9.4 Rectify faults
Reaction when malfunctions occur
The operator of the system is responsible for taking suitable measures to rectify faults.
Procedure for fault rectification
The first measures are:
•
•
•
Evaluation of fault messages, for example via the display and
adjustment module
Checking the output signal
Treatment of measurement errors
Further comprehensive diagnostics options offer a PC with the software PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectified.
Check the 4 … 20 mA
signal
Connect a multimeter in the suitable measuring range according to
the wiring plan. The following table describes possible errors in the
current signal and helps to remove them:
