The manual controller that comes with the turntable provides the plug interface to the turntable and a rather pathetic direction knob and on / off button to stop and start the turntable

I used the bridge rectified out of the manual controller, open up the case...

and simply desolder the 4 legs of the rectifier.

I positioned a Viessmann 5213, the rectifier and the turntable plug on a wooden base

and wired it up as can bee seen in the picture. 2 of the 4 switches are used to reverse the polarity of the DC current produced by the rectifier. A third switch is used to switch the stop/go signal for the turntable to be the same as one of the motor polarities. One rail plug of the turntable plug is left free for a s88 port to detect occupation or it can be grounded also. All the new module needs is one ground, one digital and one power supply to be connected. I suggestthat you run the yellow power supply through a manual override switch. You can also connect an optional s88 line.

plug it all in, add some lines of code to the program and it all works !
