The status indicator LED is located on the
component board under the junction box cover.
- The LED flashes green, if the self-diagnostics are completed without errors.
- The LED flashes red, if there is an error.
An error can be caused by a sensor malfunction, an erroneous installation or configuration, or a combination of these. To diagnose the problem, use the service command ERRS over the service connection.
If WAC155 signal cable is connected to a data
collection system and the system is switched on, make sure that the wind readings react
correctly:
- To test the anemometer, rotate the cups manually.
- To test the wind vane, hold the vane at a few fixed angles and verify the data.
