Having trouble with a frequency to voltage converter for universal frequency input
For SW1: ON ON OFF OFF ON ON


You have configured "Universal Input Frequency to 0-5V". That's a relay input.
I'd would have used PNP input, but the manual is definitely not clear on this.
(as expected from Phoenix Contact)


  For SW2: OFF ON OFF OFF OFF ON OFF ON OFF OFF


1 to 300 hz, software configuration active.

You've set all the DIP switches, but you've forgot to enable dip 10, enabling the dip switches as active configuration.



New info from comment. With this sensor (Adolf Thies 4.3351.00.000) the output is push-pull. Similar to the function generator. However, you need to change the range significantly for 1082 Hz at 50 m/s (22 Hz per m/s)
Try DIP2: [ON ON] [OFF ON ON ON ON OFF] [OFF ON]
10 Hz to 1200 Hz DIP configured, 10 Hz is 1 BFT, 1200 Hz is beyond 12 BFT
