HRC Command Sequences



This sequence is used to turn on the HRC-I MCP HV power supply. This sequence disables the current limiter, sets the HV command levels to zero (first top then bottom), turns the HRC-I MCP HVPS on, and finally re-enables the current limiter.


This command sequence should only be used if the following conditions are met:
  1. The HRC-S MCP HVPS must be off
  2. The HRC is configured to be using the HRC-I with "Set HRC-I Unique Defaults"

Delta-Time Command Mnemonic Description Cmd Field Mnemonic Data Parameter Telemetry Verifier Expected Value Notes
00:00:01.000 2IMCLDS Imaging HVPS current limit disable     2IMCLST DISA sd0c00
00:00:01.000 2IMTTHV Set imaging top MCP HV step to 0 2IMTTHV2 0 2IMTPAST 0 sd0a00
00:00:01.000 2IMTBHV Set imaging bottom MCP HV step to 0 2IMTBHV2 0 2IMBPAST 0 sd0b00
00:00:01.000 2IMHVON Imaging MCP HVPS On     2IMONST ON sd0901
00:00:02.000 2IMCLEN Imaging HVPS current limit enable     2IMCLST ENAB sd0c01
