Refer to Figure 2 on page 11. 0204-041 Figure 3 Recommended Mast Length on Top of a... -
Page 15: Installation Procedure
For installation, follow the procedure below and refer to corresponding sections for details. Remove the four screws holding the cover of the WAT12 transmitter. Remove the cover. Select the current output span, as well as direction and speed scaling according to the instructions in section Jumper Settings on page 14. -
Page 16: Jumper Settings
User's Guide ________________________________________________________ Jumper Settings The loop current can be selected with the on-board jumper plugs. Several output ranges, such as 0 to 20 mA, 4 to 20 mA, 0 to 10 mA, 2 to 10 mA, 0 to 5 mA, and 1 to 5 mA, are available as user configurable options, each with factory-adjusted zero and span levels. -

For better protection against RF interference, bend the cable shield as illustrated in Figure 8 on page 17. -
Page 19: Figure 8 Cable Shield Bent Over The Plastic Sleeve And O-Ring
0206-046 Figure 8 Cable Shield Bent over the Plastic Sleeve and O-ring The WAT12 transmitter has three I/O connectors as listed in Table 4 on page 18. For the location of the connectors, refer to Figure 9 below. 0206-047 Figure 9 I/O Connectors The following numbers refer to Figure 9 above. -
Page 20: Sensor Wiring
The transmitter connects to the wind sensors with the cross- arm's standard cables through two cable glands. Through these cables the WAT12 transmitter both feeds the sensor power and receives the wind data. Plug-in type screw terminal connectors are provided both for the sensor cables and the output line cable. -
Page 21: Signal Output
Typically, only a 4-wire shielded cable is required for the line between the WAT12 transmitter and the receiving end. Two of the four wires provide the operating power for the system. The other two are for the current source outputs from the WAT12 transmitter;... -
