11. Troubleshooting
Please check the following before contacting the repair service:
Case Description / where to check
The system does not
work.
• Check if the protection device is turned off.
• Check if timers have been set.
• Check
• During On-line mode or DRED mode, the system does not work according with user
setting mode.
the remaining battery level.
During the stand-alone
operation, operation
of the load becomes
unstable.
Power supplied from this product is not completely same as the commercial power supply.
At that time, please use it to adjust the dimming level.
Charging stops The batteries are full. (Battery indicator on the Control panel turns off from orange.)
Charging stops
nevertheless battery is
not full.
When battery temperature is low, the maximum amount of charged power is limited for
battery protection.
When battery temperature is too high, charging is limited for battery protection.
Power failure or the protection device for storage battery system may have been turned off.
Check the protection device in the distribution board.
Discharging stops The batteries are empty. (Battery indicator on the Control panel turns off from green.)
Discharging stops
nevertheless battery is
empty.
When battery temperature is too high or low, discharging is limited for battery protection.
During on-line system mode, discharging stops before reaching 0% of remaining battery
level for blackout.
Depending on the batteries condition, the battery might not be able to be discharged down
to 0%.
There is a time period
that is not charging and
discharging.
In order to correct the remaining battery level, charging and discharging operation is
stopped once a day (From 3:00 to 3:30).
