2.2 Applications of the device
The C4000 safety light curtain is an item of electro-sensitive protective equipment (ESPE).
The C4000 consists of a sender and a receiver (Fig. 1 and Fig. 2). Between the two is the
protective field.
T
he size of the C4000 defines the protective field length in horizontal applications, the
protective field height in vertical applications. The effective protective field length or pro-
tective field height is between 300 and 1800 mm.
The protective field width is given by the dimension of the light path between sender and
receiver (see “Technical specifications” on page 95).
The physical resolution is 20, 30 or 40 mm.
The device is a Type 4 ESPE as defined by IEC 61496E1 and IEC 61496E2 and is therefore
allowed for use with controls in category 4 PL e according to EN ISO 13849E1 and SIL3
according to IEC 61508.
The emergency stop monitoring in the device corresponds to stop category 0 in accor-
dance with EN ISO 13850. The C4000 Palletizer Standard/Advanced and the C4000
Fusion are suitable for:
hazardous area protection
access protection
In addition, the C4000 Fusion is suitable for:
hazardous point protection
For hazardous area protection or access protection, the C4000 is used for the protection
of hazardous areas that can be entered on foot. Access can be directly via corridors (e.g.
the building floor) or via conveyors (e.g. roller conveyors or chain conveyors).
Access to the hazardous point must be allowed only through the protective field. The
plant/system must not start as long as personnel are within the hazardous area. Refer to
chapter 3 “Product description” on page 13 for an illustration of the protection modes.
You will find a description of the default delivery status in section 9.1 “Default delivery
status” on page 88.
Only use the safety light curtain as an indirect protective measure!
An opto-electronic protective device provides indirect protection, e.g. by switching off the
power at the source of the hazard. It cannot provide protection from parts thrown out, nor
from emitted radiation. Transparent objects are not detected.
Depending on the application, mechanical guards may be required in addition to the safety
light curtain.
