VEGAPULS SR 68 • 4 … 20 mA/HART - four-wire
38295-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.
Code
Text mes-
sage
Cause Rectification
F013
no measured
value avail-
able
– Sensor does not detect an
echo during operation
– Antenna system contami-
nated or defective
– Check or correct installation
and/or parameter adjust-
ment
– 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
No operable
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
