OPERATION / TESTING / MAINTENANCE

OPERATION
When AC power is applied, the LED test switch (LTS) is illuminated, indicating that the batteries are being charged.
When AC power fails, the LVU-2/5 automatically switches to emergency (battery) power, which can be maintained
for >90 minutes, operating the loads specified emergency power level. The LTS is switched off. When AC power is
restored, the LVU-2/5 switches the system back to normal mode and resumes battery charging. The charging time
for the full discharged battery is 24 Hours.
TESTING AND MAINTENANCE
Periodic tests are recommended to ensure the system is functioning normally:
1. Visually inspect the LTS monthly. It should be illuminated when AC power is applied.
2. Conduct a 30 second discharge test by switching off the mains power every month.
3. Conduct a 90 minute discharge test once per year. The loads should be illuminated at least 90 minutes.
AUTO TEST
The LVU-2/5 series has integrated Auto Test functions as follows:
1. Instant Auto Test
When the system is connected and powered on, the LVU-2/5 model will Auto Test to verify proper connection of
LED load and connection/charging of battery pack. In case of LED load or Battery pack problem, the LTS will flash.
When the abnormal condition is corrected, the LTS will stop flashing.
2. Preprogrammed Auto Test
1) The initial monthly Auto Test begins 24 hours to 7 days after initial power up; monthly Auto Tests repeat once
every 30 days.
2) Annual Auto Tests repeat every 52 weeks after initial power up.
- Monthly Auto Test
Monthly Auto Test is executed every 30 days, testing:
(a)Transfer from normal to emergency mode, and the reverse;
(b)Battery charging in normal mode and discharging in emergency mode;
Test time is about 30 seconds.
- Annual Auto Test
Annual Auto Test is executed every 52 weeks after 24 hours full charging, testing:
(a)Transfer from normal to emergency mode, and the reverse;
(b)Emergency operation meets 90 minutes minimum; And battery voltage after 90 minutes emergency operation
is equal or higher than 87.5% of initial voltage.
3) During Auto Test, in case of power failure and cannot be on till the auto test completes, the Auto Test will be
executed again 24 hours after the power has been resumed.
4) If the emergency mode causes the battery discharged completely under the power-off condition, the
Preprogrammed Auto Test will be reset after power has been resumed.
MANUAL TEST
- Press LTS one time to simulate emergency mode.
- Press LTS 2 times within 5 seconds to initiate monthly test. Upon completion of this test, the Monthly auto-test
counter is set to repeat after 30 days.
- Press LTS 3 times within 5 seconds to initiate annual test. Upon completion of this test, the Annual auto-test
counter is set to repeat after 52 weeks.
- During the manual test, press and hold the LTS for longer than 3 seconds or press LTS 3 times to terminate the
test. (The next-occurring preprogrammed Auto Tests – Monthly and Annual -- will remain scheduled).
LED test switch (LTS) INDICATION
- LTS slow flash: In charging
- LTS on: Normal
- LTS off: Power failure
- LTS gradual change: In testing mode
- LTS quick flickering: Abnormal condition - Corrective required
