OP03 Procedures | op03: |
This sequence uses serial digital commands to shut off each of the HV power supplies, HRC-S, HRC-I, PMT 1, and PMT 2 (only one of HRC-I or HRC-S and one of PMT 1 or PMT 2 should be on). It then sends high level pulse commands to switch off both the A and B side +5V power supplies (again only one of these should be on).
This command sequence is based on the HRC EGSE scripts allhvoff.cmd and 5voff.cmd
