P EASE START BY READING THESE IMPORTANT SAFETY RU ES • SAVE THESE INSTRUCTIONS
This safety alert symbol means "Caution" - failure to comply with these instructions may result in
personal injury or property damage. 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 comply with
your local building and electrical
installation codes.
Power cables must only be connected to a
properly earthed supply.
Where a risk of entrapment exists between
a moving wing and walls, safety edges or
IR-sensors must be installed.
Before servicing, removing covers or
repairing any gate motor, disconnect
electric power.
An isolation switch must be installed if your
gate motors or control boards are hard
wired.
Be careful when using tools and small
parts to install or repair gates.
Do not wear rings, watches or loose fitting
clothing.
These instructions should be kept in a safe
place and provided to any electrical
contractors or gate installers servicing
your unit.
Please remove any locks fitted to the gate in
order to prevent damage to the gate.
Prior to installation, ensure that the gate
runs smoothly. If gate sticks or jams it must
be repaired immediately. This must be carried
out by a Gate Technician. Do not attempt to
repair the gate/s yourself.
Gates can be dangerous! Please ensure that
all accessories and remote control devices
are kept away from children. Never allow
children to play near an operational gate.
After installation is complete a final test of
A functions and SAFETY systems must
be carried out.
Where safety devices are installed, it is
essential that these devices are functioning
before leaving the site.
DO NOT APP Y POWER until all safety
devices are functioning properly.
Where a secondary gate (wicket door) or
other access is incorporated in the gateʼs
construction a safety switch must be
installed.

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: nsure 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: xtreme 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 P 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)

• Base plate
• Accessories bag

Carton contents

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.
nsure 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.

Manual release
In the case of a power failure or to move the gate freely
during installation the drive pinion must be disengaged.
To release the drive pinion.
• Turn the key 180 degrees to unlock
the release mechanism
• Turn the release mechanism 270
degrees to the right to release the
pinion.
NOTE: The gate should move freely once the drive
pinion has been released.

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.
NOT : Remove any foam packing from the motor
assembly.
Fittin the Ma nets
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.
Magnets must be installed between
10-15mm from the limit switch
(see page 6).

Installing the magnet bracket Steel Rack.
Identify your start and stop limit. Using the magnet
bracket mark two holes as shown above. Drill two
holes into the rack then install the spacers provided
into the back tabs using the raised pins to position.
Once the spacers are in place, fit the bracket over
the rack and tighten the screws. Install the start and
stop limit magnets as outlined above using the bolt
and nylex nut provided.
Installing the magnet and bracket for nylon
rack.
Identify your start and stop limit. Fit the bracket over the
rack and tighten the screws. Install the start and stop
magnets as outlined above using the bolt and nylex nut
provided.
Installing the imit Magnets
Caution: The magnet limit switches are polarity sensitive and must be installed in the positions as marked
above, failure to do so will cause your motor to malfunction.
NOTE: If your gate opens to the EFT Magnet 2 should be at the open limit, for a RIGHT hand opening gate
Magnet 1 must be position as the open limit as illustrated above.
Caution: You must have rack installed along the entire length of its travel including the start and stop limits.
