[DG] [DG11] Autopilot/system cabling questions

Hi Kmac,

Thanks for the feedback, not sure what happened to the earlier response but here it is again!

There are a couple of simple checks to carry out before leaving the dock.

With the p70 in STANDBY mode, turn the wheel to starboard and check the rudder angle display on the p70 goes the correct way - turn the wheel to Starboard, the rudder angle display should show a green bar proportionate to the amount the wheel is turned. Turn the wheel to port and the display should indicate a red bar proportionate to the amount the wheel is turned. if the rudder bar indicates the opposite direction, then the red and green wires of the rudder reference unit need to be swapped where they connect to the ACU.

The second test is to select AUTO on the p70, then select 2 x +10, the wheel should turn to starboard and the display show starboard rudder, repeat the test selecting 2 x -10 to turn the wheel to port. If the wheel turns the opposite direction, then the MOTOR wires must be reversed where they connect to the course ACU.

The issue you describe with track mode, this can be resolved by entering the current local Variation value into the calibration of the p70 as a manual variation setting, this should then enable the track mode to be accessed.

The E120 should be outputting Track data to the pilot, but the EVpilot needs variation to operate in track mode and the E120 is of an age where this data is not passed through, hence the need to use manual variation in the p70.

The schematic you attached should be fine, although personally I would have recommended disconnecting the SeaTalk2 from the E120 and connecting SeaTalk 1 from the E120 to the current ST60+ instruments, this would be a more reliable configuration.
