State
Flashing light Detection of the components via LED is activated (p0154).
Note:
Both options depend on the LED status when module recognition is
activated via p0154 = 1.
On The controllable sensor power supply is functioning fault-free.
Steady light There is a fault in the controllable sensor power supply.
On The sensor power supply is operating fault-free.
Steady light The sensor power supply has a fault.
NC contact/NC contact
Steady light Different signal states at input x and x+1
– No signal at input x and no signal at input x+1
NC contact/NO contact
Steady light Same signal states at input x and x+1
– No signal at input x and no signal at input x+1
NC contact/NC contact
Steady light One signal at input x and one signal at input x+1
NC contact/NO contact
Steady light One signal at input x and no signal at input x+1
Off No signal at digital input x (x = 20 ... 23)
Steady light Signal at digital input x
Steady light Output y (y = 0 ... 3) has an active signal
Off One of the two output lines y+ or y- or both lines of output y carry a
signal
Steady light Both output lines y+ and y- carry no signal
