The sensor unit performs the measuring tasks at preset intervals, 
sends the data and then returns to idle to save energy. 

In addition to the time-controlled measurements, the sensor unit 
can be configured to perform vibration measurements based on 
events. In this mode, the sensor unit continuously monitors the 
respective measuring channel and automatically starts a measure-
ment when the vibration exceeds a preset level (0-p). The power 
consumption for continuous monitoring is lower than that for 
actual measurements. For technical reasons, only one event-
controlled measurement can be performed within the interval 
between two time-controlled measurements. The triggering con-
ditions for each measuring task are set in OMNITREND.

Each measuring sequence takes about 3 seconds, while the send-
ing of the data might take up to 30 seconds. The duration of the 
idle phase is set in OMNITREND for each sensor unit to a time 
between 30 minutes and 1 week.
To explain the function of a sensor unit in a radio cell, a number 
of typical scenarios are described below in the form of questions 
and answers.

•   Each sensor unit is assigned a unique code, known as the MAC 

address. This code is pre-programmed in the radio module and 
cannot be altered. A sensor unit is assigned to a bridge in the 
OMNITREND software, using its MAC address.
