ABB REG650 User Manual

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.
High level detector
The level detector compares the battery voltage U_BATT with the set value of the
BattVoltHiLim setting. If the value of the U_BATT input exceeds the set value of the
BattVoltHiLim setting, the start signal ST_UHI is activated.
Time delay
When the operate timer has reached the value set by the tDelay setting, the AL_ULOW
and AL_UHI 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 tReset, the operate timer resets and the ST_ULOW and ST_UHI outputs are
deactivated.
