Clear function: after pressing the "learning button" for 8 times, the LED indicator light will be off and then release, and start to clear all remote control code data in the memory. When the LED indicator light flashes for 7 times and then goes off, it means that the clear function is completed.2. Code matching function: press the "learning button" once, when the LED indicator lights up, it means that the microprocessor enters the code matching state, press the matching wireless remote control button, and when the LED indicator flashes three times, it means that the code matching is successful. (this is one key to code, and the program will automatically assign data bits)3. Code test: after the code is successfully matched, press the relay corresponding to the remote control to make the corresponding function action.Wiring and testingMode selection:Inching function: press the learning key once, and the LED indicator light will flash once. When the LED indicator light is on, press the remote control key a that requires code matching, and the LED indicator light on the control board will flash for three consecutive code matching success, indicating the control relay 1, and then press the same remote control key B, and the LED indicator light on the control board will flash for three consecutive code matching success, indicating the control relay 2.
Self locking function: press the learning key twice, and the LED indicator light will flash once. When the LED indicator light is on, press the remote control key a that requires code matching, and the LED indicator light on the control board will flash for three consecutive code matching successes, indicating the control relay 1, and then press the same remote control key B, and the LED indicator light on the control board will flash for three consecutive code matching successes, indicating the control relay 2.Interlock function: press the learning key 3 times, and the LED indicator light will flash once. When the LED indicator light is on, press the remote control key a that requires code matching, and the LED indicator light on the control board will flash successfully for 3 times, indicating the control relay 1. Then press the same remote control key B, and the LED indicator light on the control board will flash successfully for 3 times, indicating the control relay 2.
