VEGA VEGAPULS 61 (≥ 2.0.0 - ≤ 3.8) 4 … 20 mA__HART four-wire - Manual (Page 46)

Error Cause Removal
V oltage supply
missing
C heck cables for breaks; repair if
necessary
O perating voltage
too low or load
resistance too
high
C heck, adapt if necessary
C urrent signal
greater than 22 mA
or less than
3.6
mA
O scillator in the
sensor defective
E xchange the instrument or send it in
for repair
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 failure reason and measures taken, the steps
described in chapter "Set up" must be carried out again, if necessary.
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.
