2. Correct use
Safety switches series CTP-L.-… are interlocking devices with guard locking (type 4). The device complies with the requirements according to EN IEC 60947-5-3. 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 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, Safety of machinery – Interlocking devices associated with guards – Principles for design and selection
Ì EN 60204-1, 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.

6. Function
The device permits the locking of movable guards.
Transponder-coded actuator
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.
Guard locking pin
Ì Devices with multicode evaluation : Unlike systems with unique code detection, on multicode devices 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 (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, fixing 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.

Operating Instructions
Transponder-Coded Safety Switch CTP-LBI-AP
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.

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
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 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 0.35 ms.
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 +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 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).
Please 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.
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.

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 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
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 observed (see also
):
-If possible, switch off the pulsing of the outputs in the control system.
-Pulses up to a length of max. 5 ms are tolerated.

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 simplifies 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 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 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 30 s.
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 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 22 ).
3. Switch off operating voltage UB (min. 3 s).

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
Ì Before carrying out the functional check, make sure that there are no persons in the danger zone.
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 flashes 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 output s: The max. reaction time t on the moment when the safety outputs switch on.
is the time from the moment when the guard is locked to
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.
