Contact multiplication by external contactors.
The function of the external contactors is monitored by connecting the
NC contacts into the feedback circuit ST1-ST2 (for automatic restart S2
on autostart and instead of the ON button ST1-ST2 has to be bridged).

If only 1 sensor is connected to one of the sensor inputs M1/M2, the
other sensor input M3/M4 has has to be bridged with a resistor
(/10x: 1,2 kOHM ±1%; /11x: 8,2 kOhm ±1%).
