1 Introduction
Overview1.1
The Barrier uses digital variable frequency servo controller, allowing stepless speed control of
the drive motor without loss of output torque. The opening and closing time of the Barrier can
be set from 1 s to 4 s and from 2 s to 6 s respectively, and the Barrier can be controlled by a
remote control, with a maximum distance of 50 m.
The Barrier is suitable for scenes such as parking entrance and exit control for supermarkets,
hotels, governments, schools, airports, factories, public security and judiciary authorities and
more.
Features1.2
Servo Self-optimization of Barrier Arm Stability
The rising and falling stability of the barrier arm can be set up respectively, after which,
regardless of operation speed, the variable frequency servo controller can automatically detect,
self-optimize, and eliminate barrier arm shaking. In this way, user experience can be improved
and the mechanical and electrical service life of the Barrier can be greatly extended.
Free of Sensor and Electrical Maintenance
The Barrier uses brushless motor with angle encoder integrated internally. All-digital servo
controller makes in-place detection free of sensor. No need of electrical maintenance avoids
device wearing and hidden troubles.
Anti-condensation in Cold Weather
The barrier motor is still powered on with low consumption when it stops working, which makes
the motor temperature stay normal even in freezing cold environment. With the lubricating oil
not frozen, the Barrier can work normally.
Auto Opening in Case of Power Failure
If the angle between the barrier arm and the horizontal plane is smaller than 45° during power
failure, the barrier arm will automatically fall to the closing state by default. However, if proper
rubber gaskets and springs for power-off opening are used, when the Barrier is suddenly
powered off, the barrier arm will automatically and slowly rise to the opening state.

User’s Manual

Manual Opening, Closing and Locking of Barrier Arm during Power Failure
During power failure, manually rotate the manual handle or locking handle to operate the
barrier arm.
The barrier arm can be locked at any position between horizontal and vertical positions. When
the barrier motor stops, swipe down the locking button on the manual handle or locking handle
to lock the Barrier. It will not be unlocked even if it is powered on. Swipe up the locking button
on the manual handle or locking handle to unlock the Barrier.
Do not use this function when the power is on; otherwise it might cause hand injury and serious
damage to the motor.

Loop Anti-smashing/Arm Falling
The falling barrier arm will immediately rise to vertical position if the LOOP1 signal is triggered,
during which the arm will not fall down until the loop input returns to normal state.
This function is not available when the angle between the arm and water level smaller than 9°.
Rising Priority
If a vehicle is about to pass when the barrier arm falls, the security guard can press the rising
signal on the remote control to make it immediately rise to the opening state, avoiding the
vehicle being smashed.
Auto Delay Closing
When enabling this function, after the barrier arm rises to the vertical position, it will
automatically fall to original place after certain delay if neither rising nor falling inputs are
triggered. The delay time (1 s–90 s) and enable/disable switch can be configured by user
through programming. It is disabled by default.
Auto Closing by Triggering Loop 1
If neither rising nor falling inputs are triggered, the risen barrier arm will automatically fall to
original position after vehicle leaves loop 1.
Auto Opening by Triggering Loop 2
The LOOP2 input will only trigger the barrier to open when its arm is at horizontal and closed
state, auto-closing of the Barrier is not available.
Smooth Mode
Press and hold the stop key on the remote control for 3 seconds, and the barrier arm
automatically rises and keeps vertical.Any falling action will be ignored until you press and hold
the close key for 3 seconds to disable the smooth mode.
