7 Troubleshooting
7.1 Overview
Troubleshooting involves responding to error messages, primarily displayed by the MC Toolkit. Error
messages that may occur on the Transmitter’s local display are fairly self-explanatory and intuitive.
However, this section covers the diagnostic messages that indicate critical conditions. Other than the
critical conditions, additional detail is not provided. If you require assistance, contact your distributor
or Honeywell Technical Support. All other messages are covered by the MC Toolkit Users’ Manual.
7.2 Critical Diagnostics Screens
When a Critical Diagnostic is present in the Transmitter, the Advanced Display will show one or
more of the screens pictured in Figure 28. These screens will be inserted into the normal screen
rotation and displayed between the user-defined operator screens. A description of the diagnostic
conditions is given Table 20, along with suggested actions for resolving the problem.
