 The control units are also different (CDK for the type-approved version and CDK-US for the normal version) and in certain situations they function differently (e.g. : in the event of a blackout, the post of the type-approved version descends automatically, and if the power is restored it continues to descend, while the post of normal versions tend to descend and, if the power is restored it stops, as the electric lock is re-enabled).
There are also mechanical differences; the type-approved version has a reinforced rod and highly reversible worm screws.
