Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 • USA Technical Reference: Grid Connect Operation – Capstone Models C30 and C60/C65 Fast Transfer Mode Capability Integration of fast transfer functionality must be enabled through software settings in the display panel “Grid Connect” menu or by using RS-232 commands. Hardware modifications must also be performed to take advantage of fast transfer functionality. NOTE Effective August 2005, Dual Mode system owners may incorporate a set of software changes in Model C60/C65 v4.4X+ to take advantage of improved transition speed between Stand Alone and Grid Connect modes. For more information on hardware modifications and overall retrofit requirements, refer to “DMC Modifications – Model C60/C65 Fast Transfer Functionality (440123) Work Instructions.” Grid Connect Menu Parameter Description Parameter Value Default RS-232 GC Enable Mode Each time the system attempts to reconnect to the grid, either recovering from a grid fault condition or during a MicroTurbine restart, it will check the GC Enable Mode (Auto/Manual) setting. Auto – If GC Enable Mode is set as Auto, the system will verify the grid is in a non-fault condition for a period determined by the GC Reconnect Delay setting. Once it has been determined that the grid is in good condition, the system will attempt to restart automatically (If Auto Restart has been enabled). Manual – If the GC Enable mode is set to Manual, the system will wait for a user Start command which will make the system transfer to GC operation immediately. 0=Auto 1= Manual Auto GCEMOD GC Reconnect DLY Defines the transition time delay for the system to check the grid reconnection condition before returning control to GC mode. This setting applies only when the GC Enable Mode is set to Auto. Enter
