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 the rack attached to the sliding gate, thus moving the gate.
The device is installed with a thermal protector, the thermal protector will switch off the motor
automatically in case of the temperature is higher than 120°C and switch on the motor
automatically when the temperature is lower than 85°C

5°C.

5. Installation and adjustment

The AR-1450 rack-driven gate operator operates

by forcing a drive rack past a drive gear.

The entire configuration is shown in Fig.1. The gate operator must be installed on the inside of
the gate.
Gate preparation
Be sure the gate is properly installed and slides smoothly before installing the AR-1450
sliding gate operator. The gate must be plumb, level, and move freely.

Conduit
In order to protect the wires, use PVC conduit for control wires, conduit must be set 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 200mm x 200mm deep in order to provide
for adequate operation.
Anchors
You can use the anchors, bolts, washers and nuts that are provided with the operator. These
anchors must be set into the concrete when it is poured, or you can use wedge anchors.
Operator
In locations where ground freeze is possible, mount the gate operator on installation pad as
shown in Fig.2. Check the operator and make sure it is lined up with the gate.

Installation of rack (see Fig.3)

Fix the three nuts (in the same package with rack) on the rack element.
Lay the first piece of rack on the gear and weld the first nut on the gate.
Move the gate manually, checking if the rack is resting on the gear, and weld the second
and third nut.
Bring another rack element near to the previous one. Move the gate manually and weld the
three nuts as the first rack, thus proceeding until the gate is fully covered.
When the rack has been installed, to ensure it meshes correctly with the gear.
The space between rack and gear is about 1mm.

﹡

If you have installed an external

button  switch,  you  must  use  two
conduits:  one  for  main  power  wire,
another  one  for  low  voltage  wire
(button switch).

Fig.3

Magnets for limit switch
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.
Install the magnet as shown in Fig.4 and Fig.5. The magnet and limit switch are used to control
the position of the gate.
Release the gear clutch and push the sliding gate manually to pre-determine the position.
Solder 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. Adjust the
position of gate operator, the magnet should be 10~15mm away from the magnetic limit switch,
if too far away, the switch will fail to work. Moving the gate electrically, adjust the magnet to the
proper position until the position of the opening and closing meet the requirement.

and fast change the

open/close direction

which is determined by

the position of the gate

opener installed.

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.

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.
