IMPORTANT SAFETY INFORMATION

Important Safety Instructions

WARNING: TO REDUCE THE RISK OF SEVERE
INJURY OR DEATH:

• READ AND FOLLOW ALL INSTRUCTIONS.

• Never let children operate or play with the gate

controls. Keep remote controls away from children.

• Always keep people and objects away from the
gate. NO ONE SHOULD CROSS THE PATH OF A
MOVING GATE.

• Test the gate operator monthly. The gate MUST
reverse on contact with a rigid object or when an
object activates a non-contact sensor. If necessary,
adjust the force or the limit of travel and then retest
the gate operator. Failure to properly adjust and retest
the gate operator can increase the risk of injury or
death.

• Use the manual release mechanism only when the
gate is not moving.

• KEEP GATE PROPERLY MAINTAINED. Have
a qualied service person make repairs to gate

hardware.

• The entrance is for vehicles only. Pedestrians must
use a separate entrance.

• SAVE THESE INSTRUCTIONS.

Important Installation Instructions

1. Install the gate operator only when the following condi­tions have been met:

• The operator is appropriate for the type and usage
class of the gate.

• All openings of a horizontal slide gate have been
guarded or screened from the bottom of the gate to
a minimum of 4 feet (1.25 m) above the ground to
prevent a 2.25 inch (55 mm) diameter sphere from
passing through openings anywhere in the gate or
through that portion of the adjacent fence that the gate
covers when in the open position.

• All exposed pinch points are eliminated or guarded.

• Guarding is supplied for exposed rollers.

2. The operator is intended for installation on gates used by
vehicles only. Pedestrians must be provided with a sepa­rate access opening.

3. To reduce the risk of entrapment when opening and
closing, the gate must be installed in a location that allows
adequate clearance between the gate and adjacent struc­tures. Swinging gates shall not open outward into public
access areas.

4. Before installing the gate operator, ensure that the gate
has been properly installed and that it swings freely in
both directions. Do not over-tighten the operator clutch or
pressure relief valve to compensate for a damaged gate.

5. User controls must be installed at least 6 feet (1.83 m)
away from any moving part of the gate and located where
the user is prevented from reaching over, under, around or
through the gate to operate the controls. Controls located
outdoors or those that are easily accessible shall have
security features to prevent unauthorized use.

6. The Stop and/or Reset buttons must be located within
line-of-sight of the gate. Activation of the reset control
shall not cause the operator to start.

7. All warning signs and placards must be installed and
easily seen within visible proximity of the gate. A minimum
of one warning sign shall be installed on each side of the
gate.

8. For gate operators that utilize a non-contact sensor (photo
beam or the like):

• See instructions on the placement of non-contact
sensors for each type of application.

• Exercise care to reduce the risk of nuisance tripping,
such as when a vehicle trips the sensor while the gate
is still moving.

• Locate one or more non-contact sensors where the
risk of entrapment or obstruction exists, such as at the
reachable perimeter of a moving gate or barrier.

• Use only FAAC “Photobeam” photoelectric eyes to
comply with UL325.

FAAC MODEL 844 Slide Gate Operator

Important Installation Instructions (continued)

9. For gate operators that utilize a contact sensor (edge
sensor or similar):

• Locate one or more contact sensors where the risk
of entrapment or obstruction exists, such as at the
leading edge, trailing edge, and post mounted both
inside and outside of a vehicular horizontal slide
gate

• Locate one or more contact sensors at the bottom
edge of a vehicular vertical lift gate.

• Locate one or more contact sensors at the bottom
edge of a vertical barrier (arm).

• Locate one or more contact sensors at the pinch
point of a vehicular vertical pivot gate.

• Locate hard-wired contact sensors and wiring so
that communication between sensor and gate
operator is not subjected to mechanical damage.

• Locate wireless contact sensors, such as those
that transmit radio frequency (RF) signals, where
the transmission of signals are not obstructed or
impeded by building structures, natural landscaping
or similar hindrances. Wireless contact sensors shall
function under their intended end-use conditions.

• Use only FAAC MSE MO, CN60 or M60 edge
sensors.

MODEL 844 OPERATOR

1. DESCRIPTION & SPECIFICATIONS

These instructions apply to the following models:

844 ER Z16 CR, 844 R, 844 R CAT, 844 R RF

The FAAC Model 844 automated system for sliding
gates is an electro-mechanical operator transmitting
motion to the sliding leaf via a rack or chain pinion
appropriately coupled to the gate.

The non-reversing system ensures the gate is
mechanically locked when the motor is not operating
and, therefore, no lock needs to be installed.

