• Before installing the automatic system read the instructions
hereunder carefully.
• It is strictly forbidden to use the product VN.S for applications
other than indicated in this instruction handbook.
• Show the user how to use the automation system.
• Give the user the part of the leaflet which contains the instructions
for users.
• All Benincá products are covered by an insurance policy for any
possible damages to objects and persons caused by construc-
tion faults, under condition that the entire system be marked CE
and only Benincá parts be used.
OPERATiNg LiMiTS AND WARNiNgS
This geared motor has been studied and manufactured to activate
balanced sectional doors (VN.S20/VN.ST20) as well as rolling doors
(VN.S40/VN.ST40).
Before proceeding to install the system, make sure that the door
is balanced and slides well. Check that the ropes, the springs and
the parachuting 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
(fig. 2) or vertically (fig. 3). The geared motor has been designed
to directly activate the cable 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 (fig.4):
• Check that the distance between the rope coiler shaft "A" and
the surface onto which brackets should be fitted ranges between
82 and 150mm.
• Weld or fit the bracket "S" to surface with screws.
• Introduce the gear motor in the rope coiler shaft, while interposing
the key "C".
• Tighten the fitting screws "V".
• To mount the plate on side "B", use screws TE M10x20 sup-
plied.
To calculate the movement speed of the door, proceed as fol-
lows:
V = 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. 5).
To calculate the movement speed of the door, proceed as fol-
lows:
V = d (diam. of cable winding drum - m) x 3.14 x 24 x Z1 / Z2 = m/1'

VN.S20/VN.S40: The 25µF capacitor must be connected to the
motor terminals 7 and 8 of THINK control unit.
To use the micro-switch supplied as a safety limit switch in the
closing phase, modify the cable positions as per fig. 7.
N.B.: Models 400V three-phase can be used also at 230V three-
phase by changing from a star connection to a triangle one as per
fig. 8.
ADjuSTMENT OF THE LiMiT SWiTCHES
The geared motor is equipped with 4 microswitches:
Red limit switch Opening limit switch (SWO)
Blue limit switch Opening over-travel (SWO XT)
Yellow limit switch Closing limit switch (SWC)
Black limit switch At disposal of the accessories (AUX)
To adjust the cams proceed as follows:
• Manually move the door until it is almost closed and adjust the
SWC cam until the micro-switch is almost triggered (Fig. 9).
• Tighten the dowel shown in Figure 10 by using a 2.5mm socket
head key.
• By using the same key, carry out the micrometric adjustment of
the cam, as shown in Figure 11.
• Repeat the operation while opening the door and adjust the SWO
cam.
• Then position the SWO XT cam so that it is activated slightly
delayed with respect to the SWO 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).
• Should further adjustments be required, turn the micrometric
adjustment dowel.
Figure 12 shows the wire diagram of limit switches in single-phase
motors, while Figure 13 shown wire connections in three-phase
motors.
