Problem Solution
Product is not communicating over Modbus daisy chain • Check the unit Modbus address to ensure that each device on the daisy chain has a unique address.
• Check Parity.
• Check the communications wiring.
• Check that the daisy chain is properly terminated.
RX LED is solid • Check for reversed polarity on Modbus comms.
• Check for sufficient biasing on the Modbus bus. Modbus physical specification calls for 450-650 Ω biasing. This is usually
provided by the master.
The main board has a fast flashing amber light • Verify ribbon cable connectors are inserted in the correct orientation.
• If cables are correct, reset main board to re-initialize product.
The main board has a slow flashing amber light • One or more channels is clipping. This can be caused by a signal greater than the split-core size or 277 V L-N, or by a signal
with high THD near the gain stage switching points (1.5 A and 10 A).
The main board has a flashing green light • Everything is wired properly and the main board has power.
The main board is a flashing or solid red light • Light may be red briefly while device powers up.
• If light is red for more the 60 sec. device has encountered a diagnostic event. Contact technical support.
Split-core product is reading zero for some values • Device was unable to read split-core adapter boards on power up. Verify adapter boards are connected.
• Verify ribbon cable connectors are inserted in the correct orientation.
• Reset main board to re-initialize product.
Power factor reading is not as expected • Verify voltage taps are connected in appropriate phase rotation.
• Verify phase rotation of breakers (firmware rev. 1.012 or higher allows for custom rotation if needed).
Current reading is not as expected, or reading is on different CT
number than expected
• Verify ribbon cable is fully seated and in the correct orientation.
Current is reading zero, even when small currents are still
flowing through circuit
• The product cuts off at 50 mA, and will set the reporting register to 0 mA for currents near or below this range.
E3x Config Tool returns Modbus error on read/write • Verify using the latest release of E3x Config Tool as older versions may not support all features in current product firmware.
