During troubleshooting of various stages of relock this afternoon, we noticed the ETMx ESD looked "funny" so Richard headed out to EX this time in search of a cure. By "funny" we mean the 4 QUAD signals were the same sign as the DC - normally they are opposite. As well, when Richard got to the end station, he found the HV ON/OFF switch was being toggled (audible at the rack) repeatedly so he unplugged the Binary cable which stopped it. He toggled the HV ON/OFF a few times to see about clearing the sign issue. Then, after a round of conversation, we found the BIO L3 HI/LO VOLTAGE and HI VOLT DISCONNECT were in the OFF positions on the ETMx - this is an incorrect state for acquisition. So, I have written into the SAFE.snap to restore the ETMx to the HI Voltage state after a restart. AFter all of the rack manipulations and a correct set of MEDM switches were thrown, the ETMx ESD seems healthy. On with locking attempts.
