2.2 Applications of the device
T
he safety light curtain C4000 is an item of electro-sensitive protective equipment (ESPE).
The physical resolution is 14, 20, 30 or 40 mm with a maximum protective field width of
19 metres (resolution 20 mm and higher). The realisable protective field height is between
3
00 and 1,800 mm.
The device is a Type 4 ESPE as defined by EN 61496C1 and IEC 61496C2 and is therefore
allowed for use with controls in category 4 according to EN ISO 13849C1. The emergency
stop monitoring in the device corresponds to stop category 0 in accordance with
EN ISO 13850. The device is suitable for:
 hazardous point protection (finger and hand protection)
 hazardous area protection
 access protection
Access to the hazardous point must be allowed only through the protective field. The
plant/system is not allowed to start as long as personnel are within the hazardous area.
Refer to chapter 3.3 “Examples of range of use” on page 17 for an illustration of the
protection modes.
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 protection devices may be required in addition
to the safety light curtain.
The safety light curtain C4000 operates as a standalone system, comprising a sender and
receiver, or in combination with other cascadable C4000 systems. This means that the
protective field can be adapted to suit individual safety requirements.
2.3 Correct use
The C4000 safety light curtain must be used only as defined in section 2.2 “Applications of
the device”. It must be used only by qualified personnel and only on the machine where it
has been installed and initialised by qualified safety personnel in accordance with these
operating instructions.
If the device is used for any other purposes or modified in any way-also during mounting
and installation-any warranty claim against SICK AG shall become void.
