Operation

Bosch Rexroth AG, manifolds and modules, RE 07601-B/12.2013
When commissioning the manifold/module at a system, first of all commission the
electronics that might exist and then the hydraulics. When commissioning the
electronics, the hydraulics (power unit, valve etc.) must be switched off in order
to prevent damage at the hydraulic components caused by incorrect wiring and
malfunctions of the electronics.

8.6.1 Bleeding the hydraulic system

For bleeding the overall system, observe the operating instructions of the device
and/or system into which the manifold is installed.
Switch the manifold/module several times under 50 % of the operating pressure
before placing it into full operation so that air which has remained in the manifold/
module can exit. Thus, mechanical damage being caused by inadmissibly high accel-
eration of the fluid and the valve spools is avoided and the life cycle of the manifold/
module is extended.
9 Operation
Moving actuation elements!
Hand lever, actuation rollers or other actuation elements at mechanically operated
hydraulic valves perform movements during operation. This may lead to the jam-
ming or bruising of parts of the body.
▶ When switching the hydraulic valves, pay attention to moving actuation elements.
loud noise!
Hearing damage and possible damage at hydraulic valves! In case of an unfavorable
arrangement of hydraulic manifolds and modules in the system, resonance or fluid
noises e.g. whistling may result.
▶ In this case, contact a service engineer.
For more information on the operation, please refer to the operating instructions
for the hydraulic system into which the manifold or the module is installed.
