LCD Screen
The LCD provides the user with a variety of useful information. The LCD has a real- time meter to display, in numeric fashion, the
following data:
•
Input Voltage and Frequency
•
Output Voltage and Frequency
•
Connected Load KVA and KW
•
Estimated runtime in the AC and DC mode Connected Load Capacity Bar
Graph Battery Capacity Bar Graph
The LCD will include dedicated icons for the following information:
•
AC Normal / AVR Mode (Boost: The AC Normal icon will flash) On Battery
•
Weak/Bad Battery
•
UPS-1000-Li-2 Fault
•
Site Wiring Fault
•
Overload
The LCD backlight will turn on when the UPS-1000-Li-2 is turned on. After approximately
20-seconds the backlight will turn off to conserve energy. When an event (alarm) occurs, such as going to the battery mode,
the backlight will turn on for approximately 20-seconds to alert the user that an event has occurred and then the back- light will
turn off. While the Scroll button is in use the backlight will remain on. Approximately 20-seconds after the Scroll button has
stopped being used the back- light will turn off to conserve energy.

Self-Test
The self-test feature is useful to verify the correct operation of the UPS-1000-Li-2 and the condition of the batteries. The start-
up and user invoked test are used to measure the
battery’
s capability to support the connected load. If the UPS-1000-Li-2 fails
one of these tests, one of the icons or the information displayed on the LCD will remain illuminated indicating the type of
problem.
NOTE:
The UPS-1000-Li-2 will automatically perform a self-test on start-up.

Alarms
ON BATTERY
When the UPS-1000-Li-2 is operating on the batteries, the AC normal icon will extinguish, the On-Battery icon will illuminate, the
LCD will display the estimated runtime remaining and the alarm will sound one beep every 10 seconds. Once the UPS-1000-
Li-2 returns to the normal AC mode, the alarm will stop, the On-Battery icon will extinguish and the AC normal icon will illuminate.
LOW BATTERY WARNING
When the batteries reach the predetermined level, the alarm will sound two beeps every five seconds, the Battery Bar Graph
will display the remaining battery capacity and the LCD will display error code E07. This information is to inform the user that
there is approximately two minutes of runtime remaining before the UPS-1000-Li-2 shuts down. This condition will continue until
either AC returns or the UPS-1000-Li-2
’s
self-protection circuit shuts the UPS-1000-Li-2 down to protect the battery from over
discharging.
WEAK/BAD BATTERY
The UPS-1000-Li-2 automatically tests the
battery’
s condition. If the battery is weak, bad or disconnected, the Weak/Bad Battery
icon will illuminate and the Battery Capacity Bar Graph will turn off and the alarm will sound three beeps every five minutes until
the battery is either reconnected or replaced. This alarm will be repeated until the batteries pass a self-test. It is recommended
that the UPS-1000-Li-2 be allowed to charge overnight before performing a battery test to confirm a Weak/Bad Battery
condition.
OVERLOAD
When the amount of load attached to the UPS-1000-Li-2 exceeds its power rating, the Overload icon will illuminate and the
alarm will sound continuously (AC and Battery modes). This alarm will remain on until the excess load is removed or the UPS-
1000-Li-2
’s
self-protection circuit shuts the UPS-1000-Li-2 down.
