1. Getting started
The instructions will help you step by step with the safe and proper installation and use of
your staging yard control. Before you put the module(s) into operation, read this manual
completely, especially the safety instructions and the section on possible errors and their
elimination. You will then know what you have to pay attention to and thus avoid errors that
sometimes can only be rectified with a lot of effort.
Keep the instructions in a safe place so that you can restore functionality later in the event of
any malfunctions. If you pass the module(s) on to another person, also give the instructions
with it.

1.2. Accessories
Connection cables
The use of stranded wire is recommended for the connections. Stranded wires consist of
several thin individual wires and are therefore more flexible than rigid wires with the same
copper cross-section.
Connection to Recommended cross-section
Power supply, tracks and turnouts > 0.25 mm²
Push-buttons, switches, LEDs > 0.04 mm²
External push-buttons and indicator LEDs (optional)
You can manually trigger the exit of the trains from the tracks via additional external push-
buttons and/or have the occupancy status of the tracks displayed on additional, external
LEDs. You then need per siding:
one push-button 1 x make contact (e.g. item no. 84-5211x or 84-5212x )
one red and one green LED and one series resistor per LED (> 120 Ohm)
Set up a stopping section at the entrance to the staging yard (optional)
For this you need
a bistable relay 12 V (e.g. item no. 84- 1111). Note: If you want to control a semaphore
signal together with the stop section, a bistable relay 1xUm is sufficient, for simultaneous
control of a light signal you need a bistable relay 2xUm.
or a relay circuit board RL-2 (kit item no. 72-00055-01 or ready-made module item no. 72-
0005 -01)
and, if necessary, a entry signal without train control.
As an alternative to using a relay, you can directly connect an entry signal with train control.
Using motor-driven turnouts or turnouts with servo drive (optional)
If you do not use turnouts with double coil drives as entry turnouts, you will need additional
circuits that enable the turnouts to be switched by means of switching pulses:
for motor-driven turnouts: adapter AMW-1 (item no. 72-0007 -01) or AMW plus (item no.
72-0017 -01)
for turnouts with servo drive: SD-32 servo decoder for analogue or digital control (ready-
made module item no. 43-0032 -01 or ready-made device item no. 43-00327-01)

1.3. Intended use
The staging yard control HADES is intended for use in digital model railway layouts as
specified in the instructions. Any other use is not in accordance with the intended use and will
result in the loss of the warranty claim. Intended use also includes reading, understanding and
following all parts of the instructions. The staging yard control HADES is not intended to be
used by children under the age of 14.
1.4. Safety instructions
Note:
The modules contain integrated circuits (ICs). These are sensitive to electrostatic charging.
Therefore, do not touch these components until you have "discharged" yourself. For this
purpose, e.g. a grip on a radiator is sufficient.
Improper use and non-observance of the instructions can lead to incalculable hazards. Prevent
these dangers by carrying out the following measures:
Only use the staging yard control in closed, clean and dry rooms. Avoid moisture and splash
water in the environment. After condensation has formed, wait two hours for
acclimatisation before use.
Disconnect the modules from the power supply before carrying out wiring work.
Supply the unit only with extra-low voltage as specified in the technical data. Use only
tested and approved transformers.
Only plug the mains plugs of transformers into properly installed and fused earthed sockets.
When making electrical connections, ensure that the cable cross-section is sufficient.
Heating of the modules during operation is normal and harmless.
Do not expose the modules to high ambient temperatures or direct sunlight. Observe the
information on the maximum operating temperature in the technical data.
Regularly check the operational safety of the modules, e.g. for damage to the connection
cables.
If you notice damage or if malfunctions occur, disconnect the connection to the power
supply immediately. Send the module(s) in for inspection.
1.5. Care
Do not use any cleaning agents to clean the modules. Only wipe the modules dry. Disconnect
the modules from the power supply before cleaning.

