the external control (e. g. PFH d, ext.

monitor).

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 instructions

Safety switches provide personal protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.

Check the safe function of the safety 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 safety 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 perform a personal 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 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. EUCHNER cannot provide any warranty in relation to the readability of the CD for the storage period required. For this reason you should archive a printed copy of the operating instructions. You can download the operating instructions from www.EUCHNER.de.

6. Function

The device permits the locking of movable safety guards.

Transponder-coded actuator

The system consists of the following components: coded actuator (transponder) and switch.

Whether the complete actuator code of the device is taught in (unicode) or not

(multicode) depends on the respective version.

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 thereby possesses a high coding level.

Guard locking pin

Devices with multicode evaluation

: Unlike systems with unique code detection, on multicode devices a specific code is not polled 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 safety guard is closed, the actuator is moved into the safety switch. When the switch-on distance is reached, power is supplied to the actuator via the switch and data transfer takes place.

If a permissible code is detected, the safety outputs are switched on.

The safety outputs and the monitoring output (OL) are switched off when the safety 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 failures is detected at the latest on the next demand to close the safety outputs (e.g. on starting).

6.1. Guard lock monitoring

All versions feature two safe outputs for monitoring guard locking. The safety outputs (FO1A and FO1B) are switched off when guard locking is released.

6.2. Door monitoring output (OD)

All versions have a door monitoring output. The door monitoring output is switched on as soon as the actuator is inserted in the switch head (state: safety guard closed and not locked). The door monitoring output also remains switched on when guard locking is active.

6.3. Diagnostics output (OI)

The diagnostics output is switched on in the event of a fault (switch-on condition as for DIA LED).

6.4. Guard locking monitoring output (OL)

The guard locking monitoring output is switched on when guard locking is active.

6.5. Guard locking on version CTP-L1

(guard locking actuated by spring force and released by energy ON)

Activating guard locking:

close safety guard; no voltage at the solenoid.

Releasing guard locking:

apply voltage to the solenoid.

The spring-operated guard locking functions in accordance with the closed-circuit current principle. If voltage is interrupted at the solenoid, guard locking remains active and the safety guard cannot be opened directly.

Important!

If the safety guard is open when the power supply is interrupted and the guard is then closed, guard locking is activated. This can lead to persons being locked in unintentionally.

The actuator cannot be pulled out of the switch and the safety guard is locked as long as the guard locking pin is extended.

If voltage is applied to the guard locking solenoid, the guard locking pin is retracted and the actuator is released. The safety guard can be opened.

Operating instructions

Transponder-Coded Safety Switch CTP-AR

6.6. Guard locking on version CTP-L2

(guard locking actuated by energy ON and released by spring force)

Important!

Use as guard locking for personnel protection is possible only in special cases, after strict assessment of the accident risk (see EN ISO 14119:2013, section 5.7.1)!

Activating guard locking:

apply voltage to the solenoid.

Releasing guard locking:

disconnect voltage from the solenoid.

The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If voltage is interrupted at the solenoid, guard locking is released and the safety guard can be opened directly!

The safety guard can be opened as long as no voltage is applied to the guard locking solenoid.

If voltage is applied to the guard locking solenoid, the guard locking pin is held in the extended position and the safety guard is locked.

7.4. Wire front release (optional)

Release via a pull wire. Depending on the type of attachment, the wire front release can be used as emergency unlocking or escape release.

The following applies to non-latching wire front releases:

If the unlocking device is to be used for emergency unlocking, you must take one of the following measures (see EN ISO 14119:2013, section 5.7.5.3):

Ì Mount the unlocking device such that reset can only be undertaken with the aid of a tool.

Ì Alternatively, the reset can be undertaken at the control system level. E. g. by means of a plausibility check (status of the safety outputs does not match the guard locking control signal).

The emergency-unlocking specifications in chapter

7.2

Page 11

apply irrespective of this.

Important!

Ì The wire front release meets the requirements of Category B according to EN ISO 13849-1:2008.

Ì The correct function depends on the laying of the pull wire and on the attachment of the pull handle, and this is the responsibility of the plant manufacturer.

Ì The actuator must not be under tensile stress during manual release.

7.4.1. Laying wire front release

Important!

Ì Loss of the release function due to mounting errors, damage or wear.

Ì Check the release function every time after mounting.

Ì When routing the wire front release, ensure that it operates smoothly.

10. Electrical connection

The following connection options are available:

Ì Separate operation

Ì Series connection with Y-distributors from EUCHNER (only with M12 plug connector)

Ì Series connection, e.g. with wiring in the control cabinet.

Ì Operation on an AR evaluation unit.

