WS150 Digital Wind Speed/Direction Instrument 4.25 Inch square Digital Wind Speed and Direction instrument. the WS150 is supplied with a low drag masthead and 100 Feet of masthead cable. Has NMEA output that can be connected to the RP150 NMEA repeater for dual station operation off one transducer. NMEA output can also be connected to any STANDARD HORIZON GPS to show wind speed and directon on the plotter display. WS150 WIND SPEED Standard Horizon's WS150 wind instrument has everything the avid racer could demand, including digital display of apparent wind speed and direction (true wind speed and direction is available when connected to an SL150). As an additional aid there is a digital representation of an analog dial showing the wind direction relative to a 360-degree reference. The WS150 also features a user settable "maximum wind gust" alarm, which is great for timing sail changes. The transducer is a low mass with a long boom to minimize the affects of wind turbulence. GREAT DISPLAY The WS150 features a high contrast LCD display with big bold digits that are easy to read in any light condition. A rugged non-corrosive case features a curved lens that reduces glare. Backlighting optimizes night viewing. UNCOMPLICATED INSTALLATION Installation is a breeze without the use of special tools. The WS150 is a square 4-inches instrument flush mounts for custom looking installations. The case protrudes less than 1 inch from the bulkhead and only 1-inch into the surface. Of course, the WS150 instrument outputs reliable NMEA data, for interface with repeaters and other electronics.

Wind instrument loses its linearization

It should be noted that the masthead unit for the wind speed/wind direction instruments must be linearized first and then calibrated. The ideal time/sequence to do this is before mounting the masthead unit by plugging the mast unit directly to the back of the display unit. The linearization and calibration can then be performed very accurately. After which the masthead unit can then be taken up the mast and put in place. Should there then appear to be a problem in the wind angle or wind speed the most common cause of the problem will be damage to the mast cable or incorrect connections running back through the boat (connections in the junction box). The linearization/calibration information for the unit is stored in the NVM (Non volatile memory). It is very unlikely that the NVM would fail and delete it's contents. It is possible that the NVM can get corrupted if there are low power levels on the boat, it only takes a single bit of data to be corrupted to vastly alter the linearization constants. If this happens the linearization/calibration will have to be performed again.

Erratic Wind Speed Readings

The most likely answer to this problem is that the masthead bearings for the wind direction are slowly stiffening over time due to water intrusion. This will cause the MU (masthead unit) to give readings that are way out. For this type of complaint it is best to take the display as well as the MU to your nearest STANDARD HORIZON dealer so that the problem (if any) can be resolved as quickly as possible. Another common cause of highly erratic wind direction readings is that the connections at the base of the mast where the cable is cut and put into the junction box has become corroded or loose or has lost contact. The white and brown wires in the masthead cable are the wires that carry the wind direction information and most typically the ones that will be at fault if all other avenues have been checked.

Instrument gives readings that are way out

The WS150 can both display true wind and apparent wind. The true wind calculation is made given the speed of the boat and the current (apparent) wind angle to calculate the true wind angle. However if the speed-reading is way out due to a faulty paddlewheel, or if the speed input is not connected at all then the calculations will give a true wind reading that is incorrect. Check that the speed-readings are correct and that the speed input is connected and if they were using true or apparent wind. This could be a problem with the MU (masthead unit) where bearings for the wind direction are slowly stiffening over time due to water intrusion. This will cause the MU (masthead unit) to give readings that are way out. For this type of complaint it is best to take the display as well as the MU to you?re nearest STANDARD HORIZON dealer so that the problem (if any) can be resolved as quickly as possible.

Wind direction indication does not change even though wind vane moves

The problem could be in the masthead assembly. One-way to check this is to locate the junction box and check the voltage between the white wire and ground, and the brown wire and ground. If the masthead assembly is functioning the voltage on each wire will be anywhere between 1.5 volts and 3.25 volts, with a difference between the two wires of about a volt (for example if the white wire reads 1.5 volts the brown wire should read 2.5 volts). Usually if the masthead transducer has stopped working both the brown and white wire will measure about 2 volts.

How do I turn the power on and off on my wind instrument without having to disconnect it from the battery?

In a typical wiring situation the instruments are wired directly to an accessory panel or breaker. When power to the boat is turned on the instruments are designed to turn on automatically as well, making an on/off switch on the instrument unnecessary. It is possible to wire in an external on/off switch in-line if access to an accessory panel or breaker is not available.

My WS150 loses it's linearization

It should be noted that mast head unit for the WS150's must be linearised first and then calibrated. The ideal time/sequence to do this is before mounting the mast head unit by plugging the mast unit directly to the back of the WS50 or WS100. The linearization and calibration can then be performed very accurately and when happy with the quality of the information the mast head unit can then be taken up the rig and put in place. Should there then appear a problem in the wind angle or wind speed the most common cause of the problem will be damage to the mast cable or incorrect connections running back through the boat. The linearization/calibration constants for the WS50 are stored in the units NVM (Non volatile memory). It is very unlikely that the NVM would fail and delete it's contents - several people have become erroneously convinced that this was the case. Furthermore, it is also very unlikely that the unit will corrupt only the data containing the linearization constants in the NVM and nothing else! However it is possible that the NVM can get corrupted if there are low power levels on the boat, or if the instrument is subjected to a large amount of radio interference. It only takes a single bit of data to be corrupted to vastly alter the linearization constants.
