  • Page 5: Introduction

    Rotation of the vane indicates yaw errors and provides output signals relative to the fixed vane base. The IceFree3™ is reliable in heavy and light winds. It is rugged enough to accurately measure winds in excess of 90 meters per second (200 miles per hour), yet its low moment of inertia allows it to respond to winds as low as 2.0 m/s.

  • Page 8: General Sensor Information

    The IceFree3’s self-regulating feature increases its reliability, insuring that the head does not reach excessive temperatures. The IceFree3 heater is powered by 24 volt power, AC or DC, making it compatible with a wide range of remote site equipment. An optional 120/240V - 24 VAC transformer is also available.
  • Page 9 Sensor Maintenance The bearings used in the IceFree3 sensors will last a minimum of 2 years. Sensor bearing life is variable and depends upon the amount of exposure to salinity, dust, moisture, icing, vibration, and other environmental factors. These factors independently, or in combination with each other, may reduce the bearing life. Routine maintenance should be considered at 2 year intervals.
  • Page 10 FG# 2443, 4102, 2650, 3291, 3448, 2848 NPN Output Circuit Operation The IceFree3™ yaw vane has four output signals, each centered on one of the four cardinal directions. The outputs are open-collector type; they sink current to signal ground when active and are high impedance when inactive.
  • Page 11 Interpreting Output Signals – 4 Channels The diagrams and table below indicate when each of the four outputs is active (1) or inactive (0) for each relative direction the nose is pointing. For example, if the vane nose is pointing 55 degrees relative to the base, the VR output (blue wire) and VR90 output (orange wire) will become active.

  • Page 16 FG# 2807, 3057 PNP Output Circuit Operation The IceFree3™ Yaw Error sensor has one output signal. The output is “PNP”, which means an active output sources current from the sensor supply to the load on the output. Typically, the output is used by connecting the output to a grounded load such as a relay or optical isolator in the turbine controller.
  • Page 17 Interpreting Output Signals – 1 Channel The diagrams and table below indicate when the output is active (1) or inactive (0), for each relative direction the nose is pointing. For example, if the vane nose is pointing 205 degrees relative to the base, the VR output (blue wire) will become active.
