Setting the Limits

Travel limits regulate the points at which the door will stop when moving up or down. Follow the steps below to set the limits.

To program the travel limits:

Note: Please ensure door is in open position.

1.Open the light lens. Press and hold the black button (1) until the yellow indicator light (3) starts flashing slowly and then release.

2.Push and hold the black button (1) until the door reaches the desired open position. Adjust the position of the door by using the black (1) and orange (2) buttons. Black moves the door UP, orange moves the door DOWN.

3.Push the programmed remote control (4) or push bar on the door control that was shipped with your opener. This sets the full UP (open) position. The door will travel to the floor and reverse back to the UP (open) position. The opener has learned its travel limits.

Check to be sure the door is high enough for your vehicle. Adjust if necessary.

4.The indicator light (3) will stop flashing when the limits have been learned.

If the door stops or reverses before it reaches the floor repeat steps 1-3 immediately. If this does not set the limits, proceed to #15 of the TROUBLESHOOTING GUIDE and follow the instructions for setting the limits manually.

NOTE: The worklight blinks 11 times whenever the Limits Setting routine fails. If you get this error, proceed to #15 of the TROUBLESHOOTING GUIDE section and follow the instructions for setting the limits manually.

Setting the Force

The force setting button is located behind the light lens of the opener. The force setting regulates the amount of power required to open and close the door.

1.Open the light lens. Locate the orange button (2).

2.Push the orange button (2) twice to enter unit into Force Adjustment Mode. The LED (3) (indicator light) will flash quickly.

3.Push the programmed remote control (4) or push bar on the door control that was shipped with your opener. The door will travel to the DOWN (close) position. Push the remote control

(4) again, the door will travel to the UP (open) position.

The LED (3) (indicator light) will stop flashing when the force has been learned.

The door must travel through a complete cycle, UP and DOWN, in order for the force to be set properly. If the unit cannot open and close your door fully, inspect your door to insure that it is balanced properly and is not sticking or binding.

The force MUST be learned in order to properly complete the setting of the limits.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Test the Safety Reverse System

The safety reverse system test is important. Garage door must reverse on

 

 

 

 

 

 

 

 

 

 

 

 

contact with a 40mm obstacle laid flat on the floor. Failure to properly adjust

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

opener may result in serious personal injury from a closing garage door.

 

 

 

 

 

 

 

 

 

 

 

 

Repeat test once a month and adjust as needed.

 

 

 

 

 

 

 

 

 

 

 

 

Procedure: Place a 40mm obstacle (1) laid flat on the floor under the garage door.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Operate the door in the down direction. The door must reverse on the obstruction.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If the door stops on the obstruction, remove obstruction and repeat Setting the

 

 

 

 

 

 

 

 

 

 

 

 

Limits step 25. Repeat test.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When the door reverses on the 40mm obstacle, remove the obstruction and run

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

the opener through a complete travel cycle. Door must not reverse in closed

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

position. If it does, repeat Setting the Limits and Force steps 25 and 26 and repeat

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

safety reverse test.

In addition to the Safety Reverse test it is recommended that you check your doors

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

lifting strength. To perform this test, place 20kg at the center of the door and ensure

 

 

 

 

 

 

 

 

 

 

 

 

that the door will not move up more than 500mm.
