14 Troubleshooting

Table 14 may help you with troubleshooting. This table does not cover everything.
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 with troubleshooting

▶ Preferably perform the troubleshooting with reduced operating data (e.g., slowly
swinging in or out and slow pressure increase).
▶ Proceed in a systematic and purposeful manner, even when pressed for time.
Random and imprudent removal and changing of settings could result in the
inability to ascertain the original cause of the fault.
▶ First obtain a general overview 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:
– 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?
– Have any changes (for example, upgrades) or repairs been made to the overall
system (machine/system, electronics, control) or to the product? If yes, which?
– Has the hydraulic fluid been changed?
– Has the product or machine been used as intended?
– How did 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 you cannot rectify the fault, contact one of the contact addresses which can be
