The FAAC B680H hybrid automatic hydraulic boom barrier is engineered for intensive industrial operation, featuring a 100% continuous duty cycle and mechanical balancing springs tested to exceed 2,000,000 cycles without mechanical failure. To maintain peak operating efficiency across high-frequency commercial entries, toll plazas, and perimeter checkpoints, routine preventive maintenance should focus on hydraulic fluid management, mechanical balancing verification, structural casing inspection, and control board diagnostic checks.
Hydraulic Circuit and FAAC HP OIL Servicing
The barrier mechanism relies on a 36 Vdc brushless electric motor coupled to an internal hydraulic pump capable of delivering a maximum flow capacity of 3.2 l/min. The hydraulic circuit is charged with specialized FAAC HP OIL, formulated to maintain viscous stability and lubrication across the operational ambient temperature range of -15°C to +65°C.
During scheduled maintenance intervals, technicians must inspect the internal hydraulic drive system, piping unions, and cylinder assemblies for signs of fluid weeping or external contamination. If an optional anti-vandalism hydraulic bypass valve is installed, verify its mechanical seating to confirm that forced boom motion will not over-pressurize internal hydraulic seals. If an anti-panic group manual release mechanism is fitted, actuate the release to verify proper manual disengagement of the hydraulic circuit during simulated power loss events.
Structural Upright and Modular Housing Inspection
The FAAC B680H utilizes an 85 kg structural architecture partitioned into a 65 kg internal load-bearing upright post and an independent 20 kg outer housing manufactured from steel or stainless-steel. The load-bearing upright is factory-protected with a 100-micron epoxy zinc anti-corrosion primer treatment plus industrial paint.
A primary operational benefit during servicing is that the non load-bearing outer housing can be unbolted and lifted upward directly over the upright post without dismantling the barrier arm, pocket, or internal post. Service technicians can conduct thorough visual inspections of the internal upright, anchor bolts, and foundation plate interface (including retrofitted FAAC 620 or 640 foundation plates) without taking the primary barrier mechanism out of mechanical alignment.
Mechanical Balancing Springs and Boom Assembly
Continuous-use reliability depends on properly counterbalanced tension across the modular aluminum beam (spanning 2 m up to 8.3 m with internal module joints for clear roadway widths up to 8.0 m). Periodically verify the following mechanical assemblies:
- Spring Counterbalancing: Inspect the primary balancing springs to ensure tension remains balanced across full 90-degree travel without mechanical binding or spring fatigue.
- Beam Fixtures and Dampers: Inspect the mechanical arm pocket, beam mounting hardware, and the protective rubber bumper fitted along the bottom profile of the round or elliptical beam.
- Modular Joint Integrity: For multi-section arms joined to reach extended spans, check the internal invisible connection joint for rigidity and alignment.
E680 Control Board, Absolute Encoder, and Electrical Checks
The upper cabinet section houses an integrated DIN rail and a transparent protective enclosure containing the E680 microprocessor control unit. The unit operates from a 100 Vac to 240 Vac (50/60 Hz) switching power supply, drawing 240 W absorbed power and 1.1 A at 230 V. The overall cabinet enclosure provides IP56 ingress protection verified by TÜV Süd.
Verify that motor rotation speed operates within the calibrated 1,000 RPM to 6,000 RPM range, and inspect the integrated absolute encoder to confirm that automatic deceleration zones and obstacle-reversal safety profiles are operating within specified parameters. Check terminal blocks on the two integrated inductive loop detector circuits and verify plug-in GSM, Ethernet, or Wi-Fi communication modules. If the system utilizes the optional XBAT 24 emergency backup power kit, inspect the charging circuit and the Nickel-Metal Hydride cells (they are not included) or backup batteries (they are not included) for charge retention.
Preventive Maintenance Inspection Schedule
| Frequency | Component | Maintenance Action |
|---|---|---|
| Monthly | Barrier Boom & Rubber Bumper | Inspect round/elliptical beam straightness, rubber bumper integrity, and modular arm connection joint tightness. |
| Quarterly | Hydraulic System & FAAC HP OIL | Check pump seals, hose fittings, and fluid condition within the -15°C to +65°C operating circuit; test anti-panic manual release. |
| Bi-Annually | Balancing Springs & Pocket | Verify spring counterbalance tension across travel; inspect mechanical pocket hardware and pivoting breakout sensors if fitted. |
| Annually | E680 Electronics & Encoder | Verify deceleration curves via absolute encoder, test dual integrated loop detectors, inspect transparent DIN enclosure, and test backup batteries (they are not included). |
