Adjustment Step 1

Adjust the UP and DOWN Limits

Do not make any limit adjustments until the safety reversing sensors are completely installed_

Limit adjustment settings regulate the points at which the door will stop when moving up or down.

The door will stop in the up direction if anything interferes with door travel The door will reverse in

the down direction if anything interferes with the door travel (including binding or unbalanced doors).

To operate the opener, press the Door Control push button,. Run the opener through a complete travel cycle.

•Does the door open and close completely?

•Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (See page 30).

Adjustment procedures are outlined below. Run the opener through a complete travel cycle after each adjustment.

Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.

Read the procedures carefully before proceeding to Adjustment Step 2oUse a screwdriver to make limit adjustments.

Improper adjustment of the travel limits will interfere wlth the proper operation of the safety reverse system. The door might not

reverse properly when required and could seriously injure or kill someone under it. Test

the safety reverse system following all adjustments to the travel limits. See page 30.
