Troubleshooting
Problem Possible cause Corrective action
The workpiece shifts on the
magnetic chuck because it is
not properly clamped
The magnetization cycle has
not been performed correctly.
Check the electric connec-
tions between the control
unit and the magnetic chuck.
The magnetization power ad-
justed on the remote control
not sufficient.
If the remote control with
adjustable power is used,
increase the power and re-
peat the magnetization cycle.
The residual current device
disconnects the circuit
Current leaks out of the in-
tended circuit.
Disconnect the discharge
cable of the magnetic chuck
and make sure there is no
earth leakage
After having turned on the
power supply, the control unit
remains switched off.
The feeder cable is not cor-
rectly connected.
Switch off the electrical cabi-
net and check the connection
to the electricity grid
The demagnetization cycle is
not carried out correctly
Interferences affect the regu-
lar functioning of the control
unit.
Install a mains filter up-
stream to the control unit.
