Warning If the switch is grounded to the protective earth (PE), checks can be done without turning off all power supply equipment. If not grounded, ensure all power supply equipment, including motor voltages connected to the DAQ, is turned off. Wait at least 10 minutes before performing any maintenance work to ensure safety.
If your Fitlet gateway goes offline unexpectedly (not during a planned maintenance stop), follow these steps:
1. Power Cycle
Unplug the gateway from the power supply for at least 10 seconds to reset it.
2. Check LED Status
Power LED Off: The gateway isn't getting power.
Ensure the connector is secure.
Test the installation wiring using a certified multimeter. Place one probe in a connector of the power supply and the other probe in any available port of the gateway.
If LED 1 is off, the cloud connection is lost. To fix this, disconnect the gateway from both the power adapter and the switch. Reconnect after the LEDs have been off for 10 seconds.
If LED 2 is yellow, the wireless signal is weak. To improve it, adjust the magnetic foot antennas to enhance signal strength.
3. Access SAM4 Setup Tool
If inaccessible: The gateway is frozen—perform another power cycle.
If accessible: Download a support bundle from the help tab.
4. Check Connectivity
For mobile connections, go to Connectivity > Mobile and adjust antenna if the signal is weak.
5. Contact Support
