SECTION 2
2.0 BASIC OPERATION
The SafeGuard Controller 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 SafeGuard 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 the SafeGuard Controller’s
parameters.
