protective devices

Protection devices and emergency stop devices are provided for protection of the generator against trouble during operation. The alarm LED on the digital controller lights or flashes when a fault is detected.

When a major fault is detected, such as low oil pressure, high water temperature, and overspeed, the engine automatically shuts down. Check the display for the fault and correct the problem.

For minor faults, the engine will continue working. Stop the engine and remedy the cause of the problem.

Before inspecting or troubleshooting the generator, press the OFF button on the Digital Controller. Place all circuit breakers in the OFF position and allow sufficient time for adequate cooling.

After automatic shutdown, always inspect the generator and eliminate any problems that might have caused the shutdown before attempting to restart the generator.

When ready to restart the generator, make sure all circuit breakers are OFF. Also check and make sure that the OFF button on the Digital Controller has been pressed to clear the system and that the OFF LED on the Digital Controller is RED. Restart the generator as outlined in the Startup section of this manual.

Refer to the MEC20 Microprocessor Engine/Generator Controller Manual for detailed information of faults and display information.
