Bias power OFF, SIP ion pump power back ON. NIM crate powered off. Motors pi and nnrpi1 still on for remote access. Compressed air off, water off. Fee relay power off and power cable disconnected. Motors box off. Safety pin for motors reinserted. Checked cable harnesses at cryring. 2 good short sections found and left with boxes in cryring. 2 damaged long sections (bad pin and broken ceramic) taken to repair in Edinburgh.
