5. Maintenance and inspection

When maintaining the connected equipment, turn OFF the power switch and disconnect the AC input plug.

● Even if you disconnect the AC input plug while the UPS is operating, the power output of this unit does not stop and power is supplied from the outlet during a power failure.

Do not disassemble, repair, or modify the unit.

● Doing so may cause an electric shock or a fire.

If fluid leaks from the unit, do not touch the fluid.

● Doing so may cause blindness or burns.

●

If the fluid contacts your eyes or skin, wash it out with lots of clean water and consult your doctor.

Do not throw the unit into fire.

● The lead battery in the unit may explode, or leak dilute sulfuric acid.

5- 1 Checking the battery

The sealed lead battery used in the unit has a limited life. (The life varies depending on your storage/use environment and backup frequency.) The nearer the end of the life is, the more rapidly deterioration proceeds.

1. Life of battery (estimated replacement timing)

2. Method to check the battery

There are 3 methods for checking the battery.

• Perform a self-diagnostic test. (See page 31.)

• Use the auto battery test function. (See page 31.)

• Measure the backup time. (See page 46.)

By measuring the backup time, the battery life can be determined more accurately.

See also

Measure the backup time according to "7-1 Measuring method of the backup time." ➛ Page 46

If the measured value is equal to the "initial value of the backup time" or less than half the value obtained from the graph of "Estimated backup time" on page 46, replace the battery.

• When you compare the "initial value of the backup time" you measured and the current backup time, make the capacity of devices connected to the UPS same as when you measured the initial value to make judgment accurately.

3. Guideline on the frequency of checking the battery (measuring the backup time)

* The battery deteriorates even if it is stored. The higher the temperature is, the shorter the life

becomes.

6. Using the Contact Signal

(only for BX50FW, BX75SW)

You can develop your unique system based on the following specifications to automate the process at the power failure.

Your can perform power-failure or closing procedure of the system by detecting the Backup Signal and the Battery Low Signal, or receive failure notification by detecting the Trouble Signal.

You can stop the UPS by inputting the UPS Stop Signal from the system, and remote control start and stop of the UPS by using the Remote ON/OFF Signal.

Also, this function is valid only when “connection communication” is selected for the “switching switch”. (See item 2 on page 34.)

1. Signal output

The UPS has 5 kinds of output signals. The output circuit consists of an open collector circuit using a photo coupler (a kind of electronic switch).

● Backup Signal output: BU

Backup Signal reverse output: NBU

BU stays ON (NBU OFF) during a power failure.

NBU is output only when the”gcommunication connector 9th-pin output signal switching setting” (setting switch 8 ) is set to ON.

● Battery Low Signal output: BL

Goes ON when the battery becomes weak during the Battery Mode.

● Trouble Signal output: TR

Goes ON when an internal failure of the UPS occurs.

● Battery Replacement Signal output (WB)

Goes ON when the battery needs to be replaced due to deterioration.

WB is output only when the “communication connector 9th-pin output signal switching setting” (setting switch 8 ) is set to OFF.

2. Input of the UPS Stop Signal (BS)

Stops the output of the UPS after the time period specified by the “power output stop delay time setting” (setting switches 5 and 6 ) has elapsed.

(1)

When the "UPS Stop Signal setting" (setting switch 7 ) is set to OFF:

You can stop the output of the UPS by inputting the voltage signal (HIGH) that lasts at least 10 seconds from the outside.

(2) When the "UPS Stop Signal setting" (setting switch 7 ) is set to ON:

You can stop power output by inputting the voltage signal (HIGH) that lasts at least 0.01 second (10 ms) from the outside that is accepted only during backup.

9. Precautions and notes on the use of the Contact Signal

Notes

● When connecting a device that generates counter electromotive force to the signal output circuit such as a relay, connect diodes to prevent counter electromotive force at the both end of the relay.

