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.
Code Explanation Remedy
W107 Simulation active
W200 Fluid temperature outside specification
(> 85 °C) Check fluid temperature and, where
necessary, adapt it to the specifica-
tion
W202 Measured flow rate outside the range between
set Low and High Flow
(< -10% or > 110%) Set High and Low Flow again, reset
device to factory setting where nec-
essary (PRES function)
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 measur-
ing range. The measurement is uncertain. Reduce flow velocity of the medium
W250 Number of max. switch cycles exceeded
W260 Values for High Flow (HIF) and Low Flow
(LOWF) too close Set High and Low Flow again
(greater distance apart), reset device
to factory setting where necessary
(PRES function)
W270 Short-circuit and overload at output 1 Check output wiring
W280 Short-circuit and overload at output 2 Check output wiring
W432 Values for High Flow (HIF) or Low Flow
(LOWF) could not be determined with certainty
(

Page 14). The device can be operated how-
ever.
Set High and Low Flow again (keep
flow velocity constant!)
