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
– Process component or
probe contaminated or
defective
– Check or correct installation
and/or parameter adjust-
ment
– Clean or exchange process
component or probe
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 values of the lineari-
zation table
– Delete/create a new lineari-
zation table
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
F041
Probe loss – Cable probe broken or rod
probe defective
– Check probe and exchange,
if necessary
F080
General soft-
ware error
– General software error – Separate operating voltage
briefly
F105
Measured
value is deter-
mined
– 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 max. 5 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
Failure