2. Your staging yard control HADES
HADES supervises and controls the activities in a staging yard with
2 to 32 sidings
and one transit track or a stopping section at the entrance to the staging yard.
2.1. Possible applications
HADES works independently from the rest of the layout control system and can therefore be
used in analogue DC or AC layouts as well as in all digital layouts.
In principle, HADES is suitable for all nominal sizes. The maximum switching current of the
relays that switch the track voltage for the sidings is 3 A. Therefore, the maximum current of
a train in a siding must not exceed 3 A.
HADES has a connection for an external on/off switch that switches to ground. As long as this
switch is closed, it is impossible to trigger a train exit from one of the sidings. This makes it
possible, for example, to integrate the staging yard controlled by HADES into a block station
control.
2.2. Components
HADES has a modular structure and consists of
a basic module for monitoring and controlling 2 sidings as well as a transit track or a
stopping section at the entrance to the staging yard,
additionally up to 15 track modules for two further sidings each. The last track module can
be configured to monitor and control only one siding.
Basic and track modules are connected to each other via patch cables.

2.3. Concept of a staging yard with HADES
Number of sidings
The number of sidings in the staging yard is at least 2 and at most 32. An uneven number of
sidings in the staging yard is possible. For this purpose, a jumper is attached to the last track
module and this track module is thus configured for the monitoring of a single siding track.
Security
In order to prevent accidents caused by further arriving trains when all sidings in the staging
yard are occupied, you can either
install a transit track allowing incoming trains to drive through directly or
install a stopping section at the entrance to the staging yard, where trains wait until a
siding has been cleared. The entry signal for the staging yard can be controlled commonly
with the stopping section.
Example 1:
Staging yard with 6 sidings and one transit track
Example 2:
Staging yard with 6 sidings and a stopping section at the entrance
Your staging yard control HADES | 9

tams elektronik
HADES tams elektronik
Track sections
The sidings have to be separated electrically from the rest of the layout. HADES works
comparably to switches to switch on and off the track voltage for the sidings. As long as a
siding has not been switched off by HADES, the train reacts to switching and driving
commands of the (analoque or digital) layout control unit.
All sidings have to be divided into two sections (A and B). The sections must have the
following minimum lengths:
Section A: at least as long as the longest locomotive or driving trailer
section B: at least as long as the longest train including locomotive
As it is not possible to direct an incoming train to a specific siding, all sidings must have these
minimum lengths.
Entry and exit turnouts
HADES sets the turnouts at the access to the sidings according to the operating principle of
push-buttons. Turnouts with double coil drive can be directly connected as entry turnouts. In
order to control motor-run or servo-driven turnouts you need additional control devices (see
chapter 1 "Accessories").
The exit turnouts are forced open when a train is departing from the staging yard. For that
reason you have to use turnouts not blocking to be forced open.
2.4. Modes of operation
The following operating modes can be selected with the help of buttons located on the basic
module:
First-in-first-out: An incoming train releases the departure of the train which is in the
staging yard for the longest time. Consequently, the order of the arriving trains is
maintained.
Random control: An incoming train releases the departure of an arbritrary train.
Manual control: Pressing a push-button releases the departure of the train on the assigned
siding.
Even if one of the two automatic operating modes "First-in-First-out" or "Random control" is
set, it is always possible to manually trigger the exit of a train from a specific track.
The operating mode set in each case is saved and set again the next time the system is
switched on.

2.5. Procedure
After switching on or after a restart, HADES first checks
the number of connected track modules;
whether the last track module monitors and controls one or two sidings;
whether sidings are occupied or free.
If vehicles have been manually removed from a siding or parked there in the switched-off
state, HADES sets the entry turnouts according to the current occupancy status.
Phase 1
The entry turnouts of all free sidings are switched to "branch" (into the siding). An arriving
train therefore enters the first free siding (seen in the direction of travel). For all free sidings,
section A is de-energised, section B is energised.
Phase 2
As soon as the integrated track occupancy detector detects a power consumer (locomotive,
illuminated wagon) in section A, section B of the siding is also de-energised. The train stops,
all consumers (e.g. lighting) are switched off. When the train enters the siding, it does not
matter whether the locomotive pulls or pushes the train. The only thing that is essential for
the control to function is that there is a power consumer (e.g. a light) at the end that enters
section A. The power is switched off at the same time as the train enters the siding.
At the same time as the power is switched off in the siding, the entry turnout is set to
"through". Subsequent trains can then no longer enter this track.

