charging protection interval. After equalized charging is complete, scheduled equalized
charging starts when the non-equalized charging time exceeds Scheduled equalized
charging interval.
Float volt. temp. comp.
Option to correct the float voltage based on the battery temperature when a battery
temperature sensor is connected. The value is configurable in any mode.
Float volt. temp. comp. coef. (mV/° C· cell)
Correction coefficient during float voltage temperature compensation.
Max. batt. dis. time (h)
Set the maximum battery discharge time. When the discharge time reaches the value, the
UPS powers off. The battery discharge time can be set only to 0 hours or a value in the
range 16–48 hours. The default value is 24 hours. If the time is set to 0 hours, battery
discharge protection is not implemented. This parameter cannot be set to a value in the
range 1–15 hours.
Sched. shallow dis. test
When certain conditions are met, the charger shuts down, and batteries supply power to
loads. The system records the battery discharge data as the reference for battery capacity
and lifespan.
Sched. shallow dis. test time
The discharge test starts in the specified time period. The value can be 00:00-06:00
(default), 06:00-12:00, 12:00-18:00, or 18:00-24:00. Sched. shallow dis. test time is
displayed when Sched. shallow dis. test is set to Enable.
Sched. shallow dis. test interval (d)
Set a time interval for shallow discharge tests. The value can be 30-90 days, 60 days by
default. The value is configurable in any mode. Sched. shallow dis. test interval (d) is
displayed when Sched. shallow dis. test is set to Enable.
Shallow dis. test dis. ratio (%)
Set the proportion of the discharge capacity to the total discharge capacity. The value can
be 10%-50%, 20% by default. The value is configurable in any mode.
Undertemp. alarm thresh. (° C) and Overtemp. alarm thresh. (° C)
Battery temperatures can be monitored in a timely manner. If a battery overtemperature
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. The Undertemp. alarm thresh. can be set
from -20° C to +5° C and the default value is –5° C. The Overtemp. alarm thresh. can be
set from 35° C to 55° C and the default value is 50° C.
Backup time warning, Remain. cap. warning, Backup time warn. thresh. (min), and
Remain. cap. warn. thresh. (%)
When the first two parameters are set to Enable, an alarm is generated when the backup
time or remaining capacity is less than the alarm threshold. The backup time alarm
threshold is 3–30 min, and the default value is 5 min. The remaining capacity alarm
threshold is 5%–50%, and the default value is 20%.
Dis. cur. 0.1C EOD (V/cell), Dis. cur. 0.3C EOD (V/cell), Dis. cur. 0.5C EOD (V/cell),
and Dis. cur. 1.0C EOD (V/cell)
By default, 0.1C EOD (V/cell) is set to 1.80, 0.3C EOD (V/cell) to 1.75, 0.5C EOD
(V/cell) to 1.67, and 1.0C EOD (V/cell) to 1.60. These values are calculated in real time
based on the discharge currents.
