Configuring and Calibrating with ValVue
ValVue Lite is the most complete and easiest to use configuration tool. ValVue Lite is
provided with each SVI II AP. ValVue or ValVue Lite provides a personal computer
interface for configuring and calibrating SVI II AP. Use of these tools is recommended.
See the ValVue Instruction Manual on the CD-ROM included with the SVI II AP.
In this section, we recommend a few ValVue Lite steps to checkout and configure a
pre-installed SVI II AP on a control valve.

NOTE
Setting the input current span is unnecessary except for
applications such as split range. Calibration of the input
current sensor requires the use of high accuracy current
standards. The factory settings should only be changed if a
calibration laboratory detects errors.
Never connect ValVue to an SVI II AP that is in
Configuration or Calibration using pushbuttons.
Installation of Cover
The cover of the SVI II AP is a critical component for safety in Hazardous Areas. To
ensure safe operation the flat surfaces of the cover and the housing must be clean and
absolutely free of particles or dents. The O-ring must be securely located in its groove.
Install the cover and tighten all four screws. There must be no gap between the housing
and cover.
