2.1 Intended operation
Intended operation
The valves may only be operated as a component part of a higher-level overall
system, for example in a machine.
They may be used only as control elements to control flow and/or pressure in
hydraulic circuits that regulate position, speed, pressure and power.
The valves are intended for use with mineral-oil-based hydraulic oils. Use with
other media requires our prior approval.
Correct, reliable and safe operation of the valves requires qualified project
planning as well as proper utilization, transportation, storage, mounting, re-
moval, electrical and hydraulic connection, start-up, configuration, operation,
cleaning and maintenance.
The valves may only be started up when the following is ensured:
• The higher-level machine with all of its installed components complies
with the latest versions of the relevant national and international regula-
tions, standards and guidelines (such as e.g., the EU Machinery Directive,
the regulations of the trade association and of TÜV or VDE).
• The valves and all of the other installed components are in a technically
fault-free and operationally reliable state.
• No signals which can lead to uncontrolled movements in the machine are
transmitted to the valves.
Intended operation also includes the following:
• Observation of this user manual
• Handling of the valves in accordance with safety requirements
Chapter "2.2 Handling in accordance with safety requirements", page 6
• Adherence to all of the inspection and maintenance instructions of the
manufacturer and the operator of the machine
• Observation of all product-related hardware and software documentation
relevant to the particular application
• Observation of all safety standards of the manufacturer and the operator
of the machine relevant to the particular application
• Observation of all the latest versions of the national and international reg-
ulations, standards and guidelines relevant to the particular application
(such as e.g., the EU Machinery Directive, the regulations of the trade as-
sociation and of TÜV or VDE)
WARNING
The valves may be operated exclusively within the frame-
work of the data and applications specified in the user
manual.
Any other or more extensive use is not permitted.
WARNING
Use of the valves in potentially explosive environments is
not permitted.
