8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Wireless switch does not activate the relay. | Low or dead battery in the wireless switch. Out of range. Interference. Incorrect wiring of the relay receiver. | Replace the CR2032 battery. Move the switch closer to the receiver. Relocate the receiver or switch to avoid interference sources. Verify wiring according to diagrams in Section 5.1. Ensure power is off before checking wiring. |
| Relay receiver not powering on. | No power supply to the receiver. Incorrect input voltage. | Check power connections and circuit breaker. Ensure input voltage is within 85-265VAC. |
| Device connected to relay does not respond. | Device itself is faulty. Incorrect connection to the device. Overload on the relay. | Test the connected device independently. Verify the clean contact output from the relay is correctly connected to the device's trigger input. Ensure the load does not exceed 10 Amp or the specified wattage for the bulb type. |
