4.2. Safety Obstruction Force Adjustment
Dual Safety Obstruction Force Adjustment modes ensure that the XTrac can be
optimized to suit virtually any sectional or tip-up type garage door
Adaptive Mode – constantly monitors incremental drive force value changes that
occur due to seasonal conditions and / or garage door aging. Adaptive Mode
compensates for these variables by automatically adjusting Safety Obstruction
Force values during every complete cycle, resulting in enhanced safety and
minimized chances of garage door ghosting*.(Refer Section.4.2.1 for set-up
details)
Ghosting is defined as a Safety Stop or Safety Reverse without the garage door actually encountering an
obstruction
Manual Mode – features conventional one time Safety Obstruction Force value
adjustment and is more suited for use on badly worn or improperly balanced
garage doors. (Refer Section.4.2.2 for set-up details)
4.2.1 Adaptive (A) Mode
Enabling
If Manual Mode is your desired selection then skip to Section.4.2.2
If Adaptive Mode is already enabled then skip to the next section titled
“Functionality”
To enable Adaptive Mode carry out the following procedure;
I. switch off power at power supply.
II. remove the Courtesy Lamp and Control Box Covers to expose the
Control Board (Refer Section.5.6 for removal and replacement details).
III. select Dipswitch No.1 to the “ON” position (Figure.16).
IV. replace the Control Box and Lamp Covers.
V. switch power on at power supply.
Functionality
In order to learn the required run time and drive force values the XTrac
will be required to complete five (manually activated) uninterrupted open
and close cycles.(commencing from the Close Limit Point)
During the course of the cycles the LED Indicator will quick flash and the
operating parameters will be learned in the following order;
I. Open Stroke 1 – Alignment stroke.
II. Close Stroke 1 – Learn run time between Open Limit
Point and Close Limit Point (during Close Cycle 1 the XTrac will not
Slow Stop).
III.Open Stroke 2 – Learn run time between Close Limit Point and Open
Limit Point (during Open Cycle 1 the XTrac will not Slow Stop)
IV. Close Stroke 2 – Learn Drive Force Values between Open Limit Point
and Close Limit Point.
V. Open Stroke 3 – Learn Drive Force Values between Close Limit Point
and Open Limit Point.
Once Learning has been successfully completed, the LED Indicator will
commence to slow flash
