VEGA VEGAFLEX 61 4 … 20 mA_HART four-wire - Manual (Page 38)

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.
T
he indicating and adjustment modules indicates faults via error codes
and text messages. The following table describes the error codes with
status according to NE 107 and gives information on the causes of
failure and their removal:
Status accor-
ding to NE 107 Error code Text message Cause/Rectification
F ailure E 013 no measured value available S ensor in boot phase
no measured value available S ensor does not find an echo, e.g.
due to faulty installation or wrong
parameter adjustment
no measured value available W rong sensor length entered
E 017 A djustment span too small A djustment not within the specifica-
tion. Carry out the adjustment again,
thereby increase the distance bet-
ween min. and max. adjustment
E 036 N o operable software F ailed or interrupted software up-
date/Repeat software update
E 042 H ardware error, electronics defec-
tive
E xchange the instrument or send it
in for repair
E 043 H ardware error, electronics defec-
tive
E xchange 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.
