Code Explanation
E011 Device configuration is incorrect
E012 Measurement error or medium temperature outside the
measurable range
E013 Sensor heating defective
E019 Power supply out of specification
E015
E020
Memory error
E021
E022 Power is only supplied to the device via the communication
interface (measurement is disabled)
E042 Output current can no longer be generated (only for
4 to 20 mA output, e.g. load too high at analog output or open
analog output)
Code
Explanation
W107 Simulation active
W200 Medium temperature out of specification (>85 °C)
W202 Measured flow outside the range between the set Low and
High Flow (< –10% or >110%)
W209 Device starting up
W210 Configuration changed (warning code is displayed for approx.
15 s))
W240 Flow velocity too high (> 3 m/sin water), the device is being
operated outside its specified measuring range. The
measurement is uncertain.
W250 Number of max. switching cycles exceeded
W260 Values for High Flow (HIF) and Low Flow (LOWF) are too
close together
W270 Short-circuit and overload at output 1
W280 Short-circuit and overload at output 2
W432 Values for High Flow (HIF) or Low Flow (LOWF) could not be
determined with certainty. The device can still be operated,
however. → 17
28
Flowphant T DTT31, DTT35
Remedy
Perform device reset → 25
Check the medium temperature; return the
device to the manufacturer if necessary
Return device to manufacturer
Check operating voltage
Return device to manufacturer
Check operating voltage
Check load; switch off analog output
Remedy
Check the medium temperature and adapt it
to the specification if necessary
Set the High and Low Flow again; reset the
device to the factory default setting if
necessary (PRES function)
Reduce the flow velocity of the medium
Set the High and Low Flow again (values are
further apart); reset the device to the factory
default setting if necessary (PRES function)
Check output wiring
Check output wiring
Set the High and Low Flow again (keep flow
velocity constant!)
