Appendix A: Maintenance and Troubleshooting

SkyView System Installation Guide - Revision R 20-9

 Check network wiring and try again. There may be a short or an open somewhere.

 Unplug network modules one by one and try again. It is possible that one of the modules

could cause the network to stop functioning.

 Try again.

 For modules such as the SV-ADAHRS-200/201, the SV-EMS-220/221, and SV-ARINC-429,

observe the red LED light near the SkyView Network connector:

o Flashing Fast: The module is operating normally and is configured and

communicating on a SkyView Network.

o Flashing Slowly: The module is operating normally, but is not active on SkyView

Network.

o Off: The module is not receiving power (from a SkyView Network / Display)

o On Solid - the module is receiving power, but is not operating normally.

SkyView Reports STANDBY NETWORK ERROR

SkyView has detected a problem with the SkyView Network wiring between one or more

modules. Go to SETUP MENU > SYSTEM SETUP > NETWORK SETUP > NETWORK STATUS for a

description of the problem. Module failures and/or wiring faults (via SkyView D9 connector pin

callouts) will be annunciated here to aid troubleshooting. The fault will be below the

component(s) that SkyView can see the fault in. This may help you narrow down the wiring run

or connector that is faulty.

For example, a “Connection Fault: 4/8” listed below an SV-ADAHRS-200 listing in the network

status page means that pins 4 and 8 on a SkyView Network harness or connector that goes to

that component has a connectivity problem. This could be a broken wire, swapped wires, bad

connection, etc., and should be analyzed with a multimeter or other direct method.

If the fault were instead listed under a SkyView display listing in the network status page, that

means that the fault is seen on devices connected to that display, and is likely due to a

connectivity issue at or very near the display in your SkyView Network wiring scheme.

Compass Calibration Fails

If you try to calibrate your compass and it does not work, try the following:

 Ensure SkyView is receiving data from the system’s GPS receiver – a

message: VALID GPS SIGNAL REQUIRED TO CALIBRATE COMPASS will appear if GPS data is

not available.

 Ensure the SkyView network status includes the ADAHRS you’re trying to calibrate. Use the

Network Status Wizard and confirm that the ADAHRS is present in the system.

 Ensure the ADAHRS location is compatible with the requirements outlined in the General

System Installation Tips Section of this guide, especially the discussion of external magnetic

interference.

Display does not Turn On

If your SkyView display does not turn on, try the following:

1 2 ... 344 345 346 347 348 349 350 351 352 353 354 ... 400 401
