3 Function Overview and Key Definitions
3.1 Function Overview
• Use of a two-way serial communication protocol,
simple operation of the display via the external
5-key keypad.
• Speed display: displaying the real-time speed as
SPEED, the maximum speed as MAXS, the
average speed as AVG, remaining range TO
GO, Power W, Calory C .
• km or mile: The user can choose between km
and mile.
• Intelligent battery level indication: With an
optimization algorithm, a stable display of the
battery level is ensured, and the problem of fluc-
tuant battery level indication common with other
displays is avoided.
• Automatic light-sensitive lights:The headlight,
taillight and display light will be automatically
turned on/ off depending on lighting conditions.
• 5 levels off display backlighting: Different levels
• 5-Level-Support: setting power Levels 1 to 5
• Trip distance indication:The maximum distance
displayed is 99999. Single-trip distances TRIP or
the total distance TOTAL can be displayed.
• Display of error messages
• Walk assistance
• Settings: Various parameters, e.g. mode, wheel
diameter, speed limit etc., can be set on the com
-
puter via a communication cable. See the setting
• Maintenance warning (this function can be deac -
tived): Maintenance warning information is dis-
played based on battery charge cycles and riding
distance. The display automatically estimates the
battery life and gives warnings when the number
of charge cycles exceeds the set value. A warning
will also be displayed when the accumulated total
riding distance exceeds the set value.

6 Error Code Definitions
The DP C10.UART can show e-bike faults. When a fault is detected, the icon will
be displayed. In the speed field one of the following error codes will be displayed:
Error Code Error Description Error-shooting Method
“03” Brake enabled Check whether a brake cable is stuck
“04” The throttle has not returned home Check if throttle has returned home
“05” Throttle fault Check the throttle
“06” Low voltage protection Check the battery voltage
“07” Overvoltage protection Check the battery voltage
“08” Motor hall signal cable fault Check the motor module
“09” Motor phase cable fault Check the motor module
“11” Controller temperature sensor failure Check the controller
“12” Current sensor failure Check the controller
“13” Battery temperature fault Check the battery
“21” Speed sensor fault Check installation position of speed sensor
“22” BMS communication fault Replace the battery
“30” Communication fault Check the controller connection
Error display
The motor temperature has
reached the threshold.
Note: Error Code 10 will probably appear on the dispaly when the
e-bike is climbling for a long time. This indicates that the motor
temperature has reached the protection value, in which case the
user needs to stop the e-bike for a rest. If the user continues to run
the e-bike, the motor will automatically cut off the power.
“10” Stop the bicycle until the error code "10"
disappears from the screen.
