Operation
Indicates danger for persons with a cardiac pacemaker.
Operate device only in enclosed premises accessible only by authorised personell.
Connection and disconnection of the coil module only with main switch off.
•
High current flow during demagnetization pulse
•
Physical contact to energised parts can be lethal
•
Disconnection during pulse results in damaging of the connector
•
Wait 10 minutes for capacitor discharge before opening
Interruption of power supply during demagnetization pulse leads to immediate pulse
disruption.
•
Parts in the vicinity of the coil are magnetised and need to be demagnetised
once more
•
Frequent interruption accelerates electric wear
Cycle times below specification may lead to overheating of the coil. Pulse triggering
is blocked („Ready“ indicator dark, no „Ready“ signal). After cooldown pulse
triggering is enabled again.
Danger of burns at power connectors. Poor coupling of conductors can lead to
heating of connectors and conductors. Physical contact can lead to burns.
6.1 Operation mode
The machine can be operated manually or automated.
•
Manual operation via control panel
•
Automated operation via
D-Sub15 Control Interface
6.1.1 Manual operation
•
Place object in coil
•
Trigger demagnetization pulse by pushing
Start
button
•
Remove object after completion of demagnetization pulse (
Active lamp
goes out) and
measure residual magnetism regard to measurement process definitions
