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.
