FITTING THE CONTROL BOX
The CB22 control board was designed for installation in a special box
under the cover of the sliding gate drive and can be ordered as an
accessory, if not already available.
The control board can also be fitted externally (on the wall) in a
waterproof box (203391).
The motor control unit is a highly modern electronic unit controlled by
a microprocessor. It has all wiring facilities and functions required for
safe operation. The control box with the motor control unit is mounted
with the cable entries facing down. It must not be permanently
exposed to direct sunlight. The electronics can be used for the
precise adjustment of the push-pull torque. The gate can be held by
hand if the fitting/setting is correct.
During operation, the gate can be stopped at all times via remote
control, push-button or key-operated switch. The gate wing requires a
firm stop for the “OPEN” and “CLOSED” positions.
ELECTRICAL INSTALLATION
The control board should be connected last of all, i.e. install the drive,
lay the required cables and attach the photocells (contact strips). For
a fixed fitting, an accessory is required for the disconnection from the
mains that has a contact spacing of at least 3 mm (main switch).
Moisture and water will destroy the control board. Make
sure under all circumstances that water, moisture or storage moisture
cannot penetrate the control board. All openings and
cable entries must be sealed watertight.
The following minimum cable cross-sections should be used:
• 100-230 volts 1.5mm² or more more
• 0-24 volts 0.5mm² or more more
Tips: Bell wires often cause problems when used, because they lose
too much voltage if lines are long. Disconnect the cables in the cable
trunkings i.e. the motor cable and the cable for the photocell, in
particular for key-operated switches and start buttons (coming from
the house), otherwise malfunctions are possible if lines are long.

PLEASE START BY READING THESE IMPORTANT SAFETY RULES • SAVE THESE INSTRUCTIONS
This safety alert symbol means "Caution" - failure to comply with such an instruction involves risk of personal injury or damage
to property. Please read these warnings carefully.
This gate drive mechanism is designed and tested to offer appropriately safe service provided it is installed and operated in
strict accordance with the following safety rules.
Incorrect installation and/or failure to comply with the following instructions may result in serious personal injury or property
damage.
Installation and wiring must be in compliance with
your local building and electrical installation codes.
Power cables must only be connected to a properly
earthed supply.
Any entrapment possibility by the moving wing between
wing & walls must be secured with safety edges or IR-
sensors..
Disconnect electric power to the system before making
repairs or removing covers.
A disconnecting device must be provided in the
permanently-wired installation to guarantee all-pole
disconnection by means of a switch (at least 3mm
contact gap) or by a separate fuse.
When using tools and small parts to install or carry
out repair work on a gate exercise caution and do not
wear rings, watches or loose clothing.
Make sure that people who install, maintain or
operate the gate drive follow these instructions. Keep
these instructions in a safe place so that you can refer to
them quickly when you need to.
Please remove any locks fitted to the gate in order to
prevent damage to the gate.
It is important to make sure that the gate always runs
smoothly. Gates which stick or jam must be repaired
immediately. Employ a qualified technician to repair the
gate, never attempt to repair it yourself.
Keep additional accessories away from children. Do not
allow children to play with pushbuttons or remote controls.
A gate can cause serious injuries as it closes.
After the installation a final test of the full function of
the system and the full function of the safety devices
must be done.
The full protection against potential squeeze or
entrappment must work direct when the drive arms
are installed.
This drive cannot be used with a gate incorporating a
wicket door unless the drive cannot be operated with
the wicket door open.
IMPORTANT FITTING AND OPERATING INSTRUCTIONS

GB-2
TYPICAL CONFIGURATION OF A UNIT
1. Drive with control board
The drive is located on a height-adjustable mounting plate
2. Control board (if mounted externally)
If the control board is mounted externally (external mounting box
required), the cables and feeder cables must be laid correctly
3. photocell (770E/771E) 150-200 mm (optional)
First photocell. Protects people
4. photocell (770E/771E) 700 mm (optional)
Second photocell. Protects vehicles and higher objects
5. Flashing light
Important visual information on the movement of the gate
6. Contact strip (optional)
Safeguards the gate on being touched. Contact strips can be mounted
on the gate or on the pillars. If the gate has openings exceeding
45mm, a contact strip is required on the pillar (accessory). If required,
contact strips must be mounted at a height of up to 2.5m.
7. Key-operated switch (optional)
Is mounted on the outside. The gate is opened by key or by entering a
number.
8. photocell (optional)
Safeguards the gate on opening. This photocell can be omitted if the
construction itself prevents people from being present in this area. A
contact strip can be fitted here as an alternative option.
The control board complies with the latest EU directives. On
of these directives specifies that the closing forces at the gate edge
must not exceed 400 N (40 kg) for the last 500 mm before the gate is
CLOSED. Above 500 mm, the maximum force at the gate edge must
not exceed 140 N (140 kg). If this cannot be ensured, a contact strip
must be mounted on the gate at a height of up to 2.5 m or on the
opposite pillar (EN12453).
MOTOR
Connect the motor to the control board exactly as shown on the
connection layout diagram.
Terminal 4 cable black
Terminal 5 cable blue
Terminal 6 cable brown
The cable for the capacitors supplied with the motors must be
inserted in terminals OP and CL together with the cables for the
direction of rotation. Make sure that it is connected correctly and
powered sufficiently. The capacitor is responsible for the force that
the motors have later on.
Note: If drives/motors other than ours
are connected, it might be required to swap the cables of terminals 4
+ 6 to ensure correct operation. This is shown during “Initial
operation”, if the control board does not maintain the correct moving
directions. See also the Limit switch connection instructions for more
information.
LIMIT SWITCH CONNECTION
2005 design: The cable is connected to terminal CN2 using the
connector.
Other designs: There is no connector on the limit switch. On
purchasing a single control board, a connector is provided with a
short cable. Both cables are connected by means of a soldered
connection or a block terminal. Different types of limit switch
systems can be connected to the control board. The limit switch has
to have 2 contacts NC (normal closed). See the illustration for the
correct connection.
Position of the magnets on the gate for magnetic limit switch:
The magnet with the designation 1 must always be fixed on the left
side of the rack bar.
The magnet with the designation 2 must always be fixed on the right
side of the rack bar.
Note: The correct operation of the control LED should be re-
checked before initial operation.
Note: In order to have the correct direction for OPEN, check the
setting of DIP7.

POTENTIOMETER
PT1 (TRIMMING POTENTIOMETER 1): BRAKE
When the gate reaches its limit switch, the drive shuts down.
Depending on weight and function of the gate, it may continue to
move on a bit further before stopping. The brake function is for the
active braking of the gate in order to minimise this additional
movement. Left stop = brake OFF.
PT2 (TRIMMING POTENTIOMETER 2): AUTOMATIC CLOSING
(TIMER TO CLOSE)
The waiting time for the gate for GATE OPEN can be defined.
The gate is closed 0-150 sec. after the set time expires.
Only possible if a photocell is connected (771E/770E).
(Not possible for self-hold and channel separation)
PT3 (TRIMMING POTENTIOMETER 3): FORCE SETTING
Definition of the force with which motor is to operate. The required

ACCESSORIES
GB-6
PHOTOCELLS (OPTIONAL)
The photocells are for safeguarding the gate and must be used. The
fitting location depends on the gate’s design. EN12453 specifies that
a pair of photocells must be installed at a height of 200mm; a second
pair must be installed in the same position at a height of 700mm. A
third pair of photocells can be optionally installed. The photocells
consist of a transmitter and a receiver and must be opposite each
other. The housing of the photocell (plastic) can be opened using a
screwdriver. The photocell is mounted on the wall using small screws
and wall plugs. It is possible to use two different photocell systems.
(see Dip switch description). To enable the “Automatic closing”
function, the Chamberlain failsafe photocell must be installed. A
combination of photocells is not possible. The Chamberlain failsafe
system (2-cable system) has small LEDs (light) that can be seen from
the outside on both sides to indicate the status of the photocell. Two
Chamberlain failsafe photocell models are available. The one model
is ideal for walls lying opposite. The other model is ideal for the inside
of the gate, because fittings are already available.
Diagnosis at the Chamberlain failsafe photocell
LED constant = OK
LED flashes = photocell disables control board
LED off = no current, incorrect connection or polarity
Diagnosis on the control board
LED off = OK
LED on constantly = control board disables
LED flashes = OK no photocell connected
Cable cross-section: 0.5 mm2or more.
Voltage: 12/24 volts AC/DC.
Do not use any fixed copper lines. Do not lay any 230 volt cables in
parallel and do not lay any 2 cables in the same cable trunking.

