I have tried as below with no success

The unit will need to be reprogrammed as a stand alone unit before it can be run on its own. The overload is an error state.

Thank you for your answer Alexandra, Can I reprogram it to stand alone by the dip switches, I have tried setting them as dia in my first post third across, with no success, Is their some where I can get instructions to do this by the dip switches. or do I require the computer link.

You can do so through the dip switches. Their manual has all the information in them.

Manuals are available for download on their product page if you do not have the physical copy.

The computer link makes it easier if you know how to program them using it. Usually it is easier to upgrade the firmware and that wipes all past setting on the unit.
