Please read the following safety precautions carefully
Please read the following safety precautions
carefully
For much protection, it is strongly
recommended to use photo beam sensor
devices, only with a bit extra cost.
While operating the rolling door opener, always
keep the moving door in sight, and ensure that
nobody, no vehicle below the moving door.
Ignorance of this warning, severe personal
injury or equipment damage may happen.
Please do not operate the opener while a kid or
someone standing by the door. During the
process of operating the opener, in the case of
a kid nearby, the kids should be taken after by
his/her supervisor. Ignorance of this warning,
severe personal injury or equipment damage
may happen.
Children are not allowed to operate the door
opener in case of sever personal injury.
Make sure automatic obstacle detection
function performs well. Please test and set this
function according to the instructions strictly,
and conduct a regular test. If needed,
necessary adjustments should be made.
In the case that people, car or other objectives
below the rolling door, please do not pull the
clutch and operate manually.
In the case of installing wall switch or wall
transmitter, the location of wall switch or wall
transmitter should be beyond the reach of
children.
The rolling door must be well balanced. In the
case that sticking or bending, it is required to
ask qualified installation workers to check and
repair. Do not repair the door or the door opener
arbitrarily, since that there is powerful spring
inside the door, which may cause physical
injury and property loss.
Before installation of door opener, please
remove or unlock the rolling door and
mechanical devices.
The power supply for the rolling door
opener must be connected to standard
220V socket by professionals, and with
sound grounding.
The power must be cut off whenever
mending the opener or opening its cover.
The door opener should be mended by
professionals.
Hands and loose clothes are prohibited
approaching the door or door opener no
matter when.
In the case of automatic closing mode, the
photoelectric protection device must be
installed correctly. The photoelectric
protection device must be tested regularly.
While using the automatic closing function,
the above safety code should be obeyed
strictly.
In case that the door can rebound while
encountering obstacles to open mode, it
should be ensured the obstacle reverse
function be adjusted properly during the
installation of door opener. The debugging
of obstacle reverse must be carried out
repeatedly, if necessary, adjustments may
be made.
Make sure that the rolling garage door is
completely open before entering and
exiting.
Make sure the rolling garage door is
completely closed while leaving.
Features
ERDO are endowed with quite a few new
features. The components and materials used in
the control board are of the latest technology and
best quality. Following are the main features:
Easy Operation
Press the buttons of the handheld transmitter of
rolling door opener, the door will open or close
automatically. While the door is closing, simply
press the button, then the door will stop moving
down and open reversely. When opening, simply
press the button, then the door will stop moving.
Also, the above function can be achieved by
wall-mounted transmitter or wall switch (optional)
or the button on the cap of main control board.
Encryption Coding
Every time the remote control transmitter works,
the encryption coding will change once. The
possible password combination can be as much
as 4.29 billion, which enhances security
tremendously and makes “code-pirating”
impossible.
Intelligent Barrier Detection System
While the door is doing a closing cycle and hitting
an obstacle or be restricted in some manner, the
door can reverse automatically. Likewise, while
the door is opening and encountering an
obstacle, the door will close automatically. The
force of resistance should be adjusted via the
potentiometer of the main control board during
the initial installation. The force of resistance
should be checked at least once monthly, more
details please refer to installation instructions.
Security Code Storage of Transmitter
The latest advanced technology is applied in
encryption coding stored in transmitter. Up to 30
different code of transmitter can be stored. To
store any new code, simply press the CODE
button on the opener and press the transmitter
button twice, the transmitter code will be stored
immediately. The code can be deleted at any
time.
Automatic Courtesy Lights
The courtesy light on the Opener turns on
automatically whenever the door is activated to
do an opening or a closing cycle. When the
door stops moving, the courtesy light will stay
on for approximately three minutes then turns
off automatically.
Automatic Closing Mode
The Opener can be programmed to automatic
closing mode. The function of automatic delay
closing can be opted via the jumper on the
opener. I f this mode is selected, a photo beam
sensor must be installed.
Multiple Protection
Overtime protection; Low voltage protection;
Rotating speed fluctuation protection.
Manual Operation
The Opener is equipped with a manual
disengaging system. I f the power to the
Opener is cease for some reason, the door can
be shifted to manual mode by pulling down
string handle, in this situation manual open and
close is allowed. When the power is restored,
pull down the string handle then the opener is
back to the automatic mode.(The above
situation is suitable for single clutch-ERD1007;
if ERD1006—double clutches, pulling down the
red string for manual operation, pulling down
the green one for automatic operation mode).
Soft Start Soft Stop
This function can abate the impact on the door
caused by opening and closing the door
effectively.
Photo Beam Sensor(optional)
The Opener has an input for photo beam
sensor , which is to be connected for extra
safety protection. The photo beam sensor must
be installed if auto closing mode is chosen.

1 Check the door carefully
Before the installation of door opener, please check
the door opener carefully, and ensure the rolling
door is well balanced and in a good condition.
Therefore, the door can move smoothly in the
guide rail and can stay at around 90cm—120cm
above the ground. The force of door lifting or
downing should not over 20kg.
2 Fixing the door weight balancing bars
Move the door manually to half open position, and
place the weight balancing bars equally apart on
the door bottom, then fix them with the fasteners
provided . (see picture 3 ) Check the door again, if
the door moves heavily in the guide rail, it may
require extra tension to be added to the door
springs. In this case , please refer to the door
installation instructions from door manufacturer on
how to adjust the door spring.
3 Door opener on the right or left
