14 Troubleshooting
Table 13 and may help you when troubleshooting. The Table makes no claim for
completeness.
In practical use, problems which are not listed here may also occur.
14.1 How to proceed for troubleshooting
▶ Always act systematically and purposefully, even under pressure of time. Random
and imprudent removal and changing of settings could result in the inability to
ascertain the original failure cause.
▶ First obtain a general overview of how your product works in conjunction with the
entire system.
▶ Try to find out whether the product has worked properly in conjunction with the
entire system before the fault occurred.
▶ Try to determine any changes of the entire system in which the product is
integrated
– Were there any changes to the product’s application conditions or operating
range?
– Has maintenance work recently been carried out? Is there an inspection or
maintenance log?
– Were changes (e.g. conversions) or repairs made to the complete system
(machine/system, electrics, control) or on the product? If yes, which?
– Has the hydraulic fluid been changed?
– Was the product or machine operated as intended?
– How did the malfunction appear?
▶ Try to get a clear idea of the error cause. Directly ask the (machine) operator.
▶ Document the work carried out.
▶ If you cannot rectify the error, contact one of the contact addresses which can be
