Connection for the external control
The start/stop function can be triggered by any number of rail contacts to the control
terminals 1 and 2 by the moving train. To do this the rail contacts must be decoupled by
rail contacts. You will
fi
nd a y-point that is pre-prepared for the bed track under product
no 83758 in the programme. There is a corresponding y-point under article number 83158
for the model track. A circuit board with 2 diodes is also available for other track systems
under product no. 08401. The control terminals 1 and 2 may not be connected with one
another!
Several rail contacts can be connected to the control terminals 1 and 2 of the TFi2 to re-
peat the action of the automatic stopping and starting up again after a time delay at as
many points as you please. For every drive direction the rail contacts at which the stopping
actions are triggered must be integrated in the respective right-hand rail that is provided
with a positive polarity. It is thus possible that as many stopping points as you like can be
arranged on the track which only act in one drive direction in accordance with the arran-
gement of the rail contact. The connection of the rail contacts in both directions can also
be performed at a control terminal if the second terminal for the two limit stop contacts
of a commuting route. The action of the control terminals is determined by the selected
option.
In this way a commuting train automatic system can be set up with the TFi2, which can in
conjunction with the use of the
fi
rst terminal also give rise to a different number of stops
for both drive directions. When determining the location of the rail contacts before the
stopping point of the vehicles the delay time must be observed which is still covered by the
traction vehicles whilst still travelling after the triggering of the contact.
Due to the fact that you also have the option of directly controlling railway switch drives
with rail contacts it is possible that the train uses siding places in both directions also via
different sorting sidings between the terminals. These y-points that are necessary to con-
trol the points must be additionally inserted into the railway track – i. e. separately of those
y-points which serve to control the TFi2.
However – as is always the case during analogue operation – only one traction vehicle can
ever be controlled at one time with the TFi2. Other traction vehicles must be taken off
without current.
The TFi2 thus possesses an integrated, shuttle train and stopping automatic mechanism
that is remotely controlled by rail contacts.
