Cost-Effective Low-Voltage DC Barrier Gates: Efficient Access Control Easy Installation & Maintenance
As a solution for vehicle access management, BRDC-110 DC road gates are widely used in parking lots, neighborhoods, industrial parks and other places. Its stability, reliability and automation features make it an important part of modern traffic management systems. BRDC-110 DC road gates can realize automated management through a variety of control methods: -
Remote control: switch control through remote control, convenient for remote operation.
-
Auto-sensing: Automatically open the gate after detecting the vehicle through sensors (such as infrared, ground sensors, etc.).
-
License plate recognition: Automatically open the gate by recognizing the license plate information of vehicles.

Barrier Commissioning Steps
Step 1: Match The Rod And Spring
Stop the gate lever at about 45 degrees and check whether the lever will slowly drop or open the gate (if the gate is opened, explain the spring tension is too large (the rod is allowed to open the brake slowly if the spring tension is slightly larger). If the rod falls indicating insufficient spring tension).
Step 2: Limit Of Self Inspection Learning Switch Of Track Gate
- The normal startup of the controller is "00:00" and "e-00" alternately displayed. Press and hold the controller "close / turn up" for 2 seconds, and the track gate operates in the direction of closing. The controller scrolls from left to right to display "0 0 0 0", and the buzzer sounds rhythmically. When the motor runs to the closing limit, the controller displays static "0 0 0 0" and the buzzer stops ringing. At this time, the closing self-test is completed.
- After the closing self-test is completed, press and hold the controller "open / down" for 2 seconds, and the track gate operates in the opening direction. The controller scrolls from left to right to display "0 0 0 0", and the buzzer sounds rhythmically. When the motor runs to the opening limit, the controller buzzer sounds for a long time. At this time, the opening self-test is completed, and the gate can operate normally.
Step 3: Adjust The Horizontal And Vertical Position Of The Gate Lever - The pole exceeds 90 degrees after driving to the position (adjust the P-9 parameter to a large scale); The pole is less than 90 degrees(reduce the P-9 parameter).
- Close to the position where the pole is higher than the horizontal position (reduce the P-6 parameter); The pole is below the level position (increase P-6).
Note: 1. Judge whether the horizontal position of the fence pole and the advertising gate is in place (the pole contacts the ground motor will stop immediately (if the motor is still rotating after it is in placeincrease the P-6 parameter until the motor does not rotate after the pole reaches the ground. After debugging the parameters, the switch needs to be operated to see the position change.
Key Operation
The controller has four keys, namely "on / down", "return / stop", "set / save" and "off / up". You can set various parameters of the main board through these four keys.
Shortcut Key Operation
- Press the "on / down" button once in the mode without inserting the motor cable to display the software version number; Press the "off / up" key once to display the software date.
- In the normal working mode, under the display time page of the digital tube, short press "set / save" once to display the current value, short press "set / save" for the second time to display the change rate of hall, and short press "set / save" for the third time to display the internal voltage value of the controller; Short press "set / save" for the fourth time to display the power supply voltage value;
Key Function Description
-
Set / save key: enter the setting state and save the setting value.
-
On / down key: press this key to open the gate in normal working state. After entering the setting state, you can use this key to add menu items or adjust the setting value upward. In the parameter setting state, short press to add one each time. Press and hold continuously until the maximum value is reached, and then add from the minimum value.
-
Off / up key: press this key to close the gate in normal working state. After entering the setting state, you can use this key to reduce menu items or adjust the setting value downward. In the parameter setting state, short press to subtract one at a time. Long press to continuously decrease to the minimum value and then decrease from the maximum value.
-
Return / stop key: in normal working state, press this key to stop the brake. In the setting state, you can exit the setting state or return to the previous menu.
Parameter Menu
Operating Instructions
You can enter the parameter setting state by long pressing the "set / save" button for 3 seconds, and the LED will display "P-X". Select the menu items by pressing the two buttons "on / down" and "off / up" for a short time or a long time. Short press to increase or decrease one item at a time, and long press to increase or decrease continuously. Press the "set / save" key again to enter the setting of the specified item, and the "return / stop" key to exit the setting. After setting the specified parameters, you must press the "set / save" key to confirm it. The parameters set by pressing the "return / stop" key will not take effect. If there is no key within 45 seconds, the buzzer on the control panel will sound for a long time, exit the setting state and return to the normal working state. Parameter Command Value Table

- For all places involving angles, the closing position is 0 degrees.
- When the power supply voltage is too large (> 27V) or too small (< 18V), the controller will automatically protect and give an alarm.when the controller is protected, the motor, light box, ground sensor and other equipment will not work.
Remote Control Function
- Remote control pairing: long press the controller "set / save" for three seconds, find the P-F item, and press the "set / save" again to display "000". At this time, press any key of the remote control. At this time, after the controller makes a long sound, the display changes to P-F, indicating that the remote control is matched successfully.
- Clear the remote controller: long press "set / save" on the main board for three seconds, find the P-F item, press "set / save" again to display "000", adjust the value to 253, and press "set / save" again. At this time, after the main board makes a long sound, the display changes to P-F, and all remote controllers will be cleared.
- Fleet mode: long press "set / save" on the controller for three seconds, find item p-8, and then press "set / save" to display "0", adjust the value to 4, and then press "set / save" to exit the menu; After the road gate is opened in place, press the stop button of the remote controller for more than 2 seconds, and the fleet mode will start; To turn off the fleet mode, just press the off key of the remote controller.
Parameter Transfer Steps
-
Step 1: debug a template
-
Step 2: connect the template with the new controller
-
Step 3: power on the new controller
-
Step 4: long press the " down" button of the template, and check the "s -- s" displayed on the new controller, then the parameter transfer is successful
Common Problems And Solutions
Solution: check whether the left-right rotation mode of the P-D motor matches the current motor or not (you can re power on the controller after changing the parameters and conduct self-test again. Please refer to "Chapter 1, subsection 6, step 2" for whether the self-test of the track gate is normal) Solution: adjust the controller menu P-9 or P-6 parameters (refer to the parameter table for menu functions) Set the P-18 parameter of the controller to 1. If the relay is opened or closed once, it indicates that it has been opened / closed in place
Pay attention to observe whether the motor stops when the gate lever is in place, which means it is in place. If the gate lever is in place and the motor is still running, it is necessary to change the P-6 or P-9 parameters.
In the process of switching on and off, the nixie tube will have a dynamic "1" display. If the nixie tube display returns to the time interface, it indicates that it has been in place.
Solution: A. check whether the P-C parameter turns on the resistance rebound (if the controller parameter is greater than 100, the resistance rebound function fails) Solution: increase the value of P-C rebound function parameter Solution: increase the stability value of P-3 in place
