14 Troubleshooting
The Table 14 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).
▶ Work systematically and in a targeted manner, 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 functions 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.
▶ If the fault cannot be corrected, please refer to one of the contract addresses at:
