Track Circuit selection

Track circuit selection varies according to the 
control device being used.  In the following 
section each device is briefly described.  For 
more detailed description refer to the manual for 
that device. 

Track Circuit selection with DAISY 

A DAISY handcontroller connected to the 
LocoNet socket of a Power 2 automatically 
recognises analogue operation and displays the 
letter “A” as the data format.  With factory setting 
it will control track circuit 1.  The [lok] key can be 
used to select another track circuit. 

Track Circuit selection with FRED 

Firstly FRED must be configured as for operating 
with a TwinCenter.  Using the function keys you 
can change FRED’s LocoNet ID.  The meaning of 
the ID selection is: 
ID 1 – track circuits 1 to 4 (factory setting) etc. to 
ID 16 – track circuits 61 to 64 
After this is set up one of the 4 track circuits can 
be selected by pressing the [lok] key followed by 
one of the function keys [f1] to [f4]. 

Track Circuit selection with IB-Control 

No setting up is required.  The track circuits are 
selected as in selecting a locomotive decoder. 

 

Press [lok]-key 

 

Enter the address of the track circuit using the 
numeric keys 

 

Press the [ 

 

 ]-key for it to take effect 

Track Circuit selection with Profi-Control 

8 track circuits can be controlled with each Profi-
Control.  Which 8 is determined by the LocoNet 
ID: 
ID 1 – track circuits 1 to 8 (factory setting) etc. to 
ID 8 – track circuits 57 to 64 
After this is set up one of the 8 track circuits can 
be selected by pressing the [stop] key followed by 
one of the function keys [f1] to [f8]. 

Coupling two track circuits 

With a DAISY system it is possible to momentarily 
couple the track circuit where the locomotive is 
with the next track circuit.  All the locomotive’s 
parameters, such as speed, direction and state of 
the special functions can then be transferred 
between the sections.  As soon as the locomotive 
has left the old circuit, the coupling is released. 

Method: 

 

Press [function] or [Light] key on the controller 
or control panel.  The control LED flashes. 

 

Select the new track circuit on the controller and 
switch the light function on.  Both track circuits 
are now controlled with the settings of the first 
track circuit. 

Important:

 The DAISY system can only process 

one coupling operation.  That is, you must 
complete one coupling operation before you can 
start the next. 

 

As soon as the locomotive has reached the new 
section (circuit) the coupling in which the light 
was switched off will be released. 

Handling a short circuit 

If a short circuit occurs on the layout only the 
Power 2 connected to that circuit will shutdown. 
The shut down Power 2 can be turned back on, if: 

 

a DAISY handcontroller has the [stop] key is 
pressed 

 

a FRED for the selected track circuit has the 
[stop] key  is pressed 

 

an IB-Control has the [go] key is pressed 

 

a Profi-Control for the selected track circuit has 
the travel direction lever is set to 0 and then to 
the desired speed. 

Operation of a reversing loop on  an 
analogue layout 

Power 2 is compatible with reversing loop 
trimmings that are provided by the track 
manufacturers. 
The reversing loop automation cannot be used as 
most switch the polarity of the outer part of the 
track via a reversing switch.  In a DAISY system 
the system earth must always be on the same 
side of the track to prevent short circuits when the 
locomotive crosses to another track circuit. 

Wiring 

In order to automate or partially 
automate a reversing loop in a 
layout Power 2 uses one input to 
switch the present direction over for 
the controller.  To reverse the 
direction Pin 1 and Pin 2 of the 
booster input must be connected.  Adapter plug 
61 050 can be used for this connection. 

Important:

  The last Power 2 in the chain of 

analogue boosters - to whose LocoNet socket the 
controllers are connected – must not be fitted with 
this polarity control. 

Special functions in analogue systems 

Via the special function of each of the connected 
controllers you can achieve things in an analogue 
system that are normally only possible in digital 
systems. 

Note:

 The function only operates in the track 

circuit connected to the Power 2 for which the 
function has been activated.
