Figure 3-2. Operator Interface Showing Isolate Acknowledgement
After the acknowledgement, the list of Faults or Isolates is displayed, with the earliest Fault or
Isolate at the top of the list.
Most faults automatically clear from the system when the problem causing the fault (wiring,
device, etc.) has been fixed.
Some faults, such as open circuit faults on IDNet communications lines, latch until they are
reset manually or cleared by pressing the <SYSTEM RESET> key once the fault condition
has been fixed.
