Output signal  
Signal type Push/Pull (compatible with NPN or PNP inputs) Current loop, 4 to 20mA, sourced by the sensor
Transfer function Two yaw-error signals
  • VR (left / right)
  • VL90 (front / back)
    see manual for details
  • 4 to 20 mA corresponds to 0° to 360° in clockwise (CW) direction
  • For turbine control, orient so that 180° corresponds to on-the-wind
Accuracy
  • +/-1.8&deg (0.5%)
  • factory calibrated at 180&deg (on the wind) +/- 0.5&deg
