[f1], [f2] Startup Inertia mode selection  

[f1] off, [f2] off = no inertia control 
[f1] on, [f2] off = next higher setting 
[f1] off, [f2] on = medium setting 
[f1] on, [f2] on = maximum operation 

[f3] Shunting 

[f3] off = shunting active 
[f3] on = shunting inactive 

[f4] Startup inertia on/off 

[f4] off = inertia activated 
[f4] on = inertia deactivated e.g. for shunting 

[f5] Motor control 

[f5] off = PWM frequency of 104 Hz to control 

conventional DC motors 

[f5] on = PWM frequency of 16.7 KHz to control 

bell armature DC motors 

[f7] Operation of reversing loop 

[f7] off = closing the switch reverses the direction 
 

opening the switch reverses the direction 

[f7] on =  closing the switch reverses the direction 

opening the switch does not reverse the 
direction 

Turnout booster in analogue layouts 

Power 2 booster can be installed to control 
turnouts and signals fitted with decoders in DCC 
format and controls them via LocoNet devices 
without the need of a central digital controller. 
In this way a Power 2 can be used as a turnout 
booster or in a DAISY system, together with an 
IB-Switch or Switch-Control as a digital turnout 
control system, in a conventional layout.  With the 
IB-Switch or Switch-Control turnouts, signals and 
routes can be switched. 
In order for turnouts to function correctly after a 
power down of the LocoNet control panels, in this 
type of installaton, it must have at least one 
DAISY handcontroller connected. This 
handcontroller must be configured so that it saves 
the turnout settings when the layout is turned off 

(see chapter “Special Options” in the DAISY 
manual). 
If the Power 2 without a DAISY handcontroller is 
connected with an IB-Switch or Switch-Control the 
state of turnouts will not be displayed after a 
powerdown.  The LEDs will only indicate after the 
turnout has been switched once. 

Turnout booster wiring 

To operate a Power 2 as a turnout booster Pin 1 
and Pin 2 must be connected.  Adapter 61 050 
can be used for this purpose. 

 

Connect Power 2 to a separate transformer (e.g. 
20 040).  The track connectors are used connect 
the decoders. 
If the Power 2 turnout booster is to be used in a 
DAISY system on an analague layout, it is 
connected into the systems daisy chain as shown 
in the previous section.  The last booster in the 
chain must have the controllers connected to it.  
To this booster you can connect the IB-Switch, or 
Switch-Control as a turnout controller. 
Turnout addresses in the  range 1 to 1024 are 
supported. 
The preset turnout switching time of 1.3 seconds 
can be saved for the selected track circuit by 
pressing [f7] on the controller.
