OPERATION / TESTING / MAINTENANCE
OPERATION
When AC power is applied, the LED test switch is illuminated, indicating that the batteries are being charged. When
AC power fails, the LVU-2/5 automatically switches to emergency power, operating the LED loads at rated power.
The LED test switch is switched off. When the AC power is restored the emergency module switches the system
back to normal mode and resumes battery charging. The minimum emergency operation time is 90 minutes. The
charging time for the fully discharged battery is 24 Hours.
TESTING AND MAINTENANCE
Following periodical tests are recommended to ensure the system is working well:
1. Visually inspect the LED test switch(LTS) monthly. It should be illuminated when AC power is applied.
2. Conduct a 30 seconds discharge test by switching off the mains power every month. The LTS is switched off .
3. Conduct a 90 minutes discharge test once a year.
AUTO TEST
The LVU-2/5 series has Auto Test function which save the cost of manually maintenance.
1. Instant Auto Test
When the system is connected and powered on, the LVU-2/5 model will Auto Test if the load and battery
pack are connected properly and if the battery is being charged normally. If there is any abnormal situation, the
LTS will flicker. When the abnormity is removed, the LTS indicates normally.
2. Preprogrammed scheduled Auto Test
1) Carry out first monthly Auto Test after Initial power on from 24 hours to 7 days, afterwards, carry out a
monthly Auto Test every 30 days.
2) Carry out an annual Auto Test every 52 weeks after first powered on.
3) Monthly Auto Test
Monthly Auto Test should be executed every 30 days and to test:
If the switchover of normal and emergency mode is normal;
If the emergency function and battery's charging and discharging condition is normal;
Auto Test time is about 30 seconds.
4) Annual Auto Test
Annual Auto Test will be executed every 52 weeks after 24 hours full charging and to test:
If the battery's voltage is equal or higher than the limit after 24 hours full charging;
If the emergency operation time is over 90 minutes;
If the battery voltage after 90 minutes emergency operation is equal or higher than 87.5% of the initial voltage.
5) During the Auto Test, in case a power failure happens and the power cannot be on till the Auto Test completes,
then the Auto Test will be executed again 24 hours later after the power is on.
6) If the emergency mode makes the battery discharged completely under the power off condition, then the
preprogrammed scheduled Auto Test will resume the first time when the power is connected.
MANUAL TEST
- Press LTS one time, the unit will transfer into emergency mode.
- Press LTS 2 times continuously within 5 seconds, the unit will enter monthly test. When complete, the next monthly
test will start counting from this date.
- Press LTS 3 times continuously within 5 seconds, the unit will enter on annual test, when complete, the next annual
test will start counting from this date.
- During the manual test, press LTS greater than 3 seconds, and the manual test will terminate (The preprogrammed
scheduled Auto Test time will not change).
LED test switch(LTS) INDICATION
- LTS slow flash: In charging
- LTS on: Battery fully charged (normal operation)
- LTS off: Power failure
- LTS gradual change: In testing
- LTS quick flickering: Abnormal
