Emerson Fisher™ FIELDVUE™ DVC2000 Digital Valve Controller Detailed Setup

Detailed Setup

The DVC2000 digital valve controller has the capability to communicate via the HART

protocol. This section describes the advanced features that can be accessed with a handheld

communicator. Table 3 lists the default settings for a standard factory configuration. Table 4

provides the actuator information required to setup and calibrate the instrument.

Instrument Mode

You can change the instrument mode by selecting Instrument Mode from the Mode menu or

press the Hot Key and select Instrument Mode.

Instrument Mode allows you to either take the instrument Out Of Service or place it In Service.

Taking the instrument Out Of Service allows you to perform instrument calibration and also

allows you to change setup variables that affect control, provided the calibration/configuration

protection is properly set. See Setting Protection.

Control Mode

You can change the control mode by selecting Control Mode from the Mode menu or press

the Hot Key and select Control Mode.

Control Mode lets you define where the instrument receives its set point. Follow the prompts

on the handheld communicator display to choose one of the following control modes: Analog

or Digital.

Choose Analog if the instrument is to receive its set point over the 4 to 20 mA loop. Normally,

the instrument control mode is Analog.

Choose Digital if the instrument is to receive its set point digitally, via the HART

communications link.

A third mode, Test, is also displayed. Normally, the instrument should not be in the Test

mode. The handheld communicator automatically switches to this mode whenever it needs to

stroke the valve, for example during calibration or stroke valve. However, if you abort from a

procedure where the instrument is in the Test mode, it may remain in this mode. To take the

instrument out of the Test mode, select Control Mode then select either Analog or Digital.
