3. Product introduction

3.1 Functions description

 This product is a true online double-conversion UPS (Uninterruptible

Power Supply). It provides perfect protection for critical load such as computer system. It can eliminate almost all mains power disturbances. The input AC current can be corrected to a wave following the mains voltage, so it is a high power factor system.

Through the PWM control technology, the output voltage can be a pure & stable sine wave AC voltage.

 When the mains input become abnormal, the controller will stop the

AC/DC and start the DC/DC section immediately to make sure the

DC/AC (inverter) section can continue to work. After the mains input come back to normal range, the DC/DC will be stopped and the

AC/DC works again. So the load is always power-supplied through inverter without any interrupt if the UPS is turned on.

 The UPS also provides an internal bypass way to make the load can be powered by mains input directly when the UPS is off or failed.

 The UPS have an internal charger for batteries, the charger will charge the batteries when the mains is in a reasonable range on

“bypass mode” or “line mode”.

9

3.2 Mode description

The different strings could be displayed on the LCD screen corresponding to their own operating modes, and they are illustrated as the following table. At any time, only one normal operating string or fault string is presented. But the warning, even several warnings could appear in a certain normal operating mode at one time. And the normal operating mode string and the warning string would be shown circularly. Once one fault is come forth, then all previous warnings would not be shown again but only the fault string is presented.

Normal operating mode

LINE bATT

TEST

ECO ECO mode

 No output mode

The LCD display in No output mode is shown in the following diagram. The information about the utility power, the battery level, the UPS output and the load level could be displayed. The “STbY” string indicates the UPS is working in the No output mode.

10

■

The No output mode

 Bypass mode

Bypass mode means that the UPS provides the power through the internal bypass way to load directly without any regulation. If the controller detects the mains is abnormal, it will shut off the output to protect the load. The bypass voltage/frequency range and default output status (on/off) could be set by communication software.

The LCD display in bypass mode is shown in the following diagram. The information about the utility power, the battery level, the UPS output and the load level could be displayed. The UPS will beep once every 2 minutes in bypass mode. The “bYPA” string indicates the UPS is working in the bypass mode.

■

The Bypass mode

 Line mode

Line mode means that the mains input is rectified/converted by the

11

AC/DC section and then inverted to stable output by DC/AC section.

In line mode, the output is clean and good to the loads. If the mains get abnormal, the UPS will transfer to battery mode without interrupt.

The LCD display in Line mode is shown in the following diagram. The information about the utility power, the battery level, the UPS output and the load level could be displayed. The “LINE” string indicates the UPS is working in Line mode.

■

The Line mode

 Battery mode

Battery mode means that the battery power goes through the DC/DC section to the inverter (DC/AC) and get a stable backup output when the mains input is not usable. If the mains input recovered, the UPS will transfer to line mode without interrupt.

The LCD display in battery mode is shown in the following diagram. The information about the utility power, the battery level, the UPS output and the load level could be displayed. The “bATT” string indicates the UPS is working in the battery mode.

When the UPS is running in battery mode, the buzzer beeps once every

4 seconds. If the “ON” button on the front panel is pressed for more than

1 second again, the buzzer will stop beeping (in silence mode). Press the “ON” button once again for more than 1 second to resume the alarm function.

12

■

The Battery mode



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

2) It is attention that the transfer time of UPS output from ECO mode to battery mode is less than 10ms.

The LCD display in ECO mode is same as the Bypass mode, The

“ECO” string indicates the UPS is working in the ECO mode.

13

 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.

 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, and the background light become red. For example “SHOR” would be shown when the load or the UPS output is short. The LCD display is shown in the following diagram.

“STbY”.

Note 2: In bypass mode, the load is not protected. You should go on to the next step to turn on the UPS for protecting your load.

3) Press the on-button of the UPS front panel continuously for more than 1 second. The buzzer will beep once. After a few seconds, the UPS will be turned on to the normal mode (line mode) and output the spec voltage.

4) After the UPS is turned on to line mode normally. There is no beep of buzzer.

