WARNING
Escaping hydraulic fluid mist!
Risk ofexplosion and fire hazard, health hazard, risk ofenvironmental pollution!
▶ Depressurize therelevant machine/system component and repair theleak.
▶ Only perform welding work when themachine/system isdepressurized.
▶ Keep open flames and ignition sources away from theaxial piston unit.
▶ If axial piston units are located inthe vicinity ofignition sources orpowerful
thermal radiators, ashield must beerected toensure any escaping hydraulic
fluid cannot beignited, and toprotect hose lines from premature aging.
Electrical voltage!
Risk ofinjury from electric shock orrisk ofproperty damage!
▶ Always disconnect thevoltage supply tothe relevant machine/system part
before installing theproduct and/or connecting ordisconnecting theconnector.
Protect themachine/system against being re-energized.
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.
Limitation oftheclosed loop control and/or open loop 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.
