1. The motor rotates back and forth after power on
1) Determine whether the unlocking photoelectric switch is exposed to strong light (generally refers to outdoor installation and debugging): Detection method: cover the chassis cover; if you need to open the chassis or movement cover, please cover the unlocking photoelectricity with a dark color opaque object Switch to debug! !
2) Test unlock photoelectric switch:
A. The three-roller gate checks whether the photoelectric switch of the unlocking board is powered! Check whether the 4PIN thread is loose or poor contact;
B. Enter the debugging menu P00, turn the synchronous wheel to drive the light barrier to turn on the photocoupler 1 and the photocoupler 2, the red and green indicator lights should turn on in sequence, otherwise the unlock photoelectric switch is damaged;
3) Check whether the connection between the unlocking photoelectric switch and the motherboard is reliable;
4) When the red and green lights of the unlocked photoelectric switch are on, the L5 and L2 indicators on the motherboard will turn on, otherwise the motherboard will be damaged.
2. The gate has no action after giving a valid opening signal
1) The indicator light of the main board of the three-roller gate is normal. When a valid opening signal is given, the L7 or L8 indicator light flashes intermittently and the direction indicator board will turn into a green arrow (here, there are 2 signals in different directions).
Detection method: detect the output voltage (AC18V) of the PC and PD of the PX terminal, detect whether the fuse (2A) fuse is blown; if normal, detect whether there is voltage output (DC24V) at both ends of the MA and MB of the DX terminal, if there is output To detect whether the motor connection is de-soldered; whether the motor is damaged;
2) The indicators on the main board are off, and the LED digital tube has no display:
Detection method: detect the voltage output (AC12V) of PA and PB at the PX terminal; detect whether the fuse (1A) fuse is blown. If the above is normal, judge the motherboard is damaged;
3. The gate will not reset after opening
The gate will not be reset immediately after the pedestrian passes, (you can pass several people continuously), and the gate will be locked after a delay:
Detection method: first check the reset photoelectric switch (same as unlocking the photoelectric switch); the L4 indicator on the main board will turn on when there is a signal output, otherwise the main board will be damaged; check whether the parameter setting P08 of the main board is set with memory;
4. The gate can rotate freely in one direction, and the gate cannot be opened in one direction
A. Open the movement cover and observe whether the left and right positioning arms return to the original position or get stuck;
B. Enter the debugging menu P00, turn the synchronous wheel to drive the light barrier, adjust the position of the light barrier:
a. When the red light of the unlock photoelectric switch is on, the left and right positioning arms should be stuck on the positioning dial of the movement (the 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 (the left and right gaps are equal);
5. After power on, the pole can not be put on or the lever can be dropped when the three-roller gate is running.
1) Check whether the circlip on the lever-dropping mechanism has fallen off and whether the lock of the brake lever is severely worn;
2) Whether the lever-dropping mechanism is loose or not leading to a positional deviation: the spring-loading mechanism of the lever-dropping mechanism should have a slight gap with the lock of the brake lever
3) Whether the electromagnet is intact: the electromagnet should be hot during normal operation;
4) Detect the voltage output (DC24V) of LOCK1 and LOCK2 of the MX terminal on the motherboard, otherwise the motherboard will be damaged.
6. After opening and resetting, open again in the opposite direction
A. Open the movement cover and check whether the normally open and normally closed contacts of the left and right travel switches are sensitive;
B. Adjust the position of the light barrier (see 4, -B);
C. Adjust the position of the left and right travel switches: when the left and right gates are unlocked normally, the left and right positioning arms cannot touch the travel switch (note: the gap between the two should be as small as possible).
7. No change in direction indicator board
Industrial Park Sound Barrier is mainly used as a noise reduction of road, highway, viaduct and other noise sources. It is a kind of barrier set at the side of road or railway in order to reduce the impact of vehicles' noise on residents nearby.
Noise Barrier advantages
• Good sound absorbing property
• Painted various colors, and can enrich sound barrier landscape
• It can be washed like glass
• Fireproofing, weather resistance
• Corrosion resistance
• Convenient installation
• Size and shape can be customized
• Light weight, recyclable
• Long service life, etc
