Wiring with WHP151
| WHP151 is sold only as a spare part. |
The following figure shows WAC155 wiring with Vaisala Mains Power Supply WHP151 with heating power connected.
| WHP151 has jumpers for configuring the power output. Connect pins 2 and 3 of X5 to set the correct operating voltage and remove the jumper of X4 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 and 3 of the X8 jumper. |
