Adjusting the Limit Switch
Note: Before adjusting the limit switch,
refer to the chapter of “Install the Opener
on the Gate”, and make sure that the rod
is fully retracted when the gate is in the
fully open position (for Pull-to-Open
installation), or in the fully closed position
(for Push-to-Open installation). Make sure
that currently the rod is fully retracted.
Note: The position of Limit Switch A was fixed in factory, do not adjust it again.
1 For Pull-to-Open Installation, adjust the limit switch B to determine the closed position:
Turn on power to operate the gate opener, then the arm extends to close the gate.
If the arm closes over the desired closed position, press the remote control to stop the opener. Use a screwdriver to
loosen the screw of the limit B, slightly slide the limit switch B
inwards.
If the arm closes halfway and fails to get to the desired closed position, slightly slide the limit switch B
outwards.
Please
repeat
the above steps, until the arm could arrive and automatically stop at the desired close position. Then
tighten the screw firmly.
Limit setting is finished now.
2 For Push-to-Open Installation, adjust the limit switch B to determine the open position:
Turn on power to operate the gate opener, then the arm extends to open the gate.
If the arm opens over the desired open position, press the remote control to stop the opener. Use a screwdriver to
loosen the screw of the limit B, slightly slide the limit switch B
inwards.
If the arm opens halfway and fails to get to the desired open position, slightly slide the limit switch B
outwards.
Please
repeat
the above steps, until the arm could arrive and automatically stop at the desired open position. Then
tighten the screw firmly.
Limit setting is finished now.
