ESC protection
This receiver has multiple prompt functions such as power-on self-check display, overheating alarm prompt, and low/high voltage alarm prompt.
Self-check display: all car lights will be on for 1S when the receiver is powered on; Overheating alam: When the internal temperature of the ESC is detected to exceed 110°C,motor has no output, all car lights flash promptly, and the normal Output will be restored when the temperature is lower than 70°C
ESC function instructions
- Connect related equipment: Make sure the ESC IS oft before connection. connect the motor with M+ and M-of ESC. Connect the steering servo to the 3Pin intertace marked with “STof ESC(-+S connected correspondingly). Connect the battery with the positive and negative poles of ESC correspondingly.
- Normal boot, identification throttle midpoint: After connecting related equipment as step 1, turn on the radio first, move the throttle trigger to the neutral position. Turm on the switch of ESC at last. The receiver will automatically recognize the battery type when it is powered on again. Then it can run it.
Notes
- The ESC can be run after completing self-inspection (about 3 seconds) if power on, otherwise it cannot be operated normally.
- If there is no power output and the red light of ESC flashes quickly after power on, please check whether the throttle trim of the transmitter is set to the “O
- If the rotation direction is not correct during running, exchange the two wires connecting motor and ESC
- To make sure everything is ok, please turn on the transmitter first and finally turn on the ESC, turn off the ESC first and finally turn off the transmitter. receiver Will automatically recognize the midpoint of the trim throttle after restarting
Note: Please refer to the relevant sections for details about the battery type, drag brake force and running mode of the ESC.
Failsafe
This function is used to protect the safety of the model and the operator when the receiver cannot normally receive the signal from the transmitter and is out of control. The receiver defaults that the throttle channel is fixed to be out of control and enters the brake state. After other channels are out of control, the recever has no signal output. If you set it on the transmitter, it will output according to the set value.
Attention
- Make sure the product is installed and calibrated correctly, failure to do so may result in serious injury.
- Please carefully check each power device and car trame instructions to ensure the power matching is reasonable before use. Avoid damaging power system due to incorrect matching
- Do not let the external temperature of the system exceed 90°C /194°F, because high temperatures will damage the power system.
- Make sure the receiver’s battery is disconnected before turning off the transmitter, failure to do so may lead to unintended operation or loss of control. After use, remember to disconnect the
- battery and the ESC. f the battery isn’t disconnected, the ESC will consume electric energy all the time even it t is oft. twill discharge completely if connect to the battery for a long time, thus resulting in the failure of the battery or the ESC. We are not responsible for any damage caused by this!
- Make sure the receiver is mounted away from motors or any device that emits excessive electrical noise.
- Keep the antenna of the receiver at least lcm away from conductive materials such as carbon or metal.
- Do not power on the receiver during the setup process to prevent loss of control
ESC protection
Low/high voltage alarm: VWhen the receiver enters the low voltage protection, the motor has no output, and all the lights Trash slowly; when the receiver enters the high voltage protection, āl cnanneS nave no output. Al Car lights Flash promptly
Car light control
The car light control is mainly to implement the changeover of lighting states and lighting modes by the setting of the transmitter. This receiver is preset with five modes for controlling model car lights. In each mode, the on/off states of backup lights are consistent; in other words, the backup light is in a high-light state when the model car backs up; otherwise, it is in off state. The turn signal light, headlight, stop light, tail light and fog light have different on/off states as follows: Default mode: In this mode, the turn signal light is in off state regardless of whether the model car turns or not; When braking, the stoplight is in a high-light state, and otherwise, it is in off state; The headlight, taillight and fog light are in off state.
- Mode A: In this mode, the turn signal light is in a slow flashing state when the model car turns; When braking, the stoplight is in a high-light state, and when not braking, it is in a low-light state; The headlight is in a low-light state; The taillight and fog light are in off state.
- Mode B: In this mode, the turn signal light is in a slow flashing state when the model car turns; When braking, the stoplight is in a high-light state, and when not braking, it is in a low-light state; The headlight is in a high-light state; The taillight and fog light are in off state.
- Mode C: In this mode, the turn signal light is in a continuously slow flashing state regardless of whether the model car turns or not; When braking. the stoplight is in a high-light state, and when not braking, it is in a low-light state; The headlight is in a high-light state; The taillight and fog light are in on state.
- Mode D: In this mode, the turn signal light is in a slow flashing state when the model car turns; When braking, the stoplight is in a high-light state, and when not braking, it is in oft state; The headlight is in off state; The taillight and tog light are in on state.
Notes
- Press the CH4 button on the transmitter to switch the working mode, one mode per press (Default Mode, Mode A, Mode B, Mode C and Mode D are Switched in turn);
- Every time the receiver is turned on, the car light control mode is in Default Mode;
- Mode Cis an emergency light working state. In this mode, the left and right turn signal lights flash synchronously and slowly as emergency lights.
