1997 last week, the family clinic outlined procedures for installing the garage door opener.
The first part of the program consists of assembling the drive rails and power units and then installing them in place.
The next step is to connect the drive mechanism to the door.
The connection between the two is the door arm;
It connects the traveler on the drive track to the bracket that is bolted to the door.
First connect the door bracket to the door with the transport Bolt.
However, make sure the door is solid.
Fiberglass or thin doors-
When the opener applies force to the door, the meter metal may be bent or damaged.
The light door should be reinforced with a bracket (
Available at garage door dealer)
Before connecting the door bracket.
Install the door bracket in the center (
Between left and right)
As high as possible on the door.
Keep the bracket in place so you can mark the position of the mounting hole with a pencil.
Remove the bracket and drill holes from the inside.
Insert bolts from the outside.
Install washers, lock washers and nuts on the stand.
Tighten the nut with a wrench.
Then assemble the door arm.
This is usually made of two pieces of steel, one straight and the other straight.
Must be fixed together with bolts.
Two pieces have a series of holes at each end.
These holes allow you to adjust the length of the arm so that it can fit right between the door and the drive track.
Assemble the arm and then connect one end to the traveler and the other to the door stand.
Advertising most door openers have adjustable limit switches on drive tracks.
They control the distance up and down the door.
Position the forward switch so that it is slightly behind the front of the traveler.
Set the rear limit switch to about 6 inch in front of the power unit.
This initial position is only temporary and may need to be adjusted when you test the door.
Advertising many modern door openers have an electric eye device that projects a beam between the sender and the receiver module.
If the beam breaks, the unit will automatically cut off the power supply and stop the movement of the door.
This is an important safety feature that prevents accidental injuries if a child walks under the door when it is closed.
To install the electric eye unit, place the sender and receiver modules on either side of the door about 6 inch from the floor.
They are mounted on the door frame with special brackets.
Run the wire connection from the sender to the receiver and return to the power unit.
Nail the wire to the wooden frame around the door.
Make sure the wire is only a few inches away from the rail mechanism of the door and be careful that the DingTalk will not pierce or cut off the insulation around the wire.
Place the control switch on a nearby wall and connect the wire to the power unit.

Now is the time to connect the power unit to a nearby circuit.
If the socket is at your fingertips, you can plug it in. (
However, keep in mind that whenever you adjust any part of the opener mechanism, disconnect the power supply. )
Some codes require that the garage door opener be connected directly to the circuit.
This is a professional electrician job.
Hook with power-
You can test the opener when you are done.
Adjust the clutch mechanism first.
The clutch provides mechanical power to the drive mechanism so that the door can be opened and closed.
Ideally, there should be enough power to move the door.
Too much power will make the door difficult or impossible to reverse.
A fairly common clutch mechanism has a adjusting knob with a locking screw in the center.
Loosen the lock screw with a screwdriver and turn the knob to adjust the clutch.
Tighten the locking screw to keep the adjustment fixed.
Not all clutch controls are adjusted in this way, and the controls can change with different models.
Be sure to read the manual for how to adjust the clutch on the opener.
Turn on the power and close the door.
If it doesn\'t turn off all the way, please move the front limit switch slightly forward on the drive track.
If the door hits the floor and reverses, gently push the limit switch.
Start the power switch and raise the door.
If it is not fully turned on, please push the rear limit switch further back.
However, if the switch is too far away, the door may hit the power unit.
Once the door is open and closed properly, you can test the auto-reverse capability and the electric eye.
The test is simple.
To test the reverse, place a block of 2 by 4 on the floor and close the door.
When closing the door in contact with the block, it should stop and reverse.
If not, move the front limit switch forward about 1 out of 1/16 and repeat the test.
Continue the process until the door is reversed.
When the door is closed, test the electric eye by blocking the beam between the modules.
The door should stop and reverse;
If not, check all electrical connections.
The installation is now complete, but it is important to ensure that the door and all hardware are lubricated and checked for wear and tear on a regular basis.
In addition, reverse and electric eye tests should be carried out on a monthly basis.
