Detection and display of sensor and wiring errors

Break of the supply-

1)

, measuring or sense lines: "

FAIL

" on the process value display and

"

FbF.1

" in the error list are displayed.

Wrong polarity of supply, sense and input signal lines: "

FAIL

" on process value display and

"

POL.1

" in error list are displayed. 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.)

Short circuit of supply and sense lines ==> behaviour as with break of the supply lines: "

FAIL

"

on the process value display and "

FbF.1

" in the error list are shown.

Short circuit of measuring lines: measuring signal = 0

Overshoot of measurement input: “

FAIL” on process value display and "

FbF.1

" in the error list

are displayed.

Entry of a substitute value (

In.F ) effective in the event of a sensor error is possible.

*

1)

With 4-wire connection, the EX+ line is monitored in addition to the measurement lines.

After a break of the EX minus line, the measured value is not plausible.
