16.2 Timing
In principle, the individual beams are always processed sequentially for light curtains. The internal
controller starts transmitter 1 and then activates only the corresponding receiver 1 to measure the received
light power. If the measured value exceeds the switch-on threshold, this first beam is evaluated as an unin
-
terrupted/free beam.
The time between activation of the transmitter and evaluation in the receiver is referred to as the response
time per beam.
In the CML 730-PS the response time per beam is = 10 µs.
The total cycle time for the evaluation of all beams and transmission to the interface is calculated as
follows:
Cycle time = number of beams x response time per beam + constant

Industrial interference emission
This is a Class A product. In a domestic environment, this
product may cause radio interference. In this case the
operator may be required to take appropriate measures.
The minimum cycle time is 1 ms, i.e., the cycle time is never less than 1 ms, even with very short
light curtains with a small number of beams.
