Viewing Diagnostics

The BCU operator display lists active diagnostics for most of the equip-
ment selected for viewing and editing at the display. Active diagnostics
provide information about the state or condition of the equipment that
could adversely affect its operating performance. Figure 22 shows the
presence of an active diagnostic for a piece of equipment.

The operator display can list three different types of active diagnostics:
Manual reset

• Automatic reset
• Informational warnings
For some equipment, a symbol is associated with each type of diagnostic
to aid you in identifying the types of information that are displayed on the
diagnostic screens (see Figure 23 on page 26). The diagnostics are listed
in chronological order with the most recent diagnostic listed first.
