KVH-system with failed depth and speed-sensor - how to fix

Dear ladies and gentlemen,

we have following problem with a KVH-System.

After a repair because of failed bus (connector-problem between PCB and connector-plate) we tried to reconnect the system.

The KVH-Bus now is working fine.

The system has following components:
KHV-Brainbox
KHV-NMEA-Concentrator
Displays and interface: KVH-Dual, KVH-Wind, KHV - human interface-unit
depth / temperature - sensor
speed-log - sensor
wind - sensor (currently not connected!)
KVH - NMEA-comp. (currently not connected!)

Unfortunately we are not able to receive the signal from sonic depth sensor continuously. Only time by time for a couple of minutes we'll receive the depth-signal.
The other signals, such as temperature and speed we can receive on the displays.
But the speed-signal seems to work not properly. The speed is wrong displayed and changing very fast within a wide range.
Only the temperature seems to be correct displayed.

Please could you instruct us how to check the signals, delivered from KVH-Brain-Box to the sensors and the signals sent from the sensors.
How we can locate this fault?
Do you have any idea because of the reason causing our failures?

The wiring inside the ship can’t be the cause for this effect, because we connected the sensor direct with the
brain-Box without any additional wires or connectors, without any effects.
We replaced also the sonic-depth-sensor - without any effect.

Maybe you can help us with service-instructions or an oscillogram regarding the required signals and the signal-conditions on the pins of the plugs.

Best regards and many thanks in advance for your help

    Thanks for the comment, but this was not my question.

    Our problems are the following:
    we are not able to receive the signal
    from sonic depth sensor continuously. Only time by time for a couple of minutes
    we'll receive the depth-signal.
    The other signals, such as temperature and
    speed we can receive on the displays.
    But the speed-signal seems to work not
    properly. The speed is wrong displayed and changing very fast within a wide
    range.
    Only the temperature seems to be correct displayed.

    Please
    could you instruct us how to check the signals, delivered from KVH-Brain-Box to
    the sensors and the signals sent from the sensors.
    How we can locate this
    fault?
    Do you have any idea because of the reason causing our
    failures?
    Thanks
    Ingo

    Thanks,
    is there anybody who's able to provide a service-manual or who has other ideas?

    thanks,
    but I don't want a link to autocomp, I'm interested in service-manual for KVH-Brainbox

  • ingo_maier May 14, 2009

    thanks for your informations,
    but i believe there are automatically generated answers.
    These links I have found also by myself, but instead of satellite-antenna or auto-comp I'm only interested in service-manual for KVH-system such as brain-box and quadro-system.
    Otherwise I wouldn't have posted my questions to this side.
    If this forum is managed by specialists please reed the questions carefully.

KVH Autocomp 1000 A precision stand-alone heading sensor for sail, power, and OEM applications The AutoComp 1000 employs KVH’s breakthrough digital fluxgate compass technology to provide precision heading data to an array of systems, including autopilots, GPS, video charts, radars, computers, and other electronic instruments. Designed as a remote sensor, the AutoComp 1000 can be mounted in a magnetically “clean” location (e.g., away from speakers, motors, wiring bundles, and other sources of changing magnetic fields), and its continuous automatic compensation feature ensures that the most precise heading data (within ±0.5°) is available at all times. The AutoComp 1000 is fully compatible with the NMEA 0183 output standard and a universal interface card is available for use with other interface standards. Highlights: Remote sensor with continuous autocompensation ensures reliable heading data at all times Accurate to within ±0.5° Fast 10 Hz NMEA 0183 standard output compatible with other ARPA radars, autopilots, and other electronic systems; optional interface card available for other outputs Options include mounting bracket and extension cables Variants for use aboard sailboats and power vessels as well as in OEM applications

    You will have to test each capacitor and diode on the system board. It also may be the memory chip. It is hard to tell without testing each and every signal with an ohmmeter.

IMAGERUNNER 2000 SYSTEM E100


This can be caused by the following....
*When the laser scanner motor is started up, the BD input signal does not arrive within a specific period of time.
*When the scanner motor is started up, the motor rotation is too fast, and fails to reach a specific revolution within 20 sec at time of deceleration.
*While the scanner motor is rotating at a specific speed, the BD input signal cycle is not within a specific range (±2%) for an equivalent of 10 mm (print distance).
*While the scanner motor is rotating at a specific speed, the BD input signal cycle is not as indicated (±2%).
*During the WMUPR period after the power switch has been turned on or the front cover/left cover has been opened/closed, the drum unit is absent.
Possible cause:
  • The wiring is faulty (short circuit, open circuit).
  • The laser scanner unit is faulty.
  • The DC controller PCB is faulty.
  • The drum unit is not installed.
Remedy
1) Drum unit
Is the drum unit installed in host machine?
NO : Install the drum unit.
2) Connection
Is the connection of the connector (J908) on the BD detection
PCB, connector (J907) of the laser unit, and connector (J102) on
the DC controller PCB normal?
NO : Correct the connection.
3) Laser/scanner unit, DC controller PCB
Try replacing the laser/scanner unit. Is the fault corrected?
YES : End.
NO : Replace the DC controller PCB.

Good luck!

I have an crack in my phone that is cutting off the words on my phone


Crack as in the display? If so not much you can do, except replace. Do opt for the cheapest handset though, even if it is not badged KVH. Companies like KVH and Sailor use the same products branded differently.
It is however also time to replace this type of setup with a newer and "cheaper to use" system like a FleetBroadband. Available as KVH or Sailor FB150, FB250 and FB500 to replace F33, F55 and F77.

What is the best marine satellite system


Intellian for ease of installation and leading edge technology. KVH seems built better, but the Korean Intellian i2 is really reliable and cheap! Plus it is a really easy install, especially for HD.

most likely is the coax from the dome to the receiver. Often this is intalled or terminated marginally and with age fails. Try crimping new ends on it.

Try the 'System' or 'P/N' key on remote to switch video modes.
These units also have poor power supplies. If your handy with
PCB repair check the capacitors. Be sure to replace any 10v caps with 16v (same uF rating) as they are probably for the 12v bus and 10v caps will soon fail.

The reading of the main thermistor does not reach 30°C 1 sec after the main
power switch is turned on. Or, it does not reach 70°C 2 sec thereafter.
Main cause The fixing film unit is faulty. The main thermistor has an open circuit. The
fixing heater has an open circuit. The main power supply PCB is faulty. The
DC controller PCB is faulty.
Caution To reset the error, execute the following in service mode:
COPIER>FUNCTION>CLEAR>ERR.
Action
1. Connector
Is the connector of the fixing assembly connected?
a. main power supply PCB (J8) <-> relay connector <-> heater
b. DC controller PCB (J320) <-> relay connector <-> thermistor
NO: Connect the connector.
2. Fixing film unit (thermistor)
Check the interval between pin 1 and pin 2 and between pin 3 and pin 4 of
the connectosr (4-pin) of the thermistor for electrical continuity. Is it ¥W
(open)?
YES: The heater has an open circuit, or the thermal switch is open. Replace the fixing film unit.
4. Main power supply PCB, DC controller PCB
Press the Start key. Is the drive voltage of the heater supplied by the connector J8 of the main power supply PCB?
Main heater: between J8-1 (FSR1) and J8-5 (FSR COM)