Explanation

● When power is restored after the unit stopped automatically during a power failure, the unit automatically restarts and supplies power. If you do not want to start the connected devices, turn OFF their switches or set the auto restart setting (setting switch 2) to ON. (See page 32.)

7. Measuring the backup time (checking the discharge time of the battery)

7. Measuring the backup time

(Checking the discharge time of the battery)

7-1 Measuring method of the backup time

(1) Connect the AC Input Plug of the UPS to a wall outlet (commercial power) and charge it for approximately

12 hours. If you operate the UPS for 12 hours or more, it is charged. If a power failure occurred during this period, charge it again.

(2) Turn ON all devices connected to the power output to be “backed up during a power failure”.

(Including devices connected to the AC outlet of your computer.) Operate them in a way in which it is allowable that power supply to the connected devices stops.

● For Windows Server 2003/XP/Me/2000/Windows NT/Linux:

To be performed in case of hard drive stops.

● For Windows 98/95:

Choose Shut Down of Windows and follow the procedure below to shut down your OS.

Choose "Restart in MS-DOS mode" to exit from OS and display the MS-DOS mode screen.

(3) Disconnect the AC Input Plug of the UPS and measure the backup time.

Measure the time until the unit automatically stops and all displays disappear with the plug disconnected.

* The backup time you measure for the first time after purchase is the "initial value of the backup time."

7-2 Estimated backup time

The backup time varies depending on the capacity of connected devices. After calculating the total capacity of connected devices, refer to the graph of the backup time to obtain an estimation of the initial value of the backup time. (This is also applied to checking the battery.) (1) Unify the total capacity (power consumption) of connected devices to W (Watt).

For the indication of connected devices, check your computer and the rear of the display. There are 3 types of indication: VA (Volt·Ampare) indication, A (Ampare) indication, and W indication.

Example 1) 100 VAC, 50/60Hz,

145 W

Example 2) 100 VAC, 50/60Hz,

1.8 A

Example 3) 100 VAC, 50/60Hz, 150 VA

For devices that use the VA or A indication, convert the capacity into W. Multiply the value indicated on devices by the value in the right table for conversion.

(When the power factor is unknown, enter “1”. The power factor usually ranges between 0.6 and 1.)

(2) Add the values converted into W to obtain the total capacity of the connected devices.

Indication Value

VA × power factor = W

A × power factor × 100 = W

Page 49

7. Measuring the backup time (checking the discharge time of the battery)

(3) Calculate the initial value of the backup time for the total capacity of the connected devices from the graph

below.

● Graph of backup time (initial value for product that has not been used)

● The smaller the capacity of connected devices becomes, the longer the backup time becomes.

8. Troubleshooting

UPS does not operate. The LED display does not light up, even though the AC input plug is connected to a wall outlet (commercial power) and the power switch is ON.

Backup is not possible. The computer stops when a power failure occurs.

Backup is performed too frequently. Frequent switching is performed although a power failure does not occur. You hear the sound of switching.

The display is abnormal.

● The display is unstable.

● White lines occur.

● Noise increases.

The battery replacement lamp blinks and the beeper sounds at 2-second intervals.

The status indicator shows “

”, and the beeper sounds

at 0.5-second intervals.

The status indicator blinks “ ”, and the beeper sounds continuously.

The output voltage is only approximately 80 V when measuring it with a tester.

8. Troubleshooting

Perform the checks shown below if the unit is operating abnormally. If the unit continues to operate abnormally, please contact our Electronic Systems & Equipments customer support center at _____.

Problem

1. Check that the AC Input Plug is connected to the commercial power securely.

2. The AC Input Overcurrent Protection worked and opened. (If the black button is popped up, it is suspected that there are too many connected devices or there is a short in connected devices.) Disconnect all of the connected devices, push in the AC Input Overcurrent Protection Black Button, and turn on the Power Switch of the UPS again. If the status indicator does not display normally, there is a problem with the UPS. (See "Interpreting a beep and display" on page 29.)

