Actual value special display
The Actual value special display parameters are used to convert and display the actual value signal
in a form more informative to the user.
The Actual value special display parameters are available in PID Control Application and Pump and
Fan Control Application:
Par ID Parameter name
ID1033 Actual value special display minimum
ID1034 Actual value special display maximum
ID1035 Actual value special display decimals
ID1036 Actual value special display unit
Example:
The actual value signal sent from a sensor (in mA) represents the amount of waste water pumped
from a tank per second. The signal range is 0(4)...20mA. Instead of receiving the level of the actual
value signal (in mA) on the display, you wish to receive the amount of water pumped in m
then set a value for par. ID1033 to correspond to the minimum signal level (0/4 mA) and another
value for par. ID1034 to correspond to the maximum signal level (20 mA). The number of decimals
needed can be set with par. ID1035 and the unit (m
value signal is then scaled between the set min and max values and displayed in the selected unit.
The following units can be selected (par. ID1036):

NOTE: The maximum number of characters that can be shown on keypad is 4. This means that in
some cases the display of the unit on the keypad does not comply with the standards.
