Wave device SW input not working

Modified on Tue, 6 Aug at 2:49 PM

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:


Verify Switch / Button connections:

Probable cause: Improper connections or loose wiring.

  • 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.


Check Switch/Button Functionality:

Probable cause: Faulty or damaged switch/button.

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


Inspect Parameter Configuration:

Probable cause: Incorrect parameter settings.

  • Review the device's parameter no. 1 - 4 settings and ensure proper values (value 1 or 2 for switches, 0 for buttons).
  • Ensure that Parameter No. 17 is set to value 0, which defines the behaviour of the device after a power supply failure.
  • Confirm that the parameter settings allow for input from the switch/button to control the output.


Check Device LED Indications:

Probable cause: Active alarm or error state.

  • 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.


Perform Remote Device Reboot:

Probable cause: Software glitch.

  • 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.


Reset to Factory Settings

Probable cause: Corrupted configuration or settings.

  • If all else fails and the LED light remains off, consider performing a factory reset following the procedure in the article.
  • Note any changes in LED behaviour after the reset process is completed.


Contact Technical Support

Probable cause: Undiagnosed problem.

  • 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.
