CHAPTER 4

OPERATION

This chapter contains information needed to operate Vaisala Ultrasonic

Wind Sensor WS425 F/G.

Power On/Off

The power switch is located in the power supply enclosure at the top

left. When turned on, the two LEDs labeled +5 V and +12 V will be

turned off if their respective supply is operational. If neither is turned

on, check the 0.25 A fuse and make sure that AC power is present.

System Operation

In normal system operation, the sensor communicates with the host

system system via two fiber optic cables. This normal state exists when

no cable is plugged into the RS-232 DB-9 connector labeled TEST in

the power supply.
