For further details on user calibration modification using the Acu-Vis 2.0 program please contact FT Technologies. 2.3 Wind Speed and Direction Filtering It is important that the system does not rely exclusively on a single wind reading for any control decision.

  • Page 12: Electronic Rotation Of The Datum Direction

    Section 2 Functional Description 2.4 Electronic Rotation of the Datum Direction The datum direction of the sensor can be offset electronically by using the CF command (Section 6.4.6). This facility can be used to adjust the datum direction in case of any mechanical misalignment within the mounting arrangement.

  • Page 13: Acoustic Temperature

    (between sensor body and ambient airflow), extreme humidity levels and low wind conditions (below 5m/s) may result in reduced accuracy. Caution: The acoustic temperature feature requires calibration at FT Technologies. If the sensor has had a software upgrade to 7.5 (or above) then the data will be uncalibrated and may not comply with the official specification.

  • Page 26 Section 3 Mechanical Installation & Lightning Protection Figure 17: Pipe Mount Sensor The system ensures that the base of the sensor and connector/cable are sealed inside the pipe and adaptor. This helps to protect against environmental degradation, as well as against the effects of indirect lightning strikes. The FT028 O-ring (see location in Figure 17) is fitted to provide protection to the grounding surface and additional protection for the connector.
  • Page 27 Section 3 Mechanical Installation & Lightning Protection Figure 18: Pipe Mount Sensor and Adapter (all dimensions in mm) Alignment The sensor measures the wind direction relative to the 180° rear datum feature (see Figure 19).

    Section 4 Service, Configuration & Test 4 SERVICE, CONFIGURATION & TESTING 4.1 Inspection The following checks are required to identify any signs of corrosion or damage on the sensor which may hinder its performance. It is recommended that these checks be carried out annually. Mechanical Damage: Check the sensor body for signs of damage, paying particular attention to the seals.

  • Page 38: Fault Finding & Troubleshooting

    If there are signs of physical damage and/or the sensor is failing to communicate properly, it should be replaced. Sensors may be returned to FT Technologies for further analysis if required (see Section 4.3). Warning – The sensor contains no user serviceable components.

  • Page 39: Returns

    Please contact FT Technologies for further information and advice if required. 4.3 Returns If a sensor appears to be faulty, compile a detailed fault description for each sensor, then contact FT Technologies to request a Returns Materials Authorisation (RMA) form. Please complete the form and return as instructed.

  • Page 49: Sensor Communication

    The sensor features an easy to use ASCII-based communication protocol transmitted over an RS485 serial link. The protocol incorporates checksum validation to ensure the integrity of all data transmissions. In addition to the FT Technologies proprietary protocol the sensor can output the common NMEA 0183 MWV (Wind Speed and Angle) sentence.

  • Page 50: Configuring The Sensor

    Section 5 Sensor Communication 5.3 Configuring the Sensor All user parameter settings are stored in non-volatile memory and are retained when the sensor is switched off. When the sensor is next switched on (or a user reset command is sent) the sensor will revert to these settings. The sensor can therefore be configured prior to final installation if required.

In addition to the calibration table, there is provision for a user-defined text string of up to 32 characters which is stored together with the table.

  • Page 57: Timing Constraints

    Section 6 Parameter Settings 6.3 Timing Constraints When a valid command is received by the sensor input buffer, there will be a time delay whist the command is being processed.
