Status
What you can do on the Status Screen
The Status screen allows you to see at a glance the operating and internal status of the SVI II
ESD. The screen is divided into a series of tabs that provide status, alarm, and fault information in
a graphical form for all aspects of the SIS (Safety Instrumented System).
Each alarm condition is color coded according to the criticality of the alarm:
 Blue = low
 Yellow = Medium (error conditions that can occur in normal operation, not faults, that
may presently exist or have historically existed)
 Red = High (indicates a fault)
 Green indicates no faults
On the Status screen you can reset the Current Faults or All Faults (Current and Historical). You
can also select and clear an individual fault.
The window has selectable tabs that display the associated parameters for each tab when
selected.
When you are on the Active Faults tab the current active faults appears (Figure 307). The status
codes are then partitioned into their respective SVI II ESD functional areas.
