TOSHIBA 6.0 Operating the UPS Operating the UPS 6.1.1 AC Input Mode (normal operation) The following illustration shows circuit power flow when the UPS is operating normally in the AC input mode. The UPS unit's rectifier, including a boost chopper circuit, converts AC input power to DC power.
Power flow in battery backup mode for the 75 and 100 kVA models Battery Backup Time and Discharge Process The UPS system, when used in conjunction with a Toshiba designed Battery System, is designed to provide several minutes of back-up time for the 75, 100 kVA models (Refer to the Battery System Manual for back-up times).
TOSHIBA The following illustration graphically shows the battery discharge process at full load conditions. Battery Low Voltage Tolerances Excessive discharge will cause the UPS system's battery voltage to drop bellow tolerable levels. The chart shown below lists the voltage level at which each UPS unit's low-voltage alarm will sound, and also at what level the low-voltage condition will cause the unit to automatically shut down.
TOSHIBA The recharge process usually consists of three periods. During the first period, the charging current is maintained at approximately 38.0 amperes. This current is the maximum value that can be used to charge the batteries (for minimal recharge time) while assuring safety and long battery life.
TOSHIBA EPO (Emergency Power Off) Function These units are equipped with terminals for receiving an emergency power-off (EPO) "closed contact" switch command from two locations: (1) a remote location (see Section 4.3 Terminal Block Details) and (2) from a front panel mounted EPO switch (see Section 6.5 "Front Panel Layout).
TOSHIBA Light Emitting Diode (LED) Functions The following list describes the conditions necessary for each LED lamp to be "on". This green LED lamp is "on" when the UPS is not in an input over-voltage condition, input under-voltage condition, or power failure state. If there is an input power failure, this lamp is "off".
TOSHIBA Liquid Crystal Display (LCD) Functions The liquid crystal display (LCD) screen is a 4-line by 20-character wide display. The LCD display contains information about the operation of the UPS. It should be used in conjunction with the LED display (see Section 6.8) and the audible alarms (see Section 6.7) for total system monitoring.
TOSHIBA 6.9.4 Line-4 System Messages Line-4 messages reflect the UPS operating conditions. Warning messages will be displayed when an abnormal operating condition occurs. The following chart shows the allowable Line-4 messages. Line-4 Messages Displayed Message Meaning Displayed when input Phase rotation is not wired for PHEI clockwise rotation.
TOSHIBA 6.10 Initial Battery Charge The UPS System's battery must be charged before it is used for the first time or when the unit has not been used (AC power source removed) for more than 10 days. Use the following procedure to recharge the UPS System's battery: 1) Switch on power at the UPS input distribution panel.
TOSHIBA 6.11 Start-up Procedure The UPS batteries must be charged before the UPS is used for the first time or if the unit has not been used (ac power source removed) for more than 10 days (Refer to Section 6.10). If the batteries are charged then use the following start-up procedure: 1) Verify that all power switches are off, and that the "RUN / STOP Switch on the UPS is in...
TOSHIBA 6.12 Shutdown Procedure When turning off the UPS, the following shutdown procedure should be used: 1) Move the unit's STOP/RUN key switch, located on the front panel, to STOP. Operation of the UPS unit's inverter stops. Output power is now provided to the load through the unit's bypass circuit.
