I n Ex applications, the regulations for the wiring of intrinsically safe
circuits must be observed.
? E 013
l
no measured value available
à Sensor in boot phase
à Sensor does not find an echo, e.g. due to faulty installation or
wrong parameter adjustment
? E 017
l A djustment span too small
à Carry out a fresh adjustment and increase the distance
between min. and max. adjustment
? E 036
l
no operable sensor software
à Carry out a software update or send instrument for repair
? E 041, E042, E043
l H
ardware error, electronics defective
à Exchange the instrument or send it in for repair
D epending 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
I f the electronics module is defective, it can be replaced by the user.
I n Ex applications only one instrument and one electronics module with
respective Ex approval may be used.
I f there is no electronics module available on site, one can be ordered
from the VEGA agency serving you.
T he new electronics module must be loaded with the settings of the
sensor. These are the options:
Error messages via the
indicating and adjust-
ment module
Reaction after fault rec-
tification
Sensor serial number
