2.7. Malfunction
HADES detects faults possibly causing accidents in the staging yard:
failure of the track voltage (e.g. when a short circuit has occured on the layout)
remaining carriage (with current collector) in a sliding
failure of a track module
HADES stops the operation as soon as a fault is detected. Faults are displayed at LEDs on the
modules (→ section 5.2).
When a voltage failure occurs, all as-is states (occupancy signals, positions of turnouts) are
"frozen", in order to restart operation with the present settings as soon as the track voltage is
applied again. In case the malfunction is not caused by a voltage failure, a restart is required
after having eliminated the cause of the fault.
2.8. Power supply
Note:
HADES has to be supplied by a transformer
not
in use as an (analogue) driving transformer
or for supplying the digital system. If HADES is supplied by a transformer used as an
(analogue) driving transformer or for supplying the digital system as well, short circuits
possibly occur in the circuit leading to irreparable damages.
Note:
Analogue driving transformers with an extra connection for accessories ("lighing") beside the
connection for the track are
not
suitable for the common supply of rails and circuit. These
types of transformers are internally built of one transformer only!
Hint:
It is possible to supply HADES by a transformer in use to supply other accessories (e.g.
lightings).
