TBLE-02S problem
 

I have a Tamiya M05 which I recently upgraded some parts on.
After I finished putting the parts on (TRF Dampers, front uprights, steering turnbuckle) the steering wouldn't return to centre then while troubleshooting that problem, the ESC stopped working and just beeps with a red light flashing.

I tried cycling through the settings but its still doing it. I charged the battery (2s LiPo) and transmitter, and tried a second receiver, but its still doing the beep flash thing.

Both receivers work in a second car so I don't think the controller/receiver are the problem.

Can someone tell me how I troubleshoot an ESC to determine if its at fault? I don't have a spare.

Thanks,

Is your receiver and transmitter binded? It almost sound like it lost the bind.

I can understand the frustration on the TBLE02S. I run them on most of my newer Tamiya chassis but it was frustrating setting it up in the beginning.

The owner's manual is poorly written too. They should have block diagrams instead of all the words you have to read.

Once you confirmed that the receiver and transmitter has properly binded, redo the setup on the TBLE02S from the beginning by pressing the set button and turning on your power.

Thanks, I will try to re-bind it tonight, thanks for that :)

Out of frustration and with a race meet looming, I bought a second mini, fully hopped up with the racing Hobbywing 13T/35A combo.

On that one, the motor goes, but the servo doesn't even respond. Then I tried my old servo and now that one doesn't work either, even when testing it on my XRay T4, which is a known good car :(

Frustrating hobby this...

Did you try without your servo connected (the original one)? I had a similar problem where the servo fried and when it was connected to the receiver, it would cause the ESC not to arm. Unplug the servo and it was fine.

Were all the electronics working before you started started your upgrades? And they were not part of the upgrade process?

Yes, I tried with and without the servo connected (on the first car with the original problem), and yes, it was working before we upgraded the parts (Dampers, Steering turnbuckle, front uprights) and initially seemed OK afterwards as it was running/steering on the stand.

I also tried it with a second known good receiver and have the same problem. The ESC is beeping at me the same it does when the ESC/Servo is wired incorrectly, but everything appears wired OK.

Call Tamiya customer service. 1.800.TAMIYA-A

I opened the TBLE-02S up and had a look - one of the chips was burned out so that explains why it wasn't working properly. Time to source a replacement.

Wow, sorry to hear. :(

here's one for pretty cheap. Nitro-Master is a reputable shop.

GL!

Thanks for the link.

I ended up grabbing a Hobbywing 13T combo and fitted that last week, along with the gear diff out of the "parts car" I bought, then took the car racing. That turned into a disaster but at least I am getting really good at rebuilding the thing :D

You're welcome! :)

:lol: Gettering good at rebuilding and having fun sounds like a win to me. :D

Sorry to post here but I have no idea where else to post this :(

Tamiya Build DT-03 is having major issues with the TBLE-02 S ESC!!

Alright so, here's the issue, can't believe not ONE stupid build hasn't gone painless.

The issue is that after tons of attempts to bind my Receiver with my Controller, the only way I could do that was attaching a battery pack on to it and then it would, going through the ESC didn't send power to the receiver at all.

So, what I'm looking at now is that unless I attach an external battery pack the car won't work at all, which makes it even more confusing here's why:

• With the battery pack both servo and speed controller works fine
• Without it, nothing works, yet I have it hooked up the right way.
• With JUST the battery pack it's only the servo I can control with the controller.
• Without the battery pack I cannot control anything.

This leads me to believe that the TBLE-02 S isn't sending power to the receiver at all. It is beeping green (short tones).

I have the Channel 1 for the servo and Channel 2 for the ESC and STILL nothing. I put the ESC into the Binding or battery slot and nothing happens. I then add the external Battery Pack and into the binder battery slot and it works.

I just don't get it, does anyone one know what to do with this TBLE-02 S??? It just isn't playing nice. Does it need to be set up?

