WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before proceeding
with any Installation procedures:
D Always wear protective clothing, gloves, and eyewear to prevent personal injury or property damage.
D Do not remove or uncouple the actuator from the valve while the valve is still pressurized.
D The valve will need to be locked at its present position. If you cannot safely lock the valve in position until this procedure
is complete, do not proceed with this procedure.
D After the valve has been safely locked in position, disconnect any operating lines providing air pressure, electric power,
or a control signal to the actuator. Be sure the actuator cannot suddenly open or close the valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
Note
The lack of a travel calibration can impact the accuracy of the position feedback. While this does not impact the positioner’s ability
to control the process, it can influence the results of specific diagnostic tests. These tests include: Valve Signature, Dynamic Error
Band, and Step Response.
Block the valve into position either with a handwheel, with a pneumatic bypass arrangement that includes a regulator
and pressure gauge, or by mechanicallylocking the valve. Remove the existing digital valve controller by disconnecting
mounting hardware, being careful NOT to loosen or move the magnetic array that is connected to the valve stem
block. The magnetic array will remain on the valve and its position must remain the same. Install the new DVC6200
over the existing array assembly.
