VEGABAR 51 • 4 … 20 mA/HART
36713-EN-130321
Error code Cause Rectification
4 … 20 mA
signal not
stable
Level fluctuations – Set the integration time via the
display and adjustment module or
PACTware
No atmospheric pres-
sure compensation
– Check the pressure compensation
in the housing and clean the filter
element, if necessary
4 … 20 mA
signal miss-
ing
Connection to volt-
age supply wrong
– Check connection according to
chapter "Connection steps" and
if necessary, correct according to
chapter "Wiring plan"
No power supply – Check cables for breaks; repair if
necessary
Operating voltage
too low or load resist-
ance too high
– Check, adapt if necessary
Current sig-
nal greater
than 22 mA
or less than
3.6 mA
Electronics module
or measuring cell de-
fective
– Exchange the instrument or send it
in for repair
In Ex applications, the regulations for the wiring of intrinsically safe
circuits must be observed.
Error code Cause Rectification
E013 no measured value
available 8)
– Exchange the instrument or send it
in for repair
E017 Adjustment span too
small
– repeat with modified values
E036 no operable sensor
software
– Carry out a software update or send
instrument for repair
E041 Hardware error – 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 "Set up" may have to be carried out again.
8.3 Exchanging the electronics module
In case of a defect, the electronics module can be exchanged by the
user against an identical type. If no electronics module is available on
side, the module can be ordered from the agency serving you.
Ordering and exchange are possible with or without sensor serial
number. The electronics module with serial number includes order-
specific data such as factory setting, seal material etc. These are not
included in the electronics module without serial number.

8) Fault message can also appear if the pressure is higher than the nominal
range.