When I turn it on it's just beeping right away, nothing happens. I have configured it to run with Brushed Motor as I'm just using the Torque Stock 540 engine it came with.

Please guys if you have any clue, please help cause this is wreaking my brain here.

Any help at all would be massively appreciated!

Thanks

It's the Neo Fighter Buggy I'm working on and the electronics just don't want to play nice. 

PS. CARSON Reflex Wheel Ultimate Touch 2.4Ghz is my controller. It did bind well with the extra battery so it's not that, it's the TBLE-02S that's not playing nice again

Yes Tamiya ESCs tend to have fairly weak BEC power, likely not enough for many modern servos. Which servo are you using? The product page includes this warning:
I think one way to test is to leave the servo unplugged and see if the ESC will work without the extra receiver battery. If it does looks like an external BEC with enough power is needed as already mentioned.

YIKES! WHAT!?!??!

It sounds plausible guys, I mean from what I am seeing it could very well be the issue. I'll have to try it out in a moment.

I am using a Futaba Servo S148 3,0kg !!! I think you guys are right! IT WON'T power this if it can only handle 1.5!! that's ridiculous if that's the limit. :( What should I do now? Get a new ESC or new Servo?

The details of my servo is as follows:

Notes from the Tech Department
The S148 Standard Servo yields increased power and speed with a reduced size
and weight compared to the S128, yet uses the same gears and servo cases.
This servo is a replacement for the following servos.(S6,S17,S18,S23,S26,S28
S38,S128)

This servo can produce high-current draw from your batteries.
If using NiMH or LiPo batteries, make sure they are capable
of delivering sufficient amps.

(I HAD LINKS HERE but am not allowed to post any yet... I'm a shiny newbie it seems)

Finally, how did you guys find out about the BEC? Where does it state it cannot draw enough power through that set up? Also what does the BEC stand for? :/

And very lastly I'm thinking about getting this ESC as a replacement, should I go with this?

ESC TEU-105BK ?
(I HAD LINKS HERE but am not allowed to post any yet... I'm a shiny newbie it seems)

Or the TEU-101BK as it has a BEC line for the battery?
(I HAD LINKS HERE but am not allowed to post any yet... I'm a shiny newbie it seems)

Guys thank you so much for chiming in with this and coming to my rescue!

I am seriously seeing this to be the main issue! I bet you guys are right, I just don't get why a new ESC TBLE-02S cannot send more power through when others can. On my HotShot I have the same Servo and different ESC and it works fine. :(

Wow that's surprising, I wouldn't expect a problem with a S148. Especially just getting it going, 8mA (0.008A) at idle is far lower than 1.5A. Might be some other issue? :confused: I still recommend unplugging the servo as a test.

The note about the BEC is on the product page here:

ESC TBLE-02s

BEC stands for Battery Eliminator Circuit. As in eliminate the traditional receiver battery of 4.8 to 6V. The circuit, basically a voltage regulator, drops the higher voltage of a typical surface RC main battery pack down to the traditional level safe for all servos and receivers.

I just tried unplugging the servo and see if that made a difference... it didn't. The engine is still beeping and the green light is still flashing :(

I tried my wife's 104BK with the new car and servo and it all works perfectly. Could it really be a ESC flaw after all?

Or is there a reset function or a setup I'm missing here?

What does Low Voltage Protection Setup mean?

Maybe mine is off? or am I not understanding the meaning of Low Voltage Protection? Sorry I feel pretty dumb now :(

Low Voltage Protection is for lipo battery packs. Lipos are damaged if discharged too far, so protection features have been added for them. If you are using nimh packs definitely turn that setting off.

Do you think by turning that off, it could pass through enough juice to power the receiver? Or is that just another feature that actually doesn't solve my problem?

It won't provide more power, but it will eliminate the possibility of that setting causing a shutdown. Again, only if using nimh (or nicad) battery pack, if using a lipo have it turned on to protect the lipo from over discharge damage. The receiver by itself, servo disconnected, should use a very small amount of power.

