Does a WindSensor P2546A anemometer require an iPack to work? How do I wire a WindSensor P2546A?

When connecting a WindSensor P2546A anemometer to the SymphoniePLUS3’s preconfigured channels (1-3, 13-15) an iPack is required. It should be wired:

• Brown to Excitation
• White to Signal

This is because these channels use the 12V excitation from the iPack to create pulses that get fed into the channel as the sensor’s Reed switch turns on and off.

When using the SymphoniePLUS3’s flex channels (4-6) with a Digital Anemometer SCM no iPack is required.

This configuration it should be wired:

• Brown to Signal
• White to Ground

When using a Symphonie or SymphoniePLUS logger, counter channels (4-6) with a Digital Anemometer SCM, no

iPack is required. This configuration should be wired:

• Brown to (-)
• White to (+)

The Digital Anemometer SCM routes the data logger’s 5V through the sensor’s Reed switch.
