It's implemented and dependend of presure in brake cylinder.
Here's part of the code:
if (DynamicBrakeType=dbrake_automatic) thenSo you have to have converter on and have preassure in brake cylinder over 0.25 bar caused by continous brake.
if (((Hamulec as TLSt).GetEDBCP<0.25)and(Vadd<1))or(BrakePress>2.1) then
else if (BrakePress>0.25) and ((Hamulec as TLSt).GetEDBCP>0.25) then
DynamicBrakeFlag:=DynamicBrakeFlag and ConverterFlag;
