After finishing the wiring, mount the circuit board with the
pad included for this purpose. Make sure that the circuit
board cannot cause a short circuit.
Before you plug the decoder in, it must be programmed
correctly.
Outputs 3 (forwards) and 4 (reverse) must be active for
the pickup shoe changeover. The setting for this is done in
mDT3 be means of the function activator „ALWAYS" and
„Action to ALWAYS". The programming here depends on the
wiring, and it may be necessary to swap the outputs in the
functions.
