Basic Setup and Calibration

The local operator interface is available on all DVC2000 digital valve controllers. The interface consists of a liquid
crystal display, four pushbuttons, and a switch for position transmitter configuration. The DVC2000 is supplied with
one of three different language packs preinstalled, depending on the firmware revision and ordering option. Language
pack options are shown in table 1. To configure the language, follow the procedure outlined in the Basic Setup section.
The instrument must be powered with at least 8.5 volts and 3.5 mA to operate the local interface. Certain procedures
require up to 20 mA of current.
CAUTION
When accessing the terminals or pushbuttons, proper means of electrostatic discharge protection is required. Failure to
provide appropriate protection can cause the valve to move, resulting in valve/actuator instability.
Status Information
The first (home) screen on the LCD that is displayed after applying power to the instrument contains basic status
information. On an instrument that is calibrated and operating properly, the flow chart in figure 16 shows the available
information by pressing the right (") arrow key.
