FAAC 844 R 3 PH Electrical, Mechanical, and Peripheral Compatibility

The FAAC 844 R 3 PH electro-mechanical gearmotor (ERP Ref: KTI02006002844P) is engineered as an industrial-grade drive unit designed to automate commercial and industrial sliding gates. Proper field installation requires precise mechanical matching of drive pinions, designated three-phase electrical connections, and coordinated integration with external control boards, inductive limit sensors, and peripheral safety devices.

Control Board & Electrical Power System Compatibility

The 844 R 3 PH motor does not incorporate an onboard control card. It is specifically designed to be operated via a remote installation of the dedicated FAAC 844 T three-phase microprocessor control board (control unit is not included with the gearmotor). Electrical and control compatibility parameters include:

Line Voltage: 400 Vac three-phase (+6% / -10%) at 50/60 Hz frequency.
Motor Load Management: The FAAC 844 T control board accommodates a maximum motor load of up to 1,300 W (1.3 kW), fully supporting the 950 W absorbed power and 2.5 A absorbed current of the 844 R 3 PH electric motor.
Integrated Power Contactors & Braking: The 844 T panel incorporates dedicated industrial power contactors and an integrated electronic braking device to arrest inertia on high-mass gate panels.
Auxiliary Power Output: The 844 T controller supplies a 24 Vdc accessory output rated up to a maximum of 500 mA to power external access control and optical safety hardware.

Drive Pinion and Gate Mass Configurations

Mechanical rack interface compatibility depends directly on the selection of the output drive pinion. The unit supports both Z12 and Z16 tooth pinion profiles, which determine maximum permissible gate mass and operational travel speed:

Pinion Type	Maximum Gate Weight	Linear Gate Speed	Reduction Ratio
Z12 Pinion	2,200 kg	7.2 m/min	1:30 (1,400 rpm motor)
Z16 Pinion	1,600 kg	9.5 m/min	1:30 (1,400 rpm motor)

Both pinion configurations utilize the internal 1:30 reduction gearbox and twin-disk anti-crushing clutch running in an oil bath of FAAC OIL XD 220. Torque output is mechanically adjustable from 0 to 62 Nm via a hexagonal key directly on the clutch assembly to meet gate mechanical load requirements.

Peripheral Safety and Access Control Compatibility

The system architecture supports direct terminal interfacing through the FAAC 844 T controller and junction box layout for the following FAAC hardware:

End-of-Stroke Sensing: Inductive limit-switch assembly with dedicated target plates mounted on the gate rack.
Active Safety Detection: FAAC FOTOSWITCH safety photocells and CN 60 E mechanical or resistive safety edges.
Visual Signalling: FAACLIGHT industrial flashing indicator lamp.
Access Triggering: FAAC T10 key selector switch and FAAC PLUS 1 433 radio receiver card.

Foundation and Physical Interface

The gearmotor has an external footprint of 275 mm (L) x 191 mm (W) x 397 mm (H) and an overall operating weight of 15 kg with oil. For civil installation, the operator is compatible with an optional galvanised steel foundation plate engineered with integrated side and height adjustments. Because the internal mechanical design is non-reversing, it holds the gate securely closed upon motor stop, eliminating the requirement for electric locking hardware. In power outages, manual gate transit is enabled using the integrated lever-operated release mechanism fitted with a coded key.

FAAC 844 R 3 PH Industrial Sliding Gate Operator Installation & Commissioning Guide

Mechanical Foundation & Operator Mounting

The FAAC 844 R 3 PH gearmotor (ref. KTI02006002844P) requires a stable, rigid concrete foundation capable of handling the high dynamic loads exerted by heavy industrial sliding gates weighing up to 2,200 kg. Mechanical anchoring is executed using an optional galvanised steel foundation plate. This plate incorporates integrated height and lateral adjustment channels, allowing installers to level the operator precisely relative to the gate travel line and rack pitch.

The physical footprint of the unit measures 275 mm (length) by 191 mm (width) by 397 mm (height), with an assembled weight of 15 kg including factory-filled FAAC OIL XD 220 lubrication oil. The lower and upper half-body housings are manufactured from high-resistance pressure-cast aluminium treated with a protective cataphoresis finish, topped by a rugged ABS enclosure cover that shields the drive mechanism from environmental exposure within its IP 44 ingress rating.

Drive Pinion Selection & Rack Engagement

The mechanical transmission must be configured according to site velocity and gate mass requirements using standard module gear racks and compatible drive pinions:

Z12 Pinion Configuration: Engineered for maximum load capacities up to 2,200 kg. Delivers a linear gate transit speed of 7.2 m/min.
Z16 Pinion Configuration: Engineered for intermediate loads up to 1,600 kg. Increases transit velocity to 9.5 m/min.

