Acceleration sensor
In case of acceleration sensor, the unique selection available is related to the sampling rate.
Indeed, there is a band-pass trigger filter on the data between 0.5 and 15 Hz. This means that the
trigger condition is reached only if the two following conditions are fulfilled:
the trigger level is exceeded;
•
the peak is associated to a frequency in the range 0.5 – 15 Hz.
•

Alarm

The alarm service checks if the vibration exceeds the defined alarm threshold levels. In this case,
the notification service of the MR3000 sends an e-mail or SMS to the people listed in contacts
where Alarm 1 or Alarm 2 have been checked (see chapter 4.4.4).
Indicator time (seconds) is the period between the first exceeding of the alarm threshold and the
end of the alarm condition. For event related alarms this setting is not relevant. For the difference
between Alarm based and event based messages see chapter 4.4.4.
It is possible to define two levels of alarms: alarms 1 and alarm 2. They can be configured
completely independently.
In the field "Based on", the alarm can be activated on the trigger or on the background recording. In
the following, let us analyze the two situations separately.
The alarm functionality explained in this section is related to the case of velocity sensor (internal or
external).

Values exceeding the trigger threshold do not necessarily lead to an event
creation.
