11.3 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The rst measures are:
•
Evaluation of fault messages via the display and adjustment
module
•
Checking the output signal
•
Treatment of measurement errors
Further comprehensive diagnosis possibilities are oered by a PC
with the software PACTware and suitable DTM.
In many case, the failure reasons can thus be determined and faults
rectied.
The following table describes possible errors with the output signal
and helps to remove them:
Error Reason Removal
Output signal not stable Level uctuations Set damping appropriate to the instrument via
the display and adjustment module or PACT-
ware/DTM
Output signal missing Electrical connection faulty Check connection according to chapter
"Connection steps" and if necessary, correct ac-
cording to chapter "Wiring plan"
Voltage supply missing Check cables for breaks; repair if necessary
Operating voltage too low Check, adapt if necessary
The following table describes possible faults that may not generate an
error message:
