BEFORE YOU BEGIN
• Ensure the gate is in working order and suitable for automation.
Check that any wheels are in good working order, the track is free from obstruction and that the gate moves
smoothly throughout itʼs travel. If not, have the gate serviced by a gate installer.
• Ensure the motor you are installing is suitable for the gate weight and duty cycle.
Operating frequency / Duty cycle: MGS Sliding gate drives have a maximum duty cycle of approx. 30% (i.e. 30% per
hour) and not intended for commercial applications.
CAUTION: This device is not intended to run in high duty cycle applications, frequent activations may engage the units
Thermal overload circuit. When this occurs the unit will cease operations until such time as the motor cools.
• Gate size: When calculating the gates weight allow for the gateʼs length, a light weight long gate (long = + 5m)
needs far greater force to set it in motion than a short gate or heavy gate.
• Gate weight: Ensure that allowance is made not only for the gateʼs weight but its length and mobility.
Example: A
light gate that slides poorly is likely to need a stronger drive than a heavy, smooth-sliding gate.
NOTE: Gate weight is only an approximate indicator, the actual relevance of which can vary greatly.
• Climatic conditions. Gate operating in high wind areas may be affected by side pressure on the gate. Timber or
metal lined gates may require additional force to operate in high winds. It is essential that this is allowed for before
installation.
• Temperature: Extreme low outdoor temperatures can make it difficult to get the operate the gate due to changes in
the ground conditions. A stronger drive again might be necessary.
High outdoor temperatures can cause the thermal protection mechanism to be activated sooner.
• Safety: Your CB22 control board has outputs for flashing lamp as well as safety inputs for, contact strips, loop detectors
and photo electric safety beams (1 set of PE beams is provided). Please ensure that you comply with the standards and
regulations relevant to your particular installation.
• Control unit: The control unit was developed specifically with safety aspects in mind.
It is located in the motor
housing and is factory defaulted for a Right hand gate configuration (see page 6)

Positioning the motor and plinth.
Before preparing the plinth for use ensure that you have the correct
orientation and location for the motor.
No part of the motor or pinion should extend past the gate.
The motor plinth and all electronics should be located within the
propertyʼs boundaries.
The motor can be adjusted up and down and back and forth to some
degree however planning the location of your plinth and conduit exit will
save you time and effort.
Installing the base plate.
Where possible the base plate provided should be
installed into a concrete plinth. The plate has been
manufactured to provide a stable anchorage for the
motor whilst also provided for easy adjustment of pinion
to the rack.
The Base plate should be installed into a concrete plinth
of approximate 50cm x 50cm x 50cm for maximum
strength.
Ensure that a conduit is installed before adding the
concrete and that the exit point for the conduit is on the
correct side of the base plate in relation to the motor.
The plate has two recesses, ensure that the conduit
exits to the rear of the motor, this will facilitate the
passage of wire through the grommet located at the
base of the control box housing.
NOTE: For best results make sure the plinth
is level and has adequate drainage. Pooled
water around the base of the motor will
damage the gate motor.

Mounting the Rack
To ensure the best gate travel the rack should follow the gates
movement. The rack should be fastened to the gate in section
follow the contours of the gateʼs travel. Release the gate drive as
detailed above first. Lay one section of rack across the drive pinion
parallel to the ground. Allowing for 1-2mm of clearance between
and the drive pinion and the rack to avoid pressure and possible
damage to the gears. Allowance should be made for later adjusted
to the rack, mark the first hole at the end of your rack. Fasten the
rack in place, role the gate forward and fasten the remaining
sections of rack using the same method.
1-2mm clearance
between drive and rack.
Mounting the Motor
Hand tighten one of the nuts provided onto each of
the four posts (tighten to about 15mm from the base
of the plate) then place a washer (provided) onto
each post.
Remove the cover from the motor and fit the motor
onto the threaded posts. Position the motor and
drive pinion approximatly in place (some
adjustments may be required).
Place a washer onto each post then hand tighten
the nuts provided onto the post, some final
adjustments will be required so do not tighten the
nuts yet.
NOTE: Remove any foam packing from the motor
assembly.
Fitting the Magnets
Your MGS gate kit contains two magnets,
marked one and two. These indicate to the
gate motor the gate position it is essential that
they are fitted correctly.

SETUP
Overview
1. Ensure all safety and trigger devices are installed. Any
unused safety inputs MUST BE BRIDGED.
2. Ensure the gate path is clear of obstacles.
3. Check the LEDs are working correctly. 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”.
5. Dip switch 7 determines the direction of opening
(see Dip switch description)
6. Set the force at the potentiometer “FORCE “ to approx
30% lower if the gate is light. Adjust force up or down in
small increments.
7. Switch off control board (cut from current)
8. Set jumper switch to on if installing 771ANZ safety
beams. See page 8.
Programming the travel time
1. With the gate disengaged, roll the gate to its start and
stop limits to ensure the LED change state.
2. Move the gate to about halfway through its travel and
engage the pinion (see page 4).
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.The travel time has now been programmed. The
soft stop (slow run) is programmed automatically approx. 4-5
seconds before the limit switch is reached. This option can
be selected via dip switch (page 11).
NOTE: If the gate closes instead of opening, dip switch
7 must be moved to the other position! Turn the power
off and start again.
Completion of the installation/programming:
Once the travel time is programmed. Test the gate by using
the Remote controls provided with your kit.
1. Start the gate with the remote or an activation button:
ensure the gate opens completely and closes completely.
Note1:
If the gate does not respond check the remotes are
programmed properly and that the PE beams are aligned.
Note2: If the gate reacts to the input closure (terminals
7+10) but fails to operate using the remote control, check
the module is plugged in correctly and that the remotes are
programmed correctly.
2. If the gate does not close completely by itself, some fine
tuning of the force potentiometer may be required.
Make: small adjustments to the force setting, do not simply
turn the trim pot to full force.
3. Now start a second attempt and proceed as above. Close
the gate first before you make any settings.
4. If 771E PE beams are installed on your system you
should adjust the closing time now that all other function
tests are complete.
5. Commission the site by demonstrating the gates
functionality to your client and ensure they are familiar with
the manual release procedure as set out on (page 5).

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).
What happens in case of power failure?
Your Merlin MGS gate opener is equipped with a release system by
means of which the gate can be operated manually in case of power
failure.
Is it possible to open gate 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”)
Troubleshooting and Frequently Asked Questions
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 openerʼs 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 boardʼs self-diagnosis functionality.
The remote controlʼs 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. ANT4X1EML.
The control board does not work any more using
the transmitter, only with the switch and even then
only as long as a button is pressed and kept
pressed.
Open with push-button (1) or CLOSE with pushbutton (2)
1.Dip switch setting not as desired
2.A safety photocell, a contact strip or the
stop disables the control board
3.Only one photocell was connected for
OPEN
1.Correction of the dip switch,
elimination of fault required. If the fault
cannot be repaired, it will be necessary
to “reset” and re-program (see
photocell)
2.At least one photocell must be
connected and activated for CLOSED or
OPEN & CLOSED.
