Repair; Disposal - Endress+Hauser Flowphant T DTT31 Operating Instructions Manual

DTT31, DTT35
Code Explanation
W107 Simulation active
W200 Fluid temperature outside specification
(> 85 °C)
W202 Measured flow rate outside the range between set Low
and High Flow
(< -10% or > 110%)
W209 Device starts
W210 Configuration changed (warning code displayed for
approx. 15 s)
W240 Flow velocity too high (> 3 m/s in water), the device is
operated outside its specified measuring range. The
measurement is uncertain.
W250 Number of max. switch cycles exceeded
W260 Values for High Flow (HIF) and Low Flow (LOWF) too
close
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 (→ Page 16). The
device can be operated however.

Repair

A repair is not planned.
8.3

Disposal

Please pay particular attention to the local disposal regulations of your country. When
disposing, ensure that the materials of the device components are separated and processed
accordingly.
Endress+Hauser
Remedy
Check fluid temperature and, where
necessary, adapt it to the specification
Set High and Low Flow again, reset device
to factory setting where necessary (PRES
function)
Reduce flow velocity of the medium
Set High and Low Flow again (greater
distance apart), reset device to factory
setting where necessary (PRES function)
Check output wiring
Check output wiring
Set High and Low Flow again (keep flow
velocity constant!)
