[Dsg-rich] Fwd: RICH HV/LV board interlock testing

[Valery Kubarovsky]

Hi Tyler, 
Please find below the Chist's reply about the status of the LV/HV mainframe and modules. 
The mainframe will come hopefully this week. Is it OK with your plans? 

Please reply to the Christ's questions concerning your interlock system. 
Thanks, 
Valery

Hi Valery, 

We have received the CAEN HV modules and a few of the LV modules. 

The new CAEN mainframe will be delivered this week.(hopefully). We will fabricate a LV cable set including the sense line that will ultimately be used in the Hall. This cable set will provide 
LV power for thirty-two(32) 'tiles' and will be the length determined by Bob Miller. 

As soon as we receive the mainframe, we can move it to the EEL clean room for initial testing. How does the cRIO hardware interlock system 
connect/control the HV, LV modules? Is it simply a closure to the CAEN mainframe CPU module(A4528) front panel interlock input?

Chris, 
DSG wants to test RICH HV and LV interlock. 
Could we install everything that we have in the EEL building clean room? 
Regards, 
Valery

Hello Valery, 

We need to test the interlock enable ability of RICH HV and LV boards to be able to fully complete the cRIO-based hardware interlock system. 

Marco Contalbrigo mentioned that the power supplies would be moved soon to start installing the electronics on the electronic panel. 

Could we install all HV and LV boards in the power supply mainframe to be able to test the interlock enable functions? 

Best regards, 
Tyler
