Loops in Digital Operation

Note: To make sure that the loop
module responds quickly enough,
the sensitivity must be set prior
to operation using the potentio-
meter visible at the side. Observe
operating instructions.

4. Loops in Digital Operation
Every DC railway enthusiast knows the following problem: if after a loop, the left rail profile meets the
right one, a shortcircuit occurs without the appropriate wiring.
With our loop modules (Art. No. 10767), this switching problem in digital operation is elegantly taken
care of: simply separate the loop on both sides on two poles and insulate the rest using insulated
connectors (Art. No. 42611, 61192, 6433 or 9403) electrically from the remainder of the layout (see
Page 47). The separated layout portion within the loop must be longer than the longest train which is
to drive through the loop. The power to the loop is supplied by the loop module which is connected
either to the track outside the loop or to the
And this is how the loop module works: as soon as a train enters the loop regardless of the direction,
shortcircuit detection occurs in the module. The polarity in the loop is automatically changed before
the shortcircuit detection of the Digital Centre is aware of it or before the trains slows down. The
polarity reversal is repeated when the train leaves the loop. Thus, the train can pass through a loop
without stopping or operator intervention.
