3.3 Working Mode and transferring
Usually, the UPS should be set to work in AC mode, so it will transfer to battery
mode automatically without interruption when AC fails. When the UPS is overloaded,
it will transfer to bypass mode without interrupt. When the inverter is defective or
over temperature inside UPS, UPS will transfer to bypass mode if the bypass is
normal
3.3.1 Transfer to bypass if overload
When the load of the UPS is beyond normal range and lasts for the time set, it will
transfer to bypass mode and beeps twice every second. Then, the load is powered
by AC directly, at that time, please decrease the load immediately until the alarm is
elminated.UPS will start the inverter after 5 mins. In order to protect the load and
UPS, it is required to set the limitation times of transferring to bypass mode due to
overload in 1 hour. If it exceeds the limitation times set, the UPS will keep in bypass
mode.
3.3.2 Normal mode to battery mode
The UPS will go to battery mode if the AC is failed. The UPS will shut down
automatically if batteries are drained. When AC recovers, the UPS will start the
inverter automatically.
3.3.3 Go to Bypass mode due to over temperature
The temperature inside UPS may be high if ambient temperature is high or the
ventilation is poor, then the UPS will go to Bypass mode, fault indicator will be on
(red), the LCD will display that the inner temperature is high, long beeps will come. If
so, please cut off the input power of UPS, move objects that affecting the ventilation
far way from UPS if any or increase the distance between the UPS and the wall.
Wait until UPS temperature become normal, restart it.
3.3.4 Output short circuit
When the UPS output is in short circuit, UPS will cut off the output, fault indictor will
be on (red), the LCD will display that output is short circuit, long beeps come. If so,
please disconnect the short circuit load, cut off the UPS input power and wait for
10mins, UPS will shut down automatically or press the off button to shut down in
after 10s. Before restarting the UPS, please make sure that the short circuit problem
has been solved
