Description
discharge, equalized charging
starts only after the float charging
time reaches Equalized
charging protection interval.
After equalized charging is
complete, scheduled equalized
charging starts when the
non-equalized charging time
exceeds Scheduled equalized
charging interval.
When batteries are continuously
under float charging or
hibernation, enable forced
equalized charging. When the
forced equalized charging time
reaches the value of this
parameter, batteries
automatically transfer to float
charging mode.
Set the maximum battery
discharge time. When the
discharge time reaches this value,
the UPS powers off. If the time is
set to 0 hours, battery discharge
protection is not implemented.
Battery temperatures can be
monitored in a timely manner. If
a low or high battery temperature
alarm is detected, the charging
current limit decreases to 0.03
CA. Battery charging stops if a
battery overtemperature
protection alarm (when the
temperature reaches the high
temperature threshold plus 3° C)
is generated.
Single batt. float chg. voltage
deviation alarm thres. (%) and
Single batt. dis. voltage
deviation alarm thres. (%) are
used to check whether the cells in
each battery string have the same
charge voltage and discharge
voltage. When a value exceeds
the specified range, an alarm is
generated.
The calculation formula is
(Charge/Discharge voltage –
Average voltage)/Average
voltage x 100%.
