Make tap test of the accelerometers 

With the tab test can check the signal from each of the connected accelerometers and the speed 
sensor by using the Oscilloscope function of the VCM-3 Homepage. In addition, it can be checked 
whether the sensors are connected correctly to the VCM-3 input channels.  

 

 

NOTE! 

The intended use of the Oscilloscope function is during commissioning to check the 
input channel signal (raw sensor signal).  
The Oscilloscope function should only be used with the factory monitoring template for 
commissioning.  

     

By using this function with other templates than the commissioning (factory monitoring) 
template the Oscilloscope plot can freeze or the VCM-3 Homepage becomes 
unresponsive.  
When this condition occurs, the user usually has to call up another function on the  
VCM-3 homepage and then return to the Oscilloscope view.  

 

 

IMPORTANT NOTE! 

The measurement functionality of the VCM-3 is not affected by this behavior! All 
measurement functions of the VCM-3 hardware/firmware continue to run, alarm states 
are registered and communication via MODBUS or OPC is maintained.  

 

Select the Oscilloscope window on the VCM-3 Homepage 

1 

The oscilloscope shows the time waveform from all sensor signals. When tapping each of the 
accelerometers you can check whether the respons from the accelerometer appears on the expected 
channel. The update rate of the display can be adjusted so it is possible to tap a group of sensors in a 
certain sequenceand then check the result afterwards.
