The following wiring diagrams show how to wire
the WA25 sensors with WAC155:
- No external operating voltage
- Low-current operating power needed
| If you have WA25, you configure WAC155. See Configuring WAC155 for WA25. |
No external operating voltage
The following figure shows the simplest wiring for the WA25 series wind sensors with Vaisala Mains Power Supply WHP25. WAA252 supplies WAC155 with the operating power (+12 Vout to X2/3). No external operating voltage is applied to connector X2. The expansion connector required for high-current wiring is included in the WAA252 accessories.
| WHP25 is sold only as a spare part. |
Low-current operating power needed
The following figure shows the WA25 wiring for applications where low-current operating power is needed also when heating power is not available. The expansion connector required for high-current wiring is included in the WAA252 accessories.
| WAA252 accessories include the expansion connector required for the high current wiring. |
