s866 lcd display manual quotation

Note: The value here is based on kilometers. When the unit setting is converted from kilometers to miles, the speed value on the display interface will be automatically converted to the correct mile value, but the speed limit value data set in this menu under the mile interface No conversion, it is inconsistent with the actual displayed mile speed limit value;

Note: Due to the upgrade of the company"s products, the displayed content of the product you get may be different from the manual, but it will not affect your normal use.

I am trying to find a manual for this LCD which I bought together with the Brainpower controller. I have the bike running but the speedo only works when the motor is running which is probably due to having no white wire from the hall sensor, I could fit a wheel sensor and connect to the controller but I guess I would have to disable the existing speed read out. I have also found that when I plug anything into the lamp output on the controller I get an error code 8 or 10. Here is what I have on the LCD menu some of which I have worked out:

Measurements and materials The outer shell of the product is ABS, the transparent LCD window is high-hardness acrylic with a hardness value equivalent to tempered glass.

Features: 1. The LCD displays: Trip time, Current speed, Trip distance, Wattage, Average speed, Total distance travelled, Current, Maximum speed reached, Battery voltage, Battery monitor, PAS level, Error codes and Status indicators. 2. The followings settings are available: Backlight brightness, Metric and imperial units, Voltage level, Sleep time, Number of power assist levels, Wheel diameter, Number of motor magnets, Speed limit, Zero start, Drive mode, Boost sensitivity, Boost start strength, Number of PAS magnets, Controller current limit, Controller undervoltage, ODO reset, Walk assist, Cruise control, Speed ratio, 0 gear and Communication protocol 3. Communication protocol: UART

ODO: total distance travelled, DST: trip distance, VOL: battery voltage, TM: trip duration, CUR: operating current, WATT: instantaneous power, error code (see error code table). Depending on P02 parameter value setting, speed is displayed in km or mile. 1.3 Speed display area

AVG: average speed, MAX: maximum speed, CUR: current speed (mph or km/h). The speed signal is taken from the Hall sensors and/or speed sensor in the hub motor and sent to the display via the controller. The display will calculate the speed by wheel diameter and Hall signal/speed sensor data. If a geared hub motor does not have a builtin speed sensor (no white Hall sensor wire), the display will only show speed when the motor is engaged. In that case an external Hall speed sensor can be installed to constantly show the speed, even when coasting. Depending on P02 parameter value setting, speed is displayed in km/h or mph. 1.4 Power assistance / speed limit level area

2. Buttons, display modes and functions 2.1 Powering on/off the display, available modes To turn the display on or off, press and hold the power button

2.2 Display mode description Mode 1: Trip time, Current speed, Trip distance Mode 2: Wattage, Average speed, Total distance travelled Mode 3: Current, Maximum speed reached, Battery voltage The battery monitor and PAS level are visible in all modes. 2.3 PAS and maximum speed level Short press the plus button to increase the power assistance/speed limit level, short press the minus button to decrease the power assistance/speed limit level. Selecting PAS level 0 allows you to temporarily disable PAS/throttle. Note: PAS level 0 is available only when parameter value P19 is set to “0”. 2.4 Lights Long press the plus button to turn on the lights, the light icon the display and the lights will turn on. Long press the plus button lights off.

2.5 Walk assist Walk assist powers the bicycle up to a steady 6 km/h allowing you to walk alongside the bicycle without needing to push. Long press the minus button to activate walk assist, the walk assist icon will be shown on the display. Long press the minus button again to deactivate. Note: This function will only work when parameter value P17 is set to “0”. 4

