9 Diagnosis, Asset Management and service
VEGAPULS SR 68 • 4 … 20 mA/HART two-wire
38294-EN-130624
Maintenance:
Due to external influences, the instrument function
is limited. The measurement is affected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
The following table shows the error codes in the status message
"
Failure
" and gives information on the reason and rectification. Keep
in mind that some information is only valid with four-wire instruments.

F013
no measured
value avail-
able
– Sensor does not detect an
echo during operation
– Antenna system contami-
nated or defective

– Clean or exchange process
component or antenna
F017
Adjustment
span too small
– Adjustment not within
specification
– Change adjustment accord-
ing to the limit values (dif-
ference between min. and
max. ≥ 10 mm)
F025
Error in the
linearization
table
– Index markers are not con-
tinuously rising, for examle
unlogical value pairs
– Check linearization table
– Delete table/Create new
F036

software
– Failed or interrupted soft-
ware update
– Repeat software update
– Check electronics version
– Exchanging the electronics
– Send instrument for repair
F040
Error in the
electronics
– Hardware defect
– Exchanging the electronics
– Send instrument for repair
F080
– General software error
– Separate operating voltage
briefly
F105
Determine
measured
value
– The instrument is still in the
start phase, the measured
value could not yet be
determined
– Wait for the end of the
switch-on phase
– Duration depending on
the version and parameter
adjustment up to approxi-
mately 3 min.
F113
Communica-
tion error
– EMC interferences
– Transmission error with the
external communication
with 4-wire power supply
unit
– Remove EMC influences
– Exchange 4-wire power
supply unit or electronics
F125
Unpermissi-
ble electronics
temperature
– Temperature of the elec-
tronics in the non-specified
section
– Check ambient temperature
– Isolate electronics
– Use instrument with higher
temperature range
