Table1 TECHNICALSPECIFICATIONSOFGEARMOTOR
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
Tp = pause time
Ti = interval time between one complete cycle and
the next

connection.
DESCRIPTION
The 844R 3Ph automation is ideal for controlling industrial vehicle
access areas.
The 844R 3Ph automation for sliding gates is an
electromechanical operator which transmits movement to the
sliding leaf via a pinion with rack or chain appropriately coupled
to the gate.
Operation of the sliding gate is controlled by electronic control
equipment housed in a container separated from the operator
(844 T).
When, with the gate closed, the control equipment receives an
opening command by remote control or from another suitable
device, it activates the motor until the opening position is
reached.
If automatic operating mode was set, the gate closes
automatically after the selected pause time has elapsed.
If semiautomatic operating mode was set, a second pulse must
be sent to allow the leaves to close again.
An opening pulse during re-closing, always causes movement
to reverse.
A stop pulse (if supplied) always stops movement.
For details on sliding gate behaviour in different function logics,
consult the installation technician.
Automations include safety devices (photocells, sensitive edges)
that prevent the gate from closing when there is an obstacle in
the area they protect.
The system ensures mechanical locking when the motor is not
operating and, therefore, installing any lock is unnecessary.
Manual opening is, therefore, only possible by using the release
system.
The gearmotor has an adjustable mechanical clutch providing
the necessary anti-crushing protection.
An inductive sensor detects transit of metal plates secured on
the rack, which correspond to the travel limit positions. The
USER’SGUIDE
