Figure 13 Heating Power Connection for Wind Vane Only

Wiring Examples

Figure 14 on page 25 illustrates the basic wiring when the WAA151 and

WAV151 wind sensors are connected to the WAC155 transmitter.

Heating power is not connected in the figure.

Figure 15 on page 26 illustrates wiring with the WHP151 Mains Power

Supply, with heating power connected. Note that the WHP151 has

jumpers for configuring the power output. Connect pins 2-3 of the X5

jumper to set the correct voltage, and remove the X4 jumper to provide

continuous heating power. If you connect the heating in series to both

sensors as shown in the figure, set the heating power to 38 Vrms 0.5 A

by connecting pins 2-3 of the X8 jumper.

Figure 16 on page 27 illustrates the wiring with the WHP25 Mains

Power Supply and the WA252 series wind sensors. The WAC155

operating power is supplied from the WAA252 (+12Vout, F -> X2/3).

Thus no external operating voltage shall be applied to the connector X2.

NOTE

The expansion connector required for the high current wiring in Figure

16 on page 27 is included in the WAA252 accessories
