Troubleshooting Guide

If your Loncel device is not behaving as expected, follow these general troubleshooting steps.

Communication Issues

Device Offline in Cloud

If a device appears “Offline” on the Loncel Cloud dashboard:

WVC-LTE

1. Check Power: Ensure the device has power.
2. Check Signal LEDs: Observe the status LEDs on the device.
   • Green: Connected.
   • Red: Disconnected.
3. Inspect Antennas: Ensure all antennas (LTE, 915MHz) are securely tightened and have a clear line-of-sight if applicable.
4. Reboot: Power cycle the device by disconnecting the power for 10 seconds and reconnecting.

WVC-GS

1. Check Battery: Verify battery voltage (should be ~3.6V). WVC-GS radios use a high-capacity 8500mAh Li-SOCl2 battery. Voltages below 3.3V are considered low and may cause radio faults.
2. Line of Sight: Ensure there is no excessive foliage or new obstacles between the radio and the Base/Repeater.
3. Inspect Hardware: Check for damage caused by livestock or extreme weather (lightning, intense rain).
4. Ping Test: Use the Ping function in the dashboard to manually trigger a communication test.

RMU

1. Check Power: Ensure the RMU is connected to a stable power source.
2. Check LTE Connection: Press the Test button on the RMU to initiate a manual data transmission and show the system status menu.
3. Reboot: Power cycle the device by disconnecting the power for 10 seconds and reconnecting.

Sensor & Valve Issues

Analog Input (4-20mA) Reading 0

If your RMU or Gateway is reading 0mA for a sensor:

1. Check Wiring: Verify the sensor is wired correctly to the terminal blocks.
2. Measure Loop Current: Use a multimeter to verify if the sensor is actually outputting a current.
3. verify Power: Ensure the 4-20mA loop has the required excitation voltage (usually provided by the RMU or an external supply).

Valve Not Opening

If a WVC-GS Valve Radio is not triggering a solenoid:

1. Manual Override: Try to trigger the valve manually via the Loncel Cloud interface to rule out scheduling issues.
2. Check Solenoid: Inspect the wiring to the latching solenoid. Ensure the solenoid is a DC latching type compatible with the radio output.
3. Check Signal Strength: Verify the radio has a strong link to the Base or Repeater radio.
