What is Magnet Door Status?

The magnet is running very warm, almost hot
'Power to Lock' devices such as magnetic locks can run warm as they require constant power to them, however, the most common causes of this are the magnet is 12v dc operation, but the power supply is 24v dc
Electrical resistance in the circuitry will create heat but if the power supply is providing insufficient amperage then the magnet will feel hot
Also, if there is a current drop because of a long cable run with an inadequate wire gauge, the magnet will not get sufficient current and will run hot

The armature plate is vibrating
This is due to either a faulty or under rated power supply, or incorrect alignment of the armature plate to the magnetic lock

The magnet does not lock, the door can be pulled open quite easily
The most common cause is incorrect alignment of the armature plate to the magnetic lock, a faulty or under rated power supply

Armature plate alignment

Tech Tips
This magnetic lock will operate via 12v dc, however, please ensure you check the wiring connections correctly for use with a 12v dc power power supply before you turn the power on
If you fail to check this, then you run the risk of either the magnetic lock running very hot or it not locking correctly
Eventually you will cause damage to the system you have installed
Periodically clean the surface of both the magnet and armature plate with light oil
'L' bracket installation

Z'L' bracket installation

Please consider if you require any fixing brackets. Typically an 'L' bracket is required for outward opening doors. A 'ZL' bracket is required for inward opening doors

L bracket weight: 0.050kg
L bracket size: 170l x 3d x (38 x 25h) mm
L bracket adjustment: 8 screw adjustment (4 each side) allowing the magnet to be aligned from -6mm forward to 19mm backward

ZL bracket weight: 0.300kg
ZL bracket size: 140l x 4d x 2 x (38h x 38h) mm
ZL bracket adjustment: 4 screw adjustment (2 each side) allowing the magnet to be aligned from -10mm forward to 25mm backward
