Power Station LV200 9
DIGITAL plus
The additional LV200s receive the control signals from the
terminals C and D of the first LV200. Each LV200 has to be
connected to its own transformer. The number of power station-
transformer-units needed depends on the overall power
consumption of your model railway.
It is absolutely necessary that the electric circuits of all the
LV200's are the same polarity. Thus, terminal J of one and
terminal J of the next LV200 must be connected to same side of
the track in question. Otherwise short-circuits will occur when
operating a locomotive over gaps that divide the power districts.
Advice on the wiring of the model railway
Use only cables with a minimum cross section of 16 AGW when
connecting the tracks and twist these cables. Moreover, the power
station should always be placed as close as possible to the first
point of power supply.
For extended routes you need additional track power connections
at regular intervals. Rule of thumb: every 3m.
No capacitor for interference suppression may be installed into the
track system. Such a capacitor is necessary for the interference
suppression only in conventional operation. When used with the
Digital plus by Lenz ® system it would, however, distort the data
format and interfere with the fault-free transmission of data.
Common Rail Wiring
Normally both rails are gapped between power stations. This
provides complete isolation. However, in some scales there exist
locomotives that have pickups that are offset from each other. For
example many steam locomotives have power pickup from one rail
in the locomotive and the other rail in the tender. When such a
locomotive bridges the gap between isolated power stations, the
locomotive will stall. The solution to this problem is to provide a
common wire between all power stations. All systems of
command control need to have a such a common provided, if
offset pickup locomotives are to be operated.
Lenz has chosen to leave the option of the location of the common
up to the individual operator. The LV200 is completely opto-
isolated. This allows you to use one of the rails (called common
rail) for your common. Common rail wiring is also compatible with
