3 Pin PC Fan Speed Display and Control

At the beginning  it was a challenge to connect a 3 pin PC fan to the Loxone  Miniserver but now I find it very easy.

First you have to set up Your digital input as a frequency input to be able reading the speed

DI_set_as_Frequency_input_1

To translate in Hz or rpm I use  the block Wind Gauge, to have the correct rpm value at the output AQ I set the:

T:Averaging – time to – (  0  ) for instant rpm display

F:Factor to – (  30  )

W:Wind speed alarm I set it up to 50 Hz beacuse my fan it was 1800 rpm (60 Hz)

with this AQ will give me for display 1800 rpm
