SF-PW Procedure

This is to determine the cause of why the FR-SF drive is not powering up and showing no LED display. 

  1. Remove SF-CA control board from FR drive.
  2. Turn on power to drive.
  3. Locate yellow/amber LED on power supply.
  4. If LED is on, then the problem with power is with the control board. If LED is off, then power supply is the problem.
