To turn on the KT-LCD display, first turn on your battery then press the middle function button for 3 seconds. This brings up the first of 3 information displays about showing information about your ebike, such as battery levels, trip distance, temperature, cruise function, lights, brakes, motor temperature, error codes and more. To scroll through the 3 displays, press the middle function button briefly and it will change from display to display.
To control the general project settings hold down the up and down arrow keys for 3 seconds. This will bring you to your first settings. Here you can control maximum speed, wheel size, (very important), mph vs km, and temperature settings. To change the settings use the up and down arrow keys, when your selection appear press the middle function button It will save your settings and allow you to scroll to the next settings. When you are done making your selections hold down the up and down arrow keys for 3 seconds. This will bring you to the Parameter settings menu, where you will see a blinking P1 at the bottom of your screen.
P1 controls your motor characteristic parameters. You will want to check with your manufacturer for the correct settings for your motor.
Press the middle button to scroll to P2.
P2 controls wheel speed pulse signal. Again if you don’t know consult your manufacturer.
P3 Sets your pedal assist function. The settings are 0 through 5. When set to 0 the
throttle is dependent on the PAS Gear Ratio. When set to 5 the throttle
will provide the most power.
P4 Sets the Throttle Start-Up Setting. This is an important one. When set to 1 the throttle will only activate the motor after the motor has been activated via pedaling.
When set to 0 the throttle activate the motor when triggered
P 5 is your Power Monitoring Setting. Again this is important. If the setting isn’t correct you won’t be able to determine how much you have left in your battery. There are settings for 24v, 36v and 48v. If you don’t know the correct settings, set this to 0 for real-time voltage mode.
When done with these 5 settings press the up and down arrow keys to move to the C Parameter settings.
C1 is your Throttle Start-Up Setting. Check your manual for your preferred settings
C2 is your Motor Phase Classification Coding Mode. These parameters set the different phases of the motor when using a sine wave drive.
