There is no output signal from the NK-2.4Y?
- Check the LINK status: if the LINK terminal shows a steady LOW signal, it is linked. If communication is out of range, the link terminal will show LOW/HIGH signal. A steady HIGH signal indicates 'module not working'.
- Modules not paired: If the pairing procedure was not successful, the input and output modules will not communicate. Perform the pairing procedure again.
- Input Signals applied before applying power: For safety reasons, if any input changes are applied before the input module is switched ON, the outputs will not respond to the changes.
