  1. My LCD3 display blanks out on occasion, the bike shuts down and I get a code 3 error come up on the screen. I have to turn everything off and then on for it to work again. Any help out there?
  2. Hi all, I thought I would share some of my findings regarding Luna's KT-LCD3 and P5 - Power Monitoring Mode. I have the basic Thin with an upgraded screen and controller from Luna Cycle. Once hooked up, I notice that the battery level on the screen did not match the battery level that's on the battery. Once down to 0 level on the screen, I can see there's still some power left on the battery. So here's what I found. If you get to the P5 function on the screen, you'll find that you can change the setting from 0 to 12. For the Thin, I've seen 5 as a default. So off for a ride I go, having a great time, and later found myself down to nothing on the screen. I've figured that I've drained the battery down for the low voltage protector to kick in. Bike was a tank to pedal and had about 2.5 miles to get home... along with a few hills. I then remember someone saying that if you set the setting to 0, then you can get a real time of the batteries voltage. Sure enough, the meter showed 1 bar and was able to get the controller above the low voltage protector for the bike to move. I also noticed that if I set the PAS to 2, the low voltage would kick in as well as using any throttle. So as long as I left the PAS to 1, and provided and extra effort in peddling, I was able to get home. I also want to note that if you set P5 at 5, the battery level drops at a faster rate from 2 to 1 as compared to 4 to 3. YMMV
  3. Here you can find the right settings for your Sondors eBike generic LCD! KT LCD3 settings for Sondors buy a LCD here: klick Max. Speed: leave it, or set it to 25 km/h Wheel Diameter: 29 for 4.9" tires, 28 for 4.0" Metric and Imperial Units: your choice P1 = 100 (Motor Characteristic Parameter Setting Mode, 1 - 255) P2 = 6 (Wheel Speed Pulse Signal Setting Mode, 0 - 6) P3 = 1 (Power Assist Control Mode, 0 or 1) P4 = 0 (Handlebar Startup Mode, 0 or 1) P5 = 12 (Power Monitoring Mode, 0 - 40) C1 = 01 (Power Assist Sensor and Parameter Select Mode, 00 - 07) C2 = 0 (Motor Phase Classification Coding Mode, 0 - 7, 0:sin wave) C3 = 8 (Power Assist Ratio Gear Initialization Mode, 0 - 8 ) (C3=6 WARNING! Bike starts running forward on it’s own at power up!) C4 = 0 (Handlebar Function Setting Mode, 0 - 4) C5 = 10 (Controller Maximum Current Adjustment Mode, 00 - 10) C6 = 3 (Backlight Brightness Adjustment Mode, 1 - 5) C7 = 1 (Cruise Function Setting Mode, 0 or 1) C8 = 1 (Motor Operating Temperature Display Mode, 0 or 1) C9 = 0 (Startup Password Setting Mode, 0 or 1) C10 = n (Automatically Restore Default Setting Mode, n or y) C11 = 0 (Attribute Selection Mode, 0 - 2) C12 = 4 (Controller Minimum Voltage Adjustment Mode, 0 - 7) C13 = 0 (Brake energy recovery - recuperation - only works with the corresponding controller, 0 - 5) C14 = 2 (Coordination of support levels, 1 - 3, 2 = standard) (description of the C parameters follows) Step by step / Details What you should now to set up your KT LCD3 display: General Settings: Under power off status, hold the „power“ button long, the meter is turned on. Within 5 seconds after boot-up, hold „up“ and „down“ simultaneously for about 2 seconds. Now you are in the settings menu. (between each setting parameter press „power“ to save and to get to the next parameter) Max. Speed: leave it For Europe: set it to 25 km/h to be on the legal side. Wheel Diameter: set it to what it is: 29 inches Metric and Imperial Units: your choice After finishing metric/imperial unit settings, the speed and mileage units stop flashing. Within one minute after stoppong flashing, hold „up“ and „down“ simultaneously for about 2 seconds to enter the P parameter settings environment. Need values for our motor are (http://www.szbaf.com/en/components/component/motor/rm-g06350d.html): Cadence (Pulses/Cycle) 