15. Troubleshooting
15.1 How to proceed
›
Get an overview on the function of the product in connection with the overall system.
›
Try to find out whether the product had provided the required function in the overall system before the error occurred.
›
Try to detect changes in the overall system, into which the product has been installed:
» Have the operating conditions or the operating range of the product changed?
» Have modifications (e.g. conversions) or repairs been carried out at the overall system
(device / unit, electrics, control) or at the product? If so, which modifications?
» Has the product or the device been operated correctly?
» How does the fault tend to show?
›
Get a clear impression about the cause of trouble. Possibly consult the direct operator or machine operator.