Note: If the UPS is shutdown in battery mode automatically, when the mains power returned to the input, the UPS will start up and switch to line mode automatically.

5.2 Start the UPS with battery (DC source) only

This UPS can be started with DC source (battery) without AC source.

1) If the UPS is a long back up time model with external battery banks, please switch on the battery breaker first.

2) Press the on-button of the UPS front panel continuously for more than 1 second. The buzzer will beep once. After a few seconds, the UPS will be turned on to the battery mode and output the spec voltage.

3) After the UPS is turned on to battery mode normally. The buzzer will beep according to the battery level.

26

5.3 Connect loads to UPS

After the UPS is turned on, you can switch on the loads.

1) It is recommended to switch on the load one by one. The Load level

grids

will indicate the load capacity in line mode.

2) If it is necessary to connect the inductance load such as a printer to the UPS, the start-up power should be considered for calculating the capacity of the UPS, because the power consumption is too big when this kind of load is started.

3) If the UPS is overloaded, all the Load level

grids

will display, display “OVLd ”and “LINE” in turns for 2 seconds, and the buzzer will beep twice every second for alarming.

4) If the UPS is overloaded, some loads must be switched off or decreased immediately. It is recommend that the total loads connected to the UPS had better be less than 80% of its nominal power capacity to prevent the overload happen at the transient time, and it will make your system more safe.

5) If the overload time is over spec in line mode, the UPS will transfer to bypass, after the overload disappears, it will return to line mode. If the overload time is over spec in battery mode, the

UPS will cut off the output and then shutdown according battery level.

5.4 Charge the batteries

1) After the UPS is connected to normal mains, the charger will work and charge the batteries automatically in bypass mode or line mode.

2) Suggest charging the batteries for 10 hours before use.

Otherwise the backup time may be less than the standard value.

5.5 Discharge the batteries

1) When the UPS is in battery mode, the buzzer will beep according to different battery level. If the battery voltage drops to

27

the alarming level, the buzzer will beep hurry (once every sec) to remind the user that the battery is low level and the UPS will be shutdown automatically soon. The user could switch off some non-critical loads to avoid the shutdown alarming and prolong the backup time. If have no more load to be switched off at that time, you have to shut down all loads as soon as possible to protect the loads or save data. Otherwise there is the risk of data loss or load failure.

2) In battery mode if the user doesn’t like the buzzer noise, the beep could be muted by press the on-button.

3) The backup time of the long backup time model is dependent on the external battery capacity except the load capacity mainly.

4) The backup time may vary from different environment temperature and load type.

5.6 Test the batteries

1) If you need to check the battery level or aging status when the

UPS is running on normal mode (line mode), you could press the on-button for more than 1 second to let the UPS transfer to battery test mode.

2) The battery test could be performed by the command from monitoring software through the communication port.

3) If the UPS enter the battery test mode, the display and buzzer indication will be same as the battery mode except that the mode displays “TEST”. So you can check the battery level at this mode.

5.7 Turn off the UPS with mains (AC source)

1) Firstly turn off the UPS (inverter) to bypass mode, please press the off-button continuously for more than 1 second.

2) After you press the off-button, the buzzer will beep once. Then the panel will display the bypass mode or standby mode.

Note 1: If the UPS have been set to enable the bypass output, the output socket will have voltage from mains directly after you turn off the UPS (inverter) to bypass mode.

Note 2: Because there is risk of power loss for the loads if you turn off the UPS to bypass mode, please make sure the loads are prepared for your operation.

28

3) If you want to turn off the output of UPS and shut down the UPS completely, you have to cut off the mains input of UPS.

Note: please make sure all the loads are prepared or turned off for your operation before you shut down the UPS system.

4) After you cut off the mains input of UPS to shut down. After a few seconds, the UPS will be shut down completely and the LCD extinguish.

5.8 Turn off the UPS with battery (DC source) only

1) To turn off the UPS in battery mode, please press the off-button continuously for more than 1 second.

