Troubleshooting
March 2019
Cause
There is a checksum mismatch in the core processor's program section. This alert applies to the standard core
processor only.
Recommended actions
1. Ensure that all wiring compartment covers are installed correctly.
2. Ensure that all transmitter wiring meets specifications and that all cable shields are properly
terminated.
3. Check the drain wires.
a) Verify that the drain wires from the 4-wire cable are properly landed.
b) Verify that the drain wires are landed outside the core processor housing.
c) If the drain wires are landed inside the core processor housing, cover them by the foil shield for
their full length until they land under the ground screw.
4. Ensure that all meter components are grounded properly.
5. Evaluate the environment for sources of high electromagnetic interference (EMI) and relocate the
transmitter or wiring as necessary.
6. Reboot or power-cycle the transmitter to see if the alert clears.
7. If the alert persists, replace the core processor.
17.12.15 [026] Sensor/Transmitter Communications Failure
Alert
Sensor-Transmitter Communication Error
Cause
The transmitter has lost communication with the core processor, or there have been too many
communications errors.
Recommended actions
1. Check the wiring between the sensor and the transmitter.
2. Verify the power to both the transmitter and core processor.
3. Cycle power to the transmitter.
4. If the alert persists:
a) Replace the core processor.
b) If that does not solve the problem, restore the original core processor and replace the
transmitter.
c) If that does not solve the problem, replace both the transmitter and the core processor.
