Common problems and solutions for security doors

The security door may encounter a variety of common problems during use, including but not limited to the power indicator not lighting up, no alarm, too long alarm time, and random alarms without reason. For these problems, there are the following solutions: The power indicator is not lighting up: Check whether the incoming aviation plug is firmly plugged in and whether the power cord is in good condition. No alarm: Check whether there are interference sources around, try to change the crystal oscillator to change the frequency, if the infrared is abnormal, it is recommended to contact the manufacturer for replacement and repair. The alarm time is too long: Check whether the alarm duration setting and infrared count are normal. Random alarms without reason: First check whether the interference signal light is always on. If it is always on, it means that there is interference around the security door. If the interference signal light is not on, you can adjust the working frequency of the security door. In addition, there are some other problems and their solutions: The security door cannot be turned on: If the power indicator light is on, check whether the power supply in the chassis is firmly plugged in; if the power indicator light is not on, check whether the incoming aviation plug is firmly plugged in and whether the power cord is in good condition. ‌ People passing through are not counted: Check whether the infrared sensing line is firmly plugged in and whether the infrared head is blocked. ‌ False alarm problem: Ensure stable voltage, choose a good surrounding environment, conduct appropriate debugging, and keep enough spacing when installing multiple security doors. ‌ Through the above methods, most of the common problems encountered by security doors during use can be effectively solved, ensuring the normal operation and efficient use of security doors. ‌

Common faults and maintenance methods of security doors

Security doors may have various faults due to improper operation or other reasons during daily use. There are many kinds of these faults. When we repair security doors, we need to understand the specific faults and causes of security doors before we can further know how to repair security doors. Today, I will introduce some common faults and repair methods of security doors. Security door fault 1: The power indicator is not on Solution: Check whether the incoming line plug is firmly plugged in and whether the power cord is in good condition. Security door fault 2: No alarm Solution: Check whether there is an interference source around, try to change the crystal oscillator to change the frequency (different security doors are equipped with manuals for specific operation. If the infrared is abnormal, it is recommended to contact the factory for replacement and repair. Security door fault 3: The alarm time is too long Solution: Check whether the alarm duration setting and infrared counting are normal. Security door fault 4: Unexplained alarm Solution: First check the interference signal light. If it is always on, it means that there is interference around the security door. If the interference signal light is not on, you can adjust the working frequency of the security door.

What are the common faults of X-ray machines and how to solve them?

The common faults of X-ray machines and their troubleshooting methods are as follows: Power failure. Check whether the power cord is plugged in tightly. If it is loose, plug it in again; replace the power cord to ensure that it is intact; check whether the power plug is damaged. The high voltage of the X-ray generator cannot be turned on. Check whether the position of the X-ray protection system panel and the X-ray warning sign are normal; check whether the conductivity of the internal circulation water is too high or the water level of the internal circulation water is too low; turn on the high-voltage generator and check whether each switch is normal and whether the fuse is blown according to the circuit diagram; check whether the X-ray tube is damaged and whether the connection with the high-voltage cable is normal.
