Relay functions
If all functions are operating correctly, the relay is energized. The relay is de-
energized as soon as an error or alarm occurs:
"Limit" switch position
The relay is de-energized and the red LED is lit if the limit value is exceeded or
undershot (this depends on the min./max. safety setting).
"Limit+error" switch position
The same function as the "limit" function but in addition: The relay is de-
energized if the flow velocity is greater than the measurable value of the
measuring device of if a device error occurs. The red LED flashes. "Error" has a
higher priority than "limit".
Factory setting

be set in increments of 10%, from 10% to 100%.

Full scale value scaling
Full scale value scaling can be adjusted continuously between 1 and 5 m/s via
this potentiometer.
Full scale setting:
The change from an unlit green LED to a lit green LED indicates that the full
scale value matches the current flow velocity, with the current output set to
20 mA.
