Technical info
- Installing an electromagnet is particularly easy. There is no need to be a specialist installer of locks.
- The magnet attracts the armature plate and holds it tight. That is the reason why the plate has to be fitted as close as possible to the magnet.
- A magnet correctly installed, never affects its surroundings because it is a closed magnetic field. When used correctly, there is no interference with nearby installations and no health risks.
- The electromagnetic locks EM are particularly well treated to resist corrosion.
- There is NO residual magnetism on the EM magnets! It means that as soon as the power is switched off, the lock is released immediately and there is no residual holding.
Troubleshooting:
Before requesting service or external assistance please check the following 2 points:
- The armature plate is too tight: This is a common error when you install a magnet for the first time. The installer is concerned when he sees that the plate is loose and he overtightens the screw, to crushing the rubber washer and clamping the whole set together. However, a door has an angular motion, and it is the flexibility of the armature plate that compensates for this movement. The more flexible the plate, the better the system will function.
(see: installation of the armature plate). - The voltage on the magnet connector is too low : This is another classic problem of first-time installation. The electromagnetic locks have to be powered in 12 VDC or 24 VDC minimum. If the voltage is lower, the holding force will be also lowered and the monitoring will not function properly.
Attention: Our magnets are supplied with a factory setting to 24VDC. If you power in 12VDC, do not forget to change the voltage selection

Water resistance:
The metal parts of the EM electromagnets are particularly resistant to the corrosion. They can be used in most external applications but care must be taken to protect the electrical parts and connections.
For external exposed installations, the 7500 N range is highly recommended.
Maintenance:
The EM electromagnets do not require special maintenance. It is important not to clean them with an abrasive or a solvent.
When using the EM electromagnets in a harsh environment, the magnetic tracks can be spayed with a thin film of Teflon (except in site where the Teflon is prohibited e.g.: nuclear plants).
