INSTALLATION MANUAL
OPERATOR
1) GENERAL OUTLINE
Low-voltage operator (24V
) suitable for residential use. Designed for swing
gates having small-sized pillars. The operating arm, with its special antishearing
shape, allows the leaves to be manoeuvred even when the operator is positioned
well away from their fulcrum. The irreversible electromechanical gearmotor keeps
the gate locked in the closing and opening positions.
The release lever, fitted to the outside of each operator, allows the manual ma-
noeuvre to be carried out very easily.
ATTENTION!
The
VIRGO SMART BT A
model controller is not equipped with
mechanical torque adjustment. It is compulsory to use a control panel of the
same manufacturer, in compliance with the basic safety requirements of direc-
tives 2014/35/CE, 2014/30/CE, 2006/42/CEE equipped with appropriate electric
adjusment of the torque.
Before carrying out the manual manoeuvre make sure that this operation will
not create a dangerous situations.
Check in the relevant literature that the thermal field in the working area is suit-
able for the operator.
Make sure that the movement of the door does not cause entrapment risks
between the movable and fixed parts of the door.
If swing gates with built-in doors are used, the motor must not run when the
door is left open.
WARNING!
The operator must be installed by a qualified technician as special
safety components are used for every specific site and therefore safety depends
on installation.

3) OPERATOR INSTALLATION
3.1) Preliminary checks
Check that:
• The gate structure is sufficiently sturdy and rigid.
The fixing position must be worked out according to the leaf structure. In any
case, the manoeuvring arm must push against a reinforced leaf point. (Fig.C)
• The leaves can be moved manually along their entire stroke.
If the gate has not been installed recently, check the wear condition of all its
components. Repair or replace defective and worn parts.
Operator reliability and safety are directly affected by the condition of the
gate structure.
4) SUPPORT PLATE FIXING
The operator is supplied with a fixing bracket and lever arm.
Having identified the leaf reinforcement point, with the gate closed, trace an
imaginary horizontal line from the centre of the reinforcement point to the pillar
(Fig. D Ref.1).
Fig. C illustrates the most common types of installation:
Ref.2: 90° opening, position A and B as per the drawing
Ref.3: 90° opening, position B maximum
Ref.4: 120° opening, position A and B as per the drawing
Ref.5: 90° outward opening
See table for other installation positions and relative lever angles.
Position the fixing bracket respecting the positions in fig.C.
The pillar surface, where the bracket is fixed, must be flat and parallel to the leaf.
Use screws and expansion plugs adequate for the type of pillar. In the case where
the pillar surface is irregular, use expansion plugs with studs, in order to be able
to adjust the fixing bracket parallel to the leaf (fig.D Ref.4).
• Assemble the lever arm as in fig.E.
DX = fitting to right leaf
SX = fitting to left leaf
Choose the most suitable position for fixing bracket “F” to the leaf.
• Insert the lever arm “L” into the output shaft of the gearmotor and secure it
using the special pin “P” and the self-locking nut “D”.
• Release the actuator by operating the release lever to allow easy movement
of the arm (see paragraph “EMERGENCY MANOEUVRE”).
• Open the gearmotor cover and fasten it to the plate as shown in Fig.F Ref.1-2.
• Fix the leaf bracket Fig. F
• Fix the drive bracket “F” to the leaf.
• The correct position that the actuator arm must assume depends on the
installation.The attachment point to the leaf is ascertained by positioning the
arm in such a way as to respect the position shown in fig.C Ref.1.
• With the operator released, check the arm for correct movement.
• Repeat the same procedure for the other leaf.
5) LIMIT SWITCH ADJUSTMENT AND FIXING OF STOP BLOCKS.
The VIRGO SMART BT A actuator is equipped with limit-switch mechanical stop
blocks, which make the installation of ground stops unnecessary.
Adjust the limit switches as described in paragraph “Motor connection and limit
switch adjustment in the THALIA control panel section.
Referring to Fig. G, proceed as follows:
- Identify the opening and closing limit switch points and fix the stop blocks so
that the lever arm comes into contact
slightly after the limit switches have
been activated.
6) EMERGENCY MANOEUVRE (Fig.1)
In the case where the power supply is off, or any faults are present, the manual
emergency manoeuvre can be carried out by operating the external release
lever (Fig.1 rif.S).
1) Insert the release key and turn it anticlockwise (Fig.1 ref.B).
2) Move lever “S” until the lock is released (Fig.1 ref.B).
3) Push the leaf slowly to open or close the gate. (Fig.1 ref.C)
To reactivate motor-driven operation, turn the key clockwise to free the lever
from its released position, then return it to its initial position for normal operation.
7) MANUAL WIRE RELEASE DEVICE (Fig.H)
The manual emergency release can be operated by a wire device:
- Take all the metal cable out of the sheath and insert it into the release lever.
- Lock the sheath and suitably adjust its position by means of the appropriate
screw.
- The cover is provided with a section to be torn off for the sheath to go through.
- For further information, refer to the specific instructions for the release device.
8) AUTOMATION CHECK
Before allowing the automation to be used normally, carry out the following
procedure very carefully:
• Check the correct functioning of all safety devices (limit microswitches,
photocells, sensitive edges etc.).
• Check that the thrust (anti-squash) force of the leaf is within the limits set by
current regulations.
• Check the manual opening command.
• Check the opening and closing operations with the control devices in use.
• Check the standard and customised electronic functioning logic.
9) AUTOMATION OPERATION
Since the automation can be remote-controlled by means of a remote control
device or a start button, and so out of sight, the good working order of all the
safety devices should be checked regularly. In the event of any anomalous fun-
ctioning of the safety devices, consult a specialised technician immediately. Keep
children at a safe distance from the automation operation area.
10) CONTROL
The automation is used for the power-operated opening and closing of the gate.
The control can be of a number of types (manual, remote-controlled, magnetic
badge access control, etc.) depending on requirements and the characteristics
of the installation. See the specific instructions for the various control systems.
Users of the automation must be instructed about its control and operation.
11) MAINTENANCE
Disconnect the power supply when carrying out any maintenance operations.
• Lubricate the
VIRGO
s of the manoeuvring arm regularly.
• Clean the lenses of the photocells every so often.
• Have a qualified person (installer) check correct motor torque setting.
• In the event of any anomalous functioning which cannot be resolved, discon-
nect the power supply and contact a specialised technician (installer). Whilst
the automation is out of order, activate the manual release to allow manual
opening and closing.
