To the interrupt put of the 2 uc in 3) the salsa from the Actinite are counted. From the ipiesane! filter R 874 C 872 the: HIGH LOW
transition (connection "pulse") is freed of any superimposed interferences. The diodes D 872, D 873 and D 874 limit the signal to the
transistors T 871, T 873 and signal, with an amplified edge steepness, reaches IC 800.
