Figure 1.1: Definition of terms
GUI (Graphical User Interface)
Graphical user interface
PS (Power Setting)
Separate adjustment of the transmitter/receiver relative to
transmitting power and receiving sensitivity.
PLC
Programmable Logic Control
(corresponds to Programmable Logic Controller (PLC))
Response time per beam
Length of time for the evaluation of a beam
Resolution
The minimum size of an object that can be reliably detected.
With parallel-beam evaluation, the smallest object to be
detected corresponds to the sum of beam spacing and optic
diameter.
Delay before start-up
Duration between the switching on of the supply voltage and
the start of operational readiness of the light curtain
Function reserve (sensitivity adjust
-
ment)
Ratio of the optical reception power set during the teach event
and the minimum light quantity required to switch the individual
beam. This compensates for the light attenuation caused by
dirt, dust, smoke, humidity and vapor.
High function reserve = low sensitivity
Low function reserve = high sensitivity
Measurement field length
Optical detection range between the first and last beam
Beam spacing
Center-to-center spacing between two beams
Cycle time
Sum of the response times of all beams of a light curtain plus
the duration of the internal evaluation.
Cycle time =
number of beams x response time per beam + evaluation time
