SECTION 2
2.0 BASIC OPERATION
The MODEL 7800 offers 3 graphic screens for viewing monitored data and a Set-Up
menu screen for operator interface to configuration menus. They are shown below in
Figure 2.0. The Bar Graphs screen allows viewing of all active channels simultaneously.
The Trend screen displays a 24 hour trend one channel at a time. The Combination
screen displays a bar graph, large engineering units and a 30 minute trend one channel at
a time. Input channels may be displayed in sequence with the UP/DOWN keys. The
NEXT key switches between the 3 graphic data screens. When MODEL 7800 power is
applied, the graphic LCD returns to the screen active when power was last removed.
Setup menus are entered by pressing EDIT from any data screen, and scrolling to the
desired menu using the UP/DOWN keys. Pressing EDIT again enters the selected
menu’s tree of variables. This Setup mode may be exited manually by pressing NEXT,
or automatically when no keys are pressed for 5 minutes. Alarm relays and front panel
alarm LED indicators remain active during the Setup mode. An AUTHORIZE menu
offers a password feature to prevent tampering with MODEL 7800 parameters.
