CONFIGURATION
DIP Switch S1
Using DIP switch S1, you can set the input values, and the values for Moving
Average Filter and Over sampling.

The moving average filter can group
values (1, 2, 4, 6) using moving window averaging to form a new measured value. In moving window averaging, the average of a fixed number of measured values is taken, whereby the oldest value is always dropped and the most recent added.

In order to smooth the measured values, an average can be formed from several measured values (1, 10, 50, 100). This process is called Over sampling. In oversampling, the average is updated every time the selected number of values is reached.
DIP Switch S2
Using DIP switch S2, you can set the output values, the output type and fault
detection.

INSTALLATION
The unit is equipped with a universal mounting foot for attachment to standard DIN style top hat (T) profile rail according to EN50022 - 35 x 7.5 and 35 x 15. The unit should be installed in a location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that generate excessive heat should be avoided.
T Rail Installation
To install the AFCM on a “T” style rail, angle the module so that the top groove of the “foot” is located over the lip of the top rail. Push the module toward the rail until it snaps into place. To remove a module from the rail, insert a screwdriver into the slot on the bottom of the “foot”, and pry upwards on the module until it releases from the rail.
