(Quantity according to P01a .)
The relay is energized if the measured or
calculated value exceeds the value set in
P14 The relay is de-energized if the measured
or calculated value drops below the value set
in P15
P14, P15
At least 20 mm hysteresis must be
set between P14 and P15 .
P14 > P15 – normal operation
P14 < P15 – inverted operation
1 The relay is energized in case of “noECHO.” -
2 The relay is de-energized in case of “noECHO.” -

COUNTER
For open channel flow measurement. (Volume
and dimension according to P01 and P02).
It puts out a 100 ms long pulse per value
defined in P17.
