Manual 26011AppendixLSM Control SpecificationsLoad Sharing ModulePOWER SUPPLYINPUTS3-phase PT InputsPower to operate Load Sharing Module circuitry isobtained from the PT connections. Selectable by jumperfor 95 to 130 Vac or 190 to 260 Vac operation.Approximately 10 W.100–120 or 200–240 Vac line-to-line, 50–400 Hz. PTinput burden is 1.6 W per phase at 240 Vac, 0.4 W perphase at 120 Vac.3-phase CT Inputs 3–7 Arms at full load, CT input burden at full load is 0.1VA per phase.Load Sharing InputSync InputDroop SwitchOUTPUTSLoad SignalAnalog OutputADJUSTMENTSDroopLoad Gain0–3 Vdc into 25 k impedance in isochronous mode,open circuit in droop mode.Compatible with optional Woodward SPM-ASynchronizer, 0.5% speed change* per volt input.The external droop switch is to be wired in series withthe auxiliary circuit breaker contact between terminals13 and 14. Droop mode is selected when either thedroop switch or the auxiliary circuit breaker is open.DC signal proportional to total real current measured bythe Load Sharing Module. Load Gain adjustable overminimum range of 0.86 to 2.0 Vdc/Arms.Minimum dc output range: –4.5 to +1.5 VdcZero error output = +0.0±0.05 Vdc.Provides 0 to 10% speed reduction* between no loadand full load conditions.Provides adjustment of the load on an individualgenerator when two or more generators are paralleled.Adjusts specified full load condition from 3 to 7 Arms.Woodward 35