2) After you press the button, the buzzer will beep once. After a few seconds, the UPS will be shut down completely and the LCD extinguish.

Note: please make sure all the loads are prepared or turned off for your operation before you shut down the UPS system.

5.9 Mute the buzzer

If the alarm is too annoying in battery mode, you may press on- button continuously for more than 1 second to clear it. Moreover, the alarm will be enabled when the battery is low to remind you to shut down the load soon.

If the alarm is too annoying in bypass mode, you may press off-button continuously for more than 1 second to clear it. The action doesn’t affect the warning and fault alarm.

5.10 Operation in warning status

1) In case the Fault/Warning

icon

is flashing and the buzzer is beeping once every second, it shows that the UPS system have some troubles, please check the troubleshooting table in chapter

4 to find out what happen to the UPS.

2) If the warning happens, the UPS will continue work in the original mode, the operation will not be interrupted. If the error is corrected, the warning alarm will stop.

29

5.11 Operation in fault mode

1) In case the Fault/Warning

icon

is lightened constantly and the buzzer beep continuously, it shows that there must a fatal error happen to the UPS and it is operating in abnormal mode.

2) If fault happens, please notes and record what the display shows, the display information is very important for the trouble shooting.

Please refer to the troubleshooting table in chapter 4 for detail.

3) Please check your loads, wiring, ventilation, mains, battery and so on after the fault happens. Don’t try to turn on the UPS again before find out the reason. If the trouble can’t be shooting, please contact the distributor or service people.

4) In the emergency case, please cut off the connection from mains / external battery / output immediately to avoid more risk or danger.

5.12 Output socket

There are two Output sockets. Output socket 1 always on, but

Output socket 2 has automatic on /off function. This function can be set by via software. Send command PET enable this function, Send command PDT disable this function, this function default disable, if the automatic on/off function is enabled, the Output socket 2 will cut off output when come in battery mode for 10 Seconds, and will recover output after one minute when come back to line mode or bypass mode. This function is aim to protect crucial load on Output socket 1. So if the crucial load please connects to Output socket 1.

5.13 Setting by LCD module

The output voltage, output frequency, bypass state, and ECO mode could be set directly through LCD module. The output voltage could be set to 100Vac, 110Vac, 115Vac and 120Vac. The output frequency could be set to 50Hz and 60Hz. The operating mode of

UPS could be set between the Line mode and ECO mode .The bypass state could be set to enable and disable. But all the settings could only be done when the UPS is in bypass or no output mode.

30

In bypass or no output mode, pressing the “Select” button on the

LCD panel for more than one second, “100Vac” will flicker on the screen. And if pressing the “Select” button continuously again, the flickering character string would display “110Vac”, next to“115Vac”,

“120Vac”, “50Hz”, “60Hz”, “BPE”(means bypass enable),

“BPd”(means bypass disable), “ECO”, “UPS” in turn. And if pressing the “Enter” button for more than one second at this time, the output voltage or frequency or bypass state or mode state setting would be modified to the selected value. And if no any pressing on the“Select” or “Enter” button lasting for more than 30 seconds, the setting mode exit automatically.

The only one voltage value could be selected in “100Vac”, “110Vac”,

“115Vac”, “120Vac” at any time. The only one frequency value could be selected in“50Hz”, “60Hz” at any time. And the output voltage and frequency would be changed to the corresponding value after the right values are selected on the LCD panel and the UPS is turn on by pressing the “ON” Button. The UPS would turn to bypass mode after “BPE” is selected, and turn to no output mode after“BPd” is selected. The mode change would be active only after the UPS is turned on.

Here is an example for changing the output voltage from 110Vac to

120Vac through the LCD panel.

Step 1: The figure“100” would flickering after pressing the “Select” button.

31

Step 2: The flickering figure would change to “120” after pressing the

“Select” button three times again.

Step 3: Pressing the “Enter” button the new setting output voltage has been confirmed, turn on the UPS and the output is change to

120V.
