Poor Controller Tuning.
Operator interventions and Mode Changes are often viewed negatively. When a PID loop is switched out of automatic there can be a sense that the controller wasn’t allowed to perform its job. With each change, goals related to production throughput and efficiency suffer a psychological hit. Since so much is invested in automating plant-wide production, interventions can feel like a step backwards. Viewed in a different light, however, those interventions provide potentially valuable insights that help production to move forward.
