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
• 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.
• 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
• 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.
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
