Operation - tams elektronik PZS-3 Manual

English
In case you do not use stop-points you should connect an extra
bistabile relais 12 V (or a relay circuit board RL-2) to the points. The
bistable relais switches on the power supply for the one rail in terminus
station 2 while switching off the power supply for the other rail. If
neither stop-points nor a bistabile relais are connected both rails are
constantly supplied with power.
Emergency stop at a terminus station
If the locomotive does not accept the impulse for changing the direction
at the terminus station, it goes on into the wrong direction. To prevent
accidents it is recommended to interrupt the middle conductor at the
point the train should not cross.

9. Operation

Caution:
!
The maximum current of a train in the shuttle-train section should not
exceed 1 000 mA (including all loads as e.g. carriage lightings). When
exceeding the maximum current, components on the circuit can be
damaged.
First operation and starting of new locomotives
On principle it is not possible for the shuttle-train control to set absolute
directions of motion ("way there" / "way back") for the locomotives.
When a train reaches a terminus station the module sends the impulse
for changing the actually set direction. Therefore you should keep to
the following when first starting the shuttle-train control or new
locomotives:
The train must start at a stop (not at a terminus station) or on a free
section. Depending on the position of the switching relay it goes into
the direction "there" or "back". If the train is standing at a terminus
station when first starting, it cannot be ruled out that it runs in the
wrong direction against the buffer.
