K207A Swing Gate Opener User’s Manual
(4) Auto-reverse function
Turning the auto-reverse safety function: Rotating the ‘FORCE ADJ’ (see Fig.14 No.4 and No.5) with
a screwdriver, No.4 force adjustor can be used to adjust No.1 gate-leaf which has lock, No.5 force
adjustor can be used to adjust No.2 gate-leaf.
It is very important that you tune the safety reverse function on your gate opener. Power the control
box if it is not already and verify that you have completed the remote programming exercise. When
properly adjusted, the gate should close and stop when it hits the stop block without overly forcing the
gate, and reverse if it strikes an object before it reaches its stop. An alarm should sound if it activates
the auto reverse. Use a screw driver to rotate the Force Adj. knob. Rotating clockwise will increase
the resistance needed to trip the safety reverse function. Rotating counter-clockwise will decrease
the resistance. If the gate does not move when activated, or auto reverses without striking an obstacle,
then the resistance setting may be too little. If the gate does not stop when an obstruction is placed in
its path, then the setting may be too high.
(5) Auto-close function
Turn on the fourth dip-switch (See Fig.14 No.13) to ON position, the gates will stay open for 30
±
3
seconds before automatically closing. Factory preset: the fourth dip-switch is in the OFF position, i.e.
the auto-close function is shut off. An Infrared device is required to be installed for safety if the
auto-close feature is enabled.
(6) Safe guard (Infrared device)
If infrared beam is broken during closing, the gates will reverse and open immediately.
During opening, the beeper will ring. The control box is not factory equipped with an infrared device.
