ENGLISH
that the automation operates electrically.
• Put the actuator door key away in a safe place known to the operators.
16) AUTOMATION TESTING
Before the installation is made fully operational, carry out the following
checks.
• Check that the overload cutout (fig.22 – ref. "SM") is set for the rated
current absorbed by the motor (400V / 2.8A) -(230V / 4.84A).
• Check that all safety devices (limit microswitches, photocells, electric
edges, etc.) operate correctly.
• Check the tightening torque of the pinion release (emergency release).
• Check that the leaf stops within the time and limits provided for by
current prescriptions.
• Check that the rack-pinion mesh is correct (4mm minimum play).
• Check that the opening and closing end-of-stroke runners are correctly
positioned and secured.
• Check the start and stop operation in case of manual control.
• Check the start and stop operation in case of remote radio control.
• Check the normal or customised function logic.
• Check that all components are tightly secured.
• Apply the danger warning label (fig. 23).
17) CONTROL
The use of this control device allows the gate to be opened and closed
automatically. There are different types of controls (manual, remote,
magnetic badge access control, etc.) depending on the installation require-
ments and characteristics.
For the various control systems, refer to the applicable instructions.
Explain the correct operation of the automation device to the end
users.
18) Maintenance
WARNING! Any maintenance operation must be carried out by qualified
personnel (see paragraph 2).
• Check the play between the pinion and rack (4mm c.a.). Moderately
clean and grease the rack.
• Always keep the sliding track clean and free from debris.
• Occasionally clean the photocell optical elements.
• Check the correct tightening torque of the pinion release screw.
• When any operational malfunction is found, and not solved, disconnect
the mains power supply. When automation is out of order, activate the
emergency release (see paragraph "EMERGENCY RELEASE") so as
to put the pinion in neutral and allow the gate to be opened or closed
manually.
19) NOISE
The aerial noise produced by the gearmotor under normal operating
conditions is constant and does not exceed 70dB(A).
20) SCRAPPING
Materials must be disposed of in conformity with the current regulations.
In case of scrapping, the automation devices do not entail any particular
risks or danger.
In case of materials to be recovered, these should be sorted out by type
(electrical components, copper, aluminium, plastic etc.).
21) DISMANTLING
When the automation system is disassembled to be reassembled on
another site, proceed as follows:
• Disconnect the power supply and the entire electrical installation.
• Remove the gearmotor from its fixing base.
• Disassemble the control panel, if separate, and all installation compo-
nents.
• In the case where some of the components cannot be removed or are
damaged, they must be replaced.
22) MALFUNCTION: CAUSES AND REMEDIES.
22.1) The gate does not open. The motor does not turn.
1) Check that the system is supplied with power (see main switch).
2) Check that the door safety microswitch operates correctly.
3) Check that the overload cutout located inside the control panel has not
been activated; if necessary, restore operation using the appropriate
button and check current absorption by means of amperometric pliers.
4) Check that the photocells or electric edges are neither dirty nor
engaged nor misaligned. Otherwise proceed accordingly.
5) Check that the electronic equipment is correctly supplied with power.
Check that the fuses are not damaged.
6) By means of the control unit diagnosing LEDs (see respective
instructions), check that the functions are correct. If not, identify the

cause of any fault. If the LEDs show a persistent unwanted start
command, check that there are no radio controls, start buttons or other
control devices keeping the start contact activated (closed).
7) If the control units does not work, replace it.
22.2) The gate does not open. The motor turns but there is no
movement.
1) The manual release was left activated. Restore motorised operation.
2) Check whether the gate is well housed in the mechanical end-of-stroke
stops.
Release the gate manually, move it from its position and restore
motorised operation. Check and correct the position of the end-of-
stroke runners to anticipate microswitch intervention. If after electric
stoppage there is excessive leaf sliding, check the electric brake air
gap, as specified in the motor instruction manual supplied with the
product.
3) Check that the gate does not show mechanical defects, as for example
wheels blocked, pinion/rack misaligned, etc.
4) If the motor turns, but the leaf is not strong enough to move, check that
there are no oil leaks in the coupling, and check the oil level in the
hydrodynamic coupling, as explained in the instruction manual for the
coupling.
5) Any abundant oil leak may indicate that the hydrodynamic coupling
thermal protection has been triggered. Find the hidrodynamic coupling
oil plug, the appropriate type of oil and proceed as follows:
Disconnect the mains power supply.
Remove the box.
Remove the actuator from its fixing base and lay it down tilted to the
right with the motor in a horizontal position.
Rotate the hydrodynamic coupling by hand until it shows the green
thermal plug (fig.24 ref. TV) to be replaced.
For maintenance and repair, carefully read the hydrodynamic coupling
instruction manual supplied with the product, and follow the relevant
instructions.
Reposition the actuator in the base plate, align and secure it.
Refit the box, the doors and then recheck operation.
