Magnetic plates

DANGER

Danger from strong magnetic fields

Strong permanent magnets generate intense magnetic fields that can interfere with or disable the function of pacemakers. This can cause serious health problems, including unconsciousness, heart attack or even death.

  • Maintain a minimum distance of 200 mm between persons concerned and the magnetic plates
  • Do not hold magnetic plates close to the chest area

WARNING

Serious injuries due to magnetic forces of attraction

Severe crushing injuries may result if the strong magnetic field of the permanent magnets in the magnetic plate unexpectedly attracts the components magnetically during assembly. The cover weakens the magnetic field and protects electrical components from magnetic influences.

  • Do not remove the protective cover
Magnetic plates 1:

Observe the alignment

Align the magnetic plates identically. The Beckhoff logo must always be on the same side.

If this is not observed, the adjacent magnetic plates repel each other. As a result, the coil unit cannot move without restriction. The system is not operational.

Magnetic plates 2:

Observe minimum gap

Keep the required minimum gap when mounting additional magnetic plates. This is 48 mm between hole centers. During mounting, maintain a distance of at least 10 cm between the magnetic plate to be mounted and the mechanically protected coil unit.

Failure to observe this can lead to complications during installation.

WARNING

Serious injuries due to uncontrolled movement of the machine carriage

If the strong magnetic field of the permanent magnets in the magnetic plate unexpectedly attracts the components magnetically during assembly, it is not possible to hold the machine carriage by hand. Severe injuries to limbs can be the result.

  • Secure the machine carriage mechanically against uncontrolled movements
  • Do not reach under the machine carriage or hold the machine carriage by hand
Clean the mounting surface on the machine bed and the magnetic plate
Push the machine carriage [1] to one end of the machine bed [2]
Mechanically secure the machine carriage against the forces of attraction and uncontrolled movements of the magnetic plate

Insert locating pins [3] into the machine bed
Pay attention to the insertion depth of the locating pins [3]

Check the alignment of the magnetic plate. Make sure that the Beckhoff logos are on the same side.
Magnetic plates 8:
Place the magnetic plate [4] on the locating pins [3]
Magnetic plates 9:
Insert screws [5] into the magnetic plate on the machine bed
Tighten the screws crosswise and from inside to outside

Observe tightening torque:

Remove the protective cover [6] on the mounted magnetic plates onto which the machine carriage is to be pushed. Do not dispose of the protective cover and keep it for subsequent transport of the machine or system.

Other magnetic plates

Magnetic plates 11:
Push the machine carriage [1] onto the mounted magnetic plates [2]
Secure the machine carriage mechanically against uncontrolled movements
Mount the other magnetic plates in the same way

Once all components have been fitted and you start the machine or system:

Remove all protective covers [3] on all magnetic plates
