PERATING THE PROCESS CONTROLLER
Process actual value from transmitter : 4 ... 20 mA corresponds 0 ... 10 l/min
Process setpoint from SPS: 4 ... 20 mA corresponds 0 ... 8 l/min
Example of scaling for 4 ... 20 mA input:
NOTE
On entering small scaling values, decimal places are automatically added to increase the
precision of display, such that the maximum possible digit range is given between the lower
and upper scaling values in each case. The amplification factor KP of the process controller
refers to the scaling values set.
With P.CO SETP / SETP INT (setpoint entry via the arrow keys), scaling of the setpoint via
SP and SP is not possible. The setpoint may be entered directly corresponding to the
scaled process variable (PV , PV ).
