8.3 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
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 eliminate them:
Error
Reason
Rectification
4 … 20 mA signal not sta-
ble
•
Fluctuations of the
measured variable
•
Set damping appropriate to the instrument via the
display and adjustment module or PACTware/DTM
4 … 20 mA signal missing
•
Electrical connection
faulty
•
Check connection according to chapter "
Connection
steps
" and if necessary, correct according to chapter
"
Wiring plan
"
•
Voltage supply missing
•
Check cables for breaks; repair if necessary
•
Operating voltage too
low or load resistance
too high
•
Check, adapt if necessary
Current signal greater than
22 mA or less than 3.6 mA
•
Electronics module in the
sensor defective
•
Exchange the instrument or send it in for repair
Depending on the reason for the fault and the measures taken, the
steps described in chapter "
Setup
" must be carried out again or must
be checked for plausibility and completeness.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no.
