The CLX operates with the "Sensor" switching input as an external trigger source. The
reading pulse starts when the input is energized (high).
4.4.3
Mounting the sensors for detecting the object distance
If the dynamic focus control function of the CLX is triggered by external sensors, suitable
sensors must be mounted in the vicinity of the CLX.
operation from above. The sensors must be arranged in such a way that all of the potential
object heights are classified uniquely and overlapping reading ranges occur that can be
formed with the depths of field of the CLX. A maximum of five switching inputs are available
for this purpose. A max. of 32 switching states for 8 distance configurations (reading ranges)
can be implemented using the internal assignment table (combinations). Photoelectric reflex
switches, for example, can be used to detect the object distance. In the default setting, all
five "IN 0... IN 4" switching inputs are selected for dynamic focus control.
