8 Maintenance and fault rectification
VEGACAL 67 • Foundation Fieldbus
31760-EN-130917
Error Cause Rectification
Instrument does
not appear during
connection setup
Profibus DP cable
pole-reversed
Check cable and correct, if necessary
Incorrect termi-
nation
Check termination at the beginning
and end points of the bus and termi-
nate, if necessary, according to the
specification
Instrument not
connected to the
segment
Check and correct, if necessary
Error Cause Rectification
E013 no measured val-
ue available
– Short-circuit due to bridging by con-
ductive buildup between process
fitting and electrode
– Remove buildup - if necessary,
mount a protective tube
Shortcircuit in the
probe, e.g. be-
cause of moisture
in the housing
– Remove the electronics module out
of the probe and check the resistor
between the two marked plug con-
nections according to the figure in
paragraph "Check the resistance in
the probe".
– There should be no contact
between any of the connections
(high resistance)
– If there is still a connection -
exchange the instrument or return
it for repair
E017 Adjustment span
too small
Carry out a fresh adjustment and in-
crease the distance between min. and
max. adjustment
E036 no operable sen-
sor software
Carry out a software update or send
instrument for repair
E113 Communication
conflict
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
If the electronics module is defective, it can be replaced by the user.
In Ex applications only one instrument and one electronics module
with respective Ex approval may be used.
If there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.
The new electronics module must be loaded with the order data of the
sensor. These are the options:
•
At the factory by VEGA
Error messages via the
display and adjustment
module
Reaction after fault recti-
fication
Sensor serial number
