10.1Parallel Data Status Line
The top line of the graphical display is used to indicate the following Parallel Data status:
•STANDBY: Indicates no paralleling activity is occurring.
•DEAD BUS CLOSE: Indicates first generator set in system to close to bus.
•SYNCHRONISE: Generator set is synchronising to bus.
•LOAD SHARE: Generator set has closed to bus and is sharing load with other generator sets in system.
•LOAD GOVERN: Generator set closed to bus in parallel with utility (mains).
Figure 10-1Bus Data Sub-menu
BUS Voltage L–L: The BUS voltage Line–to–Line (L1, L2 and L3) is measured between L1 to L2, L2 to L3 and L3 to L1, respectively.
BUS/GEN HZ: BUS/GEN hertz.
BUS/GEN SYNC STATUS: The bottom line of the graphical display is used to indicate the following BUS/GEN Sync status:
•NOT SYNCHRONIZING: Generator set is in service mode that does not allow auto sync feature.
•SYNCHRONIZING: Generator set is synchronising to bus.
•READY TO CLOSE: In manual mode, push circuit breaker close button to close breaker.
•_\_ Button: (Paralleling applications only). Used to open and close the generator set circuit breaker (CB). The symbol indicates if the CB is opened or closed.
Opened _\_, push to close.
Closed _-_, push to open.
With the control panel Off/Manual/Auto switch in the Auto position, the opening and closing of the CB is controlled by the control system software. The CB symbol will indicate an open or closed CB, but the button will be inactive when the control is in Auto.
In the Manual position, the CB must be closed by this button. When manually closed and the CB opens, it must be closed again by using this button. To close the CB, press and hold the button until the symbol indicates a closed CB. (CB close will occur only when set-up conditions allow - dead bus or generator synchronised with bus).
