Light source Receiver
The system outputs V
max
if no
object blocks any light and
the receiver is fully exposed.
The voltage
V
max
can be set via
the gain potentiometer and
typically should read 10 V.
As the light for the receiver
decreases the signal drops
linear according to light
quantity.
If the light curtain is fully cov-
ered by a target the receiver
outputs a signal of 0 V.

Take care on target orien-
tation to avoid measure-
ment errors!
