11 Aligning the Infrared Safety Beam
The safety beam has two components, a sender and a receiver. The sender produces a narrow infrared beam that
travels across the bottom of the door opening to the infrared receiver. If an object blocks the infrared beam while the
door is closing, the door will stop, then reverse and fully open (the operator's light will flash three times).
As a safety feature, the operator will ignore signals from all remote controls if the door is open and the
infrared safety beam is blocked or out of alignment. In this case, the door can be forced closed by pressing
and holding the wall station's up/down arrow pushbutton (be sure the door area is in clear view).
WARNING WARNING
With the door closed, disengage the trolley Serious injury or death from a closing garage
from the chain during these alignment tests by door may result because of failure to test and
pulling the red release handle. adjust safety reverse system. Repeat this test
monthly and adjust as needed.
Safety Beam Test
1 Check that the operator has power. The green lights on
the sender and receiver should be lit.

12 Remote Controls
The operator is supplied with a three-button remote control (the second and third buttons can be used to control an
additional operator or gate if it contains a Linear MegaCode™ receiver). Additional single and multi-button remote
controls can be purchased. An unlimited number of remote controls can be used with this operator. The short white
wire on the back of the operator serves as an antenna for the remote controls. Do not cut off the white wire or the
remote controls will not operate well.
WARNING
PREPARING TO ADD A REMOTE
Children operating or playing with a garage door
operator can injure themselves or others. The
garage door could cause serious injury or death.
Do not allow children to operate the remote
control(s) or the wall station. A moving garage
door could injure or kill someone under it. Activate
the operator only when the door is clearly visible,

13 Adjusting the Open and Close Limits
CHECKING WHERE THE DOOR STOPS
The limit adjustments that control how far the door will
open or close are located on the side of the operator. The
limits should be adjusted so the door opens just short of
any door stops, and closes right at the floor level. Each
full turn of a limit adjustment equals about 2-½" of door
travel.
CAUTION
Set the open and close limits carefully. Setting
the limits beyond the distance that the door can
travel could cause damage to the door, the door

operator. The door force adjustments must be properly
set at all times. The CLOSE FORCE adjustment controls
how much force is required to cause the door to reverse
direction if an obstruction is encountered during closing.
The OPEN FORCE adjustment controls how much
force is required to stop the door if an obstruction is
encountered during opening.
WARNING
Too much door force will interfere with the

Weather conditions may affect the door operation which could require some re-setting of the operator's adjustments.
Doors may swell and become heavier during wet periods, door hinges and rollers might bind during cold periods. To
WARNING
insure safe operation of the door, perform the following tests, including any additional test steps described.
Every Month
1 With the door closed, pull the red release handle to
disconnect the operator from the door.
2 From outside the garage, slowly open the door
manually all the way, and then close it all the way.
Notice if there is any binding, sticking or rubbing. The
door should move smoothly in both directions.
3 Raise the garage door about halfway up. Carefully
release the door and see if the door balances. It should
stay in place. Close the door.
� N OTE: If the garage door is unbalanced or the
door travel isn't smooth, have a qualified garage door
professional adjust or repair the door.
4 To reconnect the operator, flip the release lever
up. Raise the door manually until the operator
reconnects.
5 Perform the Safety Beam Test (Section 11).
6 Perform the Safety Reversal System Test as described
in Steps 4-6 in Section 14.
After Servicing the Operator
1 Perform the Safety Beam Test (Section 11).
