Switches
The Power switch turns the unit on and off. To start the UPS when AC
power is not available, press and hold the DC Start button for about 5
seconds.
The Test/Alarm Silence Button
The Test/Alarm Silence button allows you to run the quick self test when
the UPS is in the normal mode. If an error was detected and you wish to
reset the error display, press the Test/Alarm Silence button.
LCD FRONT PANEL
The XRT1000 through XRT2000 units have a 32 character LCD display,
three push buttons, and the Power On and DC Start switches. (Both 120
and 220 VAC versions)
The Power On and DC Start switch operate the same as the XRT600.
The LCD display will step you through all of the functions of the UPS.
The top line of the display indicates the parameter and function, and the
bottom line displays the function of the three buttons below the display.
Startup
When the unit is first turned on, the self test is executed and the
message “Startup Diagnostics” is displayed. After successful completion
of the self test, the message “MINUTEMAN Model XRTxxxx” will be
displayed for 5 seconds. The “On-Line xxx% Load” menu then appears. If
the self test was not successful, or if an error event occurred the last
time the UPS was powered on, then the message “Error Detected” will
be shown on the top line of the display and the actual error message is
shown on the second line (see the Initial Error Message list in the
TROUBLESHOOTING section). Pressing any button will clear the
message and allow the unit to power up and show one of two messages.
