2. Obstruction Force Adjustment (Menu option 2 on display)
CAUTION: the obstruction force adjustment is set automatically during programming.
Normally, no adjustment is necessary.
The factory-set forces (value 3) are designed to provide a smooth operation of the opener
with standard garage doors; the factory setting forces should, in principle, be sufficient to
fully open and close the garage door.
The factory setting of the opener complies with the legal or relevant standards (such as the
EN 13241-1, EN 12453, EN 60335-2-95) established requirements for operational forces,
and thus the maximum allowable power limits.
The operating force of the opener may be increased or decreased (values 1 - 5), if
necessary, by the following procedure below.
NOTE
This must be done when, for example, the end-stop point of the garage door during the
opening or closing phase via the factory setting (value 3) is not met; the setting for the force
output can be increased (as described below) so that the the respective end-point is
reached.
In addition, during the operational period of the garage door, the operational optimality may
deteriorate (e.g. slackening of tension springs). Therefore, for safety reasons, adjusting
force of the opener on an unsound garage door could result in a malfunctioning door, thus
increasing the risk of personal injury or property damage -- this risk is especially increased
when activating the manual release of the garage door from the opener.
DANGER
Deviating/Increasing the factory force setting (value 3) can lead to serious personal injury,
up to the danger of life as well as property damage! Altering the factory force setting
increases the pressure exerted by the opener when opening and closing the garage door,
thus increasing the force that the garage door exerts in each respective phase. When
changing or differing from the factory settings, the risk of severe injury to persons up to the
danger of life as well as the risk of damage to property is increased - for example, by
pinching or squeezing persons or things near the garage door. Differing from the factory
settings, increasing the power setting to exceed the aforementioned maximum allowable
limit can cause power limitations. Therefore:
NOTE:
Adjusting the factory force setting (value 3) to an alternate value (value 1-5 ) must be
ensured to be compliant with the legal requirements and relevant standards of force
limitations by a competent person. Inspections must be performed and documented
to the described risk of injury and exclude life and property.
a) Press and hold the SET Button until "1" appears on the display,
then release the button.
b) Press the UP button until "2" shows on the display.
c) Press SET to enter this setting sub-menu. You're now in the force
setting adjustment mode. A "3" will be shown on the display. Press
the UP button to increase the force setting or the DOWN button to
decrease the force setting. The maximum force is 5 and the
minimum is 1.
d) Press SET to confirm your selection. The display will return to "I I".
NOTE: The factory force setting is 3.
