15 Troubleshooting
The following table may assist you in troubleshooting. The table is not exhaustive.
In practice, problems which are not listed here may also arise.
15.1
HOW TO PROCEED FOR TROUBLESHOOTING
▶ Always work systematically and purposefully, even when under time pressure.
Random and imprudent disassembly and changing of settings can, in the worst-
case scenario, result in the inability to determine the original cause of error.
▶ First obtain a general overview of how your product works in conjunction with
the entire system.
▶ Try to find out whether the product has functioned properly in conjunction with
the overall system before the fault occurred.
▶ 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 operating
range?
– Were there any changes (e.g. retrofit) or repairs carried out on the complete
system (machine/system, electrics, control) or on the product? If yes: 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 error cause. If possible, ask the direct (machine)
operator.
▶ If you cannot rectify the error, contact one of the contact addresses which can
be found at:
