Feedback of a wrong position of turnouts (WD-34.2 only)
After the set switching time ("on-time"), the turnout decoder WD-34.2
compares the actual position of turnouts with limit stop with the
position it should have according to the digital commands. If the
position does not match, e.g. because
a mechanical problem has occurred or
the turnout has been switched manually
the fault can be displayed at an external LED (LED not included in the
package). The flashing sequence shows the turnout in question.
Short-circuit protection
In case a short-circuit occurs while switching a connected accessory,
the decoder stops the switching operation and the LED on the PCB
starts to flash quickly.
Power supply
The turnout decoders can either be supplied by the central unit or a
booster. In order to release the digital electric circuit it is also possible
to supply the decoders by a transformer of their own instead.
