INTRODUCTION
This section explains the error indications and corrective
actions for the Controller Module (IMCOM03/04).
ERROR INDICATIONS AND CORRECTIVE ACTION
Obtain the status of the COM through an INFI 90 operator
interface (e.g. Operator Interface Station, Engineering Work
Station, Configuration and Tuning Terminal) or the front panel
module status LED indicator.
Status LED
The front panel status LED has three states to indicate normal
operation and error conditions. Table
lists the symptom
and recovery procedures for execute errors.
Controller Module Errors
The controller module performs its own status checks. An error
will appear in the report function of an operator interface. Refer
to the product instruction for the operator interface you are
using for an explanation of these reports.
NOTE: Refer to the product instruction for your configuration device
when referring to this table.
