Operation principle

The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
The function execution requires that at least one of the function
outputs is connected in configuration.
The operation of the station battery supervision function can be described by using a
module diagram. All the modules in the diagram are explained in the next sections.

The battery rated voltage is set with the RtdBattVolt setting. The value of the
BattVoltLowLim and BattVoltHiLim settings are given in relative per unit to the
RtdBattVolt setting.
It is possible to block the function outputs by the BLOCK input.