The gearmotor is equipped with a mechanical
clutch which, combined with an electronic device,
offers the necessary adjustable anti-crushing
safety and guarantees stopping or reversing the
gate movement. A handy manual release makes it
possible to move the gate in the event of a power
cut or malfunction. The control board, if supplied
with the gearmotor, it is placed inside the operator.

The 844 automated system was designed and
manufactured to control access of vehicles. Avoid
any other use whatever.

Fig. 1

1.1. MAXIMUM USE CURVE

The curve makes it possible to establish maximum
work time (T) according to use frequency (F). The
844 gearmotor can operate non-stop at 70% use
frequency.

To ensure efcient operation, operate in the work

range below the curve.

Important: The curve is obtained at a temperature
of 75°F. Exposure to direct sunlight can reduce use
frequency down to 20%.

Calculating Use Frequency

The percentage of effective work time (opening +
closing) compared to total time of cycle (opening +
closing + pause times).

Calculation Formula

4. INSTALLING THE SYSTEM

4.1. PRELIMINARY CHECKS

To ensure safety and an efciently operating automated

system, make sure the following conditions are observed:

• The gate structure must be suitable for automation. For
example, wheel diameter must be in proportion to the
weight of the gate to be automated, an upper guide must
be provided, mechanical stop limits to prevent the gate
derailing must be installed.

• The soil must permit sufcient stability for the concrete

pad.

• There must be no pipes or electric cables in the pad
excavation area.

• If the operator is exposed to passing vehicles, install, if
possible, adequate means of protection against acciden­tal impact.

• Check if an efcient grounding is available for connec­tion to the gearmotor.

4.2. FOUNDATION PLATE INSTALLATION

1. Assemble the foundation plate as shown in Fig 4. The
foundation plate must be located as shown in Fig 5 (right
closing) or Fig 6 (left closing) to ensure that the rack and
pinion mesh correctly.

2. Prepare a concrete pad as shown in Fig.7, following
the suggested dimensions. It’s recommended to have
the pad a minimum of 4” above level grade to avoid any

ooding of the operator. The underground depth of the

concrete pad is determined by the soil condition and
the local building codes. Make sure the concrete pad is
leveled.

3. Provide one or more conduit pathways for all power and
accessory connections. Extend the conduit about of 1/2”
above the level of the concrete pad.

4. After the concrete is poured in the forms and before it
has a chance to set, insert the foundation plate into the

cement and position it ush with the top of the concrete

and aligned with the top of the lower gate frame. Use the
dimensions shown in Figs 5 or 6 to align your founda­tion plate. Allow the concrete to set for a minimum of two
days before installing the operator.

5. Route the wires in the conduits. To facilitate the connec­tions allow for about 15” of extra length of cables out of
the conduit. Separate the high and low voltage wires in
different conduits.

nection (see Section 6.5).
LAMP - (Terminals LAMP L, LAMP N): Flashing lamp

output same VAC as input; max 60W.

5.4.4. J1 Terminal Block - Accessories (Fig. 23)

Consult the relevant tables for a detailed description of
operation in the different logics

OPEN A - “Total Opening” Command (Terminal 1): any
pulse generator (push-button, detector, etc.) which, by clo­sing a contact, commands total opening and/or closing of the
gate leaf.

To install several total opening pulse generators, connect the
N.O. contacts in parallel (Fig. 35).

OPEN B - “Partial Opening” or “Closing” Command
(Terminal 2): any pulse generator (push-button, detector,

etc.) which, by closing a contact, commands partial opening
and/or closing of the gate leaf. In the B, C and B/C logics, it
always commands gate closure.

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 move­ment of the gate, or stop and restart the movement when it
is released (see advanced programming in Section 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
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 Section 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
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 the STOP
and - terminals.

SAFE - EDGE Safety Device Contact (Terminal 6):

The purpose of the "edge" safety device is to protect the
leaf movement area during 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 the
SAFE and - inputs (Fig. 26).

TX -FSW - Negative for Power Supply to Photocell
Transmitters (Terminal 11)

If you use this terminal to connect the negative transmitters
of the photocell power, you may, if necessary, also use the
FAIL SAFE function (see advanced programming in Section

5.5.2).

If this function is enabled, the equipment checks operation of
the photocells before every opening or closing cycle.

A.A. - Power Supply to Audio Alarm (Terminal 12)

Connect a 24 VDC - 125mA max audio alarm compliant with
UL325. 31.1.4. The alarm will sound upon two sequential ac­tivations of an entrapment protection device, continuosly until
the activation of a STOP command. To comply with UL325
the STOP input must be connected to a wired control located
in the line-of-sight of the gate.

OPENING PHOTOCELLS LOGIC:

Select the tripping mode of the opening photo­cells.

