Enter the pulse value. The unit of measurement will be displayed according to the current
physical quantity.
When the totalized physical quantity reaches the pulse value, a pulse will be emitted.
Enter the pulse width.
The range of possible pulse widths depends on the specification of the measuring instru-
ment (e.g., counter, PLC) that is to be connected to the output.
The max. flow that the pulse output can work with will be displayed now. This value is calculated on the basis of the en-
tered pulse value and pulse width.
If the flow exceeds this value, the pulse output will not function properly. In this case, the pulse value and the pulse width
have to be adapted to the flow conditions.Press ENTER.

The alarm will switch if the measured value exceeds the upper limit.
The alarm will switch if the measured value falls below the lower limit.
The alarm will switch if the flow direction changes (sign change of measured value).
The alarm will switch if totalizing is activated and the totalizer reaches the limit.
The alarm will switch if a measurement is not possible.
The alarm is switched off.

If the switching condition is not true anymore, the alarm will return to the idle state
after approx. 1 s.
The alarm remains activated even if the switching condition is not true anymore.

The alarm is energized if the switching condition is true and de-energized if idle.
The alarm is de-energized if the switching condition is true and energized if idle.
Note!
If no measurement is made, all alarms will be de-energized, independently of the programmed
switching function.
