52 Information SET-02
If you wish to traverse the reverse loop with a locomotive without a
decoder (analog locomotive), proceed as follows:
•
drive the entire train into the reverse loop (the train must be
between contacts a2 and b2)
•
stop the train and change direction with your handheld (LH100).
•
now manually change the polarity in the reverse loop (for
example by using push buttons connected in parallel with track
contacts a2 and b2)
•
continue driving the train through the reverse loop.
You must use this sequence with analog locomotives (non-decoder
equipped), since their direction of travel is dependent on track
polarity.
15.5.2 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 the 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
many existing signalling systems. While common rail is the
preferred place for a common, you may rather connect all the power
station
U or V wires together. This is called common power supply
wiring.
Caution: If you decide to install a common, it is important that you
only have a single common. Multiple commons (such as common
rail and common transformer) should be avoided.
15.6 Mixed operation: conventional DC and digital DCC
Conventional and digital electric circuits must always be thoroughly
separated from each other, for example, by installing contact-
breaker gaps or insulating rail joiners between digital and analog DC
blocks.