WARNING

In case of an error, loss of the safety function through incorrect connection.

Ì To ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.

Ì Monitoring outputs must not be used as safety outputs.

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 The power supply for the evaluation electronics is electrically isolated from the power supply for the guard locking solenoid.

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 output lines FO1A/FO1B. A downstream control system must tolerate these test pulses, which may be up to 1 ms long on AR devices.

The test pulses on AR devices are also output when the safety outputs are switched off.

Depending on the inertia of the connected 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 +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 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 In order to avoid 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 60204-1:2006, section 4.4.2 (EMC).

CAUTION

Please pay attention to any interference fields in case of devices such as frequency converters or induction heating systems. Observe the EMC instructions in the manuals from the respective manufacturer.

Important!

If the device does not appear to function when operating voltage is applied (e.g. green STATE LED does not flash), the safety switch must be returned unopened to the manufacturer.

Figure 3: Circuit example with six CES-AR/CTP-L1-…

A safety relay is connected downstream which consumes 75 mA on each of the two safety inputs. This operates over the whole temperature range with a voltage of 19.2 V (corresponds to 24 V -20%).

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: 6 switches.

2. In column I

FO1A/FO1B

Here: 100 mA.

(possible output current per channel FO1A/FO1B), find a current greater than or equal to 75 mA.

It is then possible to determine the maximum cable length from the last switch (#6) to the control system from column l

. Here: a length of 50 m is permitted.

Result: The desired cable length l

1 chain l max

of 40 m is below the permitted value from the table. The overall length of the switch

of 140 m is less than the maximum value of 200 m.

The planned application is therefore functional in this form.

10.9. Connection of a single CTP-AR

If a single CTP-AR is used, connect the switch as shown in

Figure 4

. The monitoring outputs can be routed to a control system.

The switches can be reset via the RST input. To do this, a voltage of 24 V is applied to the RST input for at least 3 s. The

RST input must be connected to 0 V if it is not used.

WARNING

In case of an error, loss of the safety function through incorrect connection.

Ì To ensure safety, both safety outputs (FO1A and FO1B) must always be evaluated.

Important!

Ì The example shows only an excerpt that is relevant for connection of the CTP system. The example illustrated here does not show complete system planning. The user is responsible for safe integration in the overall system. Detailed application examples can be found at www.EUCHNER.de.

10.10. Connection of several CTP-AR in a switch chain

Important!

Ì An AR switch chain may contain a maximum of 20 safety switches.

de. Simply enter the order number of your switch in the search box. You will find 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 2 x M12. The series connection of the version with plug connector RC18 has similar behavior, but is realized using additional terminals in a control cabinet.

The switches in the version with plug connectors 2 x M12 are connected one after the other with the aid of pre-assembled connection cables and Y-distributors. If a safety guard 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 guard is open or on which switch a fault has occurred with this connection technology.

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 unit will switch to the fault state.

Always use the RST input in series connections. All switches in a chain can be reset at the same time with this reset input.

To do this, a voltage of 24 V must be applied to the RST input for at least 3 s. If input RST is not used in your application, it should be connected to 0 V.

Note the following on this aspect:

Ì A common signal must be used for all switches in the chain. This can be a changeover switch or the output of a control system. A button is not suitable because Reset must always be connected to GND during operation (see switch S11 in

Figure 5 on page 24

Ì Reset must always be performed simultaneously for all switches of the chain.

10.11. Notes on operation with safe control systems

Please observe the following requirements 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 supply voltage is connected to a terminal of a safe control system, this output must provide sufficient electrical current.

Ì Always connect inputs FI1A and FI1B directly to a power supply unit or to outputs FO1A and FO1B of another EUCHNER

AR device (series connection). Pulsed signals must not be present at inputs FI1A and FI1B.

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 curtains). 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 pulse duration of your safety switch, please refer to chapter

13. Tech‑ nical data on page 31

Ì The following applies for single-channel control of the guard locking:

The guard locking (IMM) and the control system must have the same ground.

Ì For dual-channel control of the solenoid voltage by safe outputs of a control system, the following points must be observed (see also

Figure 6 on page 26

-If possible, switch off the pulsing of the outputs in the control system.

-Pulses up to a length of max. 5 ms are tolerated.

A detailed example of connecting and setting the parameters of the control system is available for many devices at www.

11.2. 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 are switched off, i.e. the system is in the safe state.

The teach-in operation is fully automatic.

Tip!

Prior to switching on, close the safety 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 the teaching-in with series circuits and on large systems.

Important!

Ì The teach-in operation may be performed only if the device does not have any internal errors.

Ì Devices in the condition as supplied remain in teach-in standby state until you have successfully taught in the first actuator. Once taught in, switches remain in the teach-in standby state for approx. 3 min. after each switch on.

