– Status: The battery status is N/A (battery not connected or reversely connected),
Equalized charging, Float charging, Hibernating, or Discharging.
– Capacity: indicates the remaining battery capacity.
– Backup time:
▪ UPS2000-G-15KRTL-01/UPS2000-G-20KRTL-01: estimated battery discharge
time when the batteries are being charged or discharged
▪ UPS2000-G-6KRTS/UPS2000-G-10KRTS/UPS2000-G-15KRTL/UPS2000-
G-20KRTL: estimated battery discharge time when the batteries are being
discharged. N/A is displayed when the batteries are being charged.
2. Batteries in Hibernating state cannot start a shallow discharge test. Choose
Control and Maintain Batteries, and then press Manual Float Charging to
switch the batteries to the
oat charging state. If the batteries hibernate due
to a charger alarm, the batteries can switch between oat charging and
equalized charging only after the alarm is cleared.
Figure G-2 Manual FC for Pos. screen
For the 6 kVA and 10 kVA UPSs, perform manual oat charging, for the 15 kVA and 20 kVA
UPSs, batteries in positive and negative groups are manually switched to
oat charging
respectively.
Step 2 Adjust the discharge ratio for the shallow discharge test.
1. On the Main Menu screen, select Settings and press . The Settings login
screen is displayed. The preset password is 000001. After you enter the correct
password and press , the Settings screen is displayed.
2. Choose Battery Parameters and Shallow Discharge, and adjust the
parameters to
t actual requirements.
Figure G-3 Shallow Discharge screen
Discharge ratio: indicates the percentage of discharge capacity to the total
dischargeable capacity. The parameter can be set to a value between 10%
and 50%, and the default value is 20%. The parameter is
congurable in any
mode. It is recommended that the value of Discharge ratio not exceed 20%
with the load is light. For example, the value can be 10% or 15%.
