of travel is maintained in the rod. This margin prevents any malfunctions.
6) FITTING THE ELECTRIC LOCK
This is only necessary on models without a hydraulic lock at closing end of stroke.
The electric lock mod. EBP (fig. 17) consists of a continuous electromagnet with ground
catch. As long as the gearmotor is operating, this device features a non-stop excitation
and maintains the bolt "D" lifted until it reaches the closing end of stroke without creating
any friction. This characteristic enables the pushing force to be reduced in closing which
will improve the antisquash safety level.
7) MOUNTING THE CABLE-CLAMP (fig. 18)
WARNING! Fix the board "B" to the base "F" with the screws "V" provided. Place the rubber
"G" in its seat in the board "B". Slide the nut "D" onto the power cable and pass the cable
over board "B" as shown in the picture Tighten nut "D" until the power cable is clamped.
N.B. The board "B" can be fitted onto both the right and left of the base "F", as required
(see picture).
The bottom of board "B" has a spiralled recess to eventually receive a spiralled sheath
"GS" in PVC (Ø = 12).
8) THE ELECTRICAL PLANT SET-UP
Set up the electrical installation as shown in fig.19, making reference to the current stan-
dards for electrical installations. The mains power supply connections must be kept totally
separate from the service connections (photocells, electric edges, control devices etc.).
Warning! For connection to the mains, use a multipolar cable having minimum
3x1.5mm (16AWG) cross section and complying with the previously mentioned
2
regulations (UL1015).
Connect the control and safety devices in compliance with the previously
mentioned electrical installation standards. Fig.16 shows the number of connections
and the cross section for power supply cables having a length of approximately 328 ft
(100 metres); in case of longer cables, calculate the cross section for the true automation
load. When the auxiliary connections exceed 164 ft (50-metre) lengths or go through
critical disturbance areas, it is recommended to decouple the control and safety devices
by means of suitable relays.
The connector blocks for the power supply must be placed at a height greater than
that of the actuators so as to avoid oil leakages (Fig. 19).

provided with overload and short-circuit protection, used to break the

automation with a type approved differential switch with adequate
capacity and a 0.03 A threshold.

IMPORTANT: Before operating the actuator electrically, unscrew the bleeder screw
"S" (fig. 20)found under the joint block and keep it for future uses. Remove the
bleeder screw "S" only after having installed the actuator.
9) ADJUSTING THE PUSHING FORCE
The adjustment is made by two valves marked "close" and "open" which control the
pushing force during closing and opening respectively.
By turning the valves towards "+", the force is increased, while by turning them towards
"-" it is reduced.
To ensure an adequate antisquash safety, the pushing force must be adjusted to just
over the push needed to move the leaf, both in closing and opening. In any event, the
pushing force at the end of the leaf, must not exceed the limits prescribed by current
national regulations. For no reason should the adjustment valves (bypass) be fully closed.
The actuator does not have electric limit switches. Therefore the motors stop when the
working time set in the control unit has expired. The time set must be increased by 2-3
sec. ' s with respect to the time in which the leaves reach the ground gate stops.
10) MANUAL OPENING
10.1) Versions with hydraulic lock
In case of emergency, for example during a power cut, the gate can be released by
inserting the same key "C" used to adjust the bypass valve into the triangular pivot "P"
found under the actuator (fig. 21) and turning it anti-clockwise. The gate can then be
opened manually following the same speed as an automatic opening.
INSTALLATION MANUAL
To restore the actuator to electrical operation, turn the key clockwise until pivot "P" is locked.
10.2) Versions without hydraulic lock
It is sufficient to open the electric lock with its key and move the leaf manually.
11) COVER POSITIONS
WARNING: In the LUX G models, it may be necessary to add a 25 mm lining under the
fork "F" (fig. 23) to avoid any collision during the movement, The "C" cover of all LUX
models can be changed from right to left by inverting the position of the cap "T" (fig. 24).
To fit the bypass guard (fig. 25), place it in position and insert it under the rod cover "C".
12) USE OF THE AUTOMATION
Since the automation may be remote controlled either by radio or a Start button, it is
essential that all safeties are checked frequently.
Any malfunction should be corrected immediately by a qualified specialist.
Keep children at a safe distance from the field of action of the automation.
13) THE CONTROLS
The controls can come in various forms (i.e. manual, remote controlled, limited access by
magnetic badge, etc.) depending on needs and installation characteristics. For details
on the various command systems, consult the specific instruction booklets.
Anyone using the automation must be instructed in its operation and controls.
14) MAINTENANCE
All maintenance on the controller must be performed with the system's power supply
shut off.
- Check periodically for oil leaks. To top-up the oil proceed as follows:
a) Screw in the bleeder screw (fig. 20) and remove the controller from the gate.
b) Push the rod right back.
c) Set the controller upright and unscrew the cap O (fig. 18).
d) Use the same type of oil to top up the level until the motor bearing under the cap
"O" is covered.
e) Close the cap "O" and mount the controller back onto the gate.
f) Remove the bleeder screw.
g) Run through 2 complete manoeuvres collecting the excess oil from the bleeder.
• Check the safety elements on the gate and drive unit.
• For any malfunction that remains unsolved, shut off the power to the system and
call a qualified specialist (the installer). During a breakdown, use the manual release
to allow the gate to be opened and closed by hand.
15) TROUBLE SHOOTING
15.1) Faulty operation of the gearmotor
• Use a suitable instrument to check if there is a voltage across the gear motor terminals
when an open or close command has been given
• If the motor vibrates but does not turn, this may be due to:
• the common wire C is wrongly connected (it is always light blue)
• the drive capacitor is not connected to the two drive terminals
• if the leaf moves in the wrong direction, invert the drive connections of the motor
in the control unit
LEAF STOP: when the operating time set in the control unit is too short, the leaves may
not have time to complete their stroke. Slightly raise the operating time in the control unit.
15.2) Faulty operation of the electrical accessories
If any of the control and safety components are faulty, this can cause malfunctions or a
breakdown of the whole automation.
If the control unit is equipped with a self-diagnostics system, identify the fault.
In case of a fault, it is wise to disconnect each of the components in the automation one
at a time, until the one that is causing the fault is found.
After having repaired or replaced it, restore all the components that were discon-
nected. For details on each component, refer to its specific instruction manual.
WARNING:
When carrying out maintenance operations, the area around the gate should be well
marked and barred in order to prevent accidents to people, animals and objects.
WARNINGS:
Trouble-free operation of the controller can only be guaranteed if the data given in this
manual is respected.
The manufacturer is not liable for damages caused by the failure to respect safety rules,
installation recommendations and instructions given in this manual.
Any malfunction should be corrected immediately by a qualified specialist.
