Voltage & Frequency Setpoints Defines the voltage and frequency limits for
source being acceptable. Source has an anomaly
when measured voltage/frequency goes out of
range drop-out lower/drop-out Upper. Source
becomes acceptable when measured voltage/
frequency goes back in range pick-up lower/
pick-up higher.
