Thanks for the help and advice.

Problem solved. According to DCCconcepts there was a known issue with the Digitrax system and a software update was required to resolve it, this affected the DT602, DCS210 and now the DCS52. Updated the software this evening and all points now throwing and closing perfectly.

I attached the wires directly to the terminals marked Rail A and Rail B on the DCS52.

I have 5 Cobalts numbered 0001 to 0005 using the Dynamis and all work fine using those addresses on the Dynamis. I have even changed the addresses using the DCS52 and still get the same brief groan when using 'throw' and 'close. If I plug them back into the Dynamis they work fine. 

So I setup all my Cobalt IP Digital point motors using a Bachman Dynamis, all working fine and throwing from left to right using the Dyanmis.
I then took the plunge and treated myself to a Digitrax DCS52, attached it to the layout and turned the power on, selected the address of one of the Cobalts and pressed throw, all I got was a very brief groan from the Cobalt and then nothing, selected another Cobalt and pressed throw, again a brief groan and nothing, what have I done wrong?
