A4... with HS5E(V)(L) control system Series 1x and 30 15
/104
WARNING
Danger from unexpected machine movement!
Danger to life or risk of injury! Unintentional or careless actuation of the manual
override of the solenoids can cause unexpected machine movements.
▶ Use the manual override only for functional testing or in the event of technical
malfunctions.
▶ Using the manual override on a permanent basis (e.g. by wedging, blocking) is
not permitted.
▶ The use of the manual override is only permitted with limited technical data
(e.g. 0.25
×
maximum data).
▶ Check whether or not your machine requires additional safety measures for your
application to avoid unintentional actuation. If necessary, make sure these are
appropriately implemented.
▶ Wear suitable protective clothing.
Restriction of control function!
Risk of injury or property damage!
Under certain circumstances, moving parts in control equipment (e.g. valve spools)
can get stuck in an undefined position due to contamination (e.g. impure hydraulic
fluid, abrasion or residual dirt from components). As a result, the hydraulic fluid flow
and the build-up of torque in the axial piston unit can no longer respond correctly
to the operator’s specifications. Even the use of various filter elements (external or
internal flow filtration) will not rule out a fault but merely reduce the risk.
▶ Check whether your application requires remedial measures on your machine in
order to bring the driven consumer to a safe position (e.g. safe stop).
▶ If necessary, make sure these are appropriately implemented.
Escaping hydraulic fluid due to leakage of machine/system components!
Risk of burning and risk of injury due to escaping hydraulic fluid jet!
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Never attempt to block or seal the leak or hydraulic fluid jet with a cloth.
CAUTION
High noise development during operation!
Risk of hearing damage or hearing loss!
The noise emission of axial piston units depends on rotational speed, working
pressure and installation conditions, among other factors. The sound pressure level
may rise above 70 dB (A) in certain application conditions.
▶ Always wear hearing protection near a running axial piston unit.
