5.4.1. Connection of photocells and safety devices
Before connecting the safety devices and photocells we advise
you to select the type of operation according to the movement
area they have to protect (see fig.24 for example):
Opening safety devices: they are tripped when an obstacle is
detected only during gate opening movement. They
cause immediate closure and resumption of opening
motion on release (see programming in par. 5.5.2.)
Closing safety devices: they are tripped when an obstacle is
detected only during gate closing movement. They
cause re-opening, either immediate or on release
(see programming in par. 5.5.2.)
Opening/closing safety devices: they are tripped during the
gate opening and closing movements. They cause
stopping and restart motion on release.
"Edge" safety devices: they are tripped during the gate opening
and closing movements. They cause immediate
reversal of motion and stopping after two seconds.
Encoder: it is tripped if there is an obstacle during gate opening
and closing movements. It causes immediate reversal
of motion and stopping after two seconds.
N.B. If two or more safety devices have the same function
(opening, closing, opening and closing, edge), the contacts
must be connected to each other in series (fig. 25).
N.C. contacts must be used.
N.B: If safety devices are not used, jumper connect the terminals
as shown in fig. 26.

5.4.2. J7 Terminal board - Power supply (fig. 23)
POWER SUPPLY (terminals PE-N-L):
PE: Earth connection
N:Power supply ( Neutral )
L:Power supply ( Line )
NB.: For correct operation, the board must be connected to
the earth conductor in the system. Install an adequate
differential thermal breaker upstream of the system.
To install several partial opening pulse generators,
connect the N.O. contacts in parallel (fig.35).
FSW OP - Opening safety devices contact (terminal 3): The
purpose of the opening safety devices is to protect the
leaf movement area during opening. During opening, in
the A-AP-S-E-EP logics the safety devices reverse the
movementof the gate,or stop and restart the movement
when it is released (see advanced programming in
Chpt. 5.5.2). During the opening cycle in logicsthe B, C
and B/C, they interrupt movement. They never operate
during the closing cycle.
If the Opening safety devices are engaged when the
gate is closed, they prevent the opening movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).
NB.: If no opening safety devices are connected, jumper
connect inputs FSW OP and -TX FSW (fig. 26).
FSW CL - Closing safety devices contact (terminal 4): The
purpose of the closing safety devices is to protect the
gate movement area during closing. During closing, in
the A-AP-S-E-EP logics, the safety devices reverse the
movement of the gate, or stop and reverse the
movement when it is released (see advanced
programming in Chpt. 5.5.2). During the closing cycle in
logics B, C and B/C, they interrupt movement. They
never operate during the opening cycle. If the Closing
safety devices are engaged when the gate is open,
they prevent the closing movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).
NB.: If no closing safety devices are connected, jumper
connect terminals FSW CL and -TX FSW
(fig. 26).
STOP - STOP contact (terminal 5): any device (e.g. a push-
button) which, by opening a contact, stops gate
movement.
To install several STOP devices, connect the N.C.
contacts in series (fig. 25).
NB.: If STOP devices are not connected, jumper
connect the STOP and -terminals.
SAFE - EDGE safety device contact (terminal 6): The purpose of
the "edge" safety device is to protect the leaf movement
areaduring opening/closing. In all logics, during opening
and closing, the safety device reverses gate movement
for 2 seconds. If the safety devices operate again during
the 2-seconds reversing time, it stops movement (STOP)
without any reversing.
If the Edge safety device is engaged while the gate is
closed or open, it prevents movement.
To install several safety devices, connect the N.C.
contacts in series (fig.25).
NB.: If edge safety devices are not connected, jumper
connect the SAFE and - inputs (fig. 26).

