Generator Set Operator Panel

Operator Panels are included with generator sets and interface engine functions with generator functions. This allows for the engine and generator to be controlled by a single component. Operator panels provide the user with easy to view and use information, generator set controls and alarm and monitoring. Many suppliers offer options to panels such as AC metering and alphanumeric displays.

Single Generator Set Components
Many styles of components are available for generator setup and configuration. Systems can be basic (Figure 1) or complex to include remote monitoring and networking. Below is an example of a basic system’s components:

• Generator Set – Comprised of engine and generator and houses operator panel.
• Operator Panel – Communicates with automatic transfer switch (for starting signal). Controls start, run and monitoring activities for engine and generator.
• Automatic Transfer Switch – Monitors power at switch panel. When a significant drop or loss of power occurs, switch signals generator set operator panel to start engine.
• Switch Panels – Distribute power to various circuits.
• Loss of Power

When main power is lost the following events occur:

1. Automatic transfer switch signals generator set operator panel to start.
2. Operator panel starts the generator set and monitors engine and generator functions.
3. Generator supplies power to switch panels. Emergency power is distributed as designed.
4. When main power is available, automatic transfer switch disconnects generator set and connects to main power grid.
5. Operator panel controls engine run time to allow for cool down.
