PRODUCT DESCRIPTION

Theory of Operation
An uninterruptible power supply, or system, is a device that is installed between commercial power and load equipment. The UPS provides steady AC power
to the load during commercial power uctuations and interruptions.
During normal operation the UPS uses commercial AC power. It also takes in all of the high voltage spikes and transients caused by switching and faults, and all of the common mode and normal mode noise which is associated with
commercial AC power. The UPS converts this input to at DC power. From
this DC power, the UPS generates its own extremely high quality AC output. The result of this process is maximum power conditioning.
If the AC power supplied to the UPS drops below a specied voltage level, the
unit’s batteries automatically begin supplying the power instead of receiving it. This insures that the load connected to the UPS continues to receive power
without interruption. When commercial AC input power becomes available
again, operation returns to normal. The unit’s batteries begin to recharge so they will be ready for the next power interruption.
Application and Use
Toshiba’s 1800 Series of on-line Uninterruptible Power Systems (UPS) provides continuous computer-grade AC power in a compact, high performance,
energy efcient unit. The UPS assures safe and reliable operation of critical ofce equipment, minicomputers, and local area networks. All units feature
an audible alarm which sounds if the battery voltage drops below standard
during use. This is an additional aid to help in retaining the valuable ofce
data banks. All units allow for computer interfacing for remote control and monitoring, and an external battery pack option for extended backup operation.
(See Specications)
Power Backup
During an electrical power failure the batteries of the UPS unit supply DC power to the inverter that supports the load equipment automatically, without interruption. For example, when used to support a computer, a UPS backup assures additional time to complete your activity and save data after a power failure occurs.
11
Power Conditioning
While commercial power is present, the UPS supplies conditioned power to the
load while maintaining the batteries in a charged condition. The UPS protects the connected load against the normal everyday problems associated with heavy use of raw commercial power, including power sags, signal interference, and spikes. This protection keeps power-line problems from reaching your load where it can cause equipment to operate erratically, or damage software or hardware.

STARTING THE UPS SYSTEM

Ensure the input breaker is switched on (Figure, page 15). When the “AC Input” LED is lit switch the RUN/STOP switch to the RUN position (RUN = I, STOP = 0).
When the RUN/STOP switch is in the RUN position both the “AC Input” and
the “On Line” LEDs should be lit. It is advisable to allow time for the batteries to fully charge before any load is connected (see “Battery Recharge Time”, page 24).

STOPPING THE UPS

There are two ways to turn off the UPS: switching from online to bypass mode, or completely shutting down.
OPTION 1
The rst option is to place the UPS into bypass mode. Bypass mode means
that if there is AC power available, the UPS will route power directly from the input source to the connected loads without any conditioning. The UPS inverter is off during this state, but the attached loads do not lose power during the transition. To place the UPS into bypass mode, switch the RUN/STOP switch to the STOP position. This mode is most often used manually during maintenance operation or automatically upon the occurrence of an internal UPS fault. (For more information concerning bypass mode see Appendix D:
Bypass Undervoltage / Overvoltage).
OPTION 2
The other option is to turn the UPS off completely. This means that in addition to the UPS’s inverter shutting down, all power will be stopped to any equipment attached to the UPS. To shut the UPS down completely, switch the RUN/STOP switch to the STOP position. Then switch the input breaker off (Figure, page 15). Once the input breaker has been switched off, all the LEDs should turn off.
If the RUN/STOP switch is in the RUN position when the input breaker is switched off, the unit will switch to battery backup mode. The unit will continue to run for as long as the available battery reserves can support the connected loads.

All other display conditions constitute either a warning or a fault condition. These conditions are explained in the section titled
“Troubleshooting” (page 28) in the charts on Warnings and Faults.
Note 1: The level meter, which consists of the LEDs labeled 20% through 150%, will light according to the current amount of
load connected. As the load exceeds one level, the next level will begin to blink, increasing the blink rate as the load increases
until that full percentage is reached. For example, if the unit is loaded to 40% of maximum output power the 20% and 40%
LEDs will be lit. If another small load is added increasing the load to 45% the 60% LED will begin to blink. If a little bit more
load is added so that the total load becomes 50% the 60% LED will blink faster. This will continue until enough load is added to
equal 60% of the maximum output power at which time the 60% LED will stop blinking and light continuously.
Note 2: The level meter described in Note 1 above also displays the remaining battery time when the unit is in backup mode.
If the batteries are fully charged when the unit switches to backup mode the 20% through 100% LEDs will light. As the batter-
ies begin to discharge, the LEDs starting from the top will blink rapidly then slowly and will then turn off as the battery time runs
down. For example if the unit has been running on battery power and there is 90% battery capacity remaining the 20% through
80% LEDs will be lit and the 100% LED will be blinking.