2.6 Automatic cruise control Cruise control will automatically be engaged when a steady throttle speed is maintained for six seconds. When the cruise control is engaged, the cruise icon will be shown on the display and the throttle does not need to be held in position anymore for the bicycle to maintain the current speed. Note: This function will only work when parameter value P17 is set to “1”. 2.7 Zero start Zero start allows the motor to start accelerating from a complete standstill when using the throttle. Note: The value of parameter P09 needs to be set to “0” to enable zero start. When zero start is disabled the bicycle needs to be moving at a minimum speed of ?? km/h before the throttle can activate the motor. Note: The value of parameter P09 needs to be set to “1” to disable zero start. 3. Settings 3.1 Changing parameters Long press the plus and minus buttons simultaneously to enter parameter setting mode. Short press the power button to cycle through the parameters (P01-P20) (see the parameter list for details). Short press the plus button to increase the parameter value, short press the minus button to decrease the value. After modifying the parameter value, short press the power button to save the parameter value and go to the next parameter. After parameters are modified, long press the plus and minus buttons simultaneously to manually save the parameters and exit parameter setting mode. Alternatively you can wait 8 seconds to automatically save the parameters and exit parameter setting mode. 3.2 Setting a password Long press the plus and minus buttons simultaneously to enter parameter setting mode. Now long press and hold the power and plus buttons simultaneously to enter password setting mode. Use the plus and minus buttons to modify a digit. Short press the power button to go to the next password digit. After the password is modified, long press the power and plus buttons simultaneously to save the password and exit password setting mode. (Note: From now on you will need to enter the password when powering on the display). Long press the plus and minus buttons simultaneously again to manually save parameters, exit parameter setting mode and go back to the normal user interface. Alternatively you can wait 8 seconds to automatically save parameters and exit parameter setting mode.

4. Parameter list P01: Backlight brightness level: 1-3 (3 = max. brightness) P02: Metric / imperial units: 0 = km, 1 = mile P03: Voltage level: 24V, 36V, 48V, 60V, 64V (Default = 36V) P04: Sleep time in minutes: 0-60 (0 = disabled) Note: This function might not work P05: Number of power assist levels: 0 = 3 level mode, 1 = 5 level mode P06: Wheel diameter in inches; accuracy: 0.1; This parameter is needed to display the speed accurately. P07: Number of speed signal magnets inside the motor × motor reduction gear ratio: 1-100; This parameter is needed to align the actual bicycle speed with the max speed setting. For a regular hub motor, enter the number of speed signal magnets inside the motor; For a geared hub motor, multiply the number of speed signal magnets by the gear ratio; number of magnets × gear ratio = input value; Example: number of motor magnets = 20, (reduction) gear ratio = 4.3 Input value = 20×4.3 = 86 P08: Speed limit: 0-100 km/h, 100 means unlimited speed. The value indicates the maximum speed of the bicycle. Example: a value of 25 means that the maximum speed of the bicycle does not exceed 25km/h; the speed is maintained at the set value. Error: ±1 km/h; (both power assist and throttle speed limit) Note: This value is based on metric units (km/h) even when the display is set to imperial units (mph). Note: The P09-P15 menu is only valid when the display has an active data connection with the controller. P09: Zero start: 0 = enabled, 1 = disabled P10: Drive mode: 0 = PAS (1:1) enabled (throttle is disabled) 1 = Throttle enabled (PAS is disabled) 2 = PAS and throttle both enabled P11: PAS sensitivity: 1-24 P12: PAS start strength: 0-5 Note: This function might not work P13: Number of pas magnets: 5, 8, 12 P14: Controller current limit: 1-20A (Default = 12A) P15: Low Voltage Cutoff; accuracy: 0.1 P16: ODO reset. Press and hold the plus button for 5 seconds to reset P17: 0 = Walk assist enabled, 1 = Cruise control enabled P18: Displayed speed adjustment: 50%~150% P19: PAS level 0: 0 = PAS level 0 enabled, 1 = PAS level 0 disabled 6

P20: Communication protocol: 1 = Protocol 2, 2 = Protocol 5S, 3 = Alternate protocol Do not change, leave set to the default value or your S866 display will not be able to communicate with the controller!

5. Error Codes An error code will be shown on the display if there is an error in the electrical function of the bicycle. Error codes are automatically cleared when the problem has been corrected and the bicycle has reached a minimum motor(assisted) speed of 6 km/h. See the table below for error code descriptions.
