9.3.2 Setting the switching limits
►
Select [SP1] and set the value at which OUT1 switches�
►
Select [rP1] and set the value at which OUT1 switches back�
rP1 is always lower than SP1� The unit only accepts values which are lower
than SP1�
9.3.3 Scaling the analogue value
►
Set the requested minimum pressure in the system�
►
Press [Mode/Enter] until [tASP] is displayed�
►
Press [Set] and keep the buton pressed�
> The currently set value flashes�
►
Release [Set] when the display stops flashing�
> The new set value is displayed�
►
Press [Mode/Enter] briefly�
> The current system pressure is defined to be the start value for the
analogue signal�
►
Set the requested maximum pressure in the system�
►
Press [Mode/Enter] until [tAEP] is displayed�
►
Press [Set] and keep the buton pressed�
> The currently set value flashes�
►
Release [Set] when the display stops flashing�
> The new set value is displayed�
►
Press [Mode/Enter] briefly�
> The current system pressure is defined to be the end value for the
analogue signal�
ASP / AEP can only be taught within defined limits (→ 12.1 setting ranges). If the
teaching process is carried out at an invalid pressure, [UL] or [OL] is displayed� After
acknowledgement by [Mode/Enter], [Err] flashes, the ASP value / AEP value is not
changed�
As an alternative:
►
Select [ASP] and set measured value at which 4 mA / 0 V are output
(20 mA / 10 V at [OU2] = [InEG] / [UnEG])�
►
Select [AEP] and set measured value at which 20 mA / 10 V are output
(4 mA / 0 V at [OU2] = [InEG] / [UnEG])�
Minimum distance between ASP and AEP = 25 % of the final value of the
measuring range (scaling factor 1:4)�
