Built-In Starter Logic • • Full-voltage non-reversing (FVNR) • • Full-voltage reversing (FVR) • • Two-speed (TS) • • Wye-delta open transition (WDOT) • • Inverter (I) • • Soft start (SS) By selecting a pre-defined starter, inputs and outputs are automatically assigned
Process Interlocking • Before Motor Start • Ensure all support, safety and process permissives are ready • At start, ride-through for normal process conditions may be applied • Post Motor Start • Ensure that process flow, pressure, temperature or other limits are not in violation • Provide ride-through for intermittent violations
Process Interlocking Examples • ON START • Centrifugal blower/fan no airflow alarm delayed on start up until static and friction head pressure is established against ductwork by using “start override” delay • DURING RUN • Cryogenic fluid flashes at intervals in a positive displacement pump causing cavitation and momentary drop in differential pressure across pump. Differential pressure alarm delayed using”running override.”
