8 Maintenance and fault rectification
VEGASON 61 • 4 … 20 mA/HART - four-wire
28778-EN-130417
Error Cause Rectification
Current sig-
nal greater than
22 mA or less
than 3.6 mA
Electronics mod-
ule in the sensor
defective
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
– Sensor in boot phase
– Sensor does not find an echo, e.g.
due to faulty installation or wrong
parameter adjustment
E017 Adjustment span too
small
– Carry out a fresh adjustment and
increase the distance between min.
and max. adjustment
E036 no operable sensor
software
– Carry out a software update or send
instrument for repair
E041 Hardware error, elec-
tronics defective
– 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 settings of the
sensor. These are the options:
•
At the factory by VEGA
•
Or on site by the user
In both cases, the sensor serial number is necessary. The serial num-
bers are stated on the type label of the instrument, inside the housing
or on the delivery note.
Information:
When loading on site, first of all the order data must be downloaded
from the Internet (see operating instructions manual "Electronics
module").
The electronics modules are adapted to the respective sensor and
distinguish also in the signal output or power supply.
8.4 Software update
The software version of VEGASON 61 can be determined as follows:
Error messages via the
display and adjustment
module
Reaction after fault recti-
fication
Sensor serial number
