Product name:Electric Bike LCD Display Meter Product size about : 110*6.1cm/4.3*2.4in Product color: As shown in the figure Product material:ABS product features: 1. Nylon ABS material: High-quality plastic material is lightweight, Sturdy and has a long service life. 2. Comprehensive data: The LCD display can clearly display status and data, such as riding speed, time, temperature. 3. Backlight design: The backlight enables you to see the screen clearly in a dim environment. 4. Applicable controller: for JN Controller can automatically identify 24V, 36V, 48V, 52V, 60V, 72V voltage. This is a YF protocol, not suitable for KT. 4.1 x SW900 display with rubber strip adapter and fixing nuts and bolts This is the display that comes with our 2000w hub motor kit by default. 5 Notes: There are many tutorials on YouTube on how to configure the settings. illustrate: P01 - Display brightness: You can choose from 1 to 3, where 3 is the most bright option (for sunny days). P02 – Kilometres or miles per hour: depending on your location, you can select to display the speed in km (0 ) or mph (1). For this to work properly, you need to set the size of your ebike wheels. P03 – Voltage of battery and motor: this is where you will specify the volts of your battery and motor. You can select 24v, 36v and 48v. Normally, the SW900 is set to 48v so make sure you select the right voltage grade. However, the sw900 will work up to 72V. P04 – Display sleep timer: this come from zero to 60 mins. In this case, zero means your controller will stay on all the time and if 60 mins, it will shut down after 1 hr of no-operation (this will not happen if you are riding your electric bike though). P05 – Pedal Assist levels (PAS): there is a total of five (5) PAS. You will see a bunch of numbers with v next to it (meaning voltage), so dont freak out cos you dont need to do anything with that. In simple words, you can choose zero for 1 to 3 levels of PAS and one for 1 to 5 levels of PAS. I personally like the one setting, since it lets the system deliver more sensitivity in term of my pedaling efforts. P06 – Wheel size selection: this is where you establish the size of your wheels in inchs. This is important in order to display the right speed you are traveling. P07 – Speed measuring magnet: this element will be factory calibrated so better not to mess with it. Basically, based on the assistance mode you select and speed limit, it will tell the controller if the motor is delivering the right assistance and therefore if the battery is delivering the correct voltage. This is very important in order to indicate the controller to deactivate the motor if you reach your set speed limit. Ask your trusted bike shop what would be the right setting if you change the ebike motor. P08 – Speed limit: this is a very important setting since it will help you set the right speed that will comply with the local regulations and your comfortable riding speed. P09 – Zero and Non-Zero Start: This relates to thespeed control device device activation. A non-zero start means the speed control device will have a delay reaction of 1 sec. I believe this relates to safety rather than messing with your patience. P10 – Driving mode: you will see 0, 1 and 2, where 0 is to ride with PAS only, 1 for speed control device only and 2 for a combination of the PAS and speed control device. P11 – PAS sensitivity: ranging from 1 to 24, where 24 will give you more riding range due to less battery and motor usage. P12 – PAS start strength: you will find 0 for low strength and 5 for the fullest strength, meaning immediate start. P13 – PAS magnet type: you will have a 5, 8 and 12 type. This comes factory calibrated and will be directly related to the motor type you ebike has. P14 – Current limit of the Controller: set by the manufacturer, you will have a range between 1 to 20Ah. Dont change it if you dont need it. Precautions: 1. As we all know , the different computers display colors differently, the color of the actual item may vary slightly from the following images. 2.
