Check the group cathodes
The group cathode for the water-cooled resistor is located on the
rear side of the RF output stage. Residual matter resulting from
worn sacrificial anodes or corrosion can form on the inside of the
seal caps and must be removed regularly.

Danger
Lethal voltage at seal caps when the earthing bracket plate is
removed.
Do not, under any circumstances, remove the earthing bracket
plate. When operating the laser unit without bracket plates, there is
a resulting DC potential of 500 V at the seal caps.

•
Switch off cooling water.
•
Open rear door of generator.
•
Unscrew both seal caps on water-cooled resistor. The seal
caps are the group cathodes.
•
Remove residual corrosion matter which might be present in
the group cathodes and in the housing.
•
Screw group cathodes down.
•
Inspect the screw joints for tightness.
