3 FUNCTIONAL DESCRIPTION
3.1 Block diagram
At power-up by an energy pulse at AC1, AC2 a DC voltage is provided to the internal micro
controller. The microcontroller reads the polarity of the supply voltage pulse and the status
of the digital inputs A0, A1, B0, B1. After that 3 identical radio telegrams calculated from
the status of these inputs are transmitted.
