  • The power supplier controller, referred to by Glassman as thee "remote unit" is an older version of the ones at UITF and CEBAF. All of them have a J1 I/O and a J2 remote interface used for the PSS. UITF and CEBAF have in addition a terminal block in the back of the controller, where the output of the interlock chassis sends the 24 VDC for enabling HV. However, the GTS controller does not have this terminal block. Instead, HV enable comes through the J1 connector once all the interlocks have been satisfied. This is what the interlock chassis did, but is is a very different interface than that in the UITF and CEBAF.
