I went out sailing today and when I turned on my navigation equipment, but True Wind Speed data was missing as was my Boat Speed which of course then never provided any data for the AWS and TWD etc.

Has anyone had an issue like this before and if so, how did you rectify it? I have just updated the H5000 Hydra CPU with the latest software, but haven't had a chance to see if it makes a difference.

Wanted to find out if there is anywhere in the system that I can reset before having to call in the B&G guys.

Thanks!

Often powering the navigation system off, and then on again, at the circuit breaker, will resolve these issues. 

I’d also go  into your ‘network settings’ on your plotter, and have a look at the device list. See if the speed and wind sensors appear in the network, and you can also check their function here as well. 

I’ve found that when my plotter is recording ‘tracks,’ after a time the system becomes quite buggy. Stop recording tracks and delete your olds ones. At least for me, this improves performance. And after updating software, the default settings in the plotters start these tracks all over again, in the background, consuming memory and slowing everything down. I have to go in, cancel the tracking and deleting the recorded tracks. 

Let us know how you resolve this and good luck.

Thanks Kipwrite, I'll try all the suggestions and let you know!

Cheers!

Is the TWS showing zero or just a mirror of the AWS?
Check the speed impeller is clean and not fouled causing that to show zero speed.
As mentioned elsewhere I sometimes find I get network anomalies when I switch the VHF on after the main navigation.  One occasions I lose the wind instruments (both true and apparent) which requires a network reboot (navigation power off and on) to reset.

I also had random restarts of the Zeus when I had over two seasons (2,500Nm) of tracks.
Even though system memory was only 30% used it does not cope well with excessive tracks.
I now clear my tracks at the end of each season.

Thanks for the reply! I’ve checked the impeller and all is good. There is no TWS/TWD/AWS/TWA and the tide is shown as the SOG.
I will clear the tracks to see if that changes anything and will go from there.

I think the clue is in the fact you just updated the Hydra software.  If that is when your problem started it is most likely the cause. 

There are a lot of settings available to you from the web interface to the Hydra (found with either a wifi or network connected PC or tablet).   These include set up of sources for all the data points you list.  The Hydra calculates true wind.   You need to check these settings.

I had the same problem with a new (2019) B&G at handover in Greifswald.  Fortunately the B&G tech was nearby and resolved the issue by going into the source menu and clicking on the address for the wind transducer.  He could not explain why the signal was lost in the first place.

Hope this is of some help.

To expand a little on Kodiak's comments....

I've found that when you power up NMEA 2000 devices on the network you sometimes get what *FEEL* like address conflicts.   These cause devices to NOT show on the network.   Why is a mystery to me (and apparently B&G) because I've had their best on my boat and they couldn't find a cure outside of the Bill-Gates-Cure-All-For-Windows-PCs (turn it off and on again). 

The data shows as zero because the display source for many items like wind is the CPU (if you have one), who then gets it from the real device at the top of the mast.   It uses that data to calculate items like wind direction differently.  For example,  as the wind speed increases it accounts for mast twist and other factors.   If there is no physical source, then the data seems to show as ZERO.  Checking the source for wind it probably shows the Hydra CPU.

You need to look for the actual wind instrument on the network.  Something like a "508" or whatever.  If its there,  you can validate it's correct by looking at the data before the CPU gets it.   My experience is that if its on the net, things are usually OK.  If its not,  you don't have much choice but to try and get it back on the net by powering it off and on again...

Hi! 
I had the same issue not long ago. The problem was in the mast cable. The trick is that Wind sensor also works as terminator in Simnet hub to witch speed log also connectedб therefore, both devices disappear from the network at the same time. The easiest way is to buy a new simnet cable for the mast (the standard cable length  is 35 meters ) to climb onto the mast and try to connect the wind sensor directly or unfasten the wind sensor from the mast top and connect with any simnet cable to the simnet hub in the front bilge. Strange, the cables look quite reliable, but I already changed 2 on my boat.

We eventually found out what the problem was, but before that, we discovered a potentially fatal issue! I was away and asked a technician to have a quick look to see if he could solve the wind issue. He went scratching around and opened up the battery bay, only to find that I was undergoing a thermal runaway! Hanse wont take responsibility, nor will Victron. The B&G guys took the Mastervolt Charger away and hook it up to the international server where the head office could diagnose. They performed a firmware upgrade and after putting in new batteries, it is working the way it was supposed to from day one. (Also something I mentioned to my local dealer here, but nobody bothered to listen!)
The wind issue turned out to be a dodgy wind vane which has been replaced.
