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.

Terminology

Instrument Level – There are four (4) levels of functionality available: AC, HC, AD and PD.

AC – This level provides the capability to setup and calibrate the positioner through the local

user interface or a handheld communicator.

HC – This level provides additional capability for advanced configuration of the positioner

(such as travel limits/cutoffs, custom characterization and minimum open/closing time).

Also, information is available through the HART protocol for diagnostic alerts such as travel

deviation, cycle count and travel accumulation.

AD – This level provides advanced diagnostic capabilities for performance testing. When used

with ValveLink software, instrument health can be evaluated with tests such as Valve Signature,

step response and dynamic error band. The software program provides detailed analysis

with graphics.

PD – This level provides automated, non-intrusive testing of the operating performance of

the control valve assembly. When used with ValveLink software, tests to isolate component

degradation can be run on the valve assembly without affecting the process.

Local Interface – The DVC2000 comes standard with a Liquid Crystal Display (LCD) and four (4)

pushbuttons. The local interface provides the capability to setup and calibrate the positioner

and view basic diagnostic messages.

Magnet Assembly – This is the feedback component that is mounted directly to the valve stem.

It supplies a magnetic field that is sensed by the digital valve controller.

Options Board – The DVC2000 digital valve controller is available with two (2) limit switches

and a valve position transmitter. The options board includes the additional circuitry and

terminations that are required to support these output signals.

Pole Piece – Inserted into the DVC2000 housing and protruding through the back of the

instrument is a two-pronged fork that houses the magnetic sensor for position feedback.

Instrument Description

The DVC2000 digital valve controller is a communicating, microprocessor-based

current-to-pneumatic valve positioner. It is designed to replace standard pneumatic and

electro-pneumatic valve positioners.

In addition to the traditional function of converting an input current signal (4 to 20 mA) to a

pneumatic output pressure, the DVC2000 digital valve controller communicates via a local

display panel and/or via the HART® protocol. An option is available which provides isolated

circuitry for two (2) integrated limit switches (for open/close valve indication) and a valve

position transmitter (for separate valve position feedback).

Magnet Assembly – This is the feedback component that is mounted directly to the valve stem.

It supplies a magnetic field that is sensed by the digital valve controller.

terminations that are required to support these output signals.

Plug and Play Components. The system power supply assembly fits into any

power slot of any DeltaV power supply/controller carrier.

This not only simplifies system design, but also reduces spare parts inventory through interchangeability.

DIN-Rail Mounting. Power supply installation is simple.

Mount the power supply/controller carrier on the T-shaped DIN rail.

Then plug the system power supply into the carrier.

Internal Power Bus. The power supply/controller carrier contains an internal power bus.

You do not need to use external cables to connect the system power supply

to the DeltaV controller and I/O interface carriers.

Modular power supplies. You know the power requirements for today,

but what about the future? Build a solid foundation now and build on it later.

Modular power architecture allows you to install additional power supplies for controllers and I/O

subsystems.

Precision outputs. System power supplies accept a wide range of power

inputs and convert the inputs into precise power outputs.

Power Redundancy: DeltaV system power supplies can be redundant on a 1-to-N basis, while other

systems are 1-to-1.

This provides an economical solution for creating system redundancy.

Fault Detection. Undervoltage and overvoltage conditions are detected and logged to protect

the controller and I/O subsystems and to automatically cold-start the controller in the event of a high-

capacity power failure.

Standards compliance. The power supply is EMC and CSA compliant.

It is designed to comply with European ‘Power Factor Correction’ standards.

Immediate notification of power failure. The internal relay outputs change state and alert

the user if the input voltage fails or the system power fails.

In addition, an LED on the power supply housing displays the status of the power supply.

System and Field Power Isolation. The system power supply provides isolation

between the system power supply and the field power supply when the system

power supply and the field power supply are powered by the same 24-volt DC bulk power system.

Power Supply Removal. The system power supply is easy to remove/replace.

The bulk power cord connects to an easy-to-install connector instead of screw terminals.

Product Description

The DC/DC System Power Supply is used to power DeltaV controllers and I/O interfaces

from a 12 or 24V DC bulk power supply that can be mounted next to the controller

in the power supply/controller carrier and provides the 5 and 3.3V DC power required by the controller.

It provides 5V and 3.3V DC power for the controller.

It also provides 12 VDC power for the I/O interfaces and up to 8 amps when powered from a 24 VDC bulk

power supply.
