8.1
INITIAL COMMISSIONING
Air pockets around the bearings!
The device can be destroyed.
▶ Make certain that with installation orientation "drive shaft up" the pump
housing is completely filled with hydraulic fluid during commissioning and in
operation.
▶ Check the hydraulic fluid level in the pump case at regular intervals. If
required, carry out recommissioning. For tank-top installation, the case
chamber can run dry through the case drain line (ingress of air via the
shaft seal ring) or via the working line (gap losses). The bearings are thus
insufficiently lubricated when the pump is restarted.
▶ Ensure that the suction line is always filled with hydraulic fluid during
commissioning and operation.
When carrying out any work in conjunction with commissioning of the SY(H)
DFED control system, observe the general safety instructions and intended use
in chapter 2 "Safety instructions" on page 10.
8.1.1
Filling the SY(H)DFED control system
Spilled hydraulic fluid!
Discharging or spilling hydraulic fluid while filling the SY(H)DFED control system
can lead to environmental pollution and contamination of the groundwater.
▶ When filling in and changing the hydraulic fluid, always place an oil drain pan
under the SY(H)DFED control system.
▶ Observe the information in the safety data sheet for the hydraulic fluid and the
instructions provided by the system manufacturer.
You will require an approved hydraulic fluid:
The machine or system manufacturer can provide you with precise data of the
hydraulic fluid. Details on minimum requirements for HFC hydraulic fluids (for
SYHDFED only) are available in the Rexroth publication 92053.
To ensure functional reliability of the SY(H)DFED control system, the hydraulic
fluid must comply at least with cleanliness class 18/16/13 according to ISO 4406
for particle sizes 4/6/14 μm. For permissible temperatures, see data sheet of the
relevant control system.
The SY(H)DFED control system should be filled using a filling and filtration unit
(10 µm filtration rating). The control system must not be powered when being
filled.
1. Fill and air-bleed the SY(H)DFED control system via the appropriate ports, see
chapter 7.3 "Installation positions and piping of SY(H)DFED systems" on page
43. The hydraulic lines of the system must also be filled.
2. Test the direction of rotation of the drive motor. To do this, rotate the motor
briefly at the lowest rotational speed (jogging). Make sure that the direction of
rotation of the SY(H)DFED control system corresponds to the indication on the
