Subject: Sphenix PS

 

Hello All;

 

 

 

We were able to turn the Sphenix PS to the On State and ran it open loop in test mode. The output had one SCR out of 12 that was half the size as the rest.

We decided to change one of the Firing Board at a time on the first try all SCR were firing correctly.

 

No problem with the 480VAC input Phase. It is good to go.

 

CAS Tech will stay late tonight and come in tomorrow to have more hours running, also they will start to check readbacks to the PET Page and PLC

 

 

Thanks
