connected to the selected digital input
-
DI2 – “switch open” - the slide end switch for open condition is wired
to the selected digital input
-
DI3 – “switch close” - the slide end switch for closed condition is
routed to the selected digital input
-
DI4 – “stop v-measurement” - the digital input is used to
block/release the measurement using an external signal such as
flood messages or limit values for measurement start or similar.
Indicated as: 0 l/s, inputs and outputs set will de-energise
>Logic< Toggle between inverse and non-inverse input by pressing >up< or
>down< arrow keys. This means that e. g. slide valve signals can be
configured as being normally closed and cable breaks can be detect-
ed without any problem.
Default setting: not inverted
>Name< The name of a digital input can have up to 3 characters. These names
will be indicated in the main screen and in overview menu; see over-
view menu. Set the names as described in chapter “23.1 Parameter
Menu “Measurement Place””.
Ensure reliable contacting
Please observe that the digital inputs are passive and therefore shall be supplied by an
external 24 V DC power supply. The signal current is 10 mA.
Please ensure reliable conductivity by using relay or end switch contacts made of high
quality material.
23.5 Parameter Menu “Analog Output”
Fig. 23-20 Menu Analog output
Use the >right< or >left< arrow key within this menu to select analog outputs 1…3.
>Function< The selected analog output can be assigned to one certain function.
Choose from:
>Not active< Digital output is without function.
>Flow rate< Output of analog signal which is proportional
to calculated flow volume.
>Level< Output of analog signal which is proportional
to measured filling level.
>Velocity< Output of analog signal which is proportional
to mean flow velocity averaged from meas-
ured individual velocities.