BATTERY BACKUP TIME

The exact amount of backup time provided will vary depending on the UPS model being used, number of batteries, condition of the batteries and other factors. However, the chart below gives the times that can be expected from the standard units with batteries in good condition. For longer runtime options contact your Toshiba sales representative or the Toshiba marketing department
at 877-867-8773 or by e-mail at toshibaups@tic.toshiba.com.

BATTERY CHECK FUNCTION

During startup the UPS will perform an automatic ‘Battery Check’ to detect whether a problem exists in the battery circuit. If the batteries pass the test, the unit will start normal operation. If a problem is detected during the test the
“Warning/Fault” LED will activate. Other LED’s may also activate. If this occurs
please refer to the “Troubleshooting” section on page 28 for a description of the problem and possible solutions. It is important to note that when the UPS has detected bad batteries, the battery backup mode is disabled. The unit will continue to operate and provide clean power; however, since there is no battery power available, the unit cannot provide backup power if input power is lost.

THE FUNCTION CONTROL BUTTON

The function control button is located on the display panel (see “Display Panel Layout”, page 19). This button is used to perform different UPS operations,
including initiating a self test, and silencing the alarm. A brief description of each function follows:
1) Self-Test. In order to perform a self-test the UPS must be operating in the
normal mode (see “UPS Display Status and Operating Condition”, page 22). To initiate the self-test simply press and hold the Function Control button until the audible alarm sounds. The self-test also performs the same battery check described above.
2) Alarm Silence. The alarm silence feature is used to stop the audible alarm
from sounding. Any time the audible alarm is sounding, quickly pressing and releasing (in less than 1 sec.) the Function Control button will silence the alarm.

more information contact Toshiba’s UPS Marketing Department at (800) 231­1412 or by e-mail at toshibaups@tic.toshiba.com.

TROUBLESHOOTING

Warnings and Faults are those abnormal conditions that can occur and could
cause the unit to stop normal operation. These conditions are detected by
the protective circuitry in the unit. The UPS “Warning/Fault” lamp will light red
when a warning or fault occurs.
“Troubleshooting” involves monitoring the LED’s on the front panel and then interpreting the readout by using the warning and fault mode display charts that follow. Only the state of the LED’s listed in the chart should be considered. Other LED’s might be active; nevertheless, only those listed under the column “LED state” should be considered when diagnosing a warning, or fault.

WARNING/FAULT MODES

All warnings will cause the red “Warning/Fault” LED to ash. All faults will cause the red “Warning/Fault” LED to light continuously.
Some warnings and most faults will cause the UPS to transfer to bypass mode. In many cases, after the condition that caused the fault is corrected the unit will automatically transfer back to normal mode. For those cases where the unit does not transfer back automatically contact your Toshiba UPS service
representative at 1-877-867-8773 (outside the U.S. call 713-466-0277).

STORAGE OF UPS EQUIPMENT

GENERAL GUIDELINES

If the UPS equipment is to be stored; the following guidelines should be used.
Avoid:
1) Storage in sites subject to extreme changes in temperature or high humidity.
2) Storage in sites subject to exposure of high levels of dust or metal particles.
3) Storage on inclined oor surfaces or in sites subject to excessive
vibration.
Before Storing:
1) Allow UPS to be operated for 4 hours to ensure that the batteries
are fully charged.
2) Stop the unit (see “Stopping the UPS” on page 21).
3) Place the unit’s Input Breaker switch in the “off” position (see “Layout”, page 15).
Storing:
1) Store within a temperature range of -4° to 104°F (-20° to 40° C).
If the UPS is stored at a temperature outside of the allowable operating range, allow time for the unit to reach equilibrium with the ambient temperature before starting the UPS.
2) For best results, store the UPS in the original shipping container and place on a wood or metal pallet.
3) The optimum storage temperature is 70°F (21° C). Higher ambient
temperatures cause UPS batteries to need recharging more frequently.
35
Recharging requirements during storage:
Recharging the batteries requires that the UPS has AC input power available. The UPS can be in either the online or bypass mode. (See
“Starting the UPS System”, page 20, and “Battery Recharge Time”, page 24).
1) If stored in an ambient temperature less than 68°F (20°C), recharge
the batteries every 9 months.
2) If stored in an ambient temperature of 68° to 86°F (20° to 30°C), recharge the batteries every 6 months.
3) If stored in an ambient temperature of 86° to 104°F (30° to 40°C), recharge the batteries every 3 months.

