A4... with HS5E(V)(L) control system Series 1x and 30 | Commissioning
Bosch Rexroth AG, RE 92076-01-B/2021-04-22
8.1.9 Saving parameters
After carrying out commissioning, you should save the parameter set of the HS5E
pilot control valve. If an error occurs, this is the only way to restore the parameters
or transfer them to a replacement valve.
Fig. 33: Back-up of parameters
Please back up the parameters as follows
▶ Use the parameterization menu to select "Save"
▶ Select the memory path in the separately opened window and select and save
"all parameters" under parameter selection.
8.2 Running-in phase
Property damage due to insufficient viscosity!
Elevated hydraulic fluid temperature may excessively reduce viscosity and damage
the product!
▶ Monitor the operating temperature during the running-in phase, e.g. by
measuring the leakage temperature.
▶ Reduce the loading (pressure, rotational speed) of the axial piston unit if
unacceptable operating temperatures and/or viscosities occur.
▶ Excessively high operating temperatures indicate faults that have to be analyzed
and eliminated.
The bearings and sliding surfaces are subject to a running-in phase. The increased
friction at the start of the running-in phase results in increased heat development
which decreases with increasing operating hours. Volumetric and mechanical-
hydraulic efficiency is also greater until the running-in phase of about 10 operating
hours is concluded.
To ensure that contamination in the hydraulic system does not damage the axial
piston unit, Bosch Rexroth recommends the following procedure after the running-
in phase:
