This section explains how to obtain information concerning active alarms in
addition to a history of each alarm on the system.
When an alarm becomes active on a sensor or analyzer, a number from 1 to 8
will become visible on the bottom of the screen (see
14) and if the FLASH BACKLIGHT option has been enabled, the entire
display will flash. The alarms may suggest an over- or under-range condition,
or a Sensor Warning.
"N" will appear on the bottom of the screen for an AquaTrend or network
alarm. AquaTrend or network alarms may appear when there has been a loss
of power or network communication.
If an alarm annunciator shows up at the bottom of the screen, follow these
steps to review the alarm:
1. Press the MENU key to begin at the Main Menu.
2. Press the up arrow key to move the pointer to the ALARM LOG option
and press ENTER.
3. Select the alarm group you want to review and press ENTER.
4. Select any alarm and press ENTER to review information about
that alarm.
Note: The AquaTrend Interface can display up to 14 alarms for each alarm group.
5. Details of the selected alarm including the date and time the alarm
occurred will appear on the screen.
