FB2100/FB2200 Flow Computer CPU Enclosure & Electronics Field Replacement Guide
Replacing the CPU Enclosure & Electronics
You can replace the CPU enclosure and its individual boards in the field provided that the
replacement has the exact same part number and version.
There is considerable overlap between the different field replacement procedures for the items
covered in this guide. This guide presents several discrete tasks which are used, and then
references them in procedures as they are needed.
Restriction
Hazardous area approvals require that any part replaced in the field be the exact same part ("like-
for-like"). Upgrading or substituting different parts violates hazardous area certification.
