Before using the Safety Locking Device, a risk evaluation must be performed
according to valid standards (e.g. EN
ISO 14121). For mounting, operating and testing, document L10 Safe imple-

mentation and operati on, app licati on infor mation as wel l as all applic able na tional
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 sta nda rds a pply for the risk e val ua tion a t the protective dev ice 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
ISO 13849-1 is dependent on the used contact block and wiring.
EN
In particular, the fo llowin g nationa l and i nternationa l legal regulatio ns apply for the
start-up, technical inspections and work with Safety Locking Devices:
• Machiner y directive 2006/42/EC
• Low voltage directive 2006/95/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

ISO 12100-1, EN ISO 13849-1,
For safety-related information you may also contact the local authorities (e.g.,
industrial inspectorate, employer's liability insurance association, labor inspectorate, labor protection and health authority).

Safety
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 standards, 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 selecti ng the Sa fety Lock ing D evice it must be ens ure d th at i ts s afetyrelated 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.
WARNING
A running machine can cause severe injuries!
ª Make certain that, during all conversi ons, maintenan ce work and inspec tions,
the system is securely shut down and protected against being restarted
again.
L10 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 the
dangerous state has ended before the protective device can be opened. They
must not be used if the point of operation can be accessed during the lag time
before the dangerous state has ended.
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
• manual unl ock ing of the loc kin g de vice whil e the machi ne is running trig gers
a stop command; the dan gerous state is ended be fore the prote cti ve device
can be opened

Safety
Furthermore, the L10 Safety Locking Device must not be used under the following
conditions:
• lag time of the dangerous state is greater than the minimum time delay of
the manual actuator release
• high concentration of dust particles in the surrounding area
• rapidly changing ambient temperature (leads to condensation)
• in the event of strong phys ic al sho cks
• in explosive or easily flammable atmospheres
• the mounting loca tion s are not sufficiently stable
• 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:
ª Observe the permissible environmental conditions for storage and operation
(see chapter 14).
ª Immediately replace damaged Safety Locking Devices according to these
instructions.
ª Use cable gland, insulation materials and connecting wires of the appropriate
protection rating.
ª Protect the Safety Locking Device from penetrating foreign bodies (e.g. shav-
ings, sand and blasting agent).
ª Before performing painting work, cover the actuation slot, knurled nut or lock
and name plate.
ª Immediately clean any contamination from the Safety Locking Device that
impacts function according to these instructions.
ª Make no structural changes to the Safety Locking Device.
ª The 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
• giving the keys to unauthorized persons

2.2 Competent personnel
Prerequisites for competent personnel:
• suitable technical training
• knows the rules and regulations for labor protection, safety at work and
safety technology and can assess the safety of the machine
• knows the instructions for the Safety Locking Device and the machine
• was instruct ed by t he responsib le indi viduals on the mountin g and opera tion
of the machine and of the Safety Locking Device
2.3 Responsibility for safety
Manufacturer and operating company must ensure that the machine and implemented Safety Locking De vi ce func tio n pro perly and that all affected pers on s are
adequately informed and trained.
The type and content of all imparted information must not lead to unsafe actions
by users.
If Safety Locking Devices feature key operation, the keys may only be given to
authorized person s who ha ve be en ins truct ed on the in terplay of sy stem /mach ine
and the Safety Locking Device.
The manufacturer of the machine is responsible for:
• safe machine construction
• safe implementation of the Safety Locking Device
• imparting all relevant information to the operating company
• adhering to all regulations and directives for the safe starting-up of the
machine
The operating company is responsible for:
• instructing the operating personnel
• maintaining the safe operation of the machine
• adhering to all regulations and directives for labor protection and safety at
work
• regular testing by competent personnel

2.4 Exemption of liability
Leuze electronic GmbH + Co. KG is not liable in the following cases:
• Safety Locking Device is not used as intended
• safety notices are not adhered to
• mounting and electrical connection are not properly performed
• the manual delay time is not allowed to elapse (e.g. due to improper operation, use of auxiliary equipment or tampering)
• reasonably foreseeable misuse is not taken into account

Device description
3 Device description
The Safety Locking Device of the L10 series is an electro-mechanical switching
device in a housing made of metal or glass-fiber-reinforced and non-combustible
plastic; the devic e satisfies pro tection ratin g IP 67. By me ans of the f unnel-shaped
insertion opening, the actuator self-centers, even if the door is slightly misad
justed. The locking/unlocking delay is manually adjusted by means of either a
knurled nut or a key (2 pieces included with delivery). A possible time delay must
be taken into account separately in this case.
Various mechanical and temporal requirements can be realized inexpensively
with the available models.
