14 Troubleshooting
Table 13 is intended to support troubleshooting. This table is not exhaustive.
Issues may occur in practice that are not listed here. Only authorized personnel
may perform troubleshooting inside a safety area designated by the machine
manufacturer.
14.1
How to proceed for troubleshooting
▶
Perform troubleshooting if possible with reduced operating data
(e.g. slowly swinging in or out and slow pressure increase).
▶
Use a systematic and targeted approach, even when pressed for time. Random,
indiscriminate removal and changing of settings could make it impossible
to determine the original cause of the fault.
▶
First get a general idea of how your product works in conjunction with
the entire system.
▶
Try to find out whether or not the product was working properly in conjunction
with the entire system before the fault occurred.
▶
Try to determine any changes to the entire system in which the product
is installed:
–
Have there been any changes to the application conditions or operating range
of the product?
–
Has maintenance work recently been carried out? Is there an inspection
or maintenance log?
–
Have any changes (e.g. upgrades) or repairs been made to the overall system
(machine/system, electrics, control) or to the product? If yes: What changes?
–
Has the hydraulic fluid been changed?
–
Has the product or machine been used as intended?
–
How does the malfunction appear?
▶
Try to get a clear idea of the cause of the fault. Directly ask the (machine)
operator.
▶
Document the work carried out.
▶
