Initial HRC-I MCP HV On
Description:
This procedure should be followed the first time the HRC-I MCP HV
power supply is turned on during OAC. First, the stored command
sequence that protects the HRC MCPs in the event of a high radiation
environment (85) is enabled. Then, the three protected stored
command sequences for the HRC-S MCP HV (SCS 88, 90, and 93) and for
the HRC dither control (SCS 91) are each disabled as necessary. The
HRC-I MCP HV ramp-up SCS (89) is disabled and the ramp-down SCS (87)
is enabled. Finally, the HRC-I MCP HV turn-on SCS (92) is enabled and
activated.
Cautions/Restrictions:
This procedure should not be executed until the the HRC detector
housing door has been open for 24 hours.