OPENINGPHOTOCELLS LOGIC:
Select the tripping mode of the opening
photocells.
Theyoperate for the opening movement only:
they stop the movement and restart it when
theyare released,orthey reverseitimmediately.
= Reverse immediately to closing
= Restart movement on release
ENCODER:
If the encoder is used, you may select its
presence.
If the encoder is present and enabled,
"decelerations" and "partial opening" are
controlled by the encoder (see relevant
paragraphs).
The encoder operates as an anti-crushing
device: If the gate strikes an obstacle during
openingor closing, theencoder immediately
reverses gate leaf movement for 2 seconds.
If the encoder operates again during the 2-
seconds reversing time, it stops movement
(STOP) without commanding any reversing.
If no sensor is supplied, the parameter must
be set on . If there is the encoder, adjust
the sensitivity of the anti-crushing system, by
varying the parameter between
(maximum sensitivity) and (minimum
sensitivity).
from to = Encoder active and
sensitivity adjustment
= Encoder disabled
Note 1: to reset the programming default settings, check if the
edge input is closed (SAFE LED ON), and simultaneously
press keys +, - and F, holding them down for 5 seconds.
Note 2.: modification of programming parameters comes into
effectimmediately, whereas definitive memory storage
occurs only when you exit programming and return to
gate status viewing. If the equipment is powered down
before return to status viewing, all modifications will be
lost.
Pre-limit switch DECELERATION:
You can select gate deceleration before the
opening and closing limit-switches have been
tripped.
Time can be adjusted from to in
0.1-second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaininggreater deceleration precision.
= Deceleration disabled
from to = Deceleration enabled
Post-limitswitch DECELERATION:
You can select gate deceleration after the
opening and closing limit-switches have been
tripped.
Time can be adjusted from to in
0.1-second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaininggreater deceleration precision.
= Deceleration disabled
from to = Deceleration enabled
ASSISTANCE REQUEST (combined with next
function):
If activated, at the end of countdown
(settable with the next function i.e. "Cycle
programming") it effects 2 sec. (in addition
to the value already set with the PF function)
of pre-flashing at every Open pulse (job
request). Can be useful for setting scheduled
maintenance jobs.
= Active
= Disabled
WORK TIME (time-out):
We advise you to set a value of 5 to 10 seconds
over the time taken by the gate to travel from
the closing limit-switch to the opening limit-
switchand vice versa.
Adjustablefrom to sec. in one-second
steps.
Subsequently,displaychanges to minutes and
tensof seconds (separatedbyapoint) and time
isadjustedin10second steps, up to a maximum
value of minutes.
Attention: the set value does not exactly
matchthe motor's maximum operating time,
because the latter is modified according to
the performed deceleration spaces.
PARTIALOPENING:
Youcan adjust the widthofpartialleafopening.
Time can be adjusted from to in
1-second steps.
If an encoder is used, the adjustment is not
determined by time but by motor revs, thus
obtaining greater partial-opening precision.
For example, with pinion Z20, partial opening
can vary from about 60 cm to 4 m.
CYCLEPROGRAMMING:
For setting countdown of system operation
cycles. Settable (in thousands) from to

6. START-UP
6.1. ELECTRIC CONNECTIONS
Make all electrical connections to the board as in chapter 5,
including earthing of the operator (Fig. 39).
6.3.2. Inductive limit-switch
Operator 844 has an inductive limit-switch which detects the
transit of the two steel plates fitted on the top of the rack.
Procedure for correct positioning of the two supplied steel
plates:
1) Assemble the limit-switch by centring the plate with respect
to threaded pins of the support (Fig. 42).
2) Check if the operator is in manual operating mode (see
chapter8).
3) Manually move thegate to openingposition, allowing 2 -5 cm
from the mechanical stop limit.
4) Allow the plate to move on the rack in opening direction until
the relevant LED goes OFF (Figs. 22 and 42); next, move the
plateforwardbyaboutanother 45 mm and secure it to the rack
bytightening the screws.
5) Manually move the gate to closing position, allowing 2 - 5 cm
from the mechanical stop limit.
6) Allow the plate tomoveonthe rack in closing directionuntilthe
relevant LED goes OFF (Figs. 22 and 42); next, move the plate
forward by about another 45 mm and secure it to the rack by
tighteningthescrews
Attention: due to the powerful magnetic fields the supplied
magnets produce, the 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.
Notes on magnet positioning
• To ensure correct operation, allow at least 2 cm from the
mechanical stop limit in the gate stop position. Carry out this
check after determining the values of the pre- and post-limit
switchdecelerations (see par. 5.5.2.) and after running at least
one complete cycle of the automated system.
• The distance between the limit-switch and magnets must
befrom 5 to 12 mm.
• Magnets should be fitted on the rack and not on the fixing
screws. If necessary, position the magnet at the side of the
screw and adjust decelerations (parag. 5.5.2) in order to
obtain the correct stop point
6.3. DETERMINING THE STOP POINTS AT TRAVEL LIMIT
Operator 844 has a limit sensor switch which, by detecting the
transit of a reference applied to the rack, commands the gate
motor to stop. The device can be MLS (fig. 41) or inductive (fig.
42).
6.3.1. MLS limit-switch
The MLS limit sensor switch detects the transit of two magnets
fitted on the side of the rack facing the operator.
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 travel limit mechanical stop.
3) Fit the magnet (without removing the protective film from
the adhesive side) on the side of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in opening direction until the relevant LED goes off
(Fig. 22 and 41), then move the magnet forward a further
45 mm.
4) Manually take the gate to closing position, leaving 2 - 5 cm
from the travel limit mechanical stop.
5) Fit the magnet (without removing the protective film from
the adhesive side) on the side of the rack facing the
operator, aligning the upper edges. Slide the magnet on
the rack in
closing direction until the relevant LED goes off (Fig. 22 and
41), then move the magnet forward by about a further 45
mm.
6) Take the gate to its halfway travel point and relock the
system (see chapter 9).
7) Find out the desired pre- and post-limit-switch deceleration
values (see parag. 5.5.2) and run the automated system
for at least one complete cycle.
8) Check if the gate stops at about 2 - 5 cm from its mechanical
stop point. 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. 41 ref. 1) and re-
position the magnets with the adhesive strip in contact
with the rack (fig. 41 ref. 2).

