06 MAX OVERSPD TEST LMT (RPM) dflt=4140.0 (0.0, 32000) Enter the maximum overspeed trip speed setting. This is the overspeed trip setpoint used to test the mechanical overspeed shutdown device. (Must be greater than or equal to the ELEC OVERSPEED TRIP SETPOINT). Note: This menu item was moved here from Service Menu I**Overspeed Test** in revision “G” software or later.

07 USE SELF POWERED ACTUATOR?

 Set to true if the actuator gets its hydraulic power from the turbine. If this value is set TRUE, the shutdown discrete output will still operate, but as the turbine slows down and reaches the MPU Override %, the actuator will ramp open. If the MPU fails and a trip occurs, the SELF PWRED DELAY TIME (SEC) will be used to ramp the valve open. If the turbine speed is decreased from an upstream valve such as the Trip and Throttle Valve or a Control Valve, as the speed reaches the MPU Override % the magnetic pickup failed signal will be overridden. The Actuator will ramp open.
