Droop Switch = The external droop switch is to be wired in series with the auxiliary circuit breaker contact between terminals 13 and 14. Droop mode is selected when either the droop switch or the auxiliary circuit breaker is open.
Load Signal = DC signal proportional to total real current measured by the Load Sharing Module. Load Gain adjustable over minimum range of 0.86 to 2.0 Vdc/Arms.
PWM Output = Pulse width modulated square wave, 500 ± 100 Hz. Zero error output duty cycle + 69.8 ± 2.0 %. Minimum V (hi) + 10.0 Vdc, maximum V (lo) = 0.5 Vdc when driving external 5.1 K load to 13.0 Vdc external pull-up.
Droop = Provides 0 to 9% speed reduction* between no load and full load conditions.
Load Gain = Provides adjustment of the load on an individual generator when two or more generators are paralleled. Adjusts specified full load condition from 3 to 7 Arms.
