Limiting the signal pressure

If the maximum actuator force may cause
damage to the valve, the signal pressure
must be limited. Select Code 3 to enable
configuration and then access Code 16 to
set the pressure limit to 1.4, 2.4 or 3.7 bar.
5.4 Checking the operating
range of the positioner
To check the mechanical attachment and the
