The NCV Communication Test will scan the nozzle bus to detect if it can communicate with all NCVs on the boom. Run this test first if the system is experiencing NCV errors as it will point you in the right direction for one or more bad NCVs or connections. It will measure how long it takes for a message to go through the nozzle bus and then back on the return channel.
If the test has a good result, you will see the number of NCVs on the left and right circuit, the latency for the message through each circuit, and the overall tip-to-tip latency.
If the test shows one or more NCVs with no communication, you will see where communication stopped and resumed. Use this information to locate a potential problem with the NCV or cable.
Refer to the calibration and operation manual for troubleshooting steps for offline NCVs.
One extra thing you can do is check the DTCs page and look for an “NCV Unexpected Reset Single” error. This error is telling you that an NCV went offline for a certain amount of time, so you should inspect the NCV and connection for proper voltage or damage.
