Teach mode [requires: P1 = 0, P2 = 0] Error Correction
for Learn cycle and "Start" cycle with learned position
P1 ≠ 0, P2 ≠ 0
P1 = 0, P2 = 0
Switch mode [requires: 0 ≤ P1 < P2 ≤ 93.75]
Error Correction
Signal to "Teach" without effect, only "Start" pulse !
for object monitoring (S1 = 0) or
P2 = 0 P2 > 0
for free space monitoring (S1 = 1)
P1 = P2 P1 < P2
P1 > P2 P1 < P2
