A two-position single-point action controller has been adjusted to minimize cycling and would only be suitable for __________.

🔍 Key Concepts

• Two-position (on-off) control behavior and how it responds to load changes • Effect of cycling (hunting) in a control system and when minimizing it is acceptable • Difference between constant vs. varying load/temperature conditions in control applications

💭 Think About

• In what type of operating condition does an on-off controller, once adjusted to minimize cycling, keep the process variable closest to the set point? • How do frequent load or temperature changes affect an on-off controller that is set up not to cycle much? • Which choice describes a situation where slow, infrequent corrections from the controller will not cause problems?

✅ Before You Answer

• Make sure you understand that two-position single-point action means basic on/off control without proportional or derivative action • Ask yourself under which option tight, fast response to changing conditions is least critical • Eliminate any options that clearly require the controller to handle frequent or large changes in the controlled variable
