11.2.2 Standard unit of measurement
u
Select the CFG menu.
u
Select [uni.F] and set the unit of measurement for the flow: l/min, m
3
/h, m/s, ft
3
/min, ft
3
/h, ft/s.
The consumed quantity (meter reading of the totaliser) is automatically displayed in the unit of
measurement providing the highest accuracy.
u
Select [uni.T] and set the unit of measurement for the temperature: °C or °F.
u
Select [uni.P] and set the unit of measurement for the pressure: kPa, bar, psi.
11.3 Setting the output functions
The parameters for flow monitoring, temperature monitoring and pressure monitoring are set in
the same way. The prerequisite is that the process value for OUTx has first been defined via
[SELx].
11.3.1 Limit monitoring OUTx / hysteresis function
u
Select the OUTx menu.
u
Select [oux] and set the switching signal:
•
Hno: hysteresis function / normally open
•
Hnc: hysteresis function / normally closed
u
Select [SPx] and set the measured value at which the output switches.
u
Select [rPx] and set the measured value at which the output switches off.
11.3.2 Limit monitoring OUTx / window function
u
Select the OUTx menu.
u
Select [oux] and set the switching signal:
•
Fno: window function / normally open
•
Fnc: window function / normally closed
u
Select [FHx] and set the upper limit of the window section.
u
Select [FLx] and set the lower limit of the window section.
11.3.3 Analogue signal OUT2
u
Select the OUT2 menu.
u
Select [ou2] and set the function:
I: flow-proportional current signal 4…20 mA.
u
Select [ASP2] and set the measurement value at which the output signal is 4 mA.
u
Select [AEP2] and set the measurement value at which the output signal is 20 mA.
11.3.4 Pulse signal OUTx
u
Select the OUTx menu.
