14 Troubleshooting
Table 18 is intended to help you with 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 troubleshoot
▶
Troubleshoot with reduced operating parameters when possible.
▶
Use a systematic and targeted approach, even when pressed for time. Random,
indiscriminate removal could make it impossible to determine the original cause
of a 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:
– Were there any changes to the product's application conditions or operating
range?
– Has maintenance 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, electronics, control) or to the product? If yes, what has been
done?
– 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, get in touch with one of the contact addresses
