Depending on the specified values you can work with the above-mentioned table in three ways:
1. Given are:
• Height a of the point of operation
• Distance S of the point of operation from the safety sensor, and additional distance C
To be determined is the required height b of the upper beam of the safety sensor and thereby its protective
field height.
Ä Look for the line with the specification of the point of operation height in the left column.
Ä In this line, look for the column with the next highest specification for additional distance C
ð The required height of the upper beam of the safety sensor is up top in the column head.
2. Given are:
• Height a of the point of operation
• Height b of the upper beam of the safety sensor
To be determined is the required distance S of the safety sensor to the point of operation and thereby addi-
tional distance C
Ä In the column head, look for the column with the next lowest entry for the height of the upper beam of
the safety sensor.
Ä Look for the line with the next highest specification of the point of operation height a in this column.
ð In the intersection point of the line and the column, you will find additional distance C
3. Given are:
• Distance S of the point of operation from the safety sensor, and additional distance C
• Height b of the upper beam of the safety sensor
To be determined is the permitted height a of the point of operation.
Ä In the column head, look for the column with the next lowest entry for the height of the upper beam of
the safety sensor.
Ä Look for the next lowest value for real additional distance C
ð In this line, go to the left column: here you will find the permitted height of the point of operation.
Ä Now calculate safety distance S using the general formula acc. to ISO 13855 (see chapter 6.1.1 "Cal-
culation of safety distance S").
ð The larger of the two values S
