Operation principle
The function can be enabled and disabled with the Operation setting. The corresponding
parameter values are Enable and Disable.
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.

Figure 261: Functional module diagram
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.
Low level detector
The level detector compares the battery voltage V_BATT with the set value of the
BattVoltLowLim setting. If the value of the V_BATT input drops below the set value of the
BattVoltLowLim setting, the pickup signal PU_VLOW is activated.
