2 Notes on Safety
The product has been manufactured according to the accepted rules of current
technology. Even so, there is risk of injury and damage to equipment if the following
chapter and safety instructions of this documentation are not followed.
O Read these instructions completely before working with the product.
Intended use
The LU6 locking unit is a safety component in accordance with the Machinery
Directive 2006/42/EC and is provided with a CE mark. The intended purpose
is to statically hold and dynamically brake the piston rod of AVENTICS cylinders
in accordance with ISO 15552 or equivalent round bars in any mounting orientation.
The holding force/braking force takes effect in both directions of movement as well
as in any piston rod or round bar position. The holding cartridge and the LU6 locking
unit or round bar are subject to natural wear, which does not impact on the function
within the specified performance parameters.
O See section "Technical Data" for the standards and parameters complied with,
adhered to, and required by the product.
O See the declaration of conformity for product-relevant directives.
Improper use
Improper use of the product includes:
W
Use in non-industrial applications/residential areas,
W
Use outside of the product limits defined in the technical data,
W
Unauthorized modifications,
W
Use of a lubricator in the system compressed air supply,
W
Excessive lubrication of the piston rod or round bar,
W
Use of a non-permissible piston rod or round bar lubricant,
W
Use in explosive areas (ATEX).
Personnel qualifications
Assembly, installation, commissioning, maintenance, and decommissioning may
only be carried out by qualified personnel that have the required knowledge of and
experience in dealing with electrical and pneumatic control technology.
General safety instructions
W
Observe the regulations for accident prevention and environmental protection.
W
Observe the safety instructions and regulations of the country in which
the product is used or operated.
W
Only use AVENTICS products that are in perfect working order.
W
Follow all the instructions on the product.
W
Only use accessories and spare parts approved by the manufacturer.
W
Comply with the technical data and ambient conditions listed in these operating
instructions.
W
If there is a malfunction, do not attempt unauthorized repairs. Instead, contact
your nearest AVENTICS sales office.
W
You may only commission the product if you have determined that the end
product (such as a machine or system) in which the AVENTICS products are
installed meets the country-specific provisions, safety regulations,
and standards for the specific application.
W
Wear appropriate protective clothing, safety goggles and, if necessary, a helmet
during assembly. Observe the applicable occupational safety regulations
for the system.
Product-related safety notes
O Comply with the further requirements of ISO 13849-1 (e.g. CCF, DC, PL
if you intend to use the product in higher categories (2 to 4).
O Make sure that the maximum number of switching cycles (B
of use T (typical assumption according to ISO 13849-1 = 20 years) or that the
M
maximum total braking energy (see chapter "Technical Data") is not exceeded.
If the expected number of switching cycles for a component exceeds the B
value during its period of use, suitable exchange intervals have to be specified.
O Perform a function test on the LU6 locking unit at least once per month.
O Make sure that the fundamental and proven safety principles in accordance
with ISO 13849-2 for implementation and operation of the LU6 locking unit
in the system are complied with.
Safety function according to ISO 13849
The LU6 locking unit is a component in accordance with ISO 13849-1 requirements
that guarantees the safety functions "prevention of unexpected start-up" and "safe
stop function" even in case of a fault in the valve that controls the cylinder.
With the LU6 locking unit in combination with the optional IN1 sensor, you can
achieve performance level e (PL e) if integrated correctly. This is application-
dependent.
