Load Sharing Module - Home Mega Global Solution

Manual 26011Load Sharing ModuleLoad Sharing Lines, Droop, and Auxiliary ContactsThe droop contact for selecting droop or isochronous operation is wired in serieswith the circuit breaker auxiliary contact between terminals 13 and 14. When boththe droop contact and circuit breaker auxiliary contact are closed, the LoadSharing Module is in the isochronous load sharing mode. In this mode the internalload-sharing-line relay is energized, the droop signal is disabled, and the loadmatching circuit is connected to the load-sharing lines, permitting isochronous loadsharing.The Load Sharing Module is in the droop mode when EITHER the droop contactor the circuit breaker auxiliary contact is open. If the droop contact is open, theLoad Sharing Module remains in the droop mode even when the circuit breakerauxiliary contact is closed. If droop is not desired when the auxiliary contact isopen, turn the droop potentiometer fully counterclockwise.Use a single pole, single-throw switch with a 0.1 A minimum rating for the “openfor droop” switch.Output to the Engine Speed ControlUse twisted 0.5 mm² (20 AWG) or larger shielded wire to connect the outputsignal from terminals 19, 20, and 21 to the engine speed control. Connect theshield to the closest chassis screw only. Do not connect the shield at the speedcontrol end of the wiring.Synchronization ConnectionsIf an SPM-A synchronizer is used, connect twisted-pair 0.5 mm² (20 AWG) orlarger shielded wire from the synchronizer to terminals 24(+) and 25(–). Tie theshield to the closest chassis screw. Do not connect the shield at the synchronizerend of the wiring.Woodward 11
