4.2 - Electrical connections

Remove the protective chain guard from the micro switches
Insert the cable into the cable conduit and carry out the connections.
It is important to respect the motor common wire (COM) and it is
fundamental to carry out the ground link.

4.3 - Direction test and adjustment of the closing limit switch

To position the closing limit switch (see Figure 5 Ref I), proceed as
follows:
Release the regulator by pulling gently on the pin at the side (see Fig.
5b).
Once freed the regulator, turn it towards the micro-switch until you
hear the opening click of the micro-switch contacts (see Fig 5 Ref C).

4.4 - Adjusting the opening limit switch

Once the closing limit switch has been set correctly and its operat-
ing direction has been checked, the opening limit switch must be
positioned correctly. To adjust it, pull the pin at the side as before
(see Fig. 5b) then turn the regulator towards its microswitch, setting
them close together. Lock the regulator in place by pressing the two
halves together (see Fig. 5c). Check that the regulator will not turn!

Lock the regulator again by pressing the two halves together (see
Fig. 5c). Check that the regulator will not turn!
Switch the machine on and if the motor does not turn over the con-
nection is correct, otherwise disconnect the supply and invert the
cables connected to the terminals or the two cables connected to
the motor.
The position of the common wire must never be changed.
Power the motor and let the shutter roll up until it stops. In case of
unsuitable opening, return the shutter in the closed position and act
again as previously described, approaching or moving away the
regulator from the position previously laid down.
The white lines silkscreened on the circuit are specially placed to
assist the user in positioning the opening limit switch.
