BR600T FAQ V4
Frequently Asked Question (FAQ) for BR600T barrier gate.
1. What is the correct counterweight spring for each model?
The spring has to have sufficient tension that can counter the weight of the arm. This helps to achieve
smooth motion and no shaking at the end of opening or closing. Different models have different
maximum arm lengths. The arm might be cut short to the actual lane width at the site. Different arm
length has a different weight and thus requiring different spring tension.
Different spring is required for different arm length (effective 1st June 2021) as per the following table:
In standard configuration, most of the time you
do not need to further tighten the spring. Minor
adjustments might be needed to compensate for
tension fluctuation due to manufacturing
tolerance.
For the arm's length of 1m to 1.5 (typical
motorcycle lane), you can just release all the
spring. Meaning no spring tension is required for
such a short arm.

2. Why is the barrier gate arm shaking at end of opening or closing?
If the correct counterweight spring has been used corresponding to the arm length, the arm shaking is
due to the movement momentum. There is 1 rubber cushion at each endpoint of opening or closing to
absorb all the momentum force that caused the arm to shake.
2.1 Please adjust the stopper screw to slightly press onto the rubber cushion until the arm is not
shaking at the end of opening or closing. The stopper screw should press down as minimum as
possible just enough to achieve no arm shaking.

STOPPER SCREW 2
2.2 Do not adjust the stopper screws to press excessively onto the rubber cushion. This will reduce the
lifetime of the rubber cushion. It will be troublesome if you need to keep on replacing the new rubber
cushion at the site.
2.3 Each same type of spring has a 5% tolerance of tension due to the manufacturing process. This
tolerance fluctuation can be offset by slightly tighten the spring if the arm still not perfectly no shaking.

3. Why the arm is still shaking despite the correct counterweight spring
and stopper screw level?
The barrier gate might have been enduring this shaking due to improper spring calibration since the
first day of installation, after changing a new arm of different lengths or adding heavy signage. Re-
calibrating the arm now is already too late as the continuous long-term shaking has caused irreversible
mechanical wear.
3.1 Dismantle the drive crank and visually check the arm lock slot inside the drive crank.
3.2 The pin lock mechanism and pin slot will be subjected to the worst mechanical wear. The arm
will shake at the end of opening and closing when the pin lock no longer perfectly fits into the pin slot
tightly.
3.3 Depending on how long the entire mechanism is subjected to the arm shaking, another
mechanism might also suffer mechanical wear that can contribute to arm shaking. We advise
replacing sending the machine back to us for diagnosis and repair. Charges might apply as this is not
considered a manufacturing defect.

4. Why barrier arm auto-reverse or stop halfway?
Our barrier gate controller will auto-reverse the arm at any point of the trajectory if detect a high
current here the arm has sufficiently big difficulty to continue closing. It could be due to the spring
pulling too hard or blocked by an obstacle at the lane.
4.1 If the barrier arm is cut shorter than the initially calibrated arm length, please re-calibrate the
counterweight spring tension base on the model as per FAQ 1. The spring tension needs to be
calibrated again if the arm length changed.
4.2 In some situations where the arm length is cut too short beyond the minimum tension of the dual
spring installed. If this is the case, 1 of the counterweight spring needs to be removed by fully
unscrew the spring pin below and remove 2 nuts that hold the spring to balance the crank on
top. After that adjust the tension of the remaining single spring accordingly.
4.3 The next potential fault is the big capacitor connected to the controller. A weak capacitor will
cause the arm to stop halfway or the arm auto reversed after reaching the end of opening/closing.
Please follow FAQ 7 to replace the capacitor.

5. What is the problem symptom if the capacitor is faulty?
As with any electronic component, it is natural that the capacitor will degrade over time. The purpose
of the capacitor is to provide a sufficient initial charge to move our Bluespeed AC motor.
5.1 If the capacitor is a malfunction, the barrier arm will not move at all while fan still running. We
can identify the fan operation by hearing airflow noise when it turns on.
5.2 If the capacitor is weak, the barrier arm will stop or auto-reverse at any point of the movement
intermittently.
5.3 Try to replace with another capacitor from the adjacent barrier gate to verify if the arm has
resumed normal operation. You can purchase the original MAG capacitor from us to replace at the
site to ensure the correct operation of the barrier gate.
6. Why barrier gate arm is not in a perfectly horizontal position when close
DOWN?
After fully closed, the arm seemed to be tilted slightly up or dropped slightly down instead of a perfect
horizontal straight line. The main reason for this issue is either the proximity limit sensor is incorrect or
the drive shaft position needs adjustment.

