29.2 Parameter Menu “Velocity”
Fig. 29-6
Installation direction
>Install. direction<
Installation position is set to “positive” per default.
This parameter should not be modified.
It is going to be used only for special applications where the flow ve-
locity sensor is heading upstream (unlike heading downstream to-
wards the flow direction as in standard applications) but is to detect
positive velocities however. This is the only case which requires set-
ting “negative” here.
29.3 Parameter menu “Digital Input”
Fig. 29-7
Digital input – function – not active
The NFP comes with one digital input (digital input 1, see Clamp wiring Fig. 20-3) to release
the flow velocity measurement (stop v-measurement) or to switch over between operation
modes (measurement ctrl.).
Both functions are required only in exceptional cases and hence shall be used by the NIVUS
commissioning service or authorised persons only.
The digital input is not activated per default.
