The max. flow that the pulse output can work with will be displayed now. This value is cal-
culated from the entered pulse value and pulse width.
If the flow exceeds this value, the pulse output will not function properly. In this case,
pulse value and pulse width have to be adapted to the flow conditions. Press ENTER.
18.5 Activation of an Alarm Output
Max. 3 alarm outputs R1, R2, R3 per channel operating independently of each other can
be configured. The alarm outputs can be used to output information on the current mea-
surement or to start and stop pumps, motors, etc.
