COMMENT ON Troubleshoot ARC5A Box Supply Trip

Log Number: 3912680Logbook(s): Body: 

Late Entry: Earlier today, the breakers for Arc 5 and RSEP8 were swapped. The current trip limit was lowered to 800A and the LD (Long Delay) Fault was increased to 5 seconds from 2 seconds for RESP8 (formerly ARC 5). Both SAM 1 and NAM 1 were restored successfully. The box supplies in both buildings were powered up, settings restored and cycled successfully.

OTF vs hand spun ODH screens

Log Number: 3912662Logbook(s): Entry Makers: michaelmBody: 

OTF screens do not show the purple indicator which denotes the head is bypassed. These bits are set by ABIL.

LERF heads for example:
OM206cal
OM228cal

Not sure if HLA or SSG owns the OTF generators for these.

PD UPDATE: breaker failed in new location

Log Number: 3912655Logbook(s): Tags: Entry Makers: beneschBody: 

The breaker which tripped four times when supplying the Arc 5 power supply was swapped with the same style of breaker supplying RSEP8A this afternoon. It just tripped in its new location. Beam can only be supplied to Hall B until the breaker is replaced. The distributor and manufacturer cannot provide information until Monday. FML SME hazarded Wednesday as earliest possible fix and could not provide a not-to-exceed date. Pass three beam is accessible if it's of any use to anyone.
