In today's world we are more and more developed with our technology! Access security is used in our office buildings, parking lots and other places. Preventing people from entering has great convenience for management. A lot of turnstiles are now embedded in the access control board to air.

1. When we go in the gate of the embedded board, we need to find the control switch wire in the switch to get into the control board of the switch.

2. After we have connected the line, we need to swipe to test if the kanban is normal. If the direction of entering and exiting and what we want is different when we test, directly exchange the terminals of the card reader. Because the card reader interface in the board has a certain direction with a little care, it will reverse the direction.

3. When the card was swiped, there was a record on the computer software but there was no door open in the gate. At this time we needed to check that we were connecting the control board to the gate. It may be wrong when we wired it. The line will also cause the gate to not open the door. It is also possible that the load on the access is too large and the relay is burned out. So, friends at the construction site need to bring tools: voltmeters, clippers, screwdrivers, and other commonly used tools.

How to test if the relay is bad? (It needs to use our voltmeter)

a. Power on the control board, then adjust the voltmeter we want to use to the resistance file.

b, first try the voltmeter is normal, and then find NC, COM, NO on the board three terminal port c, put the electric pen into the NC and COM voltage meter ring; and then change the two electric pen to NO and COM Measurement, voltmeter does not ring. Indicates that this relay is normal. Need to repeat several times to test a few times, and then determine the good and bad.

d. After the test is repeated several times, it is determined that the board or the gate machine is broken, and it is necessary to contact the manufacturer whether to return the factory during the warranty period Q613739154.

In the use of the motherboard, all friends should pay attention to the board to pay attention to waterproof, as long as the board into the water after the manufacturers will not go to repair. Because the board enters water, it will corrode the board's copper wire. Even if it is repaired now, it will not be long before the board is broken. Clean the dust on the boards more than the number of boards to increase the use of a certain period!

The important thing to say three times: pay attention! Attention! Attention again! ! !
