Masoneilan SVi1000 digital valve ositioner 6

Masoneilan SVi1000 Digital Valve Positioner have the following features:
• User-friendly “One-button-one-function” local interface
• Robust, non-contact, shielded magnetic-type travel sensor
• Industrial metal housing
• Universal design for linear and rotary valve applications
• Intrinsically safe
• Integrated diagnostics: Cycle counts, Step Tests, Ramp Tests, as well as system health indicators
• Integrates of Masoneilan SVi1000 Digital Valve Positioner with all major DCSs with full DD, DDL, or DTM support
• Universal label with FM, FMC, ATEX, IEC, CE approvals
• Powerful DTM with a user-friendly interface for commissioning, calibration, tuning, diagnostics, and maintenance
While the SVi1000 DTM and the DD allow you to set Aggressiveness, the pushbuttons do not. In all three methods, however, the Aggressiveness value is inherited from any previously performed tuning (Autotune or manual). Once Aggressiveness and other tuning values are determined, they are stored in NVRAM.

The SVi1000 provides a user define Aggressiveness Level for auto-tuning, the allowable range varies from -9 to +9 where 0 (Zero) is considered normal tuning. The Aggressiveness Level influences stroking speed and over-shoot. A negative value will SLOW stroking speed and help minimized over-shoot. A positive value will INCREASE stroking speed and may add some over-shoot. The recommended value for aggressiveness is 0 for control valves without volume boosters.
