常见问题

  • No Radar

    This means the MFD cannot communicate

    with the radar in any way. There a very

    broad range of possible causes including:

    - Radar Ethernet Hardware fault

    - Radar SW Software bug

    - Ethernet cabling fault

    - No power to the radar

    - Ethernet hardware fault in MFD

    - MFD software bug 


    Recommendations:

    • Check / select actual radar in radar sources

    • Turn the system off and on again

    • The most common error: The safety switch is

    switched off - only HALO radar

    • No voltage on the yellow power supply line

    • No voltage on the yellow lead of the radar cable

    from the radar interface

    • Missing or intermittent Ethernet connection, the

    RJ45 connector is damaged

    • Broken Ethernet cable


  • Acoustic Noise Detection of the sonar

    • Stop the vessel, and stop the propeller.

    – If the noise disappeared, the noise is either coming from the water flow, the propeller, the reduction gear or the propeller shaft (most likely water flow or propeller)

    – Try different propeller pitch

    • Give full speed ahead

    – The noise comes up gradually

    with speed, then you have flow- noise (Transducer installation)

    – The noise comes up immediately!

    You are faced with propeller noise.


  • Dockside Faults – No Drive Output

    • Make sure the motor wires are attached to the correct terminals

    • Check the output commands and the voltage levels at the motor drive terminals

    – Simply make meter contact with the AC drive terminals and issue a command

    – Issue a command in the opposite direction; you should see polarity reverse on your meter

    – NOTE: You can issue commands directly at the AC by temporarily shorting the Remote terminal PORT or STARBOARD to ground

    • When driving solenoids, the drive voltage can be measured from the ground common (SOL GND) to one of the SOL-MOTOR terminals when a rudder command is issued. Remember when driving solenoids your mains supply is what you will provide to the solenoid terminals and bypass

    – Insure your are correctly connected and 12V is present on the SOL-MOTOR contacts when the autopilot issues a command


  • Dockside Faults – No Pilot Computer

    • If all fusing and power is correct, you can isolate between the AP and the AC by making some quick assumptions

    • Do I see a compass heading and a heading source shown on the AP controller? Yes Pilot Display OK

    • Are my sources properly configured in SimNet and can I see the Pilot computer in the device list?  If seen by the network it will be listed next to the Distance Log and Pilot sources.

    • If you still do not ‘see’ the AC unit your best recourse is to enter the Service Menus of the AP and perform a Global Reset, then cycle the power.


  • No Spoke data for radar

    As a persistent error

    This means the MFD is still communicating with the radar, but it is not receiving radar image data over Ethernet.

    This is likely to be a radar hardware problem (typically FPGA) or in rare cases a radar software problem.

    This error can NOT be caused by cabling faults.

    Recommendations:

    • Turn the system off and on again

    • FMWC and PuC radars usually need to be

    replaced as this is an internal failure

    • Pulse Radar: Check / replace the HD scanner unit
