Wartsila Auxiliary Overspeed Test: When Safety Systems Don't Work as Expected | ESM-20 Deep Dive.

When overspeed protection testing doesn't go according to plan, that's when real engineering begins.
In this #ProbeTips deep dive, I walk through testing the ESM-20 overspeed protection on our Wartsila auxiliary engine - but nothing goes as the manual suggests. Early shutdowns, cascading alarms, blown fuses, and system logic that seems to fight our every move.

🔧 WHAT WE COVER:
ESM-20 overspeed protection principles & mandatory testing requirements
Why our first test failed at 383 RPM (hint: no standby lube oil pump)
Speed simulator setup and frequency generation verification
Stop/Shutdown Override switch - retrofit installation and actual function
Engine running vs. engine stopped testing procedures
Real-world troubleshooting when Bus 1 power failed
Speed differential alarms and dual sensor verification

⚠️ KEY LEARNING: The Stop/Shutdown Override isn't what most engineers think. It's designed for starting conditions, not operational safety bypassing.

🎯 WHO THIS IS FOR:
Marine Engineers, ETOs, engine room professionals, maritime students, and anyone working with Wartsila engines and ESM safety systems.
