The different output types are optimized for different types of applications. The
following table contains the application recommendations for the different output
types. If the outputs are not used according to the recommendations, measurement
deviations can occur and the desired functionality is not achieved.

10.6.1 Alarm
output
The alarm outputs can be parameterized with a limit value function or a window
function.
10.6.1.1 Function
The parameter
"Function"
defines the basic function. Limit value function and
window function are available.
Limit value function: The switching output is
active
if the current flow rate value is
above the switching threshold. It remains
active
until the measured value has fallen
below the switching threshold minus the hysteresis.
Window function: The switching output is
active
if the current flow measured value
is outside a window, which is formed by the
"switching threshold"
and the
"lower
threshold".
The monitored window decreases in each case by the amount of the
"hysteresis"
. If the switching output is to be
active
within the window, the parameter
"switching function"
must be changed from N/O to N/C.
