12.14.3 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.
In the definite time (DT) mode, SPVNZBAT operates after a predefined operate time
and resets when the battery undervoltage or overvoltage condition disappears after
reset time.
