SYSTEM SCREEN
The System screen shown below (Figure 8-1) displays all active channels at once. It is
capable of displaying 16, 32, 48 or 64 channels depending on the controller’s
configuration. This screen, very similar to the Main Data screen, displays measurement
name and uses a colored cells that flash with new alarms to indicate alarm conditions.
Once the alarms have been acknowledged by an operator the cell will remain the
appropriate color but will stop flashing, showing the alarm has been acknowledged.
The five standard relays states are shown at the bottom of the screen. The boxes
duplicate the LED behavior as seen when looking at the unit. A flashing box indicates an
unacknowledged relay, a red box indicates an energized (de-energized for failsafe) relay.
While in the System screen, use the mouse to click on any cell to go directly to that
channel’s individual data screens. The unused channels are grayed out when turned off.
Viewing only channels belonging to a certain zone can be enabled using the zone drop
down box. Selecting a zone will cause channels belonging to other zones to dim.
The System screen is updated automatically every 15 seconds.
