[Stop] key 

The [Stop] key can be used for turning off/on power to the layout. If the 
layout power is off, the display shows 4 blinking decimal points. 

[function] and [off] keys 

The [function] key starts the coupling of two electric circuits. This allows 
a locomotive to smoothly pass from one electric circuit (supplied by a 
specific Power2) to a different electric circuit (driven by a different 
Power2). The coupling also transfers all locomotive features (e.g., 
acceleration and deceleration factors) from the first to the second 
Power2. The [off] key is used to terminate the coupling, effectively de-
coupling the two Power2’s. 

Functions in analog mode 

In drive mode, the function keys (f1 through f4) can be used to control 
features pertaining to the driving characteristics of analog locomotives. 
Each Power2 (each electric circuit) has its own setting, which is 
independent of the setting applied to other Power2’s. 

[f1], [f2] acceleration/deceleration delay 

[f1] off, [f2] off = minimum acceleration/deceleration delay 
[f1] on, [f2] off = low acceleration/deceleration delay 
[f1] off, [f2] on = medium acceleration/deceleration delay 
[f1] on, [f2] on = maximum acceleration/deceleration delay 

(Note: minimum delay means that a locomotive will react very quickly to 
speed changes). 

[f3] switching speed (i.e., half speed) 

[f3] off = normal speed 
[f3] on = switching speed (half of normal speed) 

[f4] enable/disable acceleration/deceleration delay 

[f4] off = acceleration/deceleration delay is enabled 
[f4] on = acceleration/deceleration delay is disabled 

[f5] motor control (low or high frequency) 

[f5] off =  low frequency (104 Hz) PWM (Pulse Width Modulation) 

(e.g., for normal motors) 

[f5] on =  high frequency (16.7 KHz) PWM (Pulse Width Modulation)

(e.g., for coreless or Faulhaber motors) 

[f7] loopback control

 (check Power2 manual) 

[f7] off =  closing the contact changes driving direction 

opening the contact changes driving direction 

[f7] on =  closing the contact changes driving direction 

opening the contact does 

not

 change driving direction 

In turnout mode, these keys allow controlling four turnouts at a time. 
The four LEDs show the status of the corresponding turnout, indicating 
either ‘green’ or ‘red’.
