Series-C I/O modules are constructed to support normal field failures, wiring errors and conditions such as a shorted wire. All Series-C IOTAs contain at least one fuse that provides protection for catastrophic errors in the IOTA, IOM and other elements of the Series-C system. In normal operation as well as many abnormal operations, the fuse element should not blow.

5.4 Monitoring Your Recorder
Introduction
Besides the historical chart record, you can monitor the recorder’s indicators and displays to get an
instantaneous view of various process conditions and of the control loop status.
Diagnostic error messages signal detection of malfunctions in certain internally monitored data. Alarm and
tuning messages indicate alarms in effect and control loops being tuned.
Operator interface
The indicators and displays on the operator interface let you see what is happening to your process and how
the recorder is responding.
