SRVO-229: SDI fuse blown (FUSE2)

FUSE2 on the main board - protecting the +24V peripheral device interface - has blown.

What it means

FUSE2 on the main board - protecting the +24V peripheral device interface - has blown. Same disease as SRVO-220's FUSE1, adjacent circuit.

Common causes

Ranked by what technicians most often find, most likely first.

  1. 24SDI shorted to 0V through the peripheral device cable.
  2. Main board fault.

How to fix it

  1. With the controller de-energized and locked out, inspect the peripheral device cable and replace it if suspect.
  2. Take an image backup with the controller powered, then de-energize and apply lockout/tagout again before replacing the main board.
