Operation (continued)
OVERLOAD:
If an overload occurs, the OVERLOAD LED will light and a continuous beep will be heard. Under this condition, check the load connected to
En
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.
