Replacing the Instrument
To replace an instrument that has been previously
mounted to a control valve, perform the following basic
steps:
Instrument Removal
1. Make sure that the valve is isolated from the
process.
2. Remove the instrument cover (refer to figure 6-1).
3. Disconnect the field wiring from the terminal board.
4. Shut off the instrument air supply and disconnect
the tubing to the supply port.
5. Disconnect the tubing from the output port.
6. Remove the bolts connecting the DVC2000
housing to the mounting bracket.
Note
The magnet assembly may remain on
the valve stem (or shaft).
When replacing the instrument, be sure to follow the
mounting procedure outlined in Section 2. Once the
instrument is mounted, perform the Quick Setup
