Setting
Description
Range
Minimum value
If the process value falls below the setting
range, the FDN signal is output. The
maximum input (20mA/5V/10V) of the
measured value (terminal 4) is equivalent
to 100%.
9999 No function
Used to set the set point for PID control.
9999 Always 50%
For deviation ramp input, time (Td) required
for providing only the manipulated variable
for the proportional (P) action.
As the differential time increases, greater
response is made to a deviation change.
9999 No differential control.
