Modified on Tue, 18 Jun at 10:40 AM

If the device is not reacting to the SW input, indicating that the connected switch/button does not have any effect on the output (not valid for the Wave i4 and Wave i4 DC), follow these troubleshooting steps to address the issue:


  1. Verify Switch / Button connections:
    • Ensure that the switch/button is properly connected to the designated SW terminal on the device.
    • Check for any loose connections or wiring issues that may be affecting the input signal. 
  2. Check Switch/Button Functionality:

    • Test the switch/button independently to confirm its functionality.
    • Verify that the switches/buttons are not damaged or stuck in the pressed position.
  3. Inspect Parameter Configuration:

    • Review the device's parameter no. 1 - 4 settings and make sure that the proper value is set for the connected switch (value 1 or 2), button (value 0)
    • Ensure that Parameter No. 17 is set to value 0, which defines the behavior of the device after a power supply failure.
    • Confirm that the parameter settings allow for input from the switch/button to control the output.
  4. Check Device LED Indications:
    • Observe the LED indicators on the device to determine its current status.
    • Be aware of the any alarm signalisation which can prevent the use of the switch/button connected to the SW input-s.
    • If any alarm signal is active, first consult our guide to verify the alarm. Next, perform a power cycle on the device to reset the alarm. Finally, verify the state of the switch or button.
  5. Perform Remote Device Reboot:
    • Attempt to initiate a reboot remotely (Parameter No. 120 set to 1)
    • Monitor if the device responds to the switch/button input after the reboot process completes.
  6. Reset to Factory Settings: 

    • If all else fails and the LED light remains off, consider performing a factory reset.
    • Follow the procedure outlined for factory reset article.
    • Note any changes in LED behaviour after the reset process is completed.
  7. Contact Technical Support: 

    • If the issue persists after performing the above steps, open a ticket.
    • Provide detailed information about the troubleshooting steps taken and any observations made during the process.