Ì The 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.

Ì The safety switch can only be operated with the last actuator taught-in.

Ì If the switch detects the actuator that was most recently taught when in teach-in standby state, this state is ended immediately and the switch changes to normal state.

Ì The actuator to be taught-in is not activated if it is within the operating distance for less than 30 s.

123041-03-07/15 (translation of the original operating instructions)

Operating instructions

Transponder-Coded Safety Switch CTP-AR

11.2.1. Teaching-in actuator

1. Establish teach-in standby:

-Devices in the condition as supplied: unlimited teach-in standby after switching on

-Switches already taught in: teach-in standby is available for approx. 3 min after switching on

Teach-in standby indication, STATE LED flashes 3x repeatedly

2. Insert the actuator during teach-in standby.

The automatic teach-in operation starts (duration approx. 30 s).

During the teach-in operation the STATE LED flashes (approx. 1 Hz).

Alternate flashing of the STATE and DIA LEDs acknowledges the successful teach-in operation.

Teach-in errors are indicated by the illumination of the red DIA LED and a flashing code on the green State LED (see

chapter

12. System status table on page 30

3. Switch off operating voltage UB (min. 3 s).

The code of the actuator that was just taught in is activated in the safety switch.

4. Switch on operating voltage UB.

The device operates normally.

11.2.2. Teach-in function with series connection, replacing and teaching in device

It is recommended not to teach in the actuators in the series connection but to teach them in one by one instead. Teach-in in a series connection works analogously to separate operation in principle. It is a prerequisite that the steps below are followed. Further steps might have to be observed for mixed switch chains (e. g. for chains with CES and CET). Observe the operating instructions for the other devices in the chain for this purpose.

Work on the wiring (e. g. during device replacement) should generally be performed in a de-energized state. On certain systems, it is nevertheless necessary to perform this work and subsequent teach-in during ongoing operation.

Input RST must be connected as shown in

Figure 5 on page 24

to permit this.

Proceed as follows:

1. Open the safety guard on which the switch or actuator is to be replaced.

2. Mount the new switch or actuator and prepare it for the teach-in operation (see chapter

11.2.1. Teaching‑in actuator on page 28

3. Close all safety guards in the chain and activate guard locking.

4. Actuate the reset for at least 3 s (24 V on RST).

On the safety switch that is positioned at a new actuator, the green LED flashes at approx. 1 Hz and the actuator is taught-in. This takes approx. 30 s. Do not switch off during this time and do not actuate reset! The teach-in operation is complete when the STATE and DIA LEDs flash alternately.

5. Actuate the reset for at least 3 s (24 V on RST).

The system restarts and then continues to function in normal operation.

11.3. Functional check

WARNING

Danger of fatal injury as a result of faults in installation and functional check.

Before carrying out the functional check, make sure that there are no persons in the danger area.

Ì Observe the valid accident prevention regulations.

11.3.1. Mechanical function test

The actuator must slide easily into the actuating head. Close the safety guard several times to check the function. For devices with mechanical unlocking device (emergency unlocking or escape release), the correct function of the mechanical unlocking device must be checked as well.

11.3.2. 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 flashes for 10 s at 5 Hz. The green STATE LED then flashes at regular intervals.

2. Close all safety guards. Guard locking by solenoid force: activate guard locking.

The machine must not start automatically. It must not be possible to open the safety guard.

The green STATE LED illuminates continuously.

3. Enable operation in the control system.

It must not be possible to deactivate the guard locking as long as operation is enabled.

4. Disable operation in the control system and deactivate guard locking.

The safety guard must remain locked until there is no longer any risk of injury.

It must not be possible to start the machine as long as the guard locking is deactivated.

Repeat steps 2 - 4 for each safety guard.

13.1.1. Typical system times

Please refer to the technical data for the exact values.

Ready delay

: After switching on, the unit carries out a self-test. The system is ready for operation only after this time.

Switch-off time of safety outputs

: The max. reaction time t on to the moment when the safety outputs switch on.

is the time from the moment when the safety guard is locked

Simultaneity monitoring, safety inputs FI1A/FI1B

: If the safety inputs have different switching states for longer than a specific time, the safety outputs (FO1A and FO1B) will be switched off. The device switches to fault state.

Risk time according to EN 60947-5-3

: If an actuator moves outside the operating distance, 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: t r

= t r, e

+ (n x t l

) t r

= Total risk time t r, e

= Risk time, single device (see technical data) t l

= Risk time delay 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 assume the same signal state at the latest 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, please contact our support organization.

The test pulses are also output when the safety outputs are switched off.
