Answer:
The barrier uses a continuous hydraulic drive system equipped with positive hydraulic locks in both the open and closed positions, paired with patented electronic deceleration. Control is handled by the on-board FAAC 624 BLD microprocessor unit, which includes an integrated dual-channel loop detector.
The FAAC 620 Standard utilizes an industrial hydraulic drive assembly rather than electromechanical gearing. The internal mechanism comprises a hydraulic pump unit, double-acting plunger pistons, an equaliser, a transmission shaft, and an internal compression balancing spring lubricated with dedicated FAAC HP hydraulic oil.
Key engineering features include:
- Integrated Hydraulic Locking: Provides positive mechanical holding in both the fully opened and fully closed positions, preventing manual forcing without requiring separate external lock accessories.
- Patented Electronic Deceleration: Automatically slows beam speed near limit stops to minimize mechanical vibration and prolong actuator service life.
- On-Board 624 BLD Control Board: Features a 3-button programming interface (+, -, F) supporting 11 distinct operational logics, including Automatic, Semi-automatic, and dedicated Parking (P) modes.
- Integrated Vehicle Detection: Incorporates a built-in dual-channel inductive loop detector directly on the controller board.
- Enclosure Construction: Load-bearing steel cabinet protected with a cataphoresis anti-corrosion bath treatment and finished in RAL 2004 orange polyester powder coating, featuring an external triangular key override for manual release during power loss.