BR600T FAQ V4
6.1 An electronic proximity sensor is used to determine the stop position of the arm. The arm could
stop earlier or later depending on the position of the magnet bolt. Check the magnet bolt position
on the electronic proximity sensor is in the correct position.
Refer to the picture step by step below:
6.2 In some sites where the road might be slanted, the arm might still not in a horizontal position after
adjusting the electronic limit switch. If this is the case, then please adjust the driveshaft.
6.2.1 Turn the edge screw anti-clockwise to loosen the driveshaft for adjustment.
6.2.2 If the arm above the horizontal line, turn the driveshaft clockwise to lower down the arm.
6.2.3 If the arm below the horizontal line, turn the driveshaft anti-clockwise the rise up the arm.
6.2.4 Tighten back the edge screw to make sure the driveshaft won’t move while the barrier
operates.
Step 1:
Open barrier panel cover and look for the
electronic limit switch. On the side of AC
Motor, behind to initiative crank.
Step 2:
The barrier arm will stop at a certain position when the
magnet bolt is aligned with the proximity limit sensor.
If your magnet bolt sensor is aligned with the proximity
limit sensor too early before the arm can fully close
down, that is why your arm will not horizontal when down.

7. Why the arm does not move after pressing the push button (Up/Down)
or flashing card on the reader?
Up/Down/Stop LED on controller board will light up to confirm the signal is well received. A few
possibilities are depending on the response of the push-button input LED on the control board.
7.1 If all LEDs on the control board light up constantly without blinking after restarting the
board by turning it off and on again, it means the board could be corrupted due to lightning surge
or power surge. Please send the board back to us for further diagnosis and repair attempts.
7.2 We recommend you install a surge protector or isolator at UP, DOWN, STOP, COM input
on the control board to avoid being damaged by surge. Refer to the diagram below.
7.3 If the all up/down/stop LED on the control board does NOT light up corresponding to the
push-button pressed or flashcard at the reader, it means the signal is NOT well received. Please
check if the Up/Down/ STOP/COM wiring from the push button to the barrier controller board is
broken.

7.4 If all up/down/stop LED on the control board light up correctly corresponding to the push-
button pressed and AC motor fan triggered to start running, it means the board well received the
push button’s signal. The most likely cause for the arm not moving is the total malfunction
capacitor. Please follow FAQ 7 to replace it.
7.5 If the problem persists after replacing the capacitor, then try manually triggering the OPEN
or CLOSE signal on the control board by a short wire. If the arm still not moving, please kindly
replace the control board. If the arm is moving, then please check for possible defective push
buttons or defective relay output at the access controller.

8. Why barrier arm does not close down after the vehicle completely
passed through the loop coil?
This is caused by the access controller relay still holding the trigger signal even though the car has
completely passed through the loop coil. The arm will not descend despite receiving the valid signal
from the loop detector if our barrier controller keeps receiving a continuous UP dry contact signal from
the access controller.
You will get the same problem if you keep on pressing the push button until the car has completely
passed through the loop coil. Typically a car will need 4 sec to completely pass through the loop coil
from the moment user flashed the card at the access controller.
8.1 Please set your access controller relay release time to 1 second.
8.2 If you are using a Soyal controller reader:
(Example for AR721H) this will be the command to enter on the numeric keypad:
i. Enter Program Mode:*123456#
ii. Set Relay Trigger Time:02*001#
iii. Exit Program Mode: *#
9. Why the barrier arm close earlier before the vehicle completely passes
through the loop coil?
The main reason for this issue is because the loop detector sends a signal to the barrier board without
detecting any vehicle. This is either caused by the loop coil not installed properly (loop coil damaged
and cause interference to loop detector) or the loop detector is faulty. The Loop coil installed
underneath the ground is subject to damaging weather conditioning.
9.1 Please check the loop detector LED, during standby mode, if there is no car on top of the Loop
coil, the Red LED with light up for power. When the car is on top of the loop coil, the Green LED
will light up. After the vehicle has completely passed through the loop coil the Green LED will turn
off and the barrier arm will be closed.
9.2 The Green LED will keep light up when a vehicle passing through the loop coil. If the loop
detector LED response differently than described here, then the loop detector is faulty.
