" is displayed on the process value
display and “
FbF.1
" in the error list.
(A substitute value (In.F ) can be entered in the event of a sensor error.)
2)
Wrong polarity of supply, sense and input signal lines: "
FAIL
" appears on the process value
display and "
POL.1
" in the error list. Detection of wrong polarity of sense takes place
during instrument start-up.
Subsequent correction of the sense wiring is detected only after instrument re-start (i.e.
the instrument must be switched off and on again.)

appears on the process value display and "
FbF.1
" in the error list.
