DataStreams: | nsamettiptwrC2.a1, nsamettiptwrC2.b1 |
Description: | Due to unknown wiring differences and pin changes by Vaisala to their Wind Speed and Direction sensors, a power feedback into the QLI data collector occurred. This caused an overload which shut the QLI data collector down. Once trouble shooting pinpointed the power feedback, wiring diagrams were created and the differences were found. Wiring was changed to prevent and remove the power feedback. |
