Note. To ensure the full closing and opening of the gate, it is necessary to increase the manoeuvring times by 5
seconds.
There are time slots throughout the day, where vehicle trac is very high. Calculations should be made during that
time period.
Example.
What is the maximum working time for a gate that has a pause time of 20 seconds, and a time between full cycles
of 30 seconds?

EXAMPLE (STANDARD)
EXAMPLE (SPECIAL DIMENSION)
We are occasionally forced to vary the standard dimensions for reasons of space when placing the supports The above graphs refer to the
both automatic models (240-280) and when the opening is inwards.
The gates’ opening degrees are shown at the top of each of the graphs, from these values a cross section line emerges on which dimensions
A and B may be obtained (Fig.2 Page 5). It is important to be as close to the thick vertical line as possible.
Dimension C remains constant in both motors, model 360 C=90 mm, model 280 C=80 mm and model 240 C=70
Example: What would be the dimension A and what engine should I use to automate a gate with a 100° opening where B=140 mm?
A motor with a 360 mm stroke length and dimension A=195 mm. (see example in graph of the 360 with thick discontinuous line, special
dimension).

ASSEMBLY INSTRUCTIONS

1. Place the pillar support (Fig.1) by trimming or supplementing the support according toAand B dimensions
of the table on Page 5. Determine the height of the support where the gate has a rigid surface to secure the
front support, taking into account that there is a 15 mm gap between supports (Fig.1 Page 5).
2. In this step we will proceed to the electrical installation of
the device.
Connect the terminals according to the following diagram:
3. Trim or supplement the gate support according to dimension C of the table on Page 5. Position the motor
with the front support, with the rod fully extended (Fig.2) and the ball joint threaded to the maximum
(Fig.3). Once the previous steps have been completed, balance the motor and with the help of a spirit level
(Fig.4) mark the position of the support on the gate and attach it to the mark made.
4. Assemble the motor and unscrew the ball joint about 3 turns to secure the closure, place the safety ring,
insert the gasket and secure the ball joint with the nut to the support. (Fig.6).
5. Manually operate the gate and open it to the desired position. Slide the limit switch ring over the rod
(Fig.9) to the front cap, and fasten it with the Allen screw. Now we can activate the motor electrically.
Reposition the ring if the opening is not as desired.
6. Once the motor is working correctly, proceed to adjust the limiters (Fig.10). The limiters are in charge
of controlling the force of the device, and are independent in the opening (blue limiter) and closing (red
limiter) manoeuvres. The screws will be handled with rotations of a maximum of 45°.
Proper force adjustment reduces the risk of damage to the installation and users.
7. Then adjust the soft closing stop (Fig.11). This valve is in charge of controlling the speed of the device
before completing the closing manoeuvre, avoiding annoying bumping from the door.
The manipulation will be carried out with rotations of a maximum of 10°, if we close this valve completely,
the soft stop is lost (15 mm).
8. Finally, the rod cover and the case cover will be press-tted (Fig.12).
ACTIVATING THE HYDRAULIC LOCK
When the actuation of the door lock is hydraulic we have to take into account the type of door opening;
- For inwards opening (Fig.2 of Page 5)
we must connect the hose at the output of the
1/8 G device in position 2.
- For outwards opening (Fig.3 of Page 5)
we must connect the hose in position 1.

LOCKING OPERATION
The BAC system incorporated in the ECO device oers a wide variety of possibilities. Here is how it should
be manipulated to get the most out of its performance.
EMERGENCY UNLOCKING
This valve allows us to perform the general unlocking to be able to
operate the door manually in the event of a power outage. To move the
door manually, simply turn 360° counterclockwise.
IMPORTANT: If the valve is not tightened (clockwise) the motor
does not run.
IMPORTANT: The partial opening of these valves works as an excellent windproof, and the hardness of
the gate may be adjusted with the motor at rest.
The gate requires a lock for gates that are longer than 1.8 m!

ANTI-CRUSHING SYSTEM
Fig.1
Fig.2
Fig.3
The anti-crush system oers great security throughout the gate’s path,
both when closing and opening.
PRESSURE SWITCH CONNECTION
To access the connection and regulation of the pressure switch remove
the screws located at the rear holding the cap of the pressure switch.
The pressure switch is a normally closed contact (NC), which opens
when the pressure regulated by the adjustment screw is exceeded.(Fig.
1 No. 1)
The system consists of two pressure switches (Fig.1), which are
responsible for controlling the circuit pressure of both manoeuvres
independently when opening and closing. These are connected in series.
(Fig.2-Fig.3). The connection of the pressure switch signal to the control
panel is made through the two-joint strip (Fig.1 No. 2) to the safety
contact inlet of the panel.
It is necessary to incorporate a limit switch in the closure, normally
open (NO) as indicated by the diagram in Fig.2. Its function is to
override the pressure switch when the gate reaches the end of its path,
and is exercising force on its frame. Its proper placement is essential
to prevent the gate from reversing the manoeuvre. This will be how
the motor will communicate to the control panel that it can increase
the pressure because it has reached the end of its path and it is not an
obstacle that must be released.
In order to be able to do without a limit switch when opening, it is
necessary for the panel to have the option that when the gate is opening
nds an obstacle, reverses the manoeuvre for one or two seconds so as
to release the obstacle and stop. If the panel does not have this option we
will need to place another limit switch (NO) in parallel when opening.
In this system, it is essential for the control panel to have an inhibition of
the pressure switch during the start of the closing manoeuvre. At start-
up, the motor requires an increase in force and this option allows an
increase in pressure avoiding an unwanted investment.
PHOTOCELL CONNECTION
When the control panel does not have an exclusive inlet for the photocell
we can connect it in series with the pressure switches. (Fig.3)
REGULATION
To increase sensitivity, turn it counter-clockwise, and to decrease
sensitivity, turn it clockwise. Turning will be done in 15-degree turns.
