CAUTION: If your 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.
Automatic Technology strongly recommends Safety Beams are installed with the automatic opener
ensuring additional safety and peace of mind.
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.
DO NOT operate the opener when children/people are near the door. Children must be
supervised at all times when the Ero™ is in use. Serious personal injury and/or property
damage can result from failure to follow this warning.
DO NOT allow children to operate the Ero™. Serious personal injury and/or property
damage can result from failure to follow this warning.
Regularly check to make sure that the Safety Obstruction Force is working
correctly, and is tested and set as per page 20 of this manual. Failure to follow
these instructions could result in serious personal injury and/or property
damage. This test must be repeated at regular intervals and the necessary
adjustments made as required.
A Safety Beam must be used if the closing force as measured on the
bottom of the door is more than 400N (40kg).
DO NOT disengage the door opener to manual operation with
children/people or any other objects including motor vehicles
within the doorway while in the open position.
The door opener is not intended for use by young children
or infirm persons without adequate supervision. Children
should be supervised to ensure that they do not play with
the remote transmitters or the opener.
Keep hands and loose clothing clear of the door and
door opener at all times.
WARNING: It is vital for the safety of persons to follow all
instructions. Failure to comply with the following Safety
instructions may result in serious personal injury and/or
property damage.
Important Safety Instructions

Owner Installation Instructions GDO-11v2 Ero®5
The unit should be installed so that it is protected from the elements. It should not be exposed to water or rain.
It is not to be immersed in water or sprayed directly by a hose or other device.
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.
Frequently examine the installation, in particular cables, springs and mountings for signs of wear, damage
or imbalance. DO NOT use if repair or adjustment is needed since a fault in the installation or an
incorrectly balanced door may cause injury. DO NOT attempt to repair the door yourself as hardware
is under extreme tension.
Remove or disengage all garage door locks and mechanisms prior to installation of the opener.
Connect the opener to a properly earthed general purpose 240V mains power outlet installed
by a qualified electrical contractor.
Disconnect the power cord from mains power before making any repairs or removing
covers. Only experienced service personnel should remove covers from the opener.
In order for the Ero™ 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
damage or injury.
If the power supply cord is damaged, it must be replaced by an Automatic
Technology service agent or suitably qualified person.
Make sure that the door is fully open before driving in or out of the garage
and fully closed before leaving the driveway.
Make sure that remote controls are kept out of reach of children.
Install the (optional) wall switch or (optional) wall mounted
transmitter in a location where the garage door is visible, but
out of the reach of children at a height of at least 1.8 metres
from the floor.

Operation
To open or close the door simply press a button on a TrioCode™ handheld
transmitter, or optional wall switch for two seconds. During open and close cycles
the door can be stopped by pressing the button again. The next actuation will
move the door in the opposite direction.
TrioCode™ Code Hopping Technology
Every time a TrioCode™ transmitter is used a new security code is randomly
generated from over 4.29 billion possibilities. This greatly enhances the security
of the system and makes “code grabbing” a thing of the past
These transmitters also overcome interference issues by simultaneously sending a
signal over three different frequencies. Even if two of the three signals are jammed,
the system will still work.
S-ALPS (Semi Automatic Limits Positioning System)
The S-ALPS system does away with manual adjustment of the door’s limits position
using mechanical parts, such as cams and microswitches. During installation the
handheld transmitter can be programmed to set the limits positions.
ISS (Intelligent Safety Obstruction System)
While the door is performing a close cycle, should it hit an obstacle or be restricted in some
manner, it will automatically reverse. The amount of force the door should encounter before
reversing is automatically adjusted by the doors control system during the initial installation of the
automatic door opener. The door will also stop if restricted whilst opening. The Safety Obstruction
Force should be checked monthly.
Auto courtesy light
The courtesy light comes on automatically for three minutes whenever the door is activated. The light can also
be operated independently of the door by coding a dedicated button on a transmitter.

