2.6.3 Power Management Display (PMD)
Working in conjunction with the
UP
,
DOWN
and
ENTER
buttons, the LCD screen at the centre of the power management
display presents a range of selectable menus which allows the user to operate the UPS and monitor its performance – the
menu tree is shown in Figure 2.10.
Status screens
During normal operation the LCD displays a default UPS status screen similar to those shown below. From the status
screen the user can access the ‘top level’ menu by pressing the
UP
or
DOWN
button; and then further navigate through the
nested sub-menus using the
UP
or
DOWN
buttons to scroll, and the
ENTER
button to make a selection.
On the right hand side of the LCD-Display is a three digit indicator which shows the module’s position in a multi-module
system (maximum number of modules is 10).
Top level menu
The following sub-menus can be accessed from the top level menu:
EVENT
LOG
– The event log stores the last 64 UPS events in date/time stamp order. These include both ‘fault’ events,
such as [

].
MEASUREMENTS
– This sub menu provides access to a range of input, output and battery parameter metering.
COMMANDS
