A GW data path error on your Simrad Marine Radar indicates an FPGA error. To resolve this, perform a system restart.

How to resolve GW data path error on Simrad HALO 5000 Marine Radar?
A GW data path error on your Simrad Marine Radar indicates an FPGA error. To resolve this, perform a system restart.
Why is there transceiver performance loss in my Simrad HALO 5000 Marine Radar?
The performance monitor may indicate a degradation of at least 10dB on TX and/or RX in good weather conditions. If it is a false alarm, and you have a good radar image, clean the antennas and check the cabling between the performance monitor module and antenna. If the alarm is valid, and you have no or poor visibility, check for traces of water inside the pedestal.
What to do if Simrad HALO 5000 shows motor drive fault?
If your Simrad Marine Radar shows a motor drive fault, begin by restarting the pedestal. If the alarm persists, switch off the system and try to rotate the antenna by hand.
What causes PSU overheat in Simrad Marine Radar?
PSU overheat in your Simrad Marine Radar is caused by the power supply's temperature being too high. To resolve this, restart the pedestal, wait 5 minutes, and then let the pedestal operate for at least 1 hour.
How to fix motor driver error in Simrad HALO 5000 Marine Radar?
To address a motor driver error in your Simrad Marine Radar, first, restart the pedestal. If the issue continues, replace the motor and gear.
What causes PA soft over heat in Simrad HALO 5000 Marine Radar?
PA soft overheat in Simrad Marine Radar occurs when the power amplifier temperature is too high. To resolve this, restart the pedestal, wait 5 minutes, and let the pedestal work for at least 1 hour.
What happens when persistence is corrupt on Simrad HALO 5000?
When persistence is corrupt on your Simrad Marine Radar, the radar will revert to default settings. Re-enter your settings, including installation settings.
Why is my Simrad HALO 5000 in safety mode?
Your Simrad Marine Radar is in safety mode because the safety switch is in position “0”. Change it to position “1” (pedestal active).
What does PSU hardware fault mean on Simrad Marine Radar?
A PSU hardware fault on your Simrad Marine Radar indicates that the power supply is in fault. To attempt to resolve this, restart the pedestal and try again.
What to do if Simrad HALO 5000 Marine Radar shows PSU power issue?
If your Simrad Marine Radar indicates a PSU power issue, it means the power supply's power is too high. To resolve this, restart the pedestal and try again.
