Adjusting the Open and Close Limits
The limit settings control how far the door will open or close. The limits should be set so the door opens just short of any door stops, and closes at the fl oor level. If required, use the following steps to adjust the limits. After beginning to adjust the limits, if no buttons are pressed for one minute, the opener will return to normal operation.
Adjusting the Open Limit
- Use the wall station or a remote control to move the door to the open limit position.
- On the back of the opener, press both the UP and LEARN buttons for three seconds. The green indicator and opener’s light will fl ash twice then stay on.
- Use the UP and DOWN buttons to jog the door at slow speed to fi ne-tune the open limit position.
- When the door is at the proper open limit position, press the LEARN button to store the setting and exit setup. The green indicator and the opener’s light will flash two times
Adjusting the Close Limit
- Use the wall station or a remote control to move the door to the close limit position.
- On the back of the opener, press both the DOWN and LEARN buttons for three seconds. The red indicator and opener’s light will flash twice then stay on
- Use the UP and DOWN buttons to jog the door at slow speed to fine-tune the close limit position.
- When the door is at the proper close limit position, press the LEARN button to store the setting and exit setup. The red indicator and the opener’s light will flash two times.
Adjusting the Force Factor (Installation Option, Normally Not Used)
The opener uses the peak force measured during each of the last four complete cycles plus a “force factor” to calculate the maximum allowed force setting for the current door cycle. If the calculated maximum force setting is exceeded during the current door cycle, the opener reacts to the obstruction. As door hardware conditions change over time with weather and wear, the calculation of the maximum door force setting using the four cycle running average will compensate for the current conditions of the installation
Changing the Force Factor Setting
As an installation option, the opener’s “force factor” can be adjusted to change the amount of pressure exerted on an obstacle before the opener reacts to the obstruction.
- Press both the UP and DOWN buttons for three seconds. The red and green indicators and opener’s light will fl ash twice.
- Use the UP or DOWN buttons to set the force factor. Pressing the UP button increases the force factor, pressing the DOWN button decreases the force factor
- After selecting the force factor, press the LEARN button to store the setting and exit setup. The red and green indicators and the opener’s light will fl ash two times. (If the force factor is not set within one minute, the opener will return to normal operation at its previous force factor setting.)
- After changing the force factor setting, perform the Safety System Reversal Test.