During mechanical installation, verify proper meshing clearance between the pinion and the gate rack along the entire stroke length. Avoid resting the total gate weight onto the motor drive shaft; maintain a minimal uniform operational clearance between the tooth tip and the rack root to avoid mechanical strain on the 1:30 internal reduction screw gearing.

Inductive Limit-Switch & Stroke Calibration

Travel limit sensing relies on a contactless inductive limit-switch assembly actuated by dedicated metal target plates mounted directly at the opposing extremities of the gate rack. Mount the plates so they pass within the detection field of the inductive sensor as the leaf reaches full open and full closed positions. Contactless inductive operation eliminates mechanical fatigue, wear, and winter freeze-up failures across its operational temperature spectrum of -20°C to +55°C.

Torque Adjustment & Mechanical Clutch Setup

The operator features an integrated twin-disk anti-crushing clutch running completely immersed in an oil bath. Drive torque is continuously adjustable between 0 Nm and 62 Nm to comply with anti-crushing safety standards:

Access the internal clutch calibration screw beneath the ABS cover.
Adjust the mechanical transmission threshold directly using a standard hexagonal key.
Tighten to increase pushing force up to the 62 Nm ceiling; loosen to reduce transmitted linear force according to gate inertia.
Verify that the continuous oil-bath immersion remains topped with genuine FAAC OIL XD 220 for sustained thermal dissipation across intensive 70% duty cycle duty regimes (up to 70 cycles/hour).

Power Supply & Electrical Control Integration

The FAAC 844 R 3 PH electric motor absorbs 950 W with an operational draw of 2.5 A and requires a balanced 400 Vac three-phase power supply (+6% / -10%) at 50/60 Hz. The motor operates at 1,400 rpm.

The base operator does not house an integrated control board and must be wired to an external FAAC 844 T microprocessor-based three-phase control board. When wiring the system:

Main Motor Feed: Route three-phase wiring through power contactors capable of handling inductive loads up to 1.3 kW.
Electronic Braking: Ensure the 844 T electronic brake circuit is configured to overcome gate momentum on deceleration.
Accessory Power: Power peripheral safety devices via the 24 Vdc accessory output (rated up to 500 mA maximum).
Safety & Control Circuitry: Interconnect required terminal nodes including FOTOSWITCH safety photocells, CN 60 E mechanical or resistive safety edges, FAACLIGHT flashing indicators, T10 key selectors, PLUS 1 433 radio receiver cards, and junction boxes as indicated on the standard system layout.

Manual Override Operation

Because the internal gear architecture is irreversibly non-reversing, the gate mechanically locks in place upon closure without the addition of electric locks. In the event of a three-phase power failure, access the release mechanism via the integrated lever-operated release device using the supplied coded key to manually disengage the gear train and move the leaf freely by hand.

Preventive Maintenance and Inspection Guidelines for FAAC 844 R 3 PH

Lubrication and Oil-Bath Fluid Management

The FAAC 844 R 3 PH gearmotor relies on complete, continuous oil-bath submersion to protect its internal mechanical components and twin-disk clutch from thermal and frictional wear. Scheduled preventive maintenance must include regular level checks of the FAAC OIL XD 220 fluid. Because the unit operates under heavy commercial and industrial duty profiles—supporting up to 70 cycles per hour (70% maximum use frequency)—maintaining proper oil volume is essential. The total weight of the gearmotor filled with oil is 15 kg. Any significant reduction in weight or visible loss of lubricant indicates an integrity issue that requires immediate inspection of the gaskets and the pressure-cast aluminium half-body joints.

During lubrication checks, verify that the FAAC OIL XD 220 fluid remains free of metal shavings, debris, or moisture ingress. If the fluid appears degraded or contaminated, drain the housing entirely and refill with genuine FAAC OIL XD 220 to ensure the internal reduction gearing (1:30 ratio) and drive components remain fully submersed. Ensure that the ABS outer cover and housing seals are reseated accurately to maintain the IP 44 environmental protection rating.

Twin-Disk Anti-Crushing Clutch Calibration

The operator features a mechanical twin-disk anti-crushing clutch operating in the oil bath, providing an adjustable torque output from 0 to 62 Nm. Periodic calibration of this clutch ensures continuous site safety and prevents premature motor strain. Calibration is carried out mechanically using a standard hexagonal key on the clutch adjustment mechanism.

Inspect the clutch settings quarterly or semi-annually depending on operational intensity. If gate movement exhibits slippage or if crushing force thresholds exceed facility specifications, adjust the hexagonal screw to re-establish the correct operational torque. Maintaining precise clutch calibration ensures that the 950 W motor does not draw current above its rated 2.5 A under standard transit conditions, especially when driving heavy structural gates up to 2,200 kg with a Z12 pinion or 1,600 kg with a Z16 pinion.

