RECOMMISSIONING AFTER STANDSTILL

Depending on the installation and ambient conditions, changes may occur in the
system which make recommissioning necessary.
Among others, the following criteria may result in the necessity for
recommissioning:
• Air in the hydraulic system
• Water in the hydraulic system
• Aged hydraulic fluid
• Contamination
▶ For recommissioning, proceed as described in chapter 8.1 "Initial
commissioning" on page 60.
8.3

RUNNING-IN PHASE

Viscosity too low!
Risk of damage! The increased temperature of the hydraulic fluid during the
running-in phase can cause the viscosity to drop to impermissible levels.
▶ Monitor the operating temperature during the running-in phase.
▶ Reduce the loading (pressure, speed) of the SYDFE1 control system, if
impermissible operating temperatures and/or viscosities occur.
Bearings and sliding surfaces are subject to a running-in phase. Increased friction
at the start of the running-in phase results in increased heat generation which
decreases with increasing operating hours. The volumetric and mechanical-
hydraulic efficiency rises as well by the end of the running-in phase of approx.
10 operating hours.

9 Operation

The SYDFE1 control system is a component which requires no adjustments or
changes to be made during operation. For this reason, this chapter of the manual
does not contain any information on adjustment options. Only use the product
within the performance range provided in the technical data. The machine
or system manufacturer is responsible for the correct project planning of the
hydraulic system and its control.
