Engine Overspeed Shutdown

🚨CRITICAL

The engine has exceeded maximum speed and the ComAp controller has initiated an emergency shutdown. Overspeed protection prevents catastrophic engine damage from mechanical failure due to excessive rotational forces.

🔍 Possible Causes

  • •Governor actuator failure
  • •Governor linkage disconnected
  • •Fuel rack stuck in full fuel position
  • •Sudden load rejection
  • •Electronic governor control failure
  • •Speed sensor signal interference

🔧 Troubleshooting Steps

  1. 1Review event log for conditions leading to overspeed
  2. 2Check if caused by load rejection event
  3. 3Inspect governor actuator operation
  4. 4Verify fuel control linkage moves freely
  5. 5Test governor response with InteliConfig
  6. 6Check for speed sensor wiring issues

❓ Frequently Asked Questions

What RPM triggers ComAp overspeed shutdown?

Default overspeed is typically 115% of rated speed - 1725 RPM for a 50Hz 1500 RPM engine. This is configurable but should not be set higher than engine manufacturer limits.

My generator overspeed when load is removed - why?

This is load rejection overspeed. When large loads disconnect suddenly, the engine accelerates. A properly tuned governor should control this within limits.
