4.3 Pressure monitoring / analogue function
The analogue output can be configured�
• [OU2] defines whether the set measuring range is provided as 4���20 mA
([OU2] = [I]) or as 20���4 mA ([OU2] = [InEG])�
Scaling can be set by means of the teaching process or by entering a value for the
ASP and AEP parameters�
• Teaching the analogue start point [tASP] or setting the parameter [ASP] defines
at which measured value the output signal is 4 mA (20 mA at [InEG])�
• Teaching the analogue end point [tAEP] or setting the parameter [AEP] defines
at which measured value the output signal is 20 mA (4 mA at [InEG])�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the
measuring range�
Factory setting
Measuring range scaled
P = system pressure , MAW = initial value of the measuring range, MEW = final value of
the measuring range
1
: [OU2] = [I];
2
: [OU2] = [InEG]
In the set measuring range the output signal is between 4 and 20 mA ([OU2] = [I])
or between 20 and 4 mA ([OU2] = [InEG])�
It is also indicated:
• System pressure above the measuring range:
-Output signal 20 to 20�5 mA at [OU2] = [I]�
-Output signal 4 to 3�8 mA at [OU2] = [InEG]�
• System pressure below the measuring range:
-Output signal 4 to 3�8 mA at [OU2] = [I]�
-Output signal 20 to 20�5 mA at [OU2] = [InEG]�
