The shell’s material is ABS. LCD screen is made of imported high hardness acrylic, and the hardness is equal to the tempered glass.

 

2. Working Voltage and Mode of Connection

2.1 Working Voltage: DC24V 36V（Setting of the meter）

48V（According to customers’ requires to customized）

 

2.2 Mode of connection：                                                           

1.       Red Line（D+）:Enter of the power’s plus                                          

2.       Blue Line（DS）：Controller electric door lock

3.       Black Line（GND）：Power’s minus                                                                                                                                    

4.       Green Line（RX）:Received the communication                                             

Yellow Line（TX）：Send the communication 

 

3.1．Function of  Display

Speed display、Battery indicator、Problems prompt、Mileage、Accumulative mileage

3.2．Function of Control and Setting

Power switch control、Wheel diameter setting、Automatic dormancy time setting、

Backlight brightness setting、startup mode、 drive mode is set、voltage grade setting、controller set current limiting values

3.3．Communication Protocol：UART

All The Content On The Display Screen(Opened In One Second)

   

   

First,Introduce of Display Content

Rapid reverse(FAS), medium speed gear mids(MID), slow(SLO)

Unit: MPH, KM/H

Speed signals according from the motor hall,the controller sends to the display，

(single Hall cycle, Unit： 1MS )

The meter could calculate true speed according to the data of wheel diameter and the signal’s data (electric motor’s Hall need to set up the magnet steel’s quantities)

8. Set

P01：Backlight lamp brightness, level 1 is the most dark, level 3 is the brightest;

P02：Unit mileage, 0: KM;1: the MILE;

P03：Level of voltage: 24 v, 36 v, 48 v, 36 v (by default);

P04：Sleep time: 0, means don't sleep;Other Numbers means for the sleep time,

      range: 1-60;Units of minutes;

P06：Wheel diameter: unit, inch;Accuracy: 0.1;

P07：Speed measuring magnetic steel number: range: 1-100;

P09：Zero start, non-zero start setting, 0:0 start;1: the non-zero start;

P12:  Start strength. Range: 0-5. 0 is the weakest, 5 is the strongest.

P14：Controller for the current limit value to set,12A(by default) range: 10- 20 A.

Note: the part of the parameter is set, the shutdown restart to take effect

 

4.1the shutdown state, short press the ON/OFF key boot, boot, short press the ON/OFF key, interface in the ODO, TRIP, RM, TM, ERRO, switching between

4.2 boot MODE, long press ON/OFF button to turn it OFF, short press MODE key switch SLO, FAS

4.3long press ON/OFF button to enter MODE, in the setup interface, short press the ON/OFF switch parameters;

 

Parameter values change:

Method One: in the condition of a certain parameter, long press ON/OFF button set numerical twinkle,

twinkle can modify parameter values, after a short press ON/OFF setting value decreases, and short press

MODE key set value increase, modify, long press ON/OFF button or long press MODE set numerical stop

flashing and save; Short press ON/OFF switch can continue to modify again other parameters; Again, long

press ON/OFFR + MODE key to exit the Settings interface;               

Method Two: in the condition of a certain parameter, short press MODE key set numerical flicker and

increases, short press the ON/OFF set values increase or decrease in small, again long press ON/OFF

MODE key parameters of save the changes and exit interface;

4.4Rocker arm adjusting the motor speed,from up and down, the motor speed increase; hands off,let it go back to zero.
