2 Safety
Before using the Safety Locking Device, a risk evaluation must be performed
according to valid standards (e.g. EN ISO 12100-1, EN ISO 13849-1,
EN ISO 14121). For mounting, operating and testing, document L100 Safe imple-
mentation and operation, application information as well as all applicable national
and international standards, regulations, rules and directives must be observed.
Observe and print out relevant and supplied documents and distribute to the
affected personnel.
The following standards apply for the risk evaluation at the protective device prior
to using the Safety Locking Device:
• EN ISO 14121, Safety of machinery, risk evaluation
• EN ISO 12100-1, Safety of machinery
• EN ISO 13849-1, Safety-related parts of control systems
The realizable category of the integration in control circuits according to
EN ISO 13849-1 is dependent on the used contact block and wiring.
In particular, the following national and international legal regulations apply for the
start-up, technical inspections and work with Safety Locking Devices:
• Machinery directive 2006/42/EC
• Low voltage directive 2006/95/EC
• Electromagnetic compatibility directive 2004/108/EC
• Use of work equipment directive 89/655 EEC
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and Labor Protection Act
• Device Safety Act
WARNING
Serious accidents may result if the voltage supply is interrupted!
If the voltage supply to the electromagnet of an electromagnetically locked
Safety Locking Device is interrupted, the protective device may be opened
immediately.
For safety-related information you may also contact the local authorities (e.g.,
industrial inspectorate, employer's liability insurance association, labor inspec-
torate, labor protection and health authority).

2.1 Approved purpose and foreseeable improper operation
2.1.1 Proper use
• The Safety Locking Device must only be used after it has been selected in
accordance with the respectively applicable instructions and relevant stan-
dards, rules and regulations regarding labor protection and safety at work,
and after it has been installed on the machine, connected, commissioned,
and checked by a competent person.
• When selecting the Safety Locking Device it must be ensured that its safety-
related capability meets or exceeds the required performance level PLr
ascertained in the risk assessment.
• It must be in perfect condition and inspected regularly.
• The switching process must only be triggered by an actuator approved for
this Safety Locking Device that is connected to the moveable guard in a
non-detachable and tamperproof manner.
L100 Safety Locking Devices must be connected in such a way that a dangerous
state can only be activated while the protective device is closed and so that they
prevent premature opening during the lag time before the dangerous state has
ended. Electromagnetic Safety Locking Devices may only be used instead of
spring-locked Safety Locking Devices in exceptional cases and following appro-
priate risk evaluation.
Connection conditions:
• dangerous state can be activated only with closed protective device and
locked locking device
• protective device cannot be opened while locking device is locked
WARNING
A running machine can cause severe injuries!
ªMake certain that, duringall conversions, maintenance work and inspections,
the system is securely shut down and protected against being restarted
again.

Furthermore, the L100 Safety Locking Device must not be used under the
following conditions:
• high concentration of dust particles in the surrounding area
•rapidly changing ambient temperature (leads to condensation)
• in the event of strong physical shocks
• in explosive or easily flammable atmospheres
• the mounting locations are not sufficiently stable
• in the event of electromagnetic interference
• the safety of multiple persons is dependent on the function of this Safety
Locking Device (e.g. nuclear power plants, trains, aircraft, motor vehicles,
incinerators, medical devices)
Handling the Safety Locking Device:
ªNever unlock the SafetyLocking Device before the dangerous state has ended.
ªObserve the permissible environmental conditions for storage and operation
(see chapter 14).
ªImmediately replace damaged Safety Locking Devices according to these
instructions.
ªUse cable gland, insulation materials and connecting wires of the appropriate
protection rating.
ªProtect the Safety Locking Device from penetrating foreign bodies (e.g. shav-
ings, sand and blasting agent).
ªBefore performing painting work, cover the actuation slot, actuator and name
plate.
ªImmediately clean any contamination from the Safety Locking Device that
impacts function according to these instructions.
ªMake no structural changes to the Safety Locking Device.
ªThe Safety Locking Device must be exchanged after a maximum of 20 years.
2.1.2 Foreseeable misuse
Any use other than that defined under the "approved purpose" or which goes
beyond that use of the Safety Locking Device is considered improper use!
E.g. - using without non-detachably mounted actuator
• looping into the safety circuit parts that are not relevant to safety
• using the locking device as a limit stop

3 Device description
The Safety Locking Device of the L100 series is an electro-mechanical switching
device in a housing made of glass-fibre-reinforced and non-combustible plastic;
the device satisfies protection rating IP 66. By means of the funnel-shaped inser-
tion opening, the actuator self-centers, even if the door is slightly misadjusted. The
magnet switched currents can be reduced for both variants (adjustable via a
switch). The spring-actuated models (L100-Pxxx-SLM24) are equipped with an
auxiliary release located below the deflection head.

Functions
14 L100 Leuze electronic
4 Functions
4.1 Spring locking
With the L100-P3C3-M20-SLM24 and L100-P4C3-M20-SLM24, the safety
contacts close when the actuator moves in, and the actuator is mechanically held
in the locked position bythe spring force. The dangerous process can be activated
via the safety switching device.
After the dangerous process has stopped, the operating voltage for unlocking the
electromagnet is applied and the actuator is released. The protective device can
be opened. Inthe event of failure of the operating voltage, release is also possible
via the auxiliary release.
4.2 Electromagnetic locking
With the L100-P3C3-M20-MLM24, the safety contact for the position monitoring
of the protective device closes when the actuator is moved in. The electromagnet
is energized and holds theactuator in thelocked position. The dangerous process
can be activated via the safety switching device.
On release, the voltage supply to the electromagnet is interrupted. The electro-
magnet releases the actuator and the protective device can be opened.

Applications
Leuze electronic L100 15
TNT 35/7-24V
5 Applications
Safety Locking Devices with spring locking are suitable for e.g. position monitoring
and locking the following protective devices:
• turning or swiveling moveable guards
• laterally moveable protective gratings or sliding gates
Safety Locking Devices with electromagnetic lock are used primarily as locks for
moveable guards to prevent undesired process interruptions.
By means of the switched-current reduction option, larger systems can be
equipped with multiple L100 Safety Locking Devices. With magnet activation,
possible voltage peaks associated with switching on and off can be reduced in this
way.
