11.6 General troubleshooting and diagnostics
information
The Rosemount
™
CT5100(Ex) is specifically designed to run unattended indefinitely, to
automatically resolve system issues, and to recover from power failures and return to a
normal working state. This troubleshooting guide is intended to assist maintenance
personnel when the analyzer has not appeared to be working normally for a period of
more than five minutes. If the procedures given in this section fail to return the analyzer to
normal operation or do not identify a fault, notify your service agent for further assistance.

DIAGNOSTICS
on the Main Menu will open the Diagnostics Menu ( Figure 11-8 ).
The Diagnostics Menu lists those main components of the Rosemount CT5100(Ex) where

components.
