OVERLOAD:
If an overload occurs, the OVERLOAD LED will light and a continuous
beep will be heard. Under this condition, check the load conn
ected to
the UPS.
BUCK/BOOST:
If the UPS encounters a high utility voltage, the function of the
buck is to automatically curtail this voltage to a normal level. In the case
that the UPS should come upon a low utility voltage, the boost will raise
the voltage to a normal level. These two functions are represented by
their respective LED on the front panel.
BATTERY REPLACE:
This function is to alert users of the need to replace the batteries. When
the microprocessor in the UPS detects battery fault, the UPS alarm will
give out three beeps. Each beep lasts for 0.5 seconds and interrupted
by an interval of 0.5 seconds. After the initial three beeps, the alarm will
continue to sound every one hour.
Operation (continued)
