    Alarm Delay - the time delay between the detection of the alarm condition and the initiation and indication of the output action. Glossary Alarm Inhibit - prevents low setpoint alarm activation during cold startup applications. Autotuning - “Autotuning” or “self-tuning” simplifies process control by determining the tuning parameters based on an automated analysis of the controlled process’s behavior.
  • Page 47 Lowest Reading - records the lowest process value read by the controller. May be reset to zero by using the Raise or Lower arrow keys. Lower Setpoint Limit - prohibits users from adjusting the setpoint lower than the selected value.
