SPVNZBAT activates the start and alarm outputs when the battery terminal voltage
exceeds the set upper limit or drops below the set lower limit. A time delay for the
overvoltage and undervoltage alarms can be set according to definite time
characteristics.
SPVNZBAT operates after a settable operate time and resets when the battery
undervoltage or overvoltage condition disappears after settable reset time.
