Mounting
This chapter describes the preparation and completion of the mounting of the SC300
safety camera system. Mounting requires the following steps:
• Checking the dimensions of the protective field (see below)
• Determining the safety distance (see page 16)
• Mounting of the camera (see page 20)
• Mounting the reflective tape (see page 24)
The following steps are necessary after mounting:
• Completing the electrical connections (see Chapter 5 on page 27)
• Testing the installation (see “Test Notes” section on page 38)
Checking the dimensions of the
protective field
Note Applicable to all resolutions:
• The ratio of the lengths of the sides of a protective field monitored must not exceed
2:1.
• If you require a larger protective field than is possible with a single SC300, you can
mount two SC300 in parallel in opposite directions. In this way you can generate two
overlapping protective fields (see “Application with two SC300” on page 35).
Protective field dimensions allowed at a resolution of 20 mm
The lengths of the sides of a protective field monitored must not be shorter than 0.40 m
and not longer than 1.00 m.
Table 5 - Protective field dimensions allowed for a rectangular protective field at a resolution of
20 mm (intermediate values are allowed)
Example 1: The shorter side is 0.43 m long. Then the longer side must be at least 0.43 m
and is allowed to be a maximum of 2 × 0.43 m = 0.86 m long.
Example 2: The shorter side is 0.78 m long. Then the longer side must be at least 0.78 m
and is allowed to be a maximum of 1.00 m long.
Only use the SC300 safety sensor system if the ratio allowed for
the lengths of the sides of the protective field can be met.
If the maximum ratio of the lengths of the sides is exceeded, the
safety sensor system may not operate correctly. This would mean
that the operator is at risk.
ATTENTION
