9.3.2 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 are output (20 mA
at [OU2] = [InEG])�
►
Select [AEP] and set measured value at which 20 mA are output (4 mA
at [OU2] = [InEG])�
Minimum distance between ASP and AEP = 25 % of the final value of the
measuring range (scaling factor 1:4)�
