Yesterday it started dropping out at times... ...my wife had no issues. My initial guess is that your Zero Throttle Threshold is too small. A small motion of the throttle is kicking in the throttle the tiniest of bits which is enough to kill PAS. Perhaps your wife didn't have problems because she h...

...i would guess that this mode will only work with real torque sensor devices? but since there is no special hint in the docs that this is only usable with torque sensors i am curious if its compatible with stupid pas dics, too? i tried enabling torque mode, switching to torqpas and than i was los...

v3.12b1 Released Thanks to member k.ewin and others, an issue came to light in versions 3.1 and 3.11 that results in the CA hanging with " PC Connection... " on the screen and Setup Utility reporting a timeout. Version 3.12b1 should remedy this problem. There are no other changes so this is identic...

It was working before using the configuration that was included in the posting . The power LED's do not power up nor does the switch power the head lamp. The head lamp is power by the CA output power jack and the throttle button is the on and off switch for it. So the throttle assembly is not getti...

The throttle has no power level LED's and the switch for lights do not work as well. Hmmm - I took this to mean that this stuff never worked, but examining the picture and guessing at the throttle wiring and the harness wiring, it looks like it did. So - as AW said, this looks like a wiring issue -...

Ok. I just wanted to put closure on this posting of mine ... ...What I did differently was swap the TX and RX lines, and it worked! Thanks for getting back on this - glad you were able to resolve this as a hardware issue. That said, there does appear to be a comms issue when running 3.1 and 3.11 fi...

This is most likely a configuration issue caused by either: powering up the CA with a non-ZERO throttle as set by ThrI->ZeroThrsh (intended to prevent dangerous runaway on power-up but can occur with an improper setting) the throttle voltage exceeds the value of ThrI->FaultThrsh (intended to prevent...

I run 2WD with only a single motor temp sensor going to the CA. This avoids mechanical contacts (switches) in analog signals where tiny fractions of a volt are significant and relies on the supposition that with equal wheels and controllers, identical motors are doing about the same thing. Since the...

I'm also thinking about overheating due to some sort of electrical or mechanical malfunction in the wheel...something beyond putting the motors to a tough test. JLE offered some suggestions on this way back in early CA3 development: ... If you get two 20K thermistors and wire them up in parallel, t...

Well, the easy solution is get a CA3 and hook it up. This gets you automatic power rollback on overheating and all the other CA stuff. But, a DIY approach is to get a programmable (y = mx +b) meter and set up the m and b coefficients for the KTY-83. You will still need to address a weatherproof case...

Your solution is working, by changing the separator in intl.cpl it's solve the problem. If the CA setup utility does not work with a comma as decimal separator in Windows settings this is clearly a bug and should be fixed. Many European countries use a comma. I am happy that changing the separator ...

I do not understand why my test drive worked perfectly and the next day the settings were corrupted. I have not changed anything in between. That was a characteristic of the 3.1 firmware and shouldn't be showing up now... so not the best news. I'll take a look at your files straightaway. I'm thinki...

In attempting to install newer firmware the Setup Utility produces a popup stating that it is unable to find the CA3 within the time limit of 30 seconds. I just tried the XP laptop and it did not work either. Although there does appear to be some comms issue with 3.1/3.11, it seems you are experien...

It did not work with the Windows 10 laptop. I will try the slower Lenovo S10 Atom running XP later this afternoon.

Hmmm, somewhat surprising.

Can you please describe exactly how this failed?
(e.g. Never started, hung in the middle of download, verify failed, etc....)

Interesting. Thanks.

- Yesterday I did an upgrade to 3.11. I had 3.11b2 running before without problems. - After upgrading (and some "hardware work" such as shrink wrapping some connectors) I did a test ride and everything went smoothly - Today I connected the batteries and the CA booted to an error message: "SLOW PWR ...

Are you saying that i can just go ahead and cover all the internals with spray paint\epoxy? metals\wires\magnets? Please see: RUST: DIY Hub Motor Repair & Restoration by doc bass docBassMotorCoating.jpg Drill your cover like so - ideally with the hole aligned with the inner edge of the case. As Jus...

The CA3-DP has ver. 3.1B13 of the firmware, and it does not have Sempu listed as a PAS torque sensor. ... Also where can I find the Sempu pre-configured setting values? I'd like to enter them manually for now if possible. CA3.11_SempuDefaults.png After flashing the newest firmware it seems like the...

... and the issue where a small low torque pedal movement causes the motor to surge with a value way above what the multiplier should produce, usually following high power usage. Like I go fast up the hill, then gently change which pedal is down as I roll down the other side of the hill to my mailb...

(it might be helpful to update the Assist Scale Factor tooltip to reflect that Assist Start Level is subtracted, I would never have guessed that. ) Yep - I've argued about the sign as well, but from a certain Human Power perspective it makes sense. Unfortunately, my outlook just doesn't go that way...

The multiplier was at 10x ... my Hwt was 100ish and the motor wattage was 5-600ish. My start is at 65w now. Yep those were the 'ish' numbers I saw but now knowing the Start Assist for sure: we expect to see a motor power of motorPower = (100HW-65HW) * 10W/HW = 350W You are getting more than that - ...

I tried to get some numbers from your video but things are varying quite a bit and I don't know your Assist Start value so this is hard to evaluate. That said, it doesn't look very far off - not a factor of two. You indicated you were using Start Assist values in the 35HW - 65HW range. If you subtra...

Unfortunately, on my way home up the hill yesterday it seemed to be back to giving me half of the multiplier: Hmmm - that's interesting. Tracking down the exact cause of this last behavior may take a bit of digging. If possible, please PM me with a setup file and a couple of words to describe your ...

I've also noticed that the relationship between my human wattage and motor wattage being mismatched... I just upgraded to 3.11 and ... this seems to be fixed. Sorry your original post didn't get a response here in the thread, but your heads-up about the issue helped catch the cause during the 3.11 ...

I carry a few inches of Schwalbe SnakeSkin sidewall with the bead trimmed away from an old tire carcass to glue behind a slash - basically a rubberized densely woven nylon graft. I haven't used it on my bike but installed such a patch on a stranded cyclist slashed tire. It inflated fine, looked good...
