These instructions apply to the following models:
844 R Reversible
The 844 R Reversible FAAC automated system for sliding gates is
an electro-mechanical operator which transmits movement to
the sliding leaf via a rack and pinion appropriately coupled to
the gate.
The reversible system enables the gate to be moved manually
when the motor is not operating. Consequently, an electric lock
must be installed to ensure locking during closure.
The gearmotor is equipped with an adjustable mechanical
clutch which makes it possible to adjust the thrust force exerted
on the gate.
A handy manual release facility makes it possible to move the
gate in the event of mechanical problems with the gearmotor.
The electronic control unit can be housed inside the operator
(462DF) together with the installation kit, or in a separate
enclosure (578D or 462DF) - see chapter 5.
The 844 Reversible automated system was designed and built
for controlling vehicle access. Do not use for any other purpose.

1.1. MAXIMUM USE CURVE
The curve makes it possible to establish maximum work time (T)
according to use frequency (F).
E.g.: The 844R Rev. gearmotor can operate non-stop at a use
frequency of 70%.
To ensure efficiency operation, operate in the work range under
the curve.
Important: The curve is obtained at a temperature of 24°C.
Exposure to the direct sun rays can reduce use frequency down
to 50%.
Calculation of use frequency
The percentage of effective work time (opening + closing)
compared to total time of cycle (opening + closing + pause
times).

4. INSTALLING THE AUTOMATED SYSTEM
4.1. PRELIMINARY CHECKS
To ensure safety and an efficiently operating automated system,
make sure the following conditions are observed:
• The structure of the gate must be suitable to be automated.
Fig. 2
Dimensions are in mm.
2. DIMENSIONS
Specifically: the wheel diameter must be in relation to the
weight of the gate to be automated; an upper guide must
be present; mechanical travel stops must be fitted to prevent
the gate derailing.
• The soil must permit sufficient stability for the foundation plinth.
• There must be no pipes or electric cables in the plinth
excavation area.
• If the gearmotor is exposed to passing vehicles, install, if
possible, adequate means of protection against accidental
impact.
• Check if an efficient earth socket is available for connecting
the gearmotor.
4.2. MASONRY FOR FOUNDATION PLATE
1) Assemble the foundation plate as in Fig.4.
2) The foundation plate must be located as shown in Fig. 5 (right
closing)orFig.6(leftclosing)toensurecorrectmeshingbetween
rack and pinion.
3) Make a foundation plinth as shown in Fig. 7 and wall the
foundation plate, providing one or more sheaths for routing
the electric cables. Using a spirit level, check if the plate is
perfectly level. Wait for the cement to set.
4) Lay the electric cables for connection to the accessories and
the electric power supply as shown in Fig. 3 or 3A:
To facilitate making the connections, make the cables come
out by about 40 cm from the foundation plate hole (Fig.5-6
ref.쐃).

4.3. MECHANICAL INSTALLATION
1) Assemble, on the operator, the securing corners and the anti-
vibration spacers as shown in Fig. 8.
2) Open the cover, unscrewing the securing screws.
3) Fit the operator on the plate, using the supplied washers and
nuts as shown in Fig. 9.
During this operation, route the cables through the raceway
on the operator's lower half-body (Fig. 10 ref. A). Take great
care in unsheathing all the cables so that the cable gland
grips only the individual wires (Fig.10 ref. B).
To access the unit, refer to chapter 5.
4) Adjust the height of the feet and the distance from the gate
- refer to Fig. 11.
5) Secure the gearmotor on the foundation plate, tightening
the nuts as shown in Fig.12.

8.
4.4. INSTALLING THE RACK
4.4.1. STEEL RACK TO BE WELDED (Fig. 13)
1) Fit the three threaded pawls on the
rack element, positioning them on
the upper part of the slot. In this way
the play on the slot will enable any
adjustments long-term.
2) Manually move the leaf to its closed
position.
3) Lay the first piece of rack level on the
pinion and weld the threaded pawl on the gate as shown
in Fig. 14.
4) Manually move the gate, checking if the rack is resting on the
pinion and weld the second and third pawls.
5) Fit another rack element next to the previous one, using a
piece of rack, as shown in Fig. 15, to synchronise the teeth of
the two elements.
6) Move the gate manually and weld the three threaded
pawls. Carry on like this until you have fully covered the gate.

4.5. INSTALLING THE ELECTRIC LOCK
As the gearmotor allows the gate to be moved manually when
the motor is not operating, an electric lock must be installed to
ensure locking during closure.
The lock must be installed vertically on the upper guide upright,
if gate height permits, so that release is possible both from inside
and outside (fig. 18).