Sorry guys at the time i posted that i was pretty upset bc some of the attitudes you get from people on here...at least to me...that particular speed controller..i do not own but i did ask a loooot of questions about it...thats the brushless one right?....with tamiya you do need to know that there is no warranty on them at least thats what i was told ...you can buy them in the states supposedly hard to find..and they dont have the correct power for servos...i think my thread on that particular problem is on rccrawler....under cc01 same user i.d. i dont change my name...

Also that particular esc comes with the cc01 and other kits now...the rep told me they only sell their electronics in japan...or wherever there based

The one that i do have is brushed...and all it needed was breaking the motor in correctly and a bec...i use the one from castle...best quality brushed system I've come across...


again sorry guys

Firebender- Sounds like you got a defective TBLE02-S. :(

Appears your BEC is not working properly in your case. I run several TBLE02-S in my cars and when the receiver is not binded to my transmitter (transmitter turned off), ESC beeps.

In your case your receiver is not turning on due to no power via BEC, causing the beeps?

BTW, the low voltage cutoff is imho too low to run Lipo's on the TBLE02-S.

I use a separate LVC (alarm). For my driving, I found that my car can run two 10min spirited runs (4200mAh) ending at 3.83-3.85v per cell which is a good voltage for storage; so I set the count down timer on my radio to beep giving me a heads up at 10min.

I set the LVC alarm at 3.7v just in case I forget to start the count down timer. When the battery drops below 3.7v, the audible alarm sounds as backup.

Here's what it looks like, LVC showing 3.84V. I bought this at Amazon for like $5? I use velcro on the back of the unit and strap it onto the battery wires or wherever convenient on the chassis.

You are right I think my ESC is defective and has been from the beginning. It was a mistake in the Grasshopper box, maybe someone swapped it before shipping with a defective one and that's why I was having such a headache with it.

I've cannibalised my Grasshopper that I've since upgraded with a TEU-105BK ESC and put it in my Neo Fighter Buggy, now it's all working as it should. I'll get a cheap 101BK off of eBay for the Grasshopper which I'm not using much as it was just bought for nostalgic reasons. ;)

Thanks for replying, I really appreciate it :) Have a wonderful summer :)

No problem and great to hear you got your Neo Fighter working! :D
Have fun with your new car.

I did a bit of a different design of it, it's complete now. I'd show you but I cannot post links here yet, so I don't know how to upload an image :/

But thank you once more for the help :)

I know the thread is old, but I had a similar experience with the TBLE-02s and I'd like to say how I coped with it.
The ESC was on my MF-01X, which - though 15 months old - hasn't much use.
Suddenly, while playing (a newly installed motor fan may have something to do with it) it started behaving like Depth Charge's: Nothing was working, the TBLE-02s was blinking and - when the motor was connected - beeping also.
This regularly means the ESC gets no signal: The receiver had no light, and after checking I found that the ESC was sending only 1V to the Rx. Also, a component on the ESC was blackened like burnt.
I decided that the BEC parts of the TBLE were gone, but I was reluctant to declare the whole ESC dead yet - the brushless sensored capability is something I want to check in the future.
So, I decided on fixing this somehow.
I got a $3 Hobbywing 3A UBEC which seemed the obvious choice.
Upon installing, I found that it didn't work well with the Tactic TTX300's receiver (TR325).
So, I tried with another TX&Rx (the Quanum pistol from HK).
Also, against common sence (and the UBEC manual and forum advices), the TBLE does not cooperate when the middle (red) cable is disconnected - but if it is connected, along with the UBEC, everything goes fine!

TL;DR : don't throw it away, experiment with a cheap BEC first.

Just noticed this old thread myself, and yes BEC error, we have just started to run the TT-01E trucks and was originally to be box stock electrics (Which means TBLE02 ESC) but out of 10-12 regulars we have had 4 esc failures, so now most have gone to the Hobbywing Quicrun brushed for reliability.
