2 SAFETY
DANGER!
Risk of electric shock!
The magnetic holding force is switched on and off with current pulses.
Electro permanent magnetic circular chucks use high magnetising and
demagnetising voltages. An electric shock can result in death or serious
injuries.
■
Always protect the junction box and rubberised cable against damage.
■
To exclude malfunctions and hazards for the operator, it must be ensured
that the junction box is sealed, in particular during wet work and after
any repair work. The same applies to connectors, current transmitters, slip
ring assemblies and carbon brush holders.
■
Electrical connections must always be installed by a qualified electri-
cian (as per VDE 1000 Part 10). The regulations of VDE 0100 must be
observed for all other work.
■
Work on electrical components is only permitted while the power supply
is switched off.
■
If the magnet has a connector, only unplug this once the demagnetising
cycles has been completed and the red signal light is permanently on.
Risk from electric arc.
DANGER!
Risk of crushing!
There is risk of crushing when placing ferromagnetic parts on the active
magnet.
■
Always position workpieces while the chuck is not magnetised.
■
The use of non-magnetic tools can exclude the risk of crushing or similar
injuries.
DANGER!
Hazard from ejected objects!
Incorrect operation can cause objects to be ejected, causing serious injuries
and even death.
■
The machine operator must be protected with a suitable shield installed
on the machine. This shield must be designed to absorb the kinetic ener-
gy of the part.
■
The magnetic circular chuck must always be securely attached to the
work surface of the machine tool. Check after assembly!
■
The stated maximum permissible speed must be observed (see section 3
“Technical specifications”).
■
The pole plate and the workpiece must be clean to allow for maximum
magnetic adhesion. Air gaps reduce magnetic adhesion! Clean the pole
plate and workpiece before positioning!
■
If the workpieces have a high non-magnetic material content, the ad-
hesion of the workpiece on the circular magnet is reduced, e.g. in case
of high levels of nickel or cast iron. The holding force may have to be
calculated.
■
The magnetic circular chuck must not be heated above 80 °C. Above this
temperature, magnetising of the magnetic circular chuck is eliminated.
