Docking system stuck in scenery


I have used VGDS tweaker to creater my MDL for a SafeGate docking system. Then converted it into a RWY12 xml file and added it to my bgl.

Fine, the system appears right but it seems not to be activated as only TOO FAR is flashing while STOP is constantly lit. No other movement was found...

Have I done something wrong in compiling ?

Thanks for your help, Brgds
