[DG] [DG11] Autohelm 3000 - control box beeping constantly

Dear peter@dideriksen.info

Thank you for your enquiry,

From your description is sound slike you are referring to the early Micro 3000 control unit? This was rectangular in shape, about 6" x 4" x 2" and was secured onto a bulkhead through a dovetail bracket.

If this is the case, then the 2000 or the 4000 control boxes of the same era, would not control the 3000 drive, since they used different control algorithms, they might work after a fashion, but unlikely to be acceptable.

The circuit diagrams remain proprietary and we do not disclose them.

We would suggest to update the electronics and retain the drive unit.

The current ACU100 electronics could be used with this drive.
Regards

Derek
