I think i have a setting somewhere that needs changing on the LCD8H.

Bafang 48v Swx02 from Woosh
KT LCD8H

Everything was working fine with the KT 15a controller. PAS worked fine in one direction.

I changed my controller from a 15a Kt controller to a 17a KT controller. I checked the settings and everything was still the same on the KT display.

However the pas stopped working, without checking the pas settings again on the LCD i changed the PAS sensor. Left the 10 ring magnet as it was.

However now the PAS was working on/off so i took a look at the lcd settings and noticed C1 was 5. I went through all the C1 settings and settings 3 and 4 worked the best so i lefi t on 3. However now even if i pedal backwards this activates the PAS. I tried setting 4 but this had the same issue. I did not try any other setting as this makes the PAS behave erattically.

Is there any other settings related to the PAS?

I have attached a picture of my LCD settings.

It is simply down to the Hall sensor used in the PAS sensor some work both ways, which is a bit annoying if one pushes the bike backwards or back pedals. I had one like that and simply set C8/0 so that the PAS level defaulted to 0 when screen is turned on otherwise I always made sure PAS level was 0.

Yes that makes sense.

The one I replaced was a king meter one with a little led light on it. Only activated going forward.

I will do the setting as you said.