7. FINAL OPERATIONS
At end of installation, apply the danger sticker on the top of
the cover (Fig. 45).
6.7. CHECK OF STOP POINTS
Take care over the setting of the post-limit-switch deceleration
and braking: If deceleration is too long and braking is insufficient,
the reference fitted on the gate's rack (magnet or steel plate)
can overtake the sensor until the latter is disengaged. When
the gate stops, check if only the limit-switch involved is engaged.
The relevant LED must be OFF - if it went OFF and then ON
again, or if both the limit-switch LEDS are OFF, you must reduce
the post-limitswitch deceleration value and/or increase braking
value (see par.5.5.2).
6.8. SAFETY DEVICES AND ACCESSORIES CHECK
Check correct operation of all the safety and anti-crushing
devices (ENCODER sensor), and of the accessories used on the
system.
Snap-fit the side panels, fit the equipment's cover and fit the
cover with the supplied screws (Fig. 46).
Remove the vent stop screw (fig. 47).
Hand the "User's Guide" to the Customer, explain correct
operation and use of the gearmotor, and indicate the
potentially dangerous areas of the automated system.
Notes on plate positioning
• To ensure correct operation, allow at least 2 cm from the
mechanical stop limit in the gate stop position. Carry out this
check after determining the values of the pre- and post-limit
switchdecelerations (see par. 5.5.2.) and after running at least
one complete cycle of the automated system.
• The distance between the limit-switch and the plates must
be < 5mm.

6.6. ADJUSTMENT OF MECHANICAL CLUTCH
In addition to its electronic safety devices (encoder and force
adjustment), the 844 operator is also equipped with a
mechanical clutch.
For gate force and the encoder, please consult paragraphs
5.5.1 and 5.5.2.
Procedure for adjusting the operating threshold of the
mechanical clutch (you are recommend to set it to conform
with current regulations):
1) Cut electrical 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
as shown in Fig. 44 Ref 44.
To increase torque, turn the screw clockwise.
To reduce torque, turn the screw anti-clockwise.
ÜThe operator is supplied with the clutch set to maximum
level. Therefore, you must initially turn the screw anti-
clockwise to reach the best setting.
3) Power up the automated system and check that the torque
you have just set is correct.
Ü The operator is supplied as standard with a clutch adjustment
spring for gates up to 1000 kg. For heavier gates, use the
supplied alternative spring. For spring replacement
instructions, see Fig. 44 Ref. B.

or malfunction of the automated system, use the release
device as follows:
1) Open the protection door and fit the supplied key in the
lock (Fig. 48).
2) Turn the key clockwise and pull the release lever as shown
in Fig. 49.
3) Open and close the gate manually.
10.INSTALLING THE CN 60E CONTROL UNIT (OPTIONAL)
The operator is designed to house (with the aid of a DIN bar)
the CN 60E control unit of the safety conductive edge. Cut the
DIN bar to measure and secure it to the operator with two
screws in the appropriate holes and attach the CN 60E control
unit to it (Fig. 50).
For connection and operation, refer to the specific instructions.
Fig. 52
Fig. 51
11. INSTALLING REMOTE BOARD 578D
If you prefer to install the control board separately from the
operator, you must use remote board 578D. In this case, an
interface card is fitted on board the operator (fig. 51).
For connections from the interface card to the remote board,
please refer to the specific instructions on the 578D board.
12. INSTALLING BOARD 462DF
If you wish to install the 462DF control board on the operator,
you must use the appropriate adapter kit (Fig. 52).
To install it, refer to the specific instructions.

