Control Panel
The Expansion Unit Control Panel (Figure 2–2) contains three LED indicators,
a four-line by 20–character backlit LCD display, and four pushbuttons. The
pushbuttons enable the operator to navigate through the menu structure to
select and display operating modes, device status, diagnostic and maintenance
functions, device history and error statistics, and system configuration.
LED Indicators
The three LED indicators on the Control Panel are labeled
Ready
(green),
Alert
(yellow),
and
Fault
(red).
■
Ready
(
green) - lights when the system is ready to accept commands,
either from the Control Panel or from the host computer. The
Ready
indicator goes out when you enter the Menu Mode.
■
Alert
(yellow) - indicates that a fault or some other matter that requires
attention has occurred in one of the modules in the system. Line 2 of the
display blinks the number of the module where the fault has occurred.
The Control Panel of the indicated module may give a further indication
of the cause of the alert. Often, when the
Alert
LED is lit, a
Fault
LED
is lighted on one or more of the MiniLibrary Base Modules as well.
