SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section explains the error indications and corrective
actions for the IMCIS12 and IMQRS12 modules.
ERROR INDICATIONS AND CORRECTIVE ACTION
Status of the CIS and QRS modules can be obtained through
an INFI 90 OPEN operator interface (e.g., Operator Interface
Station, Engineering Work Station, Configuration and Tuning
Terminal) or the front panel module status LED indicators.
When using an operator interface, check the control module
for good quality on output N+9 of function code (FC) 79; 0 =
good status, 1 = bad reference status, I/O failed to respond.
Status LED
The front panel status LED has three states to indicate normal
operation and error conditions. Table
5-1 lists status LED
states, error indications, probable causes and corrective
actions.
NOTE:
If the corrective actions in Table 5-1 do not correct a problem
with the CIS or QRS module, replace the module.
