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 the Relay Outputs on page 134.
