Chapter 3 Understanding UPS Operation

The UPS functions automatically to supply AC electrical power to the critical load. The UPS always operates in one of three modes:

쑺 In Normal mode, the critical load is supplied by the inverter, which derives its power

from rectified utility AC power. In this mode, the rectifier also provides charging current for the battery.

쑺 In Bypass mode, the critical load is directly supported by utility power.

쑺 In Battery mode, the battery cabinet provides DC power, which maintains inverter

operation. The battery supports the critical load.

The UPS continually monitors itself and the incoming utility power, and automatically switches between these modes as required, with no operator intervention. The sophisticated d etection and switching logic inside the UPS ensures that operating mode changes are automatic and transparent to the critical load. The UPS switches operating modes in response to these system events:

쑺 A command is an intervention that is externally initiated by an operator or by some site

action. A command causes the UPS to switch operating modes; it usually does not require any further action by you.

쑺 A notice is a minor system event that may or may not require your attention.

쑺 An alarm is a system event that requires immediate operator intervention.

System events, alarm horns, and indicator lights are described in Chapter 10, “Responding to System Events.”

3.1 Normal Mode

In Normal mode, utility AC power is supplied to the rectifier. The rectifier supplies DC power to the inverter, which then supplies the critical load with AC power. The rectifier also provides charging power to the battery. The battery charge condition is monitored by the UPS and reported by a status indicator on the Monitor Panel. The message “System Normal” appears in the status area of the LCD screen.

Figure 3-1 shows the path of electrical power through the UPS system when the UPS is operating in Normal mode.

If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode to support the critical load with no interruption. When utility power returns, the UPS returns to Normal mode.

If the UPS system becomes overloaded, the UPS switches to Bypass mode. The UPS automatically returns to Normal mode when the error condition is cleared and system operation is restored within specified limits.

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until the failure is corrected and the UPS is back in service.

You can transfer the UPS from Normal mode to Bypass mode manually. However, the UPS switches automatically to Bypass mode whenever the inverter can no longer supply the critical load. If the UPS transfers to Bypass mode from Normal mode due to any reason other than operator intervention, the UPS automatically attempts to transfer back to Normal mode (up to three times within a 10-minute period). The fourth transfer will lock the critical load on the bypass source and requires operator intervention to transfer.

Bypass mode is a normal operating mode, and not an alarm condition. However, if the UPS is unable to return to Normal mode following an automatic transfer to Bypass mode, an alarm condition is recorded.

Understanding UPS Operation

3.3 Battery Mode

The UPS transfers to Battery mode automatically if a utility power outage occurs, or if the utility power does not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the inverter converts to AC power. When the UPS switches to Battery mode, the alarm indications depend on the cause and condition of the battery charge. The length of time the system can operate in Battery mode depends on load configuration and the battery charge.

Figure 3-3 shows the path of electrical power through the UPS when operating in Battery mode.

CB1

When the discharging battery voltage reaches the lower limit of UPS operation capability, the critical load transfers to Bypass mode if it is available. If Bypass input is not available, a “Shutdown Imminent” warning occurs. The warning time before critical load loss occurs is approximately two minutes, depending on load configuration and the battery charge.

If incoming power returns to within specified parameters, the UPS automatically returns to Normal mode and alarm indications clear. However, the process of returning to Normal mode is not instantaneous. The rectifier gradually draws increasing power from the incoming utility until Normal mode is achieved.

3.4 Monitoring and Controlling UPS Operation

After you start the UPS, no operator intervention is necessary except for periodic checks of the UPS status. Manual operation is required only during routine maintenance or service. Use the Monitor Panel and the Control Panel to monitor and control the UPS. Figure 3-4 shows the location of these two panels on the front of the UPS.

Figure 3-4. Location of the Monitor Panel and the Control Panel

The Monitor Panel on the left front of the UPS continually indicates the present mode of UPS operation. This panel contains an LCD screen, backlit status indicators, and the LOAD OFF button. Use the LCD screen on the Monitor Panel to view performance meters or graphic representations of UPS operation. The Monitor Panel is described in detail in Chapter 5, “Using the Monitor Panel.” A quick reference label describing how to use the Monitor Panel is located inside the UPS above the Control Panel.

