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 M4000 multiple light beam
safety device or with the machine protected by the M4000 multiple light beam safety
device.
2.1 Specialist personnel
The M4000 multiple light beam safety device must only be installed, commissioned and
serviced 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 M4000 system is a type 4 electro-sensitive protective equipment (ESPE) as defined by
IEC/EN 61496@1 and IEC 61496@2 and is therefore allowed for use with controls in
category 4 according to EN 954@1. The preconfiguration of the M4000 multiple light beam
safety device is suitable for:
• hazardous area protection
• access protection
The multiple light beam safety devices must be installed such that the hazardous area can
only be reached by interrupting the light path between sender and receiver. It must not be
possible to start the plant/system as long as personnel are within the hazardous area.
The M4000 system is intended only for use in industrial environments. When used in
residential areas it can cause interference.
Refer to page 15 for an illustration of the protection modes and an example application.
WARNING
Only use the multiple light beam safety device 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 protective devices may be required in addition
to the M4000 system.
