Description
Float volt. temp. comp.
Enable this feature 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 this value, the UPS powers off. The
battery discharge time can be set only to 0 hours or a value
only in a range of 0–48 hours. If the time is set to 0 hours,
battery discharge protection is not implemented. The
default value is 24 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.
Shallow dis. test dis. ratio
(%)
Set the proportion of the discharge capacity to the total
discharge capacity. The value can be 10%–50%, and is
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 –20º
C to +5º
C and the default value is –5º
C. The
Overtemp. alarm thresh.
can be set from 35º
C to 55º
C
and the default value is 50º
C.
