1.Important safety information
Carefully read and follow all safety precaution and warnings before attempting to install and use
this operator, incorrect installation can lead to severe injury.
zThe gate operator should be installed by a qualified technician; otherwise, serious personal
injury or property damage may occur.
zThe auto-reverse function must be checked during installation to ensure that the gate can
auto-reverse in the event of obstruction.
zThis auto-reverse function should be regularly inspected and adjusted, if necessary.
zWhen opening or closing the gate, do not attempt to walk or drive through the gate.
zChildren should not be allowed to play near or operate automatic gates.
zInstall the gate operator on the inside of the property, DO NOT install it on the outside of the
property where the public has access to it.
zBe careful when in close proximity to moving parts where hands or fingers could be
pinched.
zDo not allow control devices to be placed so that a person can access them by reaching
through the gate.
zIn the event of power failure, an emergency release key allows you to operate the gate
manually.
zThe operator should be switched off before repairing it or opening its cover.
zPlease erase and reset the code after installing the operator.
2. Main features
zThe device is used to drive the sliding gate.
zFor your safety, the operator will stop and reverse if it was obstructed on closing and stop
when it was obstructed on opening.
zSupports up to 100 remote controls.
zInfrared terminal (N.C) is supplied to use.
zAuto-close feature is available for this operator.
zPedestrian mode.

4. Working principle and main structure
The device is composed of a single-phase motor, worm and worm gear. The main shaft of the
motor rotates the worm with the clutch engaged, the worm rotates the worm gear and output
gear, which pushes rack attached to the sliding gate, thus moving the gate. The dimension is
shown in Fig.1.
Fig.1
The structure of the motor and worm is shown in Fig2. Output torque can be adjusted by
pressure screw, tighten (or release) the pressure screw to increase (or decrease) the output
torque.

Release function: the worm gear components are shown in Fig.3. It includes a pair of plastic
gear clutches. In case of power failure you can use the key to release the clutch, then the gate
can be moved manually.
The device is well lubricated and cooled by the cooling oil (#25 transformer oil), which fills the
whole device, including the stator, the rotator of the motor, the worm gear and the worm.

The device is equipped with a thermal protector, the thermal protector will switch off the motor
automatically in case of temperature is higher than 95ºC and switch on the motor automatically
when the temperature is lower than 60±5ºC.
5. Installation and adjustment
The AR2000 rack-driven gate operator operates by forcing a drive rack past a drive gear. The
entire configuration is shown in the diagram below.

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. If you have installed an external button switch, we advise you to use
two conduits: one for main power wire, another one for control wire. Always separate power
wires from control wires.
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 400mm x 250mm x 200mm 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.
Fig.5
Operator Base
Mount the gate operator base to the concrete pad.
Operator
Mount the gate operator to the base using nuts and washers. Verify that the operator is leveled
properly.
Installing the rack (see Fig.6)
Weld the steel rack
zManually move the gate to its closing position.
zPlace the three threaded pawls (in the same package with rack) on the rack element.
zLay the first piece of rack on the gear and weld the first threaded pawl on the gate.
zMove the gate manually, checking if the rack is resting on the gear, and weld the second
and third pawls.
zBring another rack element near to the previous one. Move the gate manually and weld the
three pawls as the first rack, thus proceeding until the gate is fully covered.
zWhen the rack has been installed, to ensure it meshes correctly with the gear.
zThe space between rack and gear is about 1mm.
Screw the nylon rack
zManually move the gate to its closing position.
zLay the first piece of rack on the gear and mark the drilling point on the gate, drill a hole and
screw the bolt.
zMove the gate manually, checking if the rack is resting on the gear, and repeat the above
operations.
zBring another rack element near to the previous one. Move the gate manually and carry out
the securing operations, thus proceeding until the gate is fully covered.

Magnets for limit switch
Install the magnet as shown in Fig.7 and Fig.8 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. Fit the magnet bracket to the rack and then tighten the gear clutch.
The lower bracket is for open position and higher bracket is for close position. Fix the magnet to
the bracket. 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 magnetic limit switch until the positions of the
opening and closing meet the requirement.

6. Electrical
Make sure that the power is OFF before making any electrical connections. Remove the cover of
the control box, perform the wiring and replace the cover again. (Refer to Fig.9 control board
scheme and wiring notes)

zRemote control: The remote control works in a single channel mode. It has four buttons.
See Fig.10 Remote control. The function of button 1, button 2 and button3 are the same.
With each press of the remote control button, which has been programmed, the gate will
close, stop, open or stop cycle. Button 4 is available to set pedestrian mode.
You can program/learn button 1, button 2, button 3 individually. You also can program/learn
two buttons or three buttons together, but you need repeat the program/learn process if you
want to use more than one button.
