on-screen animation indicating the general state of water flow through the analyzer. In on-line
TOC, conductivity, or manual TOC modes, the animation area also serves as an alarm
condition indicator. If an alarm occurs in an on-line mode, the following sequence of events

• When a TOC or conductivity alarm condition occurs, the home screen animation area
• The animation area continues to flash red until a user acknowledges the alarm. See
