No P2N is loaded. Testing the power supplies.

In the past few days, the ITS has been reconfigured for P2N operation:

•  The two ATTS PS were moved to the ITS rack, one on top of the TGHT and the other instead of the COIL
• AC rewiring was necessary since the breakers were not connected to the wires. Marshall was on it and re-connected
• Ray has configured the ATTS PLC to be compatible with P2N operation in ITS
• The controls cables to the MASTER and SLAVE supplies have been configured: the cables come from the front of the PS rack, so we could close the back and top cage if we wanted. One control cable was connected to the relay to send the proper ENABLE signal only when the ITS vacuum and water flow are OK
• DC cables re-routed for P2N parallel operation:
  MASTER+ = D
  MASTER- = C
  SLAVE+ = E,G 
  SLAVE- = F,H
  TBHT+ = A
  TBHT- = B
