12.LED indications

     (Display)

LED No. (from left)

1.                  SPV ON (Continuous glow)

2.                  Mains ON (Continuous  glow when mains input voltage as per Point No. 1)

3.                  Charging (Continuous glow when battery charged); (Blinking when battery getting charge through mains)

4.                  INV ON (Continuous glow either mains is not available or input voltage out of range as per Point No. 1)

5.                  Over load (Continuous glow in short circuit); (Blinking in overload)

6.                  Low battery (Continuous glow when battery voltage reaches as per Point No. 5.5)

13.  Audible Alarm

Low battery : When battery voltage reaches 10.8 ± 0.2 V, Long beep with 2sec delay between beeps

Over load  : Beep sound for 1 minute continuously then Inverter goes to shutdown, again inverter gets ON within 5 sec if load gets reduced

Short circuit  : Long beep continuously till the UPS reset

14. Protections:

Over load

100 + 5% load on UPS

(auto reset if reduce the load within 3 retries - Beep sound for 1 minute continuously then Inverter goes to shutdown, again inverter gets ON within 5 sec., checks for this condition)

Over charge

Protects the battery from overcharging by limiting the charging current & voltage

Short circuit

Shutdown when AC mains is not there and  AC fuse fails when AC mains is available

Thermal shutdown

Above 93 deg. C inside the unit

Battery reverse polarity

Protects the UPS and DC fuses blown on PMB

Battery deep discharge

Protects the battery from deep discharge having cut-off at

10.8±0.2 V DC(per battery)
