I need to hookup +/- 24 V supplies to the OMC whitening/dewhitening boxes that have been added to 1X2.
There are trailing +24V fuse slots, so I will extend that row to leave the same number of slots open.
While removing one +24V wire to add to the daisy chain, I let the wire brush an exposed conductor on the ground side, causing a spark. FSS_PCDRIVE and FSS_FAST are at different levels than before this spark. The 24V sorensens have the same currents as before according to the labels. Gautam advised me to remove the final fuse in the daisy chain before adding additional links.
gautam: we peeled off some outdated labels from the Sorensens in 1X1 such that each unit now has only 1 label visible reflecting the voltage and current. Aaron will post a photo after his work. |
