• Timeout:
If no button is pressed for 15 s while the parameters are being set, the unit returns to
the operating mode with unchanged values�
9.2 Setting the output signal
9.2.1 Setting the output function
►
Select [OU1] and set the switching function:
[Hno] = hysteresis function / normally open,
[Hnc] = hysteresis function / normally closed,
[Fno] = window function / normally open,
[Fnc] = window function / normally closed�
►
Select [OU2] and set the function:
[Hno] = hysteresis function / normally open,
[Hnc] = hysteresis function / normally closed,
[Fno] = window function / normally open,
[Fnc] = window function / normally closed,
[I] = current signal proportional to the pressure 4…20 mA,
[U] = voltage signal proportional to the pressure 0���10 V�
9.2.2 Setting the switching limits
►
Select [SP1] / [SP2] and set the value at which the output switches�
►
Select [rP1] / [rP2] and set the value at which the output switches back�
rPx is always lower than SPx� The unit only accepts values which are lower
than SPx�
9.2.3 Scaling the analogue value
►
Select [ASP] and set value at which 4 mA / 0 V are output�
►
Select [AEP] and set value at which 20 mA / 10 V are output�
Minimum distance between ASP and AEP = 25 % of the span (scaling
factor 1:4)�
