Impulse output / flow switch

This output can be configured as the impulse output or the Flow Switch contact.

Impulse output

For complete setting the parameters of impulse output, it is possible to change the logics (polarity) of
the electrical signal (positive/negative), to set the impulse output to which the volumetric counter will
respond (volume run in positive direction, in opposite direction and in both directions) as well as your
own impulse constant, including its indication (imp/L or L/imp).
The impulse width cannot be set freely using an arbitrary value but it is necessary to select a suitable
impulse width from the predefined width menu (by scrolling the predefined values using the  or )
buttons.

Flow switch

For complete setting the parameters of status output, it is possible to change the logics (polarity) of the
electrical signal (positive/negative) and then set to which volume the output will respond (flow in
positive direction, in opposite direction and in both directions) as well as your own switching point value.
The status contact makes it possible to set the amount of hysteresis between Qon and Qoff states.
