OPERATION

Control / Display Panel

The control panel includes tactile pads (dome buttons) and a menu-driven LCD (liquid crystal display). The display provides full metering, present status, and alarms, if any. See figure on right.

Control Buttons

ON Button - This button turns on the UPS inverter. It supplies power to the output if the Output Circuit Breaker is closed. The ON button also restarts the UPS after a manual shut-off.

OFF Button - Press this button twice to cause an orderly shutdown of the unit. The unit turns OFF all power to loads, including bypass, and disables Auto-Restart until the ON button is pressed. However, the display remains active and the batteries still recharge. Pressing the button only once causes a return to normal operation in a few seconds. This control feature helps avoid accidental shutdowns.

Note: If you press the OFF button a third time, a display message prompts you to press it a fourth time which opens the Output Circuit Breaker at the rear.

Alarm Silence Button - This button silences alarms. The alarm sounds if a new alarm occurs.

LCD Display

The menu-driven LCD display has four (4) lines of text (16 characters per line) on a screen to indicate status, alarms, metered conditions, and user selections. The display controls include four (4) buttons to view or select UPS conditions:

Left Arrow - Returns to previous screen or value Right Arrow - Advances to next screen or value

Enter - Selects a menu, display, or value and enters selected values into the control program

Escape - Cancels selections. It returns values to original settings and the display to the main menu.

The LCD panel displays messages and operating parameters. It usually displays a Normal Operation screen (see figure on right) which includes date, time, and a prompt on the help line to select the Main Menu. Alarms or faults displace the Normal Operation screen.

The user screens are organized in a multi-level menu system (see page 13). Select a choice with the keys below the screen. The Enter key moves the cursor to the next lower menu level. The Escape key returns the cursor to the previous menu. Use the Left and Right keys to scroll through available options and to select user- programmable values. The cursor indicates which value is active. Press Enter to record the value after each selection.

Initial Start-Up

At initial start-up, the LCD display prompts the user to

review or change the configuration. The initial configuration menu allows the following selections: Review Configuration, Change Settings, UPS Meters, and Accept Settings.

After reviewing or changing the output configuration, then accepting it, start-up self tests begin. The selected configuration is stored in control memory even with no power to the UPS.

Self tests begin immediately if power is applied after initial start-up. Configuration review is optional.

The unit will not repeat most self tests when turned OFF then ON because power is not removed from control logic. Upon turning it ON, the unit tests the inverter. To start unit, close the Output Circuit Breaker.