DISPOSAL

Please contact your local environmental agency for details on disposal of electrical components and packaging in your particular area. It is illegal to dump lead-acid batteries in landlls or dispose of improperly. Please help our Earth by contacting the environmental protection agencies in your
area, the battery manufacturer, or call Toshiba toll-free at 877-867-8773 for
more information about recycling.

PREVENTIVE AND SCHEDULED
MAINTENANCE/PARTS REPLACEMENT

PREVENTIVE MAINTENANCE

Toshiba’s 1800 Series of UPS’ have been designed to provide years of trouble­free operation requiring a minimum of preventive maintenance.
The best preventive measure is to keep the area around the unit, particularly the air inlet vents, clean and free of moisture and dust accumulations. If the atmosphere of the installation site is very dusty, use a vacuum cleaner to periodically remove dust accumulations from the exterior of the unit, especially around ventilation openings. Schedule authorized Toshiba service centers to perform internal parts inspections annually, or call a Toshiba UPS service
representative at 1-877-867-8773 (outside the U.S. call 713-466-0277).
Note: Disconnect AC source before servicing
CAUTION
Proper maintenance of the battery system of this unit is essential to the safety and reliability of the UPS system.

PARTS REPLACEMENT

The following list shows intervals for periodic maintenance and replacement of certain UPS parts.
1) Batteries: Replacement should be done once every 3 to 5 years at a
minimum.
2) Cooling Fans: Replace once every 3 to 4 years. (Fan replacement must
be done by Toshiba authorized service personnel).
3) Battery Fuses: Replace the battery fuses every 7 years.

APPENDIX B: SYSTEM OVERLOAD

The 1800 Series UPS is capable of supporting short duration overloads.
Online Mode:
When operating in the On Line mode if the output load goes above the rated
load, the unit may start beeping indicating output overload. Output overload­ing of 125% of the rated output current can be supported for 1 minute, and
150% for 30 seconds. If the overload continues and does not drop to the
nominal rated load, the unit will eventually transfer to bypass mode.
Bypass Mode: If the output load is reduced below the output power rating, the unit will return to normal. If the unit transfers to bypass due to output overload twice in 10 minutes, the “return to normal” function is disabled and will never return to online mode until the alarm is reset by cycling (turning off then on) the input cir­cuit breaker. If the unit is in bypass mode and the output load is not reduced, the unit will eventually go to shutdown.
40

APPENDIX C: PARALLEL OPERATION

The 1800 Series UPS offers a standard feature that allows the unit to operate with very low input voltage without de-rating the output power. If the input voltage drops below a certain point the unit will switch to parallel mode. Parallel mode means that the unit is using the available input voltage and supplementing with battery power. Because battery power is being used, the time the unit can operate in parallel mode is limited. However, the time will be longer than that available when the unit is operating on battery power alone.
The point when the UPS will enter parallel mode will vary depending on the output load. The following graph illustrates the UPS’ transition from battery
to line power as the line voltage increases from 40% to 100% of normal.
Transition curves are shown for 75% and 100% output load.

Input Voltage (%)
As shown in the graph, the lower the output load, the lower the input voltage can go before parallel mode is activated. However, the minimum input voltage
will always remain at 60% (72 VAC for a 120 VAC system).
41
APPENDIX D: BYPASS UNDERVOLTAGE /
OVERVOLTAGE
When the 1800 Series UPS is in bypass mode the undervoltage and overvoltage
limits are restricted to +/-10% of the rated input voltage. If the input voltage is outside of this voltage window the UPS output will be turned off. There is a 5% hysteresis associated with both the upper and lower limits. This means that once output has been turned off the input voltage will have to be within ±5% of the rated input voltage before the startup sequence will re-initialize.
When the UPS is started, if the RUN/STOP switch is in the STOP (bypass)
position the unit will start in the on-line mode for 1 second before switching to bypass mode. If the input voltage is out of range the UPS will turn off the output after 1 second rather than switching to bypass.
