Retainer – Closed and Opened Positions
Close the gate section to its fully closed position; fix the retainer according to the position of the gate
section. NOTE: Each section is completed separately. See Fig. 3.

K207A Swing Gate Opener User’s Manual
If the maximum angle for installing is 105°, the retainer should be installed on the ground at approx.
100°. If the installing angle is 90°, the retainer should be installed at 90°. See Fig. 3.
Electric Lock
If the gate section is >5 feet (1.5 meters), it is recommended that you install the electric lock. Weld
the steel plate of the lock to the gate, and then fix the lock. See Fig. 11 to determine the height of the
plate.

Base plate
To install the base plate of the lock, fix the plate to the ground with 3 screws and make sure that the
lock pin can fit tightly in the hole in the plate.
Adjustment
The pair of gate sections will not start simultaneously. The gate section with the lock will start to
open earlier than the other gate section, so that both sections can be locked properly. A plate or tab

K207A Swing Gate Opener User’s Manual
can be welded on the gate section with the lock so that when it closes, it will trap the gate section
without the lock between itself and the center stop block, thus locking both gate sections.
Mechanical Maintenance
zCheck the screw lubricant and add #1 grease regularly to both gate actuators.
zRegularly verify that the gate swings freely and add grease regularly.
zKeep opener clean at all times.
Electrical and Control Box Installation
1. Installation
(1) Install the cable
zIn order to protect the wires, between the gate opener and the control box, armored cable,
galvanized cable or PVC pipe must be set into the concrete when it is poured. Wires within the
cable shall be located or protected so that no damage can result from contact with any rough or
sharp part. The diameter of the cable should be more than 20mm, the wire size inside the cable
should be more than 1.0mm2.
(2) Install the control box
zThe control box circuit should be equipped with single-phase breaker (10A).
zMake sure that power is OFF before making any electrical connections.
zOpen the cover of the control box, remove the control board, and fix the control box on the wall.
See Fig. 12
zPerform the wiring and replace the cover. (See table 1 and Fig.14)
Note: (1) we regard the gate with the electrical lock as No.1 gate, the other gate as No.2 gate. (2) If
you want to use auto-close function, the gate opener must be equipped with the infrared device.

(3)Install the External Keypad/Button Switch
The K207A is equipped with an interface for an external button switch or keypad. To install the
keypad attach two wires of your keypad to the O/S/C terminal. The keypad will function in single
channel mode. For three-button switch installation, use the terminals for multi-channel mode.
Three-button mode: The port ‘GND’ is the common port, the port ‘OP’ is used to open the gate, ‘CL’
is used to close the gate, and ‘ST’ is used to stop the gate. Single-button mode: connect two wires
of button switch to ‘O/S/C’ (see Fig.14 terminal X7 No.15) of control board.
(4) Safe guard (Infrared device)
If the 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.
Connect signal wire of infrared device to ‘IR’ (see Fig. 14 terminal X6, No.14), connect common wire
(i.e. ‘power supply –‘) of infrared device to ‘GND’ (terminal X6, No.14), and connect ‘power supply +’
of infrared device to ‘12V’ (terminal X6, No.14).

(1) Learn / erase remote controls
Adding extra remote controls (Learn): Press red button on the control board (see Fig.14 No.12), then
the ‘LED’ (see Fig. 14 No.11) will be on, it will turn off when you press any remote control button.
Press the same button, the ‘LED’ will flash at 2Hz frequency and then turn off; this indicates the
learning process is finished. If it fails to set, the ‘LED’ will turn off automatically after flashing for 1
second, you should follow the steps above to reset.
Up to 25 remote controls may be used.
To erase all remote controls: press and hold the red button on the control board until ‘LED’ turns on
and then turns off. This indicates that all the remote controls have been erased completely. You
should reprogram the remote control if you want to control this opener (see Adding extra remote
controls section).
(2) The remote control works in a single channel mode. It has four buttons. See Fig. 13. With each
press of the remote control button which has been programmed, the gate will close, stop, open or
stop cycle.
Warning: Notify the users that the gate is never to be operated unless it is in full view.
(3) Operation of the gates
The gates can be controlled by using remote control, single-button mode or three-button mode
external button switch.
zUnlock the gate opener with the key. Push the gates to the opened (retracted) position manually.
Lock the gate opener with the key
zTurn the power on.
zClose the gates by using remote control, single-button mode or three-button mode external
button switch. The No.2 gate-leaf will close first, and then the No.1 gate-leaf with electrical lock
will close after 3 seconds.
zThe gates will stop at its closed position automatically, or you can stop the gates at its closed
position by remote control, single-button mode or three-button mode external button switch. If
gates do not stop or bind before stopping, verify that the stop is firmly in place, and the force
adjustment knob for that gate on the control board is adjusted correctly. Adjust counter-clockwise
to reduce binding.
zOpen the gates by remote control, single-button mode or three-button mode external button
switch. Firstly, the electrical lock will be opened, the No.1 gate-leaf with lock will open, and then
the No.2 gate-leaf will open after 3 seconds.
zThe gates will stop at its opened position automatically, or you can stop the gates at its opened
position by remote control, single-button mode or three-button mode external button switch. If
gates do not stop or bind before stopping, verify that the stop is firmly in place, and the force
adjustment knob for that gate on the control board is adjusted correctly. Adjust counter-clockwise
to reduce binding.
zTotal working time: 24 seconds.
Note: The gate will return to open if press ‘OPEN’ button on the three-button mode external button
switch during closing, the beeper will ring. We call this Open priority.

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.
