U1 – potentiometer for setting the clamping force level
(output voltage regulation)
PRG – program selection switch
MAG – green illuminated button to start magnetization
DEM – red illuminated button to start demagnetizationDEM – red illuminated button to start demagnetization
Recommended operations before clamping workpieces:
- Clean the workpieces and the surface of the electromagnetic chuck.
- Place the workpieces on the electromagnet over the two poles of the electromagnetic chuck.
Magnetization – CLAMPING
- Press and hold the red illuminated DEM button for at minimum 0.25 seconds.
- During the demagnetization cycle the red button is flashing slowly – the safety contact RELAY RE1 is open.
- Complete demagnetization cycle is indicated by a continuous lighting of the red button.
Demagnetization – RELEASE
- Press and hold the red illuminated DEM button for at minimum 0.25 seconds.
- During the demagnetization cycle the red button is flashing slowly – the safety contact RELAY RE1 is open.
- Complete demagnetization cycle is indicated by a continuous lighting of the red button.
