COMMENT ON Troubleshoot North Lianc LCW Pump Trip

15 hours 39 minutes ago
Log Number: 4530729Logbook(s): Body: 

EPAS PTW-11385 has been prepared for this work.

Technicians performed a visual inspection of the VFD cabinet and its cabling, as well as an inspection of the terminal box on the pump motor itself. All connections and cabling appeared in good condition and properly connected/tight. A megger test was also performed on the leads between the VFD cabinet and the pump motor and all passed with flying colors. Due to the accelerator being down for arc magnet flushing, we have opportunistically repowered the VFD drive and placed it back in service by switching the operating NL LCW pump.

C laser attenuator slipped, homed it, no further issues

Log Number: 4530693Logbook(s): Entry Makers: brukerBody: 

TLDR: C laser attenuator had lost its home; home/reset restored it. Root cause unknown.
Troubleshooting log follows in case it's useful to someone else later on.

First, two notes about how to interpret the data from the TMG test script:
1. The full-scale scope traces have a different DC offset than the low-scale ones (e.g., BS high-res).
