Hi Brian,

Stepan mentioned that magnet ramped down and the He level went down as well...
Could you please check if that dumped or ramped down...The coil temp seems ~20K.

Regards
Probir

Suggest to ramp both magnets to zero if not done yet…!

It looks like there is an issue with the DBox PLC. I can't go online with it with RSLogix and it isn't responding to pings.

According to the solenoid's SOE module the LHe level was the first to trip off.

Since I can't do anything remotely will need to have an access to go see what is causing the problem. Will probably be at least 15:45 until I can come in.

Hello Nick and Probir,

I got a call from counting room that there is a torus PLC alarm. I do not know who is responsible for it. But we need someone to look at.

Thanks,
Stepan
