WARNING: If the opening direction is not correct, invert the motor
connections no. 3 and 5 and connections no. 11 and 12 of the opening and
closing limit switches.
13) MOTOR TORQUE SETTING (SAFETY CLUTCH)
WARNING: Check that the impact force value measured at the
points established by the EN 12445 standard is lower than that
specified in the EN 12453 standard.
The setting must be carried out according to whatever is provided for by the
current safety standards. For this purpose, the motor torque needs to be set
in the following way:
•
Disconnect the mains power supply.
•
Remove the screws securing the gearmotor guard.
•
Use the fixed key provided to lock the motor shaft (fig.17 - ref. "A"). Using
the release knob, screw the self-locking nut (fig.17 - ref. "D") to increase
the torque, or slacken it to decrease the torque.
•
Reconnect the power supply and, with the help of a torquemeter, check
that the motion stops at the mechanical resistance values set out by the
current standards.
•
Put the protection guard back on the gearmotor and secure it with its
screws.
DANGER - The torque regulator must be calibrated before the
automation system is made to be operational.
14) EMERGENCY MANOEUVRE
Manual leaf opening is to be carried out in case of power supply failure or
automation inefficiency. Two types of knobs are available:
A) Pull-out knob
B) Personalised key-knob
Knob "A" (fig.18)
•
Insert the release knob in the appropriate seat, and rotate it clockwise
along its entire travel.
•
Push the gate leaf by hand.
•
In order to reset motor-driven operation or keep the gate locked on closing,
rotate the knob anticlockwise along its entire travel, move the leaf by hand
until it reaches its dragging point, remove the knob and keep it in a place
known to all users.
•
When the power supply comes back on, the automation device will resume
motor-driven operation.
Knob "B" (fig. 19-20)
In the case where a locking knob with a personalised key (fig.19-20) is used,
proceed as follows:
•
Insert the personalised key (fig.19) in knob lock, and rotate the knob
anticlockwise until a click is heard.
•
Rotate the release key clockwise along its entire travel (fig.20).
•
Push the leaf by hand. The personalised key cannot be pulled out until
motor-driven operation is reset.
•
In order to reset motor-driven operation, rotate the knob anticlockwise,
and rotate the key clockwise until it comes out.
•
Keep the key in a place known to all users.
15) INSTALLATION CHECK
Before the automation device finally becomes operational, scrupulously
check the following conditions:
•
Check that all the safety devices (limit microswitches, photocells, electric
edges etc) operate correctly.
•
Check that the rack and pinion are correctly meshed (minimum play 2mm).
•
Check that the pushing force of the gate is within the limits provided for by
the current standards.
•
Check that the opening and closing end-of-stroke runners are correctly
positioned and tightly secured.
•
Check the starting and stopping operations using the manual control.
•
Check the starting and stopping operations using the remote radio control.
•
Check the normal or customised operation logic.
16) AUTOMATION DEVICE USE
Since the automation device can be controlled both remotely and in sight,
by means of a radio control device or a button, all the safety devices must
be frequently checked in order to ensure their perfect efficiency.
WARNING! In the event of any safety device malfunction, request
immediate assistance from qualified personnel. Children must be
kept at a safe distance from the automation operation area.
17) AUTOMATION CONTROL
The use of this control device allows the gate to be opened and closed
automatically. There are different types of controls (manual, radio control,
magnetic card access etc.) depending on the installation requirements and
characteristics. For the various control systems, see the relevant instructions.

INSTALLATION MANUAL
The installer undertakes to instruct the user about correct automa-
tion operation, also pointing out the actions to be taken in case of
emergency.
18) MAINTENANCE
WARNING! Before proceeding to any maintenance, disconnect the
mains power supply and, if the battery is fitted, one of its poles.
These are the check and maintenance operations to be carried out:
•
•
•
•
19) NOISE
The environmental noise produced by the gear-motor in normal operation
conditions is constant and does not exceed 70 dB (A).
21) SCRAPPING
Materials must be disposed of in conformity with the current regula-
tions.
In case of scrapping, the automation devices do not entail any particu-
lar risks or danger. In case of materials to be recycled, these should be
sorted out by type (electrical components, batteries, copper, aluminium, plastic
etc.).
20) DISMANTLING
When the automation system is disassembled to be reassembled on
another site, proceed as follows:
• Disconnect the power supply and the entire external electrical installation.
• In the case where some of the components cannot be removed or are
21) MALFUNCTION: CAUSES and REMEDIES
21.1) The gate does not open. The motor does not turn.
1) Check that the photocells or the sensitive edges are not dirty, engaged,
2) Check that the electronic appliance is correctly supplied. Check the
3) Check that the functions are correct by means of the control unit diagnosing
4) If the control unit does not work, it must be replaced.
21.2) The gate does not open. The motor turns but the movement does
not take place.
1) The manual release is activated. Reset the power-driven operation.
2) Check that the gate had reached the mechanical end-of-stroke stops.
3) Check that the mechanical setting of the gate is not defective, for example
4) Check that the clutch does not slip. If it does, load it as described in the
WARNING! Correct controller operation is only ensured when the data
contained in the present manual are observed. The company is not to
be held responsible for any damage resulting from failure to observe
the standards relating to safety, installation and good technical
practice, as well as the instructions contained in the present manual.

Check the condition of lubrication of the metal racks once a year.
Keep the sliding track always clean and free from debris.
Occasionally clean the photocell optical elements.
Have a qualified technician (installer) check the correct torque limit
setting.When any operational malfunction if found, and not resolved,
disconnect the mains power supply and request the assistance of a qualified
technician (installer). When the automation controller is out of service, you
can activate the manual release device (see paragraph on "Emergency
manoeuvre") in order to set the pinion idling and therefore allow the gate
to be opened and closed by hand.

Identify causes for faults, if any. If the LEDs show persisting start control,
check that no radio controls, start buttons or other control devices keep the

If after having carried out the checks listed above the problem persists,
replace the actuator.
Release and move the gate manually, and reset the power-driven control.
Check and correct the end-of-stroke bracket position.
