1 System Overview and Scope of Applications
1.1 General
The COMPACT safety light curtains and light grids are active optoelectronic
protection devices (AOPD) of the type 4 according to IEC 61496-1, -2 and
EN 61496-1, -2. A two-dimensional protective field of infrared radiation is
generated between transmitter and receiver. Penetrating this protective field
will trigger the safeguarded machine to go into a safe mode before the person
can enter a potentially hazardous area.

1.5 Deflection Mirrors
A hazard location or a danger area can be guarded on more than one front by employing deflection
mirrors. The maximum possible width of the protection zone is reduced for each mirror accordingly
as shown in the following table. The use of more than two mirrors is not to be recommended
because of the difficulties associated in the alignment.

2 Notes on Safety
2.1 General Hazards for Non-observance of Notes on Safety
Care is exercised in accordance with recognised codes of engineering practice in the development
and production of Leuze lumiflex products. The protection function of the equipment can however
be impaired if the units are not used in accordance with their intended application or are not used
properly. Such instances can cause hazards for the health and life of the personnel operating the
machinery. Safety light curtains and light grids do not provide protection against injuries resulting
from flying objects.
2.2 Use according to Intended Applications
For use in the foodstuffs industry and in explosion-endangered areas, the COMPACT is not suitable
in its standard design. Special housings on request.
2.3 Operating Conditions
Applicable regulations (e. g. machinery-specific C-Standards in the EU or the OSHA and ANSI
standards in the USA) apply for the use and installation of COMPACT safety light curtains and light
grids. The appropriate authorities for the country in question are available for answering questions
regarding safety engineering. In general, compliance with the following operating is required:
•The COMPACT units shall be installed such that access from above, beneath or behind the pro-
tected field is ruled out. If this is not assured, then additional protection measures must be
installed
COMPACT equipment type Use according to intended
application

Light curtain, series C30 Hand protection
Light grid, series C50 and C90 Horizontal guard over areas of
danger, detection of a person

52 COMPACT Leuze lumiflex
Fig. 4 Access from above, beneath or behind must be ruled out
•Intervention in the controls of the machine by electrical means must be possible so as to enable
immediate termination of potentially hazardous states in each working phase.
•The safety clearance between hazard location and protection zone must be
sufficiently large enough such that the potentially hazardous state is terminated before the person
has reached the hazard location (refer to 4.1).
•The mechanical and electrical installation shall be carried out by trained and qualified personnel.
The switching outputs of the COMPACT (OSSD’s) shall be connected as two-channel outputs to
the shutoff path for the potentially hazardous condition (refer to 5.1 and 5.2).
3 Design and Function
3.1 System Overview
The COMPACT equipment consists of transmitter and receiver. The transmitter consists of the con-
trol electronics and a modular arrangement of IR-radiation sources which are sequentially triggered
in quick succession and send out coded infrared pulses. The receiver consists of a control and eval-
uation assembly with the switching outputs and modular IR reception elements which are evaluated
in synchronisation with the transmitter. The synchronisation is realised by optical means. Intercon-
nection of both components by a cable is not necessary. The control assemblies are identical for all
COMPACT models, the IR transmitter and reception modules differ however in their radiation range
and optical characteristics. Each component is housed in a robust aluminium profile casing of stand-
ard design and is powered by 24 V DC.
