11.2 Response time
The response time depends on the following parameters:
$ number of beams
$ beam coding
$ configuration of floating blanking
$ number of cascaded systems
How to determine the response time of the system:
Read the response times of the individual systems (shown on type label). Note whether
the system is operated with or without beam coding.
If you are planning the application without actually having any devices available, you may
also determine the response time using Tab. 26 and Tab. 27. When determining the
number of beams in Tab. 26, the physical resolution is important. The physical resolution
of the light curtain does not change even if fixed or floating blanking has been selected.
Fill out the following table to determine the total response time.
Line Required detail Response time
1 Host ms
2 Guest 1 +ms
3 Guest 2 +ms
Greatest response time from lines
1 to 3: × 0.5 =
+ms
4 Only if floating
blanking is used:
Deduct 4 ms here. –ms
5 If single guest is used, then add 8 ms here. (If no guest is
used or two guests are used, do not add anything here.)
+ms
6 Total response time to be taken into account
(The total response time must be ≤ 108 ms!) =ms
Verify that the total response time determined is ≤)108 ms. EN 61)496 does not permit
response times exceeding 108 ms. If necessary, adjust the configuration.

Depending on load, power supply and wire cross-section. The technical specifications must be observed.
