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)
