DVC6200 Digital Valve Controllers

January 2014

Step 1—Install the DVC6200 on the Valve

If ordered as part of a control valve assembly, the factory will mount the digital valve controller on the actuator and

calibrate the instrument. If you purchased the digital valve controller separately, you will need a mounting kit. The

following procedures are general guidelines. See the instructions that come with the mounting kit for detailed

information on mounting the digital valve controller to a specific actuator model.

CAUTION

The magnet assembly 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 assemblies.

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. Technicians should

avoid the use of high power magnets in close proximity with any positioner.

Use of Magnetic Tools with the DVC6200

D Magnetic Tip Screw Drivers – Magnetic tip screw drivers can be used to work on the DVC6200. However, they should

not be brought in close proximity to the magnet assembly (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 DVC6200.

Note

The mounting instructions also apply to the DVC6215 remote mount feedback unit.

As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will

decrease as the assembly is increasingly subranged.

The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall

sensor (the center point of the channel on the back of the DVC6200 housing) has to remain within this range throughout the

entire valve travel. The linear magnet assemblies are symmetrical. Either end may be up.

The magnet assembly may be referred to as a magnetic array in user interface tools.

Mounting the instrument vertically, with the vent at the bottom of the assembly, or horizontally, with the vent pointing down, is

recommended to allow drainage of moisture that may be introduced via the instrument air supply.
