3.3 Speed display area
Unit：MPH, KM/H
The speed signal is taken from the Hall signal inside the motor.Sent to controller
by controller(Time of single Hall period,unit:1MS).The display calculate the true
speed based on wheel diameter and signal data calculate the true speed.
(The motor Holzer also needs to setthe number of magnetic steel)
3.4 Vehicle power gear adjustment , 0-9 0-9 digital display.

4. Setting
P01: Backlight brightness:The 1 level is the darkest, Level 3 brightest; Default:3
P02: Mileage: unit, 0: KM; 1: MILE; Default: KM
P03: Voltage level: 24V, 36V, 48V, 52V, 60V. Default:52V
P04: Dormancy time: 0 means no dormancy; Other numbers are dormant time.The
range is 1-60 minute. Default: 5
P05: Reserve
P06: Wheel diameter: The unit is inch. The accuracy is 0.1; Default:10.0
P07: Speed measuring magnetic steel number.The range is 0-255. Default:28
P08: Rate-limiting: The range is 0-100km/h.Default: 100
P09: Zero start, no zero start setting; 0 means zero start.1means no Zero
P10: Reserve
start.Default: 0
P11: EABS switch choose.The range is 1-5.0 means closing.1 means weakest. 2
Means strongest
P12: Soft and hard start strength.The range is 1-5. The softest is 1.The hardest
is5.Default: 3
P13: Reserve
P14: Reserve
P15: Controller under-voltage
P16: ODO Zero setting: keep pressing + for 5 seconds,ODO will zero clearing.
P17: When it shows 0,it can not use cruise.When it shows 1,it can use
cruise.Default:0
P18: Reserve
P19: Reserve
P20: Communication protocol is defaults 4. It can not change.
4.Introduction of buttons and interfaces
1. When it is shutdown, long-time pressing to turn on the power.
When it is power on, it can change interface between the ODO, TRIP,
VOL,by pressing for short time.
2. When it is power on, long-time pressing to turn
off, short-time pressing can change gear.
3. Long-time pressing and can get into the menu to
change the interface.
4. Get into the setting interface, short-time pressing
can change parameter.
Short-time pressing or long-time pressing can add or reduce the
numerical value.After changing,short-time pressing to change the
nextnumerical value.After changing,long-time pressing and
to get out of the interface,or waiting 8 seconds, it can save the numerical
value and drop out by itself.
5. Crankshaft regulating motor speed by Up and down.
Motor speed increase;Relax hand itreturn to zero.
