At present, the three-roll gate is the most widely used gate in the intelligent tunnel gate industry, and is suitable for all kinds of public places that require pedestrians to pass in order, such as tourist attractions, subway stations, exhibition halls, cinemas, docks, and train stations. Place of ticket. Then, how to solve the three-roller brake failure during use? The following innovation pass Xiaobian to introduce you to the three roll gate common eight major faults and solutions. First, the turnstile gate opening can not be timely check the motherboard H2 <br> <br> reset position if there is an output voltage of 12V, the motherboard is not likely to have a problem. The metal switch is used to block the reset switch head. The main board is red, and the red light at the end of the reset switch indicates that there is no problem. Which one is not bright and which one is problematic. Second, open the gate, reset again in the opposite direction after the brake B, adjust the position of the light block (see 4, -B); A. Open the movement cover and check whether the normally open and normally closed contacts of the left and right travel switches are sensitive; C. Adjust the positions of the left and right travel switches: When the normal left and right open doors are unlocked, the left and right positioning arms cannot touch the travel switch (Note: The gap between the two is as small as possible). Third, knocking <br> <br> processing method when turnstile gate opening: intensity regulator damper Size Fourth, buzzing <br> <br> processing method when turnstile gate opening: four base angle adjusting screws solenoid, the solenoid pull reduced gap 5. The three-roller gate shall not be manually operated on the rod 1. Check whether the electromagnet of the power-off falling rod is used to attract the iron block; 2. Is there a DC12V power supply for the electromagnet with the power-off lever? 3, the electromagnetic power off the device to see if the top of the rod to the spring plate in the turntable, and if so, then move the entire device, so that the two do not come into contact <br> <br> six, effective gate opening signal to the gates No action 1) When the main board indicator is normal, L7 or L8 indicator will flash intermittently and the direction indicator will turn into a green arrow (here contains 2 signals in different directions) when the valid opening signal is given. The gate has no action: Detection method: Detect PX terminal PC, PD output voltage (AC18V), detect F2 (3A) fuse is blown; if normal, detect DX terminal MA, MB whether there is a voltage output (DC24V), if the output , Check whether the motor connection line off; if the motor is damaged; 2) The main board indicator light is off, LED digital tube is not displayed: Detection method: Detect the voltage output of the PX terminal's PA and PB (AC12V); detect whether the F1 (2A) fuse is blown. If all of the above are normal, it is determined that the motherboard is damaged; VII. When the gate turns off when the gate is in operation 1) Check whether the clip spring on the falling rod mechanism falls off and whether the lock of the brake rod is seriously worn; 2) If the drop mechanism is loose, it will cause the position deviation: the spring piece of the drop mechanism should have a slight gap with the lock head of the brake lever; 3) The electromagnet is in good condition: the electromagnet should be hot during normal operation; 4) Check the voltage output (DC24V) of LOCK1 and LOCK2 of the MX terminal on the mainboard, otherwise the mainboard will be damaged. Eight, the gate can be freely rotated in one direction, one direction can not open the gate A, open the movement cover, observe the left and right positioning arm is back to the original position or stuck; B. Enter debugging menu P00, turn the synchronization wheel to bring the light block, adjust the position of the light block: a. When the red light of the unlocking photoelectric switch is on, the left and right positioning arms should be stuck on the positioning dial of the movement (left and right gaps are equal); b. When the green light of the unlock photoelectric switch is on, the left and right positioning arms should deviate from the positioning dial of the movement (equal left and right gaps).
