7) 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.
8) 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 - PG9).
9) THE ELECTRICAL PLANT SET-UP
Set the electrical plant (fig. 19) according to the current standards for electrical
plants. Keep the power supply connections definitely separated from the auxiliary
connections (photocells, rubber skirts, control devices, etc.).
Perform the connections of the control and safety devices in compliance with
the above mentioned standards.
Fig. 19 indicates the number of connections and the sections for 100 m. long power
supply cables. For distances of over 100 m., calculate the cable section depending
on the automation actual load. If the length of the auxiliary connections exceeds
50 metres or if they pass through critical areas subject to disturbances, we advise
to disconnect the control and safety devices with 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).
9.1) Automation main components (fig. 19)
I) Type approved omnipolar switch with 3,5 mm min. contact opening.
provided with overload and short-circuit protection, used to break the au-
tomation connection from the mains. If not present, provide 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.
10) ADJUSTING THE PUSHING FORCE
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 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 pre-
scribed by the regulations indicated above. 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 2-5 sec. ' s with respect to the time in which the leaves reach the
ground gate stops.
11) MANUAL OPENING
11.1) 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.
To restore the actuator to electrical operation, turn the key clockwise until pivot
"P" is locked.

INSTALLATION MANUAL
11.2) Versions without hydraulic lock
It is sufficient to open the electric lock with its key and move the leaf
manually.
12) COVER POSITIONS
The "C" cover of all LUX models can be changed from right to left by inverting the
position of the cap "T" (fig. 23).
To fit the bypass guard (fig. 24), place it in position and insert it under the rod
cover "C".
13) CHECKING THE AUTOMATION
Before considering the automation completely operational, the following checks
must be made with great care:
• Check that all the components are firmly anchored.
• Control that all the safety means work properly (i.e. photocells, pneumatic
skirt, etc.).
• Check the emergency manoeuvre control.
• Check the opening and closing manoeuvres using the controls.
• Check the control unit's electronic logic in normal (or customised) operation.
• Remove the bleeder screw.
14) 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.
15) 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 cha-
racteristics. For details on the various command systems, consult the specific
instruction booklets.
Anyone using the automation must be instructed in its operation and controls.
16) 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.
17) TROUBLE SHOOTING
17.1) 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.
17.2) 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
disconnected. For details on each component, refer to its specific instruction
manual.
WARNING: Any malfunction should be corrected immediately by a qualified
specialist. 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.
