SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section explains the error indications and corrective
actions for the Quick Response Slave (QRS) module.
ERROR INDICATIONS AND CORRECTIVE ACTION
You can obtain the status of the QRS through an INFI 90 oper-
ator 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 QRS status LED
states, error indications, probable causes and corrective
actions.
NOTE:
If the corrective actions in Table
do not correct a problem
with the QRS module, replace the slave module.
Master Module Errors
The Multi-Function Processor (MFP) performs status checks on
the QRS. An error will appear in the report function of an oper-
ator interface. Refer to the Product Instruction for the operator
interface you are using for an explanation of these reports.
