Figure 47 Alarm Limits Shown on Graph Screen
When an alarm is activated, an alarm note is displayed on the display,
and the lights of the display will blink. If the data logger module is
installed, the alarm note includes the time and date of the alarm.

Figure 48 Display Alarm Active
Multiple alarms can be active at the same time; the alarm that was
triggered first will be shown on the display. The next active alarm is
revealed when the currently shown alarm is acknowledged by pressing
the OK button.
Activated alarms are only shown on the screen; there are no alarm
messages output to the serial line. After an alarm has been
acknowledged, you must refer to the data graphs to see when the
measured quantities have exceeded the limits. You may use the optional
relay outputs as alarm outputs by configuring them separately; see
section Setting Relay Outputs on page 129.
Configuring a Display Alarm
1. Enter the Main Menu by pressing an arrow key on the keypad.
2. Use the arrow keys to select Display, followed by Alarms, to open
the Display Alarms menu. The Display Alarms menu shows the
currently enabled and disabled alarms.