WARNING: The opener must be securely
fastened to structural supports, otherwise opener
failure may ensue causing serious personal injury
and/or property damage.
Step 4 - Determine Bracket Position
Open the door and find the highest point of travel of
the top door panel.
Using a level, transfer this height to the wall above
the door (Fig. 16) and mark a line 60mm above it.
Determine the centre point on the wall above and on
top of the door. Draw two lines extending 21.5mm
from each side of the centre point. (Fig. 17)
Step 5 - Mounting The Wall Bracket
Centre the bracket over the intersection of these two
lines. Mark centres for at least two holes (Fig. 17)
and ensure it is into a solid mounting point.
Drill holes into the wall with an appropriate bit.
Secure to the wall using:
IF CONCRETE OR BRICK - 8mm (5/6”) loxins/dynabolts.
IF TIMBER - wood screw #20 or similar (min. 50mm).
WARNING: Make sure concrete, brick wall or
timber lintels are solid and sound so as to form a
secure mounting platform.

Stop the door when it is at its highest point of travel.
Allow 25mm additional height for clearance between
the door and the track (Fig. 22).
Support the C-Rail in this position and close the
door.
The height determined in Step 10 (b) will be the
height at which to mount the wall bracket.
Centre the bracket along the line determined in Step
8.
Using the bracket as a template, mark a minimum of
two holes and drill with appropriate size bit. For a
more secure fitting, the wall bracket can be anchored
using more than two holes.
Secure the bracket to the wall using:
IF CONCRETE OR BRICK - 8mm (5/6”) loxins/dynabolts.
IF TIMBER - wood screw #20 or similar (min. 50mm)
Attach the bracket and C-Rail with supplied pins (Fig. 18).
WARNING: Make sure concrete, brick wall or

Step 12 - Mounting Door Bracket
The door bracket comes in two parts. The bottom plate
with two mounting holes is used on its own for one piece
doors. For sectional doors, the top plate is placed over
the bottom plate and is fixed with four (4) screws (Fig.
24).
Mount the door bracket, or bracket assembly,
on the door’s centre line one-third down the top
panel (Fig. 24) using M6 or equivalent screws (not
supplied),
STEEL DOORS ONLY: Bracket can be welded in
place.
WARNING: Door damage may occur if the bracket
is installed on a panel with insufficient strength.
The opener’s warranty does not cover damage
caused to the door and/or door panels. If in doubt
about the door’s strength, reinforcement may be
added to the door’s frame where necessary.
Step 13 - Attaching the Arms
For Sectional And One Piece Doors With
Track:
Assemble the bent arm (connecting to the door)
to the right side of the straight arm (connecting
to the shuttle) with bolts and nuts supplied in the
accessory pack (Fig. 25). Always use both bent and
straight arms.
Connect the assembled arm to the bracket and the
disengaged trolley with clevis and snap pins. The
angle “A” must be more than 10° (Fig. 26).
WARNING: Connecting the bent arm the other
way around may damage the door. The straight
arm should not protrude beyond the heel of the
bent arm.
For One Piece Doors Without Track
Assemble the bent and straight arms as shown in
Fig. 27 with bolts and nuts supplied in the accessory
pack. Always use both the bent and straight arms.
Connect the assembled arm to the bracket and the
disengaged trolley with clevis and snap pins.
If installing on a door with a bad wave action,
lengthening the arm will assist in reducing this
effect.
IMPORTANT NOTE: Adjust the length of the
cord so that its toggle is no more than 1.8m from
the ground.

Safety Obstruction Force Test
WARNING! Take care when testing or adjusting
the Safety Obstruction Force. Excessive force
may cause SERIOUS PERSONAL INJURY and/or
PROPERTY DAMAGE
WARNING! FOR ADDITIONAL ENTRAPMENT
protection we STRONGLY recommend the fitting
of a Safety Beam (SB). In most countries Safety
Beams are mandatory on all garage doors fitted
with automatic openers. For a small additional
outlay Automatic Technology recommends that
Safety Beam be installed with the automatic
opener ensuring additional safety and peace of
mind.
WARNING: Safety Beam must be installed if the
closing force at the bottom edge of the door
exceeds 400N (40kg force)
Step 16.1 - Testing Close Cycle
Press the OPERATE button to open the door (Fig.
33).
Place a piece of timber approximately 40mm high
on the floor directly under the door (Fig. 34).
Press the OPERATE button to close door. The door
should strike the object and start to re-open.
Step 16.2 - Testing Open Cycle
Press the OPERATE button to close the door (Fig.
33).
Press again to open the door. When the door
reaches the half open point, grab the bottom rail of
the door firmly and the door should stop.
If the door does not reverse readily when closing,
or stop when opening, the force may be excessive
and need adjusting, refer below.
DANGER! If the door fails these tests, put the
opener into manual mode, only operate the door
by hand and call for service.
