The signal inputs are voltage-controlled which means that you will need an additional AC/DC power
source between 8(AC)/11(DC) and 24(AC/DC) V. This voltage must be fed into location (1).
The following applies to the K1 and K2 switches:

Since the "K2" switch (Slow approach) is always designed to be open when the signal is at "Slow
approach", a resistor (4k7, 1/4W), shown in the figure left, must be installed. The resistor is
enclosed with the BM2.