HADES tams elektronik
Phase 3
The departure of a train from a siding is released, as soon as
another train is arriving in the staging yard (with automatic operation modes "random
control" or "first-in-first-out" set)
or the push-button assigned to the siding is pressed (in all operation modes).
Then the current is switched on in both track sections (A and B). When departing from the
staging yard, the train cuts open the turnout.
The departure of a train is blocked, when
the switching contact of an external on/off switch is closed,
a train has just departed from another track (and the set departure time* has not yet run
out),
HADES has interrupted the operation due to malfuncion.
Phase 4
After the integrated track occupancy detector no longer detects a consumer in the track after
the departure time* has expired, section A is de-energised again and the entry turnout is set
to "branch" (into the siding).
In case a (control) carriage with own current collector tears off during departure, the
occupancy message remains after the departure time* has run out. HADES detects the fault
and freezes the operation in the staging yard.
Hint: in 2-rail systems carriages without current collector are detected, if the axles are painted
with resistive varnish or a resistor (approx. 10 kOhm) is soldered between the two wheels that
pick up current.
*Departure time
The departure time is set in common for all tracks. It defines the period of time that elapses
after releasing the departure of a train from a siding, before
the departure of the next train is possible,
HADES defines a track occupancy signal from the track in question as a "fault" (due to a
current consuming carriage probably having been torn off),
the entry turnout is set to "branch" into the siding.
the current for track section A is switched off.
The departure time can be set to a time between 2 and 20 seconds (in 1 second steps). In
state of delivery the departure time is set to 5 seconds. You can always alter the setting
during ongoing operation.

2. . Operation elements and displays
Selecting the operation mode
You select one of the operating modes
manual control,
random control or
first-in-first-out
with the push-buttons on the basic module. A LED shows which operation mode has been set.
Manual triggering of train departure
On each (base or track) module there are two buttons with which the departure of a train
from the two associated sidings can be triggered manually. Red and green LEDs indicate
whether the two tracks are occupied or free.
In addition to the exit push-buttons and busy occupancy LEDs on the modules, external
buttons and LEDs can be connected. These buttons and LEDs can be built into a track diagram
control panel, for example.

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).

3. Setting-up the staging yard
3.1. Sidings
Number of sidings
The number of sidings in the staging yard is 2 to 32. The basic module and the track modules
can monitor and control 2 sidings each. If you need an odd number of sidings, you can
configure the last track module to monitor and control only one track section.
Minimum lengths
All sidings must have the follwing minimum length:
length of the longest locomotive or the longest (control) car (section A)
+ length of the longest train (section B)
Electrical separation of the sidings
The sidings must be electrically separated at the following points:
directly behind the entry turnout (seen in direction of travel)
directly before the exit turnout (seen in the direction of travel)
between sections A and B of the siding
To do this, disconnect
the centre conductor in the case of 3-conductor systems or
the left rail as seen in the direction of travel in the case of 2-conductor systems.

3.2. Turnouts
You can use the following as entry turnouts:
coil-driven turnouts: without any additional components
motor-run turnouts: in combination with adapter AMW-1 or AMW plus
servo-driven turnouts: in combination with additional modules controlling servos (e.g. servo
decoder SD-32).
The exit turnouts must allow to be cut open by departing trains.
3.3. Transit track or stopping section
In order to prevent accidents when all sidings are fully occupied, you have to choose one of
two safety measures:
Transit track: An incoming train first has to pass all entry turnouts leading to the sidings
before it directly departs from the staging yard when all sidings are occupied.
Stopping section at the entrance to the staging yard: The section is switched currentless
when all sidings are occupied. If you want to install a stop signal in front of the stopping
section, you can switch it together with the stop section.
Examples → Section 2.3
