2. Correct use
Safety switches series CTM-…-AS.. are operated as slaves on the safety bus AS-Interface Safety at Work and function
as interlocking devices with Guard Locking for Process Protection (type4) without guard locking monitoring. The device
complies with the requirements according to EN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 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:
ÌStarting commands that cause a dangerous machine function must become active only when the guard is closed.
ÌOpening the guard triggers a stop command.
ÌClosing 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.
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.
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 the guard position
(interlocking device according to ENISO14119)
ÌSafety function (see chapter 6.2. Switching states on page 8):
- When the guard is open, no valid code sequence is sent (monitoring of the door position).
ÌSafety characteristics: category, Performance Level, PFHD(see chapter 12. Technical data on page 16).
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 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.
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 pur-
pose, 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 cause the zero sequence to be sent. 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 monitors the position 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 assignment
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 detection). 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 operating
distances are reached, power is supplied to the actuator by the switch and data transfer
begins.
If the guard is closed and the code is permissible, each CTM-AS transmits a switch-specic, unique safety code sequence
with 8x4 bits via the AS-Interface bus.
The zero sequence is transmitted via the AS-Interface bus when the guard is opened.
In the event of a fault in the safety switch, the zero sequence is transmitted via the AS-Interface bus and the LOCK/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. Guard locking on version CTM-I2
(guard locking actuated by power-ON and released by spring force)
Activating guard locking: Close the guard, apply auxiliary power to the solenoid and set AS-Interface output bit D0.
Releasing guard locking: No auxiliary power at the solenoid and/or clear AS-Interface output bit D0.
The magnetically actuated guard locking operates in accordance with the open-circuit current principle. If the solenoid is
not controlled (D0=0) or if auxiliary power is switched off, guard locking is released and the guard can be opened directly!
If the solenoid is controlled via the ASi bus (D0=1) and auxiliary power is applied to the solenoid, guard locking is activated
and the guard is locked.

7. Manual release
Important!
ÌAll release functions latch when the device is electrically isolated.
ÌGuard locking remains released when the release function is reset.
Some situations require the guard locking to be released manually (e.g. malfunctions or an emergency). A function test
should be performed after release.
More information on this topic can be found in the standard ENISO14119:2013, section 5.7.5.1. The device can feature
the following release functions:
7.1. Auxiliary release
In the event of malfunctions, the guard locking can be released with the auxiliary release irre-
spective of the state of the solenoid.
Important!
ÌThe actuator must not be under tensile stress during manual release.
ÌLoss of the release function due to mounting errors or damage during
mounting.
ÌCheck the release function every time after mounting.
ÌAfter manual release, the solenoid must be energized briey to re-es-
tablish guard locking.
ÌThe auxiliary release must be reset 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). See ENISO14119:2013,
sec. 5.7.5.4.
ÌThe auxiliary release is not a safety function.
ÌThe correct function must be checked at regular intervals.
ÌObserve the notes on any available data sheets.

10.2. Teaching-in 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.
The zero sequence is output during a teach-in operation.
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.
Important!
ÌThe teach-in operation can be performed only if the device does not have any internal fault.
ÌDevices in the condition as supplied remain in teach-in standby state until they have successfully
taught-in the rst actuator. Once taught-in, switches remain in the teach-in standby state for approx.
3min. after each switch-on.
ÌThe 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.
ÌThe safety switch can be operated only with the last actuator taught-in.
ÌIf the switch detects the actuator that was most recently taught-in when in the teach-in standby state,
this state is ended immediately and the switch changes to normal operation.
ÌThe actuator to be taught-in is not activated if it is within the actuating range for less than 30s.
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/DIA LED repeatedly ashes 3x green.
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/DIA LED ashes green (approx. 1Hz).
After successful teach-in, the STATE/DIA and ASI LEDs ash alternately red/green.
Teach-in errors are indicated by the STATE/DIA LED illuminating red and a green ashing code of the STATE/DIA LED
(see chapter 11. System status table on page 15).
3. Switch off operating voltage (min. 3s).
¨The code of the actuator that was just taught-in is activated in the safety switch.
4. Switch on operating voltage.
¨The device operates normally.

ÌBefore carrying out the functional check, make sure that there are no persons in the danger zone.
ÌObserve the valid accident prevention regulations.
10.3.1. Mechanical function test
The actuator must slide easily into the switch. Close the guard several times to check the function.
10.3.2. Electrical function test
After installation and after 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 STATE/DIA LED then ashes green at regular intervals.
2. Close all guards.
¨The machine must not start automatically.
¨The STATE/DIA LED (green) and the yellow LOCK LED are illuminated continuously.
3. Enable operation in the control system.
4. Open the 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.
Check every safety guard to ensure that activating the guard locking will not affect the safety function.

12.1.1. Typical system times
Refer to the technical data for the exact values.
Ready delay: After switch-on, the device carries out a self-test. The system is ready for operation only after this time.
Turn-on time: The max. reaction time ton is the time from the moment when the guard is locked to the moment when the
code sequence is transmitted.
Risk time according to EN 60947-5-3: If an actuator moves outside the actuating range, transmission of the code
sequence on the corresponding safety switch is deactivated at the latest after the risk time.
