How to proceed for troubleshooting
12.1
Always work systematically and focused, even when under time pressure.
f
Random and imprudent disassembly and readjustment of settings might result
in the inability to restore the original error cause.
First get a general idea of how your product works in conjunction with the
f
overall system.
Try to find out whether the product has worked properly in conjunction with the
f
overall system before the error occurred first.
Try to determine any changes of the overall system in which the product
f
is integrated:
Were there any changes to the product's operating conditions or operat-
–
ing range?
Were there any changes or repair works on the overall system (machine/sys-
–
tem, electrics, control) or on 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 fault. Ask the direct (machine) op-
f
erator, if necessary.
