The battery rated voltage is set with the
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
setting. If the value of the U_BATT input drops below the set value of the
the start signal ST_ULOW is activated.
The measured voltage between the battery terminals U_BATT is available through the Monitored
data view.
High level detector
The level detector compares the battery voltage U_BATT with the set value of the
setting. If the value of the U_BATT input exceeds the set value of the
start signal ST_UHI is activated.
Time delay
When the operate timer has reached the value set by the
outputs are activated. If the voltage returns to the normal value before the module operates, the
reset timer is activated. If the reset timer reaches the value set by
and the ST_ULOW and ST_UHI outputs are deactivated.
