EV-100 Deviation Change with R17

[Chuck - Raymarine - Moderator]

All,

The reported message was an engineering place holder message which has erroneously been left in place and will be corrected within the next Evolution autopilot software update.

It is recommended that you check current version of the EV-1 Sensor Core, ACU, and p70/p70R Autopilot Control Head to ensure that each has been updated with the latest software, as such performance issues may occur if one or more of these components was not successfully updated.

Please note that I have an EV-200 Power Pilot, a system of a/c/e/eS/gS-Series MFDs, and, an extensive SeaTalkng network onboard my own vessel ... and that I, as well as the overwhelming number of Evolution autopilot owners, have not experienced the deviation issue reported within this thread. As indicated within the software update web pages for the Evolution autopilot components and a/c/e/eS/gS-Series MFDs, it is necessary re-calibrate the autopilot following installation. As the Evolution autopilots are quite easy to configure, I personally recommend that a Factory Reset be commanded to the autopilot (via the control head), that the Dockside Wizard then be executed, followed by a cruise to establish the sensed deviation be performed. Should the maximum sensed deviation be more then 10 degrees, then it is recommended that the area around the EV-1 Sensor Core be inspected to ensure that:
- no ferrous materials (engine block, tools, tin cans, etc.) are located within 3' of the EV-1 Sensor Core
- no products featuring magnetic components (ex. electric motors, pumps, speakers, etc.) are located within 3' of the EV-1 Sensor Core
- no high current carrying conductors are located within 3' of the EV-1 Sensor Core

Should the EV-1 Sensor Core not be located within 3' of the above listed items and the EV-1 yield a maximum sensed deviation greater than 10 degrees, then it is recommended that the EV-1 be temporarily mounted above decks in a location well away from the items listed above. Should the sensed deviation fall below 10 degrees in the test location, then it is recommended that the EV-1 Sensor Core's prior installation location and the area at least 4' surrounding be inspected for items capable of producing magnetic fields and either relocate any such items or seek another location for the EV-1 Sensor Core. Should the sensed deviation remain high in the test location, then it is recommended that the EV-1 Sensor Core be bench tested/serviced by Raymarine’s Product Repair Center.
