Preparation Of The Welbras Arm - DITEC WELM Manual De Instalación

Fasten the base plate [9] to the wall so it is stable and level using
GB
the measurements indicated in the figure.
Also drill a hole in the door wing where the WELBRAS arm is
to fixed.
The fixing distance of the WEL automatic mechanism from the
door can be up to 185 mm towards the outside or can reach up
to 45 mm towards the interior as shown in the figure.
(*) If necessary use the WELD40 extension to lengthen the
measurement between the automation and the arm to 90 mm.
WEL - IP1891
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.
7. REGULATION OF THE OPEN LIMIT SWITCH
Connect limit switch FA as illustrated in the electronic control
panel manual. Move the position of sliding block [D] so as to
activate the opening limit switch FA before the opening stop.
Warning: the FA limit switch is optional for the WELM and WELS
automations.
Note: if the limit switches are positioned in the upper part of the
gearmotor, make sure that a sufficient distance is maintained to allow adjustment.
