[TG] [TG11] ST60 Replacements

[Tom - Raymarine - Moderator]

Hello rxcraymarine,

A new display can use the existing masthead unit and cabling, or if you needed to replace the masthead windvane then a new windvane can use the old masthead connector and cable down the mast. The connections to the display are identical. There are two things to take note of:

• If you're using an old-style ST50/ST60 windvane (squared-off vane feather and cups, alloy cylindrical body between the vane and cups, as opposed to new-style which has rounded cups and vane and a plastic egg-shaped body between the two) with a newer display, you need to make sure that the wind speed calibration factor is set to the minimum that the display software allows (either 0.7 or 0.75 depending on version) rather than the 1.0 that was used for older windvanes. This is because the new windvane has better bearings and spins faster in the same windspeed.
• If you're fitting a new windvane to the old alloy masthead block, you need to remove the O-ring seal from the seat of the connector. This is because the new windvane seals with an O-ring around the exterior of the shaft, compressed by the ferrule, instead of inside the connector, and the interior O-ring can prevent the new windvane from fully seating home into the connector.
• Whenever you replace a windvane on an existing display, you should do a Factory Reset on the display in order to re-do the windvane linearisation process. The reset procedure is in Dealer Cal, described in the back of the display handbook.
