12/60 Safety instructions
Bosch Rexroth AG, A15VSO/A15VLO Series 11, RE 92801-01-B/11.2018
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
properly 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 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 properly implemented.
