Verifying that the automatic load sequence timers are OPERABLE l with the setpoint for each sequence timer within + 5 percent of its design setpoint. 11. Verifying that the following diesel generator lockout features l prevent diesel generator starting only when required: a) Engine overspeed b) 86 GA lockout relay e. At least once per 10 years or after any modifications which could affect diesel generator interdependence by starting the diesel generators simultaneously, during shutdown, and verifying that the diesel generators accelerate to at least 900 rpm in less than or equal to 10 seconds. f. At least once per 10 years
