ECO Min, ECO Max, and EMERG Max refer to operational limits of a generator. These parameters are crucial for ensuring that the generator operates efficiently within its designed capacity. Specifically, ECO Min represents the minimum operational level that a generator should run to maintain stability and efficiency, while ECO Max indicates the maximum operational level for regular generation, ensuring that the generator does not exceed its capabilities under normal conditions. EMERG Max, on the other hand, refers to the maximum output a generator can provide during emergency situations, allowing it to respond adequately to peak demands or system contingencies.

Understanding these operational limits is vital for effective power generation and reliable system operation, ensuring that generators are not pushed beyond their capacity which could lead to equipment failure or safety hazards. In essence, these limits are defined to optimize the performance and longevity of the generator while ensuring the safety and reliability of the power grid.
