Changing light/dark switching
at the product sensor or the
alternativ label sensor
Basically, sensors can be assigned to three dif-
ferent groups regarding the function of pin 2:
a) Pin 2 has no function
b) Pin 2 = input, e.g. for light/dark switching
c) Pin 2 = output, e.g. for an inverse signal
With sensors or type b), the basic switching type can be
changed by connecting pin 2 to +24 V or to ground [75].
For all other sensor types is the absolute rule: Leave
the relevant jumpers open!
Example:
The alternative label sensor pictured in [74] has an in-
verse output on pin 2. Therefore, JP 901 must be left
open.
