HRC Command Sequences

HRC-S MCP HV On - SCS #93

Description:

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.

Cautions/Restrictions:

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"
