9.5.3 Special Notes
The physical signal level for internal analog inputs (AIM) is always 0 ... 10 V (= 0 ... 100%).
For external analog inputs (AIP) the physical signal level can configured within :
– 0 ... 10 V (0 ... 100%)
– 0 ... 20 mA (0 ... 100%)
– 4 ... 20 mA (0 ... 100%)
In the manual operating mode only the relative signal level (0 ... 100 %) for the analog in-
puts is displayed or must be entered. The assignment to the physical value can be derived
from the measurement range of the corresponding process value.
After operation in „manual“ mode all analog inputs must be reset to „auto“. Other-
wise the functions of the DCU3 - system will be restricted.
