This section contains a summary of the errors that can occur when charging the battery.
Fault Identification
When a fault occurs, LED2 (100%), LED3 (75%) and LED4 (50%), shown in Figure 1, will blink at the same time.
Figure 1.
 |
Blinking Frequency | Fault Cause | Solution |
1 | The battery is not connected or the battery voltage is too low | Ensure battery is connected. Do not charge the battery if the voltage is less than 4V. |
2 | Abnormal AC power input (Voltage) | Check AC input cord is connected between charger and AC outlet. Make sure AC plug is tightly secured into the AC outlet. |
3 | Charger High Temperature Protection | The charger will shut down and go into protection mode. Please place the charger into an area with ambient air flow or a cooler place. |
4 | Battery High Temperature Protection | The charger will reduce or even stop charging when the battery temperature exceeds 50°C. Disconnect the charger and wait 15-20 minutes before reconnecting. |
5 | Output Current is too large | Return to the factory for repair. |
6 | Battery Voltage is too high (>28.5V) | Check and assure that the correct output battery voltage is connected. |
7 | Battery Voltage is too low (<17.5V) | Check and assure that the correct output battery voltage is connected. |
