OpERATING LIMITs AND WARNINGs
This geared motor has been studied and manufactured to activate bal-
anced sectional doors (pOWER35).
Before proceeding to install the system, make sure that the door is bal-
anced and slides well. Check that the ropes, the springs and the para-
chuting system are in good conditions. For doors that have not been
installed recently, check also all the other parts subject to wear and tear.
The above instructions are essential for the safety of the system and the
reliability of the operator.
INsTALLATION
Thanks to its versatility, this geared motor can be assembled not only on
the right-side or left-side of the door, but also horizontally or vertically
(fig. 2). The geared motor has been designed to directly activate the ca-
ble winding shaft of the door which must feature 1" diameter (25.4mm)
and should be provided of housing for the key. For cable winding shafts
having a different diameter, an adapter should be provided (item VN.A30
for diam. 30 shafts, item VN.A3175 for diam. 31.75 shafts, item VN.A40
for diam. 40 shafts).To fit the unit proceed as follows:
• Make sure that the distance between the cable winding shaft and the
surface to which the bracket should be fitted ranges between 82 and
150mm (as per fig. 3).
• Weld or fit the bracket S with screws to the surface.
• Insert the feared motor in the cable winding shaft.
• Tighten the screws inserting the tightening key C first.
To calculate the movement speed of the door, proceed as follows:
V(door speed) = d(diam. of cable winding drum - m) x 3.14 x 24 = m/1'
It is possible to use the geared motor by extending the motion to the
rope winding-up shaft by means of a chain (item VN.RM). The motion
can possibly be transmitted reduced or multiplied (item VN.RV) (fig. 4).
To calculate the movement speed of the door, proceed as follows:
V(door speed) = d(diam. of cable winding drum - m) x 3.14 x 24 x Z1 /
Z2 = m/1'
ADJUsTMENT OF THE LIMIT sWITCHEs
The geared motor is equipped with 4 microswitches: 1 is the opening limit
switch (red cam), 1 the opening over-travel (blue cam), 1 closing limit
switch (yellow cam) and 1 is at disposal of the accessories (black cam),
N.C. max. 3A, 24Vac/dc max. To adjust the cams proceed as follows (fig.
10):
• Put a screwdriver in the hole F to avoid the rotation of the shaft.
• Loosen the nut D to allow rotation of the cam with a very reduced
resistance.
• Manually move the door until it is almost completely close and adjust
the yellow cam.
• Repeat the operation while opening the door and adjust the red cam.
• Then position the blue cam so that it is activated slightly delayed with
respect to the red cam.
• Power the automatic unit and operate it (if it is a closing operation, invert
wires 1 and 3 of the motor power supply, fig. 6 and 7) while adjusting the
closing cam (yellow) with slight adjustments as per fig. 11.
• Slightly tighten nut D.
