act. mA value:
____ mA
Assign a value for y = 0%
Drive the valve to y = 0 %.
The current current value is displayed. You can change
the valve position either manually or by pressing the
arrow keys on the transmitter. Confirm the position for y
= 0 % by pressing the "E" key.
!
Note!
If you cannot change it using the arrow keys, please
check the "Actuators" menu (Field 165) to see if the
relays have been assigned to valve control.
MD6
act. mA value:
____ mA
Assign a value for y = 100%
Drive the valve to y = 100%.
Proceeding as in the previous field.

If you have no experience in setting control
parameters, the defaults
rapid

slow process
are intended as an aid to adapting the controller
behaviour to the process. Select a default and use the
"controller simulation" (see below) to check if these
settings are relevant for your process.
