Load Sharing Module Manual 26011SYMPTOMS CAUSE TEST/REMEDYLoad Signal voltageis too high. AdjustingLOAD GAIN will notlower it.CT output too high. Check for 5 amp CT output atfull load. (CT output must bebetween 3 and 7 amps at fullload.) Change to a higherprimary current CT if necessary.Engine does notproperly share loadwith other units.Engine does notproperly share loadwith other units.Engine does notproperly share loadwith other units.Engine not respondingto signal from LoadSharing Module.Unequal speedsettings.Unequal load gainvoltages.Improper load sensingphasing.Circulating currentsbetween generators.(Noted by unequalpower factors betweengenerators.)Terminals 13 and 14not shorted. Loadsharing module is indroop.Check for maximum voltagefrom terminals 22 to 23. Ifpossible check the voltage fromterminal 20 to 19. If the LoadSharing Module is putting out amaximum signal, the problem iseither in the wiring to the enginecontrol, the engine control, orthe engine.Be sure the speed settings of alloff-line units at no load areidentical. Adjust as necessary.Resynchronize.Check that load gain settings ofall load sharing units arecorrect. See load gainadjustment in Chapter 4. Adjustas necessary.Perform the transformer phasingcheck in Chapter 4. Correct asnecessary.Properly adjust the generatorvoltage regulators.Jumper Load Sharing Moduleterminals 13 and 14. Observeengine operation. Replacewiring or switch as required.26 Woodward
