Setting of
the Control
Board
1. DIP Switches
The DIP switches are
used to set the limit
switch of the opener to
be NO or NC, auto close
time of the gate opener
and fast change the
open/close direction
which is determined by
the position of the gate
opener installed.
Setting of the Control Board
DIP Switch #1: Limit switch NC (normally closed) or NO (normally open)
DIP Switch #1
：
ON –NO /OFF –NC
This mode enables user to set the board to work with motor with NC or NO limit switch
NOTE: Factory default setting is NO
DIP Switch #2–#4: Auto close time of the gate opener
DIP Switch #2: ON – 12.5 Seconds OFF – 0 Seconds
DIP Switch #3: ON – 25 Seconds OFF – 0 Seconds
DIP Switch #4: ON – 45 Seconds OFF – 0 Seconds
NOTE: The auto-close function would be disabled if all 3 dip switches are turned to off (factory default
setting).

17
DIP Switch #5: Direction of gate opening.*
(* Direction from the inside of the property where the opener is installed.)
DIP Switch #5: OFF – Opens to the right.
DIP Switch #5: ON – Opens to the left.
Note: If opening is to the left, the Limit Switch wires on the control board (yellow & red) need to
be reversed. The black wire stays the same.

18
DIP Switch #6: (NOT USED)
DIP Switch #7–#8: Remote Control Button (yellow & blue) Setting
DIP Switch #7: ON – Yellow Button is Working OFF – Yellow Button is Not Working
DIP Switch #8: ON – Blue Button is Working OFF –Blue Button is Not Working
2. Potentiometers
The left potentiometer is to adjust the CLOSE stall force of the gate opener. The right Potentiometer is used to
adjust the OPEN stall force of the gate opener.
Turn the potentiometer clockwise to increase the stall force.
Turn the potentiometer counter-clockwise to decrease the stall force.

19
Test the reversing sensitivity
For the sake of safety, it is very important to test the reversing sensitivity as soon as the control board set is
finished.
The reversing sensitivity adjustment is inverse correlation with stall force adjustment in potentiometer 1 and
potentiometer 2. In other word, the stall force level is higher; the reversing sensitivity level is lower.
Put an immobile object along the gate path, and then operate the gate to strike it during the open and close
cycles. The gate must reverse as soon as object is struck with it. If the gate doesn’t reverse, please increase
the reversing sensitivity by turning the potentiometer in counter-clockwise direction. (Turning the stall force
potentiometer toward to “Light” position to increase the reversing sensitivity)
Note 1: If the sensitivity setting is too higher, the gate will stop or reverses very easy by itself
while there is little obstruction or resistance such as strong wind or heavy snow sometimes.
Note 2: Always check the gate reversing function every each time of control board set or
restart after power off.
