F application
error
Application-dependent error of the
complete device, device is however
ok.
F open circuit A
(or B, C)
Current on current output A (or B, C)
too low.
Check cable or reduce resistance
(< 1000 Ohm).
F over range A
(or B, C)
Current on current output A (or B, C)
is limited by parameter setting.
Extend upper or lower limit for
current output in menu C2. .8.
F over range A
(or B, D)
Pulse on frequency output A (or B, D)
is limited by parameter setting.
Extend upper or lower limit for
frequency output in menu C2. .7.
F active settings Error during CRC check (Cyclic
Redundancy Check) of the active
settings.
Load settings; factory setting, back
up 1 or back up 2.
F factory settings Error during CRC check of factory
settings.
F back up 1 (or 2)
settings
Error during CRC check of back up
1 (or 2) settings.
Save active settings in back up 1 or
back up 2.
F wiring A (or B) Current of current input is below 0.5
mA or above 23 mA.
Check connection of control input or
current input.
Open or short circuit of control input
A (or B).
F flow exceeding
limit
Over range, the meaured values are
limited by the filter setting.
Limitation fct. C1.3.1, increase
values.
F signal lost path
1 (or 2, 3)
Signal lost on path 1 (or 2,3). Check vacuum, composition of gas or
collection of liquid in transducer
tubes.
F transducer
delay
Invalid on-line measurement of the
transducer delay.
F temperature
input
No temperature data available.
F pressure input No pressure data available.
S out of
specification
Unreliable measurement. Maintenance required, check flow
profile.
S overflow
counter 1
(or 2, 3)
Counter is overflowing and will start
again at zero.
No action needed.
S backplane
invalid
Error during CRC check of
backplane.
Restore data records on backplane.
S error current A
(or B)
Error current at current input A
(or B).
S unreliable 1
(or 2 or 3)
Signal detection of path 1 (or 2 or 3)
is difficult due to excessive noise or
variations in the amplitude of the
received signal. The accuracy is not
guaranteed.
S frontend
calibration
Invalid calibration data of the
frontend.
S dsp timing
error
Ping time of the frontend is too short.
C checks in
progress
Test run of the device, measured
value can be set to simulated
measured values or to a fixed value.
C simulation flow Sensor electronics simulates
measurement of volume flow.
