B&PLUS RCS600 - Identifying and Troubleshooting Abnormalities; LED Display for Error Determination

LED display for determining abnormalities in the power supply unit and charging unit
【caution】 * 1 The battery voltage error is detected only at the start of charging, and the output overvoltage is detected during charging.
* 2 The LED indications for communication errors A to D di󱐯er depending on the unit and type. Please refer to the following.
Charging unit: Communication error Any of the following behaviors (1) to (4) for A to D
① Ready lights up or blinks.
② Ready, Charge, and End LEDs light up repeatedly in sequence.
③ Ready, Charge, and End LEDs light repeatedly in that order, and then the Error LED lights.
④ Ready → Charge LED turns on repeatedly in this order.
Power supply unit: Communication error Any of the following behaviors ① to ④ for A to D
A Gap error: Only the Power LED lights up. Or one of the following behaviors ① to ④
B、Ｃ Head overheat error: Only Power LED turns on.
Ｄ Signal connector disconnection abnormal: Only Power LED lights up.
① Ready lights up or blinks.
② Ready, Charge, and End LEDs light up repeatedly in sequence.
③ Ready, Charge, and End LEDs light repeatedly in that order, and then the Error LED lights.
④ Ready → Charge LED turns on repeatedly in this order.
