2. Correct use
Safety switches series CTM-L.-… are interlocking devices with guard locking solenoid (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:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed and
locked.
ÌThe guard locking must not be released until the dangerous machine function has ended.
ÌClosing 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 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:
ÌENISO13849-1
ÌENISO12100
ÌIEC62061
Correct use includes observing the relevant requirements for installation and operation, particularly based on the following
standards:
ÌENISO13849-1
ÌENISO14119
ÌEN60204-1
The safety switch is allowed to be operated only in conjunction with the intended EUCHNER actuator and the related connec-
tion 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 a BR switch chain is permitted only using devices intended for series connection in a BR
switch chain. Check this in the specications of the device in question.
Important!
ÌThe 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.
ÌIt 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 ENISO14119)
ÌSafety function (see chapter 6.5. Switching states on page 11):
- The safety outputs are switched off when guard locking is released (monitoring of the locking element).
- 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 (prevention of inadvertent locking posi-
tion (faulty closure protection)).1)
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 13. Technical data on page 33).
NOTICE
You can regard the complete BR device chain as one subsystem during calculation. The following
calculation method applies to the PFHDvalue:
#1
PFHD,1 PFHD,ext
BR-Device #1 ... n External Evaluation
(e.g. PLC)
PFHDges =∑ PFHD,k + PFHd,ext
n
k=1
#2
PFHD,2
#n
PFHD,n
Alternatively, the simplied method according to section 6.3 of EN 13849-1:2015 can be used for
calculation.
1) Limited prevention of inadvertent locking position (faulty closure protection) on Power Up.

3.1. Control of guard locking for variants with IMP/IMM connection
If the device is used as guard locking for personnel protection, the control of the guard locking must be regarded as a
safety function.
The safety level of guard locking control is determined by the device PFHDint. and by the external control (e.g. PFHDext. of
the standstill monitor), but cannot be higher than PLd.

Releasing guard locking
ÌSafety functions
- Guard locking remains activated until IMP requests releasing the guard locking.
The decisive criterion for a possible request to deactivate guard locking is a voltage of at least 5V between the inputs IMP
and 0V or between IMP and IMM.
The external control system must recognize and react to short circuits on these control signals. Fault exclusion, e.g. by
laying the cables with protection, can be considered as an alternative.
3.2. Control of guard locking via IO-Link communication
If the device is used as guard locking for personnel protection, the control of the guard locking must be regarded as a
safety function.
The device does not feature a safety characteristic for the control of the guard locking.

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 fulll personnel protection functions. Incorrect installation or tampering can lead to fatal injuries to personnel.
Check the safe function of the safeguard particularly
Ìafter any setup work
Ìafter the replacement of a system component
Ìafter an extended period without use
Ìafter every fault
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 fulll
a personnel protection function.
ÌSafety 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 bypass-
ing according to ENISO14119:2013, section 7.
ÌThe switching operation must be triggered only by actuators designated for this purpose.
ÌPrevent bypassing by means of replacement actuators (only for multicode evaluation). For this
purpose, restrict access to actuators and to keys for releases, for example.
ÌDamaged actuators can lead to limited prevention of inadvertent locking position (faulty closure
protection) when the machine is switched on. The guard locking function can no longer be ensured
if an actuator is broken. Opening the door will immediately turn off the safety outputs. Regularly
check the actuator for mechanical damage.
ÌMounting, 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.
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 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.
ÌDevices 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 assign-
ment ensures a particularly high level of protection against tampering. The system thus
possesses a high coding level.
ÌDevices with multicode evaluation: Unlike systems with unicode evaluation, on multi-
code devices a specic 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 evaluation). There
is no exact comparison of the actuator code with the taught-in code in the safety switch
(unicode evaluation). The system possesses a low coding level.
When the guard is closed, the actuator is moved into the safety switch. When the operat-
ing distances are reached, power is supplied to the actuator by the switch and data are
transferred.
The door position signal OD is set when a permissible code is detected. Guard locking is
activated automatically if no voltage is present at IMP. The safety outputs are switched on when guard locking is active.
The safety outputs are switched off and the guard locking signal OL is cleared when guard locking is released.
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).
6.1. Bistable guard locking
Guard locking of the switch functions according to the bistable principle. This means that guard locking is kept in its last
position if the power supply is interrupted or when the machine is switched off for servicing, for example. As a result, the
safety door is either constantly locked or it can be closed and opened as required without activating the guard locking. Guard
locking is released via control input IMP or via IO-Link communication. Also see chapter 6.4. Guard locking on page 10.
6.2. 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.
6.3. Monitoring outputs/status bits
Depending on version, the signals listed in the following are available as a status bit or on the monitoring output. The status
bits are evaluated via the BR/IO-Link Gateway. Please refer to the enclosed data sheet for further information.
6.3.1. Door position signal OD
The door position 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.
6.3.2. Diagnostic signal OI
The diagnostic signal is present if there is an error (switch-on condition as for DIA LED).
6.3.3. Guard locking signal OL
The guard locking signal is present if the guard locking is active.
6.3.4. Status signal OM
The status signal is present if the device’s safety outputs are switched.

6.3.5. 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.
6.3.6. Communication connection C
A monitoring output with the sufx 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 nd an overview of the communication data in chapter10.
Using communication data on page 26.
If no BR/IO-Link Gateway is connected, this output behaves like a monitoring output.
6.4. Guard locking
Important!
Malfunctions due to incorrect use.
ÌThe actuator must not be under tensile stress during release.
ÌVery strong jolts or vibration can cause the guard locking state to change unintentionally. This gen-
erally applies when the switch is electrically isolated.
- The switch must not be used as a mechanical end stop.
- In case of heavy doors, ensure that the impact energy is cushioned on closing.
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.
Important!
If the guard is open when the power supply is interrupted and is then closed, guard locking remains
released. This prevents people from being locked in unintentionally.
6.4.1. Guard locking on version CTM-LBI and control via control input IMP
(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.
6.4.2. Guard locking on version CTM-LBI and control via IO-Link communication
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: guard locking actuated by spring force and controlled by bitCL (bitCL=0).
Releasing guard locking: guard locking released by the device’s operating voltage and deactivated by bitCL (bitCL=1).
