Wiring

Reference for Serial connection of LED

System Voltage	Serial connection	Min. Output Voltage	Max. Output Voltage
12V	5～18 LED	15V	60V
4V	10～18 LED	30V	60V

WARNING
Risk of electric shock! The output voltage is higher than the human safety voltage because of the built-in boost LED driver.
The load or controller is damaged if the LED connection number is wrong.

CAUTION
The above LED (1W, 3.3V) is calculated. If the user uses the unconventional LED, the actual LED voltage must be less than the Max. Load Output Voltage.

Connection Order

1. Connect components to the charge controller in the sequence 1 > 2 > 3 , as shown above, and pay much attention to the “+” and “-.” Please don’t connect the fast-acting fuse or breaker during the installation. When disconnecting the system, the order is reversed.
2. Check that the battery LED indicator is ON when you power the controller; otherwise, please refer to chapter 8.
3. Connect a fast-acting fuse in series through battery positive (+) in the circuit. The fast-acting fuse must be 1.25 to 2 times the rated current. The installed distance is within 150mm.

Load self-test function
The load is ON when the controller is powered on for 10 seconds. After 10 seconds, it restores to set working mode.

The default value can be changed according to the user’s requirement.

Time Control
Control the load on/off time by setting the real-time clock.

 Intelligent Power Reduction Mode
When the battery voltage goes lower than the “Reduce Power Start Voltage (adjustable),” the intelligent power reduction mode is enabled. The LED output current is automatically reduced linearly with the battery’s voltage drop. When the battery voltage goes lower than the “Reduce Power End Voltage (adjustable),” the LED output current is 2% of the rated load current. The minimum percentage can be set to 1%. Also, when the battery voltage exceeds “Reduce Power Start Voltage,” the controller exits the intelligent power reduction mode.

CAUTION

• In Light ON/OFF and Light ON/Timer mode, the load is turned on after a 1- minute delay, and the delay time can be set.
• The controller’s real-time clock is an analog clock, valid at power-on and invalid after power-off. When using the time mode, the clock needs to be calibrated by handheld devices. Do not power off the controller after calibration.

Setting Operation

There are two methods to check and set the controller’s parameters:

1. 2.4G Remote Controller—RC11
   This method can realize one-key setting operation which is suitable for bulk quantity products setting or applied in the projects.
2. Super Parameter Programmer—FC02
   NOTE: Please refer to the user manual of handheld device.

① When the battery is over-discharged, the battery indicator is red. The load keeps off before the voltage exceeds the low voltage reconnect voltage (LVR). To judge whether the system is normal, measure the battery voltage to confirm whether it is more than LVRV. If not, restart the controller to detect the load.

WARNING
The LVRV can be set, but it must be done carefully to avoid damaging the battery if the LVRV is set too low.
