An impulse converter can be added to a SCHAEFER display. It converts serial pulses to dual code.

Crep code
The crep code defines different pulse packages for the floors. The number of pulses within one package determines the floor position to be displayed. The travel direction signals and the travel signal are displayed independently from the crep code. As the crep code has no fix definition it should be checked prior to ordering whether the Impulswandler matches with the controller.
Impulse + Ref
The selection of the floor display is done by a travel direction/floor change and reference signal. If a reference impulse is detected, always the address with the lowest order will be displayed. With each floor change impulse the floor display will increase by one position with active signal “up” and decrease by one position with active signal “down”.
Double pulse
The floor indicator requires two impulse signals and one reference signal. Upon detection of a reference impulse, always the address with the lowest value is indicated. If first the floor change impulse 1 and then the floor change impulse 2 is detected, the floor indication is increased by one. If first impulse 2 is detected, the floor indication is decreased by one.
