4.2 Configuring and Calibrating with SVI3 DTM with Valvue
ValVue is the most complete and easiest to use configuration tool. ValVue is downloaded
from the website (https://valves.bakerhughes.com/resource-center) and provides an
interface for configuring and calibrating SVI3. Use of these tools is recommended. See
the See the SVI3 DTM Instruction Manual for the best instructions on how to configure,
calibrate, and use the advanced diagnostics features of the SVI3.
4.3 Local Interfaces and Configurations
This section covers the optional local interface consisting of the LCD graphical display and
pushbuttons. Operation of the SVI3 Digital Valve Positioner as a local device is controlled
through the optional device-mounted pushbuttons and digital display
,
shown in Figure 29
on page 53. Using the display you can read the input signal, valve position, and actuator
pressure and also be notified of faults/alerts within the device.
Using the pushbuttons you can exit from operating mode at any time and step through a
menu structure to perform a wide range of manual operation, calibration, configuration,
and monitoring functions that are described later in this section. ValVue is used to perform
all diagnostics functions. The pushbuttons do not support diagnostics functions.
The SVI3 has two operational modes: Normal (normal operating mode) and Manual
(manual operating mode). In Manual mode, Setup sub-menu can be used, to perform
calibration and configuration activities
.
The SVI3 also has two modes for handling of faults
and power-up: Reset and Failsafe.
The SVI3 has an additional function called
Smart Cal
.
This function is available using the
Smart Cal
/
Back
button on the unit’s front. Smart Cal configures the unit with an optimal set
of operating parameters based on the valve and system configuration.
