on my bac2000.But I cannot get it to connect to the pc at all

ive tried several usb rs485 cables tried different baud rates /com ports etc nothing works ?!
anybody solved this issue?
If your battery voltage isn't actually outside the foldback thresholds, this probably means that the "start" and "end" parameters are set to the same value. This is a common issue with the foldbacks in the ASI controllers - by default the start and end are the same, but this condition causes a warning. Note that these warnings won't actually affect the functioning of the controller, they're just annoying. But to clear them, just make sure the start and end are set to reasonable values, and that these values are different.nickjs wrote:Im getting the same warnings - VdcHighFLDBK and also VdcLowFLDBK.
I've never had trouble connecting, but here are some things to check:But I cannot get it to connect to the pc at all
Maybe a shot in the dark but I found one ground worked with RS485 and the other didn't. Which pin are you using for ground?nickjs wrote:Thanks cyborg that makes sense about the warning lights, ive tried your suggestions tx to Rx etc etc - still no luck, maybe my controller is damaged ?
Ive only tried rs485 on pins 10,11, and ground , also tried pins 12,13 and ground as reccommended by Asi still nothing . So next option is to try rs232 cable on pins 3,13 and ground , if that fails then .........?
I have never been able to communicate with any of our BAC2k via rs485 only rs232.nickjs wrote: I have only tried rs485 on pins 10,11, and ground , also tried pins 12,13 and ground as recommended by Asi still nothing .

Don't know your adapter specs, but if orange is RX and yellow is TX, this should work.nickjs wrote:ftdi ---- bac2000
orange -- pin 3 (yellow/black)
yellow -- pin 13 (grey black)
black -- pin 14 (black)
I think it would work if you set the PR's battery limits wide enough to accomodate both batteries, then run the throttle through the CA and set the battery coutout on the CA.Tats wrote:Quick question - I have a phaserunner and CAv3 - Can I run different voltage batteries (A & B) and switch between them using the CA only? I recognise I'd probably have to disable regen on the PR?
Or ,would I need to connect the PC and change the PR settings as per section 4.2 of the manual each time I wanted to use the different voltage battery?
The CA3 can be adjusted to avoid 'cutout' in near-discharged situations.cycborg wrote:If it were me, I'd really miss the "foldback" behavior of the PR, as opposed to the "cutout" feature of the CA.
In addition to that Lisa,try reducing the max throttle input voltage to like 3 or 3.5V to ensure that you are commanding the 100% phase current capability, right now you have it set to 4.2V throttle signal for 100% phase current. The Phaserunner has some internal resistors that mean the voltage fed into the throttle plug can be read by the phaserunner chip at a lower value, so for instance you can have 4.0V on the throttle pin but the phaserunner's microchip might only be seeing more like 3.6V or so. You can use the dashboard tab on the setup utility and see what the actual throttle input span is from the phaserunner's perspective and set the throttle range accordingly.Tats wrote:Hi Lisa, On my H3540 I have set my PR to 96a phase current and 50ms torque upramp in the PR setup (basic set up screen bottom right section) - made things a little more brisk.
Cycborg is exactly right here. Set the max regen voltage on the Phaserunner suitable for the higher of the two battery packs, and use the CA's battery A and B presets to have separate low voltage rollbacks on each pack. It's the low voltage rollback that actually comes into play on a regular basis when riding, and as Teklektik clarified the CA will let you have a gradual power reduction instead of a hard cutoff from letting the BMS trip.cycborg wrote:I think it would work if you set the PR's battery limits wide enough to accomodate both batteries, then run the throttle through the CA and set the battery coutout on the CA.Tats wrote:Quick question - I have a phaserunner and CAv3 - Can I run different voltage batteries (A & B) and switch between them using the CA only?

I like those too. I think there is a larger MT90 version as well. These are also good for connectorizing the phase wires coming out of a hub motor to make for easier tire repairs.jonescg wrote:I'm excited by those MT60 plugs - they look perfect for the job. We've long wanted a compact 3-way connector with enough meat to handle a hundred amps or more.
I wouldn't worry too much about electrical insulation, they're all pretty good in that regards unless you are talking something with metal filler (or perhaps you are still dealing with 700+ volts?!). In the end what became the driving priority for our resin selection was very low mixed viscosity so that we could fill the phaserunner molds without air entrapment, and a reasonably low cured hardness spec so that the epoxy wouldn't be brittle in cold weather or stress the internal electronics too much. Thermal conductivity wasn't much of a concern since all the heat flow from the FETs is directly through the aluminum heatsink that is directly exposed to outside air and making physical contact to the metal bike frame.jonescg wrote: Justin I'm keen to know which potting epoxy you are using. I've been looking around for an epoxy which is reasonably heat conductive but very electrically insulating. I found some material with a thermal conductivity of 2.16 W/m.K which is pretty good for an electrical insulator.
