  34. 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

  35. 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.”
