9 Maintenance and fault rectification
VEGADIF 65 • 4 … 20 mA/HART
36128-EN-130417
Error code Cause Rectification
4 … 20 mA
signal miss-
ing
Wrong connection to
voltage supply
– 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 6)
– 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.
9.3 Exchanging the electronics module
In case of a defect, the electronics module can be exchanged against
an identical type by the user. If no electronics module is available on
site, the module can be ordered from the agency serving you.
In Ex applications only one instrument and one electronics module
with respective Ex approval may be used.
The sensor serial number is required to order an exchange electron-
ics. You will find this number on the type label of the instrument or on
the delivery note.
9.4 Software update
The software version of VEGADIF 65 can be determined as follows:
•
on the type label of the electronics
•
Via the display and adjustment module
•
via PACTware
