[DG11] Compatibility with older transucers and displays

RE: [DG11] Compatibility with older transucers and displays
Hi Russell,

Thank you for your enquiry,

It sounds like you have retained the original drive unit and updated the electronics? If this is correct, then it is possible the clutch is sticking in the drive unit.

Completely disconnect the clutch connection from the ACU200, then energise the clutch by temporarily connecting the two clutch wires from the drive to 12v - the drive always uses a 12v clutch supply, even on 24v boats.

If the clutch remains engaged when the 12v power is removed, then I would suspect a mechanical issue inside the drive unit, either there is some fault in the mechanism which allows the clutch coil to slide to and fro. or more likely there is some foreign substance on the clutch faces, which is literally causing them to stick together.

If the clutch operates fine, then check the ACU 200 is not still outputting 12v on the clutch output - it would be very unlikely for the ACU200 to be faulty in this way, but also worth checking.

The ST290 should be connected to STng by connecting the SeaTalk 1 part of the ST290 to a SeaTalk to STng converter and connecting the STng part of the converter to the STng network that connects the new EV pilot and e7D. The SeaTalk2 part of ST290 is very different to the current STng and so we do not recommend connecting SeaTalk2 from ST290 to STng.

regards

Derek