JUMPERS
Programming of failsafe photocells model 771E/770E
1.Before the Initial Setup
2.When connecting or removing photocell(s)
- Switch off control board ( disconnect from current)
- Slip jumper on designated pins
- Dipswitch 5 to “ON”
- Connect photocell(s) according illustration
- Reconnect control board, wait short-time
- Pull jumper, wait short-time
Done! (The number of photocells connected are stored)
Programming of relay photocells such as 100263
The control board must be disconnected from the mains for a few
seconds. All terminals to which no photocell is connected must be
bridged with COM. (16-19,17-19,18-19). The power supply for the
relay photocell of terminals 14-15. Dip switch 5 must be at OFF.
The jumper must be unplugged.
Note: Relay photocells are no longer permitted for new installations
as per EN12978, because they cannot perform self-checks (failsafe).
Operation without photocells
DANGER: Not permitted for normal operation. In this case contact
strips must safeguard the gate.
The control board must be disconnected from the mains for a few
seconds. Terminals 16-17-18-19 must all be bridged. Dip switch 5
must be at OFF. The jumper must be unplugged.
Note: It is not possible to combine different photocell models.

GB-7
PUSHBUTTON / KEY-OPERATED SWITCH (OPTIONAL)
The control board / drive can be activated using various inputs.
This can be done using a hand-held transmitter or key-operated
switch (terminals 7+10).
Hand-held transmitter = see Teaching the hand-held transmitter
Switch input 1 = input control 1. Normal operation
Switch input 2 = input control 2. Active for special settings
(see Dip switch description)
EMERGENCY STOP (OPTIONAL) 600084
A switch can be connected to stop or disable the unit. The movement
of the wings is stopped immediately. Terminals 9 and 10 must be
bridged if no switch is installed.

GB-9
INITIAL OPERATION/BASIC SETTING
Proceed step by step. If you are not sure, start again at the
beginning. Take sufficient time to make these settings.
1. Are all components required for operation connected? Motor(s),
photocell (!), flashing light, push-button or switch etc?
2. Make sure that nobody is present in the range of the gates.
3. Check whether the LEDs (lamps) are working correctly or whether
they are blocking a function. RED LEDs should be off, green LEDs
should be on. ( with the exception of the LEDs for the limit switch
status - yellow)
4. Set the dip switch to the standard program, if not already done on
delivery: 1= “ON”, 2=”ON”, 3=”OFF”.
Any changes can be made late. (see Dip switch description)
5. Dip switch 7 determines the direction of opening
(see Dip switch description)
6. Set the force at the potentiometer “FORCE “ to max. 30%. Even
lower if the gates are very light. Try before correcting. Only increase
the force in small steps.
7. Switch off control board (cut from current)
7.1 Slip jumper on designated pins
7.2 Change Dipswitch 5 to “ON”
7.3 Connect photocell(s) according to illustration
7.4 Reconnect control board to current, wait short-time
7.5 Pull jumper, wait short-time. The LED(s) of the photocell(s)
connected stay(s) out. The LED(s) of the photocell(s) not connected
will flash. Done!
Programming the time for the covered distance
1. Unlock the gate and move it manually to the limit switch. This is
how you check whether the limit switch for OPEN/CLOSED is
displayed at the correct LED
. If the right limit switch has been activated, the corresponding LED
goes out.
2. Move the gate again manually between the limit switches “OPEN”
and “CLOSED” and lock it. (Both limit switches must remain free.)
3. Press button L1 briefly (1 second), the gate opens. If the gate
reaches the “OPEN” limit switch, it stops briefly and then closes again
automatically. Once the gate reaches the “OPEN” limit switch, the
programming process is completed.
ATTENTION: If the gate closes instead of opening, dip switch 7
must be moved to the other position! Then restart programming
again from the beginning with step 1.
The time for the required covered distance has now been
programmed. The soft stop (slow run) is programmed automatically
approx. 4-5 seconds before the limit switch is reached. It can then be
activated via dip switch. (see Dip switch description)
Completion of the installation/programming:
Once the covered distance is programmed, the hand-held
transmitters can be programmed (not required for kits) or deleted.
1. Start the gate with the hand-held transmitter or a connected button
and observe the process. Close the gate again WITHOUT having
made any settings.
Note1: The gate does not react (see photocell description jumper).
Note2: If the gate now only reacts with one switch (terminals 7+10),
either the radio has not been programmed/is not available or the
radio module is not plugged in correctly.
2. If the gate does not close completely by itself, adjust the
potentiometer to other values, adapted to fit the experience value
from the test. (force correction)
3. Now start a second attempt and proceed as above. Close the gate
first before you make any settings.
4. Once all settings have been made, check the function of
photocells, buttons, flashing lamp, hand-held transmitter, accessories
etc. If you desire automatic closing, turn the “TIMER TO CLOSE”
potentiometer in clockwise direction. You can set the rest time
between 0 and 150 seconds, as desired.
Also make these settings with the gate closed.
5. Show all persons that use the gate how the gate moves, how the
safety functions work and how to operate the drive by hand.

