A ‘RUN’ command may be issued from the 505E keypad, an external contact, or through Modbus communications. If an ‘External Run’ contact is programmed, a ‘RUN’ command is issued when the contact is closed. If the contact is closed prior to start-up it must be opened and re-closed to issue a ‘RUN’ command. If turbine speed is sensed when a ‘RUN’ command is issued, the control will instantly match the speed setpoint to the sensed speed and continue towards the minimum controlling speed. In the event the sensed turbine speed is greater than the minimum controlling speed setting, the speed setpoint will match this sensed speed, the Speed PID will control at this point, and the control will wait for further action to be taken by the operator (unless auto start sequence is configured). If the turbine speed is first sensed within a critical speed avoidance band when ‘Run’ is selected, the speed setpoint will match the actual speed and increase to the upper-end of the critical avoidance band and wait for action to be taken by the operator. Start Permissive An external contact may be used as a turbine startup permissive. When programmed for this functionality, the contact input must be closed in order for a ‘RUN’ command to be executed. Should the contact be open when a ‘RUN’ command is given, an alarm will be issued and the 505E display will indicate that the start permissive was not met (Start Perm Not Met). The alarm does not need to be cleared but the contact must be closed before the 505E will accept a ‘RUN’ command. After a ‘RUN’ command has been accepted, the start permissive contact will have no effect on operation. If used, this input is typically connected to a Trip & Throttle valve’s closed limit switch to verify that it is in the closed position before a turbine startup is performed.
Zero Speed Signal Override The 505E issues a shutdown if no speed signal is detected ( i.e. magnetic pickup voltage less than 1Vrms or speed is less than the ‘Failed Speed Level’). To allow the control to start with speed not being sensed, this shutdown logic must be overridden. The control can be configured to provide a manual or an automatic speed override. For added protection, a timed limit on the override is available. The status of the MPU override logic may be viewed in the Service mode or through Modbus communications. The override logic applies to both passive and active speed probes.