6/1 Reduction Ratio 1:5 Magnet Poles 20 P1 Motor Characteristic Parameter Setting Mode P1 is motor characteristic parameter setting mode. P1 = motor gear reduction ratio x number of rotor magnet pieces, just rounding if there’s any decimal. Sondors: Ratio 5 x 20 Magnet Poles = 100 = P1 P2 Wheel Speed Pulse Signal Setting Mode P2 is wheel speed pulse signal setting mode. If wheel generated 1 pulse signal by a revolution, P2 should be set as1. If wheel generated 6 pulse signals by a revolution, P2 should be set as 6. If users didn’t configure the pulse signal system, and then P2 parameter setting can be 0. The setting range of P2 should be between 0-6. 0 : motor hall sensor only (speed is only shown while motor is working) 1-6: Pulses per Cycle Sondors: Cadence (Pulses/Cycle) 6/1 = 6 = P2 P3 Power Assist Control Mode P3 is for power assist control mode, when P3 parameter setting is1, power assist control mode is gear 5 of “imitation torque control” mode, when P3 parameter setting is 0, power assist control mode is gear 5 of “speed control” mode. P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1 Sondors: P3 = 1 P4 Handlebar Startup Mode P4 is handlebar startup mode. When P4 setting is 1, indicating the handlebar is under “non-zero startup” mode, namely, the handlebar can be effective only after startup the foot power assist. When P4 setting is 0, indicating the handlebar is under “zero startup” mode, the motor can be startup by the handlebar directly. P4 setting range is 0 or 1 Sondors: P4 = 0 P5 Power Monitoring Mode P5 is power monitoring mode, when P5 setting is 0, the power monitoring is the “real-time voltage” mode. Namely, it is the method to determine the battery capacity based on real-time battery voltage. When P5 equals to a specified parameter, the power monitoring is the “smart power” mode (this parameter is determined by the battery characteristics, ordinary 24V lithium is generally is 4-11, 36V lithium is between 5_15). P5 setting ranges from 0-40. E.g.: 9 = 24 V 12 = 36 V 15 = 48 V Sondors: 36 V -> P5 = 12 To exit the programming mode just hold „power“ some seconds. After finishing P parameter settings, the P5 parameter stops flashing. Within 1 minute after stopping flashing, hold “up” and “down” for about 2 seconds to enter the C parameter setting environment. C1 Power Assist Sensor and Parameter Select Mode C1 is power assist sensor and parameter select mode. C1 Quantum power assist sensors or similar products 00 5 magnet sensor 01 8 magnet sensor 02 10 magnet sensor 03 12 magnet sensor 04 Power assist sensors from other manufacturers 05 06 07 Sondors: C1 = 02 C2 Motor Phase Classification Coding Mode C2 is motor phase classification coding mode. It is served as identification parameter of different phases of the motor when using sine wave drive and the default value is 0. When C2 setting is 0, indicating that the used Quantum motor phase is an ordinary one. When the setting is a certain value, indicating a particular motor phase is used. C2 setting range is 0-7. Sondors: C2 = 0 C3 Power Assist Ratio Gear Initialization Mode C3 is initialization mode of power assist ratio gear. The setting range is 0-8 (gear). When C3 setting is 0, the meter is switched on, and the power assist ratio is at gear 0. When the setting is 1, the meter is powered on and the power assist ratio is at gear 1, and so on. Sondors: C3 = 8 C4 Handlebar Function Setting Mode C5 Controller Maximum Current Adjustment Mode C6 Backlight Brightness Adjustment Mode C7 Cruise Function Setting Mode Activate the Cruise Mode: C8 Motor Operating Temperature Display Mode C9 Startup Password Setting Mode C10 Automatically Restore Default Setting Mode C11 Attribute Selection Mode C12 Controller Minimum Voltage Adjustment Mode C13 Brake energy recovery - recuperation - only works with the corresponding controller C14 Coordination of support levels (C Parameters are following some time) Want a complete manual?

