For output signals
Error
Possible causes
Solution
Signal output outside the valid
range
Main electronics module is
defective.
Order spare part → See 14.2.
Signal output outside the valid
current range
(< 3.6 mA or > 22 mA)
I/O electronics module is defective. Order spare part → See 14.2 .
Device shows correct value on local
display, but signal output is
incorrect, though in the valid range.
Configuration error
Check and correct the parameter
configuration.
Device measures incorrectly.
