S866 LCD Settings & E-Codes.

[@leehyatt76]

Is there a way to program the speed limits for each assist level? My ebike came with this display and it has 3 levels of assist which are programmed to be at 5 mph, 10 mph, and 15 mph. I would like to adjust this to be closer to 10, 15, and 20. Do you adjust the max speed and number of assists and does it just evenly divide the max speed by the number of assist levels you set it to? Also, my display is frozen and will not allow me to adjust certain settings. It is not password protected. It's odd!

[@theebikeguy3852]

Change PO5 from 3 to 5 this will alow more speed options, there is no setting each level, but by going to 5 levels that may get you where you want to be also make sure p08 is at 100.

I got E10 straight away 😅 ,still works but i thought it was compatible with KT esc's/controllers ,i should have bought the kt7 the kit came with but i went cheapskate 😅 🇬🇧

[@КириллИбрагимович-т4ь]

So looks like this display is not compatible with my controller (48V22A Lishui Sine-wave) there were kd21display on the bike. Or is there a way to fix that?

[@theebikeguy3852]

@user-iy7tj7hj2t The controller and LCD are programed together, in most cases you need to buy the same display you had, Even if you're able to make another display work with it, it's likely you will have issues..

Where did you get the list of error codes???

Hi, is there a way to adjust it to prevent it from jerking a lot? I’m using an E-Bike

Set P-12 to 1 it will take off smoother.

Hi there I bot A new controller bike and how can I set the controller it's A U 1

[@theebikeguy3852]

@@OscarReyes-l4f If you bought the controller specifically for that unit, it will already be pre. Programmed. If you just bought a random controller, you will also have to replace the LCD display because they will be married together, and information will be shared between the controller and lcd display. That exact thing being in front of me. I'm sorry but I can't tell you.

[@amirouw]

i got a problem with it ... if i let go the throttle at high speeds then after a couple of seconds again try to push the throttle itll jerks like youre pulling on the brakes????

[@theebikeguy3852]

Could be the throttle, or possibly a break inhibioter acting up, If you disconnect both breaking heaviers depending on the style of E bike or E scooter, maybe only one see if you still have the same. Issue if you do, it's possibly a partly defective throttle. Like a it's like a piece of plastic that has broken inside and the Spring is getting stuck in a specific position. Not allowing it to function properly or the hall center is acting weird. Usually a error code will be associated with it but not always

[@amirouw]

@@theebikeguy3852 yeah its an E7 ..now why is that

[@theebikeguy3852]

@amirhoseinkargar3733 that would be the motor or possibly controller,,,,, if you put the back wheel off the ground and spin the tire slow with hand on it forward then backwards, if I feels kind of jerky, open up the unit, see if the 3 phase wires are melted together. If not disconnect the Hall sensor check your prongs for bent conecters or Corrosion?, If everything looks good, plug it back up. If you have the high go connector style line the 2 arrows up on either side. If it is just a quick disconnect, it's obvious how it snaps back together. Get back with me after you do this. If you find nothing, do not put it back together, I'll tell you how to run a test on the motor.

[@amirouw]

@@theebikeguy3852 i checked the resistance between phases before ...thyre all the same. the motor is 100 percent ok im sure of it ... it works .. i turn on the setup and start riding the vehicle daily...but every day i have this issue and after it e7 shows up

[@theebikeguy3852]

@amirhoseinkargar3733 OK, so you also tested the 3 phase wires while spinning the motor I guess? I would suspect that you would have a faulty controller. As the capacitors warm up inside, it probably starts acting up. Or one of the mosfits cold be going south..... But again, sometimes it's harder to diagnose unless it's directly in front of you. Hope some of the information I've given you helps. If not, good luck with the project, I'm sorry you're having issues with it.

[@amirouw]

hi why i get E10?

[@theebikeguy3852]

Communication error between LCD and Controller, you can check P20 to 0 and if it will work, First try to unplug lcd from.controller make.sure there are no bent pins then reconnect

@@theebikeguy3852 i did ...but i noticed something ...theres a rear led that comes from controller ....at start up they glow but i accidentally shorted them and now they stoped glowing ... is it the whole controller board or what?

@amirhoseinkargar3733 what kind of bike you got that has lights on the controller

[@amirouw]

@@theebikeguy3852 led on the back of the bike are connected to controller board

[@theebikeguy3852]

@@amirouw OK, well, I think you're referring to the rear tail light. It is possible for certain things to be working and others not to be and the controller to be partly burnt up. It's hard to say in your case without actually running test on it and without it being in front of me. Well well obviously I can't run test. Or it could have been that you burnt out the lights. It's hard to say. If you have a electric bicycle shop nearby, I suggest that you take it there. Sorry, you're having a difficult time with it.