  4. Speed and power limit with new motor Hi dear Sondors community, I am experiencing a very strange problem concerning the speed limit on my Sondors Custom 350 watt 36 volt fatbike. Since neither me nor the Luna Cycle support was able to figure out what the reason for this problem could be, I hope that maybe somebody in this forum can help me with this issue! The situation is the following: I have two Sondors Custom 350 watt fatbikes, both are equipped with the Luna Cycle KT LCD3 Display and the Hot Rod 20 amp controller, both worked fine and top speed was approximantely 25 mph. one of them at one point had a motor damage, therefore I ordered a new motor from Ebay and installed it succesfully. It should be the same Bafang 350 watt motor, just the axle is slightly broader, the wattage and volts are the same after installing the new motor (and despite checking the recommended KT-LCD3 settings like 20 times) this fatbike with the new motor had a speed limit of approximately 18 mph which seems to be impossible to remove since I switched both, the controller and the KT-LCD3 Display, from one bike to the other to check which component could be causing this problem, I am pretty sure that these components are working fine. But the bike with the new motor is limited in speed and max wattage no matter what I do. I was told, that the Display is responsible for the speed limit, but since I've tried to switch Displays, it seems impossible to me that this could be the cause for this problem. Anybody has an idea how I could remove this speed limit? Thank you very much folks! For those interested, I attach the conversation I had with Luna Cycle trying to figure out what the poblem is, they suggested to ask the Sondors forum for help since neither they knew what issue could be the reason for this strange limit. YouTube-Video "KT-LCD3 Display is a MUST HAVE accessory for the Sondors Ebike." Dear Seb, Yes, it is exactly how you just described and we changed the motor with the same bafang 350w engine with identical serial nr. Could it be that this motor needs other settings in the LCD? Thanks for helping in solving this mystery!

And if I understand correctly you also swapped the controller from the older bike to the problem bike and still is slow???? If you did swap both LCD and controller to that bike and still limited to 20mph… there can only be an issue in the motor I think. Did you change the motor?

As I already changed the new hotrod controller with the old one, I don’t think there is any difference in changing it with the one in the other ebike. It is for me not logical why the bike is still limited. Thanks, Hannes [[941f9d177d1777ec77459b98d38b75d793827e42-1026120604]] Type your response ABOVE THIS LINE to reply hannes mitterer Subject: Sondor HOTROD controller and Luna KT-LCD3 SEP 01, 2017 | 05:21PM UTC Seb replied: We honestly do not know… it’s possible that some settings have to be changed to work with the new motor…Possible that the motor is not exactly like the previous motor (inside motor windings). But if the issue after changing the controller and LCD is still present, it can only point toward the motor.. (or a weak battery if you think.. but does not look like it from what you are telling me!) But what I would recommend is to check the Sondors forum and ask for help, post the model of the motor (and link) you have and ask if anyone had issues changing the motor. There is possibly a setting in the LCD that can make it better. https://sondorsforum.com/forum/1-sondors-forum/ Unfortunately there so many possible settings on the KT-LCD3, we only program them for the stock motor, and do not know the settings for other motors.

  5. LCD Display not displaying speed, battery, etc Hi everyone, I recently received my Sondors and I can't figure out why the LCD Display is not showing speed nor battery life ? I can change the pedal assist level, the maximum speed, size of wheels etc but it doesn't show my current speed reading and the battery is completely blank, what could cause that ? I bought the display on Ebay, it's this model : http://www.ebay.ie/itm/141957087134?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT And the Sondors on their website (not on Kickstarter/Indiegogo). Thanks ! Yann
  6. Hi! Due to the case that I still don’t have my bike, but wanna be prepared, I need some help/information Could anybody tell me what kind of connector is used at the bike for the Display? And how the pin configuration is? Just think about getting the KT-LCD3 here in Germany and solder the right connector. Thanks! Thorsten
