Check cable and correct, if necessary
Incorrect termination
Check termination at the beginning and end points of
the bus and terminate, if necessary, according to the
specification

In Ex applications, the regulations for the wiring of intrinsically safe
circuits must be observed.

E013
no measured value avail-
able
•
Short-circuit due to bridging by conductive buildup
between process fitting and electrode
•
Remove buildup, if necessary, mount a protective
tube
Shortcircuit in the probe,
e.g. because 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 con-
nections (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 increase the distance
between min. and max. adjustment
E036
no operable sensor soft-
ware
Carry out a software update or send instrument for re-
pair
E113
Communication conflict
Exchange the instrument or send it in for repair
9.3 Exchanging the electronics module
If the electronics module is defective, it can be replaced by the user.
In Ex applications, only instruments and electronics modules with ap-
propriate 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
•
Or on site by the user
