Barrier Operator UTC-3306

This barrier operator is not for pedestrians!
Automatic gate openers are designed for vehicular traffic. They are powerful and can cause
serious bodily injury or death. Accordingly direct all pedestrian traffic to a separate walk-
through gate.
 Cut off the power supply before starting installation, operation or maintenance.
 The barrier operator must be secured to the ground.
 As for the electric cable type and section, we suggest to use the cable type of with a minimum section
of 2.0mm2
 Do not change the original inside wiring.
 If there is power failure, please switch off the power supply first, then open the door and rotate the
handle on the motor to manually open the boom completely.
 Keep the automatic control (push-button, remote control, etc.) out of the reach of children. The control
system must be installed a minimum height of 1.5m from the ground surface.
 Use transmitters or button only where you can see the gate clearly.
 Never open the door or the cover of the cabinet when the machine is running.
 Do not permit children to play on or around the gate.

Installation and Adjustments
1) Installing the barrier on the ground:
2) Installing the boom (Fig. 2)
3) Adjust the limit position. The barrier is supplied with the magnet limit switch and the mechanical limit
switch for optimum boom movement. Do not chance the limit position.

Boom Length
1) Adjust the vertical and horizontal line of the boom. If the boom needs to be shorter.
The boom may slope upwards aer becoming shorter.
The strength of the spring may have to be decreased,
refer to appendix.
Manually put up the boom perpendicularly. 1) Loosen the adjusng nuts.
2) Adjust the tuning screw and check the boom. If the
boom is perpendicular to the ground when it is open,

Boom Length (Continued)
2) If the boom needs to be longer.
The boom may slope downward aer becoming
longer.
The strength of the spring may have to be in-
creased, refer to appendix.
Manually put up the boom perpendicularly. 1) Loosen the adjusng nuts.
2) Adjust the tuning screw and check the boom. If the
boom is perpendicular to the ground when it is open,
Adjust the balance of the spring with boom.
The springs have been already adjusted to balance
with the 16’ boom. If the length of boom needs to
be chanced, the springs should be re-adjusted.

Electrical Safety Devices
1) The barrier’s limit switches, motor, and control unit are already connected.
2) One the photo cells, loop detector, and the supply voltage have not been connected.

Transmitter’s Code Setting:
Press “Learn button” until the Learn LED light turns on, then press button of your choice on the transmitter
until the Learn LED light flashes and goes out. The transmitter is now coded. Other transmitters can be cod-
ed in this manner.
Erase Transmitter’s Code:
Press the “Lean Button” and hold to make the “Lean LED” light go off. Now all the codes on the transmitter
have been cleared.

Safety Device Wiring (Sold Separately)

Photocell (N.C.)
 If the infrared ray is shut off when the gate is closing,
the gate opens instantly.
 If the infrared ray is shut off when the gate is open-
ing, the gate remains open.
Loop Detector (N.C.)
 If a car is in range of loop while gate is closing, the
gate will open.
 If a car is in the range of loop when the gate is open,
the gate remains open.
NOTE: If auto-closing function is valid, when an obstacle passes through the sensor
range, the gate will close automatically after a set delayed time. The delay time can
be adjusted from 1-120 seconds.

Loop Detector (N.O.) Dip1 should be Off
 If a car is in range of the sensor, the gate remains
open.
 When a car passes through the range of the sensor,
the gate closes.
External Terminal
 When a IC card reader is used, it must be connected with OPN and GND
