2 On safety
This chapter deals with your own safety and the safety of the equipment operators.
Please read this chapter carefully before working with the C 4000 or with the machine
protected by the C 4000.
2.1 Specialist personnel
The safety light curtain C 4000 must be installed, commissioned and serviced only by
specialist personnel. Specialist personnel are defined as persons who
$ have undergone the appropriate technical training
and
$ who have been instructed by the responsible machine operator in the operation of the
machine and the current valid safety guidelines
and
$ who have access to these operating instructions.
2.2 Applications of the device
The safety light curtain C 4000 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
300 and 1,800 mm.
The device is a Type 4 ESPE as defined by IEC 61)496-1 and -2 and is therefore allowed for
use with controls in control category 4 in compliance with EN 954-1. The emergency stop
monitoring in the device corresponds to stop category 0 in accordance with EN 418. 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 15 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 C 4000 operates as a standalone system, comprising a sender and
receiver, or in combination with other cascadable C 4000 systems. This means that the
protective field can be adapted to suit individual safety requirements.
