USAGE FREQUENCY
The curve allows the calculation of the maximum working time (T) based on the utilisation factor (F).
To ensure proper operation it is necessary to be located inside the work area, shaded in grey.
The tests have been carried out at an ambient temperature of 22 °C; if the motor is at a higher ambient temperature or is
exposed to direct solar radiation, the utilisation factor may be reduced by up to 20%.

Note. To ensure the full closing and opening of the gate, it is necessary to increase the manoeuvring times by 5 sec-
onds.
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 25 seconds?

CONCLUSION: when we transfer the data obtained to the
graph 1, the maximum usage period for the model 240 is 2h
and 15 min and for model 360 it is 1h and 30 min.
Whenever the dimensions of the gate and the dimensions of
assembly allow, it is advisable to use model 240.

SPECIAL DIMENSIONS OPENING INWARDS (Fig. 2, page 5)
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 gate mechanism models (240-360) 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 remain constant in both motors, model 360 C=90 mm and model 240 C=70 mm.
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 assembly dimensions 360 with thick discontinuous line,
special dimension).
Conclusion: We cannot choose model 240 because it goes beyond the positioning limits. The 360 mm stroke length motor allows higher
dimensions than the standard.

1. Place the pillar support (Fig. 1, page 7) by trimming or supplementing the support according to A and B dimen-
sions 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.
Proceed by extending the rod electrically until the end of its
stroke.

3. Trim or supplement the gate support according to dimension C of the table on page 5. Position the motor wit
the front support, with the rod fully extended (Fig. 2, page 7) and the ball joint threaded to the maximum (Fig. 3,
page 7). With the gate closed balance the motor and with the help of a spirit level (Fig. 4, page 7) mark the posi-
tion 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, page 7).
5. Manually operate the gate and open it about 10° less than the desired position, move the ring at the end of the
stroke on the rod (Fig. 9, page 7) to the telescopic bushing (Fig. 10, page 7) and attach 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. 11, page 7). 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 and opening stop (Fig. 12, page 7). This valve is common to control the speed of
the device before completing the closing and opening 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 (Fig. 13, page 7), the gasket (Fig. 14, page 7) and the case cover (Fig. 15, page 7) will be
press-tted.
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.

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.
BAC AND WINDPROOF SYSTEM
View of the motor from below.
By manipulating the red and blue valve (located in the lower
part), we can select in which manoeuvre we want the gate to be
manually reversible.
The options are:

LOCKING OPERATION
The BAC system incorporated in the HLR device oers a wide variety of possibilities. Here is how it should
be manipulated to get the most out of its performance.
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!

PRESSURE SWITCH CONNECTION.
To access the connection and regulation of the pressure switch remove the
screws located at the rear holding the pressure switch and pull it down as
indicated by the arrow (Fig. 1).
The pressure switch is a normally closed contact (NC), which opens when
the pressure regulated by the adjustment screw is exceeded (Fig. 2, No. 1).
The system consists of two pressure switches (Fig. 2), which are responsi-
ble for controlling the circuit pressure of both manoeuvres independently
when opening and closing. These are connected in series (Fig .3-Fig. 4). The
connection of the pressure switch signal to the control panel is made through
the two-joint strip (Fig.2, 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.3. 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 and 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 (N.A) 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 reversal.
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. 4).
REGULATION
To increase sensitivity, turn it counter-clockwise, and to decrease sensitivity,
turn it clockwise. Turning will be done in 15-degree turns.
Handling the pressure switch according to the type of opening:
-When the door opens inwards (page 5, Fig. 2):
Opening adjustment, Fig. 1 pressure switch A (under the blue limiter)
Closing adjustment, Fig. 1 pressure switch B (under the red limiter)
-When the door opens outwards (page 5, Fig. 2):
Opening adjustment, Fig. 1 pressure switch B (under the red limiter)
Closing adjustment, Fig. 1 pressure switch A (under the blue limiter)
IMPORTANT! It must be handled in accordance with current standard UNE-
EN 12453.
