Troubleshooting
14.1
How to proceed for troubleshooting
●
Always work systematically and purposefully, even when under time
pressure. Randomly and imprudently disassembling and modifying set‐
tings might in the worst case result in the inability to determine the origi‐
nal error cause.
●
First, get a general idea of how the product works in conjunction with the
entire system.
●
Try to find out whether the product had worked properly in conjunction
with the entire system before the error occurred.
●
Try to determine any changes of the entire system in which the product
has been installed:
–
Were there any changes to the product’s operating conditions or
operating range?
–
Were there any changes (e.g., refittings) or repairs carried out in
the entire system (machine, electrics, control) or at the product? If
yes: What were they?
–
Was the product or machine used as intended?
–
How did the malfunction become apparent?
●
Try to get a clear idea of the error cause. If possible, directly ask the
(machine) operator.
●
Document the error condition and compare it to the initial condition. If
you cannot remove the error, please contact one of the contact address‐
es which can be found at