15.REPAIRS
For any repairs, contact the FAAC authorised Repair Centres.
14. MAINTENANCE
Check the operational efficiency of the system at least once
every 6 months, especially as regards the efficiency of the
safety and release devices (including operator thrust force).
14.1. DISASSEMBLING THE TRANSFORMER-BOARD UNIT
If you have to disassemble the transformer-board unit, proceed
as follows:
Remove all terminal boards and connectors from the board.
Unscrew the 3 securing screws of the board and the 2 of the
transformer. Lift the unit up and gently remove the transformer
from the couplings on the board as shown in Fig. 53.
14.2. OIL TOP-UPS
Periodically check oil level inside the operator.
A once-a-year check is enough for medium or low use
frequency. For heavier duty, every 6 months is recommended.
To access the tank, temporarily remove the oil filling plug (Fig.
54).
Oil level (visually checked) must be in line with the copper
windings of the electric motor.
To top up, pour in oil up to the required level.
Use FAAC XD 220 oil only.

USER’SGUIDE
AUTOMATED SYSTEM 844
Read the instructions carefully before using the product and
keep them for future consultation.
GENERAL SAFETY REGULATIONS
If installed and used correctly, the 844 automated system will
ensure a high degree of safety.
Some simple rules regarding behaviour will avoid any accidental
trouble:
- Do not stand near the automated system and do not allow
children and other people or things to stand there, especially
while it is operating.
- Keep radiocontrols or any other pulse generator well away
from children to prevent the automated system from being
activated involuntarily.
- Do not allow children to play with the automated system.
- Do not willingly obstruct gate movement.
- Prevent any branches or shrubs from interfering with gate
movement.
- Keep illuminated signalling systems efficient and clearly visible.
- Do not attempt to activate the gate by hand unless you have
released it.
- In the event of malfunctions, release the gate to allow access
and wait for qualified technical personnel to do the necessary
work.
- After enabling manual operating mode, switch off the power
supply to the system before restoring normal operating mode.
- Do not make any alterations to the components of the
automated system.
- Do not attempt any kind of repair of direct action whatsoever
and contact FAAC qualified personnel only.
- Call in qualified personnel at least every 6 months to check
the efficiency of the automated system, safety devices and
earth connection.
DESCRIPTION
The 844 automated system is ideal for controlling vehicle
access areas of medium transit frequency.
The 844 automated system for sliding gates is an electro-
mechanical operator transmitting motion to the sliding gate
via a rack or chain pinion appropriately coupled to the gate.
Operation of the sliding gate is controlled by an electronic
control equipment housed inside the operator.
When, with the gate closed, the equipment receives an
opening command by radiocontrol 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 to close the door again.
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.
The system ensures mechanical locking when the motor is not
operating and, therefore, no lock needs to be installed.
Manual opening is, therefore, only possible by using the release
system.
The gearmotor is equipped with an adjustable mechanical
clutch which, combined with an electronic device, offers the
necessary anti-crushing safety, by guaranteeing reversal of
closing motion or stopping of opening motion.
A sensor detects transit of the references fitted on the rack,
which correspond to the travel limit positions.
The electronic control equipment is housed in the gearmotor.
A handy manual release makes it possible to move the gate in
the event of a power cut or malfunction.
The warning-light indicates that the gate is currently moving.
MANUAL OPERATION
If the gate has to be operated manually due to a power cut or
malfunction of the automated system, use the release device
as follows:
1) Open the protection door and fit the supplied key in the
lock as shown in Fig. 1.
2) Turn the key clockwise and pull the release lever as shown
in Fig. 2.
3) Open and close the gate manually.
RESTORING NORMAL OPERATION
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 anti-clockwise
3) Remove the key and close the lock protection door.
4) Move the gate until the release meshes.
