saturated
Check empty pipe
or Galv. Voltage
Signal at the input of the AD converter
exceeds the maximum value of 2.5 V.
No further measurement is possible. If the pipeline is empty, check whether
the empty pipe detection function is
activated.
In the "Diagnostics" menu, activate the
empty pipe detection function.
Check whether the current flowrate
exceeds the configured flow range end
value. If yes, increase Qmax (= flow
range end value).

The noise exceeds the bandwidth set
for noise reduction for a longer period
of time. Switch off noise reduction in the
"Device Setup" menu or contact ABB
Service.

The Flowrate
is set to zero
Check digital in
terminals 81,82
The function of the digital input (DI) is
set to "external output switch-off" and
the digital input (DI) is set to high
signal (+24 VDC). Set the digital input (DI) to low signal (0
VDC).

Simulation Mode
Simulation mode is activated. One of
the following functions is simulated:
Flowrate [%] or flowrate [unit] or flow
velocity.
These readings in simulation mode do
not represent the system conditions. In the "Diagnostics" menu, deactivate
simulation mode.

Fixed Current Output
Simulation Mode?
HART address>0?
The current output is simulated and is
currently set to a specific value.
The error message is displayed if the
HART address is not 0 (HART
multidrop mode, current output set
permanently to 4 mA). Deactivate simulation mode in the
"Process Alarm" menu or set the HART
address to 0 in the "Communication"
menu.
C177.015
Config.
HART Address <>0
Multidrop Mode
Set HART
Addr. = 0
HART address not 0
(HART multidrop mode, current output
set permanently to 4 mA). Set the HART address to 0 in the
"Communication" menu.

Totalizer Stop
Check digital in
terminals 81,82
The function of the digital input (DI) is
set to "external totalizer stop" and the
digital input (DI) is set to high signal
(+24 V DC). Set the digital input (DI) to low signal
(0 V DC).
