ON-LINE FAILURE
This part of the troubleshooting section covers failures that
occur while the FCS is on-line and how to troubleshoot those
failures. On-line failures are a result of hardware failure, loss
of input signal, bad quality or the input signal is outside of the
operating specifications. See Figure
shooting flowchart. Table
lists error messages, causes and
corrective action. For a listing of error messages on other oper-
ator interfaces (i.e., PCV) refer to the instruction manual for
those devices.
To correct an on-line failure:
1. Monitor the operator interface for error messages by check-
ing the module problem report.
2. Follow the corrective action in Table
that applies to the
error message.
3. If your operator interface is a configuration and tuning ter-
minal/module monitor Function Code 145 output block n + 3.
A 1 in function code 145 block output n + 3 indicates bad
quality while a 0 indicates good quality.
4. For bad quality, go the Table
, find bad quality in the
cause column, and follow the corrective action listed.
