C-Rail Attachment
Single piece
C-Rails are pre-tensioned during 
manufacturing for transport. Some 
extra tension may be required after 
installation.
If the C-Rail needs to be shortened 
or lenghtened (using the extension 
kit) ensure these modifications are 
made to the drive unit end.
To prevent scratching the unit after 
attaching the C-Rail, place the drive 
unit back in its packing box.

To Increase Force Pressure
a. Hold down the FORCE MARGIN SET 
button.
b.  While holding the FORCE MARGIN SET 
button, press the PLUS (+) button. Each 
press will increases the force margin. 
c. The OPEN LIMIT LED will flash each time 
the PLUS (+) button is pressed to indicate 
an increase in force. 
d.  If the OPEN LIMIT LED flashes 
continuously when the PLUS (+) button 
is being pressed, this indicates that 
the maximum force setting has been 
reached.
e.  Test the force again as per Testing Close 
Cycle and Testing Open Cycle.
To Recall Factory Set Force
a. Holding down the FORCE MARGIN SET 
button and the LIMIT SET button for two 
seconds.
b.  Release both buttons. The default setting 
should now be recalled.

 WARNING!
•  The door may operate unexpectedly, therefore do not allow anything to stay in the path of 
the door.
•  When operating the manual release while the door is open, the door may fall rapidly due 
to weak or broken springs, or due to being improperly balanced. 
•  The drive must not be used with a door incorporating a wicket door, unless the drive cannot 
be operated with the wicket door open. 
•  The drive is intended to be installed at least 2.5m above the floor.
•  Do not disengage the opener to manual operation with children/persons or any objects 
including motor vehicles within the doorway.
•  If the door is closing and is unable to re-open when obstructed, discontinue use. Do not 
use a door with faulty obstruction sensing
•  When using auto close mode, a Photo Electric beam must be fitted correctly and tested 
for operation at regular intervals. Extreme caution is recommended when using auto 
close mode. All safety rules must be followed.
 ELECTROCUTION!
•  Place opener in protected area so that it does not get wet.
•  Do not spray with water .
•  Disconnect the power cord from mains power before making any repairs or removing 
covers. Only experienced service personnel should remove covers from the opener.
•  If the power supply cord is damaged, it must be replaced by an Automatic Technology 
service agent or suitably qualified person.
•  Connect the opener to a properly earthed general purpose 240V mains power outlet 
installed by a qualified electrical contractor.
CAUTION:
Emergency Access •  If garage has no pedestrian entrance door, an emergency access device should be 
installed. This accessory allows manual operation of the garage door from outside in case 
of power failure.
Muscular strain •  Practice correct lifting techniques (carton weighs approx 9kgs)
•  Practice correct lifiting techniques when required to lift the door as per installation instructions.
Fall from ladder •  Ensure ladder is the correct type for job.
•  Ensure ladder is on flat firm ground that will take the weight without the legs sinking.
•  Ensure user has 3 points of contact while on ladder.
Crush injury from unsecured 
door
•  Place a 2 metre exclusion zone around area under the door while it is unsecured.
•  Do not move under a door while it is on the door support (or ladder)
•  Follow the installation instructions
•  Fit door support (or ladder) snugly under door before removing bracket.
•  Ensure door support (or ladder) is on flat ground
Garage Door •  Examine the door installation, in particular cables, springs and mountings for signs of wear, 
damage and imbalance.
•  The garage door must be well balanced. Sticking or binding doors must be repaired by a 
qualified garage door installer prior to installation of the opener.
•  Remove or disengage all garage door locks and mechanisms prior to installation of the 
opener.
Entanglement  •  Never plug in and operate opener prior to installation.
•  Keep hands and loose clothing clear of door and guides at all times.
Entrapment under  
operating door 
•  DO NOT operate the opener unless the garage door is in full view and free from objects 
such as cars and children/people. Make sure that the door has finished moving before 
entering or leaving the garage
•  In order for the opener to sense an object obstructing the door way, some force must be 
exerted on the object. As a result the object, door and/or person may suffer minor damage 
or injury.
•  Ensure the garage door is in good working order by undertaking regular servicing.
•  Install the optional wall transmitter in a location where the garage door is visible, but out 
of the reach of children at a height of at least 1.5m.
•  Photo Electric beams must be installed if the closing force at the bottom edge of the door 
exceeds 400N (40kg)
This automatic garage door opener is designed and tested to offer safe service provided it is 
installed and operated in strict accordance with the following safety rules. Failure to comply with 
the following instructions may result in death, serious personal injury or property damage.

WARNING! Take care when testing or adjusting the 
Safety Obstruction Force. Excessive force may cause 
SERIOUS PERSONAL INJURY and/or PROPERTY 
DAMAGE.
Testing Close Cycle
a.  Press the programmed transmitter to open the door. 
b.  Place a piece of timber approximately 40mm high on the 
floor directly under the door.
c.  Press the programmed transmitter to close door. 
d.  The door should strike the object and re-open.
Testing Open Cycle
a.  Press the transmitter to close the door.
b.  Press again to open the door. 
c.  When the door reaches approximately half way, firmly grab 
the door’s bottom rail - the door should stop. 
d.  If the door does not reverse readily when closing, or stop 
when opening, the force may be excessive and need 
adjusting.
40mm block of wood 
WARNING! If the door fails these tests, put the opener into 
manual mode, only operate the door by hand and call for 
service.
WARNING! Photo electric beams must be installed if the closing 
force at the bottom edge of the door exceeds 400N (40kg) force.
NOTE: Once the travel limits are set and safety obstruction force tested check the chain or belt tension. As per the sticker on the C-rail the chain 
or belt should sag slightly, so there is a 5mm gap between the bottom of the C-rail and the chain or belt.
The tension can be varied by using a spanner to adjust the bolt at the door end of the C-rail.
Be sure not to over-tension the chain or belt as this can cause damage to the C-rail or opener.
Adjusting Safety Obstruction Force
The Safety Obstruction Force is calculated automatically during setup. Adjusting this is normally only necessitated by environmental conditions 
such as windy or dusty areas, and areas with extreme temperature changes.
