In this menu item you can activate the relay output and determine its
function as well as the switching points.
When the output of the process values is set, you can choose be-
tween overfill and dry run protection.
The relay outputs of the sensor react accordingly.
You can choose "no" reference value. In this case, the relay output
operates as fail safe relay.

Process value
"No" reference value means that the relay output operates as fail safe
relay.
Caution:
Independent of the selected reference value, the relay will deenergize
in case of failure.
Fig. 33: Set up totalizer
With this function you can activate the totalizer. As a default setting,
the totalizer is deactivated.
You can set material quantity that causes a counting pulse to be
outputted via the digital output (NPN transistor).
The leak volume suppression determines which degree of filling (in
percent) activates the totalizer.
With this you can avoid a continued summation of contamination or
slight buildup on an otherwise empty conveyor belt.
