1.) Remove reference spacer a (accuracy: ± 0.1 mm)
2.) Loosen lock nut (SW 46) s .
3.) Unscrew adjusting screw (SW 22) d max. four turns.
4.) Carefully press apart the contact rails f of the corresponding thyristor.
5.) Remove thyristor disc g.
6.) Using a spatula, apply a thin layer of contact grease (Elektrolube
7.) Insert new thyristor disc. Make sure it is positioned correctly (polarity and terminals)! Connect firing cables.
8.) Screw in adjusting screw (M30x1.5) d until the reference gauge a has been reached.
9.) Firmly tighten s lock nut.
The position of the thyristor and its diameter may not be the same as in the diagram! After a thyristor defect, check the fuse indicators at the least.
