Self-Test Fault

At start-up, and periodically during operation, Morningstar products perform various tests on internal components and circuitry. In the event an issue is detected with a component or circuit, the controller will cease operation and display the appropriate LED combination alerting the user of the failure. Additional, “Self Test Fault” will be displayed on any Morningstar meters connected to the controller. This is done to protect against potential system damage due to failed components.
