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 spe-
cialist personnel. Specialist personnel is 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 currently valid safety guidelines
and
·
who have access to these operating instructions
2.2
Range of uses of the device
The safety light curtain C 4000 is an electro-sensitive protective equipment (ESPE). The
physical resolution is 14, 20, 30 or 40 mm with a maximum protective field width of 19 me-
ters (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 61496-1 and -2 and is therefore allowed for
use with controls in safety category 4 in compliance with EN 954. The device is suitable for
·
Hazardous point protection (finger and hand protection)
·
Hazardous area protection
·
Access protection
Access to the hazardous area 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 12 for an illustration of the protection
modes.
Depending on the application, mechanical protection devices may be required in addition
to the safety light curtain.
Note
The safety light curtain C 4000 operates as 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.
2.3
Proper use
The safety light curtain C 4000 must be used only as defined in the chapter 2.2 “Range of
uses of the device”. It must be used only by qualified personnel and only on the machine
where it has been installed and initialized by qualified personnel.
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.
