Electrical Coupler Configuration
The Lokommander II decoder allows the use of any physical output for the action of electromagnetic
couplers. If a logical output is chosen it is necessary to use an external transistor, the output supplying an
insufficient current for actuating the coupler. The Krois® and Roco® couplers require a high-frequency
PWM signal supply to avoid burning of the coils of the couplings. The automatic decoupling function of the
decoder provides this command signal.
The automatic decoupling function can only be activated with the stationary locomotive.
The automatic decoupling function is a physical function (not logical, such as maneuvering speed,
inactivation of acceleration and deceleration, etc.) and must be configured accordingly. Follow these
guidelines for the configuration:
Choose an F function to be used for the automatic decoupling function (it can be a function used for
other commands, for example sound).
For the selected function (CV33÷CV47) the mapping of the physical output has to be made (the output
where the coupler is physically connected). As an example, if we choose the F8 function for automatic
decoupling and the coupler electromagnets are connected to the physical output AUX2 (purple wire), CV43
