Protection Features
1. Thermal Self-Protection: When the internal temperature ofthe charger exceeds 75'C, the charging current will reduce automatically. If exceeds 85'C, the charger will shutdown
protectively. When the internal temperature drops, it will resumecharging automatically.
2. Short-circuit Protection: When the charger encounters unexpected short circuit across the output, charging will automatically stop. When fault removes, the charger will re-start in 10 seconds.
3. Reverse Connection Protection: When the battery is polarity reversed, the charger will disconnect the internal circuit and the battery, the charging will stop and avoid been damaged.
4. Input Low-voltage Protection: When the input AC Voltage is lower than 85V, the charger will shutdown protectively and automatically resume working after the voltage is normal again.
Alarms.
Note:
1. R—red G—green
2. “_” denotes one second stop
3. Above LED flashing sequence is one cycle, the LED will flash repeatedly when in fault.
Choice of Charging Curve (curve 1~10)
1.The LED will flash red several times when AC is first connected, then the LED will flash green once. The number of red flashes denotes the present curve. E.g. If the red flashes three times, it means the present curve is curve 3.
2.To choose another curve, please cut off the power supply first, then unpeel the label, pressing the button while connecting the power. If you want to choose curve 3, release the button after the 3rd LED Flash. Now the selected curve (e.g. curve 3) will be recorded in memory. If you want the charger to work with the selected curve (e.g. curve 3), cut off the power and reconnect it.
3. Factory customizes 10 charging curves before delivery according to customer demand. These are 10 combinations of voltage and battery size for the same battery type.
