34 Information LK200
8.4 Turntable
With turntables, the platform track is usually supplied with power. The tracks connected to the track
exits are only supplied with power if the platform points at them.
In digital operation, it is possible to leave on the light and the smoke generator while the
locomotives are out of service. This is particularly attractive in the area of motor power depots. To
this end, however, all tracks exiting the platform must be supplied with power.
When the turntable is turned by 180°, a short circuit will be created at the track exits. To avoid this,
the platform of the turntable is supplied by a LK200. Wire your motor power depot in the manner
illustrated in Figure 11.
The track exits shown in the Figure are available as accessory for the respective turntable. Isolate
on both sides at the rail joints to the track exit and supply the turntable with the LK200.
When a locomotive moves on the platform and is turned by 180°, a short circuit will be created in
the track connections when the locomotive moves off the platform, because the polarity of the
platform track and the track connection no longer match. The LK200 detects this short circuit and
the polarity of the platform track is reversed automatically.
