When the DISP pin is pressed and a high-to-low transition of the pin is detected, the LED display shows the state-of-charge for LED Hold Time. The state-of-charge can display the RelativeStateOfCharge() or AbsoluteStateOfCharge(), based on the [LEDMODE] setting.
The state-of-charge threshold can be set according to the number of LEDs available. The following table shows an example for data flash setting with 5-LED display.
| State-of-Charge(1) | ||
|---|---|---|
| Current() > 0 | Current() ≤ 0 | |
| LED1 | CHG Thresh 1 to 100% | DSG Thresh 1 to 100% |
| LED2 | CHG Thresh 2 to 100% | DSG Thresh 2 to 100% |
| LED3 | CHG Thresh 3 to 100% | DSG Thresh 3 to 100% |
| LED4 | CHG Thresh 4 to 100% | DSG Thresh 4 to 100% |
| LED5 | CHG Thresh 5 to 100% | DSG Thresh 5 to 100% |
If SOC drops below the flash alarm thresholds in charge or discharge, then the LED display also flashes with LED Flash Period per the CHG Flash Alarm or DSG Flash Alarm settings shown below.
| State-of-Charge | ||
|---|---|---|
| Current() > 0 | Current() ≤ 0 | |
| Flash Alert | 0% to CHG Flash Alarm | 0% to DSG Flash Alarm |
In PERMANENT FAILURE mode the StateOfCharge() display is replaced with the PERMANENT FAILURE mode display with of LED 2 blinking.
If [LEDPF1, LEDPF0] = 0,1, then the LED display shows PF Error Code for LED Hold Time after SOC if DISP is held low for LED Hold Time (default)..
If [LEDPF1, LEDPF0] = 1,1, then the PF Error Code shown after SOC.
