I'm having trouble with a frequency converter. The data sheet is given here.
I set the converter for universal frequency input and voltage output. These can be configured by DIP switches. The diagram from the data sheet is given as below:
And here is how I do the wiring:
I use a 12V power supply, and as an input I couple 0/10V pulse train by using a function generator to the terminals 2 and 3 above. The pulse train is exactly 0..10V and I followed the advice on section 8.7 at page 20 to set the pulse properly.
I checked the DIP configuration too many times and I'm wondering whether my wiring is wrong. Just to make sure here is my DIP config:
For SW1: ON ON OFF OFF ON ON
For SW2: OFF ON OFF OFF OFF ON OFF ON OFF OFF
According to the data-sheet if I configure the DIP switches as above I should get 0 to 5V voltage output mapped from 1Hz to 300Hz frequency input range from a pulse train input.
But I get a constant 17.6V output by the voltmeter whatever the input frequency is, it is constant even though I don't hook up any input. The RED indicator flashes with 2.8Hz which data sheet says(at page 21) it happens when the "Sensor fault or invalid DIP switch configuration".
I spent several hours but no luck. Is the connection from the function generator to the terminals 2 and 3 correct?
