NOTE
Hysteresis (H on function diagrams): 5V.
Power-on activation time: 1s.
Switch-on lock-out time: 0.5s.
Positive safety logic - Make output contact opens if the relay 
detects an error.

To reset, It is necessary to switch the supply OFF and then ON
again (U OFF U ON) or to rotate the function selector first to an 
adjacent position and then to the original position.
