VEGAPULS 42 • Three-wire with IO-Link (2 x transistor or 4 … 20 mA plus 1 x transistor)
1016153-EN-230316
Liquids: Measurement error during emptying
Fault description
Cause
Rectification
Measured value remains un-
changed in the close range
during emptying
Level
time
0
False signal larger than the level echo
Level echo too small
Check measuring point: Antenna should
protrude out of the threaded mounting
socket, possible false echoes through
flange socket?
Remove contamination on the antenna
In case of interferences due to instal-
lations in the close range: Change
polarisation direction
After eliminating the false signals, the
false signal suppression must be de-
leted. Carry out a new false signal
suppression
Measured value jumps spo-
radically towards 100 %
during emptying
Level
time
0
Varying condensation or contamination
on the antenna
Carry out false signal suppression or in-
crease false signal suppression in the
close range by editing
With bulk solids, use radar sensor with
purging air connection
10.6 Software update
The device software is updated via Bluetooth.
The following components are required:
•
Instrument
•
Voltage supply
•
PC/notebook with PACTware/DTM and Bluetooth USB adapter
•
Current instrument software as file
You can find the current instrument software as well as detailed infor
-
mation on the procedure in the download area of our homepage.
Caution:
Instruments with approvals can be bound to certain software versions.
Therefore make sure that the approval is still effective after a software
update is carried out.

page.
10.7 How to proceed if a repair is necessary
You can find an instrument return form as well as detailed information
about the procedure in the download area of our homepage. By doing
this you help us carry out the repair quickly and without having to call
back for needed information.
Proceed as follows in case of repair:
•
Print and fill out one form per instrument
•
Clean the instrument and pack it damage-proof
•
Attach the completed form and, if need be, also a safety data
sheet outside on the packaging