Notes on installing the rack
• Make sure that, during gate travel, all the rack elements
do not come out of the pinion.
• Do not, on any account, weld the rack elements either
to the spacers or to each other.
• After you have finished installing the rack, to ensure
correct meshing with the pinion, we advise you to lower the
position of the gearmotor by about 1.5
mm (Fig. 17).
• Manually check if the gate
correctly reaches the mechanical travel
stops and if there is any friction during
travel.
• Do not use grease or other
lubricants between rack and pinion.
4.4.2. STEEL RACK TO BE SCREWED (Fig. 16)
1) Manually move the leaf to its closed position.
2) Lay the first piece of rack level
on the pinion. Then place the spacer
between rack and gate, positioning
it on the upper part of the slot.
3) Mark the drilling point on the
gate. Drill Ø 6.5 mm and thread with
a Ø 8 mm tap. Screw the bolt.
4) Manually move the gate,
checking if the rack is resting on the
pinion and repeat the operations in
point 3.
5) Fit another rack element next
to the previous one, using a piece of rack, as shown in Fig. 16, to
synchronise the teeth of the two elements.
6) Manually move the gate and perform the securing
operations as for the first element, carrying on like this until you
have fully covered the gate.

6. START-UP
6.1. ELECTRIC CONNECTIONS
Make all the electric connections on the board as shown in
chapter 5, including earthing the operator (Fig. 24).
The 844 operator is equipped with a limit sensor (MLS) which
detects the transit of the two magnets fitted on the side of the
rack facing the operator (fig. 25).
Procedure for correct positioning of the two supplied magnets:
1) Check if the operator is in manual mode (see chapter 8).
2) Manually take the gate to opening position, leaving 2 -
5 cm from the mechanical travel stop.
3) Fit the magnet (without removing the protective film from
the adhesive side) on the face of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in opening direction until the limit sensor is
activated, checking this on the unit. Then take the
magnet forward another 45mm.
4) Manually take the gate to closing position, leaving 2 - 5
cm from the mechanical travel stop.
5) Fit the magnet (without removing the protective film from
the adhesive side) on the face of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in closing direction until the limit sensor is activated,
checking this on the unit. Then take the magnet forward
about another 45mm.
6) Take the gate to its halfway travel point and relock the
system (see chapter 9).
7) Fix the required deceleration values, consulting the unit’s
instructions and run the automated system for at least one
complete cycle.
8) Check if the gate stops at about 2-5 cm from the
mechanical travel stop. If necessary, correct the position
of the magnets and check if the stop point is correct.
9) Mark the position of the magnets on the rack, and remove
them.
10) Clean the rack on its fitting points, remove the film on the
adhesive parts of the magnets (fig.25 ref. 1) and re-
position the magnets with the adhesive strip in contact
with the rack (fig.25 ref. 2).
11) The distance between the limit sensor and the magnets
must be from 5 to 12 mm.
6.2. ADJUSTMENT OF MLS LIMIT SENSOR
Fig. 25
12) The magnets must be fitted on the rack but never on the
securing screws. If necessary, fit the magnet in contact
with the screw and adjust the decelerations to obtain the
correct stop point, as shown in the instruction for the unit.
Attention: due to their powerful magnetic field, the supplied
magnets can damage magnetic band components (credit cards,
magnetic tapes, floppy disks, etc) and electronic and mechanical
equipment (e.g. watches, LCD screens). We advise you not to
bring them near to objects that could be damaged if 'immersed'
in a magnetic field.
Fig. 24

17
6.6. ADJUSTING THE MECHANICAL CLUTCH
The 844R Rev operator is equipped with a mechanical clutch.
Procedure for adjusting the action threshold of the mechanical
clutch (we advise you to set it in compliance with current
standards):
1) Cut power to the automated system.
2) Keep the motor shaft locked with a wrench, and turn the
clutch adjustment screw with an Allen wrench or screwdriver
Fig. 26.
To increase torque, turn the screw clockwise.
ÂThe operator is supplied with clutch set to maximum value.
Therefore, you should initially turn the screw counter-
clockwise to reach optimum setting.
To reduce torque, turn the screw counter-clockwise.
3) Power up the automated system and check if the torque
you have just carried out is correctly set.
6.7. CHECK OF STOP POINTS
Take care over the setting of the post-travel-limit deceleration
and braking: if deceleration is too long or braking is insufficient,
the marker fitted on the gate’s rack (magnet) can overtake
the sensor until the latter is disengaged. When the gate stops,
make sure that only the limit sensor in question is engaged. If the
sensor is engaged and then disengaged, or both the limit sensors
are engaged, check the decelerations again as indicated in
the instruction of the unit.
6.8. CHECK OF SAFETY DEVICES AND ACCESSORIES
Check correct operation of the following: all safety and anti-
crushing devices and the accessories used in the system.
7. FINAL OPERATIONS
After completing installation, remove the breather screw (see
fig. 27) and apply the danger signal tape on the top of the
cover (Fig. 28).
Fit the side panels by pressure, and secure the cover with the
supplied screws.
Hand the “User’s Guide” to the Client, explain correct operation
and use of the gearmotor, and indicate the potentially
dangerous areas of the automated system.
Fig. 26
Fig. 27
Fig. 28

