S Sensor
Flow Meas. Out of Spec. The vortex frequency or the
volume flow is out of range.
The real flow is higher or
lower than the indicated
value.
Check the process
conditions.
Low Flow Cutoff Undercut Volume flow is lower than
low flow cutoff (LFC)
Check the low flow cut-off or
the process conditions.
Weak Flow Meas. Signal The vortex signal is too weak
or disturbed.
Check the process
conditions and the
installation situation.
Eliminate external
disturbances. If the
message recurs, contact the
manufacturer.
Pres.Sen.Temp. Out of Spec. Temperature of the internal
pressure sensor out of
specification.
Make sure that the device is
operated within the
permissible temperature
range.
Elec. Temp. Out Of Spec. The electronic temperature
of the sensor module is out
of specification.
S Electronics
Elec. Temp. Out Of Spec. The electronic temperature
of the converter is out of
specification.
Make sure that the device is
operated within the
permissible temperature
range.
S Process
CO Undersaturation The measurement value is
lower than the lower range
value of the current output.
The current output is
saturated and does not
reflect the effective
measuring value.
Check the process
conditions and the lower
current output limit.
CO Oversaturation The measurement value is
higher than the upper range
value of the current output.
The current output is
saturated and does not
reflect the effective
measuring value.
Check the process
conditions and the upper
current output limit.
S Config: Totalizer
Flow Totalizer Overflow The actual value of the flow
counter exceeds its preset
value.
Check the setting of the flow
counter or reset the counter.
Energy Totalizer Overflow The actual value of the
energy counter exceeds its
preset value.
The actual value of the
energy counter exceeds its
preset value.
M Sensor Information
Faulty Sensor Oscillator The sensor oscillator is
working out of range.
Perform a hard reset. If the
message recurs, contact the
manufacturer.
Faulty sensor voltage ref. Reference voltage in sensor
module out of specification.
