Re: Adding PAS to EM3EV controller

I'd probably wire the PAS to these.
+5v red
GND 6 to black
TA to the other one

Re: Adding PAS to EM3EV controller

The following question is about pas connection without any display: Yes, I fully understand that Is the TA as seen (foto) there, is it compatible with my pas (standart) with magnets? Absolutely no way I can say for sure..the only way is to try it and see and risk damaging something if wrong. It pro...

Re: Adding PAS to EM3EV controller

I f you want to open your controller and look, you might be lucky... If it happens to be labelled PAS, then you'd need to solder a wire to that pad, and another from a 5 volt feed and another to ground Get it wrong and you will of course risk screwing the controller on that controller it was labelle...

Re: Adding PAS to EM3EV controller

]Thanks, but it's still not enough, one told me that if I'm wrong I could do damage, the socket of the controller where I should connect the 3 wires of the pas is this: 1 Battery Voltage Vcc-L (red (I think it's battery indicator, my 48v., and I do not need to use it) 2 GND / Shunt + ve (black) 3 S...

Re: Adding PAS to EM3EV controller

Exactly as Amberwolf says, you can’t connect it to the 6 pin CA connector It can only be connected to the dedicated PAS connector. If you don’t have one, as he says, there maybe a PAS pad on the board, but I’d guess that at your level of knowledge of this stuff, you have slim to zero chance of findi...

Re: Adding PAS to EM3EV controller

Too long ago to remember
But any PAS with 3 wires will be basic
Voltage in. Probably 5 volts
Ground
Signal out

Re: 9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

If it is dropping to low voltage then coming back up, then that is the Battery management system circuit board (BMS) within the battery pack shutting off the battery output when under load. Either because of too high current , possibly too high battery temperature, or most likely, one cell in the ba...

yes, I found the 20-200 volt optional reference too,
Wondering if a resistor mod does the swap to 200v ??

Re: Creating MOSFET switch to run lights Raleigh Trail XC

This has three wires. grad 12 volt Data line. The bike is 36 volt and there is no battery voltage at the display/ control unit. Only 12 vol tin and the data out. So it does seem that originally any light switching was done at the controller, but this controller does not appear to have that facility....

Re: Creating MOSFET switch to run lights Raleigh Trail XC

I had been told on the Pedelec forum that there was in fact an actual switch output of battery voltage on the board, and not via a switched encoded signal to the the controller to switch the light. The opinion was that some of the bikes with OEM lights did take power direct from the handle bar unit....

Trickle current for BMS balance charging

Can someone confirm what I am thinking ...regarding charging LiPo with a BMS with a single cell balancing current of 168mA (+/- 20mA). BesTech HCX-D131 If I want to ensure a nice balancing charge, I'd set up a charger to charge at that sort of current, so if I set a charge current of say 125mA I'd g...

Re: Timing Adjustment Tool

Just trying to figure out if hall timing shifts the phase waves relative to eachother No, or if it shifts all of them together. Based on your posts and others in this thread I think the former is the case, but I'm trying to confirm. Correct, it just shifts them all.... But the controller itself is ...

Re: Timing Adjustment Tool

The tool actually creates a synthisised hall signal..it does nto actually 'capture' and send out the original. Also it does actually 'advance' the timing..that would be impossible without the ability to see in to the future. In effect, it see s the incoming signals (it intercepts all three) then del...

Since it is a 'self learning' controller, that sort of rules out a wrongbwiring combo I'd have thought.
