Troubleshooting Guide Maritime Antenna Systems

• Check antenna to control unit cable
• Check antenna unit's power supply (12V ..36V)
  
• Test rotary joint for fault.

• Check the error message seen before ("lowVsup" or "No dish")
  
• Recheck antenna's power supply

• Turn unit off and after 3 seconds on again

• Check if power supply connection to antenna unit is too low (<11.5V) (loose cable..) or any voltage drop
  
• Check if voltage supply is continuous or it drops/varies sometimes
• Check for high resistance/load
• Check voltage on slip ring
• If there is sufficient voltage & low load, then the E-Box is faulty

Turn the unit off and on again. In case the error reoccurs, call for technical assistance.

In case of errors regarding limit switches:
Check all moving parts for non-blocking functionality.

Err ULS / Err LLS:

• Check lose cable connection
• fault in sensor, plug or cable -> exchange sensor / cable
• Magnet is missing or screw is not correctly positioned -> check using limit switch tester

• Repeat search and store. Make sure the boat is not moving and has no blockage
• Try to save the satellite in different scan-bands
• If issue persists, after multiple retries, then replace E-Box

• Check the connection between E-Box and Skew-Box

• GPS signal is jammed by another signal source
• GPS receiver is defective

• Check RX cable connection to antenna and rotary joint inside the antenna

(VSAT systems)

• Check if something obstructs the sight to the satellite
• Reception can be interrupted by passing boats

• Check for line-of-sight issues
  
• Check, by using footprint cards (e.g. www.satbeams.com), whether the boat is inside the coverage area (footprint)
• Check antenna to control unit cable
• Check power to LNB
• Verify tracking frequencies

• Update the stored satellite or delete and make new setup

• Check for line-of-sight issues

• Read the current frequencies via progsoft and verify if a valid frequency is present for the current scnband. If not, try to make a new setup with another scnband.
  
• Verify latest frequencies via lyngsat and reprogram antenna
