5.1.1 Protective field size
The protective field must be so configured that a minimum distance (S) to the hazardous
area is maintained. This safety distance ensures that the hazardous point can only be
reached after the dangerous state of the machine has been completely stopped.
If you define several monitoring cases with different protective fields, you must calculate
the protective field sizes for all protective fields used.
You can operate the S3000 in stationary horizontal operation with 50 mm or with 70 mm
resolution. For each resolution you can choose between 60 ms and 120 ms response
time. The maximum protective field range results from the resolution and the response
time

of the S3000
If you choose a 50 mm resolution, the maximum protective field range is less than for a
70 mm resolution, however you can mount the S3000 as low as required.
If you choose a 70 mm resolution, you can configure the largest protective field range,
but you must position the scan plane of the S3000 at 300 mm.
Ensure that a human leg can be detected in horizontal stationary applications with
70 mm resolution!
Mount the scan planes for horizontal stationary applications with 70 mm resolution at a
height of at least 300 mm (see “Height of the scan plane at 70 mm resolution” on
page 72).
Due to the choice of two resolutions and two response times, it may be necessary to
repeatedly calculate the protective field size (iterative calculation).
Perform your protective field calculation initially based on a resolution of 50 mm and a
basic response time of 60 ms.
If the calculated protective field is larger than the maximum protective field range at
50 mm resolution, calculate it again using the same resolution and the higher response
time.
If the protective field calculated is larger than the maximum protective field range
achievable, then re-calculate the protective field with the coarser resolution.
The minimum distance S depends on:
approach speed of the body or parts of the body
stopping/run-down time of the machine or system (the stopping/run-down time is shown
in the machine documentation or must be determined by taking a measurement)
response time of the S3000
supplements for general measurement errors and any measurement errors related to
reflection
supplement for prevention of reaching over
height of the scan plane
possibly the time for switching between the monitoring cases
