 Battery Test Mode

In this mode, the UPS will stop the AC/DC section and discharge the battery

while mains input is normal. If the controller found the battery is error, it will

transfer back to line mode immediately, and warning by display to see whether

the battery needs to be replaced. The battery test mode could be trigged in line

mode by pressing the button or by the communication command.

The LCD display in battery test mode is same as the battery mode, The "TEST"

string indicates the UPS is working in the battery test mode.

 ECO Mode

It is also called high efficiency mode. In ECO mode, on LCD display, the mode

sting is "ECO".

After the UPS is turned on, the power used by the load is supplied from the utility

power via internal filter while the utility power is in normal range, so the high

efficiency could be gained in the ECO mode. Once the mains is loss or abnormal,

the UPS would transfer to battery mode and the load is supplied continuously by

the battery.

1) It could be enabled through the LCD setting or the software (WinPower).

2) It is attention that the transfer time of UPS output from ECO mode to battery

mode is less than 10ms. It is suggested to take account of applications for some

sensitive load.

 EPO (Emergency Power Off)

It is also called RPO (Remote Power Off). Turn off the EPO switch could occur

RPO .On LCD display, the mode string is "EPO".

It is a special status in which the UPS would shut the output off and alarm. The

UPS could not be turned off by pressing OFF-Button on the panel, only after

releasing EPO status by connecting the EPO switch.

 Converter Mode

CVCF (Constant Voltage Constant Frequency) which is also called converter

mode, the UPS would free run with fixed output frequency (50Hz or 60Hz) in

converter mode. Once the mains is loss or abnormal, the UPS would transfer to

battery mode and the load is supplied continuously by the battery.

1) It could be enabled through the LCD setting or the software (WinPower).

2) The load should be derating to 60% in converter mode.

 Fault Mode

If the UPS generates some internal failure and have to stop its inverter, it will go

into fault mode and alarm by display and buzzer.

In fault mode, the loads have the risk of power loss because the output will come

from the bypass after UPS fault.

In fault mode such as BUS fault etc., the corresponding fault string would be

shown to indicate the operating mode of the UPS. For example "SHOR" would

be shown when the load or the UPS output is short. The LCD display is shown in

the following diagram.
