Track Condition „Free/Occupied" In Automatic Operation; Feedback Addresses - FLEISCHMANN TRAIN-NAVIGATION6893 Handbuch

8.4.5 Track Condition „free/occupied" in Automatic Operation
If a vehicle with a navigation transmitter runs over a navigation receiver set to automatic
operation, then the programmed tasks are carried out as previously described. Internally, the
navigation receiver will itself note that it is now „occupied". This means that the navigation
receiver will now wait until it is „free" again, to wait for the next vehicle. As long as the
navigation receiver is „occupied", then it cannot handle any other vehicle in automatic
operation.
If a vehicle has entered a block automatically, but exited by a manual operation, the block
must be set back to „free" again before the next vehicle can enter. This „free" setting can be
carried out by setting the block signal first of all to „green" and then to „red" again.
Whilst in automatic operation, the occupied message is always generated when running over
the sensors, the free message can be altered by programming LNCV10:
LNCV Name
10 Block free
It is recommended that in the function as shuttle stretch or station stop, to give a time delay
using a time function to the station which has just been left to set „free" and also to set the
signal to „red" again.

8.4.6 Feedback Addresses

In chapter 8.2.4 we have already learned how a navigation receiver can be made to switch
individual electrical accessories (points, signals) and complete routes of points from the
TWIN-CENTER, but in addition, also feedback addresses can be notified as „free" or „occu-
pied".
These conditions of the feedback addresses can be shown visually in the display on the
TWIN-CENTER in the s88-mode, or they can also be questioned by a computer and worked
on from there. Commands to switch electrical accessories and routes as well as feedback
have the same value, meaning that in each LNCV, in which a command to switch an acces-
sory or route can be entered, a command for feedback can also be entered. Also the route
addresses to enter, or exit, stations can in principle, be replaced by feedback addresses,
provided that another piece of equipment (computer or for example an ib-switch (made by
Uhlenbrock)) will react to the feedback addresses and switch a corresponding route.
Value Description
Options for the alteration of condition from
„occupied" to „free"
0 The block condition will be altered from „occupied"
to „free", if a train in automatic operation departs or
runs through and finally sets the exit signal (LNCV6)
to „red"
1-255 The block condition will be altered from „occupied"
to „free", if a train in automatic operation departs or
runs through and subsequently the set „value"
number of seconds have gone by
257-511 If the figure 256 is added to the values from
1 to 255 , then the same number of seconds will
pass by until it is „free", but after the waiting time,
the signal will be set back to red again.
