CONDUIT CONNECTIONS
The feedback system for the DVC2000 digital valve controller utilizes a magnetic field for true linkage‐less,
non‐contacting position measurement. In order to prevent inadvertent stem movement while the instrument is in
operation, magnetic tools (such as a magnetic‐tipped screwdriver) should not be used.
CAUTION
The magnet material has been specifically chosen to provide a long‐term stable magnetic field. However, as with any
magnet, care must be taken when handling the magnet assembly. Another high powered magnet placed in close proximity
(less than 25 mm) can cause permanent damage. Potential sources of damaging equipment include, but are not limited to:
transformers, DC motors, stacking magnet arrays.
CAUTION
General Guidelines for use of High Power Magnets with Positioners
Use of high power magnets in close proximity to any positioner which is operating a process should be avoided. Regardless
of the positioner model, high power magnets can affect the positioner’s ability to control the valve.
Use of Magnetic Tools with the DVC2000
D Magnetic Tip Screw Drivers – Magnetic tip screw drivers should not be brought in close proximity to the DVC2000 or the
magnetic feedback array (located at the back of the instrument) during process operations.
D Calibrator Strap Magnets
– These are high power magnets used to hold 4-20 ma calibrators.
Normally, these calibrators would not be used while an instrument is controlling the process.
High power magnets should be kept at least 15 cm (6 inches) from the DVC2000.
