Functionality
The station battery supervision function SPVNZBAT is used for monitoring battery
terminal voltage.
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.
