Table 1 TECHNICAL SPECIFICATIONS OF GEARMOTOR
These instructions apply to the following model:
844R 3Ph
The FAAC mod. 844R 3Ph automation for sliding gates is an
electromechanical operator powered by three-phase voltage,
transmitting motion to the sliding leaf via a rack and pinion
drive suitably coupled to the gate.
The irreversible system ensures the gate is mechanically locked
when the motor is not operating and, therefore, no lock need to
be installed.
The gearmotor is supplied with an adjustable mechanical clutch,
providing the necessary anti-crushing protection.
A convenient manual release makes it possible to move the
gate in the event of a power-cut or fault.
The 844 INTERFACE board is fitted on board the operator. This
board is used for connecting the motor and the limit inductive
sensor to the 844 T electronic control unit, which must be housed
in a separate enclosure.
The 844R 3Ph automation is designed and manufactured to
control access of vehicles. Avoid any other use whatever.
1. DESCRIPTION AND TECHNICAL SPECIFICATIONS
1.1. MAXIMUM USE CURVE
The curve enables you to find maximum work time (T) according
to use frequency (F).
The 844R 3Ph gearmotor can operate continuously at 60% use
frequency.
To ensure efficient operation, you have to work in the work range
under the curve.
Important: The curve is obtained at a temperature of 24°C.
Exposure to the sun’s rays can reduce use frequency down to
20%.
Calculation of use frequency
This is the percentage of effective work time (opening + closing)
compared to total cycle time (opening + closing + pause time).
Calculation formula:
Ta + Tc
%F = X 100
Ta + Tc + Tp + Ti
where:
Ta = opening time
Tc = closing time
T p = pause time
Ti = interval time between one complete cycle and
the next

4. INSTALLATION OF AUTOMATION
4.1. PRELIMINARY CHECKS
To ensure safety and an efficient automation, make sure the
following requirements are met:
• The gate structure must be suitable for automation. In
particular, wheel diameter must be in proportion to the weight
of the gate to be automated, an upper guide must be
supplied, and travel limit mechanical stops must be fitted to
prevent the gate from derailing.
• The characteristics of the soil must ensure sufficient stability of
the foundation plinth.
• There must be no pipes or electrical cables in the plinth
excavation area.
• If the gearmotor is exposed to passing vehicles, if possible, fit
adequate guards to protect against accidental impact.
• Check if an efficient earth plate is present for connection to
the gearmotor.
4.2. FOUNDATION PLATE MASONRY
1) Assemble the foundation plate as shown in Fig.4.
2) The foundation plate must be positioned as in Fig. 5 (right-
hand closure) or Fig. 6 (left-hand closure) to ensure the rack
and pinion mesh correctly.
3) Prepare a foundation plinth as in Fig.7 and enclose the
foundation plate in a wall providing one or more sheaths for
routing electric cables. Using a spirit level, check if the plate
is perfectly level. Allow the cement to set.
4) Lay the electrical cables for connection to the accessories
and power supply as in Fig.3.
To facilitate making connections, allow the cables to
protrude by about 40 cm from the hole (Fig.5-6 ref. 쐃) of the
foundation plate.
