2Safety
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 "Safe implemen-
tation and operation of the L10" as well as all applicable national and international
standards, regulations, rules and directives must be observed (e.g. machinery
directive, low-voltage directive, work-equipment directive, safety regulations,
accident-prevention regulations, EN 1088, EN ISO 13849-1, EN 60204-1,
EN 954-1). Observe and print out relevant and supplied documents and distribute
to the affected personnel.
ªBefore beginning work with the Safety Locking Device, completely read and
understand the documents applicable to the respective task.
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 and EN 954-1 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
• Use of work equipment directive 89/655 EEC
• Safety regulations
• Accident-prevention regulations and safety rules

Review state, , Monday, 19. January 2009
2.1 Proper use
To ensure proper personnel protection, the Safety Locking Device must be
mounted, connected and started-up by trained personnel. 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.
The rules and regulations for protection and safety at work and the recognised
safety-related rules and regulations must be observed. These include:
• EN 1088, Interlocking devices associated with guards
• EN ISO 13849-1, Safety-related parts of control systems
• EN 60204-1, Electrical equipment of machines
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 unlocking of the locking device while the machine is running triggers
a STOP command; the dangerous state is ended before the protective
device can be opened
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 physical shocks
• in explosive or easily flammable atmospheres
• the mounting locations 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)

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-fibre-reinforced and non-combustible
plastic; the device satisfies protection rating IP 67. By means of the funnel-shaped
insertion opening, the actuator self-centres, even if the door is slightly misad-
justed. The locking/unlocking delay is manually adjusted by means of a knurled
nut.

2 Insertion opening for actuator
3 Dust cover
4 Knurled nut for locking/unlocking (delaysee chapter 14 "Technical data")

90° increments. By means of 5 possible approach directions and a selection of
different actuators, the Safety Locking Device can be mounted in any position.

Functions
Review state, , Monday, 19. January 2009
4 Functions
The positive-opening contacts close if:
• the actuator is moved in
• the locking device is locked
The dangerous state can only be activated via the safety switching device while
the safety contacts are closed. During the first clockwise turns of the knurled nut,
the contacts are opened and a STOP signal is transmitted to the downstream
safety switching device. The actuator is not released until the knurled nut has
been turned to the right limit stop and the locking device has unlocked. During this
manual time delay (delay time see chapter 14 "Technical data"), the dangerous
state must be stopped in order for the protective device to be opened safely. The
Safety Locking Device can only be locked if the actuator is moved in.
Figure 4.1: Example for the manual delay
1 Machine is running, locking device is locked
2 Machine coasts as the knurled nut is turned
3 Machine has stopped, locking device is unlocked
4 Protective device can be opened
5 Applications
The Safety Locking Device is suitable for e.g. the following protective devices:
• turning or swivelling moveable guards
• laterally moveable protective gratings or sliding gates
• seldom used maintenance doors or covers
1234
The manual locking/unlocking function makes the L10 Safety Locking Device
suitable for systems with protective devices that are used only occasionally or
that are located relatively far away on which no magnet activation is provided.
