the majority of current market for this type

1.circuit malfunction or low voltage

2.The power supply wire is too thin and long and to cause big decrease of voltage.

3.Power supply is broken to cause no voltage output.

4.The positive and negative wire of power supply is connectied in reverse.

5.The power supply is no power input

1.Check the connection, and measure the voltage to see if it is normal

2.Modify or change the power supply wire to thicker one

3.Check the power polarity and correct the connection

4.Check to see if the power supply or controller is correctly connected to NC. Make sure to set up the controller

1.The mount plate and electromagnetic lock face is not in complete close

2.The mount plate is fixed too tight, no room to move

3.The electromagnetic lock and plate are not at the same level or the door is deformed or moved

4.The surface of electro magnetic lock and mount plate is not clean

5.Power supply with low voltage

6.The power supply wire is too thin and long

7.The electromagnetic lock is malfunction

1. Check the face of mount plate and magnetic lock, if the face of mount plate is deformed to cause no complete close to the lock. Please change the plate

2.Check the rubber gasket is put into the stick of plate, and adjust the bolt of plate not too tight at least a little movable

3.Adjust the surface of mount plate and electromagetic lock at the same lever and close completely.

4. Clean the surface of lock and plate. if rusted to affect its normal working, please change the part.

5.Use multimeter to check the voltage and current of electromagnetic lock to see if it is normal. or need repairing or changing power supply

6.Change into high quality power supply wire, better no more than 20 meters.

7.Repair or change the electromagnetic lock
