Function
l After mains connection and simultaneous HIGH level at both inputs, the outputs are set as
follows:
Inputs Outputs
R/L/Q−R R/L/Q−L R/L/Q−R/L R/L/Q−QSP
1 1 0 1
l The following truth table results if one of the inputs is set to LOW once after mains connection:
Inputs Outputs
R/L/Q−R R/L/Q−L R/L/Q−R/L R/L/Q−QSP
0 0 0 1
1 0 0 0
0 1 1 0
1 1 unchanged unchanged
l If both inputs are set to HIGH during operation, the values at both outputs remain unchanged.
