Safety instructions 11/104
RE 92076-01-B/10.2017, A4... with HS5E pilot control valve/Series 3x,
Bosch Rexroth AG
The axial piston unit is only intended for professional use and not for private use.
2.3 Improper use
Any use other than that described as intended use shall be considered as improper
and is therefore impermissible.
Bosch Rexroth AG is not liable for damages resulting from improper use. The user
shall bear all risks arising from improper use.
The following foreseeable faulty usages are also be considered to be improper (this
list does not claim to be exhaustive):
•
Use outside the operating parameters approved in the data sheet or in the order
confirmation (unless specifically approved by the customer)
•
Use of non-approved fluids, e.g. water or polyurethane components
•
Changes to factory settings by unauthorized persons
•
Use of add-ons (e.g., control unit, valves) not in combination with the specified
Rexroth components
•
Use of the axial piston unit with assembled parts under water at a depth of more
than 10 meters without the necessary additional measures, for example pressure
equalization. Units with electrical components (e.g. sensors) generally cannot
come into contact with water.
•
Use of the axial piston unit under a continuous pressure differential from case
pressure to ambient pressure of greater than 2 bar, whereby the ambient pressure
must always be lower than the case pressure. Short-term pressure peaks (
t
< 0.1 s)
of up to 4 bar are permitted. Beyond this, the maximum case pressure specified on
the data sheet cannot be exceeded.
•
If you do not comply with the domestic EMC regulations for the present application.
If you need information about EMC-compliant installation, refer to Bosch Rexroth’s
EMC test documentation (see chapter “Electrical connection of the pilot valve”
on page 96). Ensuring compliance with the limit values required by national
regulations is the responsibility of the manufacturer of the system or machine.
European countries: EU Directive 2014/30/EU (EMC Directive); USA: See the
national electrical system regulations (NEC), National organization of the
manufacturers of electrical systems (NEMA) as well as regional building regulations
•
Use of the HS5E control system in an explosive environment unless the component or
machine/system has been certified as being compliant with ATEX directive 2014/34/EU.
•
Use of the axial piston unit in a corrosive atmosphere
•
Use of the axial piston unit in aircraft or spacecraft