2. Find and rectify fault(s) (see description
of LEDs).
3. Check photocell connection /
programming.
4. Connect simple jumper.
5. Check terminals and connections.
The gate opener stops suddenly and then restarts
only after a lengthy pause.
If the gate is operated constantly, the motor
will reach its cut-off temperature - protective
facility - as the gate opener is not designed
for permanent operation.
Allow motor sufficient time to cool (min. 15
minutes).
How long is the probable service life of a gate opener? When used for private purposes, a correctly installed gate opener can
operate perfectly for in excess of 10 years. Both the gate and the gate
opener must be checked regularly and serviced in accordance with
their respective instructions.
What happens in case of power failure? All Chamberlain gate openers are equipped with a release system by
means of which the gate can be operated manually in case of power
failure.
How long does it take to install a gate opener? Depending on your specific technical skills, the installation of the
mechanical components can take approx. 3 to 8 hours. Firstly, the gate
needs to be properly prepared such that installation work can
commence. The electrical connection work takes approx. 1 to 2 hours.
Each user should be instructed for at least 30 minutes with regard to
the operation of the gate opener, whereby its functionality should be
demonstrated and safety aspects, protective facilities and procedure in
case of power failure should all be explained.
Is it possible to open wing for pedestrian mode? Yes, it is possible. This process can be operated via remote control (a
2-channel remote control is the minimum requirement here) or via
switch operation (see “Standard & pedestrian mode”)

The wing does not open completely. 1.Is the door travel programmed
correctly?
2.Is the force adjusted correctly?
1. Program door travel again
2. Increase force (under wind load the
operator may run a bit slower)
(Remote controlled) universal receiver does not work Observe polarity (terminals 14/15) Swap “+” and “-” cables
The gate must follow a slope. Not recommended! Change gate! The gate can move in an uncontrolled (dangerous) manner
if the gate opener has been released. A stronger force is needed in the upwards direction of
the slope and then, in the opposite direction, the gate opener’s force is too strong.
The force setting has been altered, but no
difference is apparent.
Disconnect the controller from the power supply for a few seconds in order to activate the
control board’s self-diagnosis functionality.
The remote control’s range is too short. The installation of an external aerial is recommended as the controller with the short cable
aerial is located either behind the post or near ground level in most cases. The optimum
location of the aerial is as high as possible in all cases. An appropriate aerial with installation
kit can be obtained from Chamberlain as an accessory with the product ref. no. ANT4X-
1EML.