3. Isn't the voltage of the wall outlet (commercial power) too low? Stop devices that consume a lot of power such as an air conditioner. Check the UPS, for example, by connect it to a wall outlet (commercial power) in another room or house. (It does not operate when the voltage is less than 90V.)

Isn't charging insufficient? Perform the test after charging the battery for at least 12 hours. You can charge the battery by connecting the AC input plug of the UPS to a wall outlet (commercial power).)

1. The input power supply may be at fault. Connect the UPS to a wall outlet (commercial power) in another room or, if possible, another house and check it. Or, stop large devices such as a cooler.

2. Isn't a page printer connected? Because large current flows instantaneously in printers, normal backup is not possible.

1. The UPS generates some noise when performing backup. For displays susceptible to noise, distortion or white lines may occur, but the UPS is not at fault.

2. Grounding the UPS, computer, and display may improve this problem.

3. Noise during backup may become larger depending on connected devices, you can continue to use the UPS because this occurs due to rectangular wave output.

The battery is judged to be dead in the auto battery test or the self-diagnostic test. Battery Mode cannot be performed and therefore replace the battery pack.

There are too many connected devices. There are too many connected devices. Reduce the number of connected devices until “

” is displayed on the status indicator.

The UPS stopped because too many devices were connected for 3 minutes or more, or because 120% was exceeded. Turn OFF all power to the unit and connected devices, and reduce the number of connected devices. Then, turn the power to the unit and connected devices back ON and check whether "

" is displayed on the status indicator.

The UPS outputs a special rectangular wave during the Batter Mode. Due to its characteristics, simple testers indicates approximately 80 V. The UPS is not at fault. To make correct measurement, you need a voltmeter that can measure "true rms value."

About the included UPS monitoring software

Using the included UPS monitoring software allows you to automatically save data files and shut down your computer when a power failure occurs. However, make settings so that the time from the occurrence of the power failure until computer shutdown is less than the maximum backup time. For more details, refer to the instruction manual and online help for the UPS monitoring software.

Using the included UPS monitoring software also enables you to change the unit’s operation mode settings, use additional functions, perform scheduling operations, etc.

Explanation

Starting operation during a scheduled stop with UPS monitoring software

● If the unit starts operation during a scheduled stop period, turn the power switch OFF once, and then turn it back ON.

You can start the unit manually. In this case, the next scheduled ON operation is cancelled.

Auto restart after OS shutdown by UPS monitoring software

● In the event of a power failure, some PC models (see *1 below) automatically restart immediately after the completion of the OS shutdown processing by the UPS monitoring software. In this case, the unit stops during restart or after startup, possibly damaging files and/or the hard disk. This problem can be avoided by disabling POWER MANAGEMENT in the BIOS settings. *1) PC models: This problem has been reported with MICRON Millenia Mme.

● When the PC does not start up automatically, select the “System startup at power restoration” setting (example: “Restore On AC/Power Loss) in the BIOS settings of your PC, and change to a “System startup after power restoration” setting (example: “Power On). Individual BIOS setting methods and/or displays may differ depending on the PC. For more information, refer to your PC instruction manual or the technical support center for your PC.

● When considering a system with automatic startup at power restoration, choose a PC that satisfies the condition shown below. For more information on PC operation when input power is supplied, consult your PC instruction manual or contact the PC technical support center. <Condition> Without pressing the power switch, the PC starts up when input power is supplied.

● After shutdown processing in the event of a power failure, the unit restarts automatically and supplies power once power is restored.

If you do not want the devices connected to the UPS to start up, turn OFF their switches.

● The automatic restart setting can be disabled in the included UPS monitoring software.

D. Circuit block diagram

This UPS outputs power input from commercial power as it is and charges the battery at the same time. If a power failure or voltage variation occurs, the UPS automatically switches to operation using the battery and continues power output. At this time, the beeper sounds intermittently. When the power is recovered, normal operation using commercial power is automatically recovered. (The beeper stops.) You do not have to perform any operation.
