Important Safety information 

Sliding Gate Motor - Model 550 AC Sliding

This item must be installed by a qualified electrician

All safety instructions and insallation methods should be read and completely 

understood by the installer and the owner prior to the installation of the gate 

opener system.  This product is designed and manufactured for the use indicated in 

this document.  Remember that all automatic gates are intended for vehicular gates 

only.  A separate gate or entrance must be installed for pedestrian use.  Any other use, 

not expressly indicated may damage the product or be a source of danger.  Do not use 

it on large sized gates that have a steep incline.  Wrong selection of motor will result in 

unreliable operation.

Owner should observe the following:

1. Do not cross the gate while it is operating

2. Keep children away from the gate and the remote control

3. Do no adjust the setting of the control panel unless you understand what you are

doing

4. Learn the use of the the emergency override key.  This is crucial in the event that

the system does not work.

Installer should observe the following:

1. Make sure the gate weight does not exceed the maximum weight specified

2. The gate design must be suitable for the installation of the gate opener system

3. Ensure that the gate is installed on flat,level ground and can move and slide freely

in both directions along the entire gate length

4. Gate opener must be installed in the area where it is not easily damaged

5. Do not change with parts or components not supplied by the manufacturer

6. Make sure all wiring works are correct in accordance with electrical bylaws and in

good condition before supplying the mains power to the control panel

7. Turn OFF the power when doing any maintenance

8. Ensure the control panel box is free from water leakage and insects to avoid short

circuiting of the control panel and voiding warranty

9. Never supply mains power directly to the DC motor if cover is damaged

10. Do not install the operating system if in doubt.  Contact the manufacturer or your

local agent

Install “Physical Gate Stops

Physical gate stops MUST be installed at each end of your gate.  If the 

magnetic switch on the motor fails to stop the gate cycle, the gate stops will 

prevent the gate from falling off the guide rollers and causing possible injury or 

damage.

Installing Motor

Preparation of the concrete ground surface (base) for motor mounting

Make sure that the ground surface for the motor installation is solid and level.  

A good base is paramount to the proper operation of the gate opener 

system.  If installing cables, place these 300mm from your wall/post and 

approx. 220mm in from the corner of the wall/post.  The motor mounting plate 

is 170mm deep x 270mm wide.  Position the motor mounting plate (

side nearest to the gate) approx. 150-160mm from the wall/post and approx. 

50mm in from the post driveway corner point.

Top View Base Footprint

Cables from the control panel to the motor can be 

per-embedded 

in the base 

should concealed wiring be preferred.  Check with you

r

 electrician.  You may 

have to space the bottom of the base plate with spacers to gain some height 

to run wires and cables.  Again check with your electrician.

Prepare for motor cable.  Optional 

devices

 such as wired keypad, photo 

beams etc. use telecom cable, cat-5 or cat-6

NOTE:  You may need to raise the motor to allow the gear rack to fasten 

properly to your gate bottom rail, so check this first by placing a piece of gear 

rack on top of the motors cog alongside the gate.  

Open/close the gate to ensure no fasteners are obstructing the rack.

There are 3 typical ways to fasten the motor to your concrete.

Option 1: If your gate is manufactured with 100 x 50mm rectangular bottom 

rail such as the BMGI low profile model and sits about 40mm off the ground 

with the wheels, you can bolt the motor directly to the concrete.

Hint: Option 2 and 3 are good for raising the motor to allow cables to be 

installed freely under the motor so you do not need to be too accurate with 

your cable location.

Option 2: If your gate is fitted with the standard wheel that raises the gate to 

approx. 50mm from the ground you can use high mounting blocks to lift the 

motor.  Position these spacers under the left and right sides of the motor and 

fasten to concrete.

Option 3: new concrete pad.  If your gate is above 50mm off the ground you 

can use the mounting plate supplied with the motor and the 4 threaded rods, 

1 in each corner to act as pylons.  The rods can be pressed into your concrete 

pad.  You can now line up the mounting plate.  Once the concrete pad has 

dried, you can now assemble, starting with the motor, washers and fasten 

together with 4 more nuts.

Installing the gear rack to the gate:

For your gate to function smoothly you will need to install the gear rack 

correctly.  The outcome is to have a 2mm gap between your 

gear wheel

 and 

the valley of the gear rack throughout the length of the gate.  Temporarily 

raise the motor by another 2mm using bolt-washer spacers under the motor 

mounting bolts.

Release the auto gate to emergency release so that the gear wheel rotates 

freely for the alignment and installation of the gear-rack.  (see picture below)

Starting with your gate in the open position, align your first section of racking to 

sit flush with the start of your gate.  (See picture below)

Emergency Release

Rack installation start

Rest the first gear-rack on the gear wheel, ensure that the gear rack is level 

and secure the gear-rack onto the gate using the fastenings provided.  Move 

the gate 1m and repeat as above until all gear-rack has been installed.  Do 

not fasten where 

w

heels may be contacted as this will increase gate moving 

resistance dramatically.

We strongly recommend you leave your gear rack over hanging (approx. 

100mm) until after you have fitted your “magnet brackets” and only then cut off 

any extra with a steel hacksaw.  The gear rack has a steel rod inserted in the 

nylon casting for strength.

Remove the washer/spacer from the motor and the gap of 2mm between the 

gear wheel and the gear-rack is automatically achieved.  Check to ensure 

consistent meshing between the gear-rack with the gear wheel over the entire 

length of the gate.  Loosen the scre

w

 on the gear-rack to adjust the position of 

the gear rack if necessary.

2mm gap

Important Note: Gear wheel and gear rackings life depends almost 

entirely on their correct meshsing

Install “Magnetic Brackets”

One magnet bracket MUST be installed at each end of your gate, attached to 

your rack.  Supplied is a high bracket and a low bracket, when installed they 

are designed to trigger the internal magnetic limit switch.  This will stop the 

gate cycle BEFORE making contact with the physical gate stops.
The best way to install the ‘magnetic brackets’ is to close the gate to hit the 

stop, slide back open 50mm, now slide the 

LOW

 magnet bracket along the 

racking 

until

 you see 

‘L

’ 

light up on the main control board, then adjust 

magnet on bracket and secure.  To install 

HIGH

 magnet, open gate full and 

pull back 50mm, now slide the 

HIGH 

magnet bracket along the racking till 

you see 

‘L

7

’ 

light up on the main control board, then adjust magnet on 

bracket and secure.

Check that both fully open and fully closed ‘magnetic brackets’ are in place on 

the gear rack and are functioning correctly.  Check both fully open and fully 

closed physical stops are securely in place.
