in order to enable Grid Connect mode. 8 7 6 5 Ground 4 3 GC 2 1 (GC stands for Grid Connect) J12 in the Communications Bay Grid Connect Mode Enable The Capstone 60 is always in the Grid Connect mode of operation. However, in order to enable the Grid Connect mode, the Capstone 60 must be connected to the live grid and the Grid Connect Interlock closed. If the Grid Connect Interlock is open, the system will not accept the command and a “User Connection Error” fault will be registered. Grid Connect Settings Set Power Enter the desired output power level in 0.1 kW increments, omitting the decimal. For 60 kW enter “600” and press the ACCEPT key. The system will PRELIMINARY Grid Connect Setup Configuring for Grid Connect To configure the Capstone 60 for Grid Connect operation it is necessary to enable the Grid Connect Interlock. Grid Connect Interlock The Grid Connect Interlock consists of a pair of 5 volt dry circuit contact terminals. A low resistance closed circuit between these terminals permits Grid Connect operation, opening the circuit disallows Grid Connect operation. The dry circuit contact terminals are found on J12 in the Communications Bay at the rear of the Capstone 60 enclosure. 12 11 Terminals 3 and 5 10 must be connected 9 export power at this level whenever it is in Grid Connect mode. For Grid Connect mode, you may enter the maximum value of 60.0 kW. Over Voltage The system will initiate a shut down if the grid voltage exceeds a user-specified value for a user-specified period of time. The system default is 528 volts for 10 seconds. The voltage may be adjusted from the under voltage setting up to 528 volts, in one volt increments. The time period may be adjusted from 10 seconds down to zero, in 0.01 second increments. Fast Over Voltage The system will cease power export to the grid within 1 msec if any phase voltage swells to 635 VAC for 10 msec. If the grid voltage re-stabilizes within 1 second of the initial event, the system will resume power export. Otherwise, the system will shut down. This value is adjustable from the default 635 VAC down to the over-voltage setting. If adjustments are required, Use the System Settings top-level menu and the Fast Over Voltage sub-menus to enter a new value, in one volt (1V) increments. Under Voltage The system will initiate a shut down if the grid voltage drops below a user-specified value for a user-specified period of time. The system default is 360 volts for 10 seconds. The range is 360 volts up to the over-voltage setting. The voltage may be adjusted in one volt increments in top-level menu Grid Connect, sub-menu 2/8 (Under Voltage). The time period may be adjusted from 10 seconds down to zero, in 0.01 second increments. 511519-001 A5 Configuring the SystemPDF Image | C60 Mech
