The Combi 740 is an oil-hydraulic automated operator designed for opening and closing swinging gates, installed below ground at the base of the gate's rotation hinges. It is a self-contained unit with a built-in hydraulic drive, entirely housed within an enclosure cemented at the gate leaf's base. An external electronic programmer controls all movement functions, either automatically or semi-automatically, based on user requirements. The gate opener includes various accessories to ensure necessary safety and maneuverability, making it suitable for both public and private installations.
The Combi 740 is available in different versions, offering flexibility in leaf rotation and locking mechanisms. The 110° version is designed for a maximum leaf rotation of 110°, while the 175° version allows for a maximum rotation of 175°. Both versions come in "Normal" and "Locking" configurations. The "Normal" version, whether 110° or 175°, is non-locking in both movement directions, making an electric lock always recommended for secure operation. The "Locking" version, also available for both 110° and 175° rotations, provides locking in both movement directions, and is particularly recommended for leaves up to 2.0 meters long without an electric lock. For leaves longer than 2.0 meters, an electric lock is always necessary, even with the locking version.
Additionally, the Combi 740 offers specialized features such as a "Brake" version and a "Flow Regulator" version. The "Brake" version, available for both 110° and 175° rotations, includes adjustable hydraulic braking during the last 40 cm of movement, allowing for a controlled slowdown. The "Flow Regulator" version, also for both 110° and 175° rotations, allows for adjustment of the hydraulic flow, which controls the leaf speed, and is particularly recommended for leaves longer than 2.5 meters.
Installation of the Combi 740 involves cementing the enclosure to the gate's base, requiring the removal of the lower leaf hinge as the operator's rotation shaft acts as the new lower hinge. For installations with two leaves, precise alignment of the two enclosures is crucial, achieved by pulling a string through designated holes. Before securing the enclosure with concrete, its inner hole must be aligned with the upper hinge, and the enclosure must be perfectly level, with its upper edge flush with the finished ground level. The gate leaf can be installed even without the Combi 740 initially, as the enclosure is pre-set to receive a gate spacer hinge that replaces the lower hinge.
The connection between the gate leaf and the Combi 740 operator can be established in three ways: with an emergency manual release system, a simple support plate with a square hole ferrule, or just a square hole ferrule. In all cases, these components must be tightly welded to the leaf base, aligned with the upper hinge. For the single square hole ferrule, it's important to weld it to the leaf with the Combi 740 shaft rotated by 5° or 10° before it reaches the end of its travel, a process referred to as "putting into phase." The Right and Left Combi 740 operators are installed on the respective sides of the gate, as viewed from inside the property, with the distinction indicated by a stamp on the base of the square rotation shaft. Before making electrical connections, the leaf opening and closing stops must be secured to the ground, with the opening leaf stop placed approximately 5° before the rotation shaft's end of travel.
The emergency manual release system differs between the 110° and 175° versions. For the 110° Combi 740, the RIGHT operator is paired with the RIGHT (Dx) emergency manual release, and the LEFT operator with the LEFT. For the 175° Combi 740, the RIGHT operator is paired with the LEFT (Sx) emergency manual release, and the LEFT operator with the RIGHT. The Combi 740 is secured within its enclosure using two hexagonal studs and two raised slits at the base. Before any operation, including manual, the closing and opening gate stops must be installed. Initial opening maneuvers can be performed by "releasing" the Combi 740 from the leaf, either using the release key (if an emergency manual release is installed) or by turning the hydraulic jack's release lever. It is crucial that this lever is always closed during normal Combi 740 operation.
Electrical connections and wiring must comply with installation standards and current laws, including the Machinery Directive 2006/42/CE. This requires qualified technical personnel to perform a complete risk analysis and adopt appropriate safety measures. The Elpro 13 exp programmer, which controls the system, should be installed in a dry, protected area, preferably within its own container. For additional components, a cabinet certified for outdoor use is recommended. The programmer is powered by 1 mm² diameter electrical cables for distances up to 50 meters; for longer distances, cables with appropriate diameter wires should be used. For external accessories, 1 mm² or 0.5 mm² diameter wires can be used.
Adjustments for the Combi 740 include thrust force, brake, and leaf speed. Anti-crushing safety is ensured by maximum hydraulic pressure valves, which allow for precise and stable thrust force adjustment. These valves are protected by a casing, and adjustments are made by loosening screws with an Allen wrench. The red adjusting screw increases thrust force during closing when tightened and decreases it when loosened. The green adjusting screw increases thrust force during opening when tightened and decreases it when loosened. The brake adjustment allows for controlling the slowdown during the last few degrees of leaf rotation (approximately 40 cm). The leaf speed regulator, available for models with flow regulators, allows for adjusting leaf speed in both opening and closing directions, particularly recommended for leaves longer than 2.50 meters.
Maintenance of the Combi 740 requires regular checks and interventions to ensure optimal performance and safety. A qualified installer must perform these checks, following the instructions in the "Maintenance Booklet." Hydraulic oil levels should be checked at least every six months, and electrical and safety systems at least once a month. Any extraordinary maintenance or repairs must be carried out by the company that performed the installation. It is strictly forbidden to dispose of harmful materials in normal waste receptacles; they must be removed and disposed of by specialized companies. Before any maintenance or repair, the electrical supply must be disconnected by removing the fuses from the junction box. Fadini's development process emphasizes continuous improvement, ensuring that products comply with European standards.
