DVC2000 Digital Valve Controller
July 2009
3-12
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
(
) 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 (
) and DOWN ( ) arrow
keys will allow you to change the setpoint and
therefore move the valve manually. To exit the manual
mode, use the LEFT (
) 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.
