DVC6200 Digital Valve Controllers

The Zero Point Calibration procedure allows you replace an existing DVC6200 digital valve controller without
performing a travel calibration. This procedure can be used when a situation occurs that requires the partial or
complete replacement of a digital valve controller when part of a valve assembly that does not have a process bypass
or the process cannot be shut down.

WARNING

Personal injury or property damage, caused by unexpected valve movement and an uncontrolled process, could result if
this procedure is attempted when the valve is not 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.

Notes

This procedure should only used for the partial or complete replacement of a digital valve controller when the valve does not have
a bypass or the process cannot be shut down. Do not proceed with this procedure if the valve has a bypass or the process can be
shut down.

This procedure assumes the array was set up properly on the existing DVC6200 and has not been moved or adjusted since setup.

The valve will need to be locked at its present position. This can be accomplished by using a handwheel or other mechanism. If you

cannot safely lock the valve in position until this procedure is complete, do not proceed with this procedure.

™

This procedure requires the use of a 475 Field Communicator, AMS Trex

This procedure can be used to swap a DVC6200 with another DVC6200. You cannot swap a DVC6000 with a DVC6200 using this
procedure. The DVC6200 used to replace the existing digital valve controller must be a new, factory calibrated instrument. This
procedure will not work if a previously installed and calibrated digital valve controller is used.

Device Communicator, or ValveLink™ software.

CAUTION

The touch screen of the 475 Field Communicator or AMS Trex Device Communicator should only be contacted by blunt
items. The use of a sharp instrument can cause damage to the touch screen interface.
