Parameter: Color: Black Plug: SM/Waterproof Plug Function: power, speed, gear, etc. Material: plastic Weight: about 120g Voltage: 24V/36V/48V/60V Communication Protocol:UART#2 Note:Please check whether the communication agreement is the same before purchasing. P parameter setting: P01: Backlight brightness (1: darkest; 3: brightest) P02: Mileage unit (0: KM; 1: MILE) P03: Voltage level: 24V/36V/48V/60V (default)/36V P04: Sleep time (0: never, other numbers refer to sleep time) Unit: minutes P05: Auxiliary: 0,3 gears 1gear2V, 2gear3V, 3gear 4V1st, 5th gear 1st gear 2V, 2nd gear 2.5V, 3rd gear 3V, 4th gear 3.5V, 4th gear 4V P06: Wheel diameter unit: inch Accuracy: 0.5 P07: Magnet steel number (1-100) P08: Maximum speed limit unit: KM/H P08: Speed limit: the range is 0-50 km/h, 50 means no speed limit. 1. Non-communication state (instrument control): the speed is turned off PWM output Greater than the set speed; automatically turn on the PWM output when the speed is lower than Set the speed, the current speed is (+1km/h); (close the speed limit Booster only.) 2. Communication status (controller control): The drive speed is kept at the set value.Error: +1km/h; (average speed limit of booster and steering gear) Note: The value here is in kilometers. When the unit setting is changed from kilometers to miles, the speed value of the display interface will be automatically converted to the correct value mile. However, the speed limit data set in the menu under the mileage interface will not be converted.It does not match the actual speed limit mileage value. P9: zero start, non-zero start setting, 0: zero start; 1: non-zero start P10: The drive mode is set to 0: boost drive (determine how much power is required by the boost gear output, the switch is invalid at this time). 1: Electric drive (rotate the driver, the booster gear is invalid at this time). 2: Power-assisted drive and electric drive coexist at the same time (zero-start state of electric drive is invalid). P11: Auxiliary sensitivity setting range: 1-24 P12: Boost start intensity setting range: 0-5 P13: Set booster magnet type to 5, 8, 12 magnets P14: Controller current limit setting default 12A range: 1-20A P15: No present P16: ODO reset setting Press and hold the button for 5 seconds to clear ODO Error Code(decimal) E0 Normal E1 Reserved E2 Brake E3 PAS Sensor Failure (riding mark) Not Realized E4 6km/h Cruise E5 Real-Time Cruise E6 Low Battery E7 Motor Failure(Because the LCD display support without Hall or with Hall ,But if Contoller not connector to Motor Hall ,The LCD display Will be show E7,The Motor ,controller and LCD dispay can be together work ,But Only show E7.So we advice your motor with hall.) E8 Throttle Failure E9 Controller Fallure E10 Communications Recelving Fallure(1. Your controller communication protocol is not suitable for this display. 2. Incorrect line order 3. The connector pins are not firm) E11 Communications Sending Failure E12 BMS Communications Fallure E13 Light Failure
