New user. Problem tzt2

[Igna_78]

Hello!!

I have a 8.40 Starfisher in which I have assembled a new equipment:

Furuno sounding line

12” TZTOUCH screen

DFF1-UHD module with airmar B265LH chirp transductor

DFF3D with airmar B54 transductor

HUB-001 (switchboard)

computer with Timezero

CMAP Cartography


I have a lot of problems with the sounding line. The DFF3D module doesn’t go ahead longer than 10 meters, the movement sensor has been configured recently to try to solve the problem.


The DFF1-UHD has a lot of problems to mark the depths, the high frequency doesn’t go ahead longer than 70-100 m. and the low frequency, although it draws in 1200 m., has problems to draw the depths and it doesn’t mark the numeric meters although it is in manual scale. It only mark fish until 100 meters.


Configuration: manual transmission to 20. Manual scale. No acufish. No dephts detection.


Cutter and gain configuration, according to depths and sea circumstances. Tvg 5until 200m. Tvg 3 between 500-800m.


I was guaranteed that DFF1-UHD marks depths until 1200 m. and fish until 800 m. and DDF3 marks depth until 300 m and 3D until 200 m. How is the capacity of the sounding line to mark the fish in meters?


I have a lot of problems to mark the depths and the sounding line quality to mark the depths works sporadically.


To 10m of depths and manual depth, the low prescience do 6 depths and high frequency only 2 depths . I am waiting for a checking on the transductor state with TDT 1000.


Another doubt, can I have problems with the pitching although I have connected the bottom heaving correction? Is it necessary use the pitching sensor in a 8 m boat when I am fishing in a tidal wave? Is it possible to correct the pitching with a PG-500 compass or is it necessary a SC-30 type satelital compass?


Thank you

You don't list a DFF3 in your equipment list but lower you talk about the DFF1-UHD, DFF3D, and DFF3. Do you have all three of these units? What freqs are you using on the DFF3?

Do you have photos of the installation and photos of the sounder screens in operation?

The DFF3D has a pitch and roll sensor for it's use inside the transducer. Heaving functions requires a suitable Sat Compass. You can not get heaving information from the PG500 compass.

Have you spoken to your distributor (Furuno Spain)?
What did they say?

 

[Igna_78]

When I talked about DFF3 I meant DFF3D. I don't have DFF3. I have
DFF1-UHD y DFF3D. Both malfunctioning. Is it necessary a satellite
compass for the DFF1-UHD with 265lh? Can the 265lh have problems in
pitching and rocking?
If I use a satellite compass, is it necessary introduce configuration
data of the 3D? I understand that the PG-500 doesn't send information
to the sounding line, do it to the pilot?
Can the new SCX20 be installed with the TZT2?

I am waiting for the testing of the TDT1000 by the distributor to
check how the transductor is working. I think that the transductor or
the box are bad. I prefer do not to talk about Furuno Spain.

I send you photos when the transductor with will be revised.

 

[Igna_78]

Both transductors were checked with tdt 1000 and they seem fine.
I attach photos.

The DFF3D doesn't work deeper than 10 meters, they think that it is a
pitching problem, but it should be corrected with the box internal
sensor. Firstly, Furuno told me that it wasn't necessary a transductor
configuration and a sensor for a small boat (8 meters), but then they
did a configuration, but it didn't work. Also the told me that it
wasn't necessary an earth wire. Now, they think that connecting the
SCX-20, the problem will be solved and they can avoid to do the
configuration. I think that they have installed a few DFF3D in Spain.
The distributor thought that the transductor was bad, but the tdt
test verified that it is in range

The b265, I have problems with AF.
The BF improves the functioning with the adjust and overall with the
tvg in 3 and 500 meters.
It seems that AF doesn't have too much power , it doesn't mark depth
deeper than 100 meters. It is very noisy/dirty. Can it be a box fail?

So looking at some of your pictures, are each of those units grounded properly to earth grounds, using the wing nuts off of the TZT2, DFF1-UHD, and DFF3D.

Looking at pictures of both the UHD and DFF3D, it looks to be more like noise/interference issue and not so much of a "heaving" issue. Could also be some turbulence. Are you in rough waters during the pictures of the DFF3D?

 

[C-Bass]

I would agree with Kicker,

For the DFF1-UHD and also the DFF3D, it does appear that there are signs of turbulence, the large breaks in the bottom shown in the photos would indicated this.

The DFF1-UHD as Kicker mentioned does appear to be noisy.

We need to see pictures of the installation of the DFF1-UHD, specifically photos showing how the transducer is wired into TB3 and TB4. Also the transducer cable should have 3 shield/drain wires (bare wires) please make sure the photo shows where those shield/drain wires are terminated.

The photos were taken in calm water. My boat doesn't have earth wire. I was told that it was not neccessary to connect earth wire. Is it necessary? Is it posible that there are problems with the adjust menú configuration of the sounding line? Is it neccessary a satellite compass? The high turbulence that you said is the sounding line looking for the depth, changing of configuration. I will take photos as you point out. Thanks

 

[Igna_78]

You were right. I have a lot of interferences. I turned off the engine and the computer and the sounding line got better. I talk with my distributor to install the earth wire. As soon as I have the new screen captures, I will send you them. Thanks

it is necessary to put ferrite filters at the entrance of boxes and tzt2???

 

[Johnny Electron]

You should not need to have EMI filters. It appears you have some noise on the boat along with water turbulence. I recommend you work with your local Furuno distributor. As documented here on the forum, the grounding of units are very important especially for the DFF3D multi-beam, because of the large coverage and collection of information. The transducer and cable grounds should be grounded properly under the metal hold down as it enters the machine. For the DFF1-UHD, do not connect the orange wire. Disconnect it if you did. If you have good grounding to the units, you should seek out the noise source. Noise can travel on bad grounds. Lack of grounding isn't recommended. For water turbulence, the transducer location might need moved. If you have photos of up and down the hull where it was mounted, in relation to other items on your hull, it might be good to post photos so SNIPS and C-Bass can look at the placement.

public is also that it seems a good image

 

[Johnny Electron]

Which transducer is used for which sounder?
The one transducer doesn't look level with the waterline. They are very close together and likely to be very turbulent.
