Spent most of this afternoon troubleshooting the newly assembled maglev backing pump cart. Discovered that the Sentry isolation valve (redundant isolation) was faulty so it was removed for now. Also the 2-position Interlock selector switch was wired backwards etc... -> Cart is connected and operational and is pumping against a closed valve for tonight. The purge-air was decoupled and HAM6 blown down to a "slightly" positive pressure. The Kobelco compressor was also shut down.
We are set to begin pumping HAM6 tomorrow morning. Chandra R. has OKayd unattended pumping so we expect to be ready to switch over to the turbo by Wednesday.
We didn't start pumping tonight because there is some confusion about where to turn high volts off, particularly new squeezer components. M1300464 needs to be updated with clearer descriptions if VAC personnel are to verify HV off before pump down or vent.
