13 Troubleshooting
13.1 How to proceed for troubleshooting
▶
Always work systematically and focused, even when under time pressure. Ran-
dom, thoughtless changing of settings might result in the inability to restore the
original cause of error.
▶
First, get a general overview of how your product functions in conjunction with
the overall system.
▶
Try to find out whether the product has worked properly in conjunction with the
overall system before the error occurred first.
▶
Try to determine any changes of the overall system in which the product
is integrated:
– Were there any changes to the product's operating conditions or area of
application?
– Were there any changes (e. g. refittings) or have repairs been carried out at the
overall system (machine/system, electrical systems, control) or at the product?
If so: What were they?
– Was the product or machine used as intended?
– How did the fault become apparent?
▶
Try to get a clear idea of the cause of the error. Ask the direct (machine) operator.