They operate for the opening movement only:
they stop the movement and restart it when they
are released, or they reverse it immediately.

= Reverse immediately to closing

= Restart movement on release

ENCODER:

If the encoder is present, you may enable its
use.

If the encoder is present and enabled, "decele­rations" and "partial opening" are controlled by
it (see relevant paragraphs).

The encoder operates as an anti-crushing de­vice. If the gate hits an obstacle during opening
or closing, the encoder immediately reverses
the gate leaf movement for 2 seconds. If the
encoder operates again during the 2-seconds
reversing time, the movement stops (STOP)
without commanding any reversing.

If no encoder is supplied, the parameter must
be set to . 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

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
obtaining greater deceleration precision.

= Deceleration disabled

From to = Deceleration enabled

PARTIAL OPENING:

You can adjust the width of partial leaf opening.

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 2' to 13'.

WORK TIME (time-out):

It is advisable 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 limit­switch and vice versa.

Adjustable from to sec. in one-second
steps.

Subsequently, display changes to minutes and
tens of seconds (separated by a point) and
time is adjusted in 10 second steps, up to a
maximum value of minutes.

Attention: the set value will not exactly
match the motor's maximum operating time
if decelerations are used.

ASSISTANCE REQUEST (combined
with next function):

If activated, at the end of countdown (see the
next function: "Cycle Programming") it effects
2 sec. (in addition to the value already set with

the PF function) of pre-ashing at every Open

pulse (job request). It can be useful to set
scheduled maintenance jobs.

= Active

= Disabled

CYCLE PROGRAMMING:

To set countdown of system operation cycles.
Settable (in thousands) from to
thousand cycles.

The displayed value is updated as cycles
proceed.

Post-limit switch 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
obtaining greater deceleration precision.

= Deceleration disabled

from to = Deceleration enabled

CLOSING limit-switch LED = FC1

Attention: Due to the powerful magnetic elds

produced by the supplied magnets, do not place magnetic

storage devices (credit cards, magnetic tapes, oppy

disks, etc) or sensitive electronic equipment (watches,
CRT monitors, LCD screens, etc.) near the magnets.

Notes on Magnet Positioning

• To ensure correct operation, allow at least 3/4 inch from the me­chanical stop limit in the gate stop position. Carry out this check
after determining the values of the pre- and post-limit switch
decelerations (see Section 5.5.2.) and after running at least one
complete cycle of the automated system.

• The distance between the limit-switch and magnets must be
from 1/4 to 1/2 inch.

• Magnets should be tted on the rack and not on the screws.

If necessary, position the magnet at the side of the screw and
adjust decelerations (see Section 5.5.2) in order to obtain the
correct stop point.

6.3. DETERMINING 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 motor to stop. The
device can be magnetic (Fig. 41) or inductive (Fig. 42).

6.3.1. Magnetic Limit-Switch (MLS)

The MLS limit-switch detects the transit of two magnets tted on the

side of the rack facing the operator.

Procedure for correct positioning of the two supplied magnets:

1. Check that the operator is in manual mode (see Section 8).

2. Manually open the gate to within 3/4 to 2 inches of the travel limit
mechanical stop.

3. Fit the magnet (without removing the protective lm 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 an additional 1 3/4 inches.

4. Manually close the gate to within 3/4 to 2 inches of the travel limit
mechanical stop.

5. Fit the magnet (without removing the protective lm 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 an additional 1 3/4 inches.

6. Move the gate to its halfway travel point and relock the system
(see Section 9).

7. Find out the desired pre- and post-limit-switch deceleration
values (see Section 5.5.2) and run the automated system for at
least one complete cycle.

8. Check that the gate stops approximately 3/4 to 2 inches from its
mechanical stop point. If necessary, correct the position of the
magnets and check that the stop point is correct.

9. Mark the position of the magnets on the rack, and remove them.

10. Clean the rack on its tting points, remove the lm 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).

Fig. 41

6.3.2. Inductive Limit-Switch

Operator 844 has an inductive limit-switch which detects the travel of

the two steel plates tted on the top of the rack.

Procedure for correct positioning of the two supplied steel plates:

1. Assemble the limit-switch by centering the plate with respect to
the threaded pins of the support (Fig. 42).

2. Check that the operator is in manual operating mode (see Sec­tion 8).

3. Manually open the gate to within 3/4 to 2 inches of 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 plate
forward an additional 1 3/4 inches and secure it to the rack by
tightening the screws.

5. Manually close the gate to within 3/4 to 2 inches of the mechani­cal stop limit.

6. Allow the plate to move on the rack in closing direction until the
relevant LED goes off (Figs. 22 and 42); next, move the plate
forward by an additional 1 3/4 inches and secure it to the rack by
tightening the screws.