18
8. MANUAL OPERATION
If the gate has to be moved manually, due to a power-cut, it is
sufficient to push or pull it, because the reversible motor enables
the gate to be moved manually.
Also make sure that the electric lock is not ON.
If the gate has to be moved manually due to a fault or
malfunction of the automated system, use the release device
as follows:
1) Open the electric lock with the key, checking if the gate is
free to move.
2) Open the protective door and fit the supplied key in the
lock (Fig. 29).
3) Turn the key clockwise and pull the release lever as shown in
Fig. 30.
4) Open and close the gate manually.
10. ASSEMBLY OF THE CN 60E CONTROL UNIT
(OPTIONAL)
The operator is designed to house - with the aid of a DIN bar -
the control unit of the CN 60E conductive safety edge. Cut the
DIN bar to measure and secure it to the operator with two screws
in the two appropriate holes, and hook on the CN 60E control
unit (Fig.31).
9. RESTORING NORMAL OPERATION MODE
To prevent an involuntary pulse from activating the gate during
the manoeuvre, cut power to the system before re-locking the
operator.
1) Re-close the release lever.
2) Turn the key counter-clockwise.
3) Remove the key and close the lock protection door.
4) Move the gate until the release device meshes.

11. SPECIAL APPLICATIONS
There are no special applications.
12. MAINTENANCE
Run a functional check of the system at least every 6 months,
with special attention to the efficiency of the safety devices
(Including the thrust force of the operator) and release devices.
Periodically check quantity of oil inside the operator.
An annual check is sufficient for low to medium use frequency;
for heavier duty, check every 6 months.
To access the tank, temporarily remove the oil filling plug (Fig.32).
Oil visual check: oil must touch the copper windings of the
electric motor.
To top up, pour in oil up to the level.
Use only FAAC XD 220 oil.

the system before restoring normal operation.
- Do not in any way modify the components of the automated
system.
- Do not attempt any kind of repair or direct action whatever
and contact qualified FAAC personnel only.
- At least every six months: arrange a check by qualified
personnel of the automated system, safety devices and earth
connection.
DESCRIPTION
The 844R Reversible automated system is ideal for controlling
vehicle access areas of medium transit frequency.
The 844 R Reversible automated system for sliding gates is an
electro-mechanical operator which transmits movement to the
sliding gate via a rack and pinion appropriately coupled to the
leaf.
The operation of the sliding gate is controlled by an electronic
control unit which can be built-in on board (462DF) or
connected in a remote position (578D or 462DF).
When, with the gate closed, the unit receives an opening
command by a radio-control or from another suitable device, it
activates the motor until the opening position is reached.
If automatic operating mode was set, the gate re-closes
automatically after the selected pause time has elapsed.
If the semi-automatic mode was set, a second pulse must be
sent for re-closing.
An opening pulse during re-closing, always causes movement
to be reversed.
A stop pulse (if supplied) always stops movement.
For details on sliding gate behaviour in different function logics,
consult the installation technician.
The automated systems include accessories and safety devices
(photocells, edges) that prevent the gate from closing when
there is an obstacle in the area they protect.
Manual opening is always possible, except in case of a fault. In
this case, the release system must be remedied.
The gearmotor has an adjustable mechanical clutch which,
when coupled to an electronic device, provides the necessary
anti-crushing safety, guaranteeing motion reversing for 2 sec.
both during closing and opening.
A magnetic sensor detects transit of the markers on the rack,
which correspond to the travel limit positions.
The warning-light indicates that the gate is currently moving. A
handy manual release facility makes it possible to move the
gate in the event of a fault.
MANUALOPERATION
If the gate has to be moved manually, due to a power-cut, it is
sufficient to push or pull it, because the reversible motor enables
the gate to be moved manually.
If the gate has to be moved manually due to a fault in the
automated system, use the release device as follows:
1) Open the electric lock with the key, checking if the gate is
free to move.
2) Open the protective door and fit the supplied key in the
lock as shown in Fig. 1.
3) Turn the key clockwise and pull the release lever as shown in
Fig. 2.
4) Open and close the gate manually.
RESTORING NORMAL OPERATION MODE
To prevent an involuntary pulse from activating the gate during
the manoeuvre, cut power to the system before re-locking the
operator.
1) Re-close the release lever.
2) Turn the key counter-clockwise.
3) Remove the key and close the lock protection door.
4) Move the gate until the release device meshes.
