4.3 Pressure monitoring/ analogue function
The analogue signal can be set�
• [OU2] defines whether the set measuring range is provided as a 4���20 mA
signal ([OU2] = [I]), a 20���4 mA signal ([OU2] = [InEG]), a 0���10 V signal ([OU2]
= [U]) or a 10���0 V signal ([OU2] = [UnEG])�
Scaling can also be set by means of the teaching process or by entering a value
for the ASP and AEP parameters�
• By teaching the analogue start point (tASP) or setting the parameter ASP you
define the measured value at which the output signal is 4 mA / 0 V (20 mA /
10 V at [InEG] / [UnEG])�
• By teaching the analogue end point (tAEP) or setting the parameter AEP you
define the measured value at which the output signal is 20 mA / 10 V (4 mA /
0 V at [InEG] / [UnEG])�
Minimum distance between [ASP] and [AEP] = 25 % of the final value of the
measuring range (turn down 1:4)�

The output signal is between 4 and 20 mA ([OU2] = [I]) or between 20 and 4 mA
([OU2] = [InEG])� It is also indicated:
