Battery mode / battery self test mode operation process
5.6 ECO mode
LED indicator in ECO mode is as shown in the figure below: the inverter. LED
indicator (green) is illuminated and bypass LED indicator (yellow) is illuminated,
meanwhile LCD display ECO characters.
When bypass input meets ECO input range and ECO function come to use, the UPS
works in ECO mode. At this time bypass supply power to the load, meanwhile
rectification, boosting and inverter work normally, and the charger charges the
batteries. When bypass input is out of ECO range, the UPS transfers to mains
power/ battery mode operating.
If bypass input is beyond ECO range for five times within 1 hour, the UPS operates
time after time from ECO mode to mains power mode, the UPS will automatically
operate in mains power mode and close ECO function.
Note:
When use ECO mode and ECO transfers to inverter, the output probably
break off 20 ms. For those loads which require strict transfer time, be cautious to
choose whether start ECO mode or not. Please contact with supplier or after sales
staff if need to set economy control operation.
