2. Correct use
Safety switches series CTP-L.-… are interlocking devices with guard locking (type 4). The device complies with the requirements according to ENIEC60947-5-3. Devices with unicode evaluation possess a high coding level, devices with multicode
evaluation possess a low coding level.
In combination with a movable guard and the machine control, this safety component prevents the 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 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 guard must not cause automatic starting of a dangerous machine function. A separate start com-
mand must be issued. For exceptions, refer to ENISO12100 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 ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO12100, Safety of machinery – General principles for design – Risk assessment and risk reduction
Ì IEC62061, 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 ENISO13849-1, Safety of machinery – Safety-related parts of control systems – Part 1: General principles for design
Ì ENISO14119, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì EN60204-1, Safety of machinery – Electrical equipment of machines – Part 1: General requirements
The safety switch is allowed to be operated only in conjunction with the intended EUCHNER actuator 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!
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 ENISO13849-2.
Ì 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 guard (interlocking device with guard locking according
to ENISO14119)
Ì Safety function (see chapter 6.6. Switching states on page 9):
- The safety outputs are switched off when guard locking is released (monitoring of the locking device).
- The safety outputs are switched off when the 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

4. Exclusion of liability and warranty
In case of failure to comply with the conditions for correct use stated above, or if the safety instructions are not followed,
or if any servicing is not performed as required, liability will be excluded and the warranty void.
5. General safety precautions
Safety switches fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the 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 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 personnel protection function.
Ì Safety 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 bypassing according to ENISO14119:2013, 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.com.

6. Function
The device permits the locking of movable guards.
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.
Ì 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 thus possesses a high coding level.
Transponder-coded
actuator
Guard locking pin
Ì Devices with multicode evaluation: Unlike systems with unique code
detection, on multicode devices a specic 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 into 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 and the monitoring output (OL) are switched off when the guard is unlocked.
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).
The switch has, in addition to the mechanical/electromagnetic guard locking, xing for the guard locking pin. The guard
locking pin is held in its current position if the operating voltage is not present. The guard locking pin can be moved only
by applying the operating voltage.
If the guard locking pin is extended and the guard is still open when the power supply is interrupted, the guard locking pin
will be pushed down and held in this position the next time the door is closed.
In case of interruption of the power supply (operating voltage) for the switch or if the machine is switched off for servicing,
for example, the guard locking pin is held in its last position. As a result the safety door is either permanently locked or it
can be closed and opened as often as required without the guard locking pin locking.
6.1. Guard locking 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)
The door monitoring output is switched on as soon as the actuator is inserted in the switch head (state: 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-LBI
(Guard locking actuated by spring force and released by power-ON)
Activating guard locking: close guard; no voltage at control input IMP
Releasing guard locking: apply voltage to control input IMP.
The spring-operated guard locking functions in accordance with the closed-circuit current principle. If the voltage is interrupted
at the solenoid, the guard locking remains active and the guard cannot be opened directly.
If the guard is opened when the power supply is interrupted and is then closed, the guard locking pin will be pushed down
and held in this position. This prevents people from being locked in unintentionally.
6.6. Switching states
The detailed switching states for your switch can be found in the system status table. All safety outputs, monitoring outputs
and display LEDs are described there.

7.4. Wire front release
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 release is to be used as emergency unlocking, one of the following measures must be
taken (see EN ISO 14119:2013, section 5.7.5.3):
Ì Install the release so that it can be reset only 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 activation
signal).
The emergency-unlocking specications in chapter 7.2 on Page 11 apply irrespective of
this information.
Important!
Ì The wire front release meets the requirements of CategoryB accord-
ing to ENISO13849-1:2015.

10. Electrical connection
WARNING
If there is a mistake, loss of the safety function due to 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.
Ì 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 device generates its own test pulses on the output lines FO1A/FO1B. A downstream control
system must tolerate these test pulses, which may have a length of up to 0.35ms.
Depending on the inertia of the downstream 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 +24V 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 To 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
EN60204-1:2006, section 4.4.2 (EMC).
Please 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 manufacturer.
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.
10.1. Notes about

10.6. Connection CTP-AP
Connect the device as shown in Figure 3. The monitoring outputs can be routed to a control system.
On devices with RST input the following applies: The switches can be reset via the RST input. To do this, a voltage of
24V is applied to the RST input for at least 3s. The RST input must be connected to 0V if it is not used.
WARNING
If there is a mistake, 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 The example shows only an excerpt that is relevant for connection of the CTP system. The exam-
ple 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.

10.7. 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 The device does not tolerate voltage interruptions at 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 sufcient 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 pulse duration of your safety switch, please refer to chapter 13. Tech‑
nical data on page 23.
Ì The following applies to single-channel control of 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 ob-
served (see also Figure 4 on page 19):
- 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.euchner.com in Downloads » Applications » CTP. The features of the respective device are dealt with there in greater
detail.

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. The number of possible teach-in operations is unlimited.
Tip!
Prior to switching on, close the guard on which the actuator to be taught in is installed. The teach-in
operation starts immediately after switching on. This feature simplies above all teach-in with series
circuits and on large installations.
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 rst actuator. Once taught in, switches remain in the teach-in standby state for approx. 3min. 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 be operated only with the last actuator taught in.
Ì If the switch detects the actuator that was most recently taught when in the 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 30s.
11.2.1. Actuator teach-in
1. Establish teach-in standby:
- Devices in the condition as supplied: unlimited teach-in standby after switching on
- Switch already taught in: teach-in standby is available for approx. 3 min after switching on
¨ Teach-in standby indication, STATE LED ashes 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 ashes (approx. 1Hz).
Alternate ashing 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 ashing code on the green State LED (see
chapter 12. System status table on page 22).
3. Switch off operating voltage UB (min. 3s).

¨ 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.
11.3. 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 applicable accident prevention regulations.
11.3.1. Mechanical function test
The actuator must slide easily into the actuating head. Close the guard several times to check the function. For devices with
mechanical release (emergency unlocking or escape release), the correct function of the release 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 then ashes at regular intervals.
2. Close all guards. Guard locking by solenoid force: activate guard locking.
¨ The machine must not start automatically. It must not be possible to open the guard.
¨ The green STATE LED and the yellow LOCK LED are illuminated continuously.
3. Enable operation in the control system.
¨ It must not be possible to deactivate guard locking as long as operation is enabled.
4. Disable operation in the control system and deactivate guard locking.
¨ The 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 guard.

13.1.1. Typical system times
Please 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.
Switch-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: If an actuator moves outside the operating distance, the safety outputs (FO1A
and FO1B) are switched off after the risk time at the latest.
Discrepancy time: The safety outputs (FO1A and FO1B) switch with a slight time offset. 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, please contact our support organization.
The test pulses are output only if the safety outputs are switched on.
