The TEHA motorization system can operate a gate with one or two leaves, up to a maximum length of 1.75 m, in the case of light, openwork gates. In the case of a semi-open, heavy gate, the size of the leaf should be smaller.

The leaves can be asymmetrical (of different sizes) as long as the largest leaf does not exceed the size limit supported by the operator.

It is not recommended to install this motorization on a solid gate.

The gate must be fitted with a reinforcement point to which the operator can be attached.

The gate must be stable and balanced (it must not open or close by itself without external action).

The gate must open and close smoothly.

The gate must open towards the interior of the property on both sides.

Its maximum opening angle must not be less than 60°.

The pillar must be large enough to correctly accommodate the actuator bracket.

The pillar must not be rounded on the side receiving the actuator bracket.

The distance B materialized will depend on distance D (see Table Step 1 Measurements on the pillar).

The image shows the minimum and maximum distances at which the bracket can be fixed (with D=0 cm and D=15 cm).

The pillar must be clean and dry, and free of any fixings from an old motorization model.

It is imperative to maintain a safe lateral clearance between the open gate and any fixed part of the environment.

The floor must be straight and even. The gate must not rub against the ground.

The drive unit is not compatible with sloping entrances, either upwards or downwards.

The installation of FIXED and PERMANENT floor stops is MANDATORY for opening and closing.

The installation depth of the gate in relation to the inner face of the pillar is important. We call it distance D.

This cannot be less than 0 cm (negative distance) and cannot exceed 15 cm.

This distance determines the distance B at which the bracket is installed on the pillar (see pillar requirements).

If you have the option of adjusting the installation depth of the gate, take care to choose a location that allows you to have a distance B compatible with the width of your pillar.

If distance D is negative or greater than 15 cm, you will need to modify your abutment.

In the closed position, the gate must be parallel to the rear face of the pillar on which the pillar bracket will be installed.

It is strictly forbidden to install the cylinders on the outside of the gate (street side).

It is strictly forbidden to install the motors at a height of more than 1.50 m.

It is strictly forbidden to install the electronic box on a moving part of the gate.

It is not possible to install the pillar bracket on a perimeter wall perpendicular to the gate.

It is not possible to install the pillar bracket on the same side as the gate hinges.

It is not possible to install the jack on an unreinforced part of the gate.

If the size of your pillars does not allow you to respect distance B, it will not be possible to install the motorization.

A motorized gate system must be installed according to well-defined installation distances, to ensure optimal and safe operation.
If the motors are not installed according to the data in the table below, your motorized system may:
– fail to drive the leaves correctly (small opening angle, obstacle detection by the board, erratic operation, etc.).),
– failure to keep the leaves closed,
– destruction of one or more of the motor’s components
– failure to comply with the values defined in standard NF-EN 12453, resulting in serious damage to property or personal injury.

Any non-compliant installation resulting in malfunction, destruction or premature wear of the device will not be covered by the warranty.
Avidsen will not provide technical assistance until the motorization has been installed in compliance.

Measure the distance D (see Pre-requisites for installing the gate on the pillar).

Refer to the table for distance B (distance between the center of the mounting bracket and the hinges) (See Pillar requirements).

Assemble the two brackets. The cylinder’s mounting point on these brackets must be 31 mm above the middle of the gate’s reinforcement point.

Make sure the bracket is level and mark the holes to be drilled.

Mark the location of the holes in the pillar, ensuring that the pillar bracket is fitted horizontally at the end. Use 10 mm lag bolts or any other fastening system suited to the pillar material.

Please note that the stresses on the mounting bracket will be considerable when the motorization is running. We recommend embedding threaded rods at least 15 cm long. If the pillar is made of metal, we recommend that the threaded rods be welded or passed through and secured with self-locking nuts.
Consult a professional in case of doubt.

1) Position the cylinder’s rear fork on the bracket, positioning the washers above and below the bracket

2) Insert the stud

3) Lock with the pin

Turn the cylinder over and ensure that the carriage rod is approximately 5 mm from the cylinder’s internal end-of-travel position. If not, use a 9V LR61 battery to move the carriage. Alternatively, connect the motors to the electronic board (see chapter connection) and start the manual mode to power the motors while you adjust the carriage position.
Please note! It is very important to follow this step, otherwise the gate may not open properly. or may not close properly!

1. Close the gate by pressing it firmly against its central stop, then rotate the jack to place the base of the gate bracket on the gate. Assemble the gate bracket under the jack with the “butterfly screw” (4ᵉ hole).
2. Lay the bracket flat on the gate and note the position of the fixing holes.
3. Retain only the bracket and secure it to the gate using the appropriate fasteners. The forces applied to the gate leg during operation are considerable. To prevent the gate leg from being torn off, use suitable fasteners
   (rivets/threaded inserts or through-bolts).
4. Re-attach the cylinder to the bracket with the butterfly screw (4ᵉ hole).

Carry out the same operation for the second cylinder
