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.
 The gate operator should be installed by a qualified technician; otherwise, serious personal
injury or property damage may occur.
 The auto-reverse function must be checked during installation to ensure that the gate can
auto-reverse in the event of obstruction.
 This auto-reverse function should be regularly inspected and adjusted, if necessary.
 When opening or closing the gate, do not attempt to walk or drive through the gate.
 Children should not be allowed to play near or operate automatic gates.
 The automatic gate operator must be grounded.
 Install 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.
 Be careful when in close proximity to moving parts where hands or fingers could be
pinched.
 Do not allow control devices to be placed so that a person can access them by reaching
through the gate.
 In the event of power failure, an emergency release key allows you to operate the gate
manually.
 The operator should be switched off before repairing it or opening its cover.
 Please erase and reprogram the code after installing the operator.
2. Main features

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 DKC400(U)Y 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 DKC400(U)Y
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).

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.

Step #4
Now you will begin the installation by screwing the wires that are coming
from the small Receiver Board onto the Terminals (see Pic 1, right) from
the Control Board, in the following order:
Terminal 10 - GREEN WIRE
Terminal 11 - RED WIRE
Terminal 12 - YELLOW WIRE (any)
Terminal 13 - YELLOW & BLUE WIRE (any )
Terminal 14 - BLUE WIRE (any)
Step #5
Next, take the set of wires coming from the motor and connect the
red and black wires anywhere onto the plug.
(as shown on the pic, right)
Once you have connected those wires, you will then take that plug
and connect it to the Control Board on the section labeled:
"MOTOR"
(as shown on the pic, right)
