BFT LUX are hydraulic operators and as such, the control board should not electronically adjust force or speed (inc. slowdown) as evident in the table I mentioned (see the different values, in a number of options, between hydraulic and electromechanical operators). However, if the installer has selected the right operator (operators for especially wide leafs must be slower because the velocity of the leaf edge, for a given operator, increases proportionally with leaf width). and has properly installed it (especially in regards with the position of the rotation point of the operator in regards to the gate hinges - dimensions a & b, page 4 of http://manuals.easygates.co.uk/PDF/bft/LUX/LUX.pdf ) the velocity of the edge of the leaf shouldn't be too high. Only other thing you can do AFAICT is installing pieces of rubber to the stops or leafs to cushion the impact.
