Manual Speed Override If the ‘Override MPU Fault’ function is assigned to a contact input, the loss-ofspeed detection logic is overridden as long as this contact is closed; until the maximum time expires. Opening the assigned contact input, disables the override logic, and re-arms the loss-of-speed detection circuit. Once re-armed, a system shutdown is executed if the sensed speed drops below the ‘Failed Speed Level’ setting. A maximum override time limit is provided as an extra level of protection, in the event the contact input is left closed. A ten minute maximum time limit is applied to the Manual override command (as defaulted in the Service Mode). This time starts when the RUN command is initiated and re-arms the loss-of-speed detection when the time expires. The 505E will execute a system shutdown if turbine speed is not above the ‘Failed Speed Level’ setting when the time expires. Automatic Speed Override If the Manual Speed Override is not programmed, the Automatic Speed Override logic is used by the 505E to override the loss-of-speed signal shutdown during a turbine startup. With the Automatic Override logic, the loss-of-speed signal failure is armed when the turbine trips and remains armed until the sensed turbine speed exceeds the programmed (‘Failed Speed Level’ setting + 250 rpm). Once turbine speed exceeds this level, the loss of speed detection circuit is re-armed and the control will execute a system shutdown if sensed speed drops below the ‘Failed Speed Level’ setting. For added protection, a time limit is available on the automatic speed override function. The speed override timer deactivates the loss-of-speed override logic after the programmed time expires. If programmed, this timer starts counting down once a ‘RUN’ command has been issued.
This timer when programmed provides an extra level of protection, in the event both speed input probes are failed when the unit is started. This timer may be programmed in the 505E’s Service mode. Turbine Start Modes Manual Start Mode The following startup procedure is employed when the Manual start mode is configured: 1. Issue a RESET command (to reset all alarms and shutdowns) • At this point the 505E will ramp open the LP valve limiter to its maximum position. • If programmed as extraction only, the LP valve position will ramp to the maximum limit until extraction is enabled. • If programmed for any admission, the LP valve position will vary to maintain zero extraction/admission flow. 2. Issue a RUN command (verify T&T valve is closed before issuing) • At this point the 505E will ramp open the HP valve to its maximum position at the ‘HP Valve Limiter Rate’. • The speed setpoint will ramp from zero to the minimum controlling speed setting at the ‘Rate to Min’ rate.
