12. Auto-reverse function
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 and self learning. 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 Over Current 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. Start with just
above the minimum value, and tune it to use the minimum setting for which the gate
will function.
WARNING: Do not attempt to tune the gate by placing your hand, arm or other
body part in the path of the gate. This could result in serious injury. Also placing a
heavy immovable object in the path to test with could cause damage to the gate
opener motors. Instead, place a light object in the path, preferably something like a
chair or trash can which will be pushed out of the way if the setting is still too high
without causing damage to the gate motors. Note, this auto‐reverse function should
be regularly inspected and adjusted if necessary. Once this step is complete, replace
the cover and install the rubber caps over the screws.
OVER CURRENT SENSITIVITY:
The limit of Over‐Current can be adjusted from Min
3.5Amp to Max 7 Amp.
CLOSE DELAY: The time for the SM2 (slave leaf) start
delay for gate closing can be adjusted from Min 0 second
to Max 8 second.
