Appendix A. SVi1000 Theory
Introduction
The SVi1000 provides for reliable operations of control valves with utmost simplicity in setup and
commissioning. It is uniquely equipped with a non-contact travel sensor allowing for accurate
positioning and maintenance free operations. The pneumatic train of the SVi1000 is a dual-stage
amplification system with stainless steel wetted parts for durability. Using HART
FDT-DTM technologies, the Masoneilan SVi1000 positioner provides interoperability with leading
control systems suppliers.
SVi1000 Setups
A typical system setup is shown in Figure 31, General Purpose Installation schematic.
Wiring diagrams are generalized, actual wiring must adhere to electrical installation section of
manual and local electrical codes.