Limit Switch, Foundation, and Mechanical Drive Checks

Routine service protocols must verify the inductive limit-switch assembly and target plates:

Inductive Limit Switch: Inspect the sensing face and steel target plates for physical damage, clearance variance, or debris accumulation. Ensure the inductive switch reliably signals the dedicated FAAC 844 T control board at end-of-stroke travel limits.
Pinion and Rack Alignment: Inspect the Z12 (7.2 m/min gate speed) or Z16 (9.5 m/min gate speed) drive pinion teeth for uniform contact along the gate rack. Verify that the gate load rests entirely on its running track and does not exert downward vertical load onto the drive pinion.
Foundation Anchors: Check the optional galvanised steel foundation plate. Ensure the side and height adjustment hardware remains torqued to prevent vibration or gear misalignment.

Manual Release and Enclosure Servicing

Because the 844 R 3 PH is a non-reversing electro-mechanical screw gearmotor, it provides positive mechanical locking when stationary without supplemental electric locks. Routine checks must include testing the lever-operated manual release mechanism using the supplied coded key. Verify that the release lever disengages smoothly to allow manual gate transit during power loss, and relocks firmly upon closing the lever.

Clean the exterior ABS protective cover and the cataphoresis-treated aluminium lower and upper half-body housings. Inspect cable entries, gland seals, and three-phase 400 Vac (+6% -10%, 50/60 Hz) wiring terminations leading to the external FAAC 844 T microprocessor control panel. Confirm that temperature limits remain within the rated -20°C to +55°C operating envelope.

Industrial & Commercial Application Scenarios for FAAC 844 R 3 PH

The FAAC 844 R 3 PH electro-mechanical gearmotor (ref. KTI02006002844P) is engineered to automate heavy industrial and commercial sliding gates. Operating on a 400 Vac (+6% -10%, 50/60 Hz) three-phase industrial power supply, this drive unit provides the mechanical strength, thermal endurance, and duty rating required for continuous vehicle transit portals, secure manufacturing zones, and freight corridors.

Heavy Industrial Manufacturing and Production Plants

Heavy production facilities utilize massive steel structural gates to secure wide perimeter entrances against unauthorized vehicle entry. The FAAC 844 R 3 PH handles solid-leaf sliding structures weighing up to 2,200 kg when configured with a Z12 drive pinion. Internal mechanical transmission is driven by a 950 W three-phase electric motor (2.5 A absorbed current) operating through a 1:30 reduction ratio at 1,400 rpm motor shaft speed.

Because the internal screw assembly is strictly non-reversing, the gate locks mechanically against forced back-driving upon full closure, eliminating the need to specify or wire secondary electric locks. In continuous 24/7 operating environments, the housing’s pressure-cast aluminium construction with protective cataphoresis treatment and IP 44 ingress protection withstands ambient plant temperatures ranging from -20°C to +55°C.

High-Frequency Logistics Depots and Freight Hubs

Distribution centers, bonded warehouses, and multi-modal transport terminals demand automated gate hardware capable of supporting relentless entry cycles without thermal breakdown. The FAAC 844 R 3 PH provides an intensive 70% use frequency rating, supporting up to 70 duty cycles per hour.

Continuous operation at high cycle frequencies is sustained by full oil-bath lubrication utilizing FAAC OIL XD 220 fluid. All internal gears, bearings, and the mechanical twin-disk anti-crushing clutch remain submersed, eliminating localized frictional heat and component galling during rush-hour transport traffic. Drive force can be field-calibrated between 0 and 62 Nm via a hexagonal key directly on the oil-bath clutch to protect vehicles and cargo.

Application Configuration: Z12 vs. Z16 Drive Pinions

Engineers and gate fabricators configure the FAAC 844 R 3 PH across two distinct duty profiles depending on total gate mass and required transit velocity:

Configuration Parameter	Z12 Pinion Setup	Z16 Pinion Setup
Maximum Supported Leaf Weight	2,200 kg	1,600 kg
Gate Transit Speed	7.2 m/min	9.5 m/min
Target Applications	Heavy structural steel portals, industrial blast/security gates	Commercial fleet access, medium-weight high-traffic perimeter fences
Torque Control	0 to 62 Nm adjustable	0 to 62 Nm adjustable

Critical Infrastructure and Perimeter Control Checkpoints

Commercial utilities, data centers, and corporate perimeters integrate the FAAC 844 R 3 PH alongside the dedicated external FAAC 844 T microprocessor control board. The 844 T board delivers electronic motor braking to arrest heavy gate inertia smoothly at inductive limit switch target plates, avoiding mechanical slamming on end-stops.

Perimeter automation networks can route 24 Vdc (500 mA maximum) accessory power from the 844 T board to support peripheral detection hardware such as FOTOSWITCH safety photocells, CN 60 E safety edges, T10 key selector switches, and PLUS 1 433 radio receivers. During power disruptions, access is maintained via an integrated lever-operated manual release secured with a coded industrial key.
