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.
