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 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.
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 6.2. Switching states on page 9):
- When guard locking is released, no valid code sequence is sent (monitoring of the locking device).
- When the guard is open, no valid code sequence is sent (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 12. Technical data on page 17).
Activation of guard locking by switching on/off the auxiliary voltage
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 control of guard locking, because the guard locking solenoid is
completely disconnected from outside the device via the auxiliary power (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 dened only by the external control (e.g. PFHD ext. for the standstill
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 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 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 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 assignment ensures a particularly high level of protection against tam-
pering. The system thus possesses a high coding level.
ÌDevices with multicode evaluation: Unlike systems with unicode evaluation, on multicode 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 (multi-
code 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, guard locking is effective and the coding 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 unlocked.
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-L2
(guard locking actuated by power-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 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.
The zero sequence is sent via the ASi bus when the auxiliary release or the auxiliary key release
is actuated.
Open the guard and close it again after resetting the auxiliary release. The device will then
operate normally again.
Important!
ÌThe actuator must not be under tensile stress during manual re-
lease.
ÌReset the auxiliary release and cover it with a new seal label after
use.
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-establish guard locking.
ÌThe auxiliary release must be reset at the control system lev-
el, 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 enclosed data sheets.

10.2. 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.
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 ap-
prox. 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.
10.2.1. 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/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).
The STATE/DIA LED ashing (alternately red/green) acknowledges the successful teach-in operation.
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 16).
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.
