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.

Figure 227: 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 U_BATT with the set value of the
BattVoltLowLim setting. If the value of the U_BATT input drops below the set value
of the BattVoltLowLim setting, the start signal ST_ULOW is activated.
The measured voltage between the battery terminals U_BATT is available through the
Monitored data view.
