There is a 2-color status LED on the Vaisala Serial Transmitter WAC155 component board. The LED flashes green when the operational status is OK, and red when there is an error condition. The LED is activated for 5 minutes after the transmitter is switched on. The LED is also activated when the service connection is open.

The red LED does not indicate the error type. You must establish a service connection to find the cause.

Data and service connections are provided over an RS-485 serial bus or service connector X5.
