4. OUTSWING DOOR ARM INSTALLATION
Use the WELBA outswing door arm for doors that open outwards
as seen from the geared motor side.
Fasten the base plate [9] to the wall so it is stable and level using
the measurements indicated in the figure.
Also drill a hole in the door wing where the articulated arm is
to fixed.
(*) If necessary use the WELD40 extension to lengthen the
measurement between the automation and the arm to 70 mm.
WEL - IP1891
Reposition the components on the base plate.
Note: in the version with the WELBA jointed arm, the motor must
again be positioned on the hinge side.
Check that the jointed arm is properly assembled (see prepa-
ration in chapter 4.1).
Fix the arm to the automation at point [A]. Also fix the top end
of the arm to the door wing, in such a way as to create an angle
of 90° as shown in the figure.
The manual opening force can be reduced for the LOW ENERGY
applications by reducing angle α and following the measuremen-
ts indicated in the figure.
Note: for distances between the automation and the door wing
lower than 115 mm it is necessary to shorten the non-drilled
side of the arm [B].
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.
