4.4.12 Set-up the current output
Menu
The current output is for transmitting the control unit PV value (D800) as a 4–20 mA
signal. The output is calculated by using the range values of parameters P400 and P401.
Consider a control unit PV value of 5 meters and the PV range is 0 to 10 meters:
• 0 meters is represented by a 4 mA signal (0%)
• 5 meters is represented by a 12 mA signal (50%)
• 10 meters is represented by 20 mA signal (100%)
Therefore, the Current Output would output the PV value five meters as a 12 mA signal.
Note
The current output is frozen while the control unit is in the program operating mode.
