What are the common faults of electromagnetic lock induction?

1 Question: Why does the electromagnetic lock make a loud noise when closing the door?
Answer:
a. Check whether there is a rubber gasket installed.
b. Check the iron plate end to see if the screws are too loose.
c. Check whether the distance between the magnetic lock body and the suction plate is appropriate.
2 Question: Why can't the iron plate be firmly sucked after the magnetic lock has been used for a period of time?
Answer:
a. Check whether the "power and voltage" 1A/12V/24V output of the power supply is reduced.
b. Check whether there is foreign matter on the surface of the magnet (such as dust, rust, foreign matter, etc.).
3Q: Why does the iron plate of the magnetic lock need to be adjusted frequently?
Answer:
a. Check whether the iron plate is equipped with pins.
b. Check whether the iron plate is equipped with rubber pads.
c. Suggest customers to apply "screw fixing agent" to the screws.
4Q: After the iron plate is sucked, it feels a slight vibration and the suction is insufficient?
Answer:
a. Check whether the main surface of the magnetic lock and the iron plate are completely sucked and there are no foreign objects, or loosen the iron plate and try it.
b. Check whether the voltage and current are satisfactory.
5Q: Why is the magnetic lock delayed, but it is ineffective?
Answer:
a. The "delay adjustment" of the electromagnetic lock starts timing after power is turned on, not after the door is closed.
b. The delay of the magnetic lock is 0, 3, 6, and 9 seconds. Check whether the setting is always set to 9 seconds.
6Q: Why is the magnetic lock powered, but the red LED light is dim and it cannot be sucked?
Answer: Check whether the voltage is sufficient to supply the electromagnetic lock requirements (1A current/12V voltage should be supplied)
Q7: Why is the magnetic lock powered on and attracted, but the red LED light is always on, and the green light is not on?
A: The induction element of the magnetic lock may be damaged and needs to be replaced.
Q8: Why can't the double-door magnetic lock be attracted after a period of time?
A: The double-door magnetic lock consumes more power. Check whether the power supply is sufficient (whether it is sufficient for the required current and voltage of the double-door electromagnetic lock, or whether there is line loss).
Q9: Why does the magnetic lock controller not work?
A: Check whether the "output" contact of the controller is correct.
Q10: How to distinguish the high-end and low-end of the magnetic lock, good or bad?
A: The simple and effective method is to choose a brand lock
