Magnetic plates

WARNING

Do not remove the protective cover

The cover weakens the magnetic field and protects electrical components from magnetic influences.

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.

Notice

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 part cannot move without restriction. The system is not operational.

Notice

Observe minimum clearance

Keep the required minimum distance 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 part.

Failure to observe this can lead to complications during installation.

Mounting

►Clean the mounting surface on the machine bed and the magnetic plate
Magnetic plates 3:
►Push the machine slide [1] to one end of the machine bed [2]

WARNING

Secure the machine slide sufficiently

Secure the machine slide mechanically against uncontrolled movements. Do not reach under the machine slide or hold the machine slide by hand.

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 slide by hand. Severe injuries to limbs can be the result.

►Mechanically secure the machine slide against the attractive forces and uncontrolled movements of the magnetic plate
Magnetic plates 4:
►Insert locating pins [3] into the machine bed
►Pay attention to the insertion depth of the locating pins [3]

Magnetic plates 5:
►Check the alignment of the magnetic plate. Make sure that the Beckhoff logos are on the same side.
Magnetic plates 6:
►Place the magnetic plate [4] on the locating pins [3]
Magnetic plates 7:
►Insert screws [5] into the magnetic plate on the machine bed
►Tighten the screws crosswise and from inside to outside

Observe tightening torque:

Quality of the screws = strength class 8.8

Magnetic plates 8:
►Remove the protective cover [6] on the mounted magnetic plates onto which the machine slide 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 9:
►Slide the machine slide [1] onto the mounted magnetic plates [2]
►Secure the machine slide mechanically against uncontrolled movements
►Mount the other magnetic plates in the same way
Magnetic plates 10:

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

►Remove all protective covers [3] on all magnetic plates
