Description
Fault Code (4)3 is displayed when no signal has been received from the harvi device. This typically indicates a communication issue or a problem with the harvi's configuration, wiring, or monitored power cable. The error will appear only if no signal has been detected for over 24 hours.
Checks to Perform
1. Confirm the harvi LED is Blinking
- Check the harvi unit and observe its LED indicator.
- A blinking LED indicates that the harvi is transmitting signals.
If the LED is Not Blinking:
a) Check Sensor Connections
- Ensure that the sensors are securely clamped around the monitored cable.
- The sensor clamps should fully encircle the cable with no gaps or loose connections.
b) Verify Terminal Connections
- Confirm that the sensor wires are correctly connected to the terminals inside the harvi.
- Ensure that all connections are tight and in the correct orientation as per the installation manual.
2. Check Monitored Cable Power Status
- harvi may stop transmitting if the monitored cable has no active power flow.
- Verify that the monitored cable is live and drawing current.
Post-Check Actions
- Once the necessary adjustments are made, observe the harvi LED for blinking activity.
- Allow time for the harvi to re-establish communication with the system.
- If the issue persists, consult the installation manual or contact technical support for further assistance.
Additional Notes
- Preventative Tip: Regularly inspect sensor clamps and connections to ensure reliable operation over time.
- A temporary loss of signal may not trigger this error unless the issue persists for over 24 hours.
By following these steps, you can identify and resolve the cause of Fault Code (4)3 effectively, ensuring reliable communication between the harvi and the system.
