HRC Command Sequences



This sequence is used to turn on the HRC-S MCP HV power supply. This sequence disables the current limiter, sets the HV command levels to zero (first top then bottom), turns the HRC-S 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-I MCP HVPS must be off
  2. The HRC is configured to be using the HRC-S with "Set HRC-S Unique Defaults"

Delta-Time Command Mnemonic Description Cmd Field Mnemonic Data Parameter Telemetry Verifier Expected Value Notes

00:00:01.000 2SPTBHV Set spectroscopy bottom MCP HV step to 0 2SPTBHV2 0 2SPBPAST 0 sd0300