Open the right front door of the UPS to view the Control Panel containing various controls and switches. These control power to and from the UPS, and allow you to change the UPS mode manually. The Control Panel is discussed in “Using the Control Panel” on page 4-1.

Chapter 4 Starting and Stopping the UPS

This chapter describes how to use the Control Panel to start and stop the UPS.

NOTE

preliminary startup has been performed by authorized service personnel. The preliminary startup verifies all electrical interconnections to ensure the installation was successful and the UPS system operates properly.

Before starting the UPS, ensure all installation tasks are complete and a

4.1 Using the Control Panel

The Control Panel is inside the right-hand door of the UPS cabinet (see Figure 4-1). Although the Control Panel appears easy to use, you should read these instructions and thoroughly understand how the controls work before attempting to use them.

Incorrect use of the power controls on the Control Panel can cause a loss of power to the protected equipment.

Starting and Stopping the UPS

The following describes the switches on the Control Panel (see Figure 4-1):

쑺 The MODE switch is a two-position rotary switch that controls the manual transfer of the

UPS to and from Bypass mode. The MODE switch is used to:

- PlacethecriticalloadinBypassmodewhentheUPSisoperatinginNormalmodeand thebypasssourceiswithinacceptablelimits.Ifthetransferdoesnotoccurwithintwo seconds, an alarm sounds.

- Prevent transfer to Normal mode when the UPS is in Bypass mode.

- Shut down the power processing unit (inverter and rectifier) of the UPS.

쑺 The BATTERY switch is a two-position rotary switch that allows you to manually shunt

trip the battery breakers in remote cabinets.

쑺 The circuit breaker (CB1) switch controls the operation of the rectifier and inverter. If

CB1 is on (closed), the rectifier turns on when the START switch is activated and the propervoltageisattheinputterminals.

쑺 The PUSH TO RESET button is described in “Resetting the UPS System after Load Off” on

page 11-2.

쑺 The START switch activates the power controls on the Control Panel. The START switch

is center-biased (the key will rest only in the upright position). Its operation is similar to that of an automobile ignition switch. After setting the operator controls, you turn the START switch to the right momentarily to activate the c ontrols. When you release it, it returns to the upright position.

The following sections describe how to operate these controls to start, stop, or change the operating mode of the UPS.

4.1.1 To Place the UPS in Normal Mode

1. Close the Input Power Feeder breaker.

2. Verify that the Load Off PUSH TO RESET button is pressed in.

3. Turn the BATTERY switch to NORMAL.

4. Turn the MODE switch to NORMAL.

5. Move the CB1 switch to ON.

6. Turn the START switch to the right momentarily.

The rectifier turns on, then the inverter turns on. The UPS display and alarm alert you to close the battery breaker.

Starting and Stopping the UPS

When the inverter reaches full voltage, it turns on and supplies power to the critical load. It takes less than one minute for the UPS to achieve Normal mode.

IfabypasssourceisavailablewhenyouturntheSTARTswitchon,thecriticalload is immediately supplied by the bypass source in Bypass mode until the inverter turnsonandtheUPStransferstoNormalmode.Thestatusindicatorsonthe Monitor Panel indicate when the UPS is in Bypass mode or Normal mode as appropriate.

4.1.2 To Shut Down the UPS from Normal Mode

1. Turn the MODE switch to BYPASS.

The UPS switches to Bypass mode. If the bypass source is not available, the power processor remains on and an alarm sounds.

2. When the transfer is complete (the LCD screen reads “On Bypass”), move the CB1

switch to OFF.

The bypass source supplies the critical load and the power processor de-energizes. TheBypassmodeindicatorilluminatesontheMonitorPanel.

4.1.3 To Start the UPS in Bypass Mode

If the PPU of the UPS is not available and you need to energize the critical load right away, you can energize the critical load without the benefit of backup. To turn the UPS on in Bypass mode:

1. Turn the MODE switch to BYPASS. (The remaining switches can be in any position.)

2. Turn the START switch to the right momentarily.

Power to the critical load is supplied by the bypass source. No backup is available.

4.1.4 To Shut Down Power to the Critical Load While in Bypass Mode

To perform maintenance or service on the critical load, you must shut it down first:

1. Turn off all equipment that is being powered through the UPS.

2. Press the LOAD OFF button on the Monitor Panel.
