percentage, quick opening, and custom), trending with ValveLink Solo, and the following alerts: travel deviation;
travel alert high, low, high high, and low low; drive signal; cycle counter; and travel accumulation.
AD
Advanced Diagnostics: Includes all functions listed above plus (with ValveLink software) all offline diagnostic tests
(dynamic error band, drive signal, step response, and valve signature) plus online trending
PD
Performance Diagnostics: Includes all functions listed above plus all Performance Diagnostics online/in‐service
valve testing (valve friction, electronics, and mechanical condition)
ODV
Optimized Digital Valve: Includes all functions listed above plus partial stroke test and lead/lag set point filter
