6.   Commissioning

  

At the first commissioning of the M-Sens 2 it is necessary to calibrate the sensor. 

 
Please consider:

 

Correct connection between sensor, C1-box and transmitter.

 

Correct installation of the sensor in respect to the wall thickness.

 
In case of negative results in spite of consideration of the points as stated above, please contact SWR. 

 

Commissioning of the M-Sens 2

After the delivery the sensor is 

not calibrated to the product(s), 

so each calibration and parameterization 

has to be executed during the commissioning. Therefore it is necessary to assign the measured moisture to 
the desired display and to the initial value. The menu functions are very self-explanatory. In the following a 
short introduction to the menu overview:
Changed values are confirmed and saved by pushing the arrow button. To abandon the menu without saving 
the changes push the C-button.  

Starting the menu 

Entering the menu takes place by pushing 5 s the invisible key lower    

  

  

 

right corner of the touch screen panel. 

Basic function 

For the measurement and display of the moisture in %, there 2 - 3 moisture    

  

  

 

measurement executed with known and different moisture values. After having  

  

  

 

entered the according moisture values by the panel, the system calculates the  

  

  

 

moisture in % on the basis of those measurement values.

  

  

 

Hereby the basic function is initiated.

Adjustment 

The menu point 1 “products” can be used for every of the 4 possible products.

 
Alarm 

 

Alarm can be determined for every product in the menu point “measurement   

  

  

 

range”.

 
Analogue outputs 

The analogue outputs can be defined in menu point 5. They can be adapted to  

  

  

 

the operator’s requirements (e. g. 0 - 20 mA).

   

 

The output value (current) is assigned to the measurement range. 

    

   

   

 

Standard   MIN  =   4 mA 

   

 

  

   MAX  = 20 mA 

    

 

   

 

The measurement range filter serves to the adjustment to slower measuring    

   

 

devices or to continuous output at the analogue output.
