Reposition the components on the base plate.
Note: in the version with the WELBRAS jointed arm, the motor
must always be positioned on the side opposite the hinges.
Check that the WELBRAS arm is properly assembled (see
preparation in chapter 6.1).
Fix the arm to the automation at point [A]. Fix and regulate the arm [B]
in such a way as to form an angle of 80° - 90° as shown in the figure.
If necessary remove the arm [B] and join the WELBRAS arm
using the spacer and screw provided.
Important: fixing the arm to the door wing for automation with
a WELS and WELE closure spring, is difficult because of the
thrust of the spring.
Move the door manually and check that it opens and closes
properly without friction. Install the open door stop.
Note: the floor stops must be fastened in a visible position so
there is no risk of people tripping over them.

6.1 Preparation of the WELBRAS arm

If necessary, reverse the WELBRAS arm assembly as indicated
in the figure in the direction the door opens.
