3. Operating Instructions

The S866 display provides various functions and information. Familiarize yourself with the buttons and display areas for optimal use.

Figure 3.1: Detailed diagram of the S866 LCD display panel, labeling buttons and display areas with corresponding functions.

3.1 Button Functions

• + Button: Up button, used to increase values or assist levels.
• Power Button: Power on/off button, also used to switch information.
• - Button: Down button, used to decrease values or assist levels.

3.2 Basic Operations

• Power On/Off: Hold the Power button to power on. Hold it again to power off. If the e-bike is not used for more than 10 minutes, the display will automatically turn off (hibernation mode).
• Normal Interface: Hold the Power button to enter the normal interface.

3.3 Advanced Operations

Figure 3.2: Instructions for operating the S866 LCD display, including headlight control, assist level changes, 6km/h push mode, and multi-function area navigation.

• Headlight Control: Hold the + button to turn on the backlight and headlight simultaneously. Hold the + button again to turn them off.
• Change Assist Level: Press the + or - button to increase or decrease assist levels. Level 1 is the lowest, Level 5 is the highest. Level 0 disables PAS mode. The display returns to the default assist level each time it powers on.
• 6km/h Push Mode: Hold the - button to enter 6km/h push mode, which moves the vehicle forward at a stable speed (approx. 6km/h). This is useful when pushing the vehicle. Release the button to exit this mode.
• Multi-function Area: Press the Power button to switch between different information displayed in the multi-function area: ODO (Odometer), TRIP (Trip Distance), VOL (Voltage), TIME (Ride Time), and back to ODO.

4. Parameter Setting Mode

This is an advanced function. It is advised not to modify parameters unless you fully understand their implications, as incorrect settings can cause malfunction. Please read these instructions carefully before modifying and note down previous parameter values so you can restore them if needed.

Under the normal interface, press the + and - buttons simultaneously to enter parameter setting mode. The first screen shows P01. Press the Power button to switch to the next parameter, and press the + or - buttons to increase or decrease the value of each parameter. Press + and - again to quit this mode.

In this mode, there are a total of 20 parameters (P01-P20):

Figure 4.1: Parameter settings P01-P05 for the S866 LCD display, including backlight brightness, metric change, battery voltage, hibernate mode, and assist levels.

• P01: Backlight brightness (1-lowest, 3-highest)
• P02: Change metric (0: KM; 1: MILE)
• P03: Select battery voltage (24V/36V/48V/60V, 36V by default)
• P04: Hibernate mode time (from 1 to 60 minutes, 0: never enter this mode)
• P05: Total assist levels (0: 3 levels; 1: 5 levels)

Figure 4.2: Parameter settings P06-P10 for the S866 LCD display, including wheel size, magnet number, speed limit, zero start, and driving mode selection.

• P06: Wheel size in inch (step: 0.1)
• P07: Number of magnets for speed calculation (range: 1-255)
• P08: Speed limit (range: 0-100km/h. This value is always in km/h even if the metric changed from km to mile.)
• P09: Zero speed start (0: zero stat; 1: Non zero start - means need to provide vehicle with initial speed then turn throttle will activate motor)
• P10: Driving mode selection (0: Only assist mode; 1: Only electric mode; 2: Both mode)

Figure 4.3: Parameter settings P11-P20 for the S866 LCD display, including assist sensitivity, starting power, disc type, current limit, low voltage protection, ODO reset, cruise mode, speed ratio, assist level 0, and protocol selection.

• P11: Assist sensitivity (range 1-24, sets the delay between pedaling and motor start; smaller value means the motor starts working after less pedal movement)
• P12: Assist starting power (range: 1-5, sets the starting power of the motor; bigger value means higher starting power)
• P13: Assist disc type (5 magnets, 8 magnets, 12 magnets)
• P14: Current limit of controller (range 1-20A, 12A by default)
• P15: Low voltage protection setting of controller
• P16: ODO distance reset (hold + for 5 seconds to reset this value; hold - for 5 seconds to reset factory settings)
• P17: Cruise mode (0: cruise mode disabled; 1: cruise mode enabled; auto-cruise mode or cruise mode enabled by pressing 1 button - controller should be compatible. Auto-cruise mode is enabled automatically by holding the throttle position for several seconds - this function is realized by the controller)
• P18: Speed ratio (range: 50%~150%, used to correct the speed if the user finds it is not accurate)
• P19: Assist level 0 enable/disable (0: with level 0; 1: without level 0)
• P20: Protocol selection (0: NO.2 PROTOCOL; 1: SS PROTOCOL; 2: RESERVED; 3: RESERVED)

5. Maintenance

To ensure the longevity and optimal performance of your S866 LCD Display Meter, follow these maintenance guidelines:

• Cleaning: Wipe the display screen and body with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as they may damage the ABS material or the screen.
• Water Exposure: While the display is IP65 waterproof, avoid submerging it in water or exposing it to high-pressure water jets. Ensure the waterproof connector remains sealed.
• Connection Check: Periodically check all cable connections to ensure they are secure and free from corrosion or damage.
