•     Introduction

The Marine Data wind speed and direction sensor may be used as a stand alone, or as part of an integrated
system as indicated above. The sensor is designed to be pole mounted externally. It is housed in a salt
resistant rugged enclosure. It provides a digital RS422 output which may be integrated in to the ships
system.

• Controls and indicators.

There are no operator controls and indicators on the sensor unit. It has been designed to interface in to a
reading device such as a MD19, MD15 or another piece of equipment designed to accept The RS422
digital input.

 •Positioning Guidelines
  Step                                              DESCRIPTION
   1     The sensor must be at least 1 meter away from any small object (i.e. a wire) and be situated away
         from any of the obstructions listed below.
   2     Before mounting the wind sensor onto the pre-installed mast, the electrical connection must first be
         made. Refer to the following pages on electrical installation for more information.
   3     The wind sensor must be mounted in a position on the ship where it is free from any air turbulence
         caused by:

             Deflected air flow from a nearby object (e.g. radar mast)
             Down force or air from a helicopter.
             Air vents and exhaust systems.
     4       The sensor must also be mounted away from any radar, radio or electrical device that radiates E.M.
             transmissions of moderate power.

         If possible, the sensor should be mounted in a radar blind spot. However do not shield the sensor as
         this will impair air flow around the sensor.
   5     The sensor should be mounted in a position where it will be possible to be serviced in the future
   6     The sensor must be carefully positioned onto the pre-installed mast.
 •Installation.

 •Controls and indicators
 There are no user controls for the sensor. There is no visual indication that the data is being transmitted from
 the wind sensor. The physical rotation of the wind vane and cups is the only indication the instrument is
 working mechanically.

 •Maintenance and Spare parts.
 The wind sensor is factory calibrated and can not be user serviced. The following items are available as parts
 for the unit and may be replaced in the field.
