ATM I have it set SW1 + SW2 on and S4 set high.

the 19.5kg works fine but the 21.0 KG only goes in one direction.

This will be an obvious problem to folks on here but I'm scratching my head.

I know its the current setting.. well I think that's where I should start but not sure what I'm doing.. any help :) ?
