the down limit has been found. At this moment, the gate stops, and you need to manually
find the vertical and horizontal positions of the boom:
1) Press and hold Open, the boom works in the opening direction, until it is in the
required horizontal position.
2) Press Settings to confirm the horizontal position, then the LED shows L-02, meaning
that the boom gate finishes finding the horizontal position.
3) Continue to press and hold Open until the boom is in the desired opening position.
4) Press Settings to confirm the position. After you hear the sound from the buzzer, the
boom gate goes back to the normal working status.
If the boom does not reach the desired position after adjustment, you can press Open or
Close to adjust the position. During the adjustment process, if you do not release the Open
or Close button when the boom reaches the up or down limit, the controller will stop the
motor, and the buzzer makes continuous buzzes for alarm.
If H-33 is set to 2, the boom gate can work normally after manual adjustment. If H-33 is set
to 0 or 1, the parameters manually adjusted are saved, and they will take effect only when
H-33 is set to 2.
H-38 coil signal buzzer
You can set whether the boom gate buzzes when it receives coil or radar signals for
anti-smashing. The parameter is 0 by default, meaning no buzzes when the boom gate receives
coil or radar signals, 1 means the boom gate buzzes.
H -45 speed of auto delay closing
When F-10 (automatic delay closing time) is greater than 0, after the countdown finishes, the
boom gate opens at H-45 speed. The greater the value is, the faster the speed will be. When the
spring tension is large, the H-45 speed is too small, making the boom open when it is
obstructed during closing, you can increase the value appropriately.
H-46 auto opening time if low voltage occurs
This parameter defines the automatic opening function in case of power failure. It works with
H-47. When the power supply voltage is lower than the defined H-47 value, and the low voltage
continues for the defined H-46 value, the boom gate automatically opens. After it is opened, the
digital tube displays loxx (xx indicates the value of H-47). This function is available when an
ultracapacitor backup power module is installed. If H-46 is set to 0, it means that the function is
turned off.
H-47 auto opening when reaching the low voltage threshold
This parameter defines the voltage that the boom gate opens in case of power failure. It works
with H-46. In case of power failure, the boom gate automatically opens when the voltage is
lower than the defined H-47 value for more than the time defined in H-46.
3.4.2.3 Error Code
When the controller detects an exception, error codes as shown in the following table will be
displayed.
Table 3-9 Error code
Error Code Reason
Er.ob The boom reverses or stops when it is obstructed during the opening process.
