SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section explains the error indications and corrective
actions for the Quick Response Controller (IMQRC01).
ERROR INDICATIONS AND CORRECTIVE ACTION
The status of the QRC can be obtained through an operator
interface or the front panel LED. An operator interface can also
be used to verify the input values received by the QRC from
other modules and on-board inputs.
QUICK RESPONSE CONTROLLER STATUS INDICATOR
The QRC has a single status LED. The status LED shows either
normal operating conditions or error conditions. Table
summarizes the LED states, probable causes and corrective
actions to take for the different indications. LED states that
indicate an error condition are:
Red
A red LED indicates a fatal error has occurred. With this type
of error, the module halts all operation and does not communi-
cate over the module bus. Without communication over the
module bus, the module status bytes cannot be accessed. The
module should be replaced with a configured backup.
