* Go to page 7 and select the steering magnets: **I170DH, I197DH, I231DH**. Note that some of the power supplies are connected to more than one steering magnet. If necessary, disable the steering magnet of the other line and enable the correct one. | * Go to page 7 and select the steering magnets: **I170DH, I197DH, I231DH**.
