What it does

Sprocket slip detection watches for a drivetrain discrepancy at the drawworks and acts before mechanical damage compounds. It is a protection function, which means a failed card is invisible during normal operation and only matters at the moment you need it. That makes it worth verifying rather than assuming healthy.
