Conduit
In order to protect the wires, conduit must be preset into the concrete when it is poured. Wires
within the conduit shall be located or protected so that no damage can result from contact with
any rough or sharp part.
Concrete pad
The base unit of the gate operator requires a concrete pad in order to maintain proper stability.
The concrete pad should be approximately 300mm x 260mm x120mm deep in order to provide
for adequate operation.
Anchors
You can use the anchor bolts, anchors, washers, and nuts. These anchors must be set into the
concrete when it is poured, or you can use wedge anchors.

Limit switch
AC-2000 -Magnets for limit (see Fig.10)
Install the magnet as shown in Fig.10 below. The magnet and limit switch are used to
control the position of the gate.
When the magnet is installed, release the gear clutch and push the sliding gate manually to
pre-determine the position. Fix the magnet bracket to the gate and then tighten the gear
clutch. The lower bracket is for open position and upper bracket is for close position.
Finally adjust the magnet to the proper position by moving the gate with the motor. The
magnet should be 10~15mm away from the magnetic limit switch. If it is too far away, the
switch will fail to work. Adjust the position of the magnet until the positions of the opening
and closing meet the requirement.
Please note the position of two magnet brackets (fixed plate) are different: one is
upper and another is lower. Verify and if necessary exchange the two brackets
position. Also if necessary exchange the limit switch wires CL (close) and OP
(open).

AC-2000-Spring limit tch(see Fig.11)
To ensure safety, it is recommended to install limit devices at both ends of the gate to
prevent the gate from sliding out of the rails. The rails must be installed horizontally.
The spring limit switch and blocks are used to control the position of the gate.
When the block is installed, release the gear clutch with the key and push the sliding gate
manually to pre-determine the position, fix the block bracket to the gate and then tighten
the gear clutch with the key. Moving the gate electrically, adjust the block bracket to the
proper position until the position of the opening and closing meet the requirement.

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).
11
DIP Switch #5: Direction of gate opening.*
(* Direcon 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: Ifopening is to the left, the Limit Switch wires on the control board (yellow & red) need to
be reversed. The black wire stays the same.
12
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 OPENstall 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.