FAAC MODEL 844 Slide Gate Operator

Notes on Plate Positioning

• To ensure correct operation, allow at least 3/4 inch from the me­chanical stop limit in the gate stop position. Carry out this check
after determining the values of the pre- and post-limit switch
decelerations (see Section 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 <
3/16 inch.

6.4. CHECK OF INPUTS

The table below shows the status of the LEDs in relation to to
the status of the inputs.

Note the following: Led ON = closed contact

6.6. MECHANICAL CLUTCH ADJUSTMENT

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 Sections 5.5.1 and

5.5.2.

Adjusting the Operating Threshold of the Mechanical Clutch:

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. A.

- To increase torque, turn the screw clockwise.

- To reduce torque, turn the screw counter-clockwise.

 The operator is supplied with the clutch set to maximum level.

Therefore, you must initially turn the screw counter-clockwise

to reach the best setting.

3. Power up the automated system and check that the torque you

have just set is correct.

 The operator is supplied as standard with a clutch adjustment

spring for gates up to 2200 lbs. For heavier gates, use the sup­plied alternative spring. For spring replacement instructions,

see Fig. 44 Ref. B.

A B

Fig. 44

6.7. CHECK OF STOP POINTS

Be careful when setting the post-limit-switch deceleration
and braking. If the deceleration is too long and braking is

insufcient, the magnet or steel plate tted on the gate's rack

can overshoot the sensor until it is disengaged. When the gate
stops, check that only the light limit-switch is engaged. The
relevant LED must be OFF. If it went OFF and then ON again,
or if both limit-switch LEDS are OFF, you must reduce the
post-limit-switch deceleration value and/or increase the braking
value (see Section 5.5.2).

6.8. SAFETY DEVICES AND ACCESSORIES
CHECK

Check for the correct operation of all safety equipment, anti­crushing devices (ENCODER sensor), and accessories used in
the system.

7. FINAL OPERATIONS

• After installation, apply the danger sticker to the top of the
cover (Fig. 45).

Fig. 45

• Snap-t the side panels, put the equipment's cover on

and secure it with the supplied screws (Fig. 46).

• Remove the vent stop screw (Fig. 47).

• Explain to the customer the correct operation and use of
the operator, and indicate the potentially dangerous areas
of the automated system.

2. Turn the key clockwise and pull the release lever as shown in Fig.

49.

3. Open and close the gate manually.

Fig. 49

9. RESTORING NORMAL OPERATION

To prevent an involuntary pulse from activating the gate, 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 engages.

Fig. 53

11.2. OIL TOP-OFFS

Periodically check the oil level inside the operator.

A once-a-year check is enough for medium or low usage. For
heavy duty usage, a check every 6 months is recommended.

To access the tank, temporarily remove the plastic oil ller cap

(Fig. 54).

Oil level is visually checked and must cover the copper coil of
the electric motor.

If more oil is needed, add it through the oil ller hole.

14. TROUBLESHOOTING

If you have a problem installing the operator, check the problems and solutions listed below for suggestions.

PROBLEM SOLUTIONS

A The operator does not respond to the

activating signal.

B The gate is closed and does not open. • Make sure the clutch adjustment is not too weak.

C The gate opens, but will not close. • If there are no optional reversing devices connected to the control

D The gate opens, but the operator con-

tinues to run.

• Make sure the main power switch is on.

• Check the control panel terminal strip for possible broken or discon-

nected wires.

• If a radio signal is being used to activate the operator, be sure the code
sets on both the transmitter and receiver are the same.

• Momentarily short across terminals 1 and 7 on the control panel. If
this activates the operator, a problem probably exists in the activating
device itself.

• Increase the torque if the motor is running and the gate is not moving.
This may be necessary for especially heavy gates.

• Check that the closed limit switch is working. The FC status light should
be off. Make sure that the limit switch plate is not too far away from the
limit switch. The distance between a plate and the switch should be
3/16 in.

• Check fuse F1 and replace it if necessary.

panel, make sure a jumper is installed between terminals 4 and 11 on
the control panel.

• If optional reversing devices have been installed, check them to see if
they are working properly (an activated reversing device will prevent
the gate from closing). Temporarily short across the relevant terminals
to bypass the reversing devices to see if the gate closes. If the gate
closes, then the problem exists within the reversing device(s).

• Check the FC light on the control panel. It should be OFF. If it is ON,
check the alignment of the limit switch plate.

• If the FCC light is ON and the limit switch plate is correctly adjusted,
replace the limit switch.

Note: If the limit switch plates are not detected by the limit switch on the
operator, the motor will run for 120 seconds and then the control panel will
be in alarm status.
