I/O1 "Left" button status (1, Fig.9)
I/O2 "Right" button status (3, Fig. 9)
I/O3 "Stop" button status (2, Fig. 9)
I/O4 "Antipanic" button status (4,Fig.9)
I / O1 ... I / O3 outputs show the current state of RC panel buttons, i.e.
transistor is opened by pressing the corresponding button. I / O4 output
changes its state to the opposite every time the "antipanic" button is
pressed.
I / O1 ... I / O4 outputs can be connected both directly to the ACS
controller or via relay. When using the relay it is necessary (!) to connect
diode in parallel with the relay coil (Fig. 10).
