Big blue wet benches Useable  20180814

20181015 – Connected the 3-phase supply to the left side – Alarm 1 is coming on so it is not running yet.

1 – I put in a new controller for the right bench and it allows for the bench to be used. The old controller might be ok, but I did not realize you had to power cycle the bench with the main breaker if the EPO is pressed. There is still an alarm going and I am not sure yet what is causing it.
2 – I started checking the controls to see if everything works – did not get very far, but there is running DIW and N2
3 – The aspirators are not working and this is very much likely because Bill has decided to run these to the new acid waste storage tank instead of the current one. To finish the new tank will take significant time and funds to get operational and with the current usage I do not see the point. I might be able to tee into the current tank, however I am not sure what has been done to turn off the aspirators.
4 – The left bath seems to have no power, but the breaks are not labelled to know where the power is going – luckily for me there is only one break currently off – however it did not turn on the left controller for the bench.
5 – The left bench is not connected at all for waste and this will mean breaking the lines on the 3rd floor to install tees and then running tubes up to the 4th floor to be connected.
