 +  * **Troubleshooting**: if a power supply cannot be turned on from PanelMate, check that the power supply module is ON. The modules for all S800 magnets are located in the S3 vault on the middle level under the stairs to the top level (see figure below). If all the modules seem to be running properly, but the problem persists, contact the operators in Control Room, ext. 305.

        * Check the currents in the Spectrograph dipoles by looking at the EPICS channels I265DS and I269DS. This can be done e.g. by clicking the button **Details** in segment 8 of the S800 Barney page (see figure below)        * Check the currents in the Spectrograph dipoles by looking at the EPICS channels I265DS and I269DS.
