Local Control
This procedure allows the user to manually control the position of the valve (see figure 3‐9). To enter this procedure
from the home screen, press the DOWN (B) arrow key seven times and then press the RIGHT (") arrow key.
If you select ANALOG, you will return to the home screen and the digital valve controller will respond to the loop
current. If you select MANUAL, you will move to the screen that shows the travel setpoint and the actual valve travel.
The UP (Y) and DOWN (B) arrow keys will allow you to change the setpoint and therefore move the valve manually.
To exit the manual mode, use the LEFT (A) arrow key to return to the choice list. Select ANALOG.
Note
When placing the instrument back into ANALOG, the valve will step back to the position commanded by the input current.
