BATTERY REPLACE: This LED function is to alert user that
the batteries should be replaced. When the microprocessor in
the UPS detects a battery fault, the buzzer beep 0.1 second
every 2 seconds. (Shown as Figure 3-10)
BATTERY LOW: This function is to inform user the remaining
power capacity of the batteries. When batteries reach a low
level condition, the UPS alarm will beep half second every 1.5
seconds until running out of battery capacity. (Shown as Figure
3-11)
SHORT CIRCUIT: When the output of the UPS shorts in
“ON-LINE mode” or “ON-BATTERY mode”, the UPS will shut
down (without output voltage). As soon as the short circuit is
happened, the fault LED will light on and the UPS alarm will
sound continuously. When remove short circuit, the UPS output
will recover. If short circuit is happened in “BYPASS mode”,
the UPS will protect itself by tripping the input breaker and shut
down. (Shown as Figure 3-12)
3-12 De-rating Power
In the range of 130Vac to 160Vac, the UPS load capacity will decrease. This
function provides a wider operating power voltage range.
