Instrument Instructions (YL80C Display)

Product Name and Model

Intelligent LCD display for e-bike; model: YL80C.

Specifications

• 36V/48V power supply
• Rated working current: 15mA
• Maximum working current: 30mA
• Leakage current at power-off: <1uA
• Working current at the supply controller end: 50mA
• Working temperature: -20~60℃
• Storage temperature: -30~70℃

Appearance and Dimensions

The display unit shows speed, trip distance, battery level, and assist level. It features buttons for power, mode switching, and adjustments.

Function Overview

The YL80C display offers various functions including: Battery level indicator, Motor power indicator, Assist level adjustment and indication, Speed indicator (real-time, maximum, average), Distance indicator (trip, ODO), Push assistance control, Headlight control, Error code indicator, and Custom parameter settings.

Functional Area Layout

The display interface includes indicators for: Battery level, Headlight, Bluetooth connection (reserved), USB connection (reserved), Fault, Speed, Assist level, Push assistance, Numeric values, Speed unit (km/h or mile/h), Trip distance, ODO, Maximum speed, Average speed, and Riding power.

Button Definitions

The display unit has five buttons: power button, plus button, minus button, headlight button, and switching button.

General Operation

Power On/Off

Press and hold the power button to turn the display and controller power on. Pressing the power button again turns the e-bike off. The display automatically powers off after 10 minutes of inactivity to save battery.

Display Interface

Upon powering on, the display defaults to showing real-time speed and trip distance. Pressing the switch button cycles through trip distance, ODO, maximum speed, average speed, and riding power.

Push Assistance

Press and hold the assist button to enable electric push assistance mode, which runs the e-bike at a constant speed of 6km/h. Releasing the button stops power output. This mode is intended for pushing the e-bike, not for riding.

Headlight On/Off

Pressing the headlight button turns on the headlights and dims the display backlight. Pressing it again turns them off and restores the display's normal brightness.

Assist Level Selection

Pressing the '+' button cycles through the assist levels, thereby changing the motor's output power.

Battery Level Indicator

The battery level is indicated by five segments. All segments are lit when the battery is fully charged. As the battery depletes, segments turn off. In case of undervoltage, the indicator outline will flash, signaling the need for charging.

Motor Power Indicator

This indicator displays the output power of the motor.

Error Code Indicator

When a fault occurs in the electronic control system, the display will automatically show an error code. Refer to Schedule 1 for detailed definitions of error codes. Troubleshooting is necessary for the e-bike to function normally.

General Setting

All parameters can only be set when the e-bike is stopped (speed is 0).

Entering Setting Interface

Press and hold the '+' and '-' buttons simultaneously for more than 2 seconds to enter the selection interface of general setting options.

Navigating Settings

Use the '+' button to switch between general setting options and the '-' button to enter the parameter modification or selection interface.

Saving Settings

Use the '-' button to save the parameter and return to the selection interface. Press and hold the '-' button to save the parameter and exit the selection interface.

Trip Distance Reset (tC)

Set tC-n to not reset the trip distance, and tC-y to reset the trip distance.

Backlight Luminance Setting (bL)

Options bL-1 (minimum luminance), bL-2 (standard luminance), and bL-3 (maximum luminance) are available for backlight brightness adjustment.

Metric/Imperial System Setting (U)

U-1 represents the imperial system, and U-2 represents the metric system.

General Parameter Setting

The following steps are for setting general parameters when the speed is 0:

Wheel Diameter Setting (Ld)

Set Ld to match the e-bike's wheel diameter (available parameters include: 8-26, 700C, 28-30 inches) to ensure accurate speed and distance readings.

Speed Limit Setting (LS)

Set LS to define the maximum riding speed. The selectable range for the maximum speed setting is 12km/h to 40km/h.

Custom Setting

Custom setting options are available to meet individual requirements, including: battery level setting of the display, assistance parameter setting, current limit setting, assistance sensor setting, speed sensor setting, handlebar function setting, system setting, and power-on password setting. Not all protocols support all custom setting options; some only support a subset.

Assistance Sensor Sensitivity Setting (SCN)

SCN refers to the assistance sensor sensitivity setting option. The setting range is 2-9, where 2 means maximum sensitivity and 9 means minimum sensitivity.

Power-on Password Setting (PSd)

PSd-Y means a power-on password is required, and PSd-N means no power-on password is required. If PSd-Y is selected, a password modification option becomes available.

Restore Default Settings

dEF refers to the setting option for restoring default parameters. dEF-Y means default settings need to be restored, and dEF-N means no restoration is needed. In the normal display interface, press and hold the '+' and '-' buttons simultaneously for more than 2 seconds to enter the restore default settings interface. Switch the parameter by pressing the '+' button. If 'Y' is chosen, press the '-' button to confirm. The display will indicate dEF-0 and automatically start restoring settings. Upon completion, it exits and returns to the normal display interface.

Battery: Further Information and Maintenance

The full charge battery range depends on loading weight, road condition, and battery capacity. For longer storage, especially during winter, keep the battery fully charged in a dry place. Recharge the battery every 2-3 months if it is not in use.

WARNINGS

• Keep the battery out of reach of children.
• Never attempt to open the battery.
• Only use ENGWE-supplied batteries. Do not use batteries from other models.
• If the battery is damaged (e.g., dropped or due to an accident), there is a risk of electrolyte leakage. Beware of chemical burns and stop using the damaged battery immediately.
• Do not touch the battery without gloves and ensure no acid contacts your eyes.
• Do not store the battery in temperatures above 95°F (35°C) or below 23°F (-5°C).
• Do not allow the battery to run down completely before charging. Charge the battery before storing the product. A completely empty battery may become unchargeable.
• Charge a new battery for at least 4-6 hours before first use. Avoid prolonged charging. Overheating or undercharging can shorten battery life and reduce product run time.

IMPORTANT: BATTERY DISPOSAL

• Battery must be recycled or disposed of in an environmentally sound manner.
• Do not dispose of the battery in fire, as it may explode or leak.
• Do not dispose of batteries in regular household trash.
